Step-by-step explanation:
42 minus 31 is 11
so 11/42 = /100
Answer:
11/42 = x/100
Step-by-step explanation:
42 students and 31 are girls
42 -31 = 11 that is the number of boys
boys / total = x/100 to find the percent
11/42 = x/100
Which of the following is not a rate?
A.doing 45 crunches in 1 minute
B.paying $3.15 for 1 gallon of gas
C.folding 6 loads of laundry in 3 days
D.walking 4 miles in 1 hour
Answer:
C
Step-by-step explanation:
Usually rate is determined as a distance over time, where the time is a unit. In other words, we have "1" of the time (for example, 1 hour, 1 second, 1 gallon, etc).
Look at each answer choice:
A: doing 45 crunches in 1 minute
This is definitely a rate because the time (1 minute) is a unit.
B: paying $3.15 for 1 gallon of gas
Again, this is considered a rate because you're paying $3.15 per gallon.
C: folding 6 loads of laundry in 3 days
We can see this isn't a rate because the time is 3 days, not 1. So C is the answer.
D: walking 4 miles in 1 hour
This is a rate because our time is 1 hour.
The answer is C.
Answer:
C.folding 6 loads of laundry in 3 days
Step-by-step explanation:
folding 6 loads of laundry in 3 days means, 6/3 = 2 loads of laundry per day.
Rate is 2 per day

Enter the equation of the circle described below.
Center (5,2), radius = 3
Answer:
[tex](x-5)^2+(y-2)^2=9\\[/tex]
Step-by-step explanation:
So, you basically want the equation of the circle.
Given:
Center(C): [tex]C(5, 2)[/tex]
[tex]r=3[/tex]
The equation of circle is:
[tex](x-h)^2+(y-k)^2=r^2\\[/tex]
Where, [tex](h, k)[/tex] represents the center point and [tex]r[/tex] is the radius of the circle.
Plotting the values in the equation:
[tex](x-5)^2+(y-2)^2=3^2\\[/tex]
[tex](x-5)^2+(y-2)^2=9\\[/tex]
This is the equation of the circle of center (5, 2) and radius 3.
Answer:

carbon monoxide is a gas that is 43% carbon. carbon dioxide only 27% carbon. suppose that the environmental protection agency (epa) analyzes exhaust from cars, a mixture of carbon monoxide and carbon dioxide. if the epa finds that a 1600 mg sample of exhaust gas has 32% carbon, how many mg of the sample were carbon monoxide, and how many were carbon dioxide?
Answer:
500 mg Carbon Monoxide
1100 mg Carbon Dioxide
Step-by-step explanation:
Weight of total sample = 1600 mg
Percentage of Carbon in Carbon Monoxide = 43%
Percentage of Carbon in Carbon Dioxide = 27%
Percentage of carbon in Mixture = 32%
Let amount of Carbon Monoxide = [tex]x[/tex] mg
Amount of Carbon Dioxide in mixture = (1600-[tex]x[/tex]) mg
Amount of carbon in [tex]x[/tex] mg of Carbon Monoxide =
[tex]x \times 43\%\\\Rightarrow x \times \frac{43}{100} ...... (1)[/tex]
Amount of carbon in (1600-[tex]x[/tex]) mg of Carbon Monoxide =
[tex](1600-x) \times 27\%\\\Rightarrow (1600-x) \times \frac{27}{100}......(2)[/tex]
We know that the sample of 1600 mg contains carbon because of Carbon Monoxide and Carbon Dioxide present in it.
Adding (1) and (2) and equating to 32% of 1600 mg:
[tex]x \times \dfrac{43}{100} + (1600-x) \times \dfrac{27}{100} = 1600 \times \dfrac{32}{100}\\\Rightarrow x \times (43-27) = 1600 \times (32-27)\\\Rightarrow 16x = 1600 \times 5\\\Rightarrow x =500[/tex]
Amount of Carbon Monoxide in sample,[tex]x[/tex] = 500 mg
Amount of Carbon Dioxide in sample = (1600 - [tex]x[/tex]) = (1600 - 500) = 1100 mg
Hence, answer is
500 mg Carbon Monoxide
1100 mg Carbon Dioxide
The school's football team has 228th graders. If this is 40% of the team, how many total players are on the team?
570
hope this helps!
Answer:
55 total students
Step-by-step explanation:
Change the percent to a decimal.
40% = 0.4
Divide the number of 8th graders by the decimal to find the total players on the team.
22/0.4 = 55
The total number of students is 55.
The graph shows the parent function f(x)=2(0.5)
Which graph represents the function g(x) = 2(0.5)x - 1?
The answer is the top one to the right
The graph that represents the function g(x) = 2(0.5)ˣ -1 is given.
What is graph?In mathematics, a graph is a visual representation or diagram that shows facts or values in an ordered way.
The relationships between two or more items are frequently represented by the points on a graph.
Given expression,
g(x) = 2(0.5)ˣ -1
To draw the graph take x = 0, 1,2, -1 , -2 and so on .
And draw these numbers in the graph.
Take x=0
g(0) = 1
the point is (0,1)
And now , take x = 1
g(1) = 0
the point is (1,0)
Take x =-1
g(-1) = 3
The point is (-1,3)
Therefore, the graph is given in the image.

