I need help on finding the height of a triangular pyramid
if there’s no work, I don’t get credit
I will give Brainliest
Answers
Answer:
20 in
Step-by-step explanation:
The formula for the volume of a triangular pyramid is V=1/3 x B x H, in which B is the area of the base and H is the height. You're given the volume and area of the base so you can just plug that into the formula. You will get 120 = 1/3 x 18 x H. You can multiply the 1/3 and 18 so you will get 120 = 6H. In this case, you are solving for H so you need to isolate the variable. You can do this by dividing both sides by 6. You will end up eith 20 = H.

d) 28 in²
Step-by-step explanation:
A = bh
A = 7h
Find 'h' by using the Pythagorean Theorem:
3² + h² = 5²
9 + h² = 25
h² = 16
h = √16 = 4
A = 7×4 = 28
Answer:28
Step-by-step explanation:
Area of a parallelogram= bh
base-7
height- 4
using the Pythagorean theorem, [tex]5^{2}[/tex] - [tex]3^{2}[/tex]= [tex]\sqrt{16}[/tex] = 4
7 * 4 = 28

f(6) = 28

Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightAlgebra I
FunctionsFunction NotationStep-by-step explanation:
Step 1: Define
f(x) = 5x - 2
f(6) is x = 6
Step 2: Evaluate
Substitute in x [Function]: f(6) = 5(6) - 2Multiplication: f(6) = 30 - 2Subtraction: f(6) = 28=========================================================
Explanation:
Everywhere you see an x, replace it with 6
f(x) = 5x - 2
f(6) = 5*6 - 2
f(6) = 30 - 2
f(6) = 28
Remember that 5x is the same as 5*x or "5 times x". So that's why 5x turned into 5*6 after replacing x with 6. After every x is replaced, you follow the order of operations PEMDAS to simplify.

Find the median of the data set: 3, 7, 3, 2, 7, 9.
A: 7
B: 5
C: 5.3
D: 3
Answers
To find the median, you order the numbers from least to greatest, then find the middle number.
3,7,3,2,7,9
2,3,3,7,7,9
There are two middle numbers, so we have to find the middle of the two.
3,4,5,6,7
5 is the median, so the answer is B.

hope it helps
Answer:
B) 5
Step-by-step explanation:
To solve, first list the numbers in numerical order:
2, 3, 3, 7, 7, 9
Now find the middle number(s) of the set:
2, 3, 3, 7, 7, 9
It's between 3 and 7, so find the middle of these two numbers:
3, 4, 5, 6, 7
The final answer is 5!

The ratio of boys to girls in a class is 5:7. There are 36 students in the
class. How many more girls than boys are there?
Answers
Answer: number of girls = 21 & number of boys = 15
21 - 15 = 6 ( the difference is 6 )
Step-by-step explanation:
Answer:
add the ratios together. this gives 5+7 which is 12. divide 36 by 12, this gives 3. this tells us it's three students for every value of the ratio, so the ratio is 5(3):7(3). it becomes 15 boys to 21 girls. to find out how many more girls, we subtract 15 from 21. our answer is 6.

3) [tex]x^{2}[/tex] + 4x - 21
Step-by-step explanation:
(x - 3)(x + 7)
Distribute:
x(x + 7)
-3(x + 7)
x(x) = [tex]x^{2}[/tex]
x(7) = 7x
-3(x) = -3x
-3(7) = -21
Combine like terms:
7x - 3x = 4x
Put it together:
[tex]x^{2}[/tex] + 4x - 21
Answer: x²+ 4x - 21
Let's do this step-by-step.
1. Apply the foil method. (formula: (a + b)(c + d) = ac + ad + bc + bd)
F - First
O - Outer
I - Inner
L - Last
= xx + x × 7 + (-3)x + (-3) × 7
2. Apply the minus and plus rules. + (-a) = -a
xx + 7x - 3x - 3 × 7
3. Simplify.
Convert xx into a exponent.xx ⇒ x²Subtract 7 by 3.7x - 3x = 4xMultiply 3 by 7.7 × 3 = 21Hence, the answer is x² + 4x - 21
