Answer:
1.) Volume= Whereas the basic formula for the area of a rectangular shape is length × width, the basic formula for volume is Length × Width × Height
2.) Terms in this set (4)
Measure 50 ml of water into a gradulated cylinder.
Place object in cylinder and measure the new volume.
Subtract the 50ml from the new volume.
The difference in the volume is the volume. of the object.
3.) Graduated cylinders
4.) Particles behave differently within each state of matter: solid, liquid, and gas. The particles give matter a property called mass. The mass of an object is related to the amount of material that makes up the object and how hard the object is to move. Simple experiments can show how gases have mass.
Explanation:
1.) Volume is the quantity of three-dimensional space enclosed by a closed surface, for example, the space that a substance (solid, liquid, gas, or plasma) or shape occupies or contains. Volume is often quantified numerically using the SI derived unit, the cubic metre.
SI unit: Cubic metre
In SI base units: 1 m3
2.) If the object has an irregular shape , the volume can be measured using a displacement can . The displacement can is filled with water above a narrow spout and allowed to drain until the water is level with the spout. As the irregular object is lowered into the displacement can, the water level rises.
3.) Today they will practice measuring different liquids. They will use a container called a graduated cylinder to measure liquids. Graduated cylinders have numbers on the side that help you determine the volume. Volume is measured in units called liters or fractions of liters called milliliters (ml).
4.) Mass is a measure of the amount of matter in an object. Mass is usually measured in grams (g) or kilograms (kg). ... An object's mass is constant in all circumstances; contrast this with its weight, a force that depends on gravity. Your mass on the earth and the moon are identical.

The degrees of the given dimensions are degree of length= 1 ,degree of width = 1 , degree of height= 3 , degree of volume = 5
To determine the degree of each dimension and the volume for Box 2, let's consider the expressions:
Length = (4x - 1)
Width = x
Height = x³
Volume = Length × Width × Height
Volume = (4x - 1) × x × x³
Now, let's simplify the volume expression:
Volume = (4x² - x) × x³
Volume = 4x⁵ - x⁴
Now, let's find the degrees of each dimension and the volume:
Degree of length:
The degree of the length dimension is the highest power of x in the expression (4x - 1). The highest power of x in this expression is 1.
Degree of width:
The degree of the width dimension is the highest power of x in the expression x. The highest power of x in this expression is 1.
Degree of height:
The degree of the height dimension is the highest power of x in the expression x³. The highest power of x in this expression is 3.
Degree of volume: The degree of the volume is the highest power of x in the expression 4x⁵ - x⁴. The highest power of x in this expression is 5.
Therefore, the degrees are as follow,
Degree of length: 1
Degree of width: 1
Degree of height: 3
Degree of volume: 5

The units of the floor plan at the right are in feet. Find the
perimeter and area of each room.
a. the kitchen
Kitchen
Bedroom
b. the bedroom
c. the bathroom
20 ft
Main
hallway
d. the closet
Closet
Bathroom
e. What is the area of the main hallway? Explain how
you could find this area using the area of each room
20 ft
Answer:
Step-by-step explanation:
a). Perimeter of the kitchen = total length of all sides
= 4 + 2 + 2 + 6 + 6 + 12 + 10 (Since side of one smallest square = 2 feet)
= 42 ft
Area of the kitchen = Area of the composite figure
= 4² + 2² + (6 × 12)
= 16 + 4 + 72
= 92 square feet
b). Perimeter of bedroom = 2(length + width)
= 2(12 + 8)
= 40 feet
Area of the bedroom = Length × Width
= 12 × 8
= 96 square feet
c). Perimeter of the bathroom = 2(9 + 4) = 26 feet
Area of the bathroom = 9 × 4 = 36 square feet
d). Perimeter of the closet = 2(6 + 8) = 28 feet
Area of the closet = 6 × 8 = 48 square feet
e). Area of the hallway = Total area of the floor plan - area of the (kitchen + bathroom + bedroom + closet)
Area of the floor plan = 20 × 20 = 400 square feet
Area of the hallway = 400 - (92 + 96 + 36 + 48)
= 400 - 272
= 128 square feet

yes it represents a function cause it passes the vertical line test.
Which of the following rules describes the function graphed below? On a coordinate plane, points are at (1, 5), (2, 4), (3, 3), (4, 2). a. Output = Input c. Output = 5 · Input - 4 b. Output = Input - 4 d. Output = 6 - Input Please select the best answer from the choices provided A B C D
*see attachment
Answer:
D. Output = 6 - Input
Step-by-step explanation:
The output is the y-value, while the input is the x-value. The coordinates are represented as (x, y), and are graphed in the figure attached below.
Let's consider the function and see which rule best describes the function.
Considering the point (1, 5), the rule, output = 6 - input, applies.
Let's check it out:
Output is 5, input is 1. Substitute 1 as input into the rule, Output = 6 - input, and see if it would give you 5 as output:
Output = 6 - 1
Output = 5
If you try another coordinate pair of the function, the same rule will apply.
Therefore, the best answer is D. Output = 6 - Input

Time (weeks) n 1 2 3 4 Savings account balance ($) f(n) 260 360 460 560 Determine the value of f(11) and tell what it represents in this situation. f(n) = + (n − 1) f(11) = After 11 weeks, Darnell′s savings account will have a total of $ .
Answer:
After 11 weeks, Darnell′s savings account will have a total of $8,360.
Step-by-step explanation:
The data provided is as follows:
n: 1 2 3 4
f (n): 260 360 460 560
Consider the data for f (n).
The series f (n) follows an arithmetic sequence with a common difference of 100 and first term as 260.
The nth term of an arithmetic sequence is:
[tex]a_{n}=\frac{n}{2}[2a+(n-1)d][/tex]
Compute the value of f (11) as follows:
[tex]f(11)=\frac{11}{2}[(2\times260)+(11-1)\times 100][/tex]
[tex]=5.5\times[520+1000]\\\\=5.5\times 1520\\\\=8360[/tex]
Thus, after 11 weeks, Darnell′s savings account will have a total of $8,360.

