Step-by-step explanation:
If you look at the chart you can see 20 mins and then if you go to the point of 25 which would be between ( in the middle) of 20 and 30, then you would go up to the empty point that is followed up by the 20 and 30 and as you can see you get 380, so your first answer for number 1 would be 380 gallons
The second question um looking at the chart again if you would go to 35 then go up you can see 500 is how 35 Is your answer (about 35 mins)
The last one is 15 don't know how I got it but it's 15.

How can you use the lengths in a scale drawing of an object to find the object's actual area?
A.)Find the area of the object in the scale drawing and then multiply by the reciprocal of the scale factor.
B.)Find the area of the object in the scale drawing and then multiply by the scale factor.
C.)Multiply each scale length by the scale factor and apply the object's area formula.
D.)Multiply each scale length by the reciprocal of the scale factor and apply the object's area formula.
Answers
Answer:
B
Step-by-step explanation:
To calculate actual area based on a scale drawing, take each of the original dimensions and multiply them by the scale factor to get the actual dimensions.
The value of the surface area is equal to the value of the volume. Find the value of x. Then find the surface area and volume of the cylinder. Diameter of the cylinder=7 1/5 feet, height of the cylinder=x. I also need to know how to solve it.

Answer: sa=pidh+2pir^2
v=hpir^2
d=7.2
r=7.2/2=3.6
sa=pi(7.2)(x)+2pi3.6^2
sa=7.2pix+25.92pi
V=hpir^2
V=xpi3.6^2
V=xpi12.96
SA=V so
7.2pix+25.92pi=xpi12.96
divide both sides by pi
7.2x+25.92=12.96x
minus 7.2x from both sides
25.92=5.76x

write an equation using x and y to represent the hanger.
Answers
Answer:
Step-by-step explanation:
Givens
The triangle is x
The square is y
Left side
x + 3y is the weight
Right side
4x + y is the weight.
The weights are equal because the hanger is balanced.
Balance equation
x + 3y = 4x + y Subtract x from both sides
x-x + 3y = 4x-x + y Combine
3y = 3x + y Subtract y from both sides
3y - y = 3x + y - y Combine
2y = 3x
Answer
2y = 3x
Answer:
x +3y = 4x +y
Step-by-step explanation:
A hanger diagram like this is intended to show you that the total weight on the left side is equal to the total weight on the right side.
__
left sideThe left side shows 1 triangle and 3 squares. x and y are defined as the weights of the triangle and square, respectively, so the weight on the left side can be represented as ...
x + 3y
right sideThe four triangles and 1 square on the right can have their total weight represented as ...
4x +y
balanceThe intent of the diagram is to show that the left-side weight is equal to the right-side weight. That equality can be written as ...
x +3y = 4x +y
_____
Additional comment
This problem is not asking for any sort of "solution" or relationship between x and y. We could find such a relationship by solving the equation for y:
x +2y = 4x . . . . subtract y from both sides
2y = 3x . . . . . . . subtract x from both sides
y = (3/2)x . . . . . divide by the coefficient of y
This tells you that the hanger will only be balanced if the weight of a square is half-again as much as the weight of a triangle.

use benchmarks to estimate each sum or difference 17/18 - 3/7 ((MORE IN IMAGE))
Answers
Answer:
About 1/2 should be the answer. Hope this helps!
The required, based on the benchmark estimation, the difference 17/18 - 3/7 is approximately 0. Option C is correct.
To estimate the difference between 17/18 - 3/7 using benchmarks, we can round the fractions to the nearest benchmark values.
For 17/18, the nearest benchmark fractions are 16/18 and 1/2.For 3/7, the nearest benchmark fractions are 2/7 and 1/2.Let's estimate the difference using these benchmark values:
Using 16/18 - 2/7:
16/18 is close to 1/2 (9/18) and 2/7 is close to 2/7. Subtracting these fractions gives us:
1/2 - 2/7 = 7/14 - 4/14 = 3/14
Using 1/2 - 1/2:
1/2 - 1/2 = 0
Therefore, based on the benchmark estimation, the difference 17/18 - 3/7 is approximately 0.
