Not sure if you mean “Round 37 to the nearest tenth” but if so then it’s “40”.
Answer:
A
Step-by-step explanation:
The measurements of the segments fall on similar triangles. This means the lengths of each segment can be found using proportions.
Remember, a proportion is an equation which sets equal ratios equal to each other.
To solve for c, multiply numerators and denominators across the equal sign:
24c = 32(15)
24c = 480
c = 20
Answer:
The answer to your question is: 35 questions worth 2 points and 15 questions worth 3 points.
Step-by-step explanation:
Data
Number of questions = 50
Total points = 115
x = questions worth 2 points
y = questions worth 3 points
Process
write to equations
(1) --------------- x + y = 50
(2) -------------- 2x + 3y = 115
Solve them by substitution
x = 50 - y
2 (50 - y) + 3y = 115
100 - 2y + 3y = 115
3y -2 y = 115 - 100
y = 15
x = 50 - 15
x = 35
10) 4 1/2 inches thick. You would add them together and simplify 2/4 into 1/2.
11) Yes. He needed a stick that was about 5 feet long. It is only a little longer and he could easily make it shorter.
Answer:
1
Step-by-step explanation:
Probability is given by number of possible outcomes ÷ number of total outcomes
Assuming we stop rolling the six-sided die once our sum is 290 ( exceeds 285)
Number of possible outcomes = 75, number of total outcomes = 290
Probability (75 rolls are needed to get this sum) = 75/290 = 0.259
Probability (more than 75 rolls are needed to get this sum) = 1 - 0.259 = 0.741
Probability (at least 75 rolls are needed to get this sum) means that either 75 rolls or more than 75 rolls are needed to get this sum = 0.259 + 0.741 = 1
