Area of a triangle = \frac{1}{2} · base x height
                     180 = \frac{1}{2} · base x 40
                     180 = 20 · base
                        9  = base

Pythagorean Theorem:
base² + height² = hypotenuse²
  9²     +    40²    = hypotenuse²
 81     +   1600   = hypotenuse²
      1681            = hypotenuse²
     √1681           = √hypotenuse²
         41            = hypotenuse

Answer: the length of the hypotenuse is 41 m

Is (-3, 2) a solution of -4r - 10y< - 9?
Blizzard [7]

Answer:

<em>The point (-3,2) is not a solution of the inequality</em>

Step-by-step explanation:

<u>Inequality</u>

Inequalities relate the left and the right side of an expression with an operator other than the equal sign.

The inequality given in the question is

-4r - 10y< - 9

There are many combinations of r and y that make inequality be true. For example, for r=1 and y=1

-4(1) - 10(1)< - 9

-14< - 9

This relation is true since -14 is less than -9.

Also, there are many combinations that make the given inequality be false.

For example, for r=2 and y=-1

-4(2) - 10(-1)< - 9

-8+10

2

This inequality is false.

Let's test the point (-3,2)

-4(-3) - 10(2)< - 9

12-10

2

Which is false, thus the point (-3,2) is not a solution of the inequality

BlackZzzverrR [31]
3:5 = 64cm
3x+5x= 64
8x=64
x=8

Therefore,

3x=8×3
=24

5x=8×5
=40

3x+5x=64cm

36, 27, <br> 81<br> 4<br> Find the 10th term.
zaharov [31]

a_{10} = \frac{177147}{65536} is solution of arithmetic progression (AP).

What is arithmetic progression (AP)  in math?

  • The difference between any two consecutive numbers in an arithmetic progression (AP) is always a fixed amount.
  • The AP cost per invoice is calculated by dividing the total number of invoices paid over a certain time period by all the expenditures incurred to pay those invoices over that same time period.
  • An accurate assessment of a company's AP efficiency can be made using this metric in conjunction with other accounts payable measures.

Write the general term through the pattern a_{n} = 36( \frac{3}{4} )^{n-1}

Substitute and calculate a_{10} = \frac{177147}{65536}

A square parking lot has an area of 12,996 square yards. a. What is the length of one side of the parking lot? b. How many yards
jenyasd209 [6]

Answer:

114 yards

456 yards

Step-by-step explanation:

Given that:

Area of square parking lot = 12,996 square yards

The lenght of one side of the parking lot :

Area of a square = a² ; a = side length

Hence ;

12996 = a²

√12996 = a

114 = a

Hence, length of one side = 114 yards

Yards of fence needed to enclose parking lot :

Perimeter of a square = 4a ; a = side length

Perimeter = 4(114)

Perimeter = 456 yards
