Question 7!!!

Total area= area of parallelogram + area of trapezoid

Answers

The total area of the figure is 52 square feet by adding the areas of the parallelogram and trapezoid

Calculating the total area

from the question, we have the following parameters that can be used in our computation:

parallelogram and trapezoid

Wher we have

Area of parallelogram = 7 * (6 - 2)

Area of parallelogram = 28

Also, we have

Area of trapezoid = 1/2 * (7 + 5) * 4

Area of trapezoid = 24

So, we have

total area = 28 + 24

total area = 52

Hence, the total area is 52 square feet

Part A - This question is saying that an item is priced at $25, without any discounts or usage of coupons, but David bought the item with a discount of 45%.

Part B - 45% of 25 is 11.25, meaning that the price David bought the item at was $11.25. Hope that helps!

Answer: $13.75

Step-by-step explanation:

A discount of 45% off = 100% - 45% = 55% of original price

Multiply the percentage by the regular price.

0.55 * 25 = 13.75

Answer: $88

Step-by-step explanation:

1. Plug in the given data into the formula.

p = 80

r = 0.1 (represents 10%)

t = 1 year

2. Solve for i based on the formula's values

i = (80)(0.1)(1) = 8

Interest earned is $8 but THIS IS NOT THE FINAL ANSWER!

3. Add i (interest) to p (starting amount)

Elena started with $80, so the interest of $8 is added for a final answer of $88 after one year.

A 25-foot magazine rack begins 20 feet south of the checkout desk and continues south. What are the coordinates of the beginning and end of the magazine rack? Explain or show how you got your answer. ANSWER CORRECTLY WITH AN EXPLANATION

Answers

Answer: The coordinates of the beginning of the magazine rack are (0,-20), and the coordinates of the end of the magazine rack are (0,-45).

Explanation:

The magazine rack begins 20 feet south of the checkout desk, so its starting point is 20 feet below the x-axis. This gives us the coordinates (0,-20) for the beginning of the rack. Since the rack is 25 feet long, it extends 25 feet to the south of its starting point. Therefore, the endpoint of the rack is 20 feet (the starting point) minus 25 feet (the length of the rack), or -5 feet south of the checkout desk. This gives us the coordinates (0,-45) for the end of the rack.

Brainliest?

The given information tells us that the magazine rack begins 20 feet south of the checkout desk and continues south for a length of 25 feet. Since the magazine rack is only moving in the south direction, we can say that the x-coordinate (horizontal distance) of both points will be the same.

Let's assign the x-coordinate of the checkout desk as 0. Then, the x-coordinate of the beginning and end of the magazine rack will also be 0.

The y-coordinate of the beginning of the magazine rack is 20 feet south of the checkout desk, which means it is 20 feet less than the y-coordinate of the checkout desk. If we assume that the y-coordinate of the checkout desk is y = 0, then the y-coordinate of the beginning of the magazine rack is y = -20.

To find the y-coordinate of the end of the magazine rack, we add the length of the rack (25 feet) to the y-coordinate of the beginning of the rack (-20 feet). This gives us y = 5.

Therefore, the coordinates of the beginning of the magazine rack are (0,-20) and the coordinates of the end of the magazine rack are (0,5).

1/8

Step-by-step explanation:1)there are 4 kings in a deck so the probability of not getting them is 1-(the probability of getting them)=1-(4/52)=12/13

2)there are heads and tails so the P of getting ont of them is half=1/2

4)there are 4 suits in a deck so 52/4=13; therefore, there are 13 hearts in the deck so 13/52=1/4

5)and means multiplication, so flipping heads*drawing a heart= question 2* question 4 =1/2 * 1/4=1/8

3) its a little complicated so you can consider it as the last option possible and choose, anyways "or" means addition so add the two probabilities to get 5/8

Answers

Answer:

Step-by-step explanation:

Josh has a total of banknotes and coins as 59 in his savings.

A method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

Since Unitary method is a technique by which we find the value of a single unit from the value and the value of more than one unit from the value of a single unit.

We are given that Josh has 52 euros saved.

In his savings, we can see that he only has banknotes of 5 euros and coins of 2 euros.

Therefore, 52 euros he have

Then 52 + 5 notes + 2 coins

= 59

2. The area of the trapezoid is 3, 584. 88 centimeters square

3. Area = 468, 975 ft²

4. Area = 3682. 04 m²

5. 94, 386. 93 mi²

How to determine the area

The formula used for calculating the area of a trapezoid is expressed as;

A = 1/2h( a + b)

Such that the parameters are given as;

A is the area of the trapezoidh is the height of the trapezoida and b are the side lengths

Substitute the values, we have;

Area = 1/2 × 23. 4(61. 2 × 92)

multiply the values

Area = 1/2 × 23.4(153.2)

multiply the values

Area = 1/2(3584. 88)

Now, divide the values, we get;

Area = 3, 584. 88 centimeters square

3. Area = 1/2 × 555 (463 + 1227)

Add the values

Area = 1/2 × 555(1690)

multiply the values

Area = 468, 975 ft²

4. Area = 1/2 × 63 × (41. 56 + 75.33)

add the values

Area = 1/2 × 63 × (116. 89)

multiply the values

Area = 3682. 04 m²

5. Area = 1/2 × 306. 7 (206. 6 + 408. 9)

Answers

Answer:

The first yes, the second no.

Step-by-step explanation:

Proportional means they follow a constant proportion. In the first example, 1 hr is 4.5 ft, so the constant is 4.5, which means that everything in the top line multiplied by 4.5 should equal the bottom line. 2*4.5=9, 3*4.5=13.5, if you check it it all works out. But on the second problem, 2 hrs is 20 ft, which means that the constant should be 10, because 2/2 is 1 and 20/2 is 10, but 4*10 does not equal 30, it equals 40, so right off the bat we know it’s not proportional.
