Answers
Answer:
1. 18
2. 181
3. 101
Step-by-step explanation:
They want you to take each equation, and replace the letter with the number they give you after the equation.
3m + 2n + 4; m = 2, n = 4
This becomes
3(2) + 2(4) + 4
We multiply before we add, according to the order of operations. So next, the equation becomes:
6 + 8 + 4
= 18
———-
D^2 + 9k ; D = 10, k = 9
Numbers squared are numbers multiplied by themselves.
(10)(10) + 9(9)
= 100 + 81 = 181
——————-
3m + 4y x 2 ; m = 7, y = 10
3(7) + 4(10) x 2
21 + 40 x 2
Remember, multiplication always comes before addition.
21 + 80 = 101

Answers
Answer:
randomly requiring half the drivers to drive with sunglasses and the other half to drive without sunglasses.
Step-by-step explanation:
When employing an independent group design in a research or experimental study, the different groups in the study are assigned entirely different subjects such that, subjects in the treatment group are different from those in the control group. Therfore, adopting an independent group design in the scenario described above means diving the subjects into two at random with one half driving with sunglasses and the other half having to drive without it.

What is the radius of a cylinder that has a volume of 500 ft ³ and that is 10 ft tall?
Answers
Answer:
The answer is 3.98942, rounded its 3.99.
Step-by-step explanation:
Answer:
3.99 ft
Step-by-step explanation:
Volume of a cylinder = πr²h
π = 3.14
volume = 500 ft³
height = 10 ft
πr²h = 500
3.14×r²×10 = 500
r² = 500/3.14×10
= 15.92..
= √15.92
r = 3.9899.. ≈ 3.99 ft

What is 562,148,900 in expanded form

Answer:
562,148,900 =
500,000,000

+ 40,000
+ 8,000

Answer:
Hello!
First we need to understand what expanded form is!
Expanded form is a way of writing a number to see the value of each digit. An example is:
111
100 + 10 + 1 = 111
So we must find the value of 562,148,900, in expanded form.
First we would find the first digit, and separate it from the other digits.
5
Then, we would count the digits behind that, and add it to the right of the five, in the form of zeroes.
500,000,000
We would continue this process for each digit, and then we would put them in addition form.
Your final answer would be,
500,000,000
60,000,000 +
2,000,000 +
100,000 +
40,000 +

Answers
Answer:
80 ft^2 of paint would be needed
Step-by-step explanation:
Since we do not consider the roof, all we need do is to calculate the area of the shape without the roof side
So without the roof, we have 4 rectangles
we have 4 ft by 4 ft on both sides
Then 6 ft by 4 ft on the other two sides
mathematically, the area of a rectangle is the product of its sides
so, we have the total area as;
2(6 * 4) + 2(4 * 4)
= 2(24) + 2(16)
= 48 + 32
= 80 ft^2
