Answer:

x = 33

Step-by-step explanation:

Sum of the interior angles of a 5-sided polygon = 540°

Therefore all the interior angles of the given polygon would all be equal to 540°.

Thus:

(4x - 25)° + (3x + 25)° + (2x - 3)° + (4x)° + (3x + 15)° = 540°

Solve for x

4x - 25 + 3x + 25 + 2x - 3 + 4x + 3x + 15 = 540

Combine like terms

4x + 3x + 2x + 4x + 3x - 25 + 25 - 3 + 15 = 540

16x + 12 = 540

16x = 540 - 12

16x = 528

Divide both sides by 16

x = 33

Answer:

69°

Step-by-step explanation:

180 - 21 -90 = 69

hope this helps...

Answer: The missing angle is 69°

Step-by-step explanation: When all the angles have their vertex on a straight line, they must add up to 180° They are "supplementary" angles.

The "box" in the corner of an angle is a symbol for "right angle" so that is a way to have a "given" 90°

Knowing that, you can add the "given" 90° + 21° to get 111°

Subtract 111° from 180° to find Angle a:

180 - 111 = 69

The price to mail a letter at the post office is $0.35 for the first ounce and $0.17 for each additional ounce. Amrit paid $2.05 to mail his letter. How much did the letter weigh?

Answers

As we know the first ounce cost $0.35, we can subtract that from $2.05.

Therefore, $2.05 - $0.35 = $1.70

We can then divide the remaining amount of money by $0.17 to find out how many more ounces the letter weighed.

$1.70/$0.17 = 10

Once we add the ounce before that costed $0.35 to the 10 ounces that we just calculated, we know that Amrit’s letter cost 11 ounces.

A new cell tower is being constructed and needs a guy-wire connected 180 feet up the tower and it needs to make an angle of 52° with the ground. What length does the wire need to be?

Answers

Answer:

228.42 ft

Step-by-step explanation:

To solve for this question, we would be applying the Trigonometric function of Sine.

Sin theta = Opposite/Hypotenuse

Theta = 52°

Opposite = 180ft

Hypotenuse = Length of the wire = x

Hence:

sin 52 = 180/x

x = 180/sin 52

x = 228.42327871 ft

Approximately = 228.42 ft

Which costs the most per ounce, 60 oz. of peanut butter for $5.40, 28 oz. for $2.24, or 16 oz. for $1.76? Explain how you got your answer.

Answers

Answer:

28 oz. for $2.24 cost most per ounce

$12.5 per oz

Step-by-step explanation:

Find the cost per ounce by dividing the total oz by cost of the total oz

60 oz. of peanut butter for $5.40

Cost per the ounce = 60 oz / $5.40

= $11.11 per oz

28 oz. for $2.24

Cost of peanut butter per ounce = 28 oz / $2.24

= $12.5 per oz

16 oz. for $1.76?

Cost of peanut butter per ounce = 16 oz / $1.76

= $9.10 per oz

28 oz. for $2.24 cost most per ounce

A lawyer has an annual income of $154,120. The income tax the lawyer has to pay is 6%. What is the amount of income tax in dollars and cents that the lawyer has to pay

Answers

Answer:

$9,247.20

924,720 cents

Step-by-step explanation:

The computation of the amount of the income tax is shown below:

In dollars

= Annual income × rate of income tax

= $154,120 × 6%

= $9,247.20

Now in cents, it would be

= Annual income × rate of income tax × 100

= $154,120 × 6% × 100

= 924,720 cents

Solve the proportional
equation below:
10/4=x+8/x-1
PLS HELP AND EXPLAIN HOW U GOT THE ANSWER

Answers

Answer:

x = 7

Step-by-step explanation:

10 / 4 = x + 8 / x - 1

[cross multiply]

10 (x - 1) = 4 (x + 8)

[distribute the factors]

10x - 10 = 4x + 32

+ 10 + 10

[add 10 to both sides to cancel out -10]

10x = 4x + 42

-4x -4x

[subtract both sides by 4x to cancel out 4x]

6x = 42

÷6 ÷6

[divide both sides by 6 to simplify 6x to x]

x = 7

________

x = 7 → 10 / 4 = x + 8 / x - 1 →

(7) + 8 / (7) - 1 → 15 / 6 →

15 ÷ 3 / 6 ÷ 3 → 5 / 2 →

5 × 2 / 2 × 2 → 10 / 4 = 10 / 4

Y=x. Given A(7,-4), B(6,4), and C(-1,-5), what are the coordinates of the vertices of A’B’C for the reflection

Answers

Answer:

The coordinates of the vertices of A'B'C' is:

A'(-4, 7)B'(4, 6)C'(-5, -1)

Step-by-step explanation:

Given the coordinates of the triangle

A(7,-4)B(6,4)C(-1,-5)

Reflection in the line y=x

We know that the rule of reflection in the line is y = x is:

(x, y) → (y, x)

Thus,

The coordinates of the vertices of A'B'C' for the reflection in the y = x

(x, y) → (y, x)

A(7, -4) → A'(-4, 7)

B(6, 4) → B'(4, 6)

C(-1, -5) → C'(-5, -1)

Thus, the coordinates of the vertices of A'B'C' is:

A'(-4, 7)B'(4, 6)C'(-5, -1)

Answer:

Option D The pattern is multiplicative because the earnings are 12 times the number of hours worked in each pair of values is correct option.

Step-by-step explanation:

At x-axis we have number of hours worked and y-axis represents earnings in dollars.

We can make the table:

Number of hours worked (x) earnings in dollars (y)

1 12

2 24

3 36

4 48

5 60

Now, we need to find the pattern.

If we add 1+ 11 we get 12, but if we add 2+ 11 we get 13 and not 24 so, the pattern is not additive.

Now, if we multiply 1 by 12 (1 x 12) we get 12,

then 2 x 12 = 24

3 x 12 = 36

4 x 12 = 48

and 5 x 12 = 60

The same number if multiplied with x-axis we get y-axis.

So, the pattern is multiplicative. and we are multiplying 12 with the number of hours worked, so the correct option is option D.

Option D The pattern is multiplicative because the earnings are 12 times the number of hours worked in each pair of values is correct option.

Angel and Jayden were at track practice. The track is 2/5 kilometers around.  Angel ran 1 lap in 2 minutes.  Jayden ran 3 laps in 5 minutes. How far does Jayden run in one minute?

Answers

Answer:

6/25 km in 1 min; or 0.24 km/min

Step-by-step explanation:

The info about Angel is not necessary.

Jayden runs 3 laps in 5 mins

Each lap is 2/5 km, so Jayden runs 3 x (2/5 km) in 5 min = 6/5 km in 5 min.

Distance = rate x time

6/5 km = rate (5 min)

We want to isolate r (rate), so divide both sides by 5 min

6/5 km ÷ 5 min = r

6/5 km (1/5 min) = r

6/25 km/min = r (notice how the units worked out correctly to km/min)

So, Jayden runs 6/25 km in 1 min.

Answer:

6/25 miles km in a minute
