Answer:
116.6
Step-by-step explanation:
Volume = ⅓ × area of base ×height. We don't have the area of base, we need to find it.
Perimeter (4×Length) = 16.9 cm
Length = 16.9÷4 = 4.225 cm
Area = L² = 4.225² =
Volume of pyramid = 1/3 × 4.225² × 19.6 = 116.624 = 116.6 cm³

Find the value of c that will make the following two expressions equivalent to 4!!
The answer is 4, Our teacher gave us the answer but I need the work to show how she got it.
2a+10b-8-2(4a-6) and -6a+10b+c
Answer:
see below
Step-by-step explanation:
We are given 2 equations:
[tex]2a+10b-8-2(4a-6)\\-6a+10b+c[/tex]
We are told to find c to make them equivalent, so we can make them equal to each other:
2a+10b-8-2(4a-6)=-6a+10b+c
To find c, we have to isolate it, here are the steps:
2a+10b-8-2(4a-6)=-6a+10b+c
subtract 10b from both sides
2a-8-2(4a-6)=-6a+c
rearrange left side
2a-2(4a-6)-8=-6a+c
distribute the positive 2 to the terms in parenthesis
2a-(8a-12)-8=-6a+c
distribute -1 to the terms in parenthesis
2a-8a+12-8=-6a+c
simplify
-6a+4=-6a+c
add -6a to both sides
4=c

The owners of a company are hosting a party for its 453 employees. They want to order sandwich platters that each feed 24 people. What is the LEAST number of platters the owners should order if they want to have enough sandwiches to feed all of the employees?
Answer:
19 Platters
Step-by-step explanation:
453 ÷ 24 = 18.875
Rounded to the nearest whole number = 19
∴ It would take at least 19 platters
Proof:
19×24=456
Which is more that enough
The diameter of the cracker shown is 35 millimeters.
Which measurement is closest to the area of the cracker in square millimeters?
A 781.751 mm²781.751 mm²
B 109.9 mm²109.9 mm²
C 961.625 mm²961.625 mm²
D 54.95 mm²
C
Step-by-step explanation:
Diameter = 35 mm
Radius = 35 ÷ 2 = 17.5 mm
Area = pi × r² = pi × 17.5² = 962.112
The closest one is C

Answer: 6
Simple Explanation:
To find 75% of 8, just multiply 8 by 0.75 (which is the same as 75%).
8 x 0.75 = 6
....................
answer this question.
Answer:
40
Step-by-step explanation:
70% of something is 28.
We'll use the variable x to hold our value. 70% can be written as 0.7. Rewriting our equation, we get:
0.7 * x = 28.
Lets divide 0.7 over. Our new equation is:
x = 28 / 0.7.
You get that x = 40.
70% of 40 = 28.
Answer:
The answer is 40
Step-by-step explanation:
Sorry I can't really give a good explaination

Answer:20.7 units²
Step-by-step explanation: volume of a rectangular prism is L×W×H
therefore 82.8=L×W×the height which is 4 units so if u do 4×L×W you get 4LW which is the volume
(4LW=82.8) now divide 82.8 by 4LW to get the value of LW. The value of LW is an area of one of the bases because area is L×W which is basically LW
hope you understand all the best

Answer:
1. slope = 12
y-intercept = 1/3
2.slope = 1/4
y-intercept= -12
3.slope = 3
y-intercept = 2
Step-by-step explanation:
When you get an equation for a graph, the co-efficient infront of the x (The number by the x) is the slope.
The equation for the y-intercept:
When solving for y-intercept, you replace y in the equation with 0 and make x the subject.
Example:
y = 12x - 4
0=12x - 4
-12x = -4
divide both sides by negative 12 since we want only positive x
[tex]\frac{-12x}{-12} =\frac{-4}{-12}[/tex]
x = [tex]\frac{1}{3}[/tex]
Therefore, the y-intercept = 1/3
Alex painted 178 ft2 of his 1/3 apartment's walls with gallon of paint. He has 2 gallons of paint in all. If he wants to cover 1,000 f2 of his apartment, does he have enough paint? Complete a true statement.
2 gallons of paint will cover
A. 968
B. 996
C. 1,068
f2 and Alex needs to cover 1,000 f2 so he
D. will
E. will not
have enough paint.
Answer:
Step-by-step explanation:1 gallon of paint paints 1/3 of the house and he had already painted 1/3 of the house with 1 gallon of paint. so the left is 2/3 of the house. and 2 gallon of paint paints 2/3 of the house so,2/3=2/3 which means D. he will cover 1,000 f2 of his apartment.
You and a friend race each other. You give your friend a 50-foot head start. The distance y (in feet) your friend runs after x seconds is represented by the linear function y=14x+50 . The table shows the distances you run.
Time (seconds) x : 2, 4, 6, 8
Distinct (feet) y : 38, 76, 114, 152
A: write a linear equation that relates to your speed?
B: How long will it take for you to catch your friend?
A. (76-38)/4-2=19 --> m=19
finding b:
y=19x+b
38=19(2)+b
38-38=0
b=0
Linear equation: y=19x
B.
Set the two equation equal to each:
19x=14x+50
5x=50
x=10
It would take you 10 seconds to catch up to your friend :)
