Emily went to a toy store that was selling two Nintendo DS games and four Wii games for a total of $240. Emily bought three DS games and two Wii games and spent $160. What was the price of one Wii game?

Final answer:

To find the wrapping paper needed for a box with given dimensions and one largest face uncovered, calculate the total surface area, subtract the area of the largest face, resulting in 592 square cm of wrapping paper required.

Explanation:

The question concerns calculating the amount of wrapping paper required to cover a box while leaving one of the largest faces uncovered. Given the dimensions of the box are 12 cm, 10 cm, and 11 cm, we can calculate the surface area of each face and sum them up, excluding one of the largest face, which is one with dimensions 12 cm x 11 cm.

Therefore, Xan will need 592 square cm of wrapping paper to cover the box while leaving one of the largest faces uncovered.

Candies

4 red

- Taina doesn't like red candies.

4/4+2+5+1 = 4/12

4/12 is the probability Taina will get a red candy, but we're looking for the opposite.

12/12 - 4/12 = 8/12 = 2/3

The probability Taina will not select a red candy is 2/3.

[tex]r=\theta\sin\theta+\cos\theta[/tex]

[tex]\dfrac{\mathrm dr}{\mathrm d\theta}=\dfrac{\mathrm d(\theta\sin\theta)}{\mathrm d\theta}+\dfrac{\mathrm d(\cos\theta)}{\mathrm d\theta}[/tex]

By the product rule,

[tex]\dfrac{\mathrm d(\theta\sin\theta)}{\mathrm d\theta}=\dfrac{\mathrm d(\theta)}{\mathrm d\theta}\sin\theta+\theta\dfrac{\mathrm d(\sin\theta)}{\mathrm d\theta}=\sin\theta+\theta\cos\theta[/tex]

and

[tex]\dfrac{\mathrm d(\cos\theta)}{\mathrm d\theta}=-\sin\theta[/tex]

So we have

Final answer:

To make x the subject of the equation a = 7x/k - r, add r to both sides, multiply by k, and then divide by 7, resulting in x = k(a + r)/7.

Explanation:

To rearrange the equation a = 7x/k - r to make x the subject, we need to perform a series of algebraic manipulations. Firstly, we add r to both sides of the equation, giving us a + r = 7x/k. Following this, we multiply both sides by k to get rid of the denominator, which results in k(a + r) = 7x. Finally, we divide both sides by 7 to solve for x, which gives us x = k(a + r)/7. This rearrangement shows x as the subject of the original equation.

Answer:

Step-by-step explanation:

Supplementary angles sum to 180°, thus

supplementary angle = 180° - 114° = 66°

The functions f(x) = √16^x and g(x) = ∛64^x increase at the same rate as x increases.

The functions f(x) = √16ˣ and g(x) = ∛64ˣ are related in the way they grow or decrease as x increases. Let's analyze each function:

For the function f(x) = √16ˣ, as x increases, the value of f(x) also increases. This is because when x increases, 16^x becomes larger, and taking the square root of a larger number results in a larger value for f(x).

For the function g(x) = ∛64ˣ, the same logic applies. As x increases, the value of g(x) also increases. This is because when x increases, 64ˣ becomes larger, and taking the cube root of a larger number results in a larger value for g(x).

Therefore, both functions f(x) and g(x) increase at the same rate as x increases. None of the given options accurately describe the relationship between the graphs of f(x) and g(x).

Answer:

It's the second choice.

Step-by-step explanation:

x + (x + 1) + (x + 2) = 30.

Solving for x will give you the smallest digit.

The equation x+(x+1)+(x+2) = 30 is used to find x.

The integers are 9, 10 & 11.

If a, b, c are integers, then the sum of three integers is a+b+c

Let, x be a integer.

