Step-by-step explanation:

Answer:

38.13 inch² (Approximately)

Step-by-step explanation:

The following figure has a Semicircle and a Rectangle.

The length of the Rectangle = 6 inches

The breadth of the Rectangle = 4 inches

Area of a Rectangle = Length * Breadth

= 6 * 4

= 24 inch²

Diameter of the Semicircle = 6 inches

Radius of the Semicircle = Diameter/2

= 6/2

= 3 inches

Area of a Semicircle = πr²/2

= 3.14 * 3²/2

= 3.14 * 3 * 3/2

= 3.14 * 9/2

= 1.57 * 9

= 14.13 inch² (Approximately)

Total area of the figure = Area of the rectangle + Area of the Semicircle

= 24 + 14.13

= 38.13 inch² (Approximately)

Answer: 21.4 pounds

Step-by-step explanation:

To calculate the amount of weight that is made up of body fat, you need to multiply the weight by the body fat percentage.

Weight of body fat = 162 pounds x 13.2% = 21.384 pounds

Then, round it to the nearest tenth which is, 21.4

Therefore, approximately 21.4 pounds of the individual's weight is made up of body fat.

Answer: 21.4 lb

Step-by-step explanation:

The question is asking how much weight consists of body fat.

We know that 13.2% of the total weight is body fat, and the total weight is 162 pounds.

Multiply to find out the body fat weight.

Percentage as a decimal over 1 * 162

0.132 * 162 = 21.384 lb

Round to nearest tenth: 21.4 lb

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.

Piper has $425.82 in her checking account. How much does she have in her account after she makes a deposit of $120.75 and a withdrawal of $185.90?

Answers

Answer: 360.67

Step-by-step explanation:

425.82 + 120.75 = 546.57

546.57 - 185.90 = 360.67

deposit = adding

withdrawal = subtraction

Answer:

$360.67

Step-by-step explanation:

Break it down:

Original: $425.82

Deposit: $120.75

Withdrawal: $185.90

What is a deposit?

A deposit is used in terms of money, and it's when you put money into your account/bank. We would use addition.

What is a withdrawal?

A withdrawal is also used in terms of money, and it's when you take money out. We would use subtraction.

Let's write an equation:

425.82+120.75

=546.57

546.57-185.90

=360.67

Piper will have $360.67 after her 2 transactions. Hope this helps! :)

Answer:

See below.

Step-by-step explanation:

a) $81235 - $15405 = $65830

1) The graph uses cubes to represent the amount of sales.

2) I wonder if the amount of sales is proportional to the length of the side of the cube or to the volume of the cube.

Using a ruler, the Year 1 cube has side length 5 units.

Using the same ruler, the Year 5 cube has side length 18 units.

The volume of the Year 5 cube is 5832 units³. The volume of the Year 1 cube is 125 units³.

The ratio of the volumes of Year 5 cube to the Year 1 cube is

5832/125 = 47:1

The ratio of sales of Year 5 to Year 1 is

81235/15405 = 5:1

The sales of Year 5 are approximately 5 times the sales of Year 1, tbut the cube of Year 5 has approximately 47 times the volume of the cube of Year 1. The graph is misleading because the volumes of the cubes are not proportional to the amounts of sales.

d) 47 times in volume

Answers

Answer: x=16 degrees

Step-by-step explanation:

Let's assume that angle (7x-2) is angle P, and angle (4x+6) is angle Q. The lines are parallel, so angle P is correspondent to Angle F, meaning that they are equal.

So we know that a straight line is 180 degrees, so we can form an equation like this: Angle F+ Angle Q= 180 degrees.

Now let's add in the information:

7x-2+4x+6= 180 degrees

11x+ 4= 180

11x= 180-4

11x = 176

x= 16 degrees

Total area = area of parallelogram + area of trapezoid

Answers

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

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

A circular pool has a radius of 6 ft. What is the approximate circumference of the pool?

A. 19 ft
B. 38 ft
C. 113 ft
D. 452 ft

Answers

Circumference = 2πr;
r = 6 ft. => C = 2π • 6 ≈ 37.7 ≈ 38 ft.
Answer: B 38 ft.

Answer: Option B. 38 ft

Step-by-step explanation:

To find the circumference of a circle, we use the formula C = 2πr, where C represents the circumference, r represents the radius of the circle, and π (pi) is a mathematical constant that is approximately equal to 3.14.

In this problem, we are given that the radius of the circular pool is 6 ft. We can substitute this value into the formula to find the circumference:

C = 2πr

C = 2π(6)

C ≈ 37.7 ft

Therefore, the approximate circumference of the pool is 37.7 feet. This is closest to answer choice B, which is 38 ft.

Odessa and Randall play a game in which the highest score wins. They record their scores and plot them on the dot plots, as shown.

Based on the data, which statement about Odessa's and Randall's scores is true?

A. Odessa is generally worse at the game than Randall because her median score is lower than Randall's median score.

B. Odessa is less consistent at the game than Randall because the variability of her scores is greater than the variability of Randall's scores.

C. Randall is generally better at the game than Odessa because his median score is higher than Odessa's median score.

D. Randall is more consistent at the game than Odessa because the variability of his scores is greater than the variability of Odessa's scores.

(I got confused on the answers because of some of the repeating words)

Answers

Answer: B. Odessa is less consistent at the game than Randall because the variability of her scores is greater than the variability of Randall's scores.

Step-by-step explanation: I summed up all of Randall's scores and got 410 and then I summed up all of Odessa's scores and got 660 so that means that Odessa's scores are bigger than Randall's scores.

The data on the dot plot shows that the B. Odessa is less consistent at the game than Randall because the variability of her scores is greater than the variability of Randall's scores.

What do the dot plots show ?

Odessa's scores are more spread out and less consistent than Randall's scores. This could be due to a number of reasons, such as differences in skill level, luck, or consistency in performance.

Overall, a greater degree of variability in Odessa's scores compared to Randall's scores suggests that Odessa's performance in the game is less predictable and consistent than Randall's performance.
