The answer is D
This is because if for every $50 he saves $5, and he has saved a total of $500, you can set up a proportion to find out how much money he has saved at that point.
The proportion is as follows:
50/5 == 500/x
x is equivalent to the amount of money he has saved
You can cross multiply to get the following equation:
50x == 2500
To isolate x, you must divide both sides by 50, giving you an answer of:
x = 50
This is the same as option D

what is the square root of 864
There are two ways to evaluate the square root of 864: using a calculator, and simplifying the root.
The first method is simplifying the root. While this doesn't give you an exact value, it reduces the number inside the root.
Find the prime factorization of 864:
[tex]\sqrt{864} = \sqrt{2 \cdot 2 \cdot 2 \cdot 2 \cdot 2 \cdot 3 \cdot 3 \cdot 3}[/tex]
Take any number that is repeated twice in the square root, and move it outside of the root:
[tex]\sqrt{864} = \sqrt{(2 \cdot 2) \cdot (2 \cdot 2) \cdot 2 \cdot (3 \cdot 3) \cdot 3}[/tex]
[tex]\sqrt{2 \cdot 2} = \sqrt{4} = 2[/tex]
[tex]\sqrt{3 \cdot 3} = \sqrt{9} = 3[/tex]
[tex]\sqrt{(2 \cdot 2) \cdot (2 \cdot 2) \cdot 2 \cdot (3 \cdot 3) \cdot 3} = \sqrt{(4) \cdot (4) \cdot 2 \cdot (9) \cdot 3}[/tex]
[tex]\sqrt{(4) \cdot (4) \cdot 2 \cdot (9) \cdot 3} = (2 \cdot 2 \cdot 3) \sqrt{2 \cdot 3} = \boxed{12 \sqrt{6}}[/tex]
The simplified form of √864 will be 12√6.
The second method is evaluating the root. Using a calculator, we can find the exact value of √864.
Plugged into a calculator and rounded to the nearest hundredths value, √864 is equal to 29.39. Because square roots can be negative or positive when evaluated, this means that √864 is equal to ±29.39.
Mariah bought 7 books $11.20 each. Find the total cost of the 7 books. Justify your answer by using the Distributive Property.
Answer
Let's just get the answer so that you see what we are trying to do with the distributive property.
Cost = C = n (number of books) * Cost of 1 book.
Cost = 7 * 11.20
Cost = 78.40
Distributive Property
11.20 * (4 + 3)
11.20 * 4 + 11.20 * 3
44.80 +33.60
78.40 which agrees with the multiplication answer
To calculate the total cost we have to multiply 7 books by the cost of each book
Total = 7*$11.20 = $78.4
Answer : $78.4

Clara and Toby are telemarketers. Yesterday, Clara reached 4 people in 10 phone calls, while Toby reached 3 people in 8 phone calls. If each telemarketer continues at the same rate, who will reach more people in 40 calls?How many more?
I hope this helps you.
4/10 = .4
3/8 = .375
.4 > .375, so Clara will reach more people
Another way to look at it:
4/10 * 40 to 4 * 4 = 16 people reached
3/8 * 40 to 3 * 5 = 15 people reached
Answer: Clara will reach more people with 1 more
Step-by-step explanation:
To solve this question, we will find the total number of people Clara can reach in 40 calls and we will also find the total number of people Toby can reach in 40 calls and then we will compare the two to be able to determine who can reach more people in the 40 phone calls.
We can use proportion to find the total number of people Clara reached in 40 calls
Let x be the total number of people Clara can reach in 40 phone calls
Since Clara can reach 4 people in 10 phone calls. Then;
4 people = 10 calls
x = 40 calls
cross multiply
10 × x = 40 × 4
10x = 160
Divide both-side of the equation by 10
10x/10 = 160/10
x = 16
The number of people Clara reached in 40 calls is 16
Now, we can also use the same method to get the number of people Toby can reach in 40 calls.
Let x represent the number of people Toby can reach in 40 calls.
Since Toby can reach 3 people in 8 calls. Then;
3 people = 8 calls
x = 40 calls
cross multiply
8 × x = 40 × 3
8x = 120
Divide both-side of the equation by 8
8x/8 = 120/8
x = 15
The number of people Toby can reach in 40 calls is 15.
Now compare;
Clara can reach 16 people in 40 calls
Toby can reach 15 people in 40 calls
Therefore, Clara can reach more people than Toby in 40 calls
Clara can reach more people in 40 calls with 1 more person

