i uh need help its easy
Answer:
C
Step-by-step explanation:
Answer:
c)
Step-by-step explanation:
so we know that the total amount of students in said school is 180, which means that the total amount of girls in this school cannot be greater than 180
with that, let us get to solving these equations to see which one is less than 180-
a) 85/10*180=1530>180
b) 850/100*180=1530>180
c)0.85*180=153
'c' is the only answer choice less than 180>153
another way to solve this would be to focus solely
on answer choice 'c'-
so 85% of the school is female and 85% as a fraction is 0.85, and we need to find the total amount of girls that attend said school and the only way to do that is to multiply-
0.85*180=153>180
good luck :)
i hope this helps

Tonya sampled 35 customers leaving the grocery store to find out how long they spend shopping. The results were that two people spent less than 15 minutes shopping, 28 people spent between 15 minutes and an hour shopping, and five people spent over an hour shopping.
Inference: Most customers spend less than an hour shopping.
Defend or challenge the inference with at least two complete sentences.
Answer:
challenge because it said 28 people spent between 15 and an hour if that is so the could have been there for an hour so there
Step-by-step explanation:
Answer:
The inference makes an incorrect statement.
Step-by-step explanation:
It is said that Tonya sampled 35 customers, where 28 of them spent 15-60 minutes, and 5 people spent over 60 minutes. This means that there are already 5 people that shop for over an hour. There may also be a bigger portion of shoppers that shop for exactly 60 minutes (1 hour), which is NOT less than 1 hour.

Answer:

Step-by-step explanation:
A sign says that the price on all music equipment is 30% off the original price. you buy an electric guitar for the sale price of $315.
A-what is the original price?
B-How much money did you save off of the original price?
C-What percent of the original price is the sale price?
Answer:
a. So the electric guitar is sold for a sale price of $315 after the discount. The discount was 30%. Even though we get that amount off, we still pay 70% of the original price, because 100% (original price) - 30% is 70%.
b. An equation that can help us find the regular price of the item is through writing and solving a proportion. Set it up like this:
315/x = 70/100
This is because 315 is part of the whole and is 70% of the value of x.
Step-by-step explanation:
Okay. Let's solve this by cross multiplying the values. 315 * 100 is 31,500. 70 * x is 70x. That simplifies to 31,500 = 70x. Didivde each side by 70 to isolate the x. 70x/70 cancels out. 31,500/70 is 450. Let's check this by multiply the number by 70% and see what happens. 450 * 70% (0.7) is 315. There. x = 450. The regular price was $450.
Answer:
a. $450
b. $135
c. 70%
Step-by-step:
[tex]\frac{70}{100} = \frac{315}{450}[/tex] since these two fractions are equal to each other that means the orginal price is $450.
(sale price/original price)x100= % of original price
(315/450)x100=0.7=70%
At his favorite restaurant, Dylan orders a soda with his dinner. The ice in his drink has a mass of 6 g and a volume of 20 cm3. What is the density of the ice? Explain the steps you took to solve this problem.
Answer:
0.3
Step-by-step explanation
The formula to find density is m/v=p
m=mass
v=volume
p=density
---------------------------All we have to do is plug in 6g and 20cm^3
This will give us 6/20 which simplifies to 3/10
With this you can easily figure out that the decimal for 3/10 is 0.3
So the density of the ice is 0.3

Find the area of the shaded region
helpp!!
Answer:
1. 116 m
2. 60 cm
Step-by-step explanation:
1. The total area is 12*10 m, or 120 m. The area of the non-shaded region is 7*2 m, or 14. Subtract 14 from 120 to get 116.
BTW the side 12 looks like it is less than the 10, the question is not lengthed properly, just saying
2. A bit trickier, divide the question into 2 parts, a triangle and rectangle.
The rectangle is 12*4 cm, or 48 cm, the triangle is 12 - 3 - 3 = 6 and 8 - 4 = 4
So we use 6 and 4. The area of a triangle is 1/2b * h, half of the base times the height, the base is 6 cm, and the height is 4 cm, 1/2(6) * 4 = 3*4 = 12 cm
48 + 12 = 60 cm

the following graph shows the number of soccer games a team won in each of their three seasons. Explain how you could redraw the graph so the change in wins between the three seasons does not seem so great.
Answer:
you can instead draw a 4x3 graph, and just shrink the width to make it look like there was a bigger dip in between seasons. so season 1 would be under the first box, the second season under the second box, and the third season under the third box. this would then make the slope downward to therefore make the graph look like a bigger drop

An investor has an account with stock from two different companies. Last year, his stock in Company A was worth $5660 and his stock in Company B was worth $2500. The stock in Company A has increased 5% since last year and the stock in Company B has increased 9%. What was the total percentage increase in the investor's stock account? Round your answer to the nearest tenth (if necessary).
The total percentage increase in the investor's stock account will be 8.6%.
What is the percentage?The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates for one hundred percent. It is symbolized by the character '%'.
The percentage is given as,
Percentage (P) = [Final value - Initial value] / Initial value x 100
The amount he earned from company A and company B is given as,
Earned = $5660 x 0.05 + $2500 x 0.09
Earned = $283 + $225
Earned = $508
Then the total percentage increase in the investor's stock account is given as,
P = [(508) / (5660 + 2500)] x 100
P = (508 / 5910) x 100
P = 0.086 x 100
P = 8.6%
The total percentage increase in the investor's stock account will be 8.6%.

A local gym sells monthly memberships. The function f(x) = −x2 + 18x − 72 models the daily profit in dollars, where x is the number of memberships sold.
Determine the zeros, and explain what these values mean in the context of the problem.
x = 9, x = 18; The zeros represent the number of monthly memberships that produces a maximum profit.
x = 9, x = 18; The zeros represent the number of monthly memberships where no profit is made.
x = 6, x = 12; The zeros represent the number of monthly memberships that produces a maximum profit.
x = 6, x = 12; The zeros represent the number of monthly memberships where no profit is made.
Answer: C.) x = 6, x = 12; The zeros represent the number of monthly memberships that produces a maximum profit. Is not the answer
Step-by-step explanation: I took the test and got it wrong. I don't know what the answer is.
x = 6, x = 12; The zeros represent the number of monthly memberships that produce a maximum profit. The correct option is C.
What is a quadratic equation?It is a polynomial with a degree of 2 or the maximum power of the variable is 2 in quadratic equations. It has two solutions as its maximum power is 2.
Given that a local gym sells monthly memberships. The function f(x) = −x² + 18x − 72 models the daily profit in dollars.
The given quadratic equation is solved by equating the function to zero:-
−x² + 18x − 72 = 0
x² - 18x + 72 = 0
x² - 12x -6x + 72 = 0
x ( x -12 ) -6 ( x -12 )= 0
( x - 12 ) ( x - 6 ) =0
x = 12, 6
Therefore, x = 6, x = 12; The zeros represent the number of monthly memberships that produce a maximum profit. The correct option is C.
