Answer: -2/3
3-(-1) over
-2-4
This equals 4/-6 which reduces to -2/3
Answer:
The length of the arc GH is approximately 3.14 meters (or π)
Step-by-step explanation:
The length of an arc whose measure equals the measure of the central angle Ф and the radius of the circle r is:
Let us solve the question using the rule above
∵ The measure of arc GH is 30°
∴ Ф = 30°
∵ The radius is 6 meters
∴ r = 6 meters
→ Substitute them in the rule above
∵ L = (30° ÷ 360°) × 2π × 6
∴ L = × 12π
∴ L = π
→ Use π ≈ 3.14
∴ L ≈ 3.14
∴ The length of the arc GH is approximately 3.14 meters (or π)
Answer: there were 19 five dollar bills and 17 20 dollar bills.
Step-by-step explanation:
Let x represent the number of five dollar bills that were received.
Let y represent the number of twenty dollar bills that were received.
Parts of the proceeds from a garage sale was $435 worth of five dollars and $20 bills. This means that
5x + 20y = 435 - - - - - - - - - - -1
If there were two more five dollar bills than $20 bills, it means that
x = y + 2
Substituting x = y + 2 into equation 1, it becomes
5(y + 2) + 20y = 435
5y + 10 + 20y = 435
25y = 435 - 10 = 425
y = 425/25 = 17
x = y + 2 = 17 + 2
x = 19
Answer:
The answer is 6(3 + 4)
Step-by-step explanation:
In order to find this, we must find the greatest common factor of both numbers. Below are the factors for each number.
18: 1, 2, 3, 6, 9, 18
24: 1, 2, 3, 4, 6, 12, 24
You'll notice that the highest number on both lists is 6. So we divide each number by 6 and then express as a distribution.
6(3 + 4)
30% times 450 = 135
450 - 135 = 315
