PLEASEEEE HELP!!! I really don’t understand math and I will Mark brainliest
lbvjy [14]

Answer:

1.5

Step-by-step explanation:

Because the triangle are similar, they possess a proportional relationship in which the one triangle's side length is dilated by a unknown factor (y) to make its corresponding counterpart. Using this knowledge we can make the following two equations

3y=7  & xy=x+2   y is the variable representing the dilation factor

y=7/3 find the value of y

x(7/3)=x+2 substitute the value y into the equation

7/3x =x+2 solve for x

4/3x =2

(3/4)(4/3x)=2(3/4) multiply by the reciprocal

x=1.5

A scale model of the Great Pyramid of Giza is being installed in a museum. The edges of the square base have lengths of 5.6 feet
IgorLugansk [536]

The answer to the question to <u>how many significant figures could the volume of the pyramid be reported</u> is B. 2 significant figures.

Since in multiplication, we cannot have more significant figures than the number with the least significant figures. So, the number of significant figures in our volume of the pyramid will be 2 since, the length of side of its square base measures 5.6 feet which is one significant figure less than that of its height which is 7.86 feet.

Since volume = area of base × height

volume = 5.6 × 5.6 × 7.86 ft³

So, the answer volume of the pyramid will have 2 significant figures.

The answer to the question to <u>how many significant figures could the volume of the pyramid be reported</u> is B. 2 significant figures.
