In a flash of sheer brilliance, Stefan invents a time machine! The machine uses a small nuclear reactor to generate the electricity it needs to travel back in time. There is a proportional relationship between how many years Stefan wants to travel back in time, x, and how much electricity (in megawatts) his time machine needs, y . ​

Answer: 1924

Step-by-step explanation:

Number if seats in the theater = 3700

Percentage of seats filled by students in the theater = 52%

The number of 6th graders that went on the trip will be gotten by multiplying 52% by 3700. This will be:

= 52% × 3700

= 52/100 × 3700

= 0.52 × 3700

= 1924

1924 students went on the trip

Answer:

Step-by-step explanation:

The number of pennies will be 2 more than a multiple of 10. 2 pennies and 9 dimes is not enough coins. 12 pennies and 8 dimes is exactly enough.

__

This one is easy to figure by "trial and error," as there is only one trial that makes any sense.

If you want to figure it using an equation, it usually works well to let a variable represent the quantity of the higher-value coin. If d is the number of dimes, then 20-d is the number of pennies. The total number of cents is ...

  10d +(20-d) = 92

  9d = 72 . . . . . . . . . subtract 20

  d = 8

  20-d = 12

There are 8 dimes and 12 pennies.

Answer:

Yes, you were correct with x=5. AB=CD=25 and AC=BD=23

Step-by-step explanation:

You already have x=5.

The first question is AB=CD=__ so you can just look at AB and you see it says 5x. You just substitute in the 5 for the x because you already got that. 5 times 5 = 25 and there is your first answer.

AC=BD=__ is your next question and you just look at AC and see "5x-2" and substitute in the x again. So you'll have 5(5)-2 which is 25-2 and your answer will be 23.

Yes, it is correct with x=5.It comes AB=CD = 25 and AC = BD=23.

Given that,

Based on the above information, the calculation is as follows:

AB = CD

Here AB = 5x

= 5(5)

= 25

So AB = CD = 25

Now

AC = BD

Here

AC = 5x - 2

= 5(5) - 2

= 25 - 2

=23

So AC = BD = 23

Therefore we can conclude that Yes, it is correct with x=5.It comes AB=CD = 25 and AC = BD=23.

Answer:

x = 13

y = 12

Step-by-step explanation:

4x and 52 have to be equal because they are opposites on the same line. So because of this we can make a simple equation to find x.

4x = 52

divide both sides by 4 and you have x

x = 13

to find y on the other equation, since we know two of the angles, we can add up all three angles and make them equal to 180 (the sum of all angles on a triangle)

90 + 52 + (3y +2) = 180

first subtract 90 and 52 from both sides to leave the equation alone

3y + 2 = 38

second substract 2 to isolate the variable

3y = 36

lastly divide both sides by three

y = 12

Answer: -1 ≤ x ≤ 4.

Step-by-step explanation: To solve this problem, we first add 7 to the inequality: -4 ≤ 4x ≤ 16. Then we divide the entire equation by 4 to get -1 ≤ x ≤ 4.

Slope-Intercept Form: y = mx + b

Step 2: Find Standard Form

(2) The sum of angles in a quad is always 360.

Take line RST and you get the value of angle RSP as 180 - 110 which is 70. This is due to them being linear pairs. Angles formed by a straight line is always 180 degrees!

110 + x = 180

x = 70

Now for y

Since we found values for all the 3 angles, which are 140, 110, 70, the 4th one is gonna be the sum of all the 3 angles subtracted from 360

140 + 110 + 70 + y = 360

y = 360 - (140 + 70 + 110)

y = 50 <- That's the answer.

(2) 2 of the angles are already given. If you look, angle U is 90 degrees. That's what the sign represents.

Angle Q (In the quad) is going to be 180 - 110 (Linear pairs) = 70

Since we found 3 angles the 4th one (angle R) is going to be 360 - (90 + 50 + 70) which is 360 - 210 which is 150.

Since angle R in the quad is 150, due to linear pair property, 3x = 180 - 150

3x = 30

x = 30/3 = 10

x = 10 <- That's the answer :D

Answer:

The value of x is 3

Step-by-step explanation:

The stage is rectangular in shape.

The formula for area of a rectangle is:

Length × Width

Length = 24 feet

Width = 4x + 4 feet

Hence:

384 = (4x + 4) × (24)

384 = 96x + 96

Collect like terms

384 - 96 = 96x

288 = 96x

x = 288/96

x = 3

The value of x is 3

The data described on the dot plot will be spread, gap, peak, and cluster. Then the correct options are A, B, C, and F.

A statistical chart called a dot chart or dot plot is made up of data points that are represented on a very basic scale, usually using filled-in circles. The dot chart comes in two widely used but quite different forms.

A statistical chart made up of data points drawn on a relatively basic scale is known as a dot diagram, sometimes known as a dot plot. One of the simplest statistical plots is the dot plot, which is typically applied to tiny data sets. They can be used to draw attention to outliers, gaps skew in the distribution and clusters.

Answer:

She is not correct, the claim is wrong

Step-by-step explanation:

Here, we want to check if a claim

made is correct

We can represent the exponential function as;

y = I( 1 - r)^t

So in this case;

1 - r = 0.72

r = 1 - 0.72

r = 0.28

This is same as 28%

So what this mean is that we expect a decrease of 28% per day

There are 24 hours on a day

So the decrease per hour will be 28%/24 = 1.167%

So as we can see the claim is wrong

The model of the level of water in a draining pool is an illustration of an exponential function.

Inayah's claim is incorrect, because the water drains at 28% per hour

The function is given as:

[tex]\mathbf{y = 12(.72)^t}[/tex]

An exponential function is represented as:

[tex]\mathbf{y = a(1 - r)^t}[/tex]

Where r represents the rate.

So, by comparison

[tex]\mathbf{1 - r = 0.72}[/tex]

Collect like terms

[tex]\mathbf{- r = 0.72 - 1}[/tex]

[tex]\mathbf{- r = -0.28}[/tex]

Multiply both sides by -1

[tex]\mathbf{r = 0.28}[/tex]

Express as percentage

[tex]\mathbf{r = 28\%}[/tex]

This means that, the water drains at 28% per hour

Hence, Inayah's claim is incorrect
