One leg of a right triangular piece of land has a length of 24 yards. They hypotenuse has a length of 74 yards. The other leg has a length of 10x yards. What is the value of x?

Answers

Solutions

To solve this problem we have to use the Pythagorean theorem. You can only use the Pythagorean theorem in Right Triangles. The longest side of the triangle is called the "hypotenuse". C² is the longest side so it is the hypotenuse . To calculate c² we have to do α² + β² = c². 

Given 

One leg of a right triangular piece of land has a length of 24 yards. They hypotenuse has a length of 74 yards. The other leg has a length of 10x yards.

First leg (24 yards) would be α 

Second leg would be β

Hypotenuse (74 yards) would be c

Now we have points α β c.  

a² (24) + β² ( x ) = c² (74) 

Calculations 

c² = α² + β²

74² = 24²+ β² 

5476 = 576 + β² 

5476 - 576 = β²
 
4900 = β² 

→√4900 
 
β = 70 yards 

70 = 10x 

x = 70÷10 = 7 yards  

The second leg = 7 yards

Anybody knows the answer?

Answers

The top and bottom faces are 3 inches by 3 inches.

Area = 3 in. * 3 in. * 2 = 18 in.^2

The front, back, right, and left faces are 3 in. by 6 in.

Area = 3 in. * 6 in. * 4 = 72 in.^2

Total surface area = 18 in.^2 + 72 in.^2 = 90 in.^2

Answer: B. 90 square inches

Need Help!!!Rae sold 765 shirts in a week. Mandy sold 8900. How many less did Rae sell than Mandy?
Need 2 ways!!! 2 answers!!!!!!!!! Please! ASAP!

Answers

Rae sold: 765 shirts in a week.
Mandy sold: 8,900 shirts in a week.

Key word: Less
We need to subtract. 

8900 - 765 = 8,135

Rae sold 8,135 shirts LESS than Mandy.

OR Mandy sold 8,135 MORE shirts than Rae. 
8900 - 765 = 8135
So Rae sold 8135 LESS shirts and....
Mandy sold 8135 MORE shirts!

Which pair of ratios is proportional? A. 5/7 and 25/35 B. 6/9 and 18/26 C. 9/18 and 16/36 D. 35/120 and 75/240

Answers

The answer is A bcause 5×5/7×5=25/35.
Its A:(5)/(7)=(25)/(35)
because (5*5)/(7*5)=(25)/(35)
the others do not have a common number multiplied in the numerator and denominator. 
Note: If the numerator and Denominator are multiplied by the same number, it is proportional.
In this example, it was multiplied by 5
