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 :)

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

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

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%

The correct transformation rule to translate points two units up and four units to the left is,

(x, y) → (x - 4, y + 2)

We have to given that,

Erin made a mistake when writing a transformation rule to translate points two units up and four units to the left.

Here, Transformation Rule:

(x, y) → (x + 2, y - 4)

Since, We know that,

The correct transformation rule to translate points two units up and four units to the left is,

(x, y) → (x - 4, y + 2)

As, for 2 units up we add 2 in y - coordinate and 4 units left we subtract 4 in x - coordinates.

Answer:

Wendy is filling in party goodie bags with toy cars and helicopters. There are 56 toy cars and 77 helicopters. Each bag must only have either toy car or helicopter - there is no mixing of toys.

Each bag must have the same number of toy cars in it.

Each bag must have the same number of toy helicopter in it.

All bags must have the same number of toys in it.

a) How many bags will contain toy cars?

b) How many bags will contain toy helicopters?

-------------------------------------------------------------------------------------------------------------

Answer:

Think of highest common factor of 56 and 77

Both numbers are divisible by 1, 2, and 7 and the highest common factor is 7

56 ÷ 7 = 8

77 ÷ 7 = 11

There are 8 bags that contain equal numbers of toy cars and 11 bags that contain equal number of helicopter toy

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.

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.

The total percentage increase in the investor's stock account will be 8.6%.

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%.
