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.

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 :)

tesfa = x

dad = 4x

mom= 4x-1

x+4x+4x-1=101

9x+1=101

100/9= 11.1

Answer:

I would say that C is the correct answer

Answer:

Step-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

so50×3=150℅

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

Answer:

13+8 = 7+ x

21=7+x

21-7 = x

x = 14

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

yes

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 :)

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.

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

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

Triangular Prism

Step-by-step explanation:

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
