Answer 1

Given:

One of the legs of a right triangle is 9 cm.

The area of the triangle is 225 cm².

To find:

The length of the other leg.

Solution:

The area of a triangle is

[tex]Area=\dfrac{1}{2}\times Base\times Height[/tex]

The area of a right triangle is

[tex]Area=\dfrac{1}{2}\times (leg_1)\times (leg_2)[/tex]

Let x be the length of other leg.

[tex]225=\dfrac{1}{2}\times (9)\times (x)[/tex]

[tex]2\times 225=9x[/tex]

[tex]\dfrac{450}{9}=x[/tex]

[tex]50=x[/tex]

Therefore, the length of the other leg is 50 cm.

13) A Super Bowl Party Sub was cut into 3 equal pieces that were x inches long. Kevin took
6 inches of the sub for himself. There was still 30 inches of the sub when the game started.
How many inches was each of the pieces?

Answers

Answer:

12 inches

Step-by-step explanation:

now i am assuming kevin took 6 inches of the sub before the game because it says "there was still 30 inches of the sub when the game started". In that case, add 6 and 30 to get 36. Because the sub was cut into 3 equal pieces, divide 36 by 3 and get 12 inches as your final answer.

What are the 2 answers?

Answers

Answer:

7060

Step-by-step explanation:

by solving inequality :

x-3 <70x < 73

so the value of x should be less than 73.

so required values are 70 and 60

70 and 60 are the correct answers. If you take 70 and subtract 3 you get 67, which is less than 70. If you take 60 and subtract 3 you have 57, which is less thna 70. Basically any number that is 72 or less would be a coorect answer

the area of a certain desert is nine times the area of another desert. if the sum of their areas is 30,000,000 sq miles. find the area of each. ​

Answers

So the sum of both deserts is 30000000 and one is 9 times more than the other, it’s a 1:9 ratio. 9+1 is ten and 30000000/10 is 3,000,000. That’s the area of the smaller desert. You multiply 3 million by 9 and get 27,000,000 sq miles for the larger desert. Hope that makes some sense! :)

Claire is building a dollhouse where 11 inch on the plans is equivalent to 55 inches on the actual dollhouse.



If the actual dollhouse is to be 60 inches tall, what will the height be on the plans?

Answers

55:11 is the ratio of actual inches to inches on the plan.

55/5=11, so each inch on the plan is equal to 5 inches in actuality.

60/5=12, so the height on the plans would be 12 inches.
