Answer: D $10.84

Step-by-step explanation:

If the box is a cube and paper is needed to wrap it, then we need to find the surface area of the box then multiply it buy the cost of the wrapping paper.

The surface area of a cube uses the formula 6a^2  where a is any side length.

We know that the box has a side length of 8.5 inches.

SA = 6*8.5^2

SA= 433.5  

Now multiply the surface area by the money.

433.5 * 0.025 = 10.8375  

Round 10.8375 to dollars and cents as it is required.

10.8375 = 10.84

Which means it will cost $10.84 to wrap the box.

Answer:

$10.84

Step-by-step explanation:

The surface area of the moving box is SA = 6s2.

SA = 6(8.5)2

SA = 6(72.25)

SA = 433.50 square inches.

At $0.025 per square inch, it would take 433.50 x (0.025) or $10.84 to wrap this box.

Answer: 1/250

Step-by-step explanation:

Given the recurring decimal : 0.004

Firstly:

Let x = 0.004 - - - (1)

Due to the number of decimals places and value of x;

We multiply (1) by 1000 to obtain an integer

Multiply (1) by 1000

1000x = 4 - - - (2)

From (2) we can solve for x and leave our answer as a fraction.

Divide (2) by 1000 to obtain the value of x

1000x / 1000 = 4 / 1000

x = 1 / 250

Recall x = 0.004

Therefore, x = 0.004 = 1/250

Answer:

20.56 units.

Step-by-step explanation:

Perimeter of the shaded region is the sum of all straight sides and all 4 arcs.

Perimeter of 4 straight sides [tex]=4\times 2=8\text{ units}[/tex]

Perimeter of a arc [tex]=\dfrac{1}{4}\times 2\pi r[/tex]

Perimeter of 4 arcs [tex]=4\times \dfrac{1}{4}(2\pi r)=2\pi r[/tex]

Here, r is the radius. So,

[tex]r=\dfrac{6-2}{2}=\dfrac{4}{2}=2[/tex]

Perimeter of 4 arcs [tex]=2(3.14)(2)=12.56[/tex]

Perimeter of the shaded region = Perimeter of all straight sides + Perimeter of all 4 arcs

                             [tex]=8+12.56[/tex]

                             [tex]=20.56\text{ units}[/tex]

Therefore, the perimeter of the shaded region is 20.56 units.

Answer:  36 three-point field goals

Step-by-step explanation:

To solve this problem, set up a system of equations. Let's call the number of  one-pointers [tex]w[/tex], the number of two-pointers [tex]x[/tex], and the number of three-pointers [tex]y[/tex]. We are trying to find [tex]y[/tex] here. We also know that [tex]w+x+y=85[/tex], because that is the total amount of baskets, and also that [tex]w+2x+3y=184[/tex], which is the total amount of points. We know that there were 22 free throws,  so that means we can take away 22 baskets from the first equation, and also 22 points from the second equation. Now the equations are [tex]x+y=63[/tex]  and[tex]2x+3y=162[/tex]. Solving the equations using our knowledge of systems of equations, you get that [tex]y=36[/tex]. So, 36 is the answer. Let me know if anything was unclear, and I hope this helped.

The number of two-point and three-point field goals they made is 27 and 36, respectively.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Let the number of two points basket be represented by x and the number of three points basket be represented by y.

Now, since the total number of basket is 85, out of which 22 were free throw. Thu, we can write the equation as,

22 + x + y = 85

Solving the equation for x,

x = 85 - 22 - y

x = 63 - y

Further given that the total point made is 184. Therefore, the total number of score can be written as,

22 + 2x + 3y = 184

22 + 2(63 - y) + 3y = 184

22 + 126 - 2y + 3y = 184

y = 36

Substitute the value of y in the first equation,

22 + x + y = 85

x = 85 - 22 - 36

x = 27

Hence, the number of two-point and three-point field goals they made is 27 and 36, respectively.

Answer:

It will take 1 hour and 12 minutes for the two trains to be 192 miles apart

Step-by-step explanation:

The total distance between the two trains is the distance traveled by both trains. The distance traveled by the eastbound train is 85 mph * elapsed time and the distance traveled by the westbound train is 75 * elapsed time.

