The composite figure is made up of three simpler shapes. What is the area of the figure?

A. 80
B. 49
C. 68
D. 74

Answers

Answer: I’m pretty sure it’s 80

Step-by-step explanation:

Because the very top triangle is 4x3 which is 12 then the rectangle under it is 6x3 which is 18 then the triangle under that is 5x3 which is 15 and the triangle on the left is also 15 and the square in the middle is 4x5 which is 20 and add it all up 12+18+15+15+20=80 sry if that’s confusing.

Answer:

74 is the answer

Step-by-step explanation: You should find the area of each shape and add all the areas together to get the full area of the shape.

(base x height)+(length x breath)+(1/2 x base x height)
(10x5)+(6x3)+(1/2x3x4)

50+18+6

74 ← this is the full area of the shape

and, remember when finding the area of a triangle you should always multiply 1/2 too for example- ( 1/2 x base x height )

Renee hiked for 7 3/4 miles. After resting, Renee hiked back along the same route for 6 1/4 miles. How many more miles does Renee need to hike to return to the place where she started? Represent your answer as a simplified mixed number, if necessary.

Answers

Answer:

Renee will need to hike 1 1/2 more miles.

Step-by-step explanation:

If she hiked to her spot of 7 3/4 miles, she would need to hike another

7 3/4 more miles back. So, if she has hiked back 6 1/4 miles so far, you would subtract 7 3/4 - 6 1/4 to get 1 1/2 more miles!

Hope this answer and explanation helps you!

The verticals of a triangle are (2,5) (1,2) (3,1) to see once reflect the triangle in the x-axis and then rotate the triangle 90 degrees counterclockwise about the origin. what are the coordinates of the image.

Answers

Answer:

(5,2) (2,1) (1,3)

Step-by-step explanation:

First, reflect the image over the x-axis. This affects the y of each point to become negative, and moves the triangle from quadrant I to quadrant IV. This changes the points to be (2,-5) (1,-2) (3,-1).

Next, when rotating the triangle counterclockwise about the origin, the easiest way to describe what this does to the points is that it switches the numbers for x and y, and makes all of them positive. This is because the rotation ends up moving the coordinates back into quadrant I, so they're positive. However, the rotation does switch up the points a bit. So now, the points are (5,2) (2,1) (1,3).

Answer: are (5,2) (2,1) (1,3).

Ahat is the area of this quadrilateral?

Answers

Answer:

A. 12 square feet

Step-by-step explanation:

So it's easier to find the area when you split the shape into 2 parts, and they already did that for you. So basically you find the area of both triangles and add them together. The formula for a triangle is base x height divided by 2. You don't have to do that because there are 2 triangles with the same base and height so you don't have to divide it by 2. 3 x 4 = 12, so A. 12 square feet is your answer.

the answer is A.) 12 square feet

The markup percentage regarding the sale of the good will be 136%.

How to calculate the percentage?

From the information given, the initial cost is $55.00 and the new price is $130.19. The increase in percentage will be:

= (130.19 - 55)/55 × 100

= 75.19/55 × 100

= 136%

Therefore, the markup percentage regarding the sale of the good will be 136%.

The Smith family went to eat at Buffalo Wild Wings. The bill was $43.86. They gave the server a 20% tip. How much did they pay altogether?

Answers

Answer:

$52.63

Step-by-step explanation:

To find 20% of $43.86 we multiply $43.86 by 0.2

$43.86 • 0.2 = $8.772

Now add $43.86 and $8.772 to find out how much the family paid altogether.

$43.86 + $8.772 = $52.632

In money the smallest place value is cents so we have to round to the hundredths place.

Doing this we get the grand answer of:

$52.63

52.63

To find the altogether cost of the meal including tip you need to multiply the bill ($43.86) by 1.20

43.86(1.2) = 52.632

Same would go for if you were leaving a 10% tip but you would multiply by 1.10

1) If y is the amount of dog food in the bin, and x is the number of days the dogs have been fed, write an equation to represent the amount of food left in the old dog's bin.

You are pet sitting your neighbor's dogs for a couple of weeks. Each dog must be fed a different type of food. The instructions say to feed the old dog 2/3 pound of food each day from the bin with 25 lbs of kibble in it. The puppy is to get 1/4 pound of food each day from the bag with 20 lbs of puppy kibble in it. Use your system of equations to calculate the number of days until both containers have the same weight of food in them.

2)If y is the amount of dog food in the bin, and x is the number of days the dogs have been fed, write an equation to represent the amount of food left in the puppy's bin.

3)Use your equations to solve to find the number of days when both containers will have the same weight of food in them. (check your solution!)

Answers

The equation computed shows that the number of days until both containers have the same weight of food in them will be 12 days.

How to calculate the equations?

From the information given, the instructions say to feed the old dog 2/3 pound of food each day from the bin with 25 lbs of kibble in it. the equation will be:

= 25 + 2/3d

= 25 + 0.67d

Also, the puppy is to get 1/4 pound of food each day from the bag with 20 lbs of puppy kibble in it. This will be:

= 20 + 1/4d

= 20 + 0.25d

The number of days until both containers have the same weight of food in them will be:

25 + 0.67d = 20 + 0.25d

0.67d - 0.25d = 20 - 25

0.42d = 5

d = 5/0.42

d = 11.9

d = 12 days

The lowest common multiple is 60 as it is the first multiple the two have in common.
