Answer:

Call Brian's age: x, then Sushil's age is: x + 6 and Caroline's age is: x-5

So we have: x + (x + 6) + (x-5) = 64

=> 3x +1 = 64 => x = 63/3 = 21

the youngest of them: 21-5 = 16

Answer:

  E = (-2, -1.5), see attached for a plot

Step-by-step explanation:

We want point E such that ...

  EC/DC = 3/4 . . . . . . . . the ratio of segment lengths is 3/4

  (E -C)/(D -C) = 3/4 . . . . the ratio of coordinate differences is 3/4

  4(E -C) = 3(D -C) . . . . . cross multiply

  4E = 3D -3C +4C . . . . isolate E term

  E = (3D +C)/4 . . . . . . . divide by 4 to find E

__

  E = (3(-3, -4) +(1, 6))/4 = (-9+1, -12 +6)/4

  E = (-2, -1.5)

The point is plotted in the attached graph.

Answer:

y = - 2x + 8

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (2, 4) and (x₂, y₂ ) = (5, - 2)

m = [tex]\frac{-2-4}{5-2}[/tex] = [tex]\frac{-6}{3}[/tex] = - 2, then

y = - 2x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (2,  4)

4 = - 4 + c ⇒ c = 4 + 4 = 8

y = - 2x + 8 ← equation of line

Answer:

A

Step-by-step explanation:

Percentage increment means the part of original value is added to the value. The new length of the living room is 14.4 feet long and new width of the living room is 1.6 feet long. The option A is the correct option.

Percentage of a number or ratio is fraction of hundred. It is expressed with the sign "%".

Given information-

The length of the living room is 12 feet.

The width of the living room is 8 feet.

The owner increases the 20 percent of length and 20% width.

Suppose new length is [tex]l[/tex] feet long. As the owner increases the 20 percent of length. Thus the new length will be sum of original length and the 20 percent of it. Hence,

[tex]l=12+\dfrac{20}{100}\times12 \\l=12+2.4\\l=14.4[/tex]

Thus the new length of the living room is 14.4 feet long.

Suppose new width is [tex]w[/tex] feet long. As the owner increases the 20 percent of width. Thus the new width will be sum of original width and the 20 percent of it. Hence,

[tex]w=8+\dfrac{20}{100}\times8 \\w=8+1.6\\w=9.6[/tex]

Thus the new width of the living room is 1.6 feet long.

Hence the new length of the living room is 14.4 feet long and new width of the living room is 1.6 feet long. The option A is the correct option.

Answer:

40.5 points

Step-by-step explanation:

To start off, I would set up a proportion. You're trying to find how many points out of the total 45 would give you a 90%.

90% as a fraction would be [tex]\frac{90}{100}[/tex].

When you set the two equal to one another, you get this:

[tex]\frac{x}{45} = \frac{90}{100}[/tex]

The bottom numbers are the total amount of points, and the top is how many points a student got.

To solve for x, which is the number of points a student would need to earn, you can cross multiply.

After you do that, you should get:

100x = 4050

To isolate x, you can divide by 100 on both sides.

x = [tex]\frac{4050}{100}[/tex] = 40.5 points

To check your answer, all you have to do is divide.

40.5 ÷ 45 = 0.9

0.9 as a percent is 90%.

Answer:

$5,000

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 5%/100 = 0.05 per year.

Solving our equation:

A = 2500(1 + (0.05 × 20)) = 5000

A = $5,000.00

Answer:

-1

Step-by-step explanation:

2(.5n-3)=n-0.25(12-12n)

first you distribute whatever is on the outside of the parenthesis to the inside of the parenthesis

1n-6=n-3+3n

then you combine like terms and end up with

1n-6=-3+4n

add 6 to each side to get

n=3+4n

subtract 4n from each side to get

-3n=3

divide -3 from each side to get

n=-1

what most likely happen is water droplets will form on the outside of the glass, this is condensation.

Step-by-step explanation:

condensation means: Condensation is the process of water vapor turning back into liquid water, with the best example being those big, fluffy clouds floating over your head. And when the water droplets in clouds combine, they become heavy enough to form raindrops to rain down onto your head.
