Answer:
C= 38 in Approx
A=113 in^2 Aprprox
Step-by-step explanation:
Given data
radius= 6 ft
Circumference, C=2πr
substitute
C=2*3.142*6
C=37.704 in
Area A= πr^2
substitute
A=3.142*6^2
A=3.142*36
A=113.112 in^2
Which of the following equations is equivalent to 2x+7 = 27
Answer: C
Step-by-step explanation: The answer is C because x is equivalent to 10 in both problems. X is equal to 10 in the problem 2x + 7 =27 because 2 x 10 = 20 + 7 = 27. X is also equal to 10 in the problem 5x - 15 = 35 because 5 x 10 = 50 - 15 = 35. This means the answer is C.

Write an equation of the line (0,2) and (3,3) in slope intercept form
Answer:
y = 1/3x + 2
Step-by-step explanation:
slope formula: (y₂ - y₁) / (x₂ - x₁)
(0, 2) & (3, 3)
Plug the values in.
(3 - 2) / (3 - 0)
Simplify the parentheses.
1/3
This fraction is fully simplified.
Your basic slope intercept form equation is: y = mx + b.
m is the slope, which is 1/3.
y = 1/3x + b
b is the y-intercept, which is y-value when x = 0.
From one of the points given, we can see that the y-intercept is 2.
Therefore, your equation is: y = 1/3x + 2
Check your answer with the other point.
3 = 1/3(3) + 2
3 = 1 + 2
3 = 3
Your equation is correct!
Hope this helps!

A company makes steel rods shaped like cylinders. Each rod has a diameter of 8 centimeters and a height of 20 centimeters. If the company used 28,134.4 cm3 of steel, how many rods did it make?
Answer:
1,172.3 cm³
Step-by-step explanation:
Find the volume of one rod, then divide the total volume of steel used by the volume of one rod. The volume of one rod is
V = (πd²/4)h
d = 4 cm
h = 20 cm
Plugin the numbers and get V in cm³, then divide the given total volume of 28,134.4 cm³ by V. If the result is not an integer, then round down.
Add
20 + 4 = 24
Then
28,134.4 ÷ 24 = 1172.26
Rounded to the nearest 0.1 or the Tenths Place = 1,172.3
Therefore, 1,172.3 rods will be made per hour.
y= 2/3x what is the slope
Answer:
the slope is −3 .
Answer:
2/3 (fact checking...)
Step-by-step explanation:
this is a problem constructed in Slope-Intercept form, the slope is the angle that the line plotted is at.
The intercept, aka the y-intercept is where the line crosses on the y axis, in this case since y is just y and not changed, the line crosses at 0 on the y coordinate.
The slope is 2/3 because when plotted, the line will cross the point on graph at the location (x,y) 2,3 as its nearest whole set of numbered coordinates to 0,0 along said line

The scale of a room in a blueprint is 5 in.: 9 ft. A wall in the same blueprint is 30 in. Complete the table.
Blueprint length (in.) 5

30
Actual length (ft)
9
How long is the actual wall?
The actual wall is
feet long
A window in the room has an actual width of 4.5 feet. Find the width of the window in the blueprint.
The width of the window in the blueprint is
in.
Answer:
54 feets
2.5 inches
Step-by-step explanation:
Given that:
Scale model:
5 in : 9ft
If 5 in = 9 ft
Hence, 1 in on the blue print equals
5 in = 9 ft
1 in = x
Cross multiply
5x = 9
x = 9/5 feets
Hence, 1 inches on the blueprint equals 9/5 feets actual
Blueprint length (in.) ___ Actual length (ft)
5 _________ 9
10 ________ 18
15 ________ 27
20 _______ 36
25 _______ 45
30 _______ 54
Hence ;
5 * 9/5 = 9 feets
10 * 9/5 = 18 feets
15 * 9/5 = 27 feets
20 * 9/5 = 36 feets
25 * 9/5 = 45 feets
30 * 9/5 = 54 feets
Window with actual width of 4.5 feets
Width of window in blue print :
Actual width ÷ 9/5
Actual width = 4.5 = 4 1/2 = 9/2
9/2 * 5 /9
= 5 /2
= 2 1/2 inches = 2.5 inches
34. A vessel is in the the form of a hemispherical bowl mounted by a hollow cylinder The diameter
of the sphere is 3.5 m and the height of the cylinder is 2 m. Find the volume of vessel
Answer:
[tex]V=20.85\ m^3[/tex]
Step-by-step explanation:
Given that,
The vessel is in the the form of a hemispherical bowl mounted by a hollow cylinder.
The diameter of the sphere is 3.5 m.
The height of the cylinder is 2 m
Height of the cylinder = Height of bowl− Radius of hemisphere
= 2 - (3.5/2)
= 0.25 m
The volume of the vessel is given by :
V = volume of hemispherical bowl + volume of cylinder
So,
[tex]V=\dfrac{2}{3}\pi r^3+\pi r^2 h\\\\V=\dfrac{2}{3}\times \dfrac{22}{7}\times (\dfrac{3.5}{2})^3+\dfrac{22}{7}\times (3.5)^2\times 0.25\\\\V=20.85\ m^3[/tex]
So, the volume of the vessel is [tex]20.85\ m^3[/tex].

For questions 1-4, find the distance between points A and B. Round your solutions to the nearest tenth when necessary.
Answer:
1. AB= 8.94,
2. AB= 7.28
3. AB= 16.4
4. AB= 19.21
Step-by-step explanation:
This is fun! Well you have to find the (1,4) (or point e) point and count the distance to the other points point a and point b.
4 units from a to e and 8 b to e
a² + b² = c²
8² + 4² = c²
64 +16 = c
√80 = √c²
8.94 = c
It dose not matter which units you plug in for a and b but c has to be the long side of the triangle/ hypotonuse.
Follow the same steps for the rest of the problems.

for each sequence find the first 4 terms and the tenth term
a) n squared +3
b) 2n squared
Answer:
Step-by-step explanation:
Given that:
a) n³
The first 4 terms are;
let assume n = 1
1³ = 1
if n = 2
2³ = 8
if n= 3
3³ = 27
if n = 4
4³ = 64
So, the sequence is 1, 8, 27, 64
The tenth term of this sequence is: 10³ = 1000
b)
2n²
if the first term is 1
then 2(1)² = 2
if n = 2
2(2)² = 8
if n = 3
2(3)² = 18
if n = 4
2(4)² = 32
So, the sequence is 1, 8, 18, 32
The tenth term will be 2(10)² = 200

Write an expression that models the situation. Ruben has 83 red peppers and g green peppers. What is the total amount of peppers?
Answer:
83 + g
Step-by-step explanation:
The total amount of peppers is calculated as:
Number of red peppers + Number of green peppers
Ruben has 83 red peppers and g green peppers.
The total amount of peppers =
83 + g
Therefore, the expression that models the situation =
83 + g
