I got no clue how to do this bruvvvvvvvvv

find the unknown angle mesure

Answers

Answer: 1=65° and 5=43

Step-by-step explanation:

Question 1:

Angles on a straight line always add up to 180°.

So to find the angle of x on the first question you have to do 180-115=65°

You would have to use this method for questions 2, 3 and 4 as well.

Question 5:

Right angles always add up to 90° so to work out what x is you would have to do 90-47=43

You would have to use this method for questions 6, 7 and 8.

Jewel spun a spinner and recorded the results in the table. What is the experimental probability of the spinner landing on an even number?

Answers

Answer:

1/2 or 3/6 or 50%

Step-by-step explanation:

Half of the numbers are even.

Consider a student’s work in determining the solution set of x > 2(y – 1)^2 – 2.

Test point: (2.25, 1.25)

x > 2(y – 1)^2 – 2

2.25 > 2(1.25 – 1)^2 – 2

2.25 > 2(0.25)^2 – 2

2.25 > 2(0.0625) – 2

2.25 > 0.125 – 2

2.25 > –1.875

Conclusion: The point (2.25, 1.25) satisfies the given inequality.

Solution set:

Which element, if any, shows an error in the student’s work?

There are no errors.
The conclusion statement is incorrect.
The graph of the solution set is incorrect.
The substitution of x and y values is incorrect.

Answers

Answer:

C. The graph of the solution set is incorrect.

Step-by-step explanation:

Solution is right, properly substituted x- and y-values, no mistakes. Conclusion is right, the point within the solution set. The only mistake is the graph, with > sign the line of the graph is not included into solution, therefore should be dotted.

Answers

Answer:

$45,395.39

Step-by-step explanation:

The formula for an amount earning compound interest is ...

A = P(1 +r/n)^(nt)

where principal P is invested at annual rate r compounded n times per year for t years.

Using the given numbers, we have ...

A = $10,000(1 +0.038/4)^(4·40) ≈ $45,395.39

The charity will receive $45,395.39.

Frank weighs 160 pounds and is on a diet to gain 2 pounds a week so that he can make the football team. John weighs 208 pounds and is on a diet to lose 3 pounds a week so that he can be on the wrestling team in a lower weight class. If Frank and John can meet these goals with their diets, when will they weigh the same, and how much will they weigh at that time? (Hint: Solve for x and y and make sure you write a complete sentence for an answer)

Answers

Answer: If Frank and John can meet these goals with their diets , they will weigh same after 9.6 weeks and they will weigh 179.2 pounds.

Step-by-step explanation:

Let x = Number of weeks.

As per given question ,

Weight of Frank after x weeks = 160+2x (pounds)

Weight of John after x weeks = 208-3x (pounds)

When Weight of Frank= Weight of John

Weight of Frank after 9.6 weeks = 160+2(9.6) = 179.2 pounds

Weight of John after 9.6 weeks = 208-3(9.6)=179.2 pounds

Hence, If Frank and John can meet these goals with their diets , they will weigh same after 9.6 weeks and they will weigh 179.2 pounds.

Answers

Answer:

41.29 cm²

Step-by-step explanation:

From the question,

Area of the shaded portion = Area of the circle - area of the square.

A' = πr²-L²...… Equation 1

Where A' = Area of the shade portion, r = radius of the circle, L = length of the square, π = pie

Given: r = 4 cm, L = 3 cm

Constant: π = 22/7.

Substitute these values into equation 1

A' = [(22/7)×4²]-3²

A' = 50.29-9

A' = 41.29 cm²

Hence the area of the shaded portion is 41.29 cm²
