Answer:

[tex] y = \frac{1}{4}x + 1 [/tex]

Step-by-step explanation:

Line is passing through the points (0, 1) & (4, 2)

Slope of line = (2 - 1)/(4 - 0) = 1/4

y-intercept (b) = 1

Equation of line in slope-intercept form is given as:

[tex]y = mx + b \\ \\ y = \frac{1}{4}x + 1 [/tex]

Answer:

[tex]y = \frac{1}{4}x + 1[/tex]

Step-by-step explanation:

Slope intercept form allows one to write an equation for a line from only the y-intercept and the slope, so we need to identify those two things.

The slope is simply [tex]\frac{y_2 - y_1}{x_2-x_1}[/tex]=>[tex]\frac{2-1}{4-0}[/tex]=> 1/4

The slope intercept is the y value when x = 0, and since we have the point (0,1), the y-intercept must be 1

The equation is: y = mx + b where m is the slope and b is the intercept so the final equation is:

[tex]y = \frac{1}{4}x + 1[/tex]

The age of Mark’s dad is 4 less than twice Mark’s age. The sum of their ages is 95. Find their ages.

Answers

d = 2m - 4 (Dad's age is 4 less than twice Mark's)
m + d = 95 (their ages total 95)

We have a value for d, so plug it in:
m + 2m - 4 = 95
Simplify:
3m - 4 = 95
Add 4 to both sides:
3m = 99
Divide by 3:
m = 33

A cylindrical drinking glass has a base radius of 3.2 centimeters and a height of 14.0 centimeters. Given that 1 cubic centimeter is equivalent to
1 milliliter, how many milliliters of water does the glass hold when it is full? Round your answer to the nearest millimeter.
ml (Only enter the number, no words.)

Answers

Answer:

450 ml.

Step-by-step explanation:

Volume of a cylinder:

The volume of a cylinder is given by:

[tex]V = \pi r^2h[/tex]

In which r is the radius and h is the height.

A cylindrical drinking glass has a base radius of 3.2 centimeters and a height of 14.0 centimeters.

This means that [tex]r = 3.2, h = 14[/tex]

How many milliliters of water does the glass hold when it is full?

Radius and height are measured in centimers, so the volume will be in cubic centimeters, which is the same as milliliter. So

[tex]V = \pi(3.2)^2*14 = 450.3[/tex]

Rounding to the nearest millimeter, the answer is 450 ml.

Update: answer is 0,5

Answers

Answer:

x = 0 , 5

Step-by-step explanation:

[tex]\frac{2x}{x-3}=\frac{3x}{x-2}[/tex]

Cross multiply,

2x* ( x - 2) = 3x *(x - 3)

2x*x - 2*2x  = x*3x - 3*3x

2x² - 4x   = 3x² - 9x

subtract 2x² from both sides

-4x = 3x² - 2x² - 9x           {Combine like terms}

-4x = x² - 9x

Add 9x to both sides

-4x+ 9x = x²

x² = 5x

x² - 5x = 0

x(x - 5) = 0

x = 0  ; x - 5 = 0

30 × 1/5 = 151/5

151/5 /40 = x / 60

What would her total in dollars and cents be, after the discount and
before tax, if the total cost of all the items she wants to buy is $32.40?

Answers

Answer:

The price of the items before the discount was $36.

Step-by-step explanation:

Since Emma has a loyalty card good for a 10% discount at her local pharmacy, to determine what her total in dollars and cents be, after the discount and before tax, if the total cost of all the items she wants to buy is $ 32.40, the following calculation must be made:

100 - 10 = 90

90 = 32.40

100 = X

100 x 32.40 / 90 = X

3240/90 = X

36 = X

Therefore, the price of the items before the discount was $ 36.

What is the area of this figure?

Answers

Answer:

161

Step-by-step explanation:

8*14+13*3+(5*4)/2

112+39+10 = 161

Answer:

161 [tex]m^2[/tex]

Step-by-step explanation:

Divide the given figure up into smaller pieces, calculate the area of each of the smaller pieces and add up the area to find the total area of the figure. One can partition the figure into two rectangles with dimensions (14 by 8) and (13 by 3) respectively, and a (4 by 5) triangle.

The formula for the area of a rectangle is (base * height), substitute in the given values,

14 * 8 = 112

13 * 3 = 39

The formula for the area of a triangle is ([tex]\frac{(base)*(height)}{2}[/tex]), substitute in the given values and solve,

[tex]\frac{(5)*(4)}{2}[/tex] = 10

Now add up all the values to find the total area of the figure,

112 + 39 + 10 = 161

Find y.
Round to the nearest tenth:
у
270
350 ft
y = [? ]ft

Answers

Answer:

178.3

Step-by-step explanation:

Hello There!

We can find the value of y using trigonometry

These are the trigonometric ratios

Remember SOHCAHTOA

Sine = Opposite over Hypotenuse

Cosine = Adjacent over Hypotenuse

Tangent = Opposite over Adjacent

For the angle that has a measure of 27 degrees

we are given its adjacent angle and we need to find its opposite angle (y)

Adjacent and Opposite sides corresponds with the trigonometric ratio Tangent so we are going to use the trigonometric ratio tan to solve for y

Now we set up an equation (remember tangent = opposite over adjacent)

[tex]tan(27)=\frac{y}{350}[/tex]

Now that we have created an equation we want to solve for y

What we want to do is isolate the variable using inverse operations

So basically we want to get rid of the 350

The opposite of division is multiplication so we multiply each side by 350 to get rid of it

[tex]tan(27)*350=350tan(27)\\\frac{y}{350} *350=y\\y=350tan(27)\\350tan(27)=178.3339073\\[/tex]

so we can conclude that y = 178.3339073

finally we want to round to the nearest tenth and we get that the answer is 178.3
