I don’t understand how to solve it

Mathematics
1 answer:
kykrilka [37]3 years ago

Answer:

x= $878.85

Step-by-step explanation:

1349.99=1350

1350=100%     you cross multiply and then divide by 100 you get x = 540

  x   =40%

504 is how much can be off the original price, 1350-504=810

You would pay 810 dollars if the coupon was 40% off. Now we gotta find how much is the tax rate.  

810=100%    do the cross multiply and then divide by a 100, you get x=68.85

x   =8.5

 Then you have to add your tax rate to the price that you are paying, 810+68.85=$878.85.

Hope this helps you!

You can know that 236 is a composite number because it is divisible by _____. A. 2 B. 3 C. 7 D. 6
kaheart [24]

A. 2

<h2>Explanation:</h2>

A composite number can be formed if you multiply two smaller positive integers. So the result is also a positive integer. Let's test each option:

Option A.

\frac{236}{2}=118 \\ \\ \\ So: \\ \\ 236=2\times 118

236 can be formed by multiplying two smaller positive integers that are 2 and 118.

Option B.

\frac{236}{3}=78.67 \ It's \ not \ an \ integer

Option c.

\frac{236}{7}=33.71 \ It's \ not \ an \ integer

Option d.

\frac{236}{7}=39.33 \ It's \ not \ an \ integer

<em>Only Option A meets the requirements.</em>

Find the value of the missing coefficient in the factored form of 27f^3 + 125g^3. 27f^3+125g^3=(3f+5g)(9f^2-?fg + 25g)^2
7nadin3 [17]

Answer:

15

Step-by-step explanation:

The formula for factoring a sum of cubes is:

a^3+b^3=(a+b)(a^2-ab+b^2)

We have a=3f and b=5g here.

So a*b in this case is 3f*5g=15fg.

The ? is 15.

Nikolay [14]
First, you would create an equation for this problem. 
\frac{18}{15}= \frac{x}{100}

Next, you would cross multiply. 
15x = 1,800

Now, you would isolate the x. To do this, you would divide both sides by 15. 
x = 120

It is a 120% increase. 

I hope this helps!
