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.

ANSWER IF YOU KNOW
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.
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.
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

HELLLP BRAINLY MORE THAN ONE ANSWER
Answer: I believe the answers will be 4,7, and 8
Step-by-step explanation:
Because g>10/3, and 10/3 is equal to 3 and 1/3. But g is more than 10/3. So the answers 4,7, and 8 will all be correct for they are more than 10/3.

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

May has 5 cups of dough. It takes 1/3 cup of dough to make one dinner roll. How many dinner rolls can she make with the dough she has?
Answer:
15 Rolls.
Step-by-step explanation:
This problem is one that can be solved simply by dividing.
Take 5, and divide that by 1/3.
However, you can't just do this. The way I did it was by turning 5 into 5/1. Then, Multiply by the reciprocal, which would be 5 x 3, which equals 15.

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
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)

How much will Jason earn, if he invests $8,000 at 7.5% interest rate for 18 months? How much will be in the account at the end of the 18 months?
Answer:
$8,900
Step-by-step explanation:
You don't say anything about compounding. If this problem involves only simple interest, then the interest will be i = p*r*t and the account balance will be i + p.
Here i = $8,000*0.075*1.5 (representing 18 months)
i + $900
At the end of 18 months there will be $8,000 + $900, or $8,900, in the account.
Answer:
$8,900

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
2 times what equals 10.3?
Answer:
5.15
Step-by-step explanation:
2 times what equals 10.3
To solve this problem, turn this into an equation and substitute the missing value for x.
2x=10.3Then, divide each side by 2 to isolate x.
x=10.3/2Solve.
x=5.15
