A business held a job fair for prospective employees. The number of women attending was 10 more than three times the number of men attending. A total of 180 people attended the meeting. Which system of equations could be used to find w, the number of women, and m, the number of men, at this meeting?
1. w = m + 10
w + m = 180
2. w = m + 10, , w + m = 180,
3w + m = 10
3. w + m = 180
3w + m = 10, , w + m = 180,
4. w = 3m + 10
w + m = 180

If a baseball travels at 90 mi/h, how many seconds does it take to travel 60 ft.?
Answer:
0.458 seconds
Step-by-step explanation:
dont get mad when its wrong
0.458 seconds
You already know that the ball travels at 90 mi/hr. 60.5 1/475200 = 0.00012732 hours. This is still a small number so express it in seconds. 0.0076389 minutes = 60 0.0076389 = 0.458 seconds. (this from google btw)

Answer:
A. 1.50 dollars per kilogram
B. 1.80 dollars per kilogram.
C. 2.10 dollars per kilogram
D. 2.40 dollars per
kilogram.
Answer:
The average rate will be 2.40 dollars per kg.
Hence, option D is correct.
Step-by-step explanation:
From the table, it is clear that the order size is located on the x-axis and the price is located on the y-axis.
The price of 100 kg cumin = $450
The price of 600 kg cumin = $1650
so
at x₁ = 100, f(x₁) = 450
at x₂ = 600, f(x₂) = 1650
Using the formula to determine the average rate of change at which the total cost increases will be:
Average rate = [f(x₂) - f(x₁)] / [ x₂ - x₁]
= [1650 - 450] / [600-100]
= 1200 / 500
= 2.4
Therefore, the average rate will be 2.40 dollars per kg.
Hence, option D is correct.

A large multiplex movie house has many theaters. The largest theater has 50 rows. There are 12 seats in the first row. Each row has two seats more than the previous row. How many total seats are there in this theater?
Answer:
a(50) = a(1)+ (50-1)d = 20 + 34*2 = 20+78 = 98
Ans: S(50) = (n/2)(a(1)+a(50)) = (50/2)(20+98) = 50*59 = 1365

In a shopping district with a variety of stores, 9 of the stores sell jewelry. The jewelry stores make up only 3% of the shopping district. How many stores are in the shopping district?
Answer:
When I did this in middle school, the teacher made it unnecessarily difficult (-_-), so here`s my own method for you.
Finding 1%:
If 9 is 3%, then 3 is 1%. This method only works when the sides are divisible.
You can use the 1% to find the total, which is 100%.
3 stores (or 1%) x 100 = 300.
There are 300 stores in the shopping district.

Answer:
7. y = f(x +2) -7
8. y = -f(x -5)
9. y = f(-x) +3
Step-by-step explanation:
The general transformation can be written ...
y = a·f(b·(x -c)) +d
'a' is the vertical expansion factor. A negative value means the graph is reflected over the x-axis.
'b' is the horizontal compression factor. A negative value means the graph is reflected over the y-axis.
'c' is the number of units of right-shift.
'd' is the number of units of up-shift.
__
7. 2 left and 7 down means (c, d) = (-2, -7), so the transformed function is ...
y = f(x +2) -7
__
8. reflected over x and 5 right means (a, c) = (-1, 5), so the transformed function is ...
y = -f(x -5)
__
9. reflected over y and up 3 means (b, d) = (-1, 3), so the transformed function is ...
y = f(-x) +3
_____
The graph shows an asymmetrical function that makes it possible to tell what the transformations are. The original is dashed orange. The various y-values correspond to the problem numbers. You can see that the transformations match the problem statements.
Anan is researching hummingbirds, one of the smallest birds. He measures Hummingbird A 2 3/4 tall while hummingbird B measures 2 4/10 tall. How much larger is hummingbird A than humming bird B?
Answer:
3.5/10 taller
Step-by-step explanation:
3/4 is 0.75 and 4/10 is 0.40
0.75-0.40=0.35
0.35 can also be written as 3.5/10 or 35/100
Tom drove at a constant speed of 50 miles per hour for 2.5 hours.
Albert drove at a constant speed of 65 miles per hour for 2 hours.
Who drove farther? How many more total miles did he drive?
Use the equation d =r xt to solve.
drove farther. He drove
more total miles.
Answer:
Albert by 5 more miles
Step-by-step explanation:
Tom: 50 * 2.5 = 125 miles
Albert: 65 * 2 = 130 miles
Albert drove for more miles
130-125 = 5 miles
Albert drove for 5 more miles
Introduction to nonlinear models
Complete the table below.
Answer:
The table will be:
x y = 2x² y = 2ˣ
0 0 1
1 2 2
2 8 4
Step-by-step explanation:
Given the non-linear equations
y = 2x²
y = 2ˣ
When x = 0y = 2x²
y = 2(0)² =0
y = 2ˣ
y = 2⁰ = 1
When x = 1y = 2x²
y = 2(1)² = 2
y = 2ˣ
y = 2¹ = 2
When x = 2y = 2x²
y = 2(2)² = 8
y = 2ˣ
y = 2² = 4
Thus, the table will be:
x y = 2x² y = 2ˣ
0 0 1
1 2 2

three times the sum of n and four is twelve. write an equation or inequality.
9514 1404 393
Answer:
3(n+4) = 12
Step-by-step explanation:
The sum of n and 4 is (n+4). Three times that sum is 3(n+4). When we say it "is 12", we mean it is equal to 12.
3(n +4) = 12
