Answer:
34 cm
Step-by-step explanation:
Keep in mind that the perimeter of a rectangle is the sum of the measures of its sides. This means that the sum of the longer sides and the shorter sides is the perimeter of the rectangle.
Let "L" represent the longer side (length) of the rectangle and "S" represent the shorter side (width) of the rectangle.
⇒ Perimeter of rectangle = L + S + L + S
⇒ Perimeter of rectangle = 2(L) + 2(S)
⇒ Perimeter of rectangle = 2(L + S)
Now, let's substitute the length and the width in the perimeter and simplify.
⇒ Perimeter of rectangle = 2(10 + 7) [L = 10; S = 7]
⇒ Perimeter of rectangle = 2(17)
⇒ Perimeter of rectangle = 34 cm
Answer: 20 questions
Step-by-step explanation:
From the question, Noah is taking an online survey and after answering 16 questions, he gets a message that he has completed 80% of the survey.
To get the total number of questions in the survey goes thus:
Let the total number of questions be y.
80% of y = 16
80/100 × y = 16
0.8 × y = 16
0.8y = 16
Divide both side by 0.8
y = 16/0.8
y = 20
The survey has 20 questions.

Answer:
- f(0) ≈ 22
- f(1) = 10
- f(b) ≈ -8
- f(c) = 0
- f(d) 24
Step-by-step explanation:
This takes graph-reading one step further. You get to estimate the y-value without benefit of minor grid lines. You must mentally divide the 10-unit distance between grid lines into equal spaces. Then estimate how many of those spaces lie between the point and the nearest grid line.
You can do this more precisely by drawing a diagonal line across the grid from one major grid intersection to one that is (5, 1) or (5, -1) major grid points away. Where that line crosses the intermediate grid lines, the vertical measure will be some multiple of 1/5 of the vertical difference between grid points. For example, a line from (0,20) to (5,30) will cross at (1,22), (2,24), (3,26), and (4,28). You can use these reference points to identify the y-values at f(0) and f(d).
Here's our eyeball estimate:
- f(0) ≈ 22
- f(1) = 10
- f(b) ≈ -8
- f(c) = 0
- f(d) 24
