If $2,500 is deposited into a new account that earns 2% interest compounded quarterly and there are no other deposits or withdrawals, how much interest is earned after 15 years?

Answers

Answer:

The amount is $3372.13 and the interest is $872.13

Step-by-step explanation:

Interest is the monetary charge for the privilege of borrowing money.If $2,500 is deposited into a new account that earns 2% interest compounded quarterly and there are no other deposits or withdrawals,

then  864.671 is the interest earned after 15 years.

What is Interest?

Interest is the monetary charge for the privilege of borrowing money.

Given that  $2,500 is deposited into a new account that earns 2% interest compounded quarterly and there are no other deposits or withdrawals, We need to find how much interest is earned after 15 years.

After 15 years,

Amount=2500×(1+2%)^15

=3364.671

The formula for interest is given below,

Interest=Amount-Capital

=3364.671-2500

=864.671

Hence 864.671 is the interest earned after 15 years for $2,500 is deposited with 2% interest compounded quarterly and there are no other deposits or withdrawals.

Andre also has a puppy that weighs 9 pounds. The vet says that this puppy is now at about 30% of its adult weight. What will be the adult weight of Andre’s puppy?​

Answers

Answer:

30 lbs.

Step-by-step explanation:

There is a much easier way to do this involving percentages, but I hate percentages so here is my way.

The adult weight will be 100% and the puppy is currently around 30%. If you multiply 30% by 3, you get 90% which is almost 100%.

So I multiplied 9 by 3 to get 27 lbs.

Now I need to get the remaining 10%. 9 lbs is 30%, soto get to 10%, I divide 30% by 3. I divided the 9 lbs by 3 to get 3 lbs.

Add the two numbers together: 27+3=30 lbs

Answer:

-8m - 6

Step-by-step explanation:

-2m -6( m + 1 )​

Distributive property (multiply what is in the parenthesis by what is out of it)

-2m -6 * m + -6 * 1

-2m -6m - 6

Combine like terms

-2m + -6m = -8m (remember 2 negatives numbers added will give you a bigger negative number so think of it as adding 2 numbers and then putting the negative sign in front of it)

-8m - 6

You cannot simplify it anymore, since it's not like terms

x = 8

Can someone please help me with this question really need help

Answers

Area: 93.5
Perimeter: 39

8 1/2 is converted to 8.5
So to find the area we multiply the length and the width:
8.5 x 11 = 93.5

To find the perimeter we add up each side of the rectangle so:
8.5 + 8.5 + 11 + 11 = 39


Marla and some friends are on a road trip. Marla was assigned to drive 3/7 of the total trip. She has already driven 3/5 assigned driving duty. How much of the total trip has Marla driven. The solution will go on the right side of the equation

Answers

Answer:

9/35

Step-by-step explanation:

Let x be the total trip distance.

Since Maria is assigned to drive 3/7 of the total trip, she is to drive 3x/7.

Now, since Maria has driven 3/5 of 3x/7, the amount of the total trip she has driven is 3/5 × 3x/7 = 9x/35.

So, Maria has driven 9/35 of the total trip.

Answer:

C. x = 4√70

Step-by-step explanation:

To find x, we would apply the leg rule.

Leg rule is:

Hypotenuse/leg = leg/part

Hypotenuse = 36 + 20 = 56

Leg = x

Part = 20

Plug in the values into the equation

Thus, we would have:

56/x = x/20

Cross multiply

x*x = 56*20

x² = 1,120

x = √1,120

x = √(16*70)

x = 4√70

The correct answer is c.

3(x-5)=6 What is the answer?​

Answers

Step-by-step explanation:

3(x - 5) = 6

x - 5 = 2 (divide 3 on both sides)

x = 7 (add 5 on both sides)

The solution is x = 7.

3(x-5)=6

multiply 3 by x and -5

3x-15=6

add 15 on each side

it cancels out on the left nd on the right u get 21

so it would be

3x=21

divide by 3 on each side

X=7

The surface areas of two cubes have a ratio of 49 to 81. What is the

A

7 to 9

B

1 to 32

C

32 to 49

D

3 to 4

Answers

Answer:

A

7 to 9

Step-by-step explanation:

We have that:

The ratio of the edges is x.

The ratio of the surface areas is given by [tex]x^2[/tex]

The ratio of the volumes is given by [tex]x^3[/tex]

In this question, we have that:

[tex]x^2 = \frac{49}{81}[/tex]

So

[tex]x = \sqrt{\frac{49}{81}} = \frac{7}{9}[/tex]

So the correct answer is given by option A.

The side of the base of a square pyramid is increasing at a rate of 666 meters per minute and the height of the pyramid is decreasing at a rate of 111 meter per minute. At a certain instant, the base's side is 333 meters and the height is 999 meters. What is the rate of change of the volume of the pyramid at that instant (in cubic meters per minute)

Answers

Answer:

[tex]105m^3/min[/tex]

Step-by-step explanation:

We are given that

Base side of square pyramid, a=3 m

Height of square pyramid, h=9m

[tex]\frac{da}{dt}=6m/min[/tex]

[tex]\frac{dh}{dt}=-1/min[/tex]

We have to find  the rate of change of the volume of the pyramid at that instant.

Volume of square pyramid, V=[tex]\frac{1}{3}a^2h[/tex]

Differentiate w.r.t t

[tex]\frac{dV}{dt}=\frac{1}{3}(2ah\frac{da}{dt}+a^2\frac{dh}{dt})[/tex]

Substitute the values

[tex]\frac{dV}{dt}=\frac{1}{3}(2(3)(9)(6)+(3^2)(-1)[/tex]

[tex]\frac{dV}{dt}=105m^3/min[/tex]

Hence, the rate of change of the volume of the pyramid at that instant=[tex]105m^3/min[/tex]

A cash register contains only five dollar and ten dollar bills. It contains three times as many five dollar bills as ten dollar bills and the total amount of
money in the cash register is $950. How many ten dollar bills are in the cash register?

Answers

Answer:

38

Step-by-step explanation:

Let x be the number of ten dollar

Number of five dollar=3x

Total amount of money in the cash register=$950

We have to find the number of ten dollar bill in the cash register.

According to question

[tex]5\times (3x)+10x=950[/tex]

[tex]15x+10x=950[/tex]

[tex]25x=950[/tex]

[tex]x=\frac{950}{25}[/tex]

[tex]x=38[/tex]

Hence, number of  ten dollar bills  in the cash register=38
