Use the net to find the surface area of the regular pyramid.
Number only. NO UNITS!
Answer:
40 in.²
Step-by-step explanation:
First, you have to find the area of the triangle, which you then multiply by 4 (because there are 4 triangles):
A=1/2(bh)
A=1/2(3x4)
A=1/2(12)
A=6
6x4=24 in.²
Next, you have to find the area of the square:
A=bh
A=4x4
A=16
Now, add 24 and 16 together to get your answer of 40 in.².

In a cheerleading competition, each team receives scores in eight categories. One team has an average score of 7.25 in the eight categories. Write a division equation in the "Show Your Work" box and then solve algebraically to find the team’s total score s. Place your final answer in the space provided.
The total teams score in competition are 58.
Based on the condition, the solution to find the total teams score:
- Given the identify of variables:
Mean Score: 7.25/team
Categories : 8
Total team score: s
- Formulated the variables become equation properly:
s = Mean score x Categories
s = 7.25 x 8
s = 58
- Hence, The total teams score in competition are 58.
Equation
Equation refers to a mathematical expression containing the equals sign. Algebra is frequently used in equations. In mathematics, algebra is employed when the exact value of a calculation cannot be determined.
An equation is merely a numerical statement that can substitute a variable for an unknown value. A variable is a letter that is used to represent an unknown value. It can be any letter, although the letter x is the most common.
All formulas are equations. Some equations are not formulas. Equations are intended to be solved for a certain variable.
The variable of this problem is mean score, categories and total score. From this variable, identify each function to find the equation then the result.
Determine which expression is equivalent to the expression 5 over 4 times g minus 3 minus 7 over 12 times g minus the expression one over 3 times g plus 15.
negative 1 over 3 times g plus negative 18
negative 4 over 12 times g plus negative 12
4 over 12 times g plus negative 18
16 over 12 times g plus negative 12
The equivalent expression is negative 1 over 3 times g plus negative 18.
Option A is correct.
How do we calculate?We follow the simplification process:
5/4 * g - 3 - 7/12 * g - 1/3 * g - 15
(5/4 - 7/12 - 1/3) * g - 3 - 15
Find common denominator:
(15/12 - 7/12 - 4/12) * g - 18
4/12 * g - 18
fraction reduction and we arrive at: 1/3 * g - 18
Note:
Reducing fractions means simplifying a fraction, wherein we divide the numerator and denominator by a common divisor until the common factor becomes 1.

Question 14 (1 point)
A local bakery called "Becky's Bakery" makes 100 batches of cookies in 8 hours. If they keep up this
pace, how many batches of cookies would they make in 12
hours
Answer:
150 = x
Step-by-step explanation:
We can use a ratio to solve
100 batches x batches
------------------- = ---------------------
8 hours 12 hours
Using cross products
100 * 12 = 8x
1200 = 8x
Divide by 8
1200/8 = 8x/8
150 = x
Answer:
150
Step-by-step explanation:
Find how many batches in one hour
100/8 = 12.5
Multiply 12 hours with 12.5 batches
12 x 12.5 = 150
So, in 12 hours 150 batches are made.

Complete the table. At the beginning of the summer, there are 15 rabbits living in a field. Each week for the rest of the summer, another rabbit moves in. The equation r=25 + w describes the number of rabbits, r, after a certain number of weeks, w

(image displayed below)
Based on the above, there are 26 rabbits after 1 week.
There are 33 rabbits after 8 weeks.
What is the numbers of Rabbits?Weeks Since Summer Started Rabbits
1 | 16
2 | 17
3 | 18
4 | 19
5 | 20
6 | 21
7 | 22

To find the number of rabbits after a certain number of weeks, we can substitute the number of weeks into the equation r = 25 + w and solve for r.
For example, after 1 week, we have:
r = 25 + w = 25 + 1 = 26
So there are 26 rabbits after 1 week.
Similarly, after 8 weeks:
r = 25 + w = 25 + 8 = 33
So there are 33 rabbits after 8 weeks.

Find the infinite geometric sum of 4+2.4+1.44+...
Answer:
4+2.4=6.4+1.44=7.84
The infinite geometric sum of 4+2.4+1.44+... will be 10.
What is the common ratio?At each point in the sequence, you multiply or divide by the common ratio. Divide two sets of phrases that follow one another to find it. Whichever pair of terms is picked, as long as they appear next to one another in the sequence, is irrelevant.
It is given that, the sequence is 4+2.4+1.44+...
The sequence is defined as the systematic way of representing the data that follows a certain rule of arithmetic.
Divergent sequences are those in which the terms never stabilize; instead, they constantly increase or decrease as n approaches infinity, approaching either infinity or -infinity.
It is obtained that the common ratio is,
r=2.4/4
r=0.6
The Sum of an infinite geometric sequence is,
S = a / (1-r)
S=4 / (1-0.6)
S=10
Thus, the infinite geometric sum of 4+2.4+1.44+... will be 10.

2. You put 15x in the first part and 10 in the second part. Answer is 15x + 10.
You are pretty much multiplying 5 times 3x in the first part of the box and 5 times 2 in the second part of the box.
3. 7x in the first part of the box and -63 in the second part of the box. Ans. 7x - 63.
4. 30x + 45
You are just doing 5 times 6x and 5 times 9 since 5 is outside the parentheses and 6x and 9 are inside it.
5. 12k - 8

7. 4 - 3j

Negative 12 (from 6 times 2) and positive 10 are added together to make 2 (since it says to combine any like terms.

18b and 5b are added together since they are like terms.

Find the diagonal of the box, AD, using the Pythagorean Theorem twice - 1. To find BD and 2. To find AD.
AB = 12 in
BC = 18 in
CD = 4 in
Show all steps for findin the diagonal of the box above using the formula instead of the Pythagorean Theorem twice.
Answer:
BD = √(18² +4²) = √340; AD = √(12² +(√340)²) = 22AD = √(12² +18² +4²) = 22Step-by-step explanation:
You want the space diagonal of the given box (a) using the Pythagorean theorem twice, and (b) using the formula.
Pythagorean theorem twiceThe length of BD can be found from ...
BD² = BC² +CD²
BD² = 18² +4² = 340
BD = √340 ≈ 18.439
and
AD² = AB² +BD²
AD² = 12² + 340 = 484
AD = √484 = 22
The lengths of the face and space diagonals are ...
BD = √340 ≈ 18.439AD = 22FormulaNo formula is given as part of the problem statement. We can simplify the above calculations to get ...
AD² = AB² +BD²
AD² = AB² +BC² +CD²
AD = √(AB² +BC² +CD²) . . . . . . a reasonable formula
AD = √(12² +18² +4²) = √(144 +324 +16) = √484
AD = 22
