A) What is the radius of a circle that has an approximate circumference of 81.64 meters?

1 answer:

8 0

For B, the equation for circumference is pi multiplied by diameter. So, 10 * 2 = 20, and 20*3.14 is 62.8 cm

For C, assuming that "approximate" means that they used 3.14 for pi, then 81.64 / 3.14 = 26, and 26 / 2 = 13 cm

HELP ME PLEASE True or false: z=−5 is a solution to the inequality −2|z−3|<−20.

Dovator [93]

your question: 

True or false: z=−5 is a solution to the inequality −2|z−3|<−20.

answer: 

-2|z-3|<-20

-------. -----

-2 -2

|z-3|<10

equation 1: equation 2:

z-3<10. z-3>-10

z<13 z>-13

So false, z=-5 is not a solution to the inequality.

hope this helps, have a great day! :)

1. The sides of a triangle have lengths of 5, 8, and 6.(1/ 2). An angle bisector meets the side of length 6.(1/ 2). Find the len

Advocard [28]

Answer:

Step-by-step explanation:

i assume x+y=6(1/2)=\frac{13}{2}

$\frac{5}{8}=\frac{x}{y}=\frac{x}{\frac{13}{2}-x}=\frac{2x}{13-2x}\\65-10x=16x \\26 x=65\\2x=5\\x=\frac{5}{2}\\y=\frac{13}{2}-\frac{5}{2}=\frac{8}{2}=4$

In the parallelogram below, AB=2x+8 and CD=5x-1. What is the length of AB?

pshichka [43]

Answer:

AB = CD

BC = DA

Step-by-step explanation:

Since 3x+2 = 5x-2, solving for x yields 2. Since BC = 4x+1 = DA, BC and DA both equal 4(2)+1 = 9.

Suppose that your net income for the month is 1500 and that your total expenses are 2500 which statement is accurate?

mestny [16]

C. you have a deficit of 1000

Explanation:

We say that we have a surplus when the net income is more than the total expenses, while we say that we have a deficit when the net income is less than the total expenses.

In this case, the net income is 1500, which is less than the total expenses (2500): so, we have a deficit. In order to calculate the deficit, we can use the formula

deficit = total expenses - net income

Substituting the data of the problem, we find

deficit = 2500 - 1500 = 1000
