Henry packed some apples in a box. The total mass of the box and the apples was 16 240 g. He packed some strawberries in a simil

icang [17]

Step-by-step explanation:

x = mass of apples

y = mass of strawberries

z = mass of the box

x = 3y

x + z = 16240

y + z = 6350

let's subtract the second from the first equation

x + z = 16240

- y + z = 6350

-----------------------

x - y + 0 = 9890

using the first identity in that result gives us

3y - y = 9890

2y = 9890

y = 4,945 g

x = 3y = 3×4945 = 14,835 g = the mass of the apples

Given the isosceles trapezoid below, find AG.<br> Show all the work

Dmitry [639]

We know the width of the rectangle in the middle of the trapezoid is 24 (from the top of the image), so we can subtract that from the bottom width of the trapezoid to get the combined length of the bottom of both triangles.

$40 - 24 = 16$

Since this is an isosceles trapezoid, both triangle bases are the same length, so we can cut this value in half to get the length of $GT$ and $EF$

$\frac{16}{2} = 8$

Finally, we can use the Pythagorean Theorem to find the length of $AG$ :

$AG^{2} + GT^{2} = AT^{2}$

$AG^{2} + 8^{2} = 10^{2}$

$AG^{2} + 64 = 100$

$AG^{2} = 36$

$AG = 6$
