Lee can type 1 1/3 pages every 15 minutes. How many hours does it take him to type 10 2/3 pages? Complete the rate table to solve the proportion.

pages---> 4/3=32/3
hours---> 1/4 = x

Lee can type 10 2/3 pages in _________ hours.
a. 1 3/4
b. 2
c. 2 1/4
d. 2 1/2

Answers

Answer:

First, we know that:

1 1/3 = 4/3

10 2/3 = 32/3

15 minutes = 0.25 hours

Let's imagine that x (hours) is the time it takes Lee to type 32/3 pages.

From the information, we can tell that:

Lee can type:

4/3 pages in 0.25 hours

32/4 pages in x hours

So x should be:

x = (32/4 . 0.25)/4/3 = 2 (hours)

So it takes Lee 2 hours ro type 10 2/3 pages

Correct Answer : B

Explanation 4:7 | 4*4 = 16 | 7*4 = 28

Answer:

16:28

Step-by-step explanation:

The answer is 16:28 because if we reduce it to its lowest terms we get 4:7.

To reduce it to its lowest terms we divide both sides by 4 :

16 / 4 = 4 AND 28 / 4 = 7

So 16:28 is the right answer.

The area of a rectangular parking lot is 24 square yards.

Which of the following could NOT be the dimensions of the lot?

12 yards by 3 yards

1 yard by 24 yards

4 yards by 6 yards

3 yards by 8 yards

Answers

12 yards by 3 yards. You need to find the area and see if it is 24. Area is length times width.
12x3 is 36
1x24 is 24
4x6 is 24
3x8 is 24
The only one that isn’t 24 is 12 by 3. Hope this helps.

Answer: (A) 12 yds by 3 yds

Explanation:

To find the answer to this problem, you should go through your list of possible solutions and determine which one will not equal 24 square yards. To determine which one will and will not equal 24, you will have to multiply each solution.

12 • 3 = 36
1 • 24 = 24
4 • 6 = 24
3 • 8 = 24

All but one of our answer is 24, therefore 12yds by 3yds is our answer, because 12 times 3 is 36.

*Side Note*
Considering the part of the question “The area of a rectangular parking lot is 24 square yards.” 1 yard is equivalent to 3 feet, so in retrospect, answer (B) 1 yard by 24 yards, or a 3 foot by 72 foot parking lot would not physically work considering that you typical car is about 5.8 feet wide. No car would be able to fit in that parking lot.

Answer:

x = 19

Step-by-step explanation:

We can see that the angles (2x + 4) and (8x - 14) are supplementary — they add to 180. From this observation, we can form the equation that can be solved for x:

(2x + 4) + (8x - 14) = 180

↓ combining like terms

10x - 10 = 180

↓ adding 10 to both sides

10x = 190

↓ dividing both sides by 10

x = 19

what is the product of -16 x -5 x -11?
please give an answer and explanation

Answers

Answer: -880

Step-by-step explanation:

This is based on the fact that 2 negatives equals a positive and 1 negative + 1 positive equals a negative.

First, you would multiply two of the three numbers, I did -5 * -11 as it seemed like the easiest. Two negatives makes a Positive so that's: -5 * -11 = 55. Now you can do 55 * -16. One Negative and One Positive makes a Negative so the answer is -880. You can use column method or whatever method you use to multiply two digit numbers but I would always think of it as two different equations.

Hope this is an okay explanation!

Step-by-step explanation:

All of the little cubes have side length 2" Thus, the 11" height of the box cannot be used entirely: we waste the top 1" because the five layers of little cubes reach only to 10" from the bottom.

Start at the bottom of the box. The dimensions of the bottom are 12" by 8". Along the longer side we can lay 6 blocks (which add up to 12" and are 2" wide. We can add 3 more such rows to fill the available 8" width of the box bottom. That's 6*4, or 24 blocks.

We can add 4 more 6 block by 4 block layers before we have the maximum 5 layers stacked in the box.

5 layers times 24 blocks per layer comes to 120 blocks total.

The graph will be plotted as +1.4 on the right side of the number line.

What is number line?

The visual representation of numbers on a straight line, either horizontally or vertically, is known as a number line. When numbers are put down on a number line, it is straightforward for people to compare them and perform basic arithmetic operations on them.

One says that a number line starts at zero (0). There are only negative numbers to the left of zero and only positive numbers to the right of zero. In other words, as we move to the right on a number line, the value of the numbers increases.

Given number: -7/5 = -1.4.

As, all negative numbers are lies on the left side of the number line.

To mark the point on the opposite side then we definitely have to mark this point on right side of the number line i.e., +1.4

Hence, the point +1.4 or +7/5 should be placed on the right side of the number line.

Point A' is located at (-5,4)
Point A is located at (4,5)
Point A' is located at (-4,5)

Answers

The correct answer is Point A' is located at (-5, -4).

When a point is reflected in the y-axis, its x-coordinate is negated and its y-coordinate remains the same. Therefore, the x-coordinate of point A changes from +5 to -5, and the y-coordinate remains -4. Hence, the coordinates of A' are (-5, -4).
