Kelsey has designed the pendant shown, that hangs from a chain. She makes pendants by bending silver wire into circles. The desi

gn connects one circle made from a wire 6 cm long to a second circle made from a wire 8 cm long. She plans to sell the pendants at a craft fair, and her goal is to make a minimum profit of $50 at the fair. Part A The height of the pendant is determined by using the formula for the circumference of a circle, C = id. Find the total height of the pendant design from top to bottom in terms of it. Then find the height rounded to the nearest tenth of a centimeter. Use 3.14 for T.​

Answer:

<h2>4.4cm</h2>

Step-by-step explanation:

in this problem we are expected to solve for the diameter of each circle pendant and add them to get the height of the complete pendant.

we know that the circumference is given as

C=πd

for the small circle

C=6cm

6=3.142d

d=6/3.142

d=1.9cm

for the big circle

C=8cm

8=3.142d

d=8/3.142

d=2.5cm

the height then is 1.9+2.5=4.4cm

Lines M and N are parallel. Find the value of x.
AVprozaik [17]

Answer: 42

Step-by-step explanation:

First of all, referencing the data given, lines M and N are definitely <u>not</u> parallel, and intersect.

However, considering the system included in the question, you may solve for x in a plethora of ways, assuming both expressions are complete, and equal to f(x).

4x - 24 = y

3x + 18 = y

Using the elimination method, consolidate these equations into:

x - 42 = 0

x = 42

Hope it helps :) and post a more complete question if this isn't the answer you were looking for.

What is the square root of 61 to the nearest integer?
Gwar [14]

<span>We can calculate the nearest integer of the square root by estimation. </span>

<span>We know that 6*6=36, 7*7=49, 8*8=64, 9*9=72,</span>

<span>So 61 is nearest to 64 and acccording this the square root of 61 to the nearest integer is 8.

When filling out the 2000 Census, people could choose one of four options to describe their marital status. Data from the 2000 C
galben [10]

Answer:

0.098

Step-by-step explanation:

Given that when filling out the 2000 Census, people could choose one of four options to describe their marital status.

Data from the 2000 Census were used to compute the following probabilities

Marital status Never married Married widowed Divorced total

Prob           0.239          0.595      0.068     0.098 1

Actually we were not given probability for divorced but using total probability =1 we arrived at the probability for divorced as

1-sum of the remaining probabilities

=1-0.239-0.535-0.068\\=0.098

the probability that a randomly selected U.S. adult is divorced

= 0.098
