**Answer:**

Angles opposite one another that share a vertex are called vertical angles.

When one of these angles undergo a rigid transformation so that it fits exactly over the other, we know that the two angles are congruent

When two parallel lines are crossed by another line called the transversal the angles created inside the parallel lines but on opposite sides of the crossing lines are called alternate interior angles. Angles of this type have the same measurement as one another. Two figures are similar if one can fit exactly over the other after rigid transformations and dilations

**Step-by-step explanation:**

Vertically opposite angles are always equal (congruent)

The transversal line is the line that crosses two or more parallel lines

Alternate interior angles formed by two parallel lines crossed by a common transversal, are congruent

Two plane geometric figures are similar if they their corresponding interior angles are congruent

A train travels 1 kilometre in 1 minute 20 seconds. Picture of steam train Question prompt At this rate, how many kilometres will the train travel in 1 hour?

**Answer:**

45km

**Step-by-step explanation:**

Distance covered in 1min 20sec (80sec) = 1km

Distance covered in 1 min (60sec) = 1km/80sec

Distance covered in 1Hr (3600sec) = (1/80)*3600 = 45km.

Last week, Juliet ran 22 kilometers. This week, she plans to run 2\frac{2}{5}2 5 2 times as far as last week. How many kilometers does Juliet plan to run this week?

**Answer: 52.8 kilometers **

**Step-by-step explanation:**

This week she plans to run 2²/₅ times as much as last week.

If she ran 22 kilometers last week, then multiple 22 by 2²/₅ to find out the number of kilometers to run this week.

First convert the improper fraction to a proper one:

2²/₅ = 12/5

= 12/5 * 22

= 264/5

**= 52.8 kilometers **

Hi, can someone help me with my math homework? I just need help with B.

**Answer:**

8

**Step-by-step explanation:**

========================================================

Explanation:

Let's convert the mixed number 5 & 1/3 to an improper fraction.

The formula to use is

a & b/c = (a*c + b)/c

So,

a & b/c = (a*c + b)/c

5 & 1/3 = (5*3 + 1)/3

5 & 1/3 = 16/3

Imagine you had 16 pieces of candy, and imagine you wanted to divide that up amongst 3 friends. Each friend would get 15/3 = 5 whole pieces. There would be 1 candy left over. The 5 and 1 help then form the 5 & 1/3. So this is one way to visualize how 5 & 1/3 is the same as 16/3.

Another way to see why this works is to note how 16/3 = 5.333 approximately. The '5' before the decimal point is the whole part of the mixed number 5 & 1/3; the decimal portion 0.333 is the approximate value of the fractional part 1/3.

------------------

The total length of fencing needed is 16/3 yards. Each section is 2/3 of a yard long. Since both denominators are "thirds", we can ignore them. An equivalent problem is this: "He needs 16 yards of fencing and each section is 2 yards long"

Based on the new problem without fractions involved, we can see that he'll need 16/2 = **8 sections in total.**

You should find that dividing (16/3) over (2/3) will lead to **8** as well. You could say this:

(16/3) divide (2/3) = (16/3)*(3/2) = (16*3)/(3*2) = 48/6 = **8**

-------------------

An alternative method:

Let's start with 2/3 of a yard. That doubles to 4/3 which is the same as 1 & 1/3. Think of it as 4/3 = (3+1)/3 = 3/3+1/3 = 1+1/3 = 1 & 1/3.

Next, we'll double 1 & 1/3 to land on 2 & 2/3. You simply multiply each '1' by 2 to end up with those '2's shown.

Now we'll double 2 & 2/3 like so:

2*(2 & 2/3) = 2*(2 + 2/3) = 4 + 4/3 = 4 + (1+1/3) = 5 + 1/3 = 5 & 1/3

The act of doubling exactly three times leads to us ultimately multiplying by 2*2*2 = **8**, so **he** **needs 8 sections** that are each 2/3 of a yard long.

-------------------

Whichever method you prefer, **the final answer is 8 sections.**

Determine whether the following statement is true or false.

The graph of f(x) = (x + 2)2 + 4 has its vertex at (2,4).

Choose the correct answer below.

O True

0 False

**Answer:**

**Step-by-step explanation:**

No it doesn't. When you get stuck on a question like this one, you should go to Desmos and graph the equation. I've done that for you.

Correctly stated the equation should read f(x) = (x + 2)^2 + 4

As you can see from the graph the vertex is at -2,4. To find the x value of the vertex, create a small equation

x + 2 = 0

x = - 2

That will turn what is inside the brackets into 0. The value for x is always what will turn (x + a) to zero.

For which value of theta is sine theta = negative 1?

A unit circle is shown. A radius with length 1 forms angle theta in the first quadrant.

StartFraction pi Over 2 EndFraction

Pi

StartFraction 3 pi Over 2 EndFraction

2 pi

**Answer:**

**1) 270 degrees**

**2) pi/4 rad**

**Step-by-step explanation:**

1.) For which value of theta is sine theta = negative 1?

Given

sintheta = -1

theta = arcsin(-1)

theta = -90degrees

Since sin is negative in the third and 4th quadrant

In the third quadrant, theta = 180 + 90 = 270degrees

In the fourth quadrant, theta = 360 - 90 = 270 degrees

**Hence the required value of theta is 270degrees**

2) Given the radius of the circle to be 1, the y axis value will also be 1 units

Opposite = 1

adjacent = 1

hyp = √1²+1²

hyp = √2

sin theta = opp/hyp

sin theta = 1/√2

theta = arccsin(1/√2)

theta = 45 degrees

Express in radians

45 degrees = pi/4 radians

**Hence the required angle in the first quadrant is pi/4 rad**

**Answer:**

3pi/2

**Step-by-step explanation:**

Tavon has a gift card for $80 that loses $3.50 for each 30-day period it is not used. He has another gift card for $70 that loses $3 for each 30 day period it is not

aWrite and solve an equation for the number of 30-day periods until the value of the gift cards will be equal

b. What will the value of each card be when they have equal value?

a. If x is the number of 30-day periods, then the equation can be used to find the number of 30 day periods until the values of the gift cards will be equal.

(Type an equation. Use integers or decimals for any numbers in the equation.)

**Answer:**

*(a). 20 ; (b). $10.00 ;*

**Step-by-step explanation:**

** (a).** 70 - 3x = 80 - 3.50x

- 3x + 3.50x = 80 - 70

0.5x = 10

x = 10 ÷ 0.5

x = * 20* ( 30-day periods )

** (b).** $70.00 - $3.00(20) =

The number of days will be 20 **days**. Then the **values **of the gift cards will be **equal **and will be $10.

The distribution of weights to the **variables **involved that establishes the equilibrium in the **calculation **is referred to as a result.

Tavon has a **gift card **for $80 that **loses **$3.50 for each 30-day period it is **not **used. He has another gift card for $70 that **loses **$3 for each 30 days period it is **not used**.

Let y be the **amount left **of gift cards after x days and x be the number of **days**. Then the **equation **will be

y = 80 - 3.5x ...1

y = 70 - 3x ...2

From **equations **1 and 2, we have

80 - 3.5x = 70 - 3x

0.5x = 10

x = 10 / 0.5

x = 20 days

The **values **of the gift cards will be **equal **and will be

y = 80 - 3.5(20)

y = 80 - 70

y = $10

The **values **of the gift cards will be **equal **and will be $10.