Then other two consecutive integers are, x+1 & x+2

Sum of this three integers is x+(x+1)+(x+2)

According to the question,

Sum of this three integers is 30

So, the equation becomes, x+(x+1)+(x+2) = 30

Now, solving, x+x+1+x+2 = 30

                      ⇒ 3x+3 = 30

                      ⇒ 3x = 27

                      ⇒ x = 27/3 = 9

So, (x+1) = 9+1 = 10 & (x+2) = 9+2 = 11

Therefore, the three consecutive integers are 9, 10 & 11

Answer:

x + x + 1 + x + 2 + x + 3 = 4x + 6 = 342

4x = 336

x = 84

The third term is 84 + 2 = 86.

To find the third term in the sequence, we need to determine the first term and the common difference. By setting up and solving equations, we find that the first term is 84 and the common difference is 1. Therefore, the third term in the sequence is 86.

To find the third term in the sequence, we need to determine the first term and the common difference.

Let's assume the first term is 'x' and the common difference is 'd'.

The four consecutive integers can be represented as x, x + d, x + 2d, and x + 3d.

Since the sum of these four integers is 342, we have the equation:

x + (x + d) + (x + 2d) + (x + 3d) = 342

Simplifying this equation, we get:

4x + 6d = 342

Now, we have two variables and one equation, so we need another equation to solve for x and d.

We can use the fact that the integers are consecutive, so the common difference is always 1.

Plugging in the value of d = 1 in the previous equation, we get:

4x + 6(1) = 342

Simplifying further, we get:

4x + 6 = 342

4x = 336

x = 84

Therefore, the third term in the sequence is x + 2d = 84 + 2(1) = 86.

Answer:

a) 18 rows of bricks are needed

b) 2.25 times b

0.375 times (b - 1)

46.875 inches

18 rows

Step-by-step explanation:

* Lets explain how to solve the problem

a)

- The height of each brick is the shortest edge

- The shortest age is 2 1/4 inch ⇒ (2.25 inches)

- If b is the number of the rows of bricks

∴ The height of the bricks = 2.35 × b

- The height of the mortar is 3/8 inches ⇒ (0.375 inch)

- All rows of bricks covered by mortar on top except the last row

- The height of mortar = 0.375 × (b - 1)

- The height of the wall is 1 1/8 (1.125) inches less than 4 feet

∵ 1 foot = 12 inches

∵ 4 feet = 12 × 4 = 48 inches

∴ The height of the wall = 48 - 1.125 = 46.875 inches

- The sum of the total height of bricks and the total height of mortar

 is equal to the height of the wall

∴ 2.25 b + 0.375(b - 1) = 46.875

- By simplify it

∴ 2.25 b + 0.375 b - 0.375 = 46.875

∴ 2.625 b - 0.375 = 46.875

- Add 0.375 for both sides

∴ 2.625 b = 47.25

- Divide both sides by 2.625

∴ b = 18

∴ 18 rows of bricks are needed

b)

* Lets complete the missing

- The total height of the bricks in inches is equal to 2.25 times b

- The total height of the mortar is equal to 0.375 times (b - 1)

-  Their sum is equal to the height of the wall or 46.875 inches

- If I write this as an equation and solve for​ b, then the result is

 18 rows of bricks

To find the number of rows of bricks needed for a wall, we can set up an equation to solve for that number. The equation will involve the heights of the bricks and mortar layers, as well as the height of the wall. Solving the equation will give us the number of rows of bricks needed.

To find the number of rows of bricks needed, we need to determine the total height of the bricks and the total height of the mortar. Let b be the number of rows of bricks. The total height of the bricks in inches is equal to the height of each brick multiplied by the number of rows (b). The total height of the mortar is equal to the height of the mortar layer multiplied by the number of rows minus 1 (b-1). The sum of the heights of the bricks and mortar is equal to the height of the wall, which is 4 feet minus 1/8 inches.

Writing this information as an equation, we have:

(height of the bricks x b) + (height of the mortar x (b-1)) = 4 feet - 1/8 inches

Solving this equation for b will give us the number of rows of bricks needed.
