Since the binoculars make things 10 times larger, you need to multiply 0.43 inches by 10.
0.43 inches * 10 = 4.3 inches
Answer: D. 5 > x > 1
1 < 3x -2 < 13
<=> 3 < 3x < 15
<=> 1< x < 5
Step-by-step explanation:

Step-by-step explanation:
A suitable calculator can give you the answer to this right away. Or, you can try the answer choices in the equations to see which works.
The answer choice that works is choice B.
2·1 +3 -(-2) = 7
-1 -2(3) +4(-2) = -15
1 +2(3) -5(-2) = 17
Answer:
-x
Step-by-step explanation:
(x + 3)(x – 4) = x^2 - 4x + 3x - 12 = x^2 - x - 12
The middle term is -x.
Answer:
a). 18
b). 26%
c). 39
Step-by-step explanation:
Given question is incomplete; here is the complete question attached.
a). In this part we have to calculate the number of the people surveyed who make less than 5 calls.
From the given table,
Number of people surveyed who make less than 5 calls Or 1 - 4 calls = 18
b). Total number of people surveyed = 18 + 11 + 5 + 3 + 2 = 39
Number of people surveyed, make at least 9 calls = 5 + 3 + 2 = 10
Percentage of these people = ![\frac{\text{People who make calls more than 9 calls per day}}{\text{Total number of people surveyed}}\times 100](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctext%7BPeople%20who%20make%20calls%20more%20than%209%20calls%20per%20day%7D%7D%7B%5Ctext%7BTotal%20number%20of%20people%20surveyed%7D%7D%5Ctimes%20100)
= ![\frac{10}{39}\times 100](https://tex.z-dn.net/?f=%5Cfrac%7B10%7D%7B39%7D%5Ctimes%20100)
= 25.64%
≈ 26%
c). Total number of people surveyed = 18 + 11 + 5 + 3 + 2 = 39
