Answer:

D. y=4x

Step-by-step explanation:

It asks for a proportional relationship between x and y

And is the only answer

because

When x and y is 1 the answer is

4/1

And when x and y is 2 the answer is

8/2

If you divide both of them are still 4

And this will always be the result no matter how many times you do it

like if you put it as 150

150 times 4 is 600/150

600 divided by 150 is 4

Hope this helps!

The measure of two complementary angles have a ratio of 3:2. What is the measure of the larger angle?

azamat

Answer:

54 degrees

Step-by-step explanation:

Complementary angles add to 90 degrees

3:2

Multiply each by x

3x:2x

Add the angles together and set equal to 90

3x+2x = 90

Combine like terms

5x= 90

Divide each side by 5

5x/5 = 90/x

x =18

The angles are 3x = 3(18) =54

and 2x = 2(18) = 36

Can someone help me with this question ? Show steps please

Answer:

B) $\boxed{A_T=108\;in^2}$

Step-by-step explanation:

That is a triangular prism and thus, it has two bases that are triangles, in this case, right triangles, whose hypotenuse is 5 in. long and one of its legs is 4 in. and the other one, 3 in.

The first step is to find the area of both bases like this:

$A_B=2\left(\dfrac{b\cdot h}{2}\right)=b\cdot h=4\cdot 3\\\\ \boxed{A_B=12\;in^2}$

The second step is to get the lateral area, which is compound of three rectangles, hence the process is the following:

$A_L=b_1\cdot h_1+b_2\cdot h_2+b_3\cdot h_3\\A_L=8\cdot3+8\cdot4+8\cdot5\\A_L=24+32+40\\\boxed{A_L=96\;in^2}$

Finally, we sum both of the areas found to calculate the total area.

$A_T=A_B+A_L\\A_T=12+96\\\boxed{A_T=108\;in^2}$

So, the answer is option B).

If the pressure inside a rubber balloon is 1500 mmHg, what is this pressure in pounds-force per square inch (psi)? Answer: 29.0

madreJ [45]

Answer:

Step-by-step explanation:

You already have the answer.

1 [at] = 760 [mmHg]

1 [at] = 14,7 [psi]

1500 [mmHg] * 1 [at] / 760 [mmHg] * 14,7 [psi] / 1 [at] = 29.0 [psi]
