Desmond builds a set of towers out of blocks. The table shows the number of blocks in each tower. Tower # 1 2 2 3 4 5 Number of blocks 5 10 20 40 80 Which explicit formula correctly represents the number of blocks, an, in terms of the tower number, n? A. an = n + 80 B. an = 2n + 5 C. An = 5(2)n-1 D. an = 10(5)
Answer:
C. An = 5(2)^n-1
Step-by-step explanation:
Tower 1 2 3 4 5
Number of blocks 5 10 20 40 80
Where,
n = tower number
An = number of blocks
A. an = n + 80
B. an = 2n + 5
C. An = 5(2)^n-1
D. an = 10(5)^n
Checking all options
A. An = n + 80
When n = 1
An = 1 + 80
= 81
B. An = 2n + 5
When n = 1
= 2(1) + 5
= 2 + 5
= 7
C. An = 5(2)^n-1
When n = 1
= 5(2)^1-1
= 5(2)^0
2^0 = 1
= 5(1)
= 5
D. An = 10(5)^n
When n = 1
= 10(5)^1
5^1 = 5
= 10(5)
= 50
The explicit formula which correctly represents the number of blocks, an, in terms of the tower number, n is C. An = 5(2)^n-1

The sum of 13 and a number x is equal to 15.
Use elimination to solve and match each system of equations to the correct solution.
5x+12y=-34
2x+4y=-12
Answer:
x = -2 y= -2
Step-by-step explanation:
5x+12y= -34
2x+ 4y = -12
2x= -4y -12
x= -2y -6
plug back in
5(-2y -6) +12y = -34
-10y -30 +12y = -34
2y = -4
y= -2
2x+4y=-12
4y= -2x -12
y= -.5x -3
plug back in
5x+ 12(-.5x-3)=-34
5x -6x -36 = -34
-x = 2
x= -2
Answer:
Step-by-step explanation:
5x + 12y = -34
-6x - 12y = 36
-x = 2
x = -2
5(-2) + 12y = -34
-10 + 12y = -34

Answer:
D) 3x + 15 ≥ 300
Step-by-step explanation:
The rectangle must have a area of AT LEAST 300 square ft, or 300 or greater. Use the greater than or equal sign: ≥ 300.
Note that your are solving for the area, and that this shape is a rectangle. To get the area of the rectangle, simply multiply length and width:
(3) * (x + 5) = Area of rectangle.
Distribute the 3 to all terms:
3(x + 5) = 3x + 15 = Area of rectangle.
Put the two parts together:
3x + 15 ≥ 300.
~
Answer:
The last answer.
Step-by-step explanation:
The area of a rectangle is
Area=(width)*(length)
If we substitute the 2 given values into the formula we will get
Area= 3(x+5)
=3x+15
Since it's asking that it has to be "at least 300", it's saying that the equation has to be 300 or more.
3x+15>(less than or equal to) 300.
Point E is between segment DF. The length of DE is 3x - 1, EF is 13 and DF is 6x, find DF.
Answer:
The correct answer to this problem is x = 4.
Step-by-step explanation:
To solve this problem, we can set up an equation using the given information. We know that Point E lies along the segment DF, so we can write:
DE + EF = DF
Now, we can substitute the values given into our equation.
(3x-1) + (13) = 6x
The next step is to eliminate the parentheses and combine like terms on the left side of the equation.
3x - 1 + 13 = 6x
3x + 12 = 6x
Next, we should subtract 3x from both sides to move all of the variable terms to the right side of the equation.
12 = 3x
Finally, we can divide both sides by 3, in order to completely isolate the variable x on the right side of the equation.
4 = x
Therefore, the correct answer is x = 4.
Hope this helps!
Twice the sum of a number and 3 is equal to three times the difference of the number and 7. Find the number
Answer:
The number is 27
Step-by-step explanation:
Let us change the word statement to an algebraic equation
→ Assume that the number is x
→ Twice the sum of a number and 3, means add x by 3, then multiply the sum by 2
→ The algebraic expression is 2(x + 3)
→ Three times the difference of the number and 7, means subtract x and 7, then multiply the difference by 3
→ The algebraic expression is 3(x - 7)
→ Equate the two expressions
∴ 2(x + 3) = 3(x - 7)
→ Simplify each side
∵ 2(x + 3) = 2(x) + 2(3) = 2x + 6
∵ 3(x - 7) = 3(x) - 3(7) = 3x - 21
∴ 2x + 6 = 3x - 21
Let us solve the equation to find x
→ Subtract 6 from both sides
∴ 2x + 6 - 6 = 3x -21 - 6
∴ 2x = 3x - 21
→ Subtract 3x from both sides
∴ 2x - 3x = 3x - 3x - 27
∴ -x = -27
→ Divide both sides by -1
∴ x = 27
The number is 27
why is the following conditional logically true? If 20 is a multiple of 3, then 101 is a perfect square
Answer: A number is a perfect square only if it has a odd number
Step-by-step explanation:
As an example of the use of the prime factorization of an integer, we have the following result. Theorem. If n > 1 is a positive integer, then n is a perfect square if and only if n has an odd number of divisiors.
Since 20 is not a multiple of 3 it means the given statement is wrong so 101 is a perfect square that will be correct.
What is the reasoning?The procedure of utilizing logical reasoning to analyze a condition to determine the best problem-solving approach for a particular issue, then using this approach to create and explain a resolution.
In another word, reasoning is a tricky but interesting problem in mathematics that required relations of variables to solve.
Given the first statement
20 is multiple of 3
Since 20/3 given remainder of 3 so it is not multiple.
So the first statement is wrong.
So if the question is saying this it means the question will consider all correct statements as wrong.
Now,
101 is a perfect square is wrong but the question will consider it correct.
Hence "Since 20 is not a multiple of 3 it means the given statement is wrong so 101 is a perfect square".

