Mr. F's bathtub drains at a rate of 2 gallons per minute but fills at 3.5 gallons per minute. After a 4000-calorie dinner, Mr. F forgot to close the drain before filling his 60 gallon tub. How long did it take for the tub to fill? Express your answer in minutes.

Answers

Answer 1
Answer:
40 minutes
Step-by-step explanation:
It will take 40 minutes because if the water drains at a rate of 2 gallons a minute but fills at 3.5 gallons a minute, that will mean that the water will still fill at 1.5 gallons per minute.

If you multiply 1.5 gallons by 20 minutes the tub will be half full with 30 gallons of water so that means if you multiply 20 minutes by 2 it will mean that the tub will have 60 gallons of water and it would have taken 40 minutes to fill.

Part A:

8 x 7 = 56; 56 x 10 = 560

Part B:

504

Part A & B explanation:

If you notice, there are no decimals in the answers so it's clear they round them. 8.4 rounded is 8 & 6.9 rounded is 7. To find the area of a singular rectangle is length x width. 8 x 7 = 56. In part A the directions say "best estimate" signaling that it isn't the exact answer you're looking for. 8 x 7 = 56; 56 x 9 = 504 would be the exact answer. (Answer for part b).Therefore, the answer for part A is 8 x 7 = 56; 56 x 10 = 560. Because 560 is the closest to 504 on the board.

Write an exponential growth function to model each situation,
15. Initial value: 20
Growth factor: 1.25

Answers

Answer: f(x)=20(1.0125)^t

Step-by-step explanation:

use the formula P(1+r)^t when considering exponential growth (make it 1-r if decay)

P - principal (initial) value

r - growth rate (as a decimal! so divide by 100)

t - time (can be years, months, days, etc)

so now that we know the formula, just plug in everything you know!

P=20, r=0.0125, t=x

so the function is

20(1+0.0125)^t or 20(1.0125)^t

since we dont have a defined time, that becomes the variable for x, the one we can manipulate, so if they ask for 10 years, just replace t with 10!

What are the coordinates of point D(4/7, 3 1/3) after it reflected across the x-axis

Answers

Answer:it’s 4 units to the left

Step-by-step explanation: The point (4,3) reflected the x-axis,

=> The x remains the same, the y flips over the x-axis to be negative

     (4,3) ==>> (4,-3)

The point (-3,-8) is reflected in the y-axis.

=> The y remains the same, the x flips over the y axis to be negative

     (-3,-8)==>>(3,-8)

The point (2,4) is reflected in the line x = -3.

=> The x remains the same, the y flips over the x= -3 line.

     Instead of reflecting over the x-axis (or the x = 0) line

     and just being +4 or 4 above the x-axis to -4 or 4 below the x-axis-axis-axis

     you have +4 being 7 above the x= -3 line so you need

     7 below the x= -3 line or -10  SO

      (2,4)==>>(2,-10)

The point (a, b) is reflected in the line y = x

     Consider that the line x=y is a 45-degree diagonal.

     Imagine a point on the 45-degree at +3  i.e. (3,0)

     Imagine a line perpendicular to x=y from the point (3,0)

           (sorry there is no way to draw on here - try drawing it)

    The line would hit the x-axis-axis at (0,3)

    So you can see the x becomes y and y become x.

     (a,b)==>>(b,a)

For

ΔXYZ is defined by its vertices X(1,3), Y(-3,5), and Z(0, -5).

       ΔXYZ is reflected in the y-axis.

So for each of the 3 points X, Y, and Z reflect about

       the y-axis the same way in the second example above

       and you will have the 3 new points X’,  Y', and Z’

The translation T: (x, y) → (x -2, y + 4) maps the point (2, -3) to

The translation T: (x, y) → (x + 3, y - 2) maps the point (-4, -3) to

     What you need to do here is just plug the values for X and Y into the translation.

     e.g. for T: (x, y) → (x -2, y + 4)  plug (2,-3) of x=2 y=-3 into (x -2, y + 4) and get the new values.

4x - 2(x - 2) = -9 + 5x - 8

Answers

Answer is x = 7

Step by step

4x -2(x - 2) = -9 +5x -8
Distribute

4x -2x +4 = -9 +5x -8
Combine

2x + 4 = 5x -17

Subtract 5x from both sides to isolate variable

2x -5x +4 = 5x -5x -17
Combine

-3x +4 = -17

Subtract 4 from both sides to combine constants

-3x +4 -4 = -17 -4
Combine

-3x = -21

Divide both sides by -3 to solve

-3/-3 x = -21/-3

x = 7

What is a numerical expression?

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Given, John’s age is 12 more than 2 times Sam’s age. The sum of their ages is 65.

Let, The age of Sam be 'x'.

Therefore, 2x + 12 + x = 65.

3x = 53.

x = 17.66.

So, Sam is 17.66 years old and john is (65 - 17.66) = 47.34 years old.
