aylor and Natsumi are making block towers out of large and small blocks. They are stacking the blocks on top of each other in a

frozen [14]

Answer:

The height of a large block is of 12.1 inches and of a small block is of 7.7 inches.

Step-by-step explanation:

This question is solved using a system of equations.

I am going to say that:

x i the height of a large block.

y is the height of a small block.

Taylor uses 4 large blocks and 2 small blocks to make a tower 63.8 inches tall.

This means that:

$4x + 2y = 63.8$

Simplifying by 2:

$2x + y = 31.9$

$y = 31.9 - 2x$

Natsumi uses 9 large blocks and 4 small blocks to make a tower 139.8 inches tall.

This means that:

$9x + 4y = 139.8$

Since $y = 31.9 - 2x$

$9x + 4(31.9 - 2x) = 139.8$

$9x + 127.6 - 8x = 139.8$

$x = 12.1$

$y = 31.9 - 2x = 31.9 - 2(12.1) = 7.7$

The height of a large block is of 12.1 inches and of a small block is of 7.7 inches.

What is the value of x? A.2 B.3 C.6 D.7

Ira Lisetskai [31]

Answer:

Step-by-step explanation:

Given 2 secants from a point outside the circle.

Then the product of the external part and the entire secant of one secant is equal to the product of the external part and the entire secant of the other secant, that is

(x + 1)(x + 1 + 11) = (x + 4)(x + 4 + 1)

(x + 1)(x + 12) = (x + 4)(x + 5) ← expand both sides

x² + 13x + 12 = x² + 9x + 20 ← subtract x² + 9x from both sides

4x + 12 = 20 ( subtract 12 from both sides )

4x = 8 ( divide both sides by 4 )

x = 2 → A

The area of a trampoline is 49 pi sqared. What's the diameter of the trampoline?

Flauer [41]

Answer:

The diameter is 14

Step-by-step explanation:

The area of a circle is given by

A = pi r^2

We know the area is 49 pi

49 pi = pi r^2

Divide each side by pi

49 pi/ pi = pi r^2/pi

49 = r^2

Take the square root of each side

sqrt(49) = sqrt(r^2)

7 =r

We want the diameter

d = 2r

d = 2*7

d = 14
