.A 15 m ladder rests against a wall at an angle of 60° with the ground. How far is the
foot of the ladde from the wall?

Answers

Answer 1

9514 1404 393

Answer:

  7.5 m

Step-by-step explanation:

The cosine relation applies.

  Cos = Adjacent/Hypotenuse

  cos(60°) = (distance to wall)/(15 m)

  distance to wall = (15 m)cos(60°) = (15 m)(1/2) = 7.5 m

The foot of the ladder is 7.5 m from the wall.

5 Clear 1 Petrov ran 7 laps around a track. Each lap around the track is a distance of mile. What is the total distance Petrov ran in feet? A 9,240 ft 3,017 ft 1,327 ft 36,960 ft​

Answers

Answer: 36,960 ft

Step-by-step explanation:

Each lap around the track was a mile in distance.

Petrov therefore ran a total of 7 miles.

A mile is 5,280 feet.

If Petrov ran 7 miles in total, this distance in feet is:

= 7 * 5,280

= 36,960 ft

Breyelle is planning on purchasing a new sports-utility vehicle. The list price of the one she is most interested in buying is $32,000. This vehicle is expected to depreciate in value by 8.5% per year.

Which model could be used to calculate the daily depreciation for this vehicle?

V(t)=32,000(0.0233)^t

V(t)=32,000(0.9150)^t

V(t)=32,000(0.9767)t^t

V(t)=32,000(0.9998)^t

Answers

Answer:

V(t)=32,000(0.9767)t^t

Step-by-step explanation:

The correct model which could be used to calculate the daily depreciation for this vehicle is,

⇒ V (n) = 32,000 (0.915)ⁿ

What is mean by Subtraction?

Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.

We have to given that;

Breyelle is planning on purchasing a new sports-utility vehicle.

Here, The list price of the one she is most interested in buying is $32,000.

And, This vehicle is expected to depreciate in value by 8.5% per year.

Hence, the daily depreciation for this vehicle is,

V (n) = 32,000 (1 - 8.5%)ⁿ

V (n) = 32,000 (1 - 0.085)ⁿ

V (n) = 32,000 (0.915)ⁿ

Thus, The correct model which could be used to calculate the daily depreciation for this vehicle is,

⇒ V (n) = 32,000 (0.915)ⁿ

Answers

1. Greatest common factor (GCF) would be 15, so the answer would be C, 15(x+2)

2. You are able to distribute -5, and you get -5x when it goes into x, and you get positive 10 because it is a negative times a negative. So the answer would be B, -5x + 10

3. On this type of problem, when there is a negative in the middle, you MUST turn it positive. This means you distribute the negative, and everything on the right of the minus sign changes to negative or positive. So it would change to -
(8x-6)+(x-4)
When you add, you get 9x-10, which is C.

4. Simply just add these two, which is what we got to on the last problem, and you get 20x-6, which is choice A.

5. For this, you substitute the numbers in the equation. So it would be -
2(5)-4(-1)
This would equal 14, which is A.

6. You substitute 4 for x, so it would be -
4^2 + 5
4 • 4 + 5
16 + 5
21, Choice B

7. When you combine like terms here, the 3y’s cancel out because they equal each other, so the answer would just be 19, which is A.

The answers for the given Expression are;

1) 15(x+2)

2) -5x + 10

3) 9x - 10

4) 20x - 6

5) 14

6) 21

7) 19

What is an Expression?

Numbers, symbols and operators (such as and times) grouped together that show the value of something.

Given are the Expressions to solve;

1) 15x + 30

GCF for this Expression is 15 therefore

15x + 30 = 15(x+2)

2) -5(x - 2) = -5 + 10

3) (8x - 6) - (-x + 4) = 8x - 6 + x - 4 = 9x - 10

4) (11x - 2) + (9x - 4) = 20x - 6

5) 2x - 4y when x = 5 and y = -1

2x - 4y = 2*5 - 4*(-1) = 14

6) x² + 5 when x = 4

4² +5 = 16 + 5 = 21

7) -3y + 12 + 3y + 7 = 19

Hence, The Answers are :

1) 15(x+2)

2) -5x + 10

3) 9x - 10

4) 20x - 6

5) 14

6) 21

7) 19

Noralie has a home-based business putting on children’s parties. She charges $45 to design the party and then $5.50 per child. Write a function rule that relates the total cost of the party to the number of children n.

f(n) = 5.5 – 55n

f(n) = 5.5n – 55

f(n) = 5.5 + 45n

f(n) = 45 + 5.5n

Answer:

The answer would be C because n is the number of children and it costs $5.50 per child plus an extra design fee of $45

Step-by-step explanation:

Design = $45

rate per child = $5.50

number of children, x

total cost, f(x) = $5.5x + $45

Renting jet skis from splash of fun costs $25.00 per hour with no one-time fee. the cost to rent a jet ski depends on the total number of hours, h, rented. How many hours must you rent a jet ski for the cost to be the same at jerry's water sport and at splash of fun?

Answers

Answer:

1.6 hours

Step-by-step explanation:

The computation of the number of hours is shown below:

For water sports

= 20x + 8

And,For splash of fun

= 25x

Now the cost of both would be same

i.e.

20x + 8 = 25x
