Answer:
Step-by-step explanation:
123/6 x 7[(654 + 2) x (12/3)].....do whats in parenthesis first
123/6 x 7[656 x 4] ......do whats in brackets
123/6 x 7(2624) ....do multiplication/division from left to right, whichever comes first
20.5 x 18,368 =
376544 <===
15 fluid ounces.
1quart= 4 cups
Answer:
30%
Step-by-step explanation:
(plastic beads)/(beads on clearance) = 6/20 = 30/100 = 30%
_____
A percentage is a representation of a fraction that has 100 as a denominator. The percent sign (%) is just a shorthand way to write "divided by 100" (/100). The word "percent" means "per hundred", or "divided by 100."
Here, the given fraction (6/20) can be multiplied by 5/5 to make it have a denominator of 100.
Answer:
5
Step-by-step explanation:
check the picture below on the top side.
we know that x = 4 = b, therefore, using the 30-60-90 rule, h = 4√3, and DC = 4+8+4 = 16.

now, check the picture below on the bottom side.
since we know x = 9, then b = 9, therefore DC = 9+6+9 = 24, and h = b = 9.
