what are the coordinate of ABC after a dilation with center 0,0 and a scale factor of 3

Answer:

Step-by-step explanation:

c for q 1

A for #2

Answer:

Hey there!

We can arrange this to say, "90% of the whole is 126."

Thus, we can write an equation, where w is used as a variable to represent the whole.

0.90w=126

Divide by 0.90

w=140

The whole is 140.

Answer:

The longer car will travel the fastest down the ramp

The car with the least mass will travel the fastest down the ramp

Changing the ramp height will cause the car to travel faster

Step-by-step explanation:

The longer car will travel the fastest down the ramp

On the table, we are not told what effect a longer car would have on the time taken. We are only told about the mass of car, this means that this would be one of the conclusions you could not draw.

The car with the least mass will travel the fastest down the ramp

We can see on the table that the higher than mass of a car, the quicker the car takes to go down the ramp. This is as the time taken is shorter so it had taken less time. This opposes the statement we are given therefore it should be incorrect.

Changing the ramp height will cause the car to travel faster

On the table, there is not information regarding ramp height meaning that this statement would automatically be incorrect

Hope this helps, have a lovely day! :)

Step-by-step explanation:

Answer:

n=2

Step-by-step explanation:

2n+3+3n=n+11

Step 1: Simplify both sides of the equation.

2n+3+3n=n+11

(2n+3n)+(3)=n+11(Combine Like Terms)

5n+3=n+11

5n+3=n+11

Step 2: Subtract n from both sides.

5n+3−n=n+11−n

4n+3=11

Step 3: Subtract 3 from both sides.

4n+3−3=11−3

4n=8

Step 4: Divide both sides by 4.

after you do that you get the answer witch is

Answer: x ≤ -14

Step-by-step explanation:

3 - \(\frac{1}{2}\)x ≥ 10

1) You want to subtract 3 from both sides of the equation: 3 - \(\frac{1}{2}\)x ≥ 10

                                                                                               -3           -3

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

2) Once you subtract 3 from both sides of the equation you'll be able to cancel out 3-3.

3) After, you'll be left with; -\(\frac{1}{2}\)x ≥ 7

4) You'll then want to divide both sides by -\(\frac{1}{2}\) to isolate x.

5) Divide 7 by -\(\frac{1}{2}\)

6) X ≥ -14, but then you'll want to flip the inequality since you divided by a negative.

7) X ≤ -14

Answer:

320

Step-by-step explanation:

80 ÷ 2 * (3 +5)

80 ÷ 2 * 8

40 * 8

320

Hope this helps!

Answer:

320

Step-by-step explanation:

Using pemdas we would add the 3 and 5 first, so 8. then 80/2 is 40, 8x 40 = 320

Answer:

55%

Step-by-step explanation:

When we are using percentages, what we are really saying is that the percentage is a fraction of 100. "Percent" means per hundred, and so 50% is the same as saying 50/100 or 5/10 in fraction form.

So, since our denominator in 33/60 is 60, we could adjust the fraction to make the denominator 100. To do that, we divide 100 by the denominator:

100 ÷ 60 = 1.6666666666667

Once we have that, we can multiple both the numerator and denominator by this multiple:

33 x 1.6666666666667

60 x 1.6666666666667

=

55

100

Now we can see that our fraction is 55/100, which means that 33/60 as a percentage is 55%.

We can also work this out in a simpler way by first converting the fraction 33/60 to a decimal. To do that, we simply divide the numerator by the denominator:

33/60 = 0.55

Once we have the answer to that division, we can multiply the answer by 100 to make it a percentage:

0.55 x 100 = 55%

Answer:

\(t=\frac{ln 1.5}{0.25}\) OR t = 1.622

Step-by-step explanation:

We know that each large tree costs $4.50, and each small tree costs $2.25. If you buy 4 large trees, that means you will spend 4 * $4.50 = $<<4*4.5=18>>18 on large trees.

If you can spend a total of $50, then you have $50 - $18 = $<<50-18=32>>32 to spend on small trees.

The total cost of the small trees will be s * $2.25, where s is the number of small trees you buy.

To find the maximum number of small trees you can buy, we can set this expression equal to $32 and solve for s:

s * $2.25 = $32

s = $32 / $2.25

s = 14.22

Since you can't buy a fraction of a tree, the maximum number of small trees you can buy is 14.

Answer:

If each large tree costs 4.50 and you need to buy 4, then 4 x 4.50 = $18.00 leaving you with $32.00. With these 32 dollars left, you can now buy 14 small trees, still being left with a remainder of 0.50$.

Answer:

7 feet wide and 84 inches wide

Step-by-step explanation:

2 1/3 yards

2 1/3 · 3 = 7 feet

7 feet · 12 = 84 inches

The length you have to make up a number for yard that is greater than 2 and less than 10

Take whatever number you picked, x, and do the same thing before

x yards

x · 3 =  feet long

feet · 12 = inches long

Answer:

7 feet wide and 84 inches wide

Answer: 27.62

Step-by-step explanation:

plug in 2.3 wherever 'n' is

I'm assuming that the '2' in 8n2 is an exponent

2.3 + 8(2.3)² - 17 =

Using PEMDAS

start out with exponent since there isn't any parenthesis  

(2.3)² = 5.29

2.3 + 8(5.29) - 17

move on to multiplication

8(5.29) = 42.32

2.3 + 42.32 - 17

with addition and subtraction, you do whichever comes first and since this equation starts with addition we'll start there

2.3 + 42.32 = 44.62

then the subtraction

44.62 - 17 = 27.62

The answer is 27.62

Answer:
