Answer:

21 : 24

Step-by-step explanation:

Sum the parts of the ratio, 7 + 8 = 15 parts

divide 45 by 15 to find one part of the ratio

45 ÷ 15 = 3 ← value of 1 part of ratio, thus

7 parts = 7 × 3 = 21

8 parts = 8 × 3 = 24

45 divided in the ratio 7 : 8 is 21 : 24

sergey [27]

Answer:

The winner completed the race in 96 hours and 52 minutes.

Step-by-step explanation:

Given:

Distance of the cycling race = 2292 miles

Average speed of the winner = 23.66\  mph

We need to find time required by winner to complete the race.

Solution:

Now we know that;

Time required can be calculated by dividing Total Distance from the Average speed.

framing in equation form we get;

time required by winner to complete the race = \frac{2292}{23.66} = 96.87\ hrs

Now converting 0.87\ hrs into minutes we get;

0.87\times 60= 52.2\approx 52\ mins

Hence the winner completed the race in 96 hours and 52 minutes.

adelina 88 [10]

Answer:

The answer to your question is Circumference = 81.64 ft

Step-by-step explanation:

Data

Area of a circle = 530.66 ft²

Circumference = ?

π = 3.14

Process

1.- Calculate the radius of the circle

Area = πr²

-Solve for r²

  r² = Area / π

-Substitution

  r² = 530.66 / 3.14

-Simplification

  r² = 169

-result

  r = 13 ft

2.- Calculate the Circumference      

Circumference = 2πr

-Substitution

Circumference = 2(3.14)(13)

-Result

Circumference = 81.64 ft
