I'll calculate the surface area to answer your question.

Area of the base and top = 2x20x7 = 280 in^2

Area of the frontal and behind faces = 2 x 7x7.5 = 105 in^2

Area of the left and right faces = 2x20x7.5 = 300 in^2

Total area = 280 + 105 + 300

= 685 in^2

The amount of wood needed is 685 in^2

Use inductive reasoning to find a pattern and then make a reasonable conjecture for the next number in the sequence.

Answers

We will find the pattern as follows:

105 - 104 = 1

104 - 102 = 2

102 - 99 = 3

99 - 95 = 4

95 - 90 = 5

90 - 84 = 6

So, it is reasonable to assume that the next value will be 77.

Find the possible outcomes for each event in rolling a number die. Then find the probability of each event as a fraction, decimal and percent.

Answers

SOLUTION

Given the question in the image, the following are the solution steps to answer the question.

STEP 1: Write the formula for calculating probability

[tex]P(event)=\frac{number\text{ of favorable outcomes}}{number\text{ of possible outcomes}}[/tex]

STEP 2: State the number of possible outcomes

[tex]\begin{gathered} A\text{ die has 6 faces numbered 1,2,3,4,5,6} \\ Therefore,\text{ the number of possible outcomes will be 6} \end{gathered}[/tex]

STEP 3: Answer question A

Rolling a number less than 7

[tex]\begin{gathered} Numbers\text{ less than 7}\Rightarrow6,5,4,3,2,1 \\ n(numbers\text{ less than 7\rparen}\Rightarrow6 \\ \\ By\text{ substituting the values into the formula in step 1,} \\ P(Rolling\text{ a number less than 7\rparen}\Rightarrow\frac{6}{6}=1 \\ \\ Percentage\Rightarrow\frac{1}{1}\times100=100\% \end{gathered}[/tex]

Hence,

Possible outcomes are 6,5,4,3,2,1

Probability = 1

Probability = 1.0 as decimal

Probability = 100% as percentage

STEP 4: Answer Question B

Rolling an 8

[tex]\begin{gathered} Possible\text{ outcomes}\Rightarrow8 \\ n(8)\Rightarrow0 \\ Probability=\frac{0}{8}=0 \\ Percentage=0\times100\%=0\% \end{gathered}[/tex]

Hence,

Possible outcome is 0 since there is no face of the die having 8

Probability = 0

Probability = 0.0 as decimal

Probability = 0% as percentage

STEP 5: Answer Question C

Rolling a number greater than 4

[tex]\begin{gathered} Possible\text{ Outcomes}\Rightarrow5,6 \\ n(Possible\text{ outcomes\rparen}\Rightarrow2 \\ Probability=\frac{2}{6}=\frac{1}{3}\approx0.333 \\ Percentage=\frac{1}{3}\times100=\frac{100}{3}=33.33\% \end{gathered}[/tex]

Hence,

Possible outcomes are 5,6

Probability = 1/3

Probability = 0.333 as decimal

Probability = 33.33% as percentage

STEP 6: Answer Question D

Rolling a number other than 6

[tex]\begin{gathered} Possible\text{ outcomes}\Rightarrow1,2,3,4,5 \\ n(Possible\text{ outcomes\rparen}\Rightarrow5 \\ Probability=\frac{5}{6}=0.8333 \\ Percentage=\frac{5}{6}\times100=83.33\% \end{gathered}[/tex]

Hence,

Possible outcomes are 1,2,3,4,5

Probability = 5/6

Probability = 0.8333 as decimal

Probability = 83.33% as percentage

Josie sold 790 tickets to a local car show for a total of $4,390.00. A ticket for a Child costs $4.00 and adult ticket costs $7.00. How many of each ticket did she sell? A) Children’s ticket? B) Adult Ticket?

Answers

Let's define the following variables first.

A = number of tickets sold for adults

C = number of tickets sold for children

From the question, we can say that or form the following equations:

1. A + C = 790 tickets

2. $7A + $4C = $4, 390

The first equation can also be written as A = 790 - C. We can use this equation and replace "A" in the second equation.

[tex]7(790-C)+4c=4,390[/tex]

From that, we can solve "C" by solving the equation formed above.

[tex]\begin{gathered} \text{Distribute 7 to the terms inside the parenthesis.} \\ 7(790)-7(C)+4C=4,390 \\ 5,530-7C+4C=4,390 \\ \text{Subtract 5,530 on both sides of the equation.} \\ -7C+4C=-1140 \\ -3C=-1140 \\ \text{Divide -3 on both sides.} \\ C=380 \end{gathered}[/tex]

Therefore, 380 tickets for children were sold.

