In the drawing, s>t. Which statement about the volumes of the two cylinders is true?
a.-The volume of the right-hand cylinder is less than the volume of the left-hand cylinder.
b.-The volume of the right-hand cylinder is greater than the volume of the left-hand cylinder.
c.-The two volumes are equal.
d.-There is not enough information. The actual measurements are not given.
Answer: A
Step-by-step explanation:
The correct statement about the volumes of the two cylinders is,
⇒ The volume of the right-hand cylinder is less than the volume of the left-hand cylinder.
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
In the drawing,
s > t
Where, 's' is radius of left hand side cylinder and 't' is radius of right hand side cylinder.
We know that;
Volume of cylinder = πr²h
Hence, Volume is directly proportional to radius.
Larger the radius gives large Volume.
Hence, WE get;
The volume of the right-hand cylinder is less than the volume of the left-hand cylinder.
Thus, The correct statement about the volumes of the two cylinders is,
⇒ The volume of the right-hand cylinder is less than the volume of the left-hand cylinder.

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.

Given the linear equation 2x + 3y = 9. Determine the slope and y-intercept of the line. ...

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.)

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 radius of a the head of a snowman is about 2/3 times the radius of the base of the snowman. If the surface area of the base of the snowman is 1800 square centimeters, what is the approximate surface area of the snowman's head?
Answer:
The approximate surface area of the snowman's head is 125.33 sq.cm.
Step-by-step explanation:
Formula of surface area =[tex]4 \pi r^2[/tex]
We are given that The surface area of the base of the snowman is 1800 square centimetres
So,[tex]4 \pi r^2 =1800[/tex]
[tex]4 \times \frac{22}{7} \times r^2 = 1800 \\r^2 = \frac{1800 \times 7}{22 \times 4}\\r=\sqrt{\frac{1800 \times 7}{22 \times 4}}\\r=11.96[/tex]
The radius of a the head of a snowman is about 2/3 times the radius of the base of the snowman
So, Radius of head = [tex]\frac{2}{3} \times 11.96 =7.97[/tex]
Surface area of snowman's head=[tex]4 \times \frac{22}{7} \times 9.97=125.33 cm^2[/tex]
Hence the approximate surface area of the snowman's head is 125.33 sq.cm.
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.

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
