Frank believes his bedroom wall measures 12 feet long.
He has a ruler that is 1? feet long.
He uses this ruler to measure his bedroom wall.
Which equation can be used to solve for T,
the number of times he will have to use the ruler to check the length of his bedroom wall?
A. 1? = 12T
B. 1? T = 12
C. 1? + T = 12
D. T – 1? = 12
Answer:
A
Step-by-step explanation:
Answer:
B. 1? T = 12
Step-by-step explanation:
Since the bedroom measures 12 feet long, the answer or the product should be 12 (12 only)
He uses “1?” to measure the bedroom, and we need to know HOW MUCH TIMES he uses it.
So, 1? T will be the equation since we need to know how much times he uses the ruler.
Does anyone understand this? If you do can you please instruct me on how to do it or solve it?

Match each circular flower bed on the left to its circumference and its area on the right. Some answer options on the right will not be used.
Answer:
Bed A --- Third Option
Bed B --- Fifth Option
Step-by-step explanation:
Flower Bed A)
The formula for circumference is:
[tex]C=2\pi r[/tex]
The diameter of A is 10 feet. So, its radius is 5 feet.
Substitute 5 for r. So, the circumference of Bed A is:
[tex]C=2\pi (5)=10\pi\text{ feet}[/tex]
The formula for the area of a circle is:
[tex]A=\pi r^2[/tex]
Substitute 5 for r:
[tex]A=\pi (5)^2[/tex]
Square and simplify:
[tex]A=25\pi \text{ square feet}[/tex]
So, the circumference of Bed A is 10π feet and its area is 25π square feet.
Therefore, match Bed A to the third option.
Flower Bed B)
The radius of Bed B is 6 feet. Again, we can use the circumference and area formulas. Substitute 6 for r for circumference:
[tex]C=2\pi (6)[/tex]
Multiply:
[tex]C=12\pi\text{ feet}[/tex]
Substitute 6 for r for the area formula:
[tex]A=\pi(6)^2[/tex]
Square and simplify:
[tex]A=36\pi\text{ square feet}[/tex]
So, Bed B has a 12π feet circumference and a 36π square feet area.
Therefore, match Bed B to the fifth option.

A pyramid of logs has 2 logs in the top row, 4 logs in the second row from the top, 6 logs in the third row from the top, and so on, until there are 200 logs in the bottom row. Is the pattern an arithmetic sequence? Identify a and d. Write the 50th term of the sequence. Find the total number of logs in the first 10 rows.
Answer:
1) Is the pattern an arithmetic sequence?
Yes it is
2)Identify a and d.
a = First term = 2
d = Common difference = 2
3) Write the 50th term of the sequence.
50th term = 100
4) Find the total number of logs in the first 10 rows.
= 1010 logs
Step-by-step explanation:
Is the pattern an arithmetic sequence?
Yes it is
2) Identify a and d.
A pyramid of logs has 2 logs in the top row, 4 logs in the second row from the top, 6 logs in the third row from the top, and so on,
The formula for arithmetic sequence =
an = a+ (n - 1)d
a = First term
d = Common difference
For the above question:
a = 2
d = Second term - First term
= 4 - 2
d = 2
3) Write the 50th term of the sequence.
Using the formula for arithmetic sequence
an = a+ (n - 1)d
a = 2
n = 50
d = 2
a50 = 2 + (50 - 1)2
= 2 + (49)2
= 2 + 98
= 100
The 50th term = 100
4)Find the total number of logs in the first 10 rows.
Sum of first n terms = n/2(a + l)
n = 10
a = first term = 2
We are told that there are 200 logs in the bottom row, hence:
l = last term = 200 logs
Hence,
Sn = 10/2×[ (2 + 200
= 5(202)
= 1010 logs

what is y when the equation is x^2 - 3xy -4y^2 =0
Answer:
y = 1/8 (5 sqrt(x^2) - 3 x) or y = 1/8 (-3 x - 5 sqrt(x^2))
Step-by-step explanation:
Solve for y:
-4 y^2 - 3 x y + x^2 = 0
Hint: | Multiply both sides by a term to make the coefficient of y^2 positive.
Multiply both sides by -1:
4 y^2 + 3 x y - x^2 = 0
Hint: | Using the quadratic formula, solve for y.
y = (-3 x ± 5 sqrt(x^2))/8:
Answer: y = 1/8 (5 sqrt(x^2) - 3 x) or y = 1/8 (-3 x - 5 sqrt(x^2))

You are buying packages of beads to make bracelets. Each package costs $3 plus 7% tax. You have a gift card for $15, and you plan to use only the gift card to pay for the beads. Which function c(p) represents the total cost, where p represents the number of packages of beads you purchase? What is a reasonable domain?
A. c(p) = 3.21p − 15; {0, 1, 2, 3, 4}
B. c(p) = 3.21p; all nonnegative integers
C. c(p) = 0.07(3p − 15); all nonnegative integers
D. c(p) = 1.07(3p); all nonnegative integers
Answer:
A
Step-by-step explanation:
You must multiply the number your buying by the price then you need to multiply by 1.07 because you need 7% or .07 to get the tax but you want to add that to the old number so you need a 1 in front so the answer is c(p) = 1.07(3p) however you still need the $15 gift card so instead you add the 7% into the three dollars you are multiplying by the number then subtract the 15 dollars because you aren't really paying. The reasonable domain is 0 1 2 3 4 because the number 5 would be over the 15 dollar limit.

The function c(x) = 2.5x + 15 shows the cost, in dollars, to make x necklaces.
What is c(10)?
What is c(15)?
What is the best interpretation of c(20) = 65 in terms of the problem?
Answer:
c(10)=40
c(15)=52.5
Step-by-step explanation:
c(10) means you plug 10 into your x same with (c15) you plug in 15 so for c(10) it would be 2.5(10) + 15 which is 40
The value of c(10) and c(15) is 40 and 65 respectively.
The given function is c(x) = 2.5x + 15.
What is the function?A function is defined as a relation between a set of inputs having one output each. In simple words, a function is a relationship between inputs where each input is related to exactly one output. Every function has a domain and codomain or range. A function is generally denoted by f(x) where x is the input.
Now, c(10)=2.5(10)+15=40
c(15)=2.5(15)+15=52.5
Given c(20) = 65
So, 65=2.5x+15
⇒50=2.5x
⇒x=20
Therefore, the value of c(10) and c(15) is 40 and 65 respectively.

Answer: -17
A function is defined as a relation between a set of inputs having one output each.
The value of the function f(t) = -2t² + 1 at t = -3 is -17.
The domain of the function is -17.
The range of the function is -3.
What is a function?A function is defined as a relation between a set of inputs having one output each.
f(x) = x + 2
At x = 2,
f(2) = 2 + 2 = 4
Domain = 2
Range = 4
We have,
f(t) = -2t² + 1
We need to find for t = -3.
f (-3) = -2 ( -3 )² + 1
[ -3 x -3 = 9 ]
