Answer:
16 minutes
Step-by-step explanation:
80% of 20 is 16, so thats your answer.
Answer:
25 Minutes.
Step-by-step explanation:
This can be solved simply by long division. First, change 80% into its decimal form, which is 0.80, and is simplified to 0.8. Then, divide 20 by 0.8.
Which expression represents the product of two factors?
A.8 + ( x - 1)
B.(7 + x)(10 - 1)
C.(11 + x) + (8 - 3)
D.x ÷ (10 - 1)
Thirteen less than a number is 70 write the as an expression
x - 13 = 70. x represents what needs to be subtracted by 13 to get 70.

3.2+1.4= 4.6
Plz, identify The error.
Correct the work.
Share a strategy if u would like. :)

!!Giving 15 points and will give brainliest!!Use the second list of random numbers to again calculate the experimental probability of a group having at least three girls. The results using the second list are
10%
the results using the first list.
Answer:
39% chance for only boys, 61% chance for only girls for the first two questions
the second is a bit trickier,you need a ratio for finding how many would be in 224 groups.
100:224 = 61:x, or 61/100 = x/224
Cross multiply; 100x=13664
Then, divide by 100; x=136.64, or about 137 groups would contain all girls
Step-by-step explanation:
Answer:
39% 61%

the boeing 747 airplane is 250 feet in length. If a model of this airplane is 8 inches long, what scale was used to create the model.
please help!!!
answer: The wingspan is 36 m.
Using a proportion to solve this, we write the scale factor as a ratio first: 19/38, since 19 is the size of the model's length and 38 is the real length. For the second ratio, we have 18 for the size of the model wingspan and x for the real wingspan:
19/38 = 18/x
Cross multiply:
19*x = 38*18
19x = 684

Shawna says, “I can show$1.75 using only quarters.” Is Shawna correct? Explain
Answer:
Yes Shawna is correct
Step-by-step explanation:
Answer:
Yes, she is.
Step-by-step explanation:
A quarter is worth 1/4 of a dollar, or 25 cents. Four quarters are in a dollar. So it'd be seven quarters would equal $1.75.

Step-by-step explanation:
I need 3 paragrahps Please read the promtp !
Before we write 3 paragraphs, we need to solve the equation ourselves using the order of operations.
Order of Operations: Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction. (PEMDAS)
3 · (10 - 2) + 4²
3 · (8) + 4²
3 · (8) + 16
24 + 16
40
Finally, here's the prompt:
The requirements of the prompt are to show step-by-step how to solve the problem and to explain the order of operations in 3 paragraphs.In order to solve the equation, we have to understand the order of operations, which is the order used in solving expressions. The order of operations are parenthesis, exponents, multiplication, division, adding, and finally subtracting. It's usually abbreviated to 'PEMDAS'.
The first step of solving the equation is solving what's in the parenthesis, which is 10 - 2. By subtracting, you should get 8. The second step is solving the exponents, which is 4 to the second power. to do that, we multiply 4 by itself, so we should get 16. Now, for the third step, we have to multiply 3 x 8 before we add 16 so we follow the order of operations. After multiplying 8 x 3, you should get 24.
Now, all that's left is to add 24 and 16. Our answer should be 40. That's how you solve the equation using order of operations. In this equation, we only used parenthesis, exponents, multiplication, and addition. Even though there was no division or subtracting (besides subtracting in parenthesis), we still follow the order of operations.
Answer: I did Parenthesis, I subtracted 10-2, that gave me 8. Next I did exponents, I multiplied 4 twice or to the 2nd power. That gave me 16. Then I multiplied 3 and 8 and that equals 24. After that the only thing left to do is add 16 and 24 which equals to 40. That's how I got my answer by using PEMDAS. I followed the order of operations even though I didn't have to use division.

Allison drew a number line to model seven eighths − two eighths. Is the model correct? Explain why or why not. You can write out the fraction names or use the forward slash (/) on your keyboard to represent the fraction bars.
A number line from zero to one partitioned into eighths. There are five hops beginning at seven eighths and ending at two eighths.
did it show the number line she threw?
Answer:
no, because the number line shows the arrow going backward, so now we know its subtraction, so you're going to count backward until you reach the number we are looking for so 7/8 minus 2/8 equals 5/8.

Select the THREE equations that this diagram could represent.
Question
Select the three equations that this diagram could represent.
Answer
Well, we first have to find out what the diagram says.
So what the diagram says is that 18 + 18 + 18 = 54.
Given this information, we have to figure what other answers = 54.
Therefore the answers are
(A) 18 * 3 = 54.
(D) 54/18 = 3
(E) 54/3 =18
Trevor is having trouble understanding how the degree of a nonzero constant is 0. Use the expression 3x^0 to help explain this concept to Trevor.
A. The degree of a monomial is the sum of the number of its variables. In the expression 3x^0, the value of the exponent is 0. Any number or variable raised to the power of 0 is 1. So, 3x^0 is equivalent to 3(1), or 3. Therefore, the degree of the nonzero constant 3 is 0.
B. The degree of a monomial is the coefficient of its variable. In the expression 3x^0, the value of the exponent is 0. Any number or variable raised to the power of 0 is 1. So, 3x^0 is equivalent to 3(1), or 3. Since the expression has no variables, the degree of the nonzero constant 3 is 0.
C. The degree of a monomial is always zero. Therefore, the degree of the nonzero constant 3 is 0.
D. The degree of a monomial is the sum of the exponents of its variables. In the expression 3x^0, the value of the exponent is 0. Any number or variable raised to the power of 0 is 1. So, 3x^0 is equivalent to 3(1), or 3. Therefore, the degree of the nonzero constant 3 is 0.
Answer:
The answer is B

Answer:
1) 2 boots for 7 shoes = 8 boots for 7x4 shoes (28 shoes)
2) 7 shoes for 2 boots = 49 shoes for 2x7 boots (14 boots)
Answer:
1. 28
2. 14
Step-by-step explanation:
1. As you can see on the bottom 2x4=8 (or 8 divided by 2) so all they did was multilpy the first number by four so to get the second number on the top you have to do the same thing (7x4=28)
2. Now that you have the second number on the top you can find the third number on the bottom. So all you have to do is divide 49 by 28 which is 1.75, then you would go down to the bottom and do 8 times 1.75 and you get 14
