2. On a blueprint for a new building, 2 inches = 8 feet. The height of the building on the
blueprint is 9 inches. What is the actual height of the building?
Step-by-step explanation:
By blue print conversion,
2 inches = 8 feet
Therefore, 1 inch = [tex]\frac{8}{2}[/tex] = 4 feet
1 inch = 4 feet
The height of the building on the blueprint = 9 inches
The actual height of the building = 9 * 4 = 36 feet.
The measure of angle W is 100°, and the measure of angle Z is 68°.
A triangle has angles X, Y, Z. The exterior angle to angle X is W.
What is the measure of angle Y?
Answer:
32 degrees
Step-by-step explanation:
The interior and exterior of X must equal 180 degrees.
X + W = 180
Plug in 100 for W and subtract it from both sides.
180 - 100 = X = 80 degrees.
The total of the internal angles of a triangle are 180 degrees.
80 + 68 + Y = 180
Solve for Y: Y = 180 - 68 - 80 = 32 degrees.

What could describe Anita’s race from minute 3 to minute 5?
Answer:
b) She stopped to change a flat tire.
Step-by-step explanation:
I'm assuming the y-axis of the graph says distance.
Over time, Anita did not move at all which indicates that she stopped. There is nothing to do with speed in this question do you can take out answers a) and d). c) is pretty irrelevant because why would Anita continue riding her bike after if she already won. So the answer is b) She stopped to change a flat tire.

a. x2 + y2 + 16x - 8y + 73 = 0
c. x2 + y2 + 16x + 8y + 73 = 0
b. x2 + y2 + 8x - 4y - 73 = 0
d. x2 + y2 + 8x + 4y + 73 = 0
Please select the best answer from the choices provided
Answer: A) x2+y2+16x-8y+73=0
Step-by-step explanation:
I got it right on edge.
The generic version of the circle equation is, x² + y² + 16x - 8y + 73 = 0.
Definition of circle:
A circle is a closed two-dimensional object in which all points in the plane are equidistant from a single point known as the "centre." The line of reflection symmetry is formed by every line that travels through the circle. For any angle, it also exhibits rotational symmetry around the center.
Step-by-step:Step 1:
The conventional form of the circle equation is expressed as:
(x - a)² + (y - b)² = r²
where centers are specified as (a,b)
The circle equation given in the question is:
x² + y² = 7
If the circle is translated T(-8,4), the center of the translated circle is located at (-8,4).
As a result, the conventional version of the circle equation is:
(x + 8) ² + (y - 4) ² = 7
Step 2:
Simplifying the problem:
(x² + 64 + 2(x)(8)) + (y² + 16 - 2(y)(4)) = 7
x² + 64 + 16x + y² + 16 - 8y = 7
x² + y² + 16x - 8y + 80 = 7
x² + y² + 16x - 8y + 80 - 7 = 0
x² + y² + 16x - 8y + 73 = 0
which is the generic version of the circle equation.

Jesse played two days of golf. On the second day, he got a score of 6 below par, or −6. His total score for the two days was 0 above par, or 0. Define a variable. Then write and solve an equation to find the score Jesse got on the first day. Show your work.
Answer:
6
Step-by-step explanation:
The total of the two days adds up to 0. So define x as the score of the first day, and then have the equation x - 6 = 0.
Then solve,
x - 6 (+6) = 0 (+6)
x + 0 = 6
x = 6

