Fourteen less than three fourths of a number is negative eight. Find the number

1 answer:

8 0

The word "is" in this kind of problem typically means "=", so we know that something =-8. Since we're finding the number, we should start with the closest thing in the phrase given to that number. In this case, it's 3/4x. Finally, since we have the "14 less than", we need to add that in. Your answer is:

3/4x-14=-8. Now we can just solve!
+14 +14

3/4x=6.
*4/3 *4/3

x=8.

Cammie can mow 1/2 acre in 25 minutes. If her rate is constant, Cammie says she can mow 1 1/4 acres in one hour. Is Cammie corre

wlad13 [49]

Answer: No, Cammie is not correct. She can mow $1\frac{1}{5}\ acres$ in one hour (See explanation).

Step-by-step explanation:

Convert the mixed number to an impoper fraction:

1. Multiply the whole number part by the denominator of the fraction and add the product to the numerator.

2. The denominator does not change.

Then:

$1\frac{1}{4}=\frac{(1*4)+1}{4}=\frac{5}{4}$

Let be "x" the acres Cammie can mow in one hour.

You know that she can mow $\frac{1}{2}\ acre$ in 25 minutes, then you can set up the following proportion (Remember that 1 hour has 60 minutes):

$\frac{\frac{1}{2}}{25}=\frac{x}{60}$

Solving for "x", you get:

$\frac{\frac{1}{2}}{25}=\frac{x}{60}\\\\(60)(\frac{1}{50})=x\\\\x=\frac{6}{5}$

Convert from improper fraction to mixed number:

1. When you divide 6 by 5, the quotient is 1. This will be the whole number part.

2. The remainder is 1. This will be the numerator.

3. The denominator does not change.

Then:

$x=1\frac{1}{5}$

Therefore, she can mow $1\frac{1}{5}\ acres$ in one hour.

laiz [17]

Answer:

there are 331 full boxes but the one box that isnt full has two melons

Step-by-step explanation:

2,650 divided by 8 = 331

331 multiplied by 8 = 2648

2650 - 2648 = 2

so there are 332 boxes total 331 full ones and one not full on with 2 melons in it.

a) change 7 out of 50 to a percentage. b) change 18 out of 20 to a percentage .

Ber [7]

7 out of 50 is the same as 7/50

First, change the fraction into a decimal by dividing.

7 / 50 = 0.14

Second, change the decimal into a percentage by multiplying by 100%.

0.14 * 100% = 14%

18 out of 20 is the same as 18/20

First, change the fraction into a decimal by dividing.

18 / 20 = 0.9

Second, change the decimal into a percentage by multiplying by 100%.

0.9 * 100% = 90%

Best of Luck!

Step-by-step explanation:

Assume the height of the streetlamp to be x

If you make a diagram from the details given by the question you should find two pairs of similar sides, from which you can form the equation

$\frac{x}{6} = \frac{20+5}{5}$

Solving this gives the height of the streetlamp as 30 feet. Divide this length by the height of the man to get the number of times the streetlamp is taller.
