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 :)

Q1: How do you divide a segment into given ratios?
Answer: To find the point P that divides a segment AB into a particular ratio, determine the ratio k by writing the numerator over the sum of the numerator and the denominator of the given ratio. Next, find the rise and the run (slope) of the line. Finally, add (k. the run) to the x-coordinate of A and add (k.

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

Solve for x:
x/7 - 6 = 3
A. 27
B. -63
C. -27
D. 63
Answer:
D. 63
Step-by-step explanation:
First, add 6 to both sides:
[tex]\frac{x}{7}[/tex] - 6 = 3
[tex]\frac{x}{7}[/tex] = 9
Multiply each side by 7
x = 63
So, the correct answer is D. 63
Simplify 6⋅ (x+3)
Apply the distributive property.
6x+6⋅3=x⋅76x+6⋅3=x⋅7
Multiply 66 by 33.
6x+18=x⋅76x+18=x⋅7
Move 77 to the left of xx.
6x+18=7x
Move all terms containing x to the left side of the equation.
subtract 7x7x from both sides of the equation.
6x+18−7x=06x+18-7x=0
Subtract 7x7x from 6x6x.
−x+18=0-x+18=0
Subtract 1818 from both sides of the equation.
−x=−18-x=-18
Multiply each term in −x=−18-x=-18 by −1
Multiply −1-1 by −1-1.
1x=(−18)⋅−11x=(-18)⋅-1
Multiply xx by 11.
x=(−18)⋅−1x=(-18)⋅-1
Multiply−18-18 by −1-1.
x=18

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
On a bicycle ride, Betty rode 7 miles in 2 hours.
At the same rate of speed, how far could she ride in 8 hours?
Answer:
28
Step-by-step explanation:
I'm not sure if this is right
She rode 7 miles in 2 hours, so because she is going at the same speed you times/multiply 7 x 4 in order to determine the miles. I timed it by 4 because 2 hours times 4 = 8 hours.
Hope that helped because I believe it is right :)

Answer:
B
Step-by-step explanation:
When solving multiple choice problems, a reasonable strategy is to look for ways to identify one answer as good, or other answers as bad.
Here, all of the constant vectors in the equations are different, so we can decide the answer based on that.
The only equation with the correct constant vector is choice B.
_____
The constants in the equations are -4, 1, 9 — the values to the right of the equal sign.

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

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
