This cylinder has a radius of 4 feet and a volume of 2087 cubic feet.
What is the height of the cylinder?
Answer:
h = 41.52 feet
Step-by-step explanation:
The volume is π•radius²•height:
π•4²•h = 2087
16πh = 2087
h = 2087/16π
h ≈ 41.52 feet
What is the midpoint of segment AB?
Answer:
(-1, -3.5)
Step-by-step explanation:
Use the midpoint formula by finding the points of A and B.
A = (-5, -4)
B = (3, -3)
Add the x-values of both coordinates to get the following:
[tex]3_{1} + -5_{2} = -2\\-2/2 = -1[/tex]
Midpoint = (-1, y)
Now we find the y-value by doing the same as we did to the x-coordinates of A and B.
[tex]-3_{1} + -4_{2} = -7\\-7/2 = -3.5[/tex]
Midpoint = (-1, -3.5)
The length of a rectangle is three times its breadth if the breadth is decreased by 2 m and breadth increased by 4 m the area of the rectangle is decreased by 1/3
a) form a quadratic equation
Answer:
Let the breadth is x, then the length is 3x.
The area is:
A = lw = 3x*x = 3x²The breadth is decreased by 2 m:
w = x - 2The length is increased by 4m:
l = 3x + 4The area is now:
(x - 2)(3x + 4) = 3x² - 1/3(3x²)3x² + 4x - 6x - 8 = 2x²x² - 2x - 8 = 0x² - 2x + 1 = 9(x - 1)² = 3²x - 1 = 3x = 4The breadth was 4 m and the length 12 m

Step-by-step explanation:
Hello!
First of all you have to understand the order of operations.
PEMDAS
Parenthesis, Exponent, Multiplication/Divison, Addition, Subtraction.
From this you can see that we first have to deal with the exponent, then multiplication, then the addition.
So we get 2+9-(-1)
The 9 is from -3^2
2+9+1

a cake recipe calls for 2 1/2 cups of sugar. A caterer had 37 3/4 cups of sugar on hand. how many cakes can he make?
Answer:
Step-by-step explanation:
Set this up as a ratio of number of cakes to cups of sugar, C:S
Then the ratio given is 1:2.5 which says 1 cake takes 2.5 cups of sugar. We want to know how many cakes, x, will be made with 37.75 ups of flour:
[tex]\frac{1}{2.5}=\frac{x}{37.75}[/tex] and cross multiply to solve:
2.5x = 37.75 so
x = 15.1 cakes or just 15 cakes (cuz you can't make one-tenth of a cake!)

600 becomes 720 in 2 years when the interest is simple if the rate of interest is increased by 2% then what will be the total amount.
Hi
So: 720 -600 = 120
120 for two years makes 120/2 = 60 in a year .
60 from 600 is 600/60 = 10
Interest is 10 %
If interest in 2% more, then it's 12%.
I'm sure you can count 12% simple interest for two years, so I let you try.
good luck.

y= -3x+4
x | -8 -4 0 4 8
y | 28 ? ? ? ?
Answer:
see below
Step-by-step explanation:
y= -3x+4
Let x = -4
y= -3(-4) +4 = 12 +4 = 16
Let x = -0
y= -3(0) +4 = 0 +4 = 4
Let x = 4
y= -3(4) +4 = -12 +4 = -8
Let x = 8
y= -3(8) +4 = -24 +4 = -20
Mathematical Connections The triangle shown
is isosceles. Find the length of each side and the
perimeter.
#14
--------------------------------------
If a triangle is isosceles, it means that two sides have equal measures.The perimeter of a polygon is the sum of the lengths of all its sides.--------------------------------------
Value of n:
The two legs have the same length.One is [tex]5n - 17[/tex], and the other is [tex]2n + 1[/tex], thus:[tex]5n - 17 = 2n + 1[/tex]
[tex]5n - 2n = 1 + 17[/tex]
[tex]3n = 18[/tex]
[tex]n = \frac{18}{3}[/tex]
[tex]n = 6[/tex]
--------------------------------------
Lengths:
The lengths are given as functions of n, since n = 6:
[tex]5n - 17 = 5(6) - 17 = 30 - 17 = 13[/tex][tex]2n + 1 = 2(6) + 1 = 12 + 1 = 13[/tex][tex]n = 6[/tex]The length of the sides are: 13 cm, 13 cm and 6 cm.
--------------------------------------
Perimeter:
The perimeter is the sum of the lengths of all sides, so: 13 + 13 + 6 = 32 cm.

Where m is the slope of the line and c is the y-intercept of the line.
Damian is monitoring the temperature of the swimming pool. It is currently 86.8° and cooling 0.5° per minute. Then the equation will be
y = 86.8 - 0.5x
The number of minutes when the temperature of the swimming pool be 80.8° will be
80.8 = 86.8 - 0.5x
0.5x = 6
x = 12
The number of minutes when the temperature of the swimming pool is 80.8° will be 12 minutes.

Write an equation that represents the line.
Use exact numbers
Answer:
y = 5/6x + 8/3
Step-by-step explanation:
y = mx + b (m is the slope, b is the y-intercept)
(-2, 1) (4, 6)
m = change in y / change in x
m = 5/6
y = 5/6x + b
Plugging in (4, 6):
6 = 5/6(4) + b
6 = 20/6 + b
36/6 = 20/6 + b
36/6 - 20/6 = b
b = 16/6
b = 8/3
y = 5/6x + 8/3

George has a storage unit already occupied by a large container that is the same height of the whole unit. How much space is left for storage?
Answer:
945 m³
Step-by-step explanation:
Space left for storage = Volume of storage unit - volume of the container
Storage unit:
length = l = 15.3 m
Height = h = 10 m
Width = w = 7 m
Volume of storage unit = l * w *h
= 15.3 *7* 10
= 1071 m³
Container:
length = l =4.2 m
Height = h = 10 m
Width = w = 3 m
Volume of container = l * w *h
= 4.2 *3* 10
= 126 m³
Space left = 1071 - 126 = 945 m³
