An automatic doughnut machine can produce 1500 doughnuts in 9 hours.
How long would it take the machine to make 300 doughnuts?

Answers

Answer:

1 hr, 48 minutes

Step-by-step explanation:

you can create a proportion:

doughnuts/hours = doughnut/hours (h)

1500/9 = 300/h

cross-multiply to get:

1500h = 2700

h = 27/15

h = 1 12/15, which is 1 hr, 48 minutes because 12/15 = 48/60

8. Makayla and Haylee are selling oranges for a school fundraiser. Customers can buy small boxes of oranges and large boxes of oranges. Haylee sold 6 small boxes and 12 large boxes for a total of $330. Makayla sold 12 small boxes and 4 large boxes for a total of $280. a. Write a system of equations that gives the cost of one small box of oranges and one large box of oranges.

b. Find the cost of a small box of oranges and the cost of a large box of oranges

Answers

Answer:

x = 55 - 2y

y = 70 - 3x

x = 17

y = 19

Step-by-step explanation:

let x = small box

y = large box

6x + 12y = 330

12x + 4y = 280

6x + 12y = 330

6x = 330 -12y

6x/6 = (330-12y)/6

x = 55 - 2y

12x + 4y = 280

4y = 280 -12x

4y/4 = (280 -12x)/4

y = 70 - 3x

small box cost:

x = 55 - 2y

x = 55 - 2(70-3x)

x = 55 -140 + 6x

x - 6x = -85

-5x = -85

x = 17

large box

y = 70 - 3x

y = 70 - 3(17)

y = 70 - 51

y = 19

Answer:

The name given to the shaded region would be the positive interval because all f(x) values in that region are positive.

Y=-3(x-4)+3x
Find f(-1)
Can someone solve and explain please? No Bots No Links.

Answers

Answer:

Step-by-step explanation:

while f(x) = f(-1) then we can solve the equation

Y=-3(x-4)+3x

f(x)=-3(x-4)+3x

f(-1)=-3(x-4)+3x

=-3((-1)-4)+3(-1) = 12

What is m
A) 34
B) 56
C) 60
D) 62
E) 124

Answers

Answer:

Since it is symmetrical, the angles will be the same on both sides.

So EFG = 56*

And 180* - 56* = 124*

And 124* / 2 = 62*

So m<FEG = 62*

Answer:

A:Tina's. B: Gabby's

Step-by-step explanation:

Luckly the two people are using the same unit to measure both time (in weeks) and height (in inches), so no conversion needed.

At this point, let's start dealing with the questions.

A. They bought the plants at week 0.

For Tina, we calculate [tex]f(0) = 0+1.5 = 1.5[/tex]

For Gabby, we scout the table till we find week 0 and check the corrisponing value: it's (0; 1) Since 1 is smaller than 0, at start Tina plant was taller.

B. The easiest way would be to stare at Gabby's table for a bit, and notice that each increase is 2 more than the previous, and the progression starts at 1. We can write it as an equation as [tex]g(x) = 2x+1[/tex]. If you confront with Tina's growth, you can tell that Gabby's plant grows twice as fast - the slope is double. Else, you can see that even just after one week, Tina's plant will be 2.5 in tall, while Gabby's outgrew hers already. That's possible only if the plant is growing faster.

Jill cut 26 apples today. 12 of those apples were red. The rest were green. What is the ratio of red to green apples?

Answers

Answer:

7 : 6 is the ratio

Step-by-step explanation:

14 apples were green and 12 apples were red, so divide both terms by 2.

14 ÷ 2 = 7

12 ÷ 2 = 6

Therefore:

14 : 12 = 7 : 6.

26-12=14

12 Red
14Green

think of it as a fraction

12/14

find a common denominator (2)

12/14= 6/7

so the ratio is actually 6:7 because it says “what is the ratio of red to green apples” that means they want it in that order.

any help plz ??? thx in advance you'll get brainliest

Answers

Answer:

For (a)

Well let “x” be amount of sales

And let ”y” be total pay

so 1200 is the base pay/ weekly

And a 5 percent commission on amount of sales

5 percent can be written as 0.05

Now we can make an equation

1200+0.05x = Y

So that would be your equation

Now for (b)

If she sold 10,000 that week as commission we can just plug it into our equation

1200+0.05(10,000)=y

Now solve

5 percent of 10,000 is 500 dollars.

Now 1200+500=1700

(b) is 1700 earned that week

Now for (c)

We want to know How much should be sold in order for a 3000 income. We’re finding amount of sells.

So same equation

1200+0.05x=3000

x=36,000 have to be solve in order to make 3,000 income Per week.
