Mathematics
1 answer:
aleksley [76]3 years ago

Answer:

132

Step-by-step explanation:

so all the angles of a triangles add up to equal 180 so to find the missing angle of the triangles we do 180-86-46 which equals 48. x is supplementary to the angles that equals 48 meaning that they will add up to equal 180. 180-48 = 132 so x =132

Four of a sample of 150 computers will be selected and tested. How many different ways are there to make this selection?
klio [65]
The formula C(n, r) calculates the total number of ways of picking r objects out of n.

The formula works as follows:

C(n, r)= \frac{n!}{r!(n-r)!}

where n! is 1*2*3*...*(n-1)*n

So, we calculate C(150, 4), which will give us the total number of ways we can make the selection of the computers.

C(150, 4)= \frac{150!}{4!(150-4)!}=\frac{150!}{4!146!}= \frac{150*149*148*147*146!}{4!*146!}= \frac{150*149*148*147}{4!}

= \frac{150*149*148*147}{4*3*2*1}= 20,260,275 many ways.

Answer: 20,260,275

The mass of the Eiffel Tower is about 9.16 ⋅ 106 kilograms. The mass of the Golden Gate Bridge is 8.05 ⋅ 108 kilograms. Approxim
Pavel [41]
9.16 times 106=970.96
8.05 times 108=869.4
Next, subtract 970.96 minus 869.4.  That equals 101.56.
Then, to put that in scientific notation move the decimal three places to the left.  The answer is 1.0156x10^2
