Question 7!!

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

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! :)

theta is a right angled triangle tan theta=24/43) work out the value of theta give your answer to 1 decimal place

Answers

Answer:

We know that tan(theta) = opposite/hypotenuse = 24/43.Using inverse tangent, we can find the angle theta:theta = tan^(-1)(24/43)Using a calculator, we can find:theta ≈ 29.6 degrees (rounded to 1 decimal place)Therefore, the value of theta to 1 decimal place is approximately 29.6 degrees.

Step-by-step explanation:

Final answer:

The value of theta in a right angle triangle for which tan(theta) = 24/43 can be found using the inverse tangent function, also known as arctan. When evaluated, theta equals approximately 29.4 degrees.

Explanation:

In trigonometry, the tangent of an angle in a right angle triangle is the ratio of the side opposite to the angle to the side adjacent to the angle. Here, tan(theta) = 24/43, which means the ratio of the opposite side to the adjacent side is 24/43. To find the angle 'theta', you will need to use the inverse tangent function, commonly known as arctan or tan^-1.

In this case, theta = arctan(24/43). Use a calculator and ensure it's set to give the answer in degrees, not radians. The answer would be approximately 29.4 degrees to 1 decimal place.

Need help asap will give decent points

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.

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

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

Adam is purchasing a new television that costs $2,187.96 after tax. He borrowed the money from his parents and must pay back the full amount plus simple interest at the rate of 3.5%. What is the total amount he will pay if he takes 2 years to pay his parents back? (Include Decimal with the cents; No Commas)

Answers

He will pay 2264.54 with 3.5% interest

It is determined that he will pay an interest of $153.16 using simple interest and taking the exercise's specified criteria into account.
Basic Interest
When there is only one compounding every time period, simple interest is applied.
The formula for calculating interest after t years is 1 = Prt.
Where P is the initial sum and r is the interest rate in decimal form.
The following are the parameters for this problem:
P = 2187.96, r = 0.035, t = 2.
The interest will therefore be paid at the rate of 1=Prt = 2187.96 x 0.035 2 = $153.16.
