the lines are parallel, so you can set the two expressions equal to each other:

2x + 5 = 3x - 10

x - 10 = 5

x = 15

then plug in x to the angle next to y: 2(15) + 5 = 35°

180 - 35 = 145°

What is the approximate area of the shaded sector ?

Answers

Answer:

7.5 cm²

Step-by-step explanation:

Area of shaded sector = θ/360 × πr²

Where,

θ = 180° - 84° = 96°

r = ½(6) = 3 cm

Area of shaded sector = 96/360 × π × 3²

Area = 7.53982238 ≈ 7.5 cm²

Answer:

The first error occurs in Step 3

The value of the equation is -69

A tool box has the dimensions of 9 in by 5 in by 6 in. If Kimberly plans to double one dimension to build a larger tool box, she believes she would double the volume of the tool box. Is she correct?

Answers

Answer:

She is correct.

Step-by-step explanation:

First, multiply 9 * 5 * 6 (original)

9 * 5 * 6

45 * 6

270 in³

Next, multiply 18 * 5 * 6 (if the length was doubled)

18 * 5 * 6

90 * 6

540 in³

Now divide 540 by 270.

540/270

2

Since the volume doubled, Kimberly is correct.

(You could do this for the other two and Kimberly is still correct.

If width was doubled

9 * (5 * 2) * 6 = 9 * 10 * 6

9 * 10 * 6 = 90 * 6

540

If height was doubled

9 * 5 * (6 * 2) = 9 * 5 * 12

45 * 12

540

540/270

Its hard to run in Florida woods, where every square foot not occupied by trees is bristling with thigh-high palmetto spears and nets of entangling skunk vine, but I did my best, calling my grandfathers name and sweeping my flashlight everywhere. I caught a white glint out of the corner of my eye and made a beeline for it, but upon closer inspection it turned out to be just a bleached and deflated soccer ball Id lost years before. I was about to give up and go back for Ricky when I spied a narrow corridor of freshly stomped palmettos not far away. I stepped into it and shone my light around; the leaves were splattered with something dark. My throat went dry. Steeling myself, I began to follow the trail.
