What is the value of b. If A+B=C and A=35 and C=25
Explain how you got this answer

Answers

Answer 1

Answer:

[tex]B=-10[/tex]

Step-by-step explanation:

Hi!

So let's write the equation again

[tex]A+B=C[/tex]

The next step is to plug in known values:

[tex]35+B=25[/tex]

Now we solve this as a normal algebra equation:

Do same to both sides

[tex]B = 25-35[/tex]

[tex]B=-10[/tex]

I hope this helped. Let me know if you have any questions

Answer 2
The answer is -10. No positive number could equal 25 and if 35-25 is 10, it would only make sense to be negative. Say if you have $25 but you need 35, you’d be in debt of $10 you borrowed from someone else. Hope this makes sense, I’m not the best at explaining.

William gets a student loan to pay for his college tuition. He borrowed $2,500 for 10 years at an interest rate of
8%. How much will William pay in interest on this loan?

Answers

Answer:

2897.31

Step-by-step explanation:

I'm going to assume two things

The interest rate is compoudning annually

There is only one payment (at the end of the 10 years)

To find the amount of interest paid on this loan we first need to calculate the future value (or accumulated value)

FV=PV(1+i)^n

Plug in our numbers

2500(1+.08)^10

Run this through a calcuatlor and get 5,397.31

This is the future value and the question is asking for the interest paid which is just the FV-PV

Which means we have

5,397.31-2500

our answer is 2897.31

Answer:


2897.31

A. Find the circumference of the tire.
B. About how many times will the tire have to rotate to travel 1 mile? (1 mile = 5,280 ft)

Answers

Answer:

Answer Below

Step-by-step explanation:

The diameter of a tire is 2.5 ft. a. Find the circumference of the tire. b. About how many times will the tire have to rotate to travel 1 mile?

a) The circumference of a circle is the perimeter of the circle. The circumference of the circle is the distance around a circle, that is the arc length of the circle. The circumference of a circle is given by:

Circumference = 2π × radius; but diameter = 2 × radius. Hence:

Circumference = π * diameter.

Given that diameter of the tire = 2.5 ft:

Circumference of the tire = π * diameter = 2.5 * π = 7.85 ft

b) since the circumference of the tire is 7.85 ft, it means that 1 revolution of the tire covers a distance of 7.85 ft.

1 mile = 5280 ft

The number of rotation required to cover 1 mile (5280 ft) is:

number of rotation = 5280 ft/7.85 ft per rotation = 672 rotations.

Answers

Answer:

c

Step-by-step explanation:

when reflected across the x-axis the x becomes  negative and vise versa

when reflected across the y axis the y becomes negative and vise versa  

The new coordinates will be  [tex](5,1)[/tex] .

What are coordinates ?

Coordinates determine the position of the points or other geometric elements on graph.

We have,

Point [tex](5, -1)[/tex].

Reflected over x-axis,

So,

If a point [tex]( x,y)[/tex] under a reflection on the x-axis will be [tex](x,-y)[/tex] .

So,

according to the above mentioned statement,

Point [tex](5, -1)[/tex] reflected on the x-axis

We get ,

Reflected point [tex](5,1)[/tex] .

So, the new coordinates are  [tex](5,1)[/tex] .

Hence, we can say that the new coordinates will be  [tex](5,1)[/tex] .

(if you answer this may you please show your work)

Answers

Answer: Liz
To find the percent Liz got correct, you would do 47/50 to get 0.94. You would then move the decimal 2 places to get 94%.
94%>92%

Answer:liz scored better

Step-by-step explanation:

Liz scored better because how to find a percentage is dividing whatever two numbers you have by each other so it would be 47 / 50 which equals 0.94 then you times it by 100. Which would equal 94% which is better than a 92 which means Liz got the higher score
