Answer:
96
Step-by-step explanation:
The volume of the square pyramid is 96 cm³.
How to find the volume of a square pyramid?
You can locate the extent of a normal square pyramid with the use of the volume formula= base location² × height / 3. Take be aware that the bottom vicinity equals the square of the pyramid's base side period. However, the peak is the perpendicular distance between the pyramid's base and the pyramid's vertex.
By using the given formula, we get
V= a² h/3
=6² * 8 / 3 = 96
The answer is 96 cm³.
The volume of a pyramid is found using the formula V = (1/3) B*h, where 'B' is the base area and 'h' is the height of the pyramid.

Answer:
3rd box = 6
6th box = -22
y=x-12
output = input-12
Step-by-step explanation:
The input value correspond to output value = -6 is +6
The output value correspond to input value = -10 is -22
What is function Rule?A function rule is the relationship between the dependent and independent variables in the form of an equation.
As per the given data if we follow the pattern we get a relation between Output and Input as:
Output= Input-12
or, input= Output + 12
So, we have to find the input when output= -6
Input = -6+12
=+6
Now, to find the output when input is -10
output= -10-12
=-22

Marco got 15 questions wrong on his 30-question test. What is his grade as a percent?
Answer:
15
Step-by-step explanation:
The grade percentage of Marco is 50%.
What is percentage?A percent is a dimensionless number, meaning that it has no units of measurement, since it represents a part of whatever whole is being measured.
Given that, Marco got 15 questions wrong on his 30-question test.
We need to find his grade as a percent,
So,
Since he got 15 answers wrong,
Therefore, his correct answers = 30-15.
That mean his grade in marks = 15
Now, his grade in percent = 15/30 x 100 = 50%
Hence the grade percentage of Marco is 50%.

Answer :
$38 + $2(n) where n is the no. of cars.
Step-by-step explanation:
He earns $38 daily which is fixed and additional $2 wage depends on the no. of cars which means no. of cars will determine how many $2's he earns.
25 cars = $38 + $2 (25) = $88
30 cars = $38 + $2 (30) = $98
35 cars = $38 + $2 (35) = $108
40 cars = $38 + $2 (40) = $118

Evaluate the expression. 1/7^9⋅1/7^−6 The value of the expression is .
Answer:1/343
Step-by-step explanation:
you can use the exponent rule so you would be left with (1/7)^9-6 which would simplify to (1/7)^3. The if you not using a calulater, you can take 1/7 and individually cube the numbers to find the final answer. So 1^3/7^3. This would simplify to 1/7^3. 7^3 is 343. This leaves you with the final answer.
Find the next term in the sequence:

A. 243/469
B. 100/469
C. 27/156
D. 84/469
Answer:
A. 243/469
Step-by-step explanation:
Looking at the terms here, it seems that the this powers of 3 divided by 469.
3 is 3¹. 9 is 3². 27 is 3³. 81 is 3⁴.
Knowing that, then 3⁵/469 is the next term. 3⁵ is 243, so the next term is 243/469, which is A.

An aluminum can has a capacity of 2.37 L. What is the capacity of the can in milliliters?
(1 L = 1,000 mL)
Answer:
2,370 mL
Step-by-step explanation:
1000mL = 1 L, so I multiplied 1000 by 2.37
If they ask for it to be set up as a proportion, I would write 1/1000 = 2.37/x and cross multiply. x = 2,370

Three neighbors plan to complete fencing projects this spring. As shown in the diagrams below, Neighbor A plans to fence in his rectangular backyard with a 6-foot tall wooden privacy fence. Neighbor B plans to construct a circular chain link fence around his pool. And, Neighbor C is putting a vinyl fence around three side of his front yard. Note: Diagrams are not drawn to scale. Intended fences are marked with a dashed line.
Answer:
- The neighbor that has the most amount of fence to put up is: Neighbor A.
- The neighbor that has the least amount of fence to put up is: Neighbor C.
Step-by-step explanation:
To calculate the amount of fence that Neighbor A has to put up, you need to add the following distances:
Convert yards to feet (Remember that :
To calculate the amount of fence that Neighbor B has to put up, you need to use the formula for calculate the circumference of a circle:
Where r is the radius.
In this case, the radius is:
Substituting, you get:
To calculate the amount of fence that Neighbor C has to put up, you need to add the following distances:
Therefore, the neighbor that has the most amount of fence to put up is: Neighbor A.
The neighbor that has the least amount of fence to put up is: Neighbor C.

Solve using the quadratic formula 1
Answer:
Step-by-step explanation:
Unless we set x^2 + 8x + 15 equal to zero, we don't have an equation to be solved. I will assume that the problem is actually x^2 + 8x + 15 = 0.
The coefficients of this quadratic are {1, 8, 15}, and so the "discriminant" b^2 - 4ac is (8)^2 - 4(1)(15), or 4. Because the discriminant is positive, we know that there are two real, unequal roots.
Continuing with the quadratic formula and knowing that the discriminant is 4, we get:
-8 ± √4 -8 ± 2
x = ---------------- = --------------- , or x = -2 ± 1: x = -3 and x = -5

Step 1: Our output value is 700.
Step 2: We represent the unknown value with $x$x.
Step 3: From step 1 above,$700=100\%$700=100%.
Step 4: Similarly, $x=42\%$x=42%.
Step 5: This results in a pair of simple equations:
$700=100\%(1)$700=100%(1).
$x=42\%(2)$x=42%(2).
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have
$\frac{700}{x}=\frac{100\%}{42\%}$
700
x=
100%
42%
Step 7: Again, the reciprocal of both sides gives
$\frac{x}{700}=\frac{42}{100}$
x
700=
42
100
Therefore, 42% of 700 is 294.
