A cylinder has a total area of 3.41946cm2 and a diameter of 0.66cm. What is its height?
Answers
Total surface Area(A) = 2pi*r(r+h)
Diameter D= 2r
r=0.66/2=0.33cm
A=3.41946
3.41946=2*3.143*0.33(0.33+h)
3.41946=2.0744(0.33+h)
3.41946/2.0744=(0.33+h)
1.6484=0.33+h
1.6484-0.33=h
h=1.3184cm
Step-by-step explanation: Total surface area is different from area around the cylinder.

A. The correlation coefficient is approximately 0.96
C. The correlation coefficient is approximately 0.33.
E. The line of best fit cannot be used to make accurate predictions from the data
What is correlation?Correlation of two pairs of data values tells about the degree of movement(along or opposite) that can occur in one of the data values when other data value is increased or decreased respectively.
The correlation coefficient is the degree of association between two quantities in terms of linear relation.
The range of correlation coefficient is -1 to 1
The correlation is -1, then that means as the one quantity increases, the other quantity decreases (linearly)
We can conclude that the correlation coefficient is approximately 0.96
The correlation coefficient is approximately 0.33.
The line of best fit can't be used to make accurate predictions from the data

Brent spends $ 420 on his monthly bills. Of this amount, 15 % is for utilities, 1/5 is for Internet service, and 1/7 is for phone service. If the rest of the total amount is for food, how much money does Brent have for food?
Answers
Answer: $213
Step-by-step explanation:
First find out how much is spent on the other things:
Utilities
= 15% * 420
= $63
Internet services
= 1/5 * 420
= $84
Phone service
= 1/7 * 420
= $60
The amount left for food is therefore:
= 420 - money spent on other things
= 420 - 63 - 84 - 60
= $213

A bag contains 49 coins consisting of quarters and dimes. There are 2.5 times as many quarters as there are dimes in the bag. Write a system of equations that models this situation. How many dimes are in the bag?
pls write step by step so that I can understand :)
Answers
Answer:
Dimes = 35
Quarters = 14
Step-by-step explanation:
Let
quarters = q
Dimes = d
Total coins = 49
There are 2.5 times as many quarters as there are dimes in the bag
Dimes = 2.5q
Quarters + Dimes = Total
q + 2.5q = 49
3.5q = 49
q = 49/3.5
q = 14
d = 2.5q
= 2.5 * 14
= 35
d = 35
Therefore,
Dimes = 35
Quarters = 14
Answer:
The system of equations that models this equation area:
d + q = 49
q = 2.5d

The soil in Sean's backyard is made up of 45% sand. If he has 1000 lbs of soil in his yard, how many pounds of sand are there?
Answers
Answer: 450 lbs
Step-by-step explanation:
45/100 is 45%
Since there are 1000 lbs we multiply 45/100 by 10, giving us 450/1000
Therefore 45% of 1,000 is 450
450 pounds of sand is present in the soil.
What is percentage?
'A percentage is a number or ratio expressed as a fraction of 100. A percentage is a dimensionless number, that is, it has no unit of measurement.'
Total weight of soil in Sean's backyard = 1000 pounds
Percentage of sand in the soil = [tex]\frac{45}{100}[/tex]
Total amount of sand in the soil = ( [tex]\frac{45}{100}[/tex] × 1000 ) lbs
= 450 lbs
Hence, we can conclude, 450 pounds of sand is present in the soil in Sean's backyard.

When Carla is picking, we can do:4/3 which is 1 and 1/3, which is her apple bushel picking per hour. For her pears, she picks them at 2 bushels of pears per hour.
Since Shawn picks her apples quicker per hour, and her pears quicker per hour, Shawn picks at a faster fruit pace.

Please help! Ralph buys a computer for $675. The sales tax rate is 6%. How much did Ralph pay for the computer?
Answers
Answer:
$715.50 my dudeeee
Step-by-step explanation:
..........
Ralph pays a total of $715.5 for the computer including the sales tax amount.
What is Percentage?Percentage is defined as the part of a number in a whole of 100. % is the symbol used to denote the percentage.
Percentage of a number in a whole can be calculated by dividing that number with the whole and then multiply to 100.
Actual price of the computer = $675
Sales tax rate = 6%
Ralph has to pay the actual price and in addition the sales tax to buy the computer.
Amount of sales tax = 6% × 675
= (6/100) × 675
= 0.06 × 675
= $40.5
Ralph should add $40.5 to the actual price.
Total payment made for buying the computer = $675 + $40.5
= $715.5
Hence Ralph pays a total amount of $715.5 for the computer.

Answer:
an ordered pair
the point where all the lines intersect (which is located by the ordered pair above)
No solutions (in case for example you have parallel lines, so no point there they intersect)
Infinitely Many Solutions (this is when for example you have one single equation, each point of the line is a solution and there are infinite points)
Step-by-step explanation:
basically a "system" means finding a solution that is valid for each equation, like a logical AND
so in this case it means finding a point that lies on each line, and that point can only exists (the intersection of those lines) or not exist (they are parallel)
if the system is made of one single linear equation then you have infinite solutions
