Answer:

The length of the building in the drawing  =  37 centimeter

Step-by-step explanation:

Here, the given scale is 1 centimeter : 3 meters

Now, the actual length of the given building is 111 meters.

Let us assume the length of the building in the drawing  =  k centimeter

So, according to the question:

k centimeters = 111 meters

Now, 1 cm  = 3 m

\implies 1 m = (\frac{1}{3})  cm\\\implies 111 m = 111 \times (\frac{1}{3})  cm  = 37 cm

or, k = 37 cm

or, 37 cm  =  111 meters

Hence, the length of the building in the drawing  =  37 centimeter

What is the gcf In this problem
scoray [572]
Find the GCF of 88 and 24 first 

88=2*2*2*11 
24=2*2*2*3 

The GCF for 88 and 24 is 8 
The GCF for r^18 and r^13 is r^13 (because they both contain r^13 in them) 

=8r^13(11, 3)

Find the coordinates of a point on a circle with radius 18 corresponding to an angle of 190°
devlian [24]

The coordinates of a point on a circle with radius 18 corresponding to an angle of 190° are (-17.73, -3.13).

What is transforming coordinates?

Polar coordinates (r,θ) are transformed into Cartesian coordinates (x, y) using the formulas x = r cos(θ), and y = r sin(θ).

This problem is under the concept of transforming polar coordinates (r,θ) to cartesian coordinates  (x, y).

For this problem the polar coordinates  are r = 18 and θ = 190°.

Convert these polar coordinates into a cartesian coordinates as,

x = r cos(θ) = 18 cos(190°) = -17.73

y = r sin(θ) = 18 sin(190°) = -3.13

The coordinates of a point on a circle with radius 18 corresponding to an angle of 190° are (-17.73, -3.13).

How many complete rotations will the bowling ball make if it rolls straight down the center of the entire length of the lane. A.
jasenka [17]
<h3>Answer: C) 26 complete rotations</h3>

===========================================

Explanation:

The diameter of the ball is 8.5 inches. So d = 8.5

The circumference of the circle with this diameter is

C = pi*d

C = pi*8.5

C = 8.5pi

C = 26.7035375555132 approximately.

This is the rough distance it travels in one revolution or one full rotation.

--------------

1 revolution = 26.7035375555132 inches

(1/26.7035375555132) revolution = 1 inch

1 inch = (1/26.7035375555132) revolution

1 inch = 0.03744822190398 revolution

There are 12 inches a foot, so,

1 inch = 0.03744822190398 revolution

12*1 inch = revolution

12 inches = 0.44937866284776 revolution

1 foot = 0.44937866284776 revolution

Now multiply both sides by 60

1 foot = 0.44937866284776 revolution

60*1 foot = 60*0.44937866284776 revolution

60 feet = 26.9627197708657 revolutions

Round down to the nearest whole number to get 26

We can't round to 27 even though we're really close to it. This is because we are looking for the number of whole revolutions the ball makes.

Therefore, 60 linear feet correspond to 26 full rotations of the ball. There's a bit leftover, but it's not enough to make another full rotation.

6x &lt; -96 <br> solve for x
olchik [2.2K]

Answer: Anything greater then -16 (EX: -15, -14)

Work: This is a One-Step Inequality equation, meaning you just need to divide. You need to get x by itself, so you divide the 6 on both sides, but since there is a negative, you have to flip the sign. So, the answer is x > -16.

Check: 6(-15) > -96;   -90 > -96 < It's correct.
