Volume of a pyramid = Length x width x height / 3
A square base means both the length and width are the same.
Volume = 3 x 3 x 4 /3 = 12 square inches.
Answer:
12in^3
Step-by-step explanation:
v = (1/3) b^2 * H
b^2 = base length^2
(1/3) 3^2 * 4 = 12
1/3 of 9 = 3 x 4 = 12
To celebrate getting a new job, Marco went out for a dinner that cost $100. If the localsales tax is 6% and Marco left a 15% tip on $100, what was the total cost of his meal?
Answer:
$121
Step-by-step explanation:
So if the meal cost $100, finding out the percentages is pretty easy.
The sales tax is 6%, and 6% of 100 is simply 6.
15% of 100 is simply 15.
So, adding the total cost of the meal plus the sales tax plus the tip is simply $121.

Multiply, add the products, round UP and multiply times 6.
NOTE: Why round up? because if you need, for example, 1.22 gallons, you have to get 2 gallons. If you buy just 1 you'll be short, and you can't buy 0.22 of a gallon.
How would you find: the number, 3/7 of which is equal to t ?
Answer:
n = (7/3)t
Step-by-step explanation:
Represente the unknown number by n. Then write the statement symbolically, as:
(3/7)n = t
and then solve the above equation for n by multiplying both sides by (7/3):
n = (7/3)t
Mr. Mastrogiacomo is testing the hypothesis that the proportion of households in a large town that have high-speed internet service is equal to 0.7 against the alternative that the proportion is different from 0.7. What is the chief advantage of using a confidence interval to test this hypothesis rather than a significance test
Step-by-step explanation:
You can use a confidence interval (CI) for hypothesis testing. In the typical case, if the CI for an effect does not span 0 then you can reject the null hypothesis. But a CI can be used for more, whereas reporting whether it has been passed is the limit of the usefulness of a test.
What is the solution to the proportion?

John has 8 different flags that he wants to hang on the wall. How many different ways can the flags be arranged in a row?
Answer:
40,320 different ways
Step-by-step explanation:
Here, we want to arrange 8 flags in a row
In the row, there will be 8 places
The first place has 8 flags to be chosen from
The second place has 7 and like that
So mathematically, the number of ways that we can arrange the flags is 8 factorial ways
We have this as:
8! = 40,320 different ways
Find the surface area of the rectangular prism.

Answer:
SA = 894 cm²
Step-by-step explanation:
SA = (2 x 15 x 9) + (2 x 13 x 9) + (2 x 15 x 13) = 270 + 234 + 390 = 894 cm²
Answer:
894 cm²
Step-by-step explanation:

Find the slope of the line that passes through the following points: `\left(\frac{2}{5},\frac{2}{3}\right)\ \ \left(-\frac{4}{9},\frac{3}{5}\right)` Show the work/explain!
Answer:
3/50
Step-by-step explanation:
Slope m = y2-y1/x2-x1
From the coordinate
x1 = 2/5, y1 = 2/3, x2 = -4/9 and y2 = 3/5
Substitute;
m = (3/5 - 2/3)/-4/9-2/3
m = (9-10/15)/(-4-6/9)
m = -1/15/-10/9
m = -1/15 * -9/10
m = 9/150
m = 3/50
Hence the slope of the line passing through the points is 3/50

A circular pizza has a diameter of 16 inches. Each slice of pizza has a central of angle 45°. What is the area of each slice of pizza?
A. 3.1 in²
B. 6.13 in²
C.25.1 in²
D. 100.5 in²
I know that the area is 8π² I just don't know which answer choice it is.
Answer:
C.
Step-by-step explanation:
Radius = 16 ÷ 2 = 8
[tex]\frac{45}{360} *8^2*\pi =25.1[/tex] (3sf)
You can first find the total area of the circle which is [tex]64\pi[/tex].
Then, you can find the area of the slice of the pizza, if you take the ratio of the angle it creates with the total angle of a circle (360.)
For example, a semicircle's are would be [tex]\frac{180}{360} *8*\pi[/tex].
Answer:
C. 25.1 in²

You had $22 to on four raffle tickets . After buying them you had $6. How much did each raffle ticket cost?
Answer:
X=4
Each raffle ticket cost 4 dollars
Step-by-step explanation:
22-4x=6
solve
-4x=-16
Divide
x=4
Answer: 4 bucks
Step-by-step explanation: 22 bucks at first
You buy four tickets, then you have 6 bucks
If the amount spent is x, then 22 - 4x = 6, so -4x + 22 =6
22 minus 22 is 0, cancel it out — 6 minus 22 is -16
-4 divided by -4 is 0, now you only have x. -16/-4 = 4
X = 4, 4 bucks per raffle ticket
