Answer:

120 yd2

Step-by-step explanation:

I assume you are solving for area.

The formula for a paralellogram (what it appears to be) is base times height.

The base in this equation is 10, and the height is 12. Multiplying this you get 120 yards squared.

For perimeter, you use pythagorean theorem to get the diagonal. $2\sqrt{61}$ . Then multiply 10 and $2\sqrt{61}$ by two, and then add them. $20+4\sqrt{61}$ .

liq [111]

Easy. You're finding unit rates for both Betty's and Shari's.

Betty's: Divide 2.00 and 5 to get 0.4 or $0.40

Shari's: Divide 2.30 and 6 to get .38 (Had to round) or $0.38

Conclusion: Shari's is the better buy, you'll be saving 2 cents!

Hope this helped!

What is the length of the unknown leg in the right triangle?

Rama09 [41]

Answer:

we will use Pythagorean's Theorem

$25^{2}=20^{2}+b^{2}\\\\ b=\sqrt{25^{2}-20^{2}}\\\\ b=\sqrt{625-400} =\sqrt{225}\\\\ b=15$

Therefore, the missing leg is 15 meters long.

Step-by-step explanation:

we will use pythagoras theorem

Given that,

One leg of the triangle is 20 meters long,

the hypothenuse is 25 meters long,

and the leg missing is called x.

we will use Pythagorean's Theorem

$25^{2}=20^{2}+b^{2}\\\\ b=\sqrt{25^{2}-20^{2}}\\\\ b=\sqrt{625-400} =\sqrt{225}\\\\ b=15$

Therefore, the missing leg is 15 meters long.

A bus makes a stop at 2:30, letting off 11 people and letting on 8. The bus makes another stop ten minutes later to let off 5 mo

Dafna11 [192]

Answer:

The actual number of passengers on the bus falling by 8 after the second stop

Step-by-step explanation:

Assume that the total passengers on the bus before 2:30 was x

At 2:30:

11 passengers got off and 8 got on.

So, the number of passengers

= x - 11 + 8

= x - 3

10 minutes later:

5 passengers got off the bus

So, the number of passengers

number of passengers = (x - 3) - 5

number of passengers = x - 8

now by comparing,

The actual number of passengers on the bus falling by 8 after the second stop
