Jill can walk 6 miles in 1 hour . how long will it take her to walk in 8 miles

2 answers:

7 0

The answer is easy. Divide 1 hour by 6 and you get ten minutes. So subtract 6 from 8 and you have 2 so now you do 2 multiplied by 10 which is 20 so your answer would be an hour and 20 minutes

Evaluate the expression -7 1/4x + 3 5/8 for x= -4

Misha Larkins [42]

Answer:

32 5/8 (or 32 and 5/8)

Step-by-step explanation:

Okay, so this problem is asking for us to solve this problem with the substitution of a variable: x = -4. Before we fully solve this problem, we need to replace all of those x variables with -4 so that it is easier to solve.

-7 1/4(-4) + 3 5/8.

To make this problem even easier to solve, let's turn these mixed numbers into improper fractions. To do this, multiply the denominator by the whole number. Then add the numerator to this number. The new number that you just got is now your new numerator for this number.

-29/4(-4) + 3 5/8.

Repeat the last step to turn the other mixed number into an improper fraction.

-29/4(-4) + 29/8.

Now let's multiply that -4 by 29/4. Because a whole number technically has a denominator of 1, we can now set up the next part of our problem. (The symbol * means multiplication since we can't use x since it is already being used as a variable in this equation.)

(-29/4 * -4/1) + 29/8.

29 + 29/8.

Now to solve the rest of this problem, let's convert the whole number of 29 so that it has a denominator of 8. This is that these two numbers are addable.

29 x 8 = 232

1 x 8 = 8

Now these numbers are addable. So:

232/8 + 29/8 = 261/8 = 32 5/8.

I hope that this helps.

Hey can you please help me posted picture of question

Sergeeva-Olga [200]

Total number of chips = 4+ 6 = 10
Number of white chips = 4

Probability of picking a white chip = $\frac{4}{10}= \frac{2}{5}$

This white chip is not replaced back into the bag. This will reduce the number of white chips in the bag by 1 and reduce the total number of chips in the bag by 1.

So, now the total number of chips in the bag = 3 + 6 = 9
Number of white chips in the bag = 3

Probability of picking a white chip = $\frac{3}{9}= \frac{1}{3}$

Thus, the probability of picking two white chips will be = $\frac{2}{5}* \frac{1}{3}= \frac{2}{15}$

Therefore, option B gives the correct answer.

Match the amounts and tip or tax rates in the first column to the total costs in the second column.

gogolik [260]

Answer:

1. $132.24

2. $55.89

3. $1336.66

4. $258.19

5. $57.86

Step-by-step explanation:

Simply use this equation.

$\frac{InitialValue}{100} = \frac{x}{TaxPercentage}$

Substitute in our values, using No.1 as our example.

$\frac{123.01}{100} = \frac{x}{7.5}$

Cross multiply

922.575 = x100

Solve for x by dividing by 100.

x = 9.22575

Now add x to the initial value.

9.22575 + 123.01 = 132.23575

Round to the nearest hundredth for the answer.

$132.24
