NEED HELP FAST Find the arc length of the partial circle

Mathematics
1 answer:
Nookie1986 [14]3 years ago
6 0

Answer:

The arc length is about 12.57.

Step-by-step explanation:

Formula for arc length: 2πr( degrees/360)

For ours lets do 2π8(90/360)

Simplify the 90 and 360: 16π(1/4)

This gives you: 16π/4

Divide by 4

You get: 4π

4π ≅ 12.57

Please help.. nobody will help me and I’ve been asking this question so many times but nobody will answer..

Answer:

The floor covers 81yd^{2}

Step-by-step explanation:

This question is actually easier than you think, but I am here to help.

First off you know the room is a square. All squares have equal sides no matter what, that is the number 1 basic rule. (27ft by 27ft)

1. Find the area of the square: To find area you multiply Length by Width. Since you are multiplying two units you will get a squared value. The square measures 27 ft by 27 ft on both sides.

Lets multiply those two numbers:

(27 * 27) = 729ft^{2}

We need to stay in the same unit because you are multiplying two values of the same unit. The total square feet of the room is 729ft^{2}

2. Next, all you need to do is convert ft^{2} to yd^{2}

Like you mentioned: (1 yd^{2}  = 9ft^{2})

Now lets create a proportion between the two unit:

\frac{729ft^{2} }{1} * \frac{1yd^{2} }{9ft^{2} }

The ft^{2} unit cross cancels and your left with yd^{2}.

Now all you do is multiply straight across and you get \frac{729yd^{2} }{9}  = 81 yd^{2}

A phone sells for 245$ it is now on sale for 1/5 off the original price April has a coupon for a extra 10% off the sale price to
uranmaximum [27]

Answer:

$69

Step-by-step explanation:

A phone sells for $245 it is now on sale for 1/5 off the original price. Find the sale price:

\$245-\dfrac{1}{5}\cdot \$245=\$245-\$49=\$196

April has a coupon for a extra 10% off the sale price. Find how much will April pay using her discount coupon:

\$196-\$196\cdot 0.1=\$196-\$19.6=\$176.4

Therefore, April will pay

\$245-\$176.4=\$68.6\approx \$69

less.

If nm = 8x - 14 and jk = x squared + 1, find JK
marissa [1.9K]

A parallelogram in which adjacent sides are perpendicular to each other is called a rectangle. The length of Jk can be either 10 or 26.

<h3>What is a rectangle?</h3>

A parallelogram in which adjacent sides are perpendicular to each other is called a rectangle. A rectangle is always a parallelogram and a quadrilateral but the reverse statement may or may not be true.

Since in a rectangle the opposite sides are equal, therefore, the sides NM and JK will be equal.

JK = MN

8x - 14 = x² + 1

0 = x² - 8x + 15

x = 5, 3

Hence, the length of Jk can be either 10 or 26.

The complete questions are:

Quadrilateral JKMN is a rectangle, if NM= 8x - 14 and JK= x squared + 1, find JK.
