Michael is making a card for his dad's birthday. He's shaded a triangular section on the card where he wants to write his dad a message. What is the area of the parts of the card that are not shaded?(sides are 12cm, 3,, 9 )

144
108
72
66

Answers

Answer 1

Answer:

Option c) 72 cm²

Step-by-step explanation:

In the figure attached we can see a rectangle ABCD with length 12 cm and width 9 cm.

A  triangle PEF with height BE and base EF.

Since side AE = 3 cm, so side EB = EC = 9 - 3 = 6cm

and EF = AD = 12 cm

Now we will find the area of of the parts of the card that are not shaded.

Area of parts that are not shaded = Area of rectangle - area of shaded triangle

= (12×9) - 1/2 (BE)(EF)

= 108 - 1/2(6)(12) = 108 - (3)(12) = 72

Option c) 72 cm² is the area of non shaded part.

If you divided 32 by 6 you get 5.3333 , if you do 324÷6 you will get 54 , and 44 divided by 6 you get 7.3333. 324 divided by 6 comes out to 54 a number without decimals so it’s 324.

Mr. Perry took his family out to
dinner last night and their subtotal
was $88.24. The sales tax was 5%
and he left a 20% tip. If Mr. Perry
put $120 on the table, how much
change did he receive?

[Show Work Please]

Answers

Answer: $8.83

Step-by-step explanation:

Facts:

Total before extra fees: $88.24

Sales tax: 5%

plus a 20% tip afterwards.

Gave $120

Change= ?

___________

Step 1: Add the sales tax

The first thing to do is find 5% of 88.24, since the sales tax was 5% of the cost of their dinner.

5% of 88.24= 4.41200---> $4.40

Now we add it to the subtotal.

4.40+ 88.24= $92.64

Step 2: Add the 20% tip.

Since the question puts the "20% tip" statement  after the 5% tax, I'm going to assume that the 20% tip is 20% of the dinner cost after the tax was added.

So the new cost is 92.64. All you need to do is find 20% of 92.64, and then add the result to 92.64. Look:

20% of 92.64= 18.528--> $18.53

18.53+92.64= $111.17

Now, there we have the total cost of dinner.

Step 3: Find how much change he got.

So now we know the total cost is $111.17, and that he paid with $120. He obviously  paid more than the total cost, so to find the amount of change, simply subtract the 111.17 from 120:

120-111.17= $8.83

He recieved $8.83 in change because he paid $8.83 more than the expected balance (actual total cost).

Hope this helps :)) Also brainliest would be appreciated, i worked pretty hard on this :)

Answer:$8.82 Change

Step-by-step explanation:

88.24*1.20=105.89. 105.89*1.05=111.18

$120-$111.18=$8.82 change.

We have been given a number 5.78. We are asked to choose the correct statement which shows that 5.78 is a rational number.

Upon looking at our given choices, we can see that only option A is the correct choice as it has repeating digits (78) after decimal.

We know that a number with repeating decimals can be written as a fraction, therefore, option D is the correct choice.

which is faster: drive a car at a rate of 40 kilometers per hour or drive a car at a rate of 15 meters per second

Answers

Answer:

Step-by-step explanation:

Let's convert one of these measurements so that both measurements have the same units.  15 m/sec is equivalent to 0.015 km/sec, which in turn is equivalent to

0.015     km      3600 sec  

--------- --------  ----------------- = 54 km/hr

    1        sec       1 hr

This latter result (54 km/hr) is faster than (40 km/hr).

15 meters per second is equivalent to 54 kilometres per hour.

The answer is D, or (2, -2).

Explanation: The angles that would make up the top left and right corners of the parallelogram would be (4,0) and (2,0). Because (0, -2) is the bottom left angle, to make this shape a full parallelogram, the y-coordinate of the other angle would have to also be -2, and it would have to be to the right of the origin so the figure does not look sloppy. To add on to this, none of the given x-coordinates are negative, so the fourth point should not have a negative x-coordinate. That would instantly get rid of A, B, and C. Therefore, your answer would be D, or (0, -2).

Answers

Answer:

4 miles per hour

Step-by-step explanation:

Unit rate is the rate of something per 1 unit. In other words, the unit rate is x units per 1 unit. In this situation, the unit rate is how many miles Hassan walks in 1 hour.

Proportion

First, to find the rate of anything we can set up a proportion. In the question, the rate is described as miles per hour, so the miles will be the numerator and the hours will be the denominator.

This creates the proportion [tex]\frac{12miles}{3hours}[/tex]

So, the rate we are given is 12/3.

Unit Rate

To find the unit rate we need to make the denominator equal to 1. To do this, divide both the numerator and denominator by 3.

12/3 equals 43/3 equals 1

So, this means that the new proportion is 4/1. Next, we can add our units, which means that Hassan walks 4 miles per 1 hour.

Graph

Now we can resize the bar graph. The purple bar should be set to 4 because this represents the miles. Then, the green bar should be set to 1 because it represents the hours.

4 miles per hour bc that's what the answer is

Answer:

The fundamental counting principle is used to count the total number of possible outcomes that are in a situation.

What does the fundamental counting principle state?

The fundamental counting principle states that if there are n ways of doing something, as well as m ways of doing another thing, then there are n×m ways to perform both of these actions.

The Fundamental Counting Principle helps when determining the sample space of probability as it figures out the total number of ways the combination of events can occur. Therefore, it is used as a guide when determining the sample space of a probability.

Lastly, the limitation is that the Fundamental Counting Principle is that it assumes that each basic event is equally probable, which does not necessarily have to be true.

Show and explain how replacing one equation by the sum of that equation and a multiple of the other produces a system with the same solutions as the one shown.8x + 7y = 394x 14y = 68Answer: Sample Response: Using the linear combination method, you can multiply the first equation by 2 and add the equations to get 20x = 10. Dividing both sides by 20, x = 1/2. To solve for y, substitute 1/2 for x in the equation 8x + 7y = 39 to get 4 + 7y = 39. Solving this equation, y = 5. Checking this in the other equation, 4(1/2) 14(5) = 68 results in 2 70 = 68 or 68 = 68. The solution of the system shown is (1/2, 5). The system 8x + 7y = 39 and 20x = 10 is formed by replacing 4x 14y = 68 by a sum of it and a multiple of 8x + 7y = 39. Since 20(1/2) = 10, the system 8x + 7y = 39 and 20x = 10 also has a solution of (1/2, 5). Royale has been undeclared as a national park and has been purchased by a large resort.
