Akiko is making a pizza. The radius of the pizza is 19 inches. What is the circumference of the pizza (use 3.14 for pi and round

Answer:

≈119.3

Step-by-step explanation:

The area for circumference is as follows:

C = 2\pi r\\or\\C = d\pi

The above equations mean the same thing, because the diameter is just 2 times the radius.

Anyhow, we insert this value into the equation...

C = 2\pi(19)\\C = 38(3.14)\\C = 119.32\\

This rounds to:

≈119.3

Yuto and Riko went for a bike ride on the same path. When Riko left their house, Yuto was 5.25 miles along the path. If Yuto’s a
Nimfa-mama [501]

Answer:

Step-by-step explanation:

When Riko left his house, Yuto was 5.25 miles along the path.

Average speed of Riko = 0.35 miles per minute

Average speed of Yuto = 0.25 miles per minute

First we will calculate the time in which Riko will catch Yuto on the track.

Relative velocity of Riko as compared to Yuto will be = velocity of Riko - velocity of Yuto

= 0.35 - 0.25

= 0.10 miles per minute

Now we this relative velocity tells that Riko is moving and Yuto is in static position.

By the formula,

Average speed = \frac{Distance}{Time}

0.10 = \frac{5.25}{t}

t = \frac{5.25}{0.1}

t = 52.5 minutes

Now we know that Rico will catch Yuto in 52.5 minutes. Before this time he will be behind Yuto.

So duration of time in which Rico is behind Yuto will be 0 ≤ t ≤ 52.5

Here time can not be less than zero because time can not be with negative notation. It will always start from 0.

The quotient of two less than a number and five is eight
postnew [5]

Answer:

The number is 42.

Step-by-step explanation:

Let x be the unknown number.

"two less than a number" is x - 2

Quotient means the result of a division.

(x - 2)/5 = 8

Multiply both sides by 5.

x - 2 = 40

Add 2 to both sides.

x = 42

Answer: The number is 42.

Check.

Start with 42. 2 less than 42 is 40. The quotient of 40 and 5 is 40/5 which is 8. The answer is correct.

A fair spinner has 9 equal sections: 2 red, 3 blue and 4 green.
Alex17521 [72]

Answer:

The Probability of not getting two consecutive reds is 0.9506

Step-by-step explanation:

Number of sections = 9

Number of red sections = 2

Number of blue sections = 3

Number of green sections = 4

Probability of getting two consecutive reds = \frac{2}{9} \times \frac{2}{9}=\frac{4}{81}

So,The Probability of not getting two consecutive reds =1- \frac{4}{81}=\frac{77}{81}=0.9506

Hence The Probability of not getting two consecutive reds is 0.9506
