Step-by-step explanation:

I just did it

The scale factor is determined by the ratio of the lengths of corresponding sides of two similar figures. To find QY, divide QY' by the scale factor.

The scale factor is the ratio of the lengths of corresponding sides of two similar figures. In this case, line WY and line W'Y' are similar figures, and the scale factor is determined by the ratio of their lengths. The scale factor can be calculated by dividing the length of W'Y' by the length of WY. Given that QY' = 4.125, the scale factor can be determined by dividing QY' by QY. So, the scale factor is 4.125/QY. To solve for QY, divide QY' by the scale factor: QY = QY'/scale factor. Therefore, QY = 4.125/(4.125/QY) = (4.125*QY)/4.125 = QY.

Eight less than a number = n - 8

One-third the number = 1/3 * n or n/3

So eight less than a number is one-third the number"

n - 8 = n/3

Answer is c) n-8 = n/3

Given equations : Equation A:  4y -3x =16 and

Equation B: -x-8y =3.

We are given a point (-5,0.25) plugging it in first equation

4(0.25) -3(-5) =16

1+15 =16.

16 =16 : Satisfies first equation.

We are given a point (-5,0.25) plugging it in second equation.

-(-5)-8(0.25) =3.

5 - 2 = 3.

3=3.

So, when x = -10.

If you notice, -10 is NOT in the domain (the domain is (-3,13))

so, there is no solution.

Answer: -24

Step-by-step explanation:

Step one :

For the first equation

Given that x=-10

F(x) =2x-4 if 3<x<10

x exists in this domain

Substituting x in the equation we have

F(-10)=2(-10)-4

F(-10)= -20-4

F(-10)=-24

Step two :

For the second equation

Given that x=-10

F(x) =x²-+3 if 10<=x<13

x does not exist in this domain

the slope is 9 and the y-intercept is - 2

the equation of a line in ' slope-intercept form ' is

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

y = 9x - 2 is in this form

with slope m = 9 and y-intercept c = - 2

Answer:

x=12.50

y = 17.50

Step-by-step explanation:

x = Amount of one Derek withdrawal

then amount of John withdrawal =x+5

Total withdrawals of Derek = no of times x one time withdrawal

= 7(x) = 7x ... i

No of John withdrawal = no of times x one time withdrawal

= 5(x+5)  ... ii

Given that i and ii are equal

i.e. 7x =5(x+5)

7x = 5x+25

2x =25

x = 12.50 dollars

Y = 17.50 dollars

Checking part:

total derek withdrawal = 7(12.5) =87.50

Joh's withdrawal = 5(17.50) = 87.50

Since both are equal, our answers are right.

Solution:  Derek withdrew each time 12.50 dollars each for 7 times and John withdrew 17.50 dollars each for 5 times.

The answer is b. It is the only choice that equals the right answer. You could also write this as 3 * 10^4, which is equivalent to b.

First count how many zeros 30,000 has it has four. So you need to multiply it by something that has four digits. So B. 3 x 1000. Or expressed in scientific notation.

3 × [tex]10^{4}[/tex]

One company wants $10 per 3.5 hours, so they want 10 / 3.5 ≈ 2,86 dollars per hour (after rounding to the closest hundreths).

Second company wants $1.25 per half an hour, so they want 2 * 1,25 = 2,50 dollars per hour.

The unit rate is 2,86:2,50

One hour = 60 minutes

If it is travelling at 75 kilometers per hour, we can divide 75 by 60 to find out how fast it can travel in one minute.

75/60 = 1.25

The car can travel 1.25 kilometers per minute.

However, the questions is asking how many meters it travels in one minute.

A kilometer is 1000x the size of a meter.

Thus, if we multiply 1.25 by 1000x we'll get the amount of meters.

1.25 * 1000 = 1250

The car travels 1250 meters in one minute.

Final answer:

A car traveling at 75 km/h covers 1,250 meters in one minute by converting the speed to meters per hour and then dividing by the number of minutes in an hour.

Explanation:

To convert the car's speed from kilometers per hour to meters per minute, we can use the following conversion factors: There are 1,000 meters in a kilometer and 60 minutes in an hour. Therefore, if a car is traveling at 75 kilometers per hour, we can calculate the distance it travels in one minute as follows:

So, a car traveling at 75 kilometers per hour travels 1,250 meters in one minute.