The combined formula is distance traveled = speed of first train * elapsed time + speed of second train * elapsed time.

Since the elapsed time is equal for both trains then the formula is modified as distance traveled = (speed of first train + speed of second train) * elapsed time.

Solving for the elapsed time

distance traveled = (speed of first train + speed of second train) * elapsed time

192 miles = (85mph + 75 mph) * elapsed time

192 miles = 160 mph * elapsed time

elapsed time = 192 miles / 160 mph

elapsed time = 1.2 hours

elapsed time = 1 hour and 12 minutes

It will take 1 hour and 12 minutes for the two trains to be 192 miles apart.

Answer:

45 square units

Step-by-step explanation:

In the above question, we are given the following values

The ratio of the lengths of the corresponding sides of two regular octagons is 8 to 3.

This means the length of the larger octagon = 8

The length of the smaller octagon = 3

Using scale factor denoted as k and because we are dealing with area of the octagon

k = 3²/8²

The area of the larger octagon is 320 ft².

The area of the smaller octagon s represented as y and is calculated as

k = y/Area of larger octagon

3²/8² = y/320

Cross multiply

8² × y = 3² × 320

y = 3² × 320/8²

y = 45 square units

Area of smaller octagon = 45 square units.

Answer:

A. (x + 2)^2 = 31.

Step-by-step explanation:

x^2 + 4x = 27

x^2 + 4x - 27 = 0

A. (x + 2)^2 = 31

x^2 + 4x + 4 - 31 = 0

x^2 + 4x - 27 = 0

This option corresponds to the given equation, so it is correct.

B. (x + 2)^2 = 43

x^2 + 4x + 4 - 43 = 0

x^2 + 4x - 39 = 0

This does not correspond to the equation.

C. (x + 4)^2 = 31

x^2 + 8x + 16 - 31 = 0

x^2 + 8x - 15 = 0

This does not correspond to the equation.

D. (x+4)^2 = 43

x^2 + 8x + 16 - 43 = 0

x^2 + 8x - 27 = 0

This does not correspond to the equation.

So, your answer is A. (x + 2)^2 = 31.

Answer:

[tex]30[/tex]

Step-by-step explanation:

Here, we will have to use [tex]LCD[/tex] or, least common denominator.

The least common [tex]LCD[/tex] here that we will be using is going to be 30. We can always make sure by multiplying.

[tex]\frac{3}{10}[/tex]*[tex]\frac{3}{3}[/tex][tex]=\frac{9}{30}[/tex]

Our final answer for the first fraction is [tex]\frac{9}{30}[/tex] which could be simplified back to [tex]\frac{3}{10}[/tex].

For the second fraction, we will be multiplying with [tex]\frac{2}{2}[/tex].

[tex]\frac{2}{15}[/tex]*[tex]\frac{2}{2}[/tex][tex]=\frac{4}{30}[/tex].

Again, it simplifies back to [tex]\frac{2}{15}[/tex].

Hence, the [tex]LCD[/tex] is [tex]30[/tex].

Answer: y≤ [tex]\frac{7}{3}x+2[/tex]

Step-by-step explanation:

Since we are given the equation, all we have to do is to fix the inequality. We have four options: <, >, ≤, and ≥. The line in the graph is a solid line. This means the line reaches and is equal to the points on the line. We can automatically eliminate ≤ and ≥. Now, we know the answer is ≤. The shading shows that the answer is less than 7/3x+2. In other words, y≤ [tex]\frac{7}{3} x+2[/tex].

Answer:

121°

Step-by-step explanation:

The sum of the a triangle's angles is 180°

so the missing angle: 180°-(87°+34°) = 59°

so z°= 180°-59°=  121°

Answer:

121º

Step-by-step explanation:

Once interior angles of a triangle sum 180º, the remaining angle is:

34º + 87º + x = 180º

x = 59º

Once ∠x and ∠z are supplementary angles (add up to 180º), ∠z = 121º