cm?
A. 54 sq. cm B. 54 cm
C. 30 cm
D. 30 sq. cm
Answer:
The answer is option CStep-by-step explanation:
Perimeter of a rectangle = 2l + 2w
where
l is the length
w is the width

Solve -4(3x – 7) = 52 for x.
Answer:
x = -2
Step-by-step explanation:
First, distribute:
-12x + 28 = 52
Then, subtract 28 on both sides:
-12x = 24
Finally, divide -12 on both sides:
x = -2
Hope this helps!
Answer:
Your answer is x= -2
Step-by-step explanation:
[tex]-4(3x-7)=52[/tex] divide both sides by -4
[tex]\frac{ -4(3x-7)}{-4} = \frac{52}{-4}[/tex] cross out -4 and divide 52 by -4= -13

Consider this equation 2,900 = 250 + 132.5T. In this situation, what would the solution
to this equation tell us?
Answer:
T = 20Step-by-step explanation:
Given the equation 2,900 = 250 + 132.5T, to get the solution of the equation, we will find the value of T as shown;
From 2,900 = 250 + 132.5T
subtract 250 from both sides;
2,900- 250 = 250 + 132.5T-250
2,650 = 132.5T
Divide both sides by 132.5
132.5T/132.5 = 2650/132.5
T = 20
Hence the solution to the equation tells us that the value of T is 20

Professor Slughorn has created and sold three different magical potions where if a person drinks them, he or she magically can fly, breathe underwater, or read minds. He sold ten more flying potions than mind reading potions. The number of breathing underwater potions he counted was two more than three times the number of mind reading potions. If he sold a total number of 102 potions, how many were for breathing underwater?
Answer:
56 underwater breathing potions
Explanation:
Create variables to represent the different potions
- flying = f underwater breathing = b mind reading = m
Make equations to represent all of the information you've been given.
- The number of flying potions is ten more than the number of mind reading potions. f = r + 10
- The number of water breathing potions is two more than three times the number of mind reading potions. b = 3r + 2
- The total number of potions is 102. f+b+r = 102
Substitute the variable in your equation for the total number of potions.
102 = (r +10) + (3r + 2) + r = 102
Combine like terms.
102 = 5r + 12
Solve for r.
90 = 5r
18 = r
You have to find the number of underwater breathing potions, b. Go back the equation for b and substitute 18 for r.
b = 3r + 2
b = 3(18) + 2
b = 56
So, your total number of underwater breathing potions is 56.
The Smith family put a rectangular garden in their back yard. The garden measured 15 34 feet long and 13 13 feet wide. Which is the best estimate of the area of the Smith's garden? Response area
Answer:
201.4 feet
Step-by-step explanation:
Area of a rectangular garden = length × width
Length of the rectangular garden = 15.34 feet
Width of the rectangular garden = 13.13 feet
Area of a rectangular garden = length × width
= 15.34 feet × 13.13 feet
= 201.4142 feet
Approximately 201.4 feet
The Area of the rectangular garden = 201.4 feet