The population in a small town is increasing annually by 1.8%. What is the quarterly rate of population increase
Quarterly Rate means the per annum interest rate to be determined for the Bonds on a quarterly basis and the quarterly rate of population increase [tex]0.00447[/tex].
What is quarterly?
If the rate of interest is annual and the interest is compounded quarterly then the number of years [tex](n)[/tex] is [tex]4 times[/tex] and the rate of annual interest [tex](r)[/tex] is one-fourth.
Here given that the annual rate is [tex]r=0.018[/tex].
And the exponential growth function is
[tex]y=a(1+r)^{x} ...(1)[/tex]
where [tex]a[/tex] is the initial amount
and [tex]r[/tex] is the rate of growth.
So, By equation [tex](1)[/tex], we get
[tex]y=a(1+0.018)^{t}\\y=a(1.018)^{t}[/tex]
The quarterly growth rate, the exponent is the number of quarters in [tex]t years[/tex] or [tex]4t[/tex].
So, by multiplying the exponent by [tex]\frac{4}{4}[/tex], the [tex]4t[/tex] represents the number of quarters
[tex]i.e., y=a(1.018)^\frac{4t}{4}\\y=a(1.018^\frac{1}{4})^{4t}\\y=a(1.00447)^{4t}\\[/tex]
Hence, the quarterly growth rate is [tex]1.00446[/tex], now we subtract it with [tex]1[/tex] so it is of the form:-
[tex]1.004477-1=0.00447[/tex]
which implies that the population is increasing.

5x 2 + 10x - 40
Answer:
(x + 4)(x - 2)
Step-by-step explanation:
For factoring when there's a coefficient on the leading variable, I use the "slip n' slide" method (my teacher called it that, I had no part in naming it), but when that fails, you can use the quadratic formula.
First, you "slip" the leading coefficient to the end, and multiply.
5x² + 10x - 40
x² + 10x - 200
Now, you factor it normally.
x² + 10x - 200
= (x + 20)(x - 10)
Then, you divide the 2nd part in each parentheses with the coefficient you slipped in the beginning. This is super important! I always had trouble remembering this step, so hopefully you won't.
(x + 20/5)(x - 10/5)
= (x + 4)(x - 2)

Answer:
A) 9
Step-by-step explanation:
15 - 3(6 - 4)
= 15 - 3(2)
= 15 - 3 x 2
= 15 - 6
= 9
The given expression is equivalent to 9 The correct answer is option A) 9.

15 - 3(2)
Step 2: Next, perform the multiplication:
15 - 6
Step 3: Finally, do the subtraction:
9
The correct answer is option A) 9. The explanation shows how we first evaluate the expression inside the parentheses (6 - 4), then perform the multiplication (3 times 2), and finally subtract the result (6) from the initial value (15) to get the final answer of 9.

Line segment A A prime has a midpoint at point F. Line segment C C prime has a midpoint at point G. Which statement is true about point F? F is the midpoint of AA' because Line E G bisects AA'. F is the midpoint of EG because AA' bisects EG. F is the midpoint of AA' because AA' bisects EG. F is the midpoint of EG because Line E G bisects AA'.
Answer:
It's A - F is the midpoint of AA' because Line E G bisects AA'

Explain how you find m∠3 if m∠5 = 130° and m∠4 = 70°. *
Answer:
The required measure of angle 3 is 60°.
Step-by-step explanation:
We are given to find the measure of angle 3 from the figure if
m∠5 = 130° and m∠4 = 70°.
Let the measure of angle 3 be x°.
From the figure, we note that
angle 5 is an exterior angle and angles 3 and 4 are two remote interior angles of the triangle.
We know that
the measure of an exterior angle to a triangle is equal to the sum of the measures of two remote interior angles.
So, we get
Thus, the required measure of angle 3 is 60°.
Arturo starts saving for college by opening a savings account and depositing $50. He plans to make a deposit every month to continue saving.
The amount of money in Arturo's savings account can be modeled by the sequence A0=50, An=An−1 + 25, where n is the number of months since his initial deposit.
What is the domain of the sequence An?
Answer:
The sequence is a function
Step-by-step explanation:
where n is the number of months since his initial deposits, and A₀=50
The sequence is a function because its domain is a set of natural numbers.
For example,
A₁=A₀+25 =75
A₂=A₁+25=100
A₃=A₂+25=125
A₄=A₃+25=150
The domain is 0, 1, 2, 3, 4, 5,.....
The set of all non-negative integers.
Given sequence is [tex]A_{0}=50, \ A_{n}=A_{n-1}+25[/tex]
Domain of this sequence is n = the number of months since the initial deposit.
The possible values of n = 0, 1, 2, 3, 4, 5,..... It means the set of all non-negative integers.
