Answer:

380 square inches

Step-by-step explanation:

We are given the measurements of the Rectangular Prism as

8 inches by 9 inches by 10 inches

Where based on the order of arrangement:

8 inches = Length

9 inches= Width

10 inches = Height

Step 1

Find the amount of wrapping paper needed

Perimeter = 2L + 2W

= 2 × 8 + 2 ×9

= 16 + 18

= 34 inches

Base = L × W

= 8 × 9

= 72 inches

Surface Area of the Rectangular Prism =PH + 2B

Where P = Perimeter

H = Height

B = Base

= 34 × 10 + 2× 72

= 340 + 144

= 484 square inches

The area of the Rectangular prism = 484 square inches

Step 2

So we were told that she used wrapping paper the measured 2 feet by 3 feet.

We would convert the values in feet to inches

1 ft = 12 inches

Length = 2 ft = 2 × 12 = 24 inches

Width = 3 ft = 3 × 12 = 36 inches

We find the area of the wrapping paper

Length × Width = 24inches × 36 inches = 864 square inches.

Step 3

The amount of square inches of wrapping paper left over is calculated as:

Area of the wrapping paper used - Area of the Rectangular prism

= 864 square inches - 484 square inches

= 380 square inches.

Therefore, the amount of square inches of wrapping paper left over is 380 square inches.

Answer:

x = 6

Step-by-step explanation:

2x - 5 = 7

Add 5 on both sides.

2x - 5 + 5 = 7 + 5

2x = 12

Divide both sides by 2.

2x/2 = 12/2

x = 6

Answer:

The yearly growth percentage is 5%

The worth of the company in 2010 is 433 million of dollars approximately

Step-by-step explanation:

The annual growth percentage;

We can write the equation of w as follows;

W = 266 (1 + 0.05)^t

Compare this with ;

W = I(1 + r)^t

Where W is the worth at a particular year

I is the initial worth at year 2000

r is the rate of increase per year

and t is the time since 2010

where it is the 0.05 that represents the yearly growth percentage (r)

0.05 as a percentage is 5/100 which is 5%

Now, we want to calculate the worth of the company in the year 2010

The first thing to do here is to calculate the value of t.

The value of t is the difference between the years 2000 and 2010 and that is 2010-2000 = 10 years

Now to find the worth at 2010, simply substitute that value of t = 10 in the equation

Thus;

W = 266(1.05)^10

W = 433.2859707228

Which is approximately 433

Answer:

The constant term is 240. It represents the initial daily revenue.

Step-by-step explanation:

It is given that Tico's Taco Truck is trying to determine the best price at which to sell tacos, the only item on the menu,  to maximize profits.

The owner can calculate the daily revenue using the polynomial  expression

where x is the number of $1 increases in the taco price.

Constant term does not contain any variable.

In the given expression 240 is free from variable x. So, the constant term is 240.

The value of expression is 240 for x=0. Since x is the number of $1 increases in the taco price, therefore 240 is the daily revenue when the taco price is not increased or the taco price increased by 0.

Therefore the constant term is 240 and it represents the initial daily revenue.

Answer:

r = -4

Step-by-step explanation:

If M is the midpoint of DE, that would mean that the distance from M to D and M to E would be the same.

This creates the equation 1-8r=13-5r.

Now it's just simple algebra.

You add 8r to both sides, creating 1=13+3r. Then, you subtract 13 from both sides, getting 3r=-12. Dividing both sides by 3 and solving for r, you get r=-4.

Checking our answer, you see that 1-8(-4)=1-(-32)=1+32=33, and 13-5(-4)=13-(-20)=13+20=33.

Answer: The answer is given below

Step-by-step explanation:

From the question, we are informed that the money m (in £) Xavier has to spend each week is his wage w (in £) subtract the tax t (in £) he pays on his income. Therefore, the formula for the money he can spend will be:

m = w - t

The amount of money that he has to spend if he earns £120 a week and pays £41 in tax will be:

m = w - t

m = £120 - £41

m = £79

Answer:

(B)the alternate interior angles theorem.

Step-by-step explanation:

The diagram for the question is attached below:

In the diagram:

BC is parallel to AD; and

AB is parallel to DC.

Effectively, the shape is a parallelogram.

The Alternate Interior Angles Theorem states that, when two parallel lines are cut by a transversal, the resulting alternate interior angles are congruent.

Therefore:

∠BCA ≅ ∠DAC and ∠BAC ≅ ∠DCA by the alternate interior angles theorem.

