The combined perimeter of the rectangle and triangle is 63 inches. The model shows the dimensions of the rectangle. What is the

katrin2010 [14]

*See diagram in the attachment

Answer:

27 inches

Step-by-step explanation:

Combined perimeter = perimeter of rectangle + perimeter of triangle = 63 inches

Perimeter of rectangle = 2(L + W)

L = 11 in.

W = 7 in.

Perimeter of rectangle = 2(11 + 7) = 36 in.

Let perimeter of the triangle be represented by x

Therefore:

36 + x = 63

Subtract 36 from each side

x = 63 - 36

x = 27

Perimeter of triangle = 27 inches

Ami has a mass of 72 kg.

il63 [147K]

${\huge{\underline{\sf{Answer}}}}$

<h3>» Ami's mass is $\sf \frac{2}{3}$ the mass of Raphael.</h3>

Solution:

Given that

Ami's mass is 72 kg and
Raphael's mass is 108 kg.

To write Ami’s mass as a fraction of Raphael's mass, we divide Ami's mass by Raphael's mass. So it is now $\sf \frac{72}{108}$ .

However, there the fraction is not yet in its simplest form, so we have to extract common factors from both the numerator and the denominator:

$\sf \frac{36 \times 2}{36 \times 3}$

= ${\boxed{\sf \frac{2}{ 3}}}$

Therefore, Ami's mass is $\sf \frac{2}{3}$ the mass of Raphael.

I’m stuck on this, can someone explain please? Thanks!

ololo11 [35]

first off, I'd like to point out that for the 5th test, he has 96, and that's +6 above 90, and therefore it should be 6.

if all the above/below numbers, summed up yield 0, that simply means the average is an even 90 on average for all 6 tests, if they yield above 0, is above on the average, and if it's below 0, a negative value, he needs to do more work.

-7+4-11+7+6-3 = -4.

you can think of it this way, if he had 90 on all 6 tests, the above/below row will show 0, 0, 0, 0, 0, 0. If any of the tests was above 90, that row will yield a sum more than 0, and if any of the tests were below, that sum will be a negative value.
