Answer:

r =2.9985yd

Step-by-step explanation:

Given that the circumference of a circle is 2 $\pi$ r

where r is the radius and $\pi$ = 3.1415926....

You have

2 $\pi$ r = 18.84 yd

2(3.1415926)r = 18.84 yd

6.2831r = 18.84yd

divide through by 6.2831

r = 2.9985yd = aprox 3yds

Bought three boxes totaling 151 book cost 50% more than the other two what was the price of the more expensive book 80 85 90 95

GenaCL600 [577]

Two cheaper books = x
more expensive = 1.5x
so, 2.5x=150
150/2.5=x=60
therefore the more expensive book = 90

Using a table of values, determine the solution to the equation below to the nearest fourth of a unit. 2^x=1-3^x

Greeley [361]

Answer:

Option (1)

Step-by-step explanation:

Given equation is,

$2^x=1-3^x$

To determine the solution of the equation we will substitute the values of 'x' given in the options,

Option (1)

For x = -0.75

$2^{-0.75}=1-3^{-0.75}$

0.59 = 1 - 0.44

0.59 = 0.56

Since, values on both the sides are approximately same.

Therefore, x = -0.75 will be the answer.

Option (2)

For x = -1.25

$2^{-1.25}=1-3^{-1.25}$

0.42 = 1 - 0.25

0.42 = 0.75

Which is not true.

Therefore, x = -1.25 is not the answer.

Option (3)

For x = 0.75

$2^{0.75}=1-3^{0.75}$

1.68 = 1 - 2.28

1.68 = -1.28

Which is not true.

Therefore, x = 0.75 is not the answer.

Option (4)

For x = 1.25

$2^{1.25}=1-3^{1.25}$

2.38 = 1 - 3.95

2.38 = -2.95

It's not true.

Therefore, x = 1.25 is not the answer.

HELP PLEASE ANSWER!! Tomika plans to run 84 miles in 4 weeks . If she continues the pattern,how many miles miles will she run in

Maurinko [17]

Answer:

She will run a distance of 1095.78 miles per year.

Number of days in a year = 365.25

Number of days in a week = 7

Number of weeks in a year = 365.25/7 = 52.18 weeks.

Tomika plans to run 84 miles in 4 weeks.

Distance run by Tomika in 1 week = 84/4 = 21 miles.

Distance run by Tomika in 1 year = 21*52.18 = 1095.78 miles

So she will run a distance of 1095.78 miles per year.

Solve the equation: X to the 4th power - 81=0

Musya8 [376]

$x^4-81=0\\
x^4=81\\
x^4=3^4 \vee x^4=(-3)^4\\x=3 \vee x=-3$
