Math: There are 30 pages in a chapter of your textbook. You read 40%, how many pages do you have left to read? Explain how to solve this using 2 different methods

Answers

12 pages to read left.

Answer:

18 pages left

Way 1: Find what 40% of 30 is and subtracting it from 30, leaving 60% of 30 left:

40% of 30 is 0.4*30 = 12, 30 - 12 = 18

Way 2:  Subtract 40% from 100% and multiply it by 30: 100% - 40% = 1 - 0.4 = .6, 0.6*30 = 18

Answers

Answer:

C

Step-by-step explanation:

Different slopes; same y-intercept

Use a graphing calculator or an online one, like desmos to help visualize

y=x minus 2

y=2x minus 2

y= negative X minus 2

y=negative 2

If you were to type this on a graphing calculator

*Notice how all of these functions intersect at the same point on the y axis . That is because they all share the same y-intercept of -2

* The slopes are all different using the rise over run method.

Slope of y=x minus 2 is 2/2 or 1

Slope of y=2x minus 2is 2/1 or 2

Slope of y=negative X minus 2 is 2/-2 or -1

Slope of y= negative 2 is 0

Answers

Answer: 7/10, 7/10 and 3/10.

Step-by-step explanation:

7/10 = Between 1 and 10, the multiples of three are 3, 6, and 9. So the amount favourable outcomes is the total minus the multiples, 10-3 = 7. So 7/10.

7/10 = Between 1 and 10, the multiples of 2 are 2, 4, 6, 8, and 10. The multiples of 3 are 3, 6 and 9. That, gives 7 favourable outcomes (6 is a multiple of both but counted once) giving the probability of 7/10.

3/10 = The favourable outcome is 8 and above, so: 8, 9 and 10. There are 3 favourable outcomes which gives the probability of 3/10.

You have the 1st one correct...
The second one is 8/10...
The 3rd is 3/10

Four runners completed in a 10-kilometer relay race. Each Runner ran the same distance. What was that distance?

Answers

Answer:

each runner ran 2.5 kilometers

Step-by-step explanation:

10÷4=2.5

The distance would be 2.5 kilometers if four runners completed a 10-kilometer relay race while covering the same distance each.

What is division?

A method of dividing something into equal parts is called division. It produces a fair distribution of resources and is one of the four basic operations in mathematics.

How to solve this problem?

Total distance = 10 kilometers

Total number of runners = 4

Since they all covered the same distance,

the distance = 10/4 = 2.5 kilometers

Therefore, the distance would be 2.5 kilometers if four runners completed a 10-kilometer relay race while covering the same distance each.

Write an equation to describe this situation.

Answers

Answer:

7[tex]l[/tex]=150

Step-by-step explanation:

Each lap is worth $7, so if Mu walked [tex]l[/tex] laps and the total is $150, then the equation would be

7[tex]l[/tex]=150

7l=$150
l= 21.82 so mu would have to walk 22 laps to make $154 ; 21 laps would only make $147 . And there is no such thing as 21.82 laps .
However if you only needed the equation it is 7l=150

Please help me explain as well. AD is 48. I will give brainliest.

Answers

Answer:

The area of the rectangle is 48

Step-by-step explanation:

We know that AE is 6 and ED is 8, since it forms a triangle, use the Pythagorean theorem to find AD, which is one side of the rectangle.

The Pythagorean theorem says that a^2 + b^2 = c^2.

a is AE, b is ED, and c is AD, so 6^2 + 8^2 = c^2, 36 + 64 = c^2, 100 = c^2, 10 = c, so AD is 10

The area of the triangle is half of AE times ED, so 1/2(6)(8) = 1/2(48) = 24, the area of the triangle is 24.

Since the area of a triangle is 1/2 of the base times the height, we can figure out the height:

A = 1/2bh, 24 = 1/2(10)h, 24 = 5h, 4.8 = h, so the height of the triangle (and rectangle) is 4.8.

The height of the triangle is also the height of the rectangle:

The area of the rectangle is 4.8*10 = 48

A worker can load 4 pallets in 30 minutes. At that rate, how many pallets can he load in 4 hours?

Answers

8 pallets each hour so it would be 8 x 4 to find the answer. the answer is 32 pallets

Answer:

32

Step-by-step explanation:

1 hour = 60 minutes

Thus, 30 minutes if half an hour.

The worker can load 4 pallets every 30 minutes.

30*2=60

4*2=8

So the worker can load 8 pallets every 60 minutes, or every hour.

8*4=32

So, a worker can load 32 pallets in 4 hours.

12: 12,24,36,48,60,72
16: 16,32,48,64,80,96
Since 48 is in both, caller number 48 will get both

The caller number will receive both would be 48.

What is Least common multiple?

The Least common multiple of two or more numbers are the smallest number that is multiple of two or more numbers.

Given that;

On a radio morning show, every 12th caller receives concert tickets, and every 16th caller receives an autographed album.

Now,

Since, On a radio morning show, every 12th caller receives concert tickets, and every 16th caller receives an autographed album.

Hence, The common caller number is find by calculating the LCM of 12 and 16.

⇒ LCM of 12 and 16 = 48
