Answer:

36

Step-by-step explanation:

The bolded letters are the differences in each step.

Your biggest friend in this problem is P.E.M.D.A.S (or synonyms to it)

It stands for Parenthesis, Exponents, Multiplication/Division, Addition/subtraction.

3[75÷(3^3-2•6)+7]

3[75÷(27-2•6)+7]

3[75÷(27-12)+7]

3[75÷15+7]

3(5+7)

3•12

The population of California is approximately 38,040,000. The population of Texas is about 2.606 × 10^7. What is the approximate
ivann1987 [24]
With scientific notation remember this rule; if the exponent is positive, move the decimal point that many places to the right. If it is negative move it that many places to the left. What that will do is make the number larger or smaller to the correct value.
 
So for example, if you had to solve 1.02 x 10^4 you would move the decimal four places to the right. So you would end up with 10200. 
As another example if you had to solve 1.02 x 10^-2 you would move the decimal two places to the left. That would give you .0120. 

So now we are onto your problem. 2.606 x 10^7.
You would move the decimal seven places to the right, because the exponent is positive, that will make your number larger(which would make more sense if you were adding populations, right?).
That would give you 26,060,000 people living in Texas.
From there simply add the two populations together and you will have your answer!

I really don't get this

Replace the CIRCLES by A and the SQUARES by B:

1) A + B = 14 And

2) A - B = 2

Add 1) + 2)

A+B   =14
A-B    = 2
------   ----
2A+0 = 16 then A = 16/2 = 8. If A = 8, then B = 6

So the CIRCLE = 8  and the SQUARE = 6

Select the correct answer.
Kaylis [27]

For this case we have that by definition, the volume of a rectangular prism is given by:

V = A_ {b} * h

Where:

A_ {b}:It is the area of the base of the prism

h: It is the height

A_ {b} = w * l

Where:

w: is the width

l: is the length

According to the data of the statement we have:

w = 16 \ in\\l = 4h\\V = 4,096 \ in ^ 3

Substituting the data we have:

A_ {b} = 16 * 4h = 64h\\64h * h = 4,096\\64h ^ 2 = 4,096\\h ^ 2 = \frac {4096} {64}\\h ^ 2 = 64\\h = \pm \sqrt {64}\\

We choose the positive value: h = 8

So the height is8 \ in

Answer:

8 \ in

PLS HELP ASAP

2) -6

8 is positive and 14 negative. You can either draw a number line and help yourself with that or since the negative one is bigger you can do the subtraction 14 - 8 and then change the sign of the answer.

Given the function, check all transformations that occurred from the graph of the function y=x^2
Hatshy [7]

Answer: left 7 units, up 4 units, and vertical compression

Step-by-step explanation:

Given

The function is y=x^2

First shift it to the left by 7 units, so the function becomes

y=(x+7)^2

Now compress it to make it one-third

y=\dfrac{1}{3}(x+7)^2

Now, sift the graph upward by 4 units

y=\dfrac{1}{3}(x+7)^2+4

Thus , the conditions are left 7 units, up 4 units, and vertical compression.
