Answer:

28 meters

Step-by-step explanation:

<u><em>The question in English is</em></u>

On a 32-meter roll of fabric, it cuts an eighth of the total. How many meters of fabric are left in a roll?

step 1

we know that

To find out how many meters of fabric were cut, multiply the total meters by the fraction that was cut

$32(\frac{1}{8})=4\ m$

step 2

To find out how many meters of fabric are left, subtract the meters of fabric that were cut from the total meters of fabric

$32-4=28\ m$

What is the measure of angle A?

I am Lyosha [343]

First you have to find the angle B (check attachment)

$B = 180^{\circ} - 137^{\circ} = 43^{\circ}\\$

Then you can find the last angle inside the triangle, which I'll call C

$C = 180^{\circ} - 102^{\circ} - 43^{\circ} = 35^{\circ}$

Now you can find angle A

$A = 180^{\circ} - C = 180^{\circ} - 35^{\circ} = 145^{\circ}$

What is a coefficient ?

Ahat [919]

A coefficient is a number that is attached to a term.

For example:

3x² - 5x + 6 = 0

The coefficient of x² is 3.

The coefficient of x = -5.

Hope this explains it.

Answer:

The triangular prism is a better deal because you get 204 in³ for the same price you would pay for 128 in³ with a trapezoidal prism.

Step-by-step explanation:

The trapezoidal prism has volume 32*4=128 cubic inches. The triangular prism has volume 34*6=204 inches. Since the triangular prism is more voluminous, it is the better deal. Hope this helps!

I got (-6.28, -0.76).

Step 1.) Write out the problems
-2x=8-6y
-15x=21-6y

Step 2.) Pick a problem and solve for X
-2x=8-6y = x=-4-3y

Step 3.) Plug in the x
(-15)(-4-3y)= 21-6y
60 + 45y= 21-6y

Step 4.) Solve for y
y=-0.76

Step 5.) Plug in the y value into one of the equations
-2x= 8- 6(-0.76)
-2x= 8 + 4.56
x= -6.28

Step 6.) Check your answers
-2(-6.28)=8-6(-0.76)
12.56=12.56

Step 7.) Write it out
(-6.28,-0.76)
