Hey there! I'm happy to help!
First, let's find the area of the circle of the first cylinder. To do this, we square the radius and multiply by 3.14.
3²=9
9×3.14=28.26
Now we multiply by our height of 49 cm to see how much water there is.
28.26×49=1384.74
Now, let's find the area of the circle of the 7 cm cylinder.
7²=49
49×3.14=153.86
Now, we will take our liquid amount (volume) and divide by this circle amount (base) to find the number of centimeters of height of the water column.
1384.74÷153.86=9
So, the height of our water column will be 9 cm.
Have a wonderful day and keep on learning! :D
Answer:
fast multiply 5 by 39 to get the total age of the five people now as you are told those per 5 so imagine the six person being you if you enter you're going to add to their ages so they mean is going to be for six people so take the six people x their mean age now we have two different total ages for the five people and for the six people subtract the total age of the 5 from the 6th total ages to get the age of the person who entered the room if you don't understand please ask me and be willing to help

Answer:
Can't really show a graph but I'll explain how to:
Step-by-step explanation:
Plot the point (0,-2) since -2 is the y=intercept. After, just count-down 1 unit and count 5 units to the right. I hoped this helped!
Answer: the equations are
0.02x + 0.07y = 156
y = 300 + x
Step-by-step explanation:
Let x represent the total dollar amount of phone sales that she makes.
Let y represent the the total dollar amount of computer sales that she makes.
Josiah earns a 2% commission on the total dollar amount of all phone sales he makes, and earns a 7% commission on all computer sales. She earned a total of $156 in commission. This means that
0.02x + 0.07y = 156 - - - - - - - - - - -1
Josiah had $300 more in computer sales than in phone sales. This means that
y = 300 + x
