Answer:

Q5: S.A = 216 cm²

Q6: S.A = 254 cm²

Step-by-step explanation:

Q5:

Surface area of a cube = 6a²

a = 6 cm

Plug in the value of a

Surface area of the cube = 6(6²)

= 6(36)

S.A = 216 cm²

Q6:

Given:

Length (L) = 9 cm

Width (W) = 4 cm

Height (H) = 7 cm

Required:

Surface area

Solution:

Surface area of the rectangular prism = 2(LW + LH + HW)

Plug in the values

S.A = 2(9*4 + 9*7 + 7*4)

= 2(36 + 63 + 28)

= 2(127)

S.A = 254 cm²

Answer:

Part A

1. After 4 weeks of work, Jeremy has saved 300

2. Jeremy worked 8 weeks in order to save $600

3. For every one week of work, Jeremy saved 75 dollars

4. If Jeremy works 15 weeks, then he can expect to save 1,125 dollars

Part B

1. Saeed orders 15 meals and his total cost of delivery is $24

2. Saeed paid $32 to have 20 meals delivered

3. For every meal delivered, Saeed is charged $1.6

4. If Saeed pays $19.20 in delivery fees then he ordered 12 meals

Step-by-step explanation:

Part A

The given graph gives the proportional relationship between total amount saved and the number of weeks worked

1. Reading from the graph, at the point where the vertical line from point 4 touches the line of the graph, an horizontal line to the vertical y-axis touches the y-axis at 300

Therefore;

After 4 weeks of work, Jeremy has saved 300

2. The point where an horizontal line from point 600 on the vertical y-axis touches the line of the graph, a vertical line drawn to the horizontal, x-axis touches the x-axis at 8

Therefore;

Jeremy worked 8 weeks in order to save $600.

3. The rate of change of the amount saved to the number of weeks worked, 'm', for the given proportional relationship (straight line relationship, passing through the origin) is given as follows;

Rate of change, m = Constant = y/x

∴ Rate of change of the amount saved to the number of weeks worked = (300-0)/(4 weeks- 0 week) = 75/week

Therefore;

For every one week of work, Jeremy saved 75 dollars

4. The amount Jeremy would have saved in 15 weeks, 'A', is given as follows;

A = m × n

Where;

m = The rate of change of the amount saved to the number of weeks worked = 75/week

n = The number of weeks worked

∴ A = 75/week × 15 = $1,125

Therefore;

If Jeremy works 15 weeks, then he can expect to save 1,125 dollars

Part B

From the graph, we have;

1. From the graph there is a proportional relationship between the total cost of delivery and the number of meals

At the point a vertical line drawn to the line of the graph from 15 on the horizontal axis (number of meals), a horizontal line drawn to the vertical y-axis touches the y-axis at 24

Therefore;

1. Saeed orders 15 meals and his total cost of delivery is $24

2. From the point where the horizontal line from 32 on the vertical axis touches the linear graph of the relationship between the total cost of delivery and the number of meals, a vertical line drawn down to the horizonal axis touches the horizontal x-axis at 20

Therefore;

Saeed paid $32 to have 20 meals delivered

3. The rate of change of the total cost of delivery to the number of meals, 'm', is given as follows;

m = y/x (for proportional relationships)

Taking any corresponding 'x' and y-values

m = 16/10 = 32/20 = 24/15 = 1.6 Dollars/meal

Therefore;

For every meal delivered, Saeed is charged $1.6

4. From m = y/x = 1.6

When y = $19.20

x = y/m = $19.20/($1.6/meal) = 12 meals

Therefore;

If Saeed pays $19.20 in delivery fees then he ordered 12 meals.

Answer:

The horizontal value in a pair of coordinates: how far along the point is. The X Coordinate is always written first in an ordered pair of coordinates (x,y), such as (12,5). In this example, the value "12" is the X Coordinate.

Angel b=angle a+angle c-180

We have now proven that all three angles of ΔABC have a measure of 60 degrees. Therfore, ∠C must have a measure of 60 degrees

Answer:

x = -15, angle b = 115, angle c = 30.

