Find each measure m<1, m<2, m<3

Mathematics
1 answer:
Tom [10]3 years ago
4 0

Answer:

option 2.

m1 = 147°   m2 = 80°   m3 = 148°

Step-by-step explanation:

a flat angle has 180 °

m1 + 33 = 180

m1 = 180 - 33

m1 = 147

47 + 33 + x = 180

x = 180 - 47 - 33

x = 100

as they are two crossed lines the angle is reflected from the opposite side

48 + 100 + y = 180

y = 180 -100 - 48

y = 32°

180 = m3 + 32

m3 = 180 - 32

m3 = 148

With the same principle as the previous one we know that the angle of a turn is 360 °, if we subtract the 2 known angles and divide it by 2 we will obtain the missing angle

m2 * 2 = 360 - 100*2

m2 = 160 / 2

m2 = 80

F(x) = [[x]], what is f(9)?
Inga [223]

Okay so in this expression, the variable x is set to 9.

Because this expression is just x = x, whatever the value of x is will be the same for both x's.

So, f(9) = 9

Can you help me with the problem listed in the pictures below? Please and thank you. Will mark BRAINLIEST!!! :)
vagabundo [1.1K]

Answer:

14 books

Step-by-step explanation:

Let b = number of books at the beginning

She sold 1/2 of the books

b - 1/2 b

This is how many she had left

Then she bought 7

b - 1/2 b + 7

this equals 14

b - 1/2 b + 7 = 14

Combine like terms

1/2 b + 7 = 14

Subtract 7 from each side

1/2 b = 14-7

1/2 b = 7

Multiply each side by 2

1/2 b * 2 = 7*2

b = 14

She started with 14 books

Q1. Ten percent of the items produced by a machine are defective. A random sample of 100 items is selected and checked for defec
Tcecarenko [31]

Answer: 0.030

Step-by-step explanation:

Given: The percent of the items produced by a machine are defective  :P=10\%=0.10

The percent of the items produced by machine which are not defective:Q=1-0.1=0.9

Sample size : n = 100

Now, the standard error of the proportion is given by :-

\text{S.E.}=\sqrt{\dfrac{0.1\times0.9}{100}}\\\\\Rightarrow\text{S.E.}=0.030

Hence, the the standard error of the distribution of the sample proportions=0.030

A restaurant customer left a $3.50 as a tip. The tax on the meal was 7% and the tip was 20% of the cost including tax. (Complete
Maru [420]

Answer: 17.50

Step-by-step explanation:

20% of x = 3.50

(20/100) x = 3.50  Divide top and bottom of the left number by 20

(20÷20) / (100÷20)  *  x = 3.50

(1/5) x = 3.50           Multiply both sides by 5  

x = 3.50 * 5

x = 17.50

The meal cost 17.50
