On Monday, water was pumped out of the pool at a constant rate, starting at 12:00 p.m.

At 12:15 p.m., the water in the pool was 45 inches deep.

At 12:35 p.m., the water in the pool was 41 inches deep.


Part A - By how many inches does the depth of the water decrease each minute?

Answers

Answer: Every ten minutes the water decreases by two, so you would divide 2/10, which would be 0.2, meaning the water decreases 0.2 inches per minute.

Answer:

so every 20 minutes it goes down by 4 inches so 20x-4y

Step-by-step explanation:

20x-4y means every 20 minutes it goes down 4 inches

Question: (10-2)+(5x293)+(82x90)-2938

Answers

Answer:

5915

Step-by-step explanation:

Ok, so in 5th grade, we were taught to use PEMDAS (parentheses, exponents, multiplication, division, addition, subtraction), to get a long question correct. It has to be in that order, so start with parentheses. Here is the whole equation simplified: 8+1465+7380-2938. Now you will go from left to right. So, you have 1473+4442. And last, simplify, 1473+4442=5915. Hopefully this helped and if it did please mark it brainliest.

Answer:

5,915

Step-by-step explanation:

PEMDAS

P= Paranthesis:

(10-2)= 8

(5x293)=1,465

(82X90)=7,380

Then: AS add and subtract

8+1,465+7,380-2938=

5,915

Yolanda is filling her bathtub. The table shows the number of gallons of water in the bathtub at different times since she started filling it. Time (minutes) 1, 1.5, 2 Water (gallons) 16.50, 24.75,33. Now find the constant of proportionality (in gallons per minute) for the second and third rows of the table. Show your work.

Answers

Answer:

K= 16.5 gallons per minute

Step-by-step explanation:

Time t (minutes) Water g (gallons)

For t= 1, g= 16.50,

for t= 1.5 ,g= 24.75

For t= 2,g= 33

Let the function be

Gallons g= k(time t)

Where k is the constant of proportionality

16.5= k(1)for when t= 1

24.75= k(1.5) ..for when t= 1.5

Solving gives

8.25=k(0.5)

8.25/0.5= k.

16.5 = k

K= 16.5 gallons per minute

Distances in space are measured in light-years. The distance from Earth to a star is 6.8 × 1013 kilometers. What is the distance, in light-years, from Earth to the star (1 light-year = 9.46 × 1012 kilometers)?

2.66 light-years
7.18 light-years
7.74 light-years
9.46 light-years

Answers

Answer:

7.18 light-years

6.8 x 10^13 = 68,000,000,000,000

9.46 x10 ^12 = 9,460,000,000,000

6.8 x 10^13  *  1 light year / 9.46 x 10^12 = 7.188 light years.

Answer:

x = -16[tex]\frac{2}{3}[/tex]

Step-by-step explanation:

When there are two lines that intersect at one point, the two angles that are directly opposite each other are equal. So in this case, (6x+175) = (3x + 127)

6x + 175 = 3x + 125

6x - 3x = 125 - 175

3x = -50

x = -50 ÷ 3

x = -16[tex]\frac{2}{3}[/tex]

3x + 127 = 6x + 175 (Since its an opposite angle)

3x = 48

x = 16

The work of a student to solve the equation 4(2x − 4) = 8 + 2x + 8 is shown below:


Step 1: 4(2x − 4) = 8 + 2x + 8

Step 2: 6x − 8 = 16 + 2x

Step 3: 6x − 2x = 16 + 8

Step 4: 4x = 24

Step 5: x = 6



In which step did the student first make an error and what is the correct step?


Step 2; 8x − 4 = 2(6 + x + 6)

Step 2; 8x − 16 = 16 + 2x

Step 3; 6x − 2x = 16 − 8

Step 3; 6x + 2x = 16 + 8

Answers

Step 2; 8x-16 = 16+2x
