An older person is 7 years older than five times the age of a younger person. The sum of their ages is 37. Find their ages.

Answer:

A-B

Step-by-step explanation:

It doesn't say A=B... But just that A is a subset of B.

Anyways, why not try an example to help reveal the answer.

Let the universe set, U, be U={1,2,3,4,5,6}.

Let B={1,2,3,4} and A={1,3,5}

First choice would become A'={2,4,6}

Second choice would become B'={5,6}

Third choice would become A-B={5}

Fourth choice is just { }

B'-A'={5}

The only choice matching is A-B

Answer:

height of tree is 27 ft

Step-by-step explanation:

The corresponding parts of the problem are in proportion

let h be the height of the tree , then

[tex]\frac{6}{h}[/tex] = [tex]\frac{7}{31.5}[/tex] ( cross- multiply )

7h = 189 ( divide both sides by 7 )

h = 27

Height of tree is 27 feet

Answer:

C. 12/15

Step-by-step explanation:

2/3, 6/9, and 18/27 all simplify to 2/3. 12/15 does not.

Answer:

C. 12/15

Step-by-step explanation:

As it is mentioned above, the below text is the explanation, if you were here for the answer, it is above.

The question is asking which ratio is not equivalent. To simplify a ratio, divide all of the numbers in the ratio by the same number until they cannot be divided anymore.

So when we look at A. we see that you can not simplify 2/3 anymore. Hence:

A (simplified version): 2/3

When we look at B. we see that the ratio, or fraction, is 6/9. The numerator, or the top number, is 6, while the denominator (the number on the bottom), is 9. The GCF (The greatest common factor, or GCF, is a term used to describe the biggest number that can divide evenly into two or more numbers. Sometimes, this is also referred to as the greatest common divisor, GCD, or highest common factor, or HCF. A factor is a smaller number that can divide evenly into that number) of 6 and 9 is 3. So we divide the numerator and the denominator (both) by 3 to get to 2/3. Hence:

B (simplified version): 2/3

Now, when we look at C. we see that the ratio is 12/15. What is the GCF of 12/15? The GCF is 3. So we divide the numerator and the denominator by 3 to get:

C (simplified version): 4/5

Moving on to D. Let's make it quick. The ratio is 18/27. The GCF is 9. So we divide the numerator and the denominator by 9 to get::

D (simplified version): 2/3

If:

A (simplified version): 2/3

B (simplified version): 2/3

D (simplified version): 2/3

The one fraction that is not equivalent? I'll let you figure that out for yourself!

Step-by-step explanation:

1/2(10*7)*13

35*13=455

Answer:

a) 35/40, 36/40

b) 4/8, 6/8, 6/8

Step-by-step explanation:

In order to convert into like fractions, we must find a common denominator for both.

This just means finding the LCM of the existing denominators.

To find the LCM, list the prime factorization of each number, and multiply each factor together the maximum amount of times it appears in one factor.

Then figure out what you need to multiply the existing denominator by to get the common denominator, and multiply that number to the numerator as well.

Note that multiplying a fraction by x/x won't change the value because x/x is equal to 1.

If this sounds confusing- don't worry- it'll become more clear in the work below.

a) 7/8 and 9/10

Start by finding the LCM of 8 and 10

Prime factorization:

8- 2*2*2

10- 2*5

Multiple: 2*2*2*2*5

However, 2 appears in 10 once and 8 three times.

So we can cross out one "2" since the maximum amount of times it appears is three times, not four.

Hence the LCM is 2*2*2*5=40

40 will be the common denominator.

To get to 40 from 8, you need to multiply it by 5.

So we can do:

7/8*5/5=35/40

Repeat with the second fraction.

To get to 40 from 10, you need to multiply it by 4.

So we can do:

9/10*4/4=36/40

36/40>35/40

Therefore, the ascending order would be

35/40, 36/40 or 7/8, 9/10

b) 1/2, 3/4, 6,8

Start by finding the LCM of 2, 4 and 8.

Prime Factorization:

2: 2

4: 2*2

8: 2*2*2

Since 2 appears a maximum of 3 times in one number the LCM is:

2*2*2=8

So our common denominator will be 8.

To get to 8 from 2, you need to multiply it by 4.

1/2*4/4=4/8

To get to 8 from 4, you need to multiply it by 2.

3/4*2/2=6/8

The last fraction is already good.

6/8

Hence, the ascending order would be:

4/8, 6/8, 6/8 or 1/2, 3/4, 6/8

Hope that helps! Let me know if you have any questions :)

Answer:

A

Step-by-step explanation:

Since the theta is in second quadrant, x will be negative and y positive. cos(theta)=-2/sqrt(29)=B/H, the base is 2 and H=sqrt(29). The perpendicular is 5.

Answer:

15/2 miles or 7 1/2 miles per hour.

Step-by-step explanation:

We can write the ratio shown as 5 : 2/3. We would need to divide both sides by 2/3 to get our answer. 2/3÷2/3=1 and 5÷2/3 would be 15/2. So the ratio would now look like this: 15/2 : 1. Hope this helped.

The average speed is 7.5 miles/h

The average speed of a body is equal to the total distance covered, divided by the total time taken. The formula for average speed is given as:

Average Speed Formula:

Average Speed = Total distance covered ÷ Total time taken

given:

distance= 5 miles =

time= 2/3 hour

So, average speed

=distance/ time

=5/ 2/3

= 15/2

=7.5 miles/ h
