Answer:

-6-(-1)

Step-by-step explanation:

Since all the boxes are negative, and there are 6 boxes, the first part of the equation is -6. Then since the last box is being taken away, we are subtracting it. The last box is still negative though so the last part is -1. Since -6 subtracted by -1 is -6-(-1), the answer is:

-6-(-1)

Can someone help me 14. Determine the arc length. Give your answer to two decimal places.

Paul [167]

Answer:

19.48 m

Step-by-step explanation:

The formula that is used to find arc length is:

arc length = 2πr $(\frac{angle}{360})$

In this question, r = 9m and the angle (θ) = 124°. Substitute the values into the formula.

arc length = 2 × π × 9 × $(\frac{124}{360})$

= 2 × π × 9 × 0.3444

= 19.48 m

Linear equation 4.5 + 1.5y=24 x-y=4

WARRIOR [948]

4.5x + 1.5y = 24 ⇒ 4.5x + 1.5y = 24
1.0x - 1.0y = 4 ⇒ 4.5x - 4.5y = 18
 6y = 6
 6 6
 y = 1
 4.5x + 1.5(1) = 24
 4.5x + 1.5 = 24
 - 1.5 - 1.5
 4.5x = 22.5
 4.5 4.5
 x = 5
 (x, y) = (5, 1)
