I will say 1 block is 1 something okay cause I don’t have a key mini has an area of 2 (2x2=4/2=2) And the giant has an area of 32 (8x8=64/2=32) I don’t know if the small one became big or the big one became small so if the small to big is 16 big to small is 0.0625 or the numbers the other way around

Answer:

Area of left triangle = 2 * 2 / 2 = 2

Area of triangle on the right = 8 * 8 / 2 =32

32 / 2 = 16

Therefore the triangle on the right has 16 times the area than the triangle on the left.

Last summer, Marrero was at Newgrange, a stone mound in Ireland that has a diameter of 250 feet. He found a walkway 62 feet long

timofeeve [1]

Answer:

108 ft

Step-by-step explanation:

The line connecting the center with the end of the walkway is radius and is the hypotenuse of the right triangle.

Horizontal leg is the distance x.

<u>Vertical leg has the length:</u>

(250)/2 - 62 = 63 ft

<u>Using Pythagorean theorem to find the length of x:</u>

x² = (250/2)² - 63²
x² = 125² - 63²
x² = 11656
x = √11656
x = 107.96 ≈ 108

Answer:

n=42 adult men

Step-by-step explanation:

-The minimum sample size to get a desired margin of error, E is calculated using the formula:

$n\geq( \frac{z\sigma}{E})^2$

-Given that $\sigma=7.5, \ \ E=3\ , \ z_{0.005}=2.58$ , we can substitute to solve for n in the above formula:

$n\geq (\frac{z\sigma}{E})^2\\\\\therefore n=(\frac{z_{\alpha/2}\sigma}{E})^2\\\\=(\frac{2.58\times7.5}{3})^2\\\\=41.6025\approx42$

Hence, the desired minimum sample size, n is 42 adult men.

For the rectangle shown, which equation can be used to find the value of x?

sweet-ann [11.9K]

Answer:

The 4th one: 3^2 + 13^2 = x^2

Step-by-step explanation:

The <u>pythagorean theorem</u> is a^2 + b^2 = c^2. In this case 3 is a, 13 is b, and x is c.
