Solve is for solving the answer, and check is for checking your work. Is it alright if anybody could solve it before an hour?

Answers

Answer:

1. x = 6 check: 3 * 6 = 18

2. x = -12 check: -12/3 = -4

3. x = 11 check: 11 * 11 = 121

4. y = -4 check: -8 * -4 = 32

Step-by-step explanation:

1. x=6 ( 3×6=18)

2. x = -12 (-12÷3 = -4)

3. x=11 (11×11=121)

4 y=-4 (-8 × -4 = 32)

You are checking a bag at the airport. Your bag weighs 16 pounds plus 2 more pounds for each souvenir you add. How many souvenirs can you add if bags can weigh no more than 50 pounds?

Answers

Answer:

Step-by-step explanation:

50 - 16 = 34

34 / 2 = 17

34 + 17 = 51, which is too much; so we take 1 souvenir out which would be 16.

Quick check:

34 + 16 = 50

A company produces two types of jackets; windbreakers and rainbreakers. The company has at most 61 hours of finishing time per week and 67 hours of packaging time per week. Each windbreaker jacket takes 59 minutes of finishing time and 21 minutes of packaging time per week, whereas each rainbreaker jacket takes 58 minutes of finishing time and 34 minutes of packaging time per week. The company's profit for each windbreaker and rainbreaker jacket is 28 and 41, respectively. Let x denote the number of windbreaker jackets they should produce and y denote the number of rainbreaker jackets they should produce. The company wants to maximize profit. Set up the Linear Programming Problem for this situation.

Answers

Answer:

Max p = 28x + 41y

Subject to

59x + 58y ≤ 3660

21x + 34y ≤ 4020

x ≥ 0, y ≥ 0

Step-by-step explanation:

As given ,

Windbreakers Rain breakers Total

Finishing time 59 min 58 min 61 hr

Packaging time 21 min 34 min 68 hr

Profit 28 41

Let

The number of windbreaker jackets they should produce = x

The number of rain breaker jackets they should produce = y

As given,

The company wants to maximize profit.

⇒ Maximum Profit , p = 28x + 41 y

Now,

As 1 hour = 60 min

⇒61 hours = 61×60 = 3660 min

and 67 hours = 67×60 = 4020 min

∴ we get

The equations become

59x + 58y ≤ 3660

21x + 34y ≤ 4020

x ≥ 0, y ≥ 0

So, the Linear Programming Problem (LPP) for this problem is -

Max p = 28x + 41y

Subject to

59x + 58y ≤ 3660

21x + 34y ≤ 4020

x ≥ 0, y ≥ 0

Reflect (4,3) across the x-axis. Then reflect the result across the y-axis. What are the coordinates of the final point

Answers

Answer: (-4,-3)

Step-by-step explanation:

(4,3) quadrant 1

(-4,3)quadrant 2 wasn't used in this

(4,-3) quadrant 3

(-4,-3)Quadrant 4

just trust me and I don't know how this is

college homework lol but okay

Reflection involves mirroring a point over a line. When (4,3) is reflected across the x and y axes, the final point is (-4,-3)

Given that

[tex](x,y) = (4,3)[/tex]

The rule of reflection across the x-axis is:

[tex](x,y) \to (x,-y)[/tex]

So, we have:

[tex](4,3) \to (4,-3)[/tex]

The rule of reflection across the y-axis is:

[tex](x,y) \to (-x,y)[/tex]

So, we have:

[tex](4,-3) \to (-4,-3)[/tex]

Hence, the final point of (4,3) is (-4,-3)

Question -3+13x=9.

Explain the steps of how you would find the value of x.
What is the value of x?
How do you know that your answer is correct? How can you prove that?

Answers

Answer:

-3+13x=9.

13x=9+3

13x=12

x=12/13

i proved it by putting value of x in reactant side you get product .

-3+13×12/13=9

Answer:

x = 12/13

Step-by-step explanation:

-3 + 13x = 9

Adding 3 to both sides,

13x = 12

Dividing both sides by 13,

x = 12/13

We can prove it by putting the value of x we got in the given equation:

LHS = -3 + 13x

= -3 + 13 (12/13)

= -3 + 12

= 9 = RHS

Hence, proved.

A maintenance technician sights the top of a telephone pole at a 25° angle of elevation as shown. Technician Telephone Pole Determine the horizontal distance between the technician and the base of the telephone pole to the nearest tenth of a foot. Enter your answer in the box.

Answers

Answer:

[tex]x = 375.3[/tex]

Step-by-step explanation:

Given

See attachment for illustration

Required

Determine the horizontal distance

The horizontal distance is the distance between the technician and the base of the pole.

Represent this with x.

The relationship between x, 175ft and 25 degrees is represented as:

[tex]tan(25^{\circ}) = \frac{175}{x}[/tex] --- i.e. tan formula

Multiply both sides by x

[tex]x * tan(25^{\circ}) = \frac{175}{x} * x[/tex]

[tex]x * tan(25^{\circ}) = 175[/tex]

Make x the subject

[tex]x = \frac{175}{tan(25^{\circ})}[/tex]

[tex]x = \frac{175}{0.4663}[/tex]

[tex]x = 375.294874544[/tex]

[tex]x = 375.3[/tex] --- approximated

The distance is approximately 375.3ft

In a correlational study, ____.
A. one variable is measured and two groups are compared
B. two variables are measured and two groups are compared
C. one variable is measured and there is only one group of participants
D. two variables are measured and there is only one group of participants

Answers

Answer:

Option B, two variables are measured and two groups are compared

Step-by-step explanation:

In a correlation study relationship between two variable is established.

The two variables represents two group.

For instance correlation study is conducted to determine the relationship between two variables X and Y

X and Y are variable

While X represents the group "number of cars passing through a lane"

Y represents the group "width of the road".

Hence, Option B is correct

10. Carl wants to buy a television that costs $400,
including taxes. To pay for the television, he will use
a payment plan that requires him to make a down
payment of $150, and then pay $70.50 each month
for 6 months. What is the percent increase from the
original cost of the television to the cost of the
television using the payment plan?

Answers

Calculate the total he will pay:

70.50 x 6 months = 423

423 + 150 = 573

He pays a total of 573

Find the difference from what he pays to what the actual price was:

573 - 400 = 173

Divide the difference by the actual price:

173 / 400 = 0.4325

Multiply by 100:

0.4325 x 100 = 43.25% increase

Suppose you know that ∠S and ∠Y are complementary, and that m∠S = 2(m∠Y) − 75°. Find m∠Y.

Answers

m∠s + m∠y = 90

m∠s = 90 - m∠y

m∠s= 2(m∠y) - 75

90 - m∠y = 2 m∠y -75

90 + 75 = 3 (m∠y)

165 = 3 (m∠y)

Suppose a game uses a spinner that has four possible outcomes: 1, 2, 3, and 4. What outcomes make up the complementary event of getting "2 or greater" on this spinner?

Answers

Answer:

Outcome of complementary event of getting "2 or greater" on the spinner = {1}

Step-by-step explanation:

Let A be an event of getting '' 2 or greater ''

The complementary event of A be = A' = getting ''less than 2 ''

Now,

The Sample space S = { 1, 2, 3, 4 }

Outcome of A' = { 1 }

∴ we get

Outcome of complementary event of getting "2 or greater" on the spinner = {1}
