When D’Ante looked at the car lot, he noticed that for every 2 red vehicles, there were 6 grey vehicles. If there are 144 total vehicles in the parking lot, how many of them are red? How many are grey?

Answers

Answers:

36 red cars108 grey cars

========================================================

Work Shown:

The ratio 2 red : 6 grey reduces to 1 red : 3 grey when we divide both parts by 2. For every 1 red car, there are 3 grey cars. There are triple as many grey compared to red.

Let x be the number of red cars. Since there are 3 times as many grey cars, this means 3x represents the number of grey cars.

The total number of cars can be represented by the expression x+3x = 4x

Set this equal to the total number of cars (144) and solve for x

4x = 144

x = 144/4

x = 36

There are 36 red cars.

Subtract that value from 144 to find 144-36 = 108 grey cars.

----------------------------------------

An alternative way to solve:

(2 red)/(6 grey) = (x red)/( (144-x) grey)

2/6 = x/(144-x)

2(144-x) = 6x .... cross multiply

2*144 - 2*x = 6x

288 - 2x = 6x

288 = 6x+2x

288 = 8x

8x = 288

x = 288/8

x = 36

If there are 144 vehicles in the parking lot, then 36 cars are red.

Also, 144 - x = 144 - 36 = 108 cars are grey.

36 red cars
108 grey cars

James types 90 words in 2 minutes. At this rate, how many words can James type in 15 minutes?

Answers

it would probably be 675 cause i did it and got that

Answer:

675 words

Step-by-step explanation:

If James can types 90 words in 2 minutes, we can assume that he can type 45 words per minute. If we multiply 45 words per minute by 15 minutes, we get 675.

If Wendell creates a scale drawing using the scale 1 inch to 10 feet, what will the dimensions of the deck in the scale drawing be?

Answers

Answer:

You did not send a picture, so here is how you generally do it.

12 inches is 1 foot, and if you want to scale to be 1 inch to 10 feet it should be 10 times that, so 12 * 10 = 120. The scale is 120. Multiply the dimensions of the deck by 120 for your answer.

What is Straight Line?

A line is an infinitely long object with no width, depth, or curvature.

If the points lie on the graph, they should satisfy it when substituted in place of x coordinate and y coordinate.

So, on substituting point P we get

3a=6

Divide both sides by 3

a=2

And on substituting point Q we get

-3a+4b=6

-3(2)+4b=6

-6+4b=6

Add 6 on both sides

4b=12

Divide both sides by 4

b=3

Hence, the value of a is 3 and value of b is 3.

Monica is making a design for art class she is experimenting with how to transform line segment AB in her design

Answers

Answer:

it will be A.  Line segment AB and its image will be the same length and in different  positions.

Step-by-step explanation:

hope this helps

Answer:

A reflection does not change lengths, so answers B and D are not right.

In most cases, a reflection will change the position of any object; so answer A would be right.

However, if segment AB is contained inline l, its reflection in line l will be in the same position.

Or if line l is the perpendicular bisector of segment AB, then the reflection of segment AB inline l will be in the same position as segment AB, but with the two endpoints, A and B switched.

So, with the question as posed and no further information about the relationship of line l and segment AB, the best answer is A; but in certain cases answer, C could be right.

−6x+8/6−3/2x−1/2+5/2x

Do not use decimals in your answer

Answers

Answer: =−5x+5/6

Step-by-step explanation:

Your equation:

−6x+8/6-3/2x-1/2+5/2x

Gather all the numbers with the x variable:

-6x - (3/2x) = -7 1/2x

-7 1/2x + (5/2x) = -5x

-5x is the answer to your first part.

Finally, gather all the numbers without the x variable.

(8/6) - (1/2) = 5/6

This makes your answer into -5x+5/6 ! Hope this helps :D

just sub the x in the equations with each of the given x numbers
Ok it’s pretty easy!

Under the X, that’s what we call a input! And I’ll take the equation from number 11
(X-5)

Under the X we see numbers like (-4, 8, 1, 3, 4)

What we do here is we grab our equation (x-5) and we exchanged “X” for one of the numbers, I’ll use the first example! Which is (-4)

So our equation will look like this
(-4 - 5) and what you do know is solve it which will give you the answer of “-9”

So now what you do is put negative nine as the y for that column and bam!

In resume you plug in the numbers under x for the x in the equation then the results will be your output or in other words you “y”

Dakota earned $15.75 in interest in Account A and $28.00 in Account B after 21 months. If the simple interest rate is 3.0 for Account A 4.0% for Account B, which account had the greater principal? Explain

Answers

Answer: account B had the greater capital.
Step-by-step explanation:
The formula for determining simple interest is expressed as
I = PRT/100
Where
I represents interest paid on the amount deposited.
P represents the principal or amount deposited
R represents interest rate
T represents the duration in years.
Considering account A,
I = $15.75
T = 21 months = 21/12 = 1.75 years
R = 3%
Therefore,
15.75 = (P × 3 × 1.75)/100
15.75 = 0.0525P
P = 15.75/0.0525
P = 300
Considering account B,
I = $28
T = 21 months = 21/12 = 1.75 years
R = 4%
Therefore,
28 = (P × 4 × 1.75)/100
28 = 0.07P
P = 28/0.07
P = $400
Therefore, account B had the greater capital.
account b had greater
