Answer:
44
Step-by-step explanation:
[tex]BC^{2} = (15-12)^{2} + (8-4)^{2}\\BC^{2} =9 + 16\\BC = \sqrt{9+16} \\BC = \sqrt{25} \\BC = 5[/tex]
P = 12 + 15 + 8 + 4 + 5 = 44

If you were to revolve the figure shown in C you would get the figure above
a) − 5 ( 6 n + 6 ) ≤ 30
b) 8 v − 4 ( v − 8 ) > 8
Answer:
a) n ≥ -2
b) v > -6
Step-by-step explanation:
You did not state what you would like us to do with these. I will assume simplify.
a)
− 5 ( 6 n + 6 ) ≤ 30 first, distribute -5
-30 n + -30 ≤ 30 now, add 30 to both sides so we may isolate n our variable
-30 n ≤ 60 now, divide -30 on both sides so we may isolate n completely. When we do this, the sign changes direction
n ≥ -2
b)
8 v − 4 ( v − 8 ) > 8 first, distribute -4 (note: two negatives equal a positive)
8 v - 4v + 32 > 8 now, simplify
4v + 32 > 8 now, subtract 32 from both sides
4v > -24 now, divide both sides by 4 to isolate v
4v > -24
v > -6

Tesfa is x years old. his father is 4 times as old as Tesfa. Her mother is 7 years younger than his father. If their three ages add up to 101 years, how old is Tesfa?
tesfa = x
dad = 4x
mom= 4x-1
x+4x+4x-1=101
9x+1=101
9x=100
100/9= 11.1

Answer:
15x² - 3x - 7
Step-by-step explanation:
(12x² + 2x) - (-3x²+ 5x + 7)
First open the parentheses by applying the distributive property.
To do this, multiply each term you have inside (-3x⅔ + 5x + 7) by -1.
Thus, you would have the following:
12x² + 2x + 3x² - 5x - 7
Add like terms
12x² + 3x² + 2x - 5x - 7
15x² - 3x - 7

Which system of equations has no solution?
O 5x+5y = 10 and 2x+2y=4
O 3x-6y = 4 and - 4x+8y=7
O 6x+2y = 6 and 7x+3y=9
O 3x-4y = 16 and 2x+3y = 5
Answer:
the first one or the last one
Step-by-step explanation:
5x+5y = 10 and 2x+2y=4
0 = 0
3x-6y = 4 and - 4x+8y=7
0 = 37 / 3
6x+2y = 6 and 7x+3y=9
0 = 3
3x-4y = 16 and 2x+3y = 5
x=4 and y=−1
The set for a school play needs a replica of a historic building painted on a backdrop that is 20 feet long and 16 feet high. The actual building measures 320 feet long by 256 feet high. A stage crewmember writes (x, y) arrow right ( 1/20 x, 1/20y) to represent the dilation. Is the crewmember's calculation correct if the painted replica is to cover the entire backdrop? Complete the explanation.
Answer:
Stage crewmember's calculation is incorrect
Correct = 1/16x 1/16y
Step-by-step explanation:
Given that:
Dimension of backdrop : 20 feets long ; 16 feets high
Actual dimension of building : 320 feets long ; 256 feets high
The correct scale factor can be obtained thus :
Ratio of backdrop dimension to the actual dimension of building
Length : 20 / 320 = 1 /16
Height : 16 / 256 = 1/16
Hence, stage crewmember's calculation of (1/20x ; 1/20y) is incorrect.

Combine Like Terms:
=8y+24+−3y
=(8y+−3y)+(24)
=5y+24
An angle measures 46° more than the measure of its supplementary angle. What is the measure of each angle?
Answer:
67 degree
113 degree
Step-by-step explanation:
Supplementary angles are angles that measure up to 180 degrees. For example, if one angle measures 60 degree, the other angle would measure (180 - 60) 120 degrees
Let x represent the smaller angle
The bigger angle = x + 46
We know that both the smaller and the bigger angle would add up to 180, thus this equation can be written :
x + 46 + x = 180
2x + 46 = 180
Collect like terms
2x = 180 - 46
2x = 134
Divide both sides by 2
x = 67 degrees
the bigger angle = 67 + 46 = 113 degree

Jen uses 8.6 gallons of gasoline to drive 164.7 miles. Which is the best estimate for the number of miles per gallon of gasoline her vehicle gets?
Answer:
19.15 miles/gallon
Step-by-step explanation:
Gasoline used = 8.6 gallons
Distance driven = 164.7 miles
Number of miles per gallon = Distance driven / Gasoline used
= 164.7 miles / 8.6 gallons
= 19.151162790697 miles/gallon
Approximately 19.15 miles/gallon
Number of miles per gallon of gasoline her vehicle gets is 19.15 miles/gallon

Multiple Choice: A prism and a pyramid have identical bases and heights. The volume of the prism is: Twice as large as the pyramid's volume One third as large as the pyramids's volume Three times as large as the pyramid's volume Equal to the pyramid's volume
Answer:
Three times as large as the pyramid's volumeStep-by-step explanation:
Let the volume of prism be Vp
Let the Volume of pyramid be Vy
Vp = Base Area * Height .... 1
Vy = Base * Height/3 ....2
From 2;
Vp = BH/3
BH = 3Vy
Since Vp = BH, then;
Vp = 3Vy
This shows that the volume of prism is three times as large as pyramids volume

Step-by-step explanation:
Answer:
31.5
Step-by-step explanation:
First we want to find what side NP is equal to. To do that we divide 4 by 12
12/4=3 so side mp=3
next we want to find the scale factor of the rectangles. to do that we divide 4 from 9
9/4=2.25
next we want to find what side st is equal too
to do that we multiply 3 by 2.25
3x2.25=6.75
finally we want to find the perimeter and to do that we do 2(6.75)+2(9)
2(6.75)+2(9)=31.5 so the perimeter of rectangle RSTU is 31.5
hope this helps :)
On a map drawn to scale, 5 cm represents 30 kilometers. If a line a the same map that connects 2 cities is 7 cm long, what is the distance between the 2 cities?
Answer:
42
Step-by-step explanation:
You can use proportions to solve this problem.
[tex]\frac{5cm}{30km}[/tex]=[tex]\frac{7cm}{xkm}[/tex]
Now just cross multiply.
5cm*Xkm=7cm*30km
you can simplify the cm and km since its multipying.
5x=210
x=42
