Compare 5 yd to 5 ft, 7in to 3ft, 3ft to 50in, 21ft to 4 yd, 9yd to 9in, 36in to 3ft

Answers

We know that

1 yard = 3 feet = 36 inches

To solve these types of problems, it's easiest to convert the number into one unit, and then compare.

1) Compare 5 yards to 5 feet

Let's convert to feet.

5 yards * 3 feet per yard = 15 feet
5 feet = 5 feet

Because 15 > 5, we know that 5 yards > 5 feet.

2) Compare 7 inches to 3 feet.

Let's convert to inches.

7 inches = 7 inches
3 feet * 12 inches per foot = 36 inches

Because 36 > 7, we know that 3 feet > 7 inches.

3) Compare 3 feet to 50 inches.

Let's convert to inches.

3 feet = 36 inches (we already did this above)
50 inches = 50 inches

Because 50 > 30, we know that 50 inches > 3 feet.

4) Compare 21 feet to 4 yards.

Let's convert to feet.

21 feet = 21 feet
4 yards * 3 feet per yard = 12 feet

Because 21 > 12, we know that 21 feet > 4 yards.

5) Compare 9 yards to 9 inches.

For this problem, we don't need to do any calculations.
We know that a yard is bigger than an inch, and therefore because there are equal amounts of these units, 9 yards > 9 inches.

6) Compare 36 inches to 3 feet

Let's convert to inches.

36 inches = 36 inches
3 feet * 12 inches per foot = 36 inches

Because 36 = 36, we can conclude that 36 inches = 3 feet.

In a stairway, the slope of the handrail is the ratio of the riser to the tread. If the tread is 12 inches long and the riser is 8 inches long, find the slope.(image)

a.
2/5
c.
2/3
b.
3/2
d.
5/2

Answers

The slope of the handrail is 2/3. The correct answer is: c. 2/3

To find the slope of the handrail, we can use the given information that the slope is the ratio of the riser to the tread.

Slope = Riser / Tread

Given that the tread is 12 inches long (Tread = 12 inches) and the riser is 8 inches long (Riser = 8 inches), we can substitute these values into the formula:

Slope = 8 inches / 12 inches

Now, we can simplify the ratio:

Slope = 2/3

So, the slope of the handrail is 2/3. The correct answer is:

c. 2/3

During the day, the manager of the meat department sold 15.4 pounds of hamburger to one customer and 13.22 pounds to another customer. When the store opened that morning, he had 35.75 pounds of hamburger to sell. How much hamburger does the manager have left to sell? lb

Answers

The total amount of hamburger that the manager of the store in the morning = 35.75 pounds
Quantity of hamburger sold to one customer during the day = 15.4 pounds
Quantity of hamburger sold to another customer during the day = 13.22 pounds
Total quantity of hamburger sold
by the manager during the day = (15.4 + 13.22) pounds
= 28.62 pounds
Then
The quantity of hamburger left in the store to sell = (35.75 - 28.62) pounds
= 7.13 pounds
So 7.13 pounds of hamburger is still left to be sold.