Answer:

14 units

Step-by-step explanation:

All we have to pay attention to in this problem is B, so we can ignore the rest of the triangle. B is 5 units directly to the left of line l, meaning that B' must be 5 units to the right of line l. This would put B' 2 units to the left of line m. That means that B" would be 2 unit to the right of line m, as that is how reflections work. Adding up all of the difference in units you have a 10 unit shift from B to B', and then a 4 unit shift from B' to B". Now adding 4+10=14 units.

Answer:

tanΘ = [tex]\frac{3}{4}[/tex]

Step-by-step explanation:

tanΘ = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{6}{8}[/tex] = [tex]\frac{3}{4}[/tex]

Question:

If cos(θ) =-8/17 and sin(θ) is negative, then sin(θ) = ___  and tan(θ) =___.

Answer:

[tex]Sin\theta = \frac{-15}{17}[/tex]

[tex]Tan\theta = \frac{15}{8}[/tex]

Step-by-step explanation:

Given

cos(θ) =-8/17

Required

sin(θ) = __

tan(θ) =__

The first step is to determine the length of the third side

Given that

[tex]cos(\theta) = \frac{Adj}{Hyp}[/tex]

Where Adj and Hyp represent Adjacent and Hypotenuse

[tex]cos(\theta) = \frac{-8}{17}[/tex]

By comparison

[tex]Adj = -8\ and\ Hyp = 17[/tex]

Using Pythagoras

[tex]Hyp^2 = Adj^2 + Opp^2[/tex]

By Substitution

[tex]17^2 = (-8)^2 + Opp^2[/tex]

[tex]289 = 64 + Opp^2[/tex]

Subtract 64 from both sides

[tex]289 - 64 = 64 - 64 + Opp^2[/tex]

[tex]225 = Opp^2[/tex]

Take square roots of both sides

[tex]\sqrt{225} = \sqrt{Opp^2}[/tex]

[tex]\sqrt{225} = Opp[/tex]

[tex]15 = Opp[/tex]

[tex]Opp = 15[/tex]

The question says that sin(θ) is negative; This implies that θ is in the third quadrant and as such

[tex]Opp = -15[/tex]

From trigonometry

[tex]Sin\theta = \frac{Opp}{Hyp}[/tex]

[tex]Sin\theta = \frac{-15}{17}[/tex]

Also from trigonometry

[tex]Tan\theta = Sin\theta / Cos\theta[/tex]

[tex]Tan\theta = \frac{-15}{17} / \frac{-8}{17}[/tex]

[tex]Tan\theta = \frac{-15}{17} * \frac{-17}{8}[/tex]

[tex]Tan\theta = \frac{-15 * -17}{17 * 8}[/tex]

[tex]Tan\theta = \frac{15 * 17}{17 * 8}[/tex]

[tex]Tan\theta = \frac{15}{8}[/tex]

Let's start first with sin(x+y) :

Now with sin(x)+sin(y) :

We can see that both expressions are far away from being equal

We can prove the given expression, sin(x + y) ≠ sin x + sin y by taking the value of x and y as 90 respectively.

Trigonometry is a branch of mathematics that deals with the relationship between the sides and angles of a right-angle triangle. The trigonometric ratio is defined as the ratio of the pair of a right-angled triangle.

It is given that the expression is"sin(x + y) sin(x+y)

Suppose, x=0 and y=90

We have to prove the following expression,

sin(x + y) ≠ sin x + sin y

Left-hand side,

=sin(x + y)

=sin(90+90)

=sin 180

=0

Right-hand side,

=sin x + sin y

=sin90+sin90

=1+1

=2

As a result,

sin(x + y) ≠ sin x + sin y

Thus, we can prove the given expression, sin(x + y) ≠ sin x + sin y by taking the value of x and y as 90 respectively.

Answer:

The quantity of oil in the tank is 12,000 liters

Step-by-step explanation:

Firstly, we find the volume of the tank.

The tank is a cuboid, so we find the volume of a cuboid.

Kindly understand that when finding the volume of the cuboid, we shall not use the height of 3m.

This is because the tank is not full but it is to a height of 1.2m

So mathematically, the volume is calculated as follows;

V = l * b * h

where b = 5m , l = 2m and h = 1.2m

Thus the volume would be ;

V = 5 * 2 * 1.2

V = 12 m^3

But that’s not the quantity of oil.

From the question, 1 cubic meters contains 1000 liters of oil

So 12 cubic meter will contain = 12 * 1000 = 12,000 liters of oil
