(The right angle is 90 degrees and is marked with a square)
a and b can be switched around
a=5
b=?

A swimming pool is being drained at a rate of 50 gallons per hour. How many milliliters per second is this? Round to the nearest tenth.
Answers
Answer: 3154.16 milliliters / second
Step-by-step explanation:
1 gallon = 3.785 liters
1 liter = 1000 milliliters.
So multiply to convert: 1 gallon x 3.785 liters/gallon x 1000 milliters/liter = 3785 milliters ; 50 gallons = 50*3785 = 189250 milliliters
1 hr = 60 seconds 50 gallons per hour = 189250 mililiters/60 seconds =3154.16 milliliters/second
result : 50 gallons per hour = 3154.16 milliliters / second

Which of the following inequalities matches the graph? (1 point)
graph of an inequality with a solid vertical line through the point 5, 0 and shading to the left of the line
x ≤ 5
x ≥ 5
y ≤ 5
y ≥ 5
Answers
Answer: The inequality that matches the graph is x ≤ 5. This is because the graph has a solid vertical line at x = 5 and the shading is to the left of the line. This indicates that all values of x that are less than or equal to 5 satisfy the inequality.
The inequality x ≥ 5 would not match the graph because the shading would be to the right of the line. The inequalities y ≤ 5 and y ≥ 5 do not match the graph because they are not in the correct form. Inequalities involving y have a graph with a horizontal line, not a vertical line.
A student earned the scores in the data set in one course. {78, 64, 74, 92, 67} What is the mean of the scores?
Answers
Answer: The mean is 75
Step-by-step explanation:
- You add the scores in the data:
78+64+74+92+67 = 375
- Then divide by the number of scores in the data:
there are 5 scores in the data,
1) 78
2) 64
3) 74
4) 92
5) 67
- So:
375/5 = 75 <--- mean
To calculate mean or average from a data set, add all the data points together and then divide by the number of points you added together.
In this case,
78+64+74+92+67= 375/5= 75

Answer:
16.449 = 16.4
9.84 = 9.8
by estimating = 26.2
Answer:
16.5+9.8=26.3
Step-by-step explanation:
The equation is 16.449+9.84. We need to add these together after we round them to the nearest tenth. Well with decimals it goes ones, tenths, hundreths. So The second number past the decimal on the right side, is the one that we are rounding. If the number is greater than 5 then we move the number to the next tenth value.If its less than f5 we do the complete opposite.
16.449 is going to be rounded to be 16.5.
9.84 is going to be rounded to be 9.8
Now that our numbers are rounded we can add them.
16.5+9.8=26.3
I hope this helps!!!

So we just add 8 1/6 + 8 1/6 + 6 2/3 + 6 2/3
but before we can add them up we need to make our fractions have the same denominators
so we multiply the 2/3 by 2 to give us 4/6 then we can add the fractions together
1/6 + 1/6 + 4/6 + 4/6 = 10/6 or 1 4/6
then add 8 + 8 + 6 + 6 + 1 4/6 = 29 4/6 feet

Answer: y = 10x - 10
This means 10 goes into each box, without any minus symbols.
==========================================
Reason:
Recall that slope-intercept form is y = mx+b
m = slopeb = y-interceptWe simply replace m with 10 since this the slope. We replace b with -10 because it's the y-intercept.
So,
y = mx+b
y = 10x+(-10)
y = 10x - 10
---------------
Extra info:
If you wanted to graph this, then I would start at the y intercept location of (0,-10). Then move up 10 units and to the right 1 unit to arrive at (1,0). Draw a straight line through these two points.
To find the x intercept, replace y with 0 and solve for x. The equation 0 = 10x-10 solves to x = 1.
Answer: y=10x-10
Step-by-step explanation:
10 being the point the slope crosses the y-axis
-10 being the degree of the slope
Fred bought 4 new baseball cards to add to his collection. The next day his dog ate half of his collection. There are now only 33 cards left. How many cards did Fred start with ?
Answers
We have to work backwards; he has 33 cards left because his dog ate half of his collection. If we multiply 33 and 2 (which will be how much he had BEFORE half was eaten), we get 66. That is after 4 new baseball cards were bought. We need to subtract 4 from 66 in order to see what he originally had, making that 62 cards!
Charles is in charge of cooking broccoli and zucchini for a large group. He has to spend all $20.10 he has and can carry 11 pounds of veggies. Zucchini costs $1.60 per pound and broccoli costs $2.10 per pound. How many pounds each of zucchini and broccoli can Charles get so that he spends all $20.10 and gets 11 pounds of veggies? Let x represent the number of pounds of zucchini and y represent the number of pounds of broccoli. Show ALL work!
Answers
Answer:
Total equation: X + Y = 11 pounds
Cost equation: 1.60X + 2.10Y = 20.10
Number of Pounds of Zucchini = 6
Number of Pounds of Broccoli = 5
Step-by-step explanation:
You get the equations by just pulling the information from the text.
We then take the total equation and rearrange it to solve for one of our values. I will be using X
X + Y = 11 so first subtract X from both sides to get
Y = 11 - X so now we know what Y equals
next take the cost equation and input X in wherever it shows up so
1.60 (X) + 2.10 (11 - X) = 20.10
now distribute 2.10 to the values in the parathesis to get
1.60X + 23.1 - 2.10X = 20.10
now combine like terms
-0.5X + 23.1 = 20.10
now subtract 23.1 from both sides
-0.5X = -3
now divide both sides by -0.5
X = 6
so now we know that he both 6 pounds of zucchini now plug that into the total equation
6 + Y = 11
subtract 6 from both sides
Y = 5

the starting = a
the base = b
the exponents = x
25.
F: initial value of 100 decreasing at a rate of 5%
a = 100, rate, r = 5%, b = 1 - 0.05 = 0.95
f(x) = 100(0.95)ˣ
G: initial value of 20 increasing at a rate of 5%
a = 20, rate, r = 5%, b = 1 + 0.05 = 1.05
g(x) = 20(1.05)ˣ
solving for f(x) = g(x)
20(1.05)ˣ = 100(0.92)ˣ
divide through by 20
(1.05)ˣ = 5(0.92)ˣ
x㏒(1.05) = ㏒(5 + (0.92)ˣ)
x㏒(1.05) = ㏒5 - x㏒0.92
x㏒(1.05) + x㏒0.92 = ㏒5
-0.015x = ㏒5
x = -46.53
26.
f: initial value of 40 increasing at a rate of 25%
a = 40, r = 25%, b = 1 + 0.25 = 1.25
f(x) = 40(1.25)ˣ
g: initial value of 10,000 decreasing at a rate of 16%
a = 10,000, r = 16%, b = 1 - 0.16 = 0.84
g(x) = 10,000(0.84)ˣ
solving for f(x) = g(x)
40(1.25)ˣ = 10,000(0.84)ˣ
divide through by 40
(1.25)ˣ = 250(0.84)ˣ
x㏒(1.25) = ㏒(250 + (0.84)ˣ)
x㏒(1.25) = ㏒250 - x㏒0.84
x㏒(1.25) + x㏒0.84 = ㏒250
