A father is 20 years older than his son. Five years ago,he was three times as old as his son was.Find their present ages​

Answers

Answer 1

Answer:

Dad=35, Son=15

Step-by-step explanation:

Well since the dad is 20 year older then the son we can call the son x and the dad x+20. Now five years ago the father was 3 times older then the so we construct the following equation:

x+20−5=3(x−5)

x+15=3x-15

x=15

So now we know that the sons age is 15 meanimg that since the dads 20 years older then him, his age is 20+15 which is 35!

Mary has $6,000 saved for her college education. She invested that money at 2.3% interest per year. Suppose her account earned interest compounded annually. How much interest would she earn in 3 years?

Answers

Answer:

Interest= $423.59

Step-by-step explanation:

Giving the following information:

Initial investment (PV)= $6,000

Number of periods (n)= 3 years

Interest rate (i)= 2.3% = 0.023

To calculate the Future Value, we need to use the following formula:

FV= PV*(1+i)^n

FV= 6,000*(1.023^3)

FV= $6,423.59

Now, the interest earned:

Interest= 6,423.59 - 6,000

Interest= $423.59

What is the value of r?
r= 4 ft
r= 8 ft
r = 16 ft
r = 32 ft

Answers

R=8ft

Step-by-step explanation:

Calculate r using the given formula

r = , with Area = 64π

r = ← cancel π on numerator/ denominator

r = = 8

The required value of radius of circle r is 8 ft

From Figure the area of circle is = 64π, we have to find the radius of the circle.

What is area of circle?

Area of the circle is = π[tex]r^2[/tex]

since

the area of the circle is given = 64π

And,
Radius = √area/π
radius= √64π/π
Radius = √64
Radius = 8 ft

Thus The required value of radius of circle r is 8 ft.

Hey y’all are you doing this morning I just got home from school and I’m just going to sleep in the morning I woke you to the sleep I love y’all I woke you to the sleep bye love y’all I woke

Answer:

There are 25 yellow flowers.

Step-by-step explanation:

The ratio is yellow/all and 5/9.

We know that all the flowers in total equal 45, which is a multiple of 9.

So 45 divided by 9 = 5.

So all I had to do was multiply 5/9 times 5/5.

So then we get the ratio of 45 total flowers with 25 yellow flowers.

Answer:

1) f = 16

2) h = 10

Step-by-step explanation:

all interior angles of a triangle add up to 180 degrees.

1) 46 + 67 + (4f+3) = 180

reduce:

4f+3 = 67

4f = 64

f = 16

2) 60 + 3h + 90 = 180

3h = 30

h = 10

Betsy has $4.25 and her brother has $16.00 they want to buy two water guns that cost $12.99 each and a bag of water balloons that cost $4.79. Do they have enough money if so how much money will they have left over. If not how much more money will they need?

Answers

Answer:

No they don't have enough money, they need $10.52

Step-by-step explanation:

So first, you will add 4.25+ 16.00 = $20.25 < This is the amount they have.

Second, they want two water guns so 12.99 x 2 = 25.98 < This is the price for the water guns.

Then, add the price of the water ballons to the guns which is $30.77 < This is the cost for everything they want to buy.

Subtract $30.77 from $20.25 to recieve the answer of $10.52

Here is a story: Lin bought 4 bags of apples. Each bag had the same number of apples. After eating 1 apple from each bag, she had 28 apples left.

Which diagram best represents the story? Explain why the diagram represents it.
What part of the story does
x
represent?
Describe how you would find the unknown amount in the story​

Answers

Answer:

Let's define the variable x as the number of apples in each bag.

We know that she bought 4 bags, then the total number of apples that she has is:

Apples = 4*x

Now she eats one apple for each bag, then she eats 4 apples, so she now has:

Apples = 4*x - 4

And we know that this is equal to 28, then:

4*x - 4 = 28

now we can solve this for x.

4*x = 28 + 4 = 32

x = 32/4 = 8

x = 8

There are 8 apples in each bag.

For the diagram part, by a small online search y found the image that you can see below.

The diagram that correctly represents this situation is diagram C, where x represents the number of apples in each bag.

Step-by-step explanation:

48+45+129+97 = 319 and 360-319 = 41

25/200 = 12.5% so 12.5% of 360 = .125x360 = 45

Sector 129 represents 129/360 = 35.83% so 200x.3583=72 cars

Given :

The sequence is -5 , -2 , 3 , 10 , 19 .

To Find :

The nth term of the given sequence .

Solution :

Difference between first 2 terms :

-2 - ( -5 ) = 3    1 term

3 - ( -2 ) = 5     2 term    

10 - 3 = 7         3 term

19 - 10 = 9       4 term

From the above observation we can say that difference is increasing in odd number .

So, the nth term will be :

[tex]a_{n+1}= -5 + (2n+1)[/tex]  for n greater than equal to 0.

Hence, this is the required solution.

y = 2/5x + 33/5

Step-by-step explanation:

(-9,3) and (1,7)

m=(y2-y1)/(x2-x1)

m=(7-3)/(1+9)

m=4/10

m = 2/5

y - y1 = m(x - x1)

y - 3 = 2/5(x + 9)

y - 3 = 2/5x + 18/5

y = 2/5x + 33/5
