a What equation can you use to find the distance of the flowerbed from the hive?

b. How far is the flowerbed from the hive?

In ** linear equation, **864 is distance the flowerbed from the hive .

**What are a definition and an example of a linear equation?**

a) The equation is so called "time equation"

D%2F12 + 16*60 + D%2F8 = 19*60 seconds

(b) To determine the distance D, solve the equation

D%2F12 + D%2F8 = 19*60 - 16*60 = 3*60,

Choose two statements that are true for this expression

I think C and D but I’m not sure

Find the values of a,b and c that would make the statements true.

1) (ax+2)(5x+b)=10x^2+bx+c

The **values **of a, b and c are a = 2, b = -10 and c = -20

The **equation **is given as

(ax + 2)(5x + b) = 10x^2 + bx + c

Open the brackets

So, we have

5ax^2 + 10x + abx + 2b = 10x^2 + bx + c

By comparing the above **equation**.

We have the following **set **of equations

5a = 10

10 + ab = b

2b = c

By solving the equations, we have

a = 2

Substitute a = 2 in 10 + ab = b

10 + 2b = b

So, we have

b = -10

Substitute b = -10 in 2b = c

2(-10) = c

Evaluate

c = -20

Hence, the **values **of the **variables **are a = 2, b = -10 and c = -20

Reflect the given triangle over the y - axis [[3,6,3],[-3,3,3]]

By using a **reflection** over the y-axis, the **coordinates** of the **image** of the **triangle** are (- 3, - 3), (- 6, 3) and C'(x, y) = (- 3, 3).

How to determine the coordinates of the vertices of a triangle by rigid transformations

**Rigid transformations** are transformations applied on **geometric loci** such that the form of the construction is not altered. **Reflections** over the **y-axis** are examples of **rigid transformations**. In this problem we need to apply this kind of transformation on the three **vertices** of the **triangle**: A(x, y) = (3, - 3), B(x, y) = (6, 3), C(x, y) = (3, 3).

The reflection over the y-axis is described by the following formula:

P'(x, y) = P(x, y) + (- 2 · p, 0)

Where:

P(x, y) - Original pointP'(x, y) - Resulting pointp - x-Component of P(x, y).If we know that A(x, y) = (3, - 3), B(x, y) = (6, 3) and C(x, y) = (3, 3), then the image of the vertices of the triangle:

A'(x, y) = (3, - 3) + (- 6, 0)

A'(x, y) = (- 3, - 3)

B'(x, y) = (6, 3) + (- 12, 0)

B'(x, y) = (- 6, 3)

C'(x, y) = (3, 3) + (- 6, 0)

C'(x, y) = (- 3, 3)

Now we present the picture of the two triangles.

The **coordinates** of the **image** of the **triangle** are A'(x, y) = (- 3, - 3), B'(x, y) = (- 6, 3) and C'(x, y) = (- 3, 3).

A shirt that normally costs $30 is on sale for

$21.75. What percent of the regular price is

the sale price?

**Answer:**

72.5%

**Step-by-step explanation:**

Hello!

We can find the percentage by **dividing** the **sale** price by the **original** price, then **multiplying** that by **100**.

The percentage is **72.5%**.

A store has two types of animal feed available. Type A contains 3 pounds of oats and 3 pounds of corn per bag. Type B contains 1 pound of oats and 7 pounds of

corn per bag. A farmer wants to combine the two types so that the resulting mixture has at least 18 pounds of oats and at least 54 pounds of corn. The store

only has 11 bags of type A feed and 12 bags of type B feed in stock. Type A costs $4 per bag, and type B costs $1 per bag. How many bags of each type should

the farmer buy to minimize her cost?

Note that the ALEKS graphing calculator can be used to make computations easier.

Type A feed:

Type B feed:

bag(s)

bag(s)

The farmer will **purchase** five bags of kind A and six bags of type B.

Per bag, Type A includes 9 pounds of oats and 3 pounds of maize.

Per bag, Type B includes 2 pounds of oats and 10 pounds of maize.

The farmer is looking for a** blend** that comprises at least 57 pounds of oats and 75 pounds of maize.

Allow the farmer to mix type A feed = x pounds.

and feed type B = y pounds

(9x + 2y) pounds of oats when blended

Corn amount when **combined**: (3x + 10y) pounds

Oats equation: 9x + 2y = 57 ———— (1)

Corn equation: 3x + 10y = 75 ————- (2)

Subtract equation (2) from equation (2) by multiplying it by three (1)

3(3x + 10y) - (9x + 2y) = 75×3 - 57

9x + 30y - 9x - 2y = 225 - 57

28y = 168

y = 6 bags

**derived** from the equation (1)

9x + 2×6 = 57

9x + 12 = 57

9x = 57 - 12

9x = 45

x = 5 bags

Because the business has 15 bags of each sort, each bag costs $4.

As a result, the cost of 5 bags of type A and 6 bags of type B is = (54) + (64)

= 20 + 24

= $44

The farmer intends to buy** five** bags of kind A and **six** bags of type B.

Solution : A coin is tossed 3 times then

Sample space = [HHH, HHT, HTH, THH, TTH, THT, HTT, TTT]

Total number of ways = 2 × 2 × 2 = 8

Favorable Cases = 7

P (A) = 7/8

**Probability ** (of getting at least one head) = 1 – P (no head)⇒ 1 – (1/8) = 7/8

Example 2 : Three red and four black balls are contained in a bag. Randomly, one ball gets taken out of the bag. Determine the **probability **that the drawn ball is

(i) black

(ii) not black

Solution :

If triangle LMN has an obtuse angle at vertex M, which statements could be true? Check all that apply.

Triangle LMN is an obtuse angle then, **the angle at vertex L is acute, the angle at vertex N is acute.**

The triangle LMN is an obtuse angle at the vertex M. So by the definition of obtuse angle triangle LMN is an obtuse angle.

As ∠M is an obtuse angle

So 90° < m∠M < 180°

By the **property of a triangle**,

m∠L + m∠M + m∠N = 180°

m∠M = 180° - (m∠L + m∠N)

90° < 180° - (m∠L + m∠N) < 180°

90° - 180° < -(m∠L + m∠N) < 0

-90° < -(m∠L + m∠N) < 0

90° >(m∠L + m∠N) > 0

**90° > m∠L and 90° > m∠N**
