Range is given by:
(maximum value)-(minimum value)
The range of calories from morning snack will be given as follows:
maximum value=225
minimum value=85
range=225-85=160
The range of calories from the evening snack will be:
maximum value=465
minimum value=225
range=450-225=240
The difference in range
240-160=80
Hence the conclusion will be:
The range of calories in George's morning snack is about 80 less
<span>the range of calories in his after noon snack.</span>
Answer:
C. 139 ft
Step-by-step explanation:
Height of the pole = x + 4 ft
First, find x using trigonometric function.
Reference angle = 44°
Opposite side length = x
Adjacent side length = 140 ft
Apply TOA, which is:
Tan 44 = opp/adj
Tan 44 = x/140
Multiply both sides by 140
140 × Tan 44 = x
135.196428 = x
x ≈ 135 ft
✔️Height of the pole = x + 4 ft = 135 + 4 = 139 ft
Answer:
12 units³
Step-by-step explanation:
original volume of box = 120 units³
If the box if it is scaled down by a factor of 1/10, then we multiply the original volume by 1/10:
120 x (1/10) = 120 ÷ 10 = 12 units³
Answer:
Step-by-step explanation:
Total number of questions in the test is 20.
Total number of questions that Alyssa answered correctly is 16.
The percentage of questions that she answered correctly would be
16/20 × 100 = 80%
To get an A, she needs to answer 90% of the questions correctly. Let x represent the number of questions that she needs to answer correctly to get an A. Therefore,
x/20 × 100 = 90
100x = 20 × 90 = 1800
x = 1800/100 = 18
She would need to answer 18 questions correctly to get an A
Alyssa's friend Jessie answered three times more questions correct than incorrect. This means that for every 3 correct answers, she had 1 wrong answer. For 15 correct answers ,she would get 5 wrong answers. Therefore, she got fewer correct answers than Alyssa.
Her percentage is
15/20 × 100 = 75%
Alyssa got a higher percentage of the test questions correct.
