a rectangle has an area of 651m². One of the sides is 7m in length. Work out the perimeter of the rectangle​

Answers

Answer:

200

Step-by-step explanation:

So first off, let's find the other side.

651 divided by 7 = 93

93 would be the other side measurement. There are two sides that measure 93 degrees, two sides that measure 7 degrees.

93 + 93 + 7 +7 = perimeter

Once we add up like terms, 200

The length of each of the two congruent sides of an isosceles triangle is 3x - 1. The length of the third side is 2x + 1. The perimeter is 55 feet. Which equation does NOT represent the perimeter?

8x - 1 = 55

6x - 2 + 2x + 1 = 55

2 (3x - 1 + 2x + 1) = 55

2 (3x - 1) + (2x + 1) = 55

Answers

Answer: The third choice

Explanation:

This equation does not represent the perimeter.

To write the equation:

2(3x - 1) + (2x + 1) = 55
6x - 2 + 2x + 1 = 55
8x - 1 = 55

Thus, 3 of the choice represent but the the third choice didn’t appear in the equation.

Nick is given $50 on a vacation. He decides to spend $5 a day. Write an equation relating to the amount of money Nick has left, y, and the number of days, x, Nick spends money

Answers

Answer:

y = -5x + 50

Step-by-step explanation:

We'll write the equation in y = mx + b form, where b is the original amount of money (50), and m is the amount of money he spends he each day(5). Since he's spending 5 dollars, that means that 5 dollars is being lost everyday, so m will be -5:

y = -5x + 50

a waterslide has an angle of elevation of 20 degrees whats is the rise for a run of 2.6 m?

Answers

Answer:

Therefore, the rise will be 0.95 m

Step-by-step explanation:

As the waterslide has an angle of elevation of 20 degrees.

Ф = 20°

And we have to determine the rise for a run of 2.6 m.

All we need is to use the trigonometric ratio of tan Ф

Because

tan Ф = rise/run

As

run = 2.6 m

Ф = 20°

so

tan Ф = rise/run

tan (20) = rise/run

rise = tan (20) × 2.6

rise = 0.95 m

Therefore, the rise will be 0.95 m
