Answers
Answer:
The correct answer is A. Sin A= 3/5 cos A = 4/5
Let me see.
sin A =opposite/hypotenuse
cos A = adjacent/hypotenuse
Look at the diagram.
Clearly, opposite angle A we have 3.
The hypotenuse is 5.
So, we conclude that sin A = 3/5.
Go back to the diagram.
The height of the triangle is the adjacent side to angle A for this problem.
Think about it this way:
The adjacent side is the height 4.
The hypotenuse we know as 5.
So, cos A = 4/5.
The answer is choice A

The diagram shows a playground in the shape of a trapezium.
50 m
U
32m
90 m
Work out the area of the playground.
Answers
Answer:
[tex] 2240 {m}^{2} [/tex]Step-by-step explanation:
Given,
Parallel sides of the trapezium = 50m, 90m
Height of the trapezium = 32m
Therefore,
Area of the trapezium
[tex] = \frac{1}{2} \times sum \: of \: parallel \: sides \: \times \: height[/tex]
[tex] = \frac{1}{2} \times (50 + 90)m \times 32m[/tex]
= (50 + 90) m × 16m
= 140m × 16m
[tex] = 2240 {m}^{2} (ans)[/tex]
Answer:
A = 2240 m²
Step-by-step explanation:
The area (A) of a trapezium is calculated as
A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )
where h is the perpendicular height and b₁, b₂ the parallel bases
Here h = 32 , b₁ = 90 and b₂ = 50 , then
A = [tex]\frac{1}{2}[/tex] × 32 × (90 + 50) = 16 × 140 = 2240 m²
If you have $4.00, how many pounds of apples can you buy?
A. 7 pounds
B. 7/4 of a pound
C. 4/7 of a pound
D. 2 2/7 pounds
Answers
Answer:
[tex]2 \frac{2}{7}[/tex] pounds, D
Step-by-step explanation:
1 pound of apples = 1.75 dollars.
Set the number of pounds of apples as x.
Then, we can write this equation.
1.75x = 4
[tex]\frac{7}{4}[/tex]x = 4
Divide both sides by [tex]\frac{7}{4}[/tex]
x = [tex]\frac{4}{1}[/tex] * [tex]\frac{4}{7}[/tex]
x = [tex]\frac{16}{7}[/tex]
x = [tex]2 \frac{2}{7}[/tex]
Thus, the answer is D, x = [tex]2 \frac{2}{7}[/tex] pounds

Based on these results, express the probability that a seventh grader chosen at
random will play the drums as a decimal to the nearest hundredth.
Answers
Answer:12/77
Step-by-step explanation:
The probability that a seventh grader chosen at random will play an instrument other than the Guitar is 0.76.
What is probability?Its fundamental concept is that someone will nearly surely occur. The proportion of positive events in comparison to the total of occurrences. Then the probability is given as,
P = (Favorable event) / (Total event)
The total event for seventh grade is given as,
Total = 9 + 9 + 11 + 9
Total = 38
The probability that a seventh grader chosen at random will play an instrument other than the Guitar is calculated as,
P = 9/38 + 11/38 + 9/38
P = 29/38
P = 0.76

How many solutions does the equation 5x+17=4(3x−1) have?
Answers
Answer:
one solution = 3
Step-by-step explanation:
Let's solve your equation step-by-step.
5x+17=4(3x−1)
Step 1: Simplify both sides of the equation.
5x+17=4(3x−1)
5x+17=(4)(3x)+(4)(−1)(Distribute)
5x+17=12x+−4
5x+17=12x−4
Step 2: Subtract 12x from both sides.
5x+17−12x=12x−4−12x
−7x+17=−4
Step 3: Subtract 17 from both sides.
−7x+17−17=−4−17
−7x=−21
Step 4: Divide both sides by -7
-7x/-7 = -21/-7 = 3

Shalini’s vNM utility for money is u(x) = x1/2, where x is her final wealth level. She currently has $1600 and is uninsured. When she drives her car she faces the following gamble. With 90% probability she will not get into an accident, and with 10% probability she will get into an accident and incur $1500 in auto damages. What is the maximum amount she would be willing to pay for an insurance policy that completely covers any auto damages?
Answers
Answer:
Shalini
The maximum amount that she would be willing to pay for an insurance policy that completely covers any auto damages is:
= $150.
Step-by-step explanation:
Utility for money, u(x) = x1/2
x, her final wealth level = $1,600
Loss from accident
Probability Loss incurred Expected Loss
90% $0 $0 (90% * $0)
10% $1,500 $150 (10% * $1,500)
100% $150
b) The amount that Shalini would be willing to pay for an insurance policy for all auto damages is limited to her expected loss from auto damages. Since she has a 90% chance of not being involved in an accident, her expected loss will be reduced to $150. This represents 10% of the loss from damages that she would incur if she was involved in an accident, which is 10% probable.
