Answer:
B. 20 over 32
Step-by-step explanation:
Because if you multiply both number by 4, you will get the ratio of 20:32
Final answer:
The equivalent ratio to 5 out of 8 players selected is 20 over 32, as both ratios reduce to the same value when simplified. Options A, C, and D are not equivalent to the original ratio of 5 to 3. Therefore, option(B) is correct.
Explanation:
The question asks about equivalent ratios. The tennis coach selected 5 out of 8 players to represent his academy, so the original ratio is 5 selected to 3 not selected (since 8-5 = 3). To find an equivalent ratio, we need to find multiples of both numbers that maintain the same relationship.
Option A, which presents the ratio 15 over 21, can be reduced by dividing both numbers by 3, yielding 5 over 7. This is not equivalent because 5 selected to 3 not selected is different than 5 to 7.
Option B, the ratio of 20 over 32, can also be reduced by dividing both numbers by 4, yielding 5 over 8. This is equivalent to the original ratio of 5 to 3 since the number of selected players would be scaled similarly. Therefore, the correct answer is B. 20 over 32.
Option C, 5 over 3, presents the opposite of the original scenario, where the numerator would represent the selected players, but this ratio does not need scaling, so it's not a valid equivalent ratio in this question.
Lastly, option D, 8 over 13, does not reduce to a ratio equivalent to 5 over 3 as these numbers have no common factors with 5 and 3 respectively.

A school district purchased 615 new laptops for their mobile labs. Each computer cost $409. What is the total cost for all of the laptops?
Answer: $251,535 is the total cost for all the laptops.
Step-by-step explanation:
615×409= 251,535
Answer:
[tex]total\ cost=\$251,535[/tex]
Step-by-step explanation:
For this exercise it is important to analize the information provided in the exercise.
According to the exercise, the of cost each computer is:
[tex]cost=\$409[/tex]
You know that the school district purchased 615 new laptops for their mobile labs; therefore, in order to calculate the total cost for all the laptops purchased, you must multiply the cost of one laptop ($409) by 615.
Therefore, you get that the total cost is the following:
[tex]total\ cost=(\$409)(615)\\\\total\ cost=\$251,535[/tex]

A holiday meal cost $12.50 a person plus a delivery fee of $30.
Which equation represents the amount a holiday meal
costs(y), including delivery, for x people?
Answer:
12.50x+30
Step-by-step explanation:
Answer:
[tex]y = 12.5x + 30[/tex]
Step-by-step explanation:
We are given the following information in the question:
Cost of a holiday meal = $12.50
Delivery fee = $30
Cost(y) represents the amount a holiday meal including delivery for x people.
[tex]cost = (\text{Cost of meal}\times x) + \text{Delivery chareges}[/tex]
Putting all the values,
[tex]y = 12.50\times x + 30\\y = 12.5x + 30[/tex]
The above equation gives the total amount of holiday meal for x people including the delivery charges.

minimum grade Anna can make on the final so that she
scores a 90 in the class?
a. 86
b. 91
C.
d
94
98
Answer:
b) 91
Step-by-step explanation:
Step 1: Multiple marks by its weights
Homework average: 95 x 20% = 19
Quiz average: 90 x 20% = 18
Test average: 87 x 40% = 34.8
Final exam: y x 20% = 0.2y
Step 2: Add all weighted averages and find y
19+18+34.8+0.2y = 90
71.8 + 0.2y = 90
y = 18.2/0.2
y = 91
Therefore, Anna needs to score minimum 91 in the final exam so that she can score a 90 in class.

Which is bigger 0.999 or 1.0?
Answer:1.0
Step-by-step explanation: 0.999 repeating is not a whole number like 1.0
Answer:
1.0
Step-by-step explanation:
Look at where the numbers are placed, in regards to the decimal point.
If a number is 1 place before a decimal point (For example 5.0) it is in the ones place.
If a number is 1 place after a decimal point (For example 0.1) It is in the tenths place.
Any numbers that are to the right the decimal are smaller than numbers to the left!

Charmaine will run less than 26 miles this week. So far, she has run 18 miles. What are the possible numbers of additional miles she will run? Use t for the number of additional miles she will run. Write your answer as an inequality solved for t
Answer:
18+t<26
t={1,2,3,4,5,6,7}
Step-by-step explanation:
18+t<26
alright, so you know that she will run less than 26. That means she cannot run 26 or 27 or any more miles than that.
She can run 19, 20, 21, 22, 23, 24, or 25 miles in total from her starting point which is 18.
She already ran 18 miles. If she ran one more it would be 19, if she ran 2 more it could be 20. But she CAN NOT pass 25 miles. (it is not less than OR equal to)
so let me put it like this:
18+1<26 yes because 18+1=19 which is less than 26
18+2<26 yes because 18+2=20 which is less than 26
18+3<26 yes because 18+3=21 which is less than 26
18+4<26 yes because 18+4=22 which is less than 26
18+5<26 yes because 18+5=23 which is less than 26
18+6<26 yes because 18+6=24 which is less than 26
18+7<26 yes because 18+7=25 which is less than 26
18+8<26 NOOO because 18+8=26 which is NOT less than 26 (it's equal, not less than)

Use the properties of exponents to complete the equivalent expression.
Answer:
15
Step-by-step explanation:
We can multiply powers with the same base
x^4⋅x^2=(x⋅x⋅x⋅x)⋅(x⋅x)=x^6
Properties of exponents are rules used to simplify mathematical expressions involving exponents. Examples are Power of a Power which means adding exponents when multiplying two expressions with the same base, and Quotient of Powers which is subtracting exponents when dividing two expressions with the same base.
Explanation:The question is about the properties of exponents. In mathematics, the properties of exponents refer to the rules that guide how expressions involving exponents are handled. For example, when you multiply two expressions with the same base, you add the exponents (also known as the Power of a Power property). So, an exponent like x^3 * x^2 simplifies to x^(3+2) = x^5.
Another example is the quotient of powers property, where you subtract the exponents when dividing two expressions with the same base. So, an expression like x^5 / x^3 simplifies to x^(5-3) = x^2.
These are just a couple of the basic properties of exponents. Other properties include the power of a product, the power of a quotient, zero exponent, and negative exponent. Each of these properties follows specific rules to simplify the expression involving exponents.

Answer:
Step-by-step explanation:
The graph of y= -4×+7 is a straight line with slope -4 and y-intercept 7. Please do not use × to represent the independent variable; use x instead. × represents multiplication.
To graph this function, first plot the y-intercept, b, which is (0, 7).
Next, starting with your pencil point at (0, 7), move the point 1 unit to the right and plot another point (which will be (1, 7) ). Now move your pencil point 4 units down and plot your third point, which will be (1, 3).
Finally, draw a straight line thru the first and third points, that is, thru (0, 7) and (1, 3). Notice how this line has the slope -4 and the y-intercept (0, 7).
