ASAP someone help; Assume people around a table could only reach 1.5m. Calculate the area that could be reached. Show your working

Answers

Answer 1

Answer: Given:
Circle radius = 2.75 m
People's reach = 1.5m

Get the area of the circle.
A = π r² ⇒ 3.14 * (2.75m)² ⇒ 3.14 * 7.5625m² = 23.75 m²

Get the area of the inner circle:
r = 2.75 m - 1.5 m = 1.25 m

A = 3.14 * (1.25m)² ⇒ 3.14 * 1.5625 m² = 4.91 m²

Subtract the area of the inner circle from the total area to get the area that people can reach.

A = 23.75 m² - 4.91 m² = 18.84 m²

The system of inequalities below describes the relationship between Cori’s age, C, and Livy’s age, L. DOK 2C + L > 43
C - 4L < 3

Which of the following could be the ages of Cory and Livy?
Livy could be 13 years old, and Cori could be 35 years old.
Livy could be 15 years old, and Cori could be 28 years old.
Livy could be 33 years old, and Cori Could be 10 years old.
Livy could be 20 years old, and Cori could be 85 years old.

Answers

Answer:

Livy could be 13 years old, and Cori could be 35 years old.

Step-by-step explanation:

Given : The system of inequalities describes the relationship between Cori’s age, C, and Livy’s age L.

C + L > 43

C - 4L < 3

We have to determine the ages of Cory and Livy.

We will plot both the inequality in a graph.

Thus, below attachment shows the graph of the two given inequality

Let x axis represent the Cori’s age, C, and y - axis Livy’s age L.

Now we plot the given ages in the graph and those points lies in intersection will given the ages of Cori and Livy.

Thus, Only (35 , 13) lies in the intersection,

We reject other points as the lies on dotted edges of graphs.

Thus, Livy could be 13 years old, and Cori could be 35 years old.

Answer:The system of inequalities below describes the relationship between Cori’s age, C, and Livy’s age, L.

C + L > 43

C - 4L < 3

Which of the following could be the ages of Cory and Livy?

Livy could be 33 years old, and Cori Could be 10 years old.

Livy could be 15 years old, and Cori could be 28 years old.

Livy could be 13 years old, and Cori could be 35 years old.

Livy could be 20 years old, and Cori could be 85 years old.

Step-by-step explanation:

use the commutative property to solve for n. 55,207+87,331=87,331+n= dont understand, please help

Answers

n equals 55,207 its like a repeat

Final answer:

The commutative property allows us to rearrange the terms within an addition operation without affecting the result. In this case, we use it to solve for 'n' in the equation, resulting in n=55,207.

Explanation:

The student is asked to use the commutative property of addition, which simply states that the order in which numbers are added does not affect the sum. Therefore, if we have the equation 55,207 + 87,331 = 87,331 + n, using the commutative property, we can rearrange the terms of the equation to solve for 'n'.

So, if we rewrite 55,207 + 87,331 = 87,331 + n as 55,207 = n (by subtracting 87,331 from each side), we get the value of n. Therefore, n = 55,207.

Hamid has gained weightHe now weighs 88kg, which is 10% higher than his normal weight.

What is Hamid's normal weight?

Answers

If we let x be Hamid's normal weight, 10% of the normal weight can be expressed as 0.10x. The equation that would let us better visualize the problem,
(1.10)x = 88

The value of x from the equation is 80.

Therefore, the answer is 80 kg.

The normal weight of Hamid is 80 kg.

Step-by-step explanation:

Given information:

The current weight of Hamid is 88 kg.

Let , $W$ is the normal weight of hamid.