Step-by-step explanation:

The 3 sides of a triangle add up to 180, so the equation will be

35 - 5 - 8x - 2x = 180

30 - 10x = 180

Subtract 30 from both sides.

-10x = 150

Divide by -10.

x = -15.

Finding angle b:

-5 - 8x

-5 - 8(-15)

-5 + 120

115

Finding angle c:

-2x

-2(-15)

30

To check it, we add angle a, angle b, and angle c together.

35 + 115 + 30

150 + 30

180.

Answer:

67°

Step-by-step explanation:

CHECK THE ATTACHMENT FOR THE FIQURE

From, trigonometry

tan(θ) = opposite/ adjacent

✓The helicopter is 665 feet from ground.

✓Distance of the helicopter and the line of sight of the girl will be the OPPOSITE SIDE, which is

(665ft - 5 ft)

= 600 ft

✓ from the figure, we can see the distance on the Horizontal side which is the ADJACENT SIDE as ( 280 ft)

✓angle of depression can be calculated as

tan(θ) = opposite/ adjacent

tan(θ)= (660/280)

tan(θ)= 2.357

tan-1=(2.357)

θ= 67°

Hence, angle of depression is 67°

Answer:

1. x = 58

2. x = 44

Step-by-step explanation:

#1:

2x + 5 + x + 2x + 7 + x = 360

Step 1: Combine 2x, x, 2x, and x to get 6x.

6x + 5 + 7 = 360

Step 2: Add 5 & 7 to get 12.

6x + 12 = 360

Step 3: Subtract 12 from both sides

6x = 360 - 12

6x = 348

Step 4: Divide both sides by 6.

x = 348/6

x = 58

#2:

3x + 2 + 2x + 2x + 1 + x + 5 = 360

Step 1: Combine like terms.

8x + 2 + 1 + 5 = 360

8x + 8 = 360

Step 2: Subtract 8 from both sides.

8x = 360 - 8

8x = 352

Step 3: Divide both sides by 8.

x = 352/8

x = 44

Answer:

x = 6.

Step-by-step explanation:

Given:

Daniel bought a bicycle for $80 and a helmet for $20.

Sales tax = 5%

To find:

The total amount of both items including tax.

Solution:

Price of bicycle (excluding tax)= [tex]\$80[/tex]

Price of helmet(excluding tax) = [tex]\$20[/tex]

Price of both items = [tex]\$80 + \$20[/tex]

                                =[tex]\$100[/tex]

Now, the sales tax is 5%. So,

Price of both items (including tax) = [tex]\$100+\dfrac{5}{100}(\$100)[/tex]

                                                        = [tex]\$100+\$5[/tex]

                                                        = [tex]\$105[/tex]

Therefore, the Daniel pays $105 for the two items, including tax.

Answer:

They played 4 games and paid $19

Step-by-step explanation:

4x + 3 = 2x + 11    (You basically have to solve for X)

4x - 2x = 11 - 3      (move like terms together)

2x = 8

x = (8/2)

x = 4

This means they had to play 4 games.

To get how much they paid, just plug 4 into any one of those given equations (They will both give the same answer).

4x + 3 ⇒ 4(4) + 3 = $19

To check if this is true,

2x + 11 ⇒ 2(4) + 11 = $19

Therefore, they paid $19

Hello!

This is a question about multiplying to get a polynomial answer.

Here we can use two strategies, which will get you the same strategy.

One is using a Punnett Square, and the other would be FOILing.

I personally like Punnett Squares, but I will use FOILing for the sake of being online.

FOIL stands for First, Outside, Inside, Last, which describes how the terms should be multiplied.

Let's multiply the first terms.

(-d + e)(4e + d)

[tex]-4de[/tex]

The outside terms.

(-d + e)(4e + d)

[tex]-d^2[/tex]

The inside terms.

(-d + e)(4e + d)

[tex]4e^2[/tex]

The last terms.

(-d + e)(4e + d)

[tex]de[/tex]

Now you just add them together to find the polynomial.

[tex]-d^2+4e^2-4de+de[/tex]

[tex]-d^2+4e^2-3de[/tex]

There are three terms in the product, and the product is degree 2, since the highest degree of the equation (the highest power any term is raised to) is 2.

Hope this helps!
