Answer: x = 34°


Explanation:


As per definition, complementary angles add up 90°.


In the figure you see angle A measures x + 22° and angle B measures x.


Therefore, according to the definition, you can set this equation:

       

             x + 22° + x = 90°


Solve for x:


  • start: x + 22 + x = 90
  • combine like terms: 2x + 22 = 90
  • subraction property: 2x = 90 - 22
  • do the operation: 2x = 68
  • division propery: x = 68/2
  • do the operation: x = 34

Answer: x = 34°

Find the missing number: 8.4(1.5 + 2.3) = 12.6 +
Fynjy0 [20]

Answer:

19.32

Step-by-step explanation:

One way to find the missing number is to get the value of the left side of the equation first.

8.4(1.5 + 2.3) = 31.92

Now we need to take that value and subtract it to the value on the right side of the equation.

31.92 - 12.6 = 19.32

So we have:

8.4(1.5 + 2.3) = 12.6 + 19.32

31.92 = 31.92

What is the exact volume of a sphere with a diameter of 36 in.?
Contact [7]
The volume of a sphere:
V=\frac{4}{3} \pi r^3
r - the radius

The diameter is twice the radius.
d=36 \ in \\
r=\frac{36}{2} \ in = 18 \ in \\ \\
V=\frac{4}{3} \pi \times 18^3=\frac{4}{3}\pi \times 5832=\frac{23328}{3} \pi=7776\pi \ [in^3]

The exact volume of the sphere is 7776π in³.

Let X be the random variable denoting the number of successful throws.

Here X~ Binomial Distribution with n = 5 and p = 0.80.

the probability of her missing 3 (or more) free throws out of 5

= P ( X ≤ 2)

= P (X= 0) + P(X= 1) + P(X= 2)

=0.00032 + 0.0064 + 0.0512

Diego is building a patio deck. The length of the deck is (x + 8) feet. The width of the deck is (x + 3) feet. What is the simpl
antoniya [11.8K]

Answer:

(4x + 22) feet

Step-by-step explanation:

Diego is building a patio deck. The length of the deck is (x + 8) feet. The width of the deck is (x + 3) feet. What is the simplest form expression for the perimeter of the deck?

A patio deck = Rectangular in shape

Hence:

The formula for the Perimeter of a rectangle = 2L + 2W

Where

L = Length

W = Width

The length of the deck is (x + 8) feet. The width of the deck is (x + 3) feet.

The perimeter of the deck =

2(x + 8)feet + 2(x + 3)feet

= (2x + 16) feet +( 2x + 6)feet

= (2x + 2x + 16 + 6) feet

= (4x + 22) feet

Therefore, the perimeter of the deck = (4x + 22) feet
