Look at the fact that there are 45 marbles first. There is no clue just how many blues there might be. but there should not be as many as 18. The only way you can solve this is with a proportion. You can also ask yourself if Jon draws 45 instead of 60 times, how many marbles will he draw.

18/60 = x / 45 Cross multiply
18*45 = 60*x
810 = 60x
810 / 60 = x
x = 13.5

He can't draw 1/2 a marble. The answer is either 13 or 14 depending on what you have been told about rounding. Statistically I would pick 13 because it is  a conservative choice.

Marcs is growing three bean plants as part of a science experiment. Plant A 1/3 inch tall. Plant B is 3/4 inch tall. Plant C is
snow_tiger [21]
Shortest to tallest: Plant A, Plant B, Plant C.

Given:
Plant A 1/3 inch tall
Plant B 3/4 inch tall
Plant C 5/6 inch tall

Order from shortest to tallest.

First we need to get the least common multiple of the three fractions.

Multiple of 3: 3, 6, 9, 12
Multiple of 4: 4, 8, 12, 16
Multiple of 6: 6, 12, 18

Their least common multiple is 12. We need to multiply each fraction by the number that will give the product of 12 to the denominator.

Plant A: 1/3 * 4/4 =   4/12
Plant B: 3/4 * 3/3 =   9/12
Plant C: 5/6 * 2/2 = 10/12

Since the denominator is common, we will use the numerator as basis in ordering the plants from shortest to tallest. 

4 is less than 9 and 9 is less than 10.

so, Plant A is the shortest, Plant B is the medium height, and Plant C is the tallest.

A rectangle has a width of 10cm. The rectangle length is 4 times its width
Nana76 [90]

Answer:

P = 100 centimeters (assuming you are asking for the perimeter)

Step-by-step explanation:

P = 2 (L + W) OR P =  2L + 2W where P equals the perimeter, L equals the length, and W equals the width.

Since the rectangle's length is 4 times its width and given we know the width is 10 centimeters, then the length is 40 centimeters. Now we can substitute these values in our formula, okay?  

P = 2 (L + W)  

P = 2 (40 + 10)  

P = 80 + 20  

P = 100 centimeters

Frosty Whip Inc. budgets 65 percent of its total expenses for marketing. Total expenses for the company this year are $500,000.
Misha Larkins [42]

65% of the total expenses is for marketing, in which 500,000 is the total.

First, change the percentage into decimal

65% = 65/100 = 0.65

Next, to find the amount budgeted for marketing, multiply the total with the decimal

0.65 x 500000 = 325000

$325000 is used for marketing

hope this helps

-377 = x - 1,000 i dont under stand it
Naddika [18.5K]

Answer:

\boxed {x = 623}

Step-by-step explanation:

Solve for the value of x:

-377 = x - 1,000

-Switch sides:

-377 = x - 1,000

x - 1,000 = -377

-Add 1,000 on both sides:

x - 1,000 + 1,000 = -377 + 1,000

\boxed {x = 623}

Therefore, the value of x is 623.
