Answers

to find the area of a circle the formula is 3.14r^2. Answer is 12.56
using the circle area formula pi x radius squared, you do 2^2 * 3.14 = 4 * 3.14 = 12.56. since that’s a quarter of a circle, you divide it by 4 so you get 3.14

What property of equality would you use to solve the equation n/4 = 16.

Answers

Answer:

Multiplication Property of Equality.

Step-by-step explanation:

Isolate the variable, n. Note the equal sign, what you do to one side, you do to the other.

Multiply 4 to both sides of the equation:

(n/4) * 4 = (16) * 4

n = 16 * 4

n = 64

n = 64 will be your answer.

~

The equation n/4 =16,the answer is 64.

Seth deposited $40 in a savings account that earns 5% interest each year. How much interest will he earn in 1 year?

Answers

Answer:

$2

Step-by-step explanation:

The formula for simple interest is i = p*r*t, where r is the annual interest rate expressed as a decimal fraction.  Here the principal is $40 and the elapsed time is 1 year.  The amount of interest collectible after 1 year is thus:

i = ($40)(0.05)(1) = $2

Which are equivalent ratios to 3:4?
Check all that are true.

6:8

15:20

9:12

9:15

16:20

Answers

Answer:

6:8

15:20

9:12

How?

3:4*2=6:8

3:4*5=15:20

3:4*3=9:12

The equivalent ratio to the given to 3:4 are 6:8, 15:20 and 9:12

How to obtain real measurements from the ratio of two measurements?

Suppose the  real measurements were "a" and "b"

Then their ratio will be formed as

[tex]\dfrac{a}{b} = \dfrac{p \times x}{q \times x} = \dfrac{p}{q}[/tex]

where  is a common factor (not 1)

This shows that to get the real measurements from the given ratio, we need to assume to have some factor possibly cancelled from both the numerator and the denominator. Thus, a = px, b = qx

We are given the ratio as; 3:4

3: 4 x 2 = 6 : 8

3: 4 x 5 = 15 : 20

3: 4 x 3 = 9 : 12

Therefore, the equivalent ratio to the given to 3:4 are 6:8, 15:20 and 9:12

the farthest away number on the number line is the greatest number. (don’t worry about - its the same distance on left and right of the number line)
So if we look at the numbers it is clear that 16.5 is the greatest number. meaning it is the farthest from 0.
The answer is 16.5 because if you look at the number line it is farthest away

Answers

Answer:

I'm pretty sure that the answers would go, Wrong, increased, 9 1/2 points, 6 5/8 points, dropped, 12 3/4 points.

Step-by-step explanation:

The reason why it would be wrong is because the amount of points lost was less than the total amount of points gained.

In week one and two the company gained 9 1/2 points and 6 5/8 points. When you add them together, you get 16 1/8 points.

In week three the company lost 12 3/4 points. If you multiply the fraction to change the denominator to 8, the mixed fraction becomes 12 6/8.

16 1/8 - 12 6/8 = 3 3/8

As you can see, there are still points left over.

In the fourth week, they ended up losing all of their points and then some more, but from my understanding it's just asking about the third week.

Hope that this helps!

You need to find a common denominator I chose 28 so I multiplied 4 by 7 and that gives you 28 and you have to do the same thing to the top that you did to the bottom so I multiplied 11 by 7 as well which gave me a fraction of 77/28 then I multiplied 7 by 4 to get 28 and multiplied the top by 4 to get a fraction of 20/28 then I added 8 to 20/28 and to 77/28 to get 28/28 (the whole fence) and 85/28 (the paint you need to cover the whole fence) then I simplified my answer by seeing how many times 28 fit into 85 and it fits 3 times with a remainder of 1 so the simplified answer I got was 3 and 1/28 gallons of paint to cover the whole fence.

Answer:

24.44 percent

Step-by-step explanation:

F=Friday

S=Saturday

P(F or S)= 20/90+22/90-20/90=22/90

22/90 as percentage is 24.44 percent

Answer:

For Friday, 22% of the check in's happened on that day. For Saturday, 24% of the check in's happened on that day. For both days combined, 46.66% of the check in's happened for both.

Step-by-step explanation:

Overall there were 90 check ins. Since 20 happened on Friday, it would be 20/90, which is 22%. Saturday, 22 check ins happened, so it would be 22/90, which is 24%. Overall, between Friday and Saturday, 42 check in's happened, so it would be 42/90, which is 46.66%.