[PLEASE ANSWER ASAP, ON TIME LIMIT!] The pH level of a substance can be determined by the formula pH = –log[H+], where [H+] is the hydrogen ion concentration in moles per liter. An alkaline substance has a pH level between 7 and 14. Which ion concentration corresponds to an alkaline substance?
Answer choices in picture.
Answer:
Option (2)
Step-by-step explanation:
pH level of a substance is determined by the formula,
pH = - log[H+}
where [H+] is the hydrogen ion concentration
Let the [H+] ion concentration = a
a = -log[H+]
log[H+] = -a
[H+] = 1 × [tex]10^{-a}[/tex]
Here 'a' is between 7 and 14.
Which means an alkaline substance must have the concentration between [tex]1\times 10^{-7}[/tex] to [tex]1\times 10^{-14}[/tex].
From the given options, [tex]5\times 10^{-12}[/tex] moles per liter lies in the given range.
Therefore, Option (2) will be the answer.

Answer:
She should get $23.6 in change
Step-by-step explanation:
You add the two items she bought which makes up $89.94, then you subtract the discount of $13.50, which leaves you with 76.44 to pay. If you pay with a 100 dollar bill, you subtract 76.44 from 100 in order to find out how much change you recieve.
Answer:
Step-by-step explanation:
100-((39.95+49.99)-13.50)=
100-(89.94-13.50)=
100-76.44=
23.56
You have to add the amount she is paying for the total then subtract that by the discount. Then subtract how much she gave them by the cost to get the change!
John and Jane went to a bakery to get cookies for a party. Jane bought x cookies that were $3 each. John bought x cookies that were on sale for $1 plus he got a small cake for $10.00. How much did John and Jane each spend, if they spent the same amount of money?
Answer:
They spent $15.
Step-by-step explanation:
It's given that Jane bought x cookies, so 3x.
John spent $1 on each of the x cookies he got, and also an extra $10, so x+10.
3x=x+10
2x=10
x=5
So they got 5 cookies each.
5 cookies x $3= $15 (check with $5(1)+$10= $5+$10= $15 )

closed circle on -3 and all numbers to the right shaded
open circle on -3 and all numbers to the right shaded
open circle on -3 and all numbers to the left shaded
Answer:
The second one
Step-by-step explanation:
The true statement about the graph of x > -3 is open circle on -3 and all numbers to the right shaded.
What is Number system?A number system is defined as a system of writing to express numbers.
A number line is a picture of a graduated straight line that serves as visual representation of the real numbers.
The given inequality is x>-3.
The value of x should be greater than -3.
The value -3 is not included.
In a number line the values are increased from left to right.
As x is greater than -3 which means the x values are increasing from left to right.
So the statement open circle on -3 and all numbers to the right shaded is true statement.
Hence, the true statement about the graph of x > -3 is open circle on -3 and all numbers to the right shaded.

Write the word sentence as an equation. Then solve.
10 more than a number c is 3.
Answer:
10 +c=3
C=3-10
C=-7
.....
Answer:
c = -7
first, make the equation.
10 more than a number c is 3
the variable is c, according to the sentence.
c
"10 more than a number c"
c + 10
"10 more than a number c is 3 "
c + 10 = 3
now that you have your equation, time to solve it.
it's important to know that if you do something to an equation, as long as you do it to both sides the equation is still true.
for example.
2 + 2 = 4
if you add 1 to both sides of the equation,
2 + 2 + 1 = 4 + 1
5 = 5
this is still true.
Solving the equation.c + 10 = 3
subtract 10 from both sides of the equation.
c + 10 - 10 = 3 - 10
c = 3 - 10
c = -7

This is equivalent to 2*sqrt(34)
=======================================================
Explanation:
First let's find BD
The three triangles are similar, allowing for the proportion to be set up
AD/BD = BD/DC
9/x = x/8
9*8 = x*x
x^2 = 72
x = sqrt(72)
BD = sqrt(72)
Now we can use the pythagorean theorem. Focus on triangle BDC.
The legs are BD = sqrt(72) and DC = 8. Let's find the hypotenuse
(BD)^2 + (DC)^2 = (BC)^2
(sqrt(72))^2 + (8)^2 = m^2
72 + 64 = m^2
136 = m^2
m^2 = 136
m = sqrt(136)
We can simplify this but your teacher has chosen not to. If you want to simplify, then,
m = sqrt(136)
m = sqrt(4*34)
m = sqrt(4)*sqrt(34)
m = 2*sqrt(34)
y = -4x – 5
y = -2x + 10 solve using substitution show work please
Answer:
(- [tex]\frac{15}{2}[/tex], 25 )
Step-by-step explanation:
Given the 2 equations
y = - 4x - 5 → (1)
y = - 2x + 10 → (2)
Substitute y = - 2x + 10 into (1)
- 2x + 10 = - 4x - 5 ( add 4x to both sides )
2x + 10 = - 5 ( subtract 10 from both sides )
2x = - 15 ( divide both sides by 2 )
x = - [tex]\frac{15}{2}[/tex]
Substitute this value into either of the 2 equations and evaluate for y
Substituting into (2)
y = - 2(- [tex]\frac{15}{2}[/tex] ) + 10 = 15 + 10 = 25
Solution is ( - [tex]\frac{15}{2}[/tex], 25 )