Since there are 790 tickets in total that are sold and 380 tickets for children were sold, we can say that 410 tickets for adult was sold.

[tex]\begin{gathered} A=790-C \\ A=790-380 \\ A=410 \end{gathered}[/tex]

Answer: x= 1.20833

The way it was written was a little confusing but hope this helps, This may be wrong just re write it for me and it should be correct next time.

Step-by-step explanation:

Step 1: Make parentheses

( 3x - 2 ) 4 ( -2x - 5 ) 3 = ( 1 + x ) 6

Step 2: Solve parentheses ( Multiplication and division first )

(4 * 3x = 12x) - (4 * 2 = 8) -> 12x - 8

(-2x * 3 = -6x) - (3 * 5 = 15) -> -6x - 15

(6 * 1 = 6) + (6 * x = 6x) -> 6 + 6x

New and improved equation:

-12x - 8 - 6x  - 15 = 6 + 6x

Step 3: add like terms

-12x - 6x = -18x

-8 - 15 = -23 so...

-18x - 23 = 6 + 6x

Step 4: solve it

-18x - 23 = 6 + 6x

               + 23

-18x = 29 + 6x

-6x

-24x = 29

x= 1.20833

It took Brian 3 hours to drive to a rock concert. On the way home, he was able to increase his average speed by 23 mph and make the return drive in only 2 hours. Find his average speed on the return drive.The equation from part 2 is 3x=2(x+23)Step 3 of 3: Solve the equation found in part 2 for x. Use this information to answer the given word problem.

Answers

Answer:

69 mph

Explanation:

The equation that represents this situation is:

[tex]3x=2(x+23)[/tex]

We are required to determine Brian's average speed on the return drive.

To do this, we first find the value of x.

[tex]\begin{gathered} \text{Open the bracket} \\ 3x=2x+46 \\ \text{Subtract 2x from both sides} \\ 3x-2x=46 \\ x=46\; \text{mph} \end{gathered}[/tex]

Using the value of x, we find the average speed on the return drive.

[tex]x+23=46+23=69\text{mph}[/tex]

Therefore, the average speed on the return drive will be 69 mph.

In triangle ABC measure of angle A equals 45°. The altitude divides the side AB into two parts of 20 and 21 units. Find BC.

Answers

In triangle  ABC, BC = 29 units.

Given,

In Δ ABC, ∠A = 45°.

A perpendicular line segment traced from a triangle's vertex to its opposite side is said to be the triangle's altitude.

Let altitude meet AB on D.

So, AD = 20 units and DB = 21 units and ∠ADC = ∠BDC = 90°

In ΔADC,

tan A = DC/AD

tan 45° = DC/20

          1 = DC/20

      DC = 20 units

In ΔBDC,

BC² = BD² + DC²     (Pythagorean Theorem)

      = 21²  + 20²

      = 441 + 400

      = 841

BC  = √841

      = 29  

Hence, BC = 29 units.

Answers

24 millennials will use blogs to make a purchase and 60 millennials will  never buy anything without reading a review first.

Here, we are given that 33% of millennials rely on blogs before making a purchase and eight out of 10 millennials never buy anything without reading a review first.

a. If there is a sample of 75 Millennials, out of these 33% will use blogs to make a purchase.

Thus,

33% of 75

= 33/100 × 75

= 33/4 × 3

= 99/4

= 24.75

Since, the number of millennials cannot be a decimal number, we approximate it to the lowest integer, that is, 24.

Thus, 24 millennials will use blogs to make a purchase.

b. Now, if there is a sample of 75 Millennials, out of these 8 out of 10 will never buy anything without reading a review first.

8 out of 10 in percentage terms will be-

8/10 × 100

= 80%

Thus,

80% of 75

= 80/100 × 75

= 80/4 × 3

= 20 × 3

If function f(x) = [tex]x^2[/tex] + 4x -1, then the value of g(x)= f(x+4) = [tex]x^2[/tex] + 12x +31

The function is

f(x) = [tex]x^2[/tex] + 4x -1

The function is the expression that represents the relationship between one variable and another variable. If one variable is dependent variable then the another variable is independent variable.

The value of g(x) = f(x+4)

First we have to find the value of f(x+4)

Substitute the values in the function

f(x) = [tex]x^2[/tex] + 4x -1

f(x+4) = [tex](x+4)^2[/tex] + 4(x+4) - 1

= [tex]x^2[/tex] + 8x +16 + 4x+16 - 1

Rearrange the terms and combine the like terms
