Find the area of the shaded region

helpp!!

Answers

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

There are 8 footballs in a store cupboard; one is yellow and the others are
white. A pupil takes 2 footballs out of the cupboard at random. What is the
probability that one of them is the yellow ball?

Answers

⚾️= white football (. I know It’s not)
= Yellow football( same thing)

⚾️⚾️⚾️⚾️⚾️⚾️⚾️
We could re-arrange this many ways max 8 but with white each one has 8
Soo 8•7 equals 56
There is a chance in 56 times they only get the yellow ball 8 times but the white one would be chosen most of the times.

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.

Answers

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.

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.

Answers

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

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.

Answers

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

Pls just answer it for me, i have been having a horrible day like so bad, been working on this for like hours and hours. My mind might explode.

Answers

a. Erin basically put 2 units to the right and 4 units down. Since x would be going left or right and y up or down, Erin did not write the rule correctly.

b. The correct transformation rule would be (x, y) (x - 4, y + 2). When going to the left, you would be subtracting and going up would be adding, hope this helped!

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:

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.

Answers

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 :)

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).

Answers

8,160.. but rounding would be 8170 sooo both increased by 5 and 9 percent would be 1270 and 1507 !

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%.