Answer:

I did this on a Calc. but it is 6.666667

Step-by-step explanation:

Calculator

To divide 20 by 3, we use long division. The quotient is 6 remainder 2, or 6.67 as a decimal.

To divide 20 by 3, we can use long division. The divisor, 3, goes into the first digit of the dividend, 2, once. We then multiply 3 by 1, which equals 3, and subtract that from 2. The remainder is 2. We bring down the next digit, 0, and the divisor goes into 20 six times. We then multiply 3 by 6, which equals 18, and subtract that from 20. The remainder is 2. Since there is no longer a digit to bring down, we have our final answer: 20 divided by 3 equals 6 remainder 2, or 6.67 as a decimal.

length = y

width = length-3 = y-3

Area = (length)(width) = y(y-3) = y^2-3y

The final answer is y^2-3y

Answer:

0.8

Step-by-step explanation:

3/4+1/5=0.8 or 8/10

Answer:

true

Step-by-step explanation:

larger angle = 50°

complementary angles sum to 90° , hence

2x + x + 30 = 90

3x + 30 = 90 ( subtract 30 from both sides )

3x = 60 ( divide both sides by 3 )

x = 20

thus 2x = 2 × 20 = 40° and x + 30 = 20 + 30 = 50°

the larger angle is x + 30 = 50°

The kinetic energy of the girl is 120 J while the dog has 40 J.

if the dog speeds up, it would have a kinetic energy of 160J.

In order to get these answers, you need to use the formua for kinetic energy which is KE=1/2 mv^2. mass=m, v=velocity and KE= Kinetic Energy.

Answers of tthe questions are reasonable because you would gain more energ if you run faster and also more energy if you gain more mass.

Divide both sides by -2!

Answer: x=11

The correct answer is:

D. No, because [tex]\(-5^2\)[/tex] equals -25 and [tex]\((-5)^2\)[/tex] equals 25.

To evaluate the expression [tex]\( -5^2 \)[/tex] and [tex]\( (-5)^2 \)[/tex], we need to understand the order of operations.

According to the order of operations (PEMDAS/BODMAS), exponentiation takes precedence over negation.

So, [tex]\( -5^2 \)[/tex] means [tex]\( -(5^2) \)[/tex], which equals -25.

On the other hand, [tex]\( (-5)^2 \)[/tex] means [tex]\( (-5) \times (-5) \)[/tex], which equals 25.

Therefore, [tex]\( -5^2 \)[/tex] is not equal to [tex]\( (-5)^2 \)[/tex].

The correct answer is option D.

Answer:

You can watch 13 movies

Step-by-step explanation:

Cost of Carl's Cable Company:

Cost of Teleview Cable Company

Lets take that you watch [tex]x[/tex] paper view movies per month.

Then the cost of paper view movies = $[tex]4*x[/tex]

Now we can calculate the total cost of cable TV if you watch [tex]x[/tex] paper view movies per month.

Total cost = Monthly service + Paper view movie cost

                 =[tex]55+4x[/tex]

Now we can write an inequality for the Cost of Car's Cable Company cost being less than Teleview as follows;

[tex]55+4x≤110[/tex]

Now we can solve this inequality and find [tex]x[/tex] the number of movies you can watch so that the Cost of Carl's cable company will be less than teleview.

[tex]55+4x≤110[/tex]

=[tex]4x≤110-55[/tex]

=[tex]4x≤55[/tex]

=[tex]x≤13.75[/tex]

Therefore, if you watch less than 13.75 movies per month the cost of Carl's cable company cost will be less than Teleview.

So you can watch 13 movies (Number of movies has to be a whole number)

We are asked to find the probability that a person consumes 1500-2000 calories in a day.

Total number of people who were surveyed=500

Total number of people who consume 1500-2000 calories in a day are:250

              Hence, Probability is:

                250/500=1/2=0.50

Answer:  D. 0.50

Step-by-step explanation:

Formula for probability :

[tex]\text{Probability}=\dfrac{\text{Favorable outcomes}}{\text{Total outcomes}}[/tex]

The given two-way table :
