If two angles are complementary and one angle measures 89, what is the measure of the other angle?

1 answer:

6 0

Complimentary means they add up to 90

x is the angle we're looking for

x + 89 = 90

Subtract 81

x = 90 - 89

x = 1

A 6 inch personal pizza has 650 calories, with 240 of those from fat. A 14 inch pizza is cut into 8 slices. Estimate the number

professor190 [17]

Answer:

Number of calories in one slice of a 14 inch pizza is 189.825. 

Step-by-step explanation:

Given that 6 inch pizza has 650 calories. 

Therefore 1 inch pizza has $\frac{650}{6}$ calories. 

14 inch pizza will have

$\frac{650}{6} \times 14=216.67 \times 14=1516.66 \ calories$

Given that the 14 inch pizza is divided into 8 slices.

Therefore each slice of the 14 inch pizza will have

 $\frac {1516.66}{8} =189.825 calories$

olga nikolaevna [1]

The probability that the combination starts with 2 is 1/3

<h3>Probability</h3>

Probability is the likelihood or chance that an event will occur.

Probability = expected/total outcome

The total outcome = 3! = 6

The expected outcome if the combination starts with 2 is given as 2! = 2

Pr(the combination starts with 2) = 2/6 = 1/3

Hence the probability that the combination starts with 2 is 1/3
