Answer:
395.85
Step-by-step explanation:
If the diameter is 12, then the radius must be 6. Following the formula of pi: 2 * pi * radius, our result is 37.7. 37.7 * 10.50 is 395.85
I really hope this helps. My memory of circles and pi isn't the best.
Explain, in detail, how you know if these are equivalent.
Answer:
they are equivalent.
Step-by-step explanation:
to find equivalent fractions, we need to multiply the numerator and denominator of the first fraction by the same number. this creates an equivalent fraction. 5 goes into 15 3 times, and 8 goes into 24 3 times. this shows that if we multiply both the numerator and denominator of the first fraction by 3, then we end up with the second fraction, proving that they are the same. hope this helps!
5/8. Each one you multiply by 3 is gonna be 15/24. 5 is a common factor of 15 and 8 is the common factor of 24
A school assembly had 600 students in attendance, and 35% of them were first-graders. How many first-graders were at the assembly?
can u also list the formula on how to do this while ur at it pls and ty
Answer:
210 Were First Graders
Step-by-step explanation:
35 percent of 600 is the same as 35 per hundred of 600. We can therefore make the following equation:
35/100 = X/600
To solve the equation above for X, you first switch the sides to get the X on the left side, then you multiply each side by 600, and then finally divide the numerator by the denominator on the right side to get the answer. Here is the work to illustrate:
35/100 = X/600
X/600 = 35/100
X*600/600 = 35*600/100
X = 21000/100
X = 210
The work above shows the long way to explain how to calculate 35 percent of 600 in order to give you a foundation and better understanding of how to calculate percentage. In the future, you could use this simplified formula:
(Y * P)/100
In our problem "What is 35 percent of 600?", Y is 600 and P is 35:
(600 * 35)/100 = 210
And once again you see that the answer is 210.
Answer:
210 kids
Step-by-step explanation:
So the formula is basically part over whole is equal to x/100%
So for here it would be x/600 = 35/100
Solve that and you will get 210
The area of a square root is 2.25m2. what is the length of each side of the square?
Show work pls, thank you.
Answer:
1.5 m
Step-by-step explanation:
Area = length * width
or we can say
Area = side1*side2
since they are the same we can say
Area = side * side
which also means area = side^2
so we have the area and we want the side, we need the inverse operation for squaring something. the inverse of squaring something is square rooting
so
sqrt(Area) = side
so
side = sqrt(2.25)
= 1.5 m

Bots have answered this for the past two times but I still need help. The question is below.
Answer:
a. False
b. True
c. True
d. I think it's true
e. False
Step-by-step explanation:
a. The unit rate is 19.75 gallons per minute
b. It is true because when x=0 y is also equal to 0, therefore it passes through the origin
c. 19.75 is about 20, and 20 multiplied by 5 is 100
d. Like I said before I don't know but I hope you get it correct ._.
e. When x=8 the equation would be 19.75*8 which is equal to 158 not 150

Sandy works at a clothing store. She makes $8 per hour plus earns 10% commission on her sales. She worked 70 hours over the last two weeks and had a total of $1,612 in sales before taxes.
Which of the following is closest to how much she will earn in hourly wages and commission for those two weeks?
A.
$721
B.
$560
C.
$161
D.
$217
Answer:
A
Step-by-step explanation:
First, I'm going to work out the hourly wages for the 2 weeks.
$8 x 70hours = $560
(8 x 7 = 56 x 10 = 560)
Next, work out the commision.
10% of $1612
1612 ÷ 10 = 161.2
Finally, add together both the hourly wages and commision.
161.2 + 560 = 721.2
Round it down to a whole number.
721 , Add on the dollar sign.
It's answer A, $721.

Answer:
x = 5[tex]\frac{1}{4}[/tex]
Step-by-step explanation:
5(x - 3[tex]\frac{3}{4}[/tex] ) = 7[tex]\frac{1}{2}[/tex]
Use distributive property
5x - 18[tex]\frac{3}{4}[/tex] = 7[tex]\frac{1}{2}[/tex]
Add 18[tex]\frac{3}{4}[/tex] to both sides
5x = 26[tex]\frac{1}{4}[/tex]
Divide both sides by 5
x = 5[tex]\frac{1}{4}[/tex]
You mix 23.385 grams of sugar and 12.873 grams of baking soda in a glass container for an experiment. You place the container on a scale to find that the total mass is 104.2 grams. What is the mass of the container
The mass of the container is 67.942 grams.
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that amount of sugar is 23.385 grams, the amount of soda is 12.873 and the total mass is 104.2 grams.
The weight of the container will be calculated as below:-
Total weight of sugar and sods = 23.385+12.873=36.258
Weight of container = 104.2-36.258=67.942
Weight of container = 67.942 grams
Therefore, the mass of the container is 67.942 grams.

A phone company advertises a new plan in which the customer pays a fixed amount of $ 25 per month for unlimited calls in the country and $ 0.10 per minute for international calls . If a customer paid 120 dollars , how many international minutes did they use ?
Answer: The answer would be 950 international minutes. Only if assuming that this is in one month since the question doesn't give much detail.
Step-by-step explanation:
X would be used to represent the number of months.
25+0.10x=120
0.10x=95
950 international minutes used
Answer:
950
Step-by-step explanation:
An equation to model this scenario would be: y = 0.1x + 25
y would mean the amount of money paid depending on x, which is the number of minutes.
In this problem, we know the amount of money. So we know y is 120.
We can then put 120 into the equation to find x.
120 = 0.1x +25
95 = 0.1x
x = 950
Therefore, x is 950.

11.50 + 1.15x = 12.65
11.50 - 11.50 + 1.15x = 12.65 - 11.50
➗ 1.15x = 1.15 ➗ what does x equal? Please explain in great detail how you figured this out also replace the = with the proper inequality sign and explain how you did that as well.
Answer: the answer is x= 1
Step-by-step explanation:
So we are dealing with 11.50 - 11.50 + 1.15x = 12.65 - 11.50
our first step is Simplify both sides of the equation so:
11.5 + -11.50 + 1.15x = 12.65 + -11.50 turns into:
(1.15x) + (11.5+ -11.5)= (12.65 + -11.5)
**we know 11.5 + -11.5 will cancel each other since they are opposite**
so it will be 1.15x= 1.15
now the very last step is to divide 1.15x on both sides which gives us 1
