Answer:

11 minutes and 15 seconds (11.25 minutes/ 11 and 1/4)

Step-by-step explanation:

create the corresponding ratio by dividing 200 by 15, 200 calories per 15 minutes. Which equates to 40 calories every three minutes which means 40/3 or 13 1/3 calories every minute. You can verify this by multiplying 15 and 40/3 to get 200 again.

The last step is to divide the calories burned by the corresponding ratio (40/3)

150/(40/3) = 11.25

and .25 or 1/4 of 60 seconds(in a minute) is 15 since 60/4 = 15.

Voting age

Levart [38]

Answer:

$\frac{17}{64}\approx 0.27$

Step-by-step explanation:

We have been given a table to voters and their ages. We are asked to find the probability that a voter is younger than 45.

Voting age Voters

17-29 9

30-44 8

45-64 32

65+ 15

We can see from our given table that age of 17 (9+8) voters is between 17 to 44 years.

To find the probability that a voter is younger than 45, we will divide 17 by total number of voters.

$\text{Total voters}=9+8+32+15=64$

$\text{Probability that a voter is younger than 45}=\frac{17}{64}$

$\text{Probability that a voter is younger than 45}=0.265625$

$\text{Probability that a voter is younger than 45}\approx 0.27$

Therefore, the probability that a voter is younger than 45 is 0.27.

What Two pairs of fractions are shown. Which symbol correctly compares 2/3 2/4 each pair of fractions?

VikaD [51]

Answer:

Greater than symbol.

2/3 > 2/4

Step-by-step explanation:

We have two fractions, 2/3 and 2/4

We then go back to the inequality part of mathematics where we have symbols such as greater than (>), less than (<), and equal to (=).

Of the three inequality symbols, we look and pick at the one that represents best, the fractions we were given.

2/3 and 2/4

With 2/3 being greater than 2/4.

2/3 = 0.67

2/4 = 0.50

Succinctly, 2/3 > 2/4.

If two trucks leave a given city on highways making an angle of 132 degrees with one another, traveling at 45 and 55 miles per h

Law Incorporation [45]

Answer:

183 miles to the nearest mile.

Step-by-step explanation:

Distance =Speed X Time

Distance of Truck B from point A=45 X2 =90 miles

Distance of Truck C from point A=55 X2 =110 miles

Angles between them, BAC=132°

We want to find the Distance BC denoted by a between the trucks.

Using Cosine Rule,

a²=b²+c²-2bcCos A

=90²+110²-(2X90X110XCos132°)

=33448.79

a=√33448.79

BC=182.89 miles

The distance between the trucks is 183 miles to the nearest mile.
