An automated bakery can produce 230 loaves of bread in 37 minutes. How many minutes will it take to produce 1500 loaves? Round the answer to the next higher whole minute.

Answers

Answer:

242 minutes

Step-by-step explanation:

Create a proportion where x is the number of minutes to make 1500 loaves

[tex]\frac{230}{37}[/tex] = [tex]\frac{1500}{x}[/tex]

Cross multiply and solve for x

230x = 55500

x = 241.3

Round to the next whole minute

= 242

So, it will take 242 minutes to produce 1500 loaves

The number of pedestrian fatalities in the United States declined approximately steadily from 4,795 fatalities in 2006 to 4165 fatalities in 2009.

Find the “average rate of change” of the number of pedestrian fatalities.

Answers

Answer:

Average rate of change = 0.1313 or 13.13% (approx.)

Step-by-step explanation:

Given:

Pedestrian fatalities in 2006 = 4,795

Pedestrian fatalities in 2009 = 4,165

Find:

Average rate of change

Computation:

Average rate of change = [4,165-4,795] / 4,795

Average rate of change = [-630] / 4,795

Average rate of change = 0.1313 or 13.13% (approx.)

Dylan hit the ball 48 out of the 60 times he was up to bat. The rest of the time, he snuck out. Approximately what percent did dylan strike out?

Answers

Answer:

20 percent

Step-by-step explanation:

(I had such a good explanation and accidentally refreshed the page)

So basics

48/60 is in

12/60 is out

Now we focus on out

we know this 12/60 becuase 48 is in and there are 60 tries so 60-48=12

So now 12/60 into a percent

A percent is basically x/100

So we gotta make 12/60 into a fraction with a denominator of 100

SO simplify fto make it easier (try to get it to 4,2,5,10,50,25 anything that goes into 100)

1/5

1/5 is 20 percent

thats a benchmark

But if you don’t know

You can always do a pro proton

1/5=x/100

Cross multiply

100=5x

x=20

How many angle measurements do you need to figure out the measurements of all the labeled angles in the figure below?

Answers

Answer:

2

Step-by-step explanation:

There are 2 angles measurements do you need to figure out the measurements of all the labeled angles in the figure.

What is mean by Angle?

An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.

Given that;

There are 4 angles is shown in figure.

Now, If we know the value of angle 1 then by vertically opposite angle the value of angle 3 is same as angle 1.

And, If we know the value of angle 2 then by vertically opposite angle the value of angle 4 is same as angle 2.

Thus, There are 2 angles measurements do you need to figure out the measurements of all the labeled angles in the figure.
