Answer:

9.5

Step-by-step explanation:

(50/25)^2*2+5*0.3\\(2)^2*2+5*0.3\\4*2+5*0.3\\8+1.5\\9.5

To solve this you need to use PEMDAS (Parentheses, Exponent, Multiplication, Division, Addition, Subtraction).

PEMDAS is the order in which you need to do the problem.  First, do the work within the parentheses.  Then, do as the exponent require.  After that, multiply  as stated.  After all of this, you add in the end.

a family is building a rectangular fountain in the backyard. the yard is rectangular and measures 8x by 9x. The fountain is goin
densk [106]
Teachers often all this problem a donut problem because it’s like the donut hole getting cut out of the middle. The way that you solve this is to find the area of the whole yard and subtract the area of the fountain. Since they are rectangles we’re going to use A = LW
Area of yard - Area of fountain
A = (8x)(9x) - (2x)(5x)
A = 72 x^2. - 10 x^2
A 62 x^2

PLEASE HELP!!
madam [21]

Answer:

k=2/3

Step-by-step explanation:

Step 1:

Step 1 in solving the exponential equations is re-writing the base same as other side of the equation

so,

25^{3k}=625\\=> 25^{3k}=25^2

Step 2:

Second step is equating the exponents

The rule used is:

If\ B^m=B^n\ then\ m=n

So in this case

3k=2\\k = \frac{2}{3}

So the solution is:

k=2/3 ..

SpyIntel [72]

Of the 120 apartments in a building, 75 have been scheduled to receive new carpet. What fraction of the apartments have not been
Ilia_Sergeevich [38]

Hello!

To find the fraction of the apartments that have not been scheduled to receive new carpet, we need first need find the number of apartments not receiving new carpet, by subtracting the total amount of apartments, by the 75 that have been scheduled.

120 - 75 = 45 apartments

Next, we need to create a fraction. Since 45 out of 120 apartments not are scheduled to get new carpeting, the fraction of these values is 45/120. This can be reduced to 3/8.

Therefore, your final answer is 45/120, simplified to 3/8.
