As Trish and tan were traveling to the state cross country meet, they followed their progress along on a map. The map showed a scale of 1 inch equaling 60 miles. Their route’s total length on the map is 2 1/2 inches long. How far will they be traveling to the meet?￼￼ Show your work.

(60x2)+30 = 150 miles

30 = 1/2 of 60 which is half an inch

60 x2 because he travels 2 inches

30 = 1/2 of 60 which is half an inch

60 x2 because he travels 2 inches

A student says that the solution of 375 = x – 28 is 347. Explain the student’s error and find the correct answer

**Answer:**

x = 403

**Step-by-step explanation:**

We can start off by rewriting the equation as

x - 28 = 375

Next, we can further restate it as

375 + 28 = x

So, all we need to do to find the value of x is add 375 + 28, which is 403

**Student Error**

The student made the error of rewriting the equation incorrectly.

He/She/They subtracted 28 from 375 instead of adding.

Thus, they got 347

In which quadrant does the graph of the sum of

(-3 – 5i) and (2 + 4i) lie?

**Answer:**

Third quadrant

**Step-by-step explanation:**

The complex and real parts can be added separately:

(-3 - 5i) + (2 + 4i) = -1 -i

This shows that the sum would be in the third quadrant of the complex plane as there is negative real and negative imaginary parts.

**Answer:**

27

**Step-by-step explanation:**

3 * 9 = 27

Hope this helps!

**Answer:**

**The bold word help you**

**Step-by-step explanation:**

Consider the numbers 2, 23, 234, 2345, 23456, 234567.

Every number divisible by 9 is divisible by 3. For example, 7425 is divisible by 9, hence it is divisible by 3. However, a number divisible by 3 is not necessarily divisible by 9. For example 6, 12, 15, 21, 24, 30 are all divisible by 3 but none of them is divisible by 9.

**6 is divisible by 3 but not by 9 because 6 is greater than 3 but smaller than 9**

You can represent the measures of an angle and its complement as x °and (90 - x). Similarly, you can

represent the measures of an angle and its supplement as x and (180 - x )º. Use these expressions to

find the measures of the angles described.

The measure of an angle increased by 24° is equal to the measure of its complement.

The measure of the angle is

Jº and the measure of its complement is

**Answer:**

**Step-by-step explanation:**

If x represents the measure of the angle, its complement is 90-x. The problem statement tells us ...

x +24 = 90 -x

2x = 66 . . . . . add x-24

x = 33 . . . . . . divide by 2

**The measure of the angle is 33°**.

__

2)Using J for x in the given complement relation:

**The measure of the complement of J° is (90 -J)°**.

**Answer:**

200 sq cm

**Step-by-step explanation:**

Lateral surface area is the surface area without the bases, or without the top and bottom. So, you just add up the area of the 4 sides.

The front and back are both 10 x 20, so 200 each = 400

The left and right are 5 x 20, so 100 each = 200

The lateral surface area is 200 sq. cm.

Jules has a watch pedometer which counts how many steps (S) he walks in a day. He has measured his step length as 0.7m.

Draw a conversion graph of the distance walked (L) against S to convert up to 10000 steps into metres.

**Answer:**

see attached

**Step-by-step explanation:**

Each step is 0.7 m, so 10,000 steps will be 0.7(10,000 m) = 7,000 m. Of course 0 steps is 0 meters, so the graph is a straight line with a slope of 0.7.

7. Un cuerpo desliza hacia abajo con velocidad constante por un plano inclinado a un ángulo de 22º. Luego es lanzado en sentido contrario por el mismo plano con una velocidad inicial de 4.0 m/s. a) ¿Qué distancia subirá por el plano antes de detenerse? b) ¿Deslizará nuevamente hacia abajo?AYUDAAAA ES PARA HOY!!!

The **distance travelled** across the slant will be -

**h =** **√({4v/g}{cot (22°)})² + {v/g(cos(22°) - 1)}² **and yes it will slide down again.

If we take a single vector we can find a pair of vectors at **right angles** to each other that would **combine** to give the single original vector. This reverse process is called **resolution **or resolving vectors.

