Answer:

It will take 4.71 hours to travel a distance of 221.43 miles

Step-by-step explanation:

Given

Distance covered in time 7.99 hours is 375.32 miles.

Now we know that speed is equal to distance per unit time.

Therefore,

$speed = \frac{distance}{time} \\= \frac{375.32}{7.99}\\=46.97\ mi/h$

Which is the constant speed, hence now time taken for a distance of 221.43 miles will be

$time = \frac{distance}{speed} \\=\frac{221.43}{46.97} \\=4.71\ h$

Therefore, the time taken to cover 221.43 miles is 4.71 hours.

Cora sliced 18 \text{ kg}18 kg18, start text, space, k, g, end text of apples for a party. She divided the apple slices equally

Vikentia [17]

Answer:

Cora put 3600 apple slices in each bowl.

Step-by-step explanation:

Cora sliced 18 kg of green apples for a Party.

She divided the Apple slices equally between 5 large bowls.

We need to find how many grams of Apple slices did Cora put in each bowl.

Since,

1 kg = 1000 grams

18 kg = 18000 grams

To find how many grams of Apple slices did Cora put in each bowl, divide total apples by total no of bowls.

$x=\dfrac{18000}{5}\\\\=3600$

Hence, Cora put 3600 apple slices in each bowl.

list the following rational numbers in order from least to greatest. -0.4 , 0.48, 4/8, -4/8. Someone plssssssss help me I need i

Lostsunrise [7]

For a problem like this, it is best to convert all numbers to a similar form making them easier to compare. I am going to convert them all to decimals, although converting them all to fractions can also work.
-0.4 is already a decimal, so it needs no conversion; the same goes for 0.48.
4/8 is equal to 1/2, which equals 0.5 as a decimal. -4/8 is the same as -1/2, which is -0.5.
Therefore, we are left with the following converted numbers:
-0.4; 0.48; 0.5; -0.5

Now to simply order them from least to greatest, we will start with the two negative numbers because they are both below zero. When comparing negative numbers, the "bigger" one is actually smaller because it is farther below zero. Therefore, -0.5 is the smallest, followed by -0.4.

Now for the last two, 0.5, or 0.50, is 0.02 bigger than 0.48. Therefore, 0.48 is the second largest number and 0.5 is the largest.

This is the order now:
-0.5 (smallest)
-0.4 (2nd smallest)
0.48 (2nd largest)
0.5 (largest)

Now they simply need to be converted back to their original form (if applicable):
-0.5 = -4/8
-0.4 = -0.4
0.48 = 0.48
0.5 = 4/8

This leaves us with the answer:
-4/8; -0.4; 0.48; 4/8
