Water flows through a pipe at a rate of 5 quarts every 2 days. Express this rate of flow in cups per year.
The rate of flow in cups per year is 3645 cups per year.
How to determine the rate of flow in cups per yearTo convert the rate of flow from quarts per day to cups per year, we first need to convert quarts to cups and days to years.
1 quart is equal to 4 cups,
So 5 quarts is equal to 5 x 4 = 20 cups.
1 year is equal to 365 days, so
2 days is equal to 2/365 = 1/182.5 years.
So the rate of flow in cups per year is 20 cups / (1/182.5 years) = 3645 cups per year.

how do you get the slope
Answer:
See below
Step-by-step explanation:
The way to find the slope is to find how many blocks/number it went up and to the side. The number of blocks it went up on the y-axis, in this case, is 3 and it went along the x-axis once. In order to actually find the slope, you need to put the y over the x. So, 3/1 is equal to three, so the slope of this line is 3
Answer:
y2-y1/x2-x1
Step-by-step explanation:
For instance, say you have points (3,2) and (4,6) on a line.
x1 = 3, y1 = 2, x2 = 4, y2 = 6
6 - 2/4 - 3
4/1
slope = 1
Kailey wrote 8,912,000 in scientific notation as 89.12 times 10 Superscript 5. Which statement best describes Kailey’s work?
Kailey is correct: 89.12 times 10 Superscript 5 equals 8,912,000.
Kailey is not correct: the exponent of ten should be negative.
Kailey is correct: it is written as a decimal number multiplied by a power of ten.
Kailey is not correct: 89.12 times 10 Superscript 5 is not written in scientific notation.
Answer:
kailey is not correct 89.12 times 10 superscript 5 is not written in scientific notation
Step-by-step explanation:
8.912 times 10 superscript 5 is written is scientific notation

Answer:
AOB = -8x + 68
Step-by-step explanation:
AOC = 40°
BOC = 8x - 28
Angle Addition Theorem:
AOB + BOC = AOC
AOB + (8x - 28) = 40
AOB + (8x - 28) + 28 = 40 + 28
AOB + 8x - 8x = 68 - 8x
AOB = -8x + 68
AOB + BOC = AOC
(-8x + 68) + (8x - 28) = 40
-8x + 8x + 68 - 28 =40
0x + 40 = 40
40 = 40
What is the slope of the line shown.
Answer:
The answer is negative one half. If I am wrong let me know because the picture is a little hard to read.
Step-by-step explanation: To find the slope, you look at the Y axis and see where the line crosses perfectly(or goes through) the Y axis first. Then, you look at the x axis and see where the line crosses perfectly on the x axis. For example, the line crosses the Y axis at negative, and the line crosses the X axis at positive 2. The vertical line is the y axis and the horizontal line is the x axis.

Step-by-step explanation:
2/3x-1=5
Add 1 to each side
2/3x-1+1= 5+1
2/3x = 6
Multiply each side by 3/2
2/3x*3/2 = 6*3/2
x = 9
Answer:
x=9
Step-by-step explanation:
You add one to both sides, multiply 3 to both sides (to further isolate x), and then divide by 2 on both sides. When you substitute back in, both sides of the equation are equal to each other.

The question is very vague because it doesn't state the number of rides he wants to go on in minimum.
if you do 1.25x25=31.25
According to that, he will leave with a change of 0.25 and obv u cannot go on half a ride...
