V = 612.3
Step-by-step explanation:
d = 6
r = 3
Volume of a cylinder:
V = πr²h
V = 3.14(3²)(20)
V = 3.14(9)(20)
V = 565.2
Volume of a cone:
V = πr²(h/3)
V = 3.14(3²)(5/3)
V = 3.14(9)(5/3)
V = 47.1
Combined:
565.2 + 47.1

Aziz purchesis 4 2/8 feet of fabric he used 1/5 of fabric to make a tote bag how much fabric will aziz have left over?
Answers
Answer:
3/20
Step-by-step explanation:
Fabric left over = total fabric purchased - total fabric used to make a tote bag
total fabric used to make a tote bag = [tex]4\frac{2}{8}[/tex] × [tex]\frac{1}{5}[/tex] =
[tex]\frac{34}{8}[/tex] × [tex]\frac{1}{5}[/tex] = [tex]\frac{34}{40}[/tex]
fabric left over = 1 - 34/40
40 / 40 - 34/40 = 6 /40
To transform to the simplest form. divide both the numerator and the denominator by 2

23. Three businessmen A, B and C enter into
partnership and agree to share the total
profit in the ratio of their investments. A
invested GH¢450, B invested GH¢150
and C invested GH¢600. C received a
profit of GH¢24.70, find
i) the total profit.
ii) the profits made by A and B.
Answers
Step-by-step explanation:
A invested 450
B invested 150
C invested 600
total investment was 1200
share of A is 450/1200 = .375
share of B is 150/1200 = .125
share of C is 600/1200 = .5
C received a profit of 24.70.
that would be .5 of the total profit.
if we let x = total profit, we get .5 * x = 24.70
solve for x to get x = 24.70 / .5 = 49.40
A share of total profit = .375 * 49.4 = 18.525
B share of total profit = .125 * 49.4 = 6.175
C share of total profit .5 * 49.4 = 24.7
total profit = 49.4 as we had calculated earlier.

Graph the following exponential function given the table of
values.
Answers
Answer:
D
Step-by-step explanation:
Here, we want to select the graph of the given exponential function values
Let us take a look at the y-intercept
At the y-intercept, the value of x is 0
The y-intercept for this particular equation is 1
This mean that the y-intercept value is 1
hence, the graph will touch the y-axis at the point y = 1
looking at the graphs , only the graph D provides this, and that should be our answer

B. The constant of variation
C. The independent variable
D. The direct variation equation
Answers
Answer:
I think it B but I really don't know cause need like an example
The k in the equation represents Option B) The constant of variation
What is a constant in an equation?A constant is a value or number that never changes in expression; it's constantly the same. For example, 36 and 82 are constant because its face value is 36 and 82 respectively. Its value never changes.
Given here the equation y=kx where k is the slope and a scalar value thus it is independent of x and y and thus is a constant.
Hence, The k in the equation represents Option B) The constant of variation

The width of a rectangle is
12 cm less than the length.
The area is 64 cm2. Find the
length and width.
Answers
Answer:
Length of rectangle = 16 cm
Width of rectangle = 4 cm
Step-by-step explanation:
Given:
Area of rectangle = 64 cm²
Find:
Length and width
Computation:
Assume;
Length of rectangle = a
So,
Width of rectangle = a -12
Area of rectangle = l x b
So,
a(a-12) = 64
a² - 12a - 64 = 0
a² - (16-4)a - 64 = 0
a² - 16a+ 4a - 64 = 0
a (a-16) + 4(a-16)= 0
(a-16)(a+4) = 0
a= 16 , a = -4
So,
Length of rectangle = 16 cm
Width of rectangle = a -12
Width of rectangle = 16 -12
Width of rectangle = 4 cm

If$2500was invested 6 years ago, andtheinterestwascompoundedquar-terly,whatwastheinterestrateifthecurrentvalueis$3425?
Answers
Answer:
The interest rate was 5.24%.
Step-by-step explanation:
You can use the following formula to calculate the interest rate:
i=n*((A/P)^1/nt-1), where:
i= interest rate
n= number of times interest is compounded= 4
A=value of investment= 3425
P= principal= 2500
t=time= 6
Now, you can replace the values on the formula:
i=4*((3425/2500)^1/4*6-1)
i=4*(1.37^1/24-1)
i=4*0.0131
i=0.0524
According to this, the answer is that the interest rate was 5.24%.

All four triangular faces have an area of 12 m2.
There are two sets of opposite congruent triangular faces.
The base has an area of 30 m2.
Answers
Answer: Pyramid A: Base is rectangle with length of 10 meters and width of 20 meters.
Pyramid B: Base is square with 10 meter sides.
Heights are the same.
Step-by-step explanation: The volume of pyramid A is TWICE the volume of pyramid B.
If the height of pyramid B increases to twice the of pyramid A, (from 10m to 20m),
V of square pyramid = (10m)² * (10*2)/3 = 100m² * 20m/3 = 100m² * 6.67m = 666.67 m³
The new volume of pyramid B is EQUAL to the volume of pyramid A.
