Answer:
160
Step-by-step explanation:
If there were only 2 options, all the people who didn't pick one chose the other one.
So if 25% of the people voted for the aquarium the remaing 75% voted for the zoo.
Since three times as many people voted for the zoo, we can see that 120/3=40, so 40 people chose the aquarium.
To find the total number of students, we add 120 and 40 to get 160

A rental car costs $15 a day plus 25 cents for each mile driven. Which
expression shows the cost to rent a car for 1 week and drive 200 miles?
A. (15.25 x 7) + 200
B. (0.25 x 7) + (15 x 200)
C. (15 x 7) + (0.25 x 200)
D. 15 + (0.25 x 200
The expression that shows the cost to rent a car for 1 week and drive 200 miles is (15 × 7) + (0.25 × 200)
The problem can be modelled to a linear equation.
Linear equationLinear equation can be represented in slope intercept form as follows:
y = mx + b
where
m = slope
b = y-intercept
Therefore,
y = total cost of the rental
x = mile driven
Hence,
y = 0.25x + 15
Therefore, the expression that shows the cost to rent a car for 1 week and drive 200 miles is as follows:

Find the slope and the y-intercept of the line.
Y=2-1/3x
Slope:- -1/3
y-intercept:- 2
Solution:-The equation of the line is written in slope-intercept form, which looks like this:- y=mx+b.In this formula, m stands for the slope, and b stands for the y-intercept of the line.In this case, the equation looks like this:- y=b+mxHowever, it does not matter. m is still the slope and b is still the y-intercept.Also, you should notice that the slope is the coefficient of x (the number next to x) and b is the constant (a number added/subtracted to/from the slope)Therefore, the slope of the line is equivalent to:--1/3And the y-intercept is equivalent to the following:-2Hope it helps.
Do comment if you have any query.
Answer:
Slope: -1/3
Y-intercept: 2
Explanation:
The equation y = 2 - 1/3x is in slope-intercept form.
The format of slope intercept is y = mx + b, where m = slope and b = y-intercept.
The slope is the coefficient of x.
Hence, the slope of y = 2 - 1/3x is -1/3.
As for the y-intercept, that is the constant.
The constant in y = 2 - 1/3x is 2. Hence, the y-intercept is 2.
(7-2)² - 5 / 5 I dont get the exponent part can someone help me with whole problem
(7-2)² - 5/5
Do the math in the parentheses first.
7 - 2 = 5
Now the equation should read
(5)² - 5/5 or just 5² - 5/5
Do the exponent(s).
5² = 25
25 - 5/5
Do the division.
5/5 = 1
25 - 1 = 24
Therefore, according to our equation, the answer is 24.

A mobile set after allowing a discount of 10% on its marked price, was sold at a gain of 20%,Had it been sold after allowing 20% discount,there would have been a profit Rs.350. Find the cost price and marked price of the mobile set.
Answer:
Let x be the cost price.
Let y be the marked price
Gain = 20%
Then , sale price = 120/100 * x = 1.2x
Now , sale price is after 10% discount from marked price.
Hence , marked price, y = 1.2x/90 * 100 =
y * 0.9 = x * 1.2
Now, with 20% discount, sale price = y * 80/100 = 0.8y
Now, profit = 0.8y — x
Now, 0.8y — x = 350
0.8 * x * 1.2/0.9 — x = 350
1.0667x — x = 350
Hence, x = 350/0.0667= Rs.5250
Hence marked price = (5250 + 350) * 100/80 = Rs.7000

She billed a customer $104, but forgot how long she worked. To solve for the number of hours, she subtracted 50 from 104 and then divided by 18.
Answer:
Cora worked 3 hours
Step-by-step explanation:
104 = 18x + 50 ( x = # of hours worked)
54 = 18x ( subtracted 50 from both sides)
3 = x ( divided both sides by 18)

Jasmine's credit card has a $2,000 balance that she carried over from last month. assuming her credit card charges an 18 percent annual interest rate, how much will her interest charges be this month?
Using simple interest, it is found that her interest charge this month will be of $30.
Simple InterestSimple interest is used when there is a single compounding per time period.
The amount of interest after t years in is modeled by:
I(t) = Prt
In which:
P is the initial amount.r is the interest rate, as a decimal.In this problem, considering the time in years, the parameters are:
[tex]P = 2000, r = 0.18, t = \frac{1}{12}[/tex]

What is the polygon being Rotated to create the blue quilt block pattern
As shown, to obtain the blue quilt block pattern, we have to rotate the parallelogram.
What is parallelogram?A parallelogram is a quadrilateral consisting of pairs of parallel sides.
To obtain the blue quilt block pattern, we have to rotate the parallelogram. This rotation allows the parallelogram to take on a new orientation, and when it is positioned correctly, it creates the blue quilt block pattern. The process of rotating the parallelogram may seem simple, but it is a critical step in achieving the desired quilt design. It requires attention to detail and precision to ensure that the parallelogram is correctly rotated, and the resulting blue quilt block pattern is aligned correctly.
Moreover, the correct rotation of the parallelogram can significantly impact the overall appearance of the quilt, and even a slight misalignment can make a noticeable difference. Therefore, it is important to carefully follow the instructions to rotate the parallelogram to achieve the intended blue quilt block pattern.

if ey/n + k = t, what is y in terms of e, n, k, and t?
1) y= tn+k/e
2) y= tn-k/e
3) y= n(t+k)/e
4) y= n(t-k)/e
Answer:
option 4
Step-by-step explanation:
To write in terms of y
Step 1: subtract k from both sides
[tex]\sf \dfrac{ey}{n} + k - k = t -k\\\\\\\dfrac{ey}{n}=t-k[/tex]
Step 2: Multiply the entire equation by n
[tex]\sf n*\dfrac{ey}{n}=n*(t-k)\\\\\\ey=n(t-k)[/tex]
