A father's age is three times the sum
of the ages of his two children.After 5
years his age will be two times the sum
of their ages.Find the present age of the
father​

Answers

Answer 1
Let the age of father be x years and sum of the ages of his children by y years.
After 5 years,
Father's age = (x + 5) years
Sum of ages of his children = (y + 10) years
From the given information, we have:
x = 3y ...(1)
and x + 5 = 2(y + 10)
x - 2y = 15 ...(2)
From (1) and (2), we have,
3y - 2y = 15 y = 15
x = 3y = 45
Father's age = 45 years

There are 15 circles and 12 squares. What is the simplest ratio of squares to total shapes?

Answers

4:5
They both divide by 3 so 12 divided by 3 is 4 and 15 divided by 3 is 5

The simplest ratio of squares to total shapes is 4 : 9.

The question wants the ratio to the total number of shapes so first find the total number of shapes:

= Circles + squares

= 15 + 12

= 27 shapes

There are 12 squares and 27 shapes. The ratio is therefore:

= 12 : 27

Use the lowest common factor of both numbers to find the simplest ratio. That factor is 3:

= [tex]\frac{12}{3} : \frac{27}{3}[/tex]

= 4 : 9

Darryl left the White House and traveled toward the ferry office at an average speed of 25 mph. Some time later Jacob left traveling in the opposite direction with an average speed of 35 mph. After Darryl had traveled for four hours they were 170 mi. Apart. How long did Jacob travel?

Answers

Answer:

2 hours

Step-by-step explanation:

Given the following :

Darryl :

Speed = 25mph

Jacob:

Traveled in opposite direction

Speed = 35mph

After Darryl had traveled for 4 hours, Distance between them was 170 miles

Distance traveled by Darryl :

Speed * time = (25 * 4) = 100 miles

Total distance = distance traveled by Darryl + distance traveled by Jacob

170 miles = 100 miles + distance traveled by jacob

Distance traveled by Jacob = 170 - 100

Distance traveled by Jacob = 70 miles

Time = distance / speed

Time traveled by Jacob = 70 miles / 35mph

Time traveled by Jacob = 2 hours

Jim and his friends are going to the Del Mar Fair and find they have two ticket options. In one option each person could buy an admission ticket for $5 and then pay $0.25 for each ride. The other option is to buy an admission ticket for $2 and then pay $0.75 a ride. What do you think Jim should do?

Answers

Step-by-step explanation:

let the cost of the options be y

since they are two already we can model the cost as

For the first ticket option

y=5+0.25(2)

y=5+0.5

y=$5.5

For the second ticket option

y=2+0.75(2)

y=2+1.5

y=$3.5

They should go for the second ticket option since it is $2 less than the first option

Hank has the choice of taking out a 30-year loan for $165,000 at 9.1% interest, compounded monthly, or the same loan at 20 years for a higher monthly payment. How much more is the monthly payment for the 20-year loan than the monthly payment for the 30-year loan? O A. $56.47 O B. $155.66 O c. $99.19 OD. $90.05​

Answers

If Hank has the choice of taking out a 30-year loan for $165,000 at 9.1% interest. The amount that the monthly payment for the 20-year loan is more than the monthly payment for the 30-year loan is: B. $155.66.

How to find the monthly payment?

For 30-year loan

P= principal = $165,000

r = Rate = 9.1% /12 = 0.00758

n = Number of months= 30years × 12 months = 360

So,

Monthly payment = 165,000×0.00758 × ( 1+0.00758)^360 / (1+0.00758)^360 -1

Monthly payment = 165,000×0.00758 × ( 1.00758)^360 / (1.00758)^360 -1

Monthly payment = 18,957.7574/14.15771760

Monthly payment = $1,339.04

For 20-year loan

P= principal = $165,000

r = Rate = 9.1% /12 = 0.00758

n = Number of months= 20years × 12 months = 240

So,

Monthly payment = 165,000×0.00758 × ( 1+0.00758)^240 / (1+0.00758)^240 -1

Monthly payment = 165,000×0.00758 × ( 1.00758)^240 / (1.00758)^240 -1

Monthly payment = 7,660.239666/5.12476186615

Monthly payment = $1,494.7

Difference = $1,339.04 - $1,494.7

Difference = $155.66

Therefore the correct option is B.

A video game store allows customers to rent games for $4.75 each. Customers can also buy a membership for $54 each year, and video games would then only cost $2.50 each to rent. Write and solve an equation to find the number of video games a customer would have to rent in a year in order for the two options to be equal.

Answers

Answer:

24

Step-by-step explanation:

Cost of membership + game = 2.50x + 54

Cost of just games = 4.75x

The catch is, how do we make up the 54 dollars?

So equate the 2 costs

4.75x = 2.50x + 54      Subtract 2.50

4.75x - 2.50x = 54       Combine

2.25x = 54                    Divide by 2.25

x = 54/2.25

x = 24

That means that 24 is the break even point.

In the ten thousands place is the number 8. To round to the nearest ten thousand, we have to look at the place value right behind it, the thousands place.

If the number in the thousands place is greater than or equal to 5, we round 8 up to 9. If the number in the thousands place is less than 5, we leave 8 as it is.

We can see that in the thousands place is the number 5, meaning that we round up to 9.
