Friends Ramona and Heather go to different schools. Ramona has math class during first period on each of the 180 days she goes to school. She will be in math class a total of 8640 minutes this year. Heather’s school year also has 180 days, but her math class only meets every other day, so her class periods are longer. (One day she’ll have math class, and then the next day she won’t.) If Ramona and Heather end up with the same number of minutes of math class each year, how long are the class periods at Heather’s school?

Answer:

87/200 = 43.5     21/50 = 42/100

Step-by-step explanation:

What you need to do is make the denominator 100 by either multiplying or dividing. so you divide 87 and 200 by 2 to get denominator 100 and get 43.5/100. Then, you multiply 21/50 by 2 to get denominator 100 and get 42/100. Mark as barinliest pls

Answer:

230 2/3 ft

Step-by-step explanation:

Perimeter means add all four sides together

60 5/6 + 54 1/3 + 56 1/6 + 59 1/3

First convert these numbers into improper fractions (it makes adding them together easier)

To convert mixed numbers into improper fractions we multiply the whole number by the denominator and add the numerator (whole number × denominator + numerator)

365/6 + 163/3 + 337/6 + 178/3

To add fractions together they must have a common denominator

A common denominator of 3 and 6 is 6 because 3 × 2 = 6 and 6 × 1 = 6. If we multiply the denominator, then we must also multiply the numerator by the same number

(365/6 × 1/1) + (163/3 × 2/2) + (337/6 × 1/1)+ (178/3 × 2/2)

365/6 + 326/6 + 337/6 + 356/6

Add the numerators together

365 + 326 + 337 + 356 = 1,384

Put the new numerator over the same denominator (6)

1384/6

Both the numerator and denominators are even numbers which means they can be simplified by 2

Divide both the numerator and denominator values by 2

1384 ÷ 2 = 692

6 ÷ 2 = 3

692/3

3 is a prime number so it can no longer be simplified

Now we must convert it back to a mixed number

How many times does 3 evenly go into 692?

If you do long division or use a calculator, you'll notice 692 ÷ 3 = 230.6666666667

Disregarding the decimal values, 230 is how many times 3 goes evenly into 692

230 x/3

Now we must find the numerator

Since 3 evenly fits 230 times, multiply 3 and 230

3 × 230 = 690

This is not 692 so find the difference

692 - 690 = 2

This means the numerator value will be 2

230 2/3 is the answer

Step-by-step explanation:

To dialate means to change in size. K is the scale factor basically, and since K=7, we are going to multiply each of the coordinates by 7:

A(-3,1) -> A'(-21,7)

B(2,4) -> B'(14,28)

C(0,-4) -> C(0,-28)

See how we got those now?

Answer:

N = 4

Step-by-step explanation:

I dont know how to show this work.

You basically simplify both sides to find N

And after that you isolate the variable...

Answer:

n = 4

Step-by-step explanation:

We need to make the fraction equal 1, so the equation reads 3 = 2 + 1. To make it 1, n has to be 4 because 4 divided by 4 is 1. We can fact check, too. Just do 3 = 2 + 4/4. 4/4 equals 1. Rewrite it as 3 = 2 + 1, which is obviously correct.

Answer: 2^60 = 8^20

Step-by-step explanation: 8=2^3

(2^3)^20 Multiply the exponents

2⁶⁰ written as an exponent with a base of 8 is 8²⁰

From the question,

The given expression is 2^60

In order to write this as an exponent with a base of 8,

First, let us write the given exponent properly.

The given exponent can be properly written as 2⁶⁰

Now, to write this as an exponent with a base of 8, we will apply one of the laws of indices

From one of the laws of indices, we have that

xᵃᵇ = (xᵃ)ᵇ

Then,

2⁶⁰ can be expressed as 2³⁽²⁰⁾

That is,

2⁶⁰ = (2³)²⁰

But, 2³ = 8

∴ 2⁶⁰ = (2³)²⁰ = 8²⁰

2⁶⁰ = 8²⁰

Hence,  2⁶⁰ written as an exponent with a base of 8 is 8²⁰

Answer:

4 1/7

Step-by-step explanation

Basically the line is a division line so it would be 29 divided by 7. The answer would be 4 with one left over. I tried to make that make sence if it doesn't sorry.

Answer:

4 1/7

Step-by-step explanation:

The first thing you want to do is see how many times 29 can go into seven. To do that, review your multiplication facts. We know that 7, 14, 21, 28, and 35 are all multiples of seven. Since 35 is too big, we take the smaller number, 28. 7 times 4 is 28, so we add 4 to the whole numbers and subtract 28 from 29, leaving us with 4 1/7
