Step-by-step explanation:
250,000 x 24 x 3
Answer:
155
Step-by-step explanation:
2325 / 15
15 goes into 2325 155 times.
2.02, 2.03, 2.2, 2.22, 2.23, 2.3 is the correct order.
The triangles in question 15 are proportional, so they are similar. Meaning that their angles are the same, so <B=<E, or <B=30 degrees.
For #17, the formula for the area of a circle is a=pi*r^2. The radius, in this instance, is 1/2 of 27, or 13.5. Plug it into the formula: a=pi*13.5^2. a=pi*182.25. If you want to simplify it further, a=572.265.
#19, same formula as #17. a=pi*r^2. a=pi*6^2. a=pi*36. a=113.04 or 113m^2.
#20, Wow this is a complicated one. Anyway, the area of the square in the middle is obviously 9m. The area of all of the circles is a=pi*1.5^2 DIVIDED BY TWO, since they're half circles. a=pi*2.25/2, a=7.065/2. a=3.5325. Since there are 4 of them, multiply that number by 4... 14.13. Add 9 to that to get the area of the whole figure: 23.13m(^2). Hope this helps.
24 cans/ 96 people = x cans/28 people
using cross products
24 * 28 = 96 *x
divide by 96 on each side
24*28/96 = x
672/96=x
7=x
You will need 7 cans
or
96/24= 4 people per can
28 people /4 people per can = 7 cans
