a sphere of volume 4851 cm cube then what is the diameter?
Answer:
21 cm
Step-by-step explanation:
V = (4/3)(pi)r^3
(4/3)(3.14)(r^3) = 4851 cm^3
r^3 = 1158.1 cm^3
r = 10.5 cm
d = 2r = 2(10.5 cm) = 21 cm
An art student uses a roll of wallpaper to decorate two gift boxes. The student will use 3 1 3 yards of paper for one box and 5 6 yard of paper for the other box. The paper must be cut into pieces that are 1 6 yard long. How many pieces will the student cut to use for the gift boxes?
Answer:
25 pieces
Step-by-step explanation:
Given
[tex]Box_1 = 3\frac{1}{3}[/tex]
[tex]Box_2 = \frac{5}{6}[/tex]
[tex]Pieces = \frac{1}{6}[/tex] yard
Required
Determine the number of pieces
First, we need to determine the total yards of paper
[tex]Total = Box_1 + Box_2[/tex]
[tex]Total = 3\frac{1}{3} + \frac{5}{6}[/tex]
[tex]Total = \frac{10}{3} + \frac{5}{6}[/tex]
[tex]Total = \frac{20 + 5}{6}[/tex]
[tex]Total = \frac{25}{6}[/tex]
Divide by the size of the pieces to get the number of pieces
[tex]Number = Total/Pieces[/tex]
[tex]Number = \frac{25}{6} / \frac{1}{6}[/tex]
[tex]Number = \frac{25}{6} * \frac{6}{1}[/tex]
[tex]Number = \frac{25}{1} * \frac{1}{1}[/tex]
[tex]Number = 25[/tex]

Josiah cell phone plan allows a number of minutes of air time for $20 a month each minute costs 0.02 $ how many minutes of air time is he allowed?
Given parameters:
Cost of cell phone plan per minute = 0.02$/min
Amount in a month = $20
Unknown:
Number of minutes allowed per month?
Solution:
The number of minutes = [tex]\frac{amount per month}{rate per call}[/tex]
Input the parameters and solve;
= [tex]\frac{20}{0.02}[/tex]

The grasshopper jumps either one block to the north, or one block to the west. He needs to reach the point that is located four blocks west and three blocks north of his current position. The grasshopper needs to avoid two dangerous intersections. The first intersection is one block west and one block north of his current position, and the second intersection is two blocks west and two blocks north of his current position. In how many ways can the grasshopper reach the desired destination?
Please help, im kinda new here, so I need answers immediately, I hope brainy doesn't fail me!
Answer:
The number of ways the grasshopper can reach the desired destination are 9 ways
Step-by-step explanation:
The directions in which the grasshopper can jump are;
One block north and one block west
By counting, we have;
The number of possible ways are through blocks
1) 1, 2, 5, 6, 8, 10
2) 1, 2, 5, 6, 8, 9
3) 1, 2, 5, 6, 7, 9

The number line below represents which combined inequality? (10 points)
number line with a closed circle on negative 6 and 5 with shading in between
x greater than or equal to −6 or x less than or equal to 5
x greater than or equal to −6 and x less than or equal to 5
x less than or equal to −6 and x greater than or equal to 5
x less than or equal to −6 or x greater than or equal to 5
Answer:
x is greater than or equal to −6 and x less than or equal to 5 (second option).
Step-by-step explanation:
This would be written as an "and" inequality; -6[tex]\leq[/tex]x[tex]\leq[/tex]5. Because the circle is closed on the number line, x is greater than or equal to −6 and x less than or equal to 5, and that's pretty much the answer!
Hope this helps!!!! Have an awesome day :3
Write each equation in y = mx + b form.
1. x - y = 4
2. 2x + y = 9
Answer:
1. y=x-4
2. y=-2x+9
Step-by-step explanation:
x-y=4
-x -x
-y=-x+4
÷-1 ÷-1
y=x-4
2x+y=9
-2x -2x
y=-2x+9
3(x + 6) — 2(x + 2) > 10
Answer:
x > -4
Step-by-step explanation:
Step 1: Simplify both sides of the inequality.
x + 14 > 10
Step 2: Subtract 14 from both sides.
x + 14 − 14 > 10 − 14
x > −4

Maurice's shirt has five buttons that are vertically arranged and equally spaced. His shirt is shown in the photo below. The first and last buttons are 15.25 inches apart when measured from the top of the first button to the top of the last button. What is the distance, in inches, between the top two buttons on his shirt, from the top of one to the top of the other? Round your answer to the nearest tenth.
Answer:
The distance between the top two buttons on his shirt is 3.8 inches.
Step-by-step explanation:
Maurice's shirt has 5 buttons. Distance between first and last button is 15.25.
If we see, they would be arranged like
*
*
*
*
*
They are equally spaced between each button.
So, there are 4 equal spaces between the buttons.
Distance between each two consecutive buttons =[tex]\frac{15.25}{4}[/tex] =3.8125
So, distance between the top two buttons on his shirt is 3.8 inches.
what is the missing value
Answer:
Plug in what you are given for y then solve for x:
[tex]-2 + 2 = -3(x - 4)\\\\0 = -3(x - 4)\\\\0 = -3x + 12\\\\-12 = -3x\\\\4 = x[/tex]
The missing value would be 4.

There were 3 boys for every 4 girls in the group if there was 20 girls how many students went on the trip.
Answer:
35 students
Step-by-step explanation:
If there are 4 girls, then there are 3 boys
You will multiply both by 5 to get 20
So 3×5 is 15
20+15 = 35
Answer: 35 students
Explanation: Divide 4 into 20 to see how many sets of 4 girls there are. So there are 5 sets of four girls.
Five times three is 15.
In total (15 + 20), there are 35 students.

Where can we put parentheses in 45 – 22 +9 to make it equivalent to 14?
Choose 1 answer.
45 – (22 +9)
(45 – 22) +9
Answer:
45 – (22 + 9)

What is the equation of function g
Answer:
i needed points to ak a question
Step-by-step explanation:
Your eccentric Aunt Isabella sends money to each niece and nephew on his or
her birthday, She gives each child $10 on his or her first birthday. On each
birthday thereafter, you and your cousins get $20 more than on the birthday
before. How old will you be when you have received a total of $4,000 from
Aunt Isabella?
How old will you be when you have Received a total Of $4000 from aunt Isabell?
Answer:
20 years old
Step-by-step explanation:
Given
Base Amount = $10
Additional Amount = $20
Required
Determine the number of years where the total will accumulate to $4000
This question represents Sum of an AP series.
[tex]S_n = \frac{n}{2}(2a + (n - 1)d)[/tex]
Such that:
[tex]S_n = 4000[/tex]
[tex]a = 10[/tex]
[tex]d = 20[/tex]
Substitute these values in the above formula:
[tex]4000 = \frac{n}{2}(2 * 10 + (n - 1) * 20)[/tex]
[tex]4000 = \frac{n}{2}(20 + 20n - 20)[/tex]
[tex]4000 = \frac{n}{2}(20n)[/tex]
[tex]4000 = \frac{20n^2}{2}[/tex]
[tex]4000 = 10n^2[/tex]
Divide through by 10
[tex]400 = n^2[/tex]
Take square root of both sides
[tex]20 = n[/tex]
[tex]n = 20[/tex]
