Explain how you can find 3x584 using expanded form

Answers

Answer 1

I believe what you need to do is multiply 3 by each number.
To start, 3*584 is 1752. Expanded form written out would be (3*500)+(3*80)+(3*4). Simply multiply all the numbers and then add them together. 3*500=1,500; 3*80=240; 3*4=12. 1,500+240=1740+12=1752. Hope this helps! :)

In the seventh grade, the ratio of girls to boys is 7:5. If there are 21 girls in the seventh grade, how many boys are there?

Answers

There is 15 boys in the Seventh Grade

So we are given the fraction ratio...

7 girls

---------

5 boys

if we make the fraction

21 girls

----------

x boys

equal each other, we can cross multiply and find x.

Cross multiplying means to multiply 7 times x and 21 by 5.

then we set up a little equation

7x = (21)(5) First lets solve what 21 times 5 is

7x = 105 Now we have to divide both sides by 7 to get x alone.

÷7 = ÷7 On the left side of the equation the 7 cancels and we solve on the right.

x = 15

So we know that when we have 21 girls in the 7th grade classroom we also have 15 boys.

what is the area of the science lab table that is 60 by 48 inches in feet?

Answers

2880 is the area in inches and 240 is the area in feet.

Most tables are rectangular so we can use the rectangle area formula:
[tex]A = L * W[/tex]

A = 60 * 48
A = 2880

Convert inches to feet.

2880 inches = 240 feet

So, the answer is 240 square feet.

[tex] \frac{11(9^2-5^2)}{2^2+8} = \frac{11(81-25)}{4+8} = \frac{11*56}{12} = \frac{11*28}{6} = \frac{11*14}{3} = \frac{154}{3} [/tex]= 51.333333333 ≈ 51.3

Hence, the answer is C.

Answer:

51.3

Step-by-step explanation:

In order to calculate this, you have to remember the norms for the solution of math problems with hierarchy of operations called PEMDAS:

Parentheses (simplify inside 'em)

Exponents

Multiplication and Division (from left to right)

Addition and Subtraction (from left to right)

So we first solve parentheses:

11[(9^2-5^2)= 11(81-25)=11(56)= 616.

and now we have to divide that by the result of:

2^2+8

Remember first exponents:

2^2+8= 4+8=12

ANd now we just divide:

616/12=51.3333

So the answer would be 51.3

Answers

I graphed these vertices myself in the attached photo, and it turned out to be a rectangle; With the thought that you perhaps made a typo and meant rectangle instead of polygon I continued on and found the perimeter of the rectangle.

The formula for finding the perimeter of a rectangle is P = 2(l+w).

I counted the units of the long side (K & J) to get the length, which is 7.

Next, I counted the units between J & H to find the width which is 4. Now we're ready to use the formula.

First I will add the length plus the width, 7 + 4 = 11.

Then I will multiply 2 x 11 to get a product of 22.

Solve the equation for 15 points PLEASE HELP!!!!!!!

Answers

Relax! This isn't so hard once you grasp it. In an equation like this, what's the first step? Distributive property, right? Multiply 1/3 by 12, then by -24 v, and apply the same process to the other side. This leaves you with 4-8v=-8v+4. Now you need to isolate that variable. You have the same variable on both sides, so you do inverse of subtraction on either one. I'm going to choose the one on the right. You add 8v to both sides, leaving you with 4-v=4. Subtract 4 from the first side, and get -v=4. You aren't solving for -v, so flip the sign, and your final answer is v=-4. Make sense? (Let me know if it doesn't--I'm always willing to walk you through it some other way. I plugged it back in, and I am 100% sure that this answer is correct.)

The grass in the outfield of a professional baseball stadium is trimmed to a height of 5.08 * 10^-5 miles. Which unit of measurement is most appropriate to measure in height?

Answers

The height is given as 5.05 x 10⁻⁵ miles.

Because this is in English units, we should reduce the height to inches.

Note that
1 mile = 5280 ft
= 5280*12 = 63360 in

Therefore the height is
(5.08 x 10⁻⁵ miles)*(63360 in/mile) = 3.219 in

Answer:
3.2 in (nearest tenth)
The given measurement is in English units, so the conversion stays in English units.

Jim spends 3 1/2 days a month away from home if he does this for 6 1/2 months how many days would Jim be away from home

Answers

Final answer:

Jim would be away from home for approximately 23 days.

Explanation:

To find out how many days Jim would be away from home, we need to multiply the number of days he spends away from home in a month by the number of months he does this for:

3 1/2 days x 6 1/2 months = (7/2) x (13/2) = 91/4 = 22.75 days

Since we can't have a fraction of a day, we round up the decimal to the nearest whole number. So, Jim would be away from home for approximately 23 days.

By what percent will a fraction change if its numerator is increased by 60% and its denominator is decreased by 20%?

Answers

N/D --> 0.8N/0.4D = 2N/D

--> 100% increase
---------------
It's 100%, = 1 time larger, 2 times as large.

Answer:

It is increased by 100%. The numerator is two times more than the denominator. That's why original fraction will become [tex]\frac{2x}{y}[/tex].

Step-by-step explanation:

We need to find the percentage, if its numerator is increases by 60% and its denominator decreases by 20%.

First, we let the original fraction: [tex]\frac{x}{y}[/tex]

We have given its numerator is increases by 60% and denominator is decreases by 20% then,

New fraction will become = [tex]\frac{1.6x}{0.8y}[/tex].

Divide the new fraction by original fraction, then we get:

[tex]\frac{1.6x}{0.8y}[/tex]/ [tex]\frac{x}{y}[/tex]

[tex]\frac{1.6x}{0.8y}[/tex]* [tex]\frac{x}{y}[/tex]

Then, it will become [tex]\frac{1.6}{0.8}[/tex].

We can see that, The numerator is two times more than the denominator. That's why original fraction will become [tex]\frac{2x}{y}[/tex].

It is increased by 100%.

If we take an example, Suppose the original fraction is [tex]\frac{5}{8}[/tex] and the new fraction will become [tex]\frac{1.6*5}{0.8*8}[/tex].

= [tex]\frac{8}{6.4}[/tex] = [tex]\frac{80}{64}[/tex]

= [tex]\frac{10}{8}[/tex], it is twice of original fraction [tex]\frac{5}{8}[/tex].