Given is that body slides down a **22º **inclined plane with constant speed. It is then thrown in the **opposite direction** by the same plane with an initial velocity of 4.0 m/s.

[A] -

We can write the total distance covered along the slant as a **function** of **[x] **and** [y] components** as -

h = h[x] i + h[y] j

Now -

h[x] = 4tcos(22°)

Now -

F = ma

F = m{dv/dt}

Fdt = mdv

mg sin(22°)dt = mdv

dt = {1/g sin(22°)}dv

∫dt = ∫ {1/g sin(22°)}dv

t = v/g sin(22°)

So, we can write -

h[x] = 4 cos(22°)v/g sin(22°)

**h[x] = {4v/g}{cot (22°)}**

Similarly -

h[y] = 4t'cos(22°)

F = ma

F = m{dv/dt}

Fdt = mdv

N cos(22°) - mg = F

{N cos(22°) - mg}dt' = mdv

{mg cos(22°) - mg}dt' = mdv

{g cos(22°) - g}dt' = dv

dt' = dv/{g cos(22°) - g}

∫dt' = ∫dv/{g cos(22°) - g}

**t' = {v/g(cos(22°) - 1)}**

So -

h[y] = 4 x {v/g(cos(22°) - 1)} x cos(22°)

h[y] = {4v/g(cos(22°) - 1)} cos(22°)

So -

Distance travelled across the slant -

**h =** **√({4v/g}{cot (22°)})² + {v/g(cos(22°) - 1)}²**

[2] -

**Yes**, it will slide down again.

Therefore, the **distance travelled** across the slant will be -

**h =** **√({4v/g}{cot (22°)})² + {v/g(cos(22°) - 1)}² **and yes it will slide down again.

I need help long dividing this equation.

(x^2 - x +5) / (x + 1)

I already know the answer however I’m having a bit of trouble understanding how to get to it. At the second to last operation you come to,

- x^2 + 4x

- x^2 - x

= 5x

I’m having trouble understanding how you get 5x from that? Someone please help!

First, we'll look at the first term of each expression.

---x times what is equal to x^3? = x times **x^2** = x^3

So, we'll multiply everything in the divisor by x^2 and subtract that from the dividend.

x^2(x + 1) = x^3 + x^2

(x^3 + 4x + 5) - (x^3 + x^2)

x^3 - x^3 = 0

0 - x^2 = -x^2

4x - 0 = 4x

5 - 0 = 5

Our new expression is -x^2 + 4x + 5.

So we again ask ourselves, x times what is equal to -x^2? = **-x**

-x(x + 1) = -x^2 - x

And subtract!

(-x^2 + 4x + 5) - (-x^2 - x)

-x^2 - - x^2 = -x^2 + x^2 = 0

4x - - x = 4x + x = 5x

5 - 0 = 5

Our new expression is 5x + 5. Let's ask ourselves once again, x times what is equal to 5x? = **5**.

Multiply, then subtract!

5(x + 1) = 5x + 1

(5x + 1) - (5x + 1) = 0

Now that we have nothing left to divide, let's go back and get our answer.

**x^2 - x + 5**

Notice that when I was dividing, I always looked at the **first **term of the dividend (as the expression changed) and divisor. Whatever comes after the first term doesn't matter at the time.

Hope this helps and if you have any further questions, please let me know! :)

**Answer:**

**Step-by-step explanation:**

** x - 2 ** <--- quotient

**x + 1) x^2 - x + 5** First divide x^2 by x giving x then multiply x + 1 by x:

x^2 + x Now subtract x^2 + x from x^2 - x and bring down +5:

-2x + 5 Now divide -2x by x to get -2 and multiply X+1 by -2 -2x - 2 Subtract:

** 7 **

The result is **x - 2** (see above) remainder** 7**

or you could write it as

**x - 2 + 7/(x + 1)**