In one day, a yoga instructor teaches 3 classes in the morning and 4 classes in the afternoon. The length of each class is m minutes.
Which expression represents the total number of minutes the yoga instructor teaches in one day?
OA 7m
OB 7+ m
ОС. 10
D10 + m
Answer:
B. 7m
Step-by-step explanation:
She has 7 classes a day (3+4), and each takes the same number of minutes. If m stands for minutes per class, you can find the total minutes per day by multiplying 7 by m. Therefore the answer is 7m.
Example: Let's say a class takes 30 minutes, you would put 30 in the place of m, 7x30=210, so she would be teaching 210 minutes of yoga class each day.

Manny has two part-time jobs. One job pays $10/hour and the other pays $16/hour. ...
Answer:
x = 0
Step-by-step explanation:
The equation of a line is shown by using the formula y = mx+b
But, in special cases like this one, where the line is completely vertical then we use the same formula but we just adjust it.
When a line is completely straight up and down the equation is x = #
Since the line is on the y-axis (or has a x value of zero) the equation is x = 0.
There is no y in this equation because the line is hitting all values of y (which means y is ∞) with only 1 value of x. (As opposed to most equations where one or multiple values of y with one value of x or vise-versa.)
The base of a prism is a right triangle with legs measuring 14 inches and 18 yards. If the height of the prism is 20 yards, find its volume in cubic yards
Answer:
2520 in³
Step-by-step explanation:
The volume of a prism is calculated as
V = Ah ( A is the area of the base and h the height )
A = [tex]\frac{1}{2}[/tex] bh( b is the base and h the height ), thus
A = [tex]\frac{1}{2}[/tex] × 14 × 18 = 7 × 18 = 126 in²
V = 126 × 20 = 2520 in³

Write the slope-intercept form of the equation for the line.
A.)y=3x-1
B.)y=1/3x+1
C.)y=1/3x-1
D.)y=-3x-1
Answer:
A.) y=3x-1
Step-by-step explanation:
Point-slope form can be shown using the equation: y = mx+b
In this case, m is slope, and b is the y-intercept.
Slope in this graph can be found by finding the rise over the run, or the number of blocks the line moves vertically over the number of blocks the line moves horizontally. The line moves at a rate of 3 blocks up for every 1 block to the right, or 3/1. That means that the slope is 3.
The y-intercept is wherever the line crosses the y-intercept, or wherever x equals 0. This happens at y = -1.
If you plug the slope (3) and the y-intercept (-1) into the equation y = mx+b, you get y = 3x-1.
