Answer 1

Answer:

The measure of ∠A = 58.0°

Step-by-step explanation:

we will use the trigonometry function "tan" to solve the question

∵ BC is the opposite side of ∠A

∵ AC is the adjacent side of ∠A

∵ tan A = [tex]\frac{opposite}{adjacent}[/tex]

∴ tan A = [tex]\frac{BC}{AC}[/tex]

BC = 8 units

AC = 5 units

∴ tan A = [tex]\frac{8}{5}[/tex]

→ Use the inverse function of tan to find the measure of angle A

∵ m∠A = [tex]tan^{-1}(\frac{8}{5})[/tex]

∴ m∠A = 57.99461679°

→ Round it to the nearest tenth

∴ m∠A = 58.0°

The measure of ∠A = 58.0°

Which two statements describe how saving $200 every month in her traditional 401(k) retirement account is different from saving $200 every month for her car? Select all the correct answers. Isabel’s retirement savings are made with after-tax dollars. Isabel’s retirement savings are made with pretax dollars. Isabel’s retirement savings can be used for other purposes without penalty. Isabel’s retirement savings have more liquidity than the money in her savings account. Isabel’s retirement savings have no contribution limits. Isabel’s retirement savings may include a contribution from her employer.

Answers

Answer:

Isabel’s retirement savings are made with pretax dollars.

Isabel’s retirement savings may include a contribution from her employer.

Step-by-step explanation:

When you contribute to an IRA account, your contribution is tax deductible. This means that all the money that you contribute to your account comes from pretax dollars. This contribution is limited to $19,500 per year (for 2020) or $26,000 if you are 50 or older.

Your employer can also contribute to your 401(k) account and employer's contribution may be even higher than the employee's. Total contributions including employer's and employee's cannot exceed $57,000 per year (or $63,500 if 50 or older) or the employee's total compensation per year, whichever is lower.

A game room has a perimeter of 70 ft. The length is 5 more than twice the width. How many feet squared of new carpeting should be ordered?

Answers

Answer:

A = 250 square ft

Step-by-step explanation:

Equations

Let's call:

x = width of the game room

The length is 5 more than twice the width, thus:

2x+5 = length of the game room

The perimeter of a rectangle is twice the sum of the width and the length:

P = 2( x + 2x + 5 )

And the perimeter is 70 ft:

2( x + 2x + 5 ) = 70

Operating:

2( 3x + 5 ) = 70

Dividing by 2:

3x + 5 = 35

Subtracting 5:

3x = 30

Dividing by 3:

x = 30 / 3

x = 10

The width is 10 ft and the length is 2(10)+5=25 ft

The area of the game room is:

A = 10 ft * 25 ft

A = 250 square ft

Name all the angles that have V as a vertex.

Answers

Answer:

Angle 3

Angle 4

Angle DVE

Angle FVE

Angle DVF

The angles that have V as a vertex are:

[tex]\angle 3 \\\\\angle 4\\\\\angle DVF\\\\\angle DVE\\\\\angle EVF[/tex]

Recall:

A vertex of any angle is simply the corner of an angle that forms a V-shape.

Three points make up an angle

Letters can be used to represent the three points

The letter at the middle of the three letters is the vertex of the angle

Angles can be named using the numbers that are used in labelling the vertex of each angle

Thus, from the given image,

Each of the following angles has V as the vertex of its angle:

[tex]\angle 3 $ and $ \angle 4[/tex] has vertex V

[tex]\angle DVF, $ \angle DVE, $ and \angle EVF[/tex] has V as a vertex.

Therefore, the list of all angles having V as a vertex are:

[tex]\angle 3 \\\\\angle 4\\\\\angle DVF\\\\\angle DVE\\\\\angle EVF[/tex]

Chose the missing side length and the trigonometric ratio you would use to calculate.

Answers

Answer:

The missing value is 2.9mm and cosine was used

Step-by-step explanation:

Given triangle is a right-angled triangle  we can use trigonometric ratios to calculate the missing length.

In the given triangle,

Base = k

Hypotenuse = 15mm

Angle = 79

We will use trigonometric ratio which includes base and hypotenuse.

Using cosine,

[tex]cos\ (angle) = \frac{Base}{hypotenuse}\\cos\ 79 = \frac{k}{15}\\k = cos\ 79 * 15\\k = 0.1908*15\\k = 2.862[/tex]

Rounding off to nearest tenth

[tex]k= 2.9mm[/tex]

Hence,

The missing value is 2.9mm and cosine was used

A juice factory offers its juice in both bottles and cans. A class of students on a field trip decides to compare the numbers on cases of bottled juice and canned juice that are packaged each minute. The students count the number of cases that are packaged on each assembly line over several minutes.

Answers

The unit rate for canned juice, in cases per minute is; 50 cases per minute is; cases per minute

How to find the unit rate?

From the attached file, we see that it is a graph showing canned juice on the y-axis and time taken in minutes on the x-axis.

Now, to find the unit rate also means to find the slope from 2 defined points. From the given graph, we will take the coordinates;

(1, 50) and (2, 100)

Thus;

Slope = (100 - 50)/(2 - 1)

Slope = 50 cases per minute

Thus, the unit rate for canned juice, in cases per minute is; 50 cases per minute.

3. A $5,000 principal is invested in two accounts, one earning 1% interest and another earning 6%
interest. If the total interest for the year is $170, then how much is invested in each account?

Answers

Let, amount invested in first account is x.

So, amount invested in second account is ( 5000 - x ).

Now,

Total interest = Interest from 1  + Interest from 2

170 = x × 0.01 × 1 + ( 5000 - x ) × 0.06 × 1

17000 = x + 6( 5000 - x )

17000 = x + 30000 - 6x

5x = 30000 - 17000

x = $2600

Therefore, money invested in first and second account is $2600 and $2400.

Hence, this is the required solution.

Noel works as a driver for a transportation company. On average, he drives 152 hours to make 19 successful deliveries. Assume this rate is his constant rate for delivering goods. If you graph this relationship with time along the x-axis and number of deliveries along the y-axis, the slope of the line you get gives Noel's unit rate for a successful delivery. Which unit rate can be interpreted as the slope?

a: 8 deliveries per hour
b :2/17 of an hour per delivery
c: 1/8 of a delivery per hour
d: 1/8 of an hour per delivery

Answers

Answer:

A

Step-by-step explanation:

By doing the unit rate, dividing 19 on both the top and bottom, getting this 8.36.../1, you can just round it to 8/1, meaning he makes about 8 deliveries per hour. Hope this helps!
