**Answer: L=45, W=9**

**Step-by-step explanation:**

Perimeter P=108 so if L=5W,

P=2(L+W)=2(5W+W)=2(6W)=12W

108=12W

W=108/12=9

L=5*9=45

The electric generator has an efficiency of approximately 66.67%, which means that 66.67% of the input energy is converted into usable electrical power.

The question wants to know about the **efficiency** of an **electric generator**. The efficiency of any engine or generator is defined as the ratio of useful energy output to the energy input. In this case, the energy input to the generator is 120 hp (horsepower) and the useful energy output (i.e electrical power) is 80 hp.

The formula used to calculate the efficiency is: Efficiency = (**useful energy output** / **energy input**) * 100% , Using this formula, the efficiency of the generator would be (80 / 120) * 100% = 66.67 % .

This means that 66.67% of the energy supplied to the generator is successfully converted into electrical power, while the rest is likely lost as heat or other forms of non-usable energy.

**Answer:**

B.

**Step-by-step explanation:**

GIven that and , and that point M is the midpoint of AB, the midpoint can be determined as a vectorial sum of A and B. That is:

The location of B is now determined after algebraic handling:

Then:

Which corresponds to option B.

The **coordinate **of **point **B will be (4, -2). Then the **correct **option is **B**.

**Coordinate **geometry is the study of **geometry **using the points in **space**. Using this, it is **possible **to find the distance **between **the **points**, the dividing line is m:n **ratio**, finding the **mid**-**point **of the line, etc.

Point A is **located **at (-2, 2), and **point **M is **located **at (1,0).

If **point **M is the **midpoint **of AB.

Then the **location **of point B will be

We know that the **mid section **formula

Then the **formula **can be **written **as

x₂ = 2x - x₁ and y₂ = 2y - y₁

Then we have

x₂ = 2 × 1 + 2

x₂ = 4

y₂ = 2 × 0 - 2

y₂ = - 2

Then the **coordinate **of **point **B will be (4, -2).

Thus, the **correct **option is **B**.

Based on the table, the values relating t and e with their **viability** is given by:

- e = 330 (not
**viable**). - e = 265 (
**viable**). - e = 0 (
**viable**).

A **linear function** can be defined as a type of** function** whose equation is graphically represented by a straight line on the cartesian coordinate.

An **average rate** of **change** is also referred to as slope and it can be defined as a type of **function** that describes the** average** rate at which a quantity **changes** (decreases or increases) with respect to another quantity, over a period of time.

From the table, we would determine which values are **viable** points as follows:

At a = -2, we have:

e = 300 - 10t

e = 300 - 10(-2)

e = 300 + 30

e = 330 (not **viable**).

At b = 3.5, we have:

e = 300 - 10t

e = 300 - 10(3.5)

e = 300 - 35

e = 265 (**viable**).

At c = 10, we have:

e = 300 - 10t

e = 300 - 10(30)

e = 300 - 300

e = 0 (**viable**).

**Answer:**

A 2-column table with 3 rows. The first column is labeled time (t) with entries negative 2, 3.5, 30. The second column is labeled Elevation(e) with entries a, b, c.

Rory is staying in a cabin on a hill 300 feet above sea level. She walks down the hill to the water’s edge. The equation of her average change in elevation over time is e = 300 – 10t, where t is the time in minutes since she left the cabin, and e is her elevation with regard to sea level. Which values are viable points, and what are their values in the table relating t and e?

a =

✔ not viable

b =

✔ 265

c =

✔ 0

**Step-by-step explanation:**

**Answer:**

**Step-by-step explanation:**

Hello, let's do it step by step and see what we can find.

We assume that M is different from 0, otherwise we could find several different solutions I would think.

It means that S + M is greater than 10, otherwise the number of digit of the result would have been 4 and not 5.

The only possible number for M is then 1. **M = 1**

But then, S can only by 9, otherwise S + 1 < 10. **S = 9**

S + 1 = 10 + O if there is no carry over, so S = 9 + O

1 + S + 1 = 10 + O if there is a carry, so S = 8 + O

So O = 0 or O = 1. Wait !? M is already equal to 1 so O must be 0

E cannot be equal to N so 1 + E = N, meaning that there must be a carry over from column second from the right.

and E < 9 as we know that there is no carry over from column 3 from the right.

N + R = 10 + E => 1 + E + R = 10 + E => R = 9, impossible, as S=9

or 1 + N + R = 10 + E => 1 + 1 + E + R = 10 + E => **R = 8**

And there is a carry over from the column 1 from the right, so:

Y cannot be 0 or 1, as already used so D + E > 11

8 and 9 are already taken so we could have 7 + 5 = 12, 7 + 6 = 13 and that's it.

It means that E is 7 or D is 7.

If E is 7 then E+1=9=N, impossible, so **D = 7**

Then, E is 5 or 6

if E = 6 E + 1 = N = 7, impossible, so **E = 5** and **N = 6**.

And 7 + 5 = 12 so **Y = 2**.

Hope this helps.

t/3-1/2=t+3/9

**Answer:**

-1.25

**Step-by-step explanation:**

t÷3-1÷2 = t÷1+3÷9

2t-3÷6 = 9t+3=9

18t - 27 = 54 + 18

18t -54t = 18 + 27

-36t = 45

Divide through by -36

t = -1.25