Your class has 30 students. If 13 of them walk to school, how many students in your class walk to school?
Out of a class of 30 students, 13 students walk to school. This is the exact number provided in the question itself.
The question asks how many students in your class walk to school if the class has 30 students and 13 of them walk to school. The answer to this is quite straightforward: if 13 students out of the 30 walk to school, then the number of students who walk to school is 13. There's no need for complex calculations or additional data; the information provided directly gives us the answer.
10 students in your class walk to school.
To calculate [tex]\( \frac{1}{3} \)[/tex] of the total number of students walking to school, you multiply the total number of students by [tex]\( \frac{1}{3} \)[/tex].
Given there are 30 students in total, we multiply 30 by [tex]\( \frac{1}{3} \)[/tex]:
[tex]\[ 30 \times \frac{1}{3} = 10 \][/tex]
This means that [tex]\( \frac{1}{3} \)[/tex] of 30 students equals 10 students. So, in your class of 30 students, 10 of them walk to school.
This calculation is based on the principle that multiplying a number by [tex]\( \frac{1}{3} \)[/tex] or dividing by 3 is equivalent. So, dividing 30 by 3 gives us 10. Therefore, [tex]\( \frac{1}{3} \)[/tex] of 30 is 10.
The probable question may be:
Your class has 30 students. If 1/3 of them walk to school, how many students in your class walk to school?
2v+18=16-4(v+7) how does one do this
v = - 5
distribute right side of equation and simplify
2v + 18 = 16 - 4v - 28
2v + 18 = - 12 - 4v ( add 4v to both sides )
6v + 18 = - 12 ( subtract 18 from both sides )
6v = - 30 ( divide both sides by 6 )
v = [tex]\frac{-30}{6}[/tex] = - 5
The given equation is a linear algebra problem. By distributing, simplifying, and isolating the variable, we find that the solution to the equation 2v+18=16-4(v+7) is v = -5.
Explanation:The question is a linear algebra equation that you can solve by following these steps:
Distribute -4 to both v and 7 in the equation. You get 2v+18 = 16 - 4v -28. Simplify each side of the equation. 2v+18 becomes 2v+18 and 16 - 4v -28 simplifies to -4v -12. Transfer all the v values to one side and numeric values to the other. This results in: 2v + 4v = -12 - 18. Simplify again. You get 6v = -30.Isolate v by dividing both sides of the equation by 6. Thus, v = -30/6 = -5.So, the solution for the equation is v = -5.

What is 11/9/18 as a mixed number in simplest form.
The answer is 22 because in order to divide fractions (in this case we would have 11 as a fraction), you need to multiply one fraction by the reciprocal of the other fraction (the flipped form of a fraction).
To find this, we would do [tex]\frac{11}{1}[/tex] * [tex]\frac{9}{18}[/tex].
This would come to be [tex]\frac{198}{9}[/tex], and when simplified by dividing the numerator and denominator by 9, you get 22.

You have 19 digs for your current volleyball season. There are 5 games left in the season. You want to break your previous record of 26 digs in a season. Write and solve an inequality that represents the number x of digs you must get in the remaining 5 games to break your record
Answer:We must get more than 7 digs in the remaining 5 games to break record of 26.
Step-by-step explanation:
Given situation:- Let x represents the number of digs which we must get in the remaining 5 games to break your record ,and we have 19 digs for our current volleyball season.
To break previous record of 26 digs in a season, we have to get more than 26 i.e. 19 digs added to x must be greater than 26
⇒x+19 ≥ 26
⇒x≥26-19⇒x≥7
Therefore,we must get more than 7 digs in the remaining 5 games to break record of 26.
The inequality that represents the number x of digs you must get in the remaining is x > 7
Let 19 represent the digs you have in this season
Let x represent the digs you have in the remaining games.
Hence, x+19 will represent the digs you get for the season.
Now let solve an inequality that represents the number x of digs
19 + x > 26
x>=19-26
x > 7
Inconclusion The inequality that represents the number x of digs you must get in the remaining is x > 7.
