Your Assignment

Jason and Adam are using a kit to build their own electronics board for a computer project. They use a scale drawing included in the instructions to help build the board.

Jason will use the scale factor to find the board's actual length and width, then multiply those dimensions to find the board's area.

Adam says he knows another way.


Answer the questions to show how Adam could find the area of the scale drawing, and then use this strategy to find the area of the electronics board.

1. What is the area of the board shown on the scale drawing? Explain how you found the area.


Write your answer in the space below.















2. How can Adam use the scale factor to find the area of the actual electronics board? Remember, he uses a different method than Jason.

Step-by-step explanation:

There are 8 outcomes if a coin is flipped 3 times.

Of these, 4 start with tails.

Since 4 is the denominator here, C (3/8) is out.

Also 4 doesn't have 3 as a factor, so B (1/3) is also out.

After the tails flip, two heads follow.

That's one of four of the combinations starting with tails (THH, THT, TTH, TTT, so D is out, leaving A as our answer! (We would need two for A to work)

4 weeks. Find the ratio of the first​ movie's filming time to the second​ movie's filming time. Compare in weeks.

Answers

Answer:

26 /33

Step-by-step explanation:

Given that :

Number of days taken filming first movie = 45 1/2

Number of weeks spent filming second movie = 8 1/4

Concerning days to weeks ;

45 1/2 days = 91/2 days = 91/2 ÷ 7 ;

91 / 2* 1/7 = 91/14 = 6. 5 weeks

Hence,

Ratio of first week fuming to second week filming ;

6.5 weeks : 8 1/4 weeks

6 1/2 : 8 1/4

Hey there!

Do you remember what the Distributive property states? If not, no worries! Here's what this property states:

a(b+c)=ab+ac

In this formula, a, b, and c can be

Constants. These are numbers like 1, 2, 3, or -1, -2, -3... or even fractions, decimals... (all real numbers)Variables. These are letters like d, a, s, e, t, k, a...Variables can have a number next to them; it's called a coefficient.

Now that we know what this property states, let's simplify this expression.

5(x-2)

First, multiply 5 times x:

5x (5 is the coefficient of x, by the way)

Then, multiply 5 times -2 (please pay attention to the sign) :)

-10

Put both terms together.

Hence, the simplified expression is

[tex]\boxed{\boxed{\bold{5x-10}}}[/tex]

Is it possible to simplify the expression any further? No.

Why? Because 5x and -10 aren't like terms, so we cannot combine them.

Hope everything is clear.

Let me know if you have any questions!

x<15, probably

Step-by-step explanation:

maybe multiply 2 to each side to eliminate the fraction. so 3x+15<60. subtract 15 to isolate the variable term so 3x<45. divide by 3 to isolate x so x<15. check the work. is the inequality true for all values of x less than 15? let's try the first possible integer value, 14, to be sure. 3(14)+15= 57. so 57/2<30. now 57/2 is 28.5 and 28.5<30 so it seems right

question:find the angle measure of the missing angle

if you can pls explain ​

Answers

Answer:

85°

Step-by-step explanation:

So in geometry, the formula to find the sum of all interior angles is denoted as follows:

n = number of sides in the polygon

( n - 2 ) × 180° = sum of the interior angles

Using that formula, a triangle has 3 sides, so

n = 3 , therefore:

= ( 3 - 2 ) × 180°

= 1 × 180°

= 180°

Since the total sum of the interior angles of a triangle all have to add up to 180°, you can create the following equation and solve:

34° + 61° + x = 180°

Solve for x.

Answers

Answer:

(9/2, 4/3) or just x = 9/2, y = 4/3. (it's the same thing)

Step-by-step explanation:

First, multiply the first equation 2x + 3y = 13 by 2, so that you get 4x + 6y = 26. Now you have the same coefficient for y. Now, subtract the second equation 6y = 8 (i simplified it first) from the first one that is doubled. After that, you would have just one equation, 4x = 18. So x = 18/4 = 9/2. Substitute x to solve for y, and you'd get 4/3.

Answer:

  (x, y) = (-6, 8 1/3)

Step-by-step explanation:

The system of equations appears to be ...

2x +3y = 136x +6y = 14

Dividing the first equation by 2 gives ...

  3x +3y = 7

Subtracting the first equation from this, we get ...

  (3x +3y) -(2x +3y) = (7) -(13)

  x = -6

Then substituting for x in the first equation, we have ...

  2(-6) +3y = 13

  3y = 25 . . . . . . . . add 12

  y = 25/3 = 8 1/3 . . . . divide by 3

The solution is (x, y) = (-6, 8 1/3).

4. Calculate the expected value for the spinner at right?
(3pts)
8
1200
24
6

Answers

Answer: The expected value is 12.44

Step-by-step explanation:

The expected value can be calculated as:

EV = ∑xₙ*pₙ

Where xₙ is the n-th outcome. For the case of the spinner we have 3 possible outcomes:

x₁ = 8

x₂ = 6

x₃ = 24

And pₙ is the probability of the n-th event.

For the case of the spinner, the probability of each section will be equal to the quotient between the degrees of each arc, and the total number of degrees in a circle (360°).

First, we can see that for outcome = 8, the angle is a right angle, then it is equal to 90°, then the probability of this event will be:

p₁ = 90°/360° = 0.25

For outcome = 24, we have an angle of 120°, then the probability for this event is:

p₃ = (120°/360°) = 0.33

And the angle for the third arc must be such that:

90° + 120° + A = 360°

then:

A = 360° - 90° - 120° = 150°

Then the probability for the outcome = 6 is:

p₂ = (150°/360°) = 0.42

Now we can find the expected value as:

EV = (8*0.25 + 6*0.42 + 24*0.33) = 12.44
