Diameter = 22 mm
Radius = diameter/2 = 22/2 = 11 mm
Area = pi r^2
Area = pi (11^2) = 380.133 mm^2

No option corresponds to the answer 380.133

If we round off 380.133 and 379.94 it then becomes 380. So answer D.

Any locker with a number that is a multiple of 8, 12, and 75 will contain all three animals.

The least common multiple of these three numbers is

\mathrm{lcm}(8,12,75)=600

and so any multiples of 600 between 1 and 3500 will contain all three animals. These are 600, 1200, 1800, 2400, and 3000.

Why is the LCM 600? You can determine that using the prime factorizations of the three given numbers:

8=2^3
12=2^2\times3
75=3\times5^2

The LCM can be obtained by multiplying as many prime numbers together as are needed to contain the prime factorizations of the three numbers. This is obtained with

2^3\times3\times5^2=8\times3\times25=600

(at least three 2s to get the 8; at least one 3 and two of the previous 2s to get 12; and at least two 5s along with the previous 3 to get 75)

6. What is the sum of the solutions?
vlada-n [284]

x * x = x^2

x * .7 = .7x

-6 * x = -6x

-6 * .7 = -4.2

x^2 + .7x - 6x -4.2

x^2 - 5.3 - 4.2

x = 6

We add the scale factor to each length of an image to get the scaled copy.<br> -True or False?
Anit [1.1K]

Answer:

false

Step-by-step explanation:

A scale drawing is a reduced form in terms of dimensions of an original image / building / object

the scale drawing is usually reduced at a constant dimension

original dimensions / scale of the drawing  = dimensions of the scale drawing

To scale an image, divide the original length by the scale

for example the length of the image is 100 and the scale factor is 4

the length of the scale copy = 100/4 = 25
