The circumference of a circular island is 34.54 miles. What is the area of the
island?
Answer:
A = 94.99
Step-by-step explanation:
C = 2(3.14)r
34.54 = 2(3.14)r
34.54 = 6.28r
r = 34.54/6.28
r = 5.5
A = (3.14)r²
A = (3.14)5.5²
A = (3.14)30.25
A = 94.985
Answer:
95miles²
Step-by-step explanation:
The circumference of a circular island = 34.54 miles.
2πr=34.54miles
πr=17.27mile
r=17.27/πmile
the area of the island=πr²=π×{17.27/π}²=95miles² approx

Answer:
3 4/5
Step-by-step explanation:
7 3/10 - 3 9/10=
In this case 3/10 - 9/10 is cannot be so we have to borrow 1 whole from 7
so, 7 3/10 will become 7 3/10 + 1 or to add we have to change 1 as 10/10, any way 1 and 10/10 is equal but in this case we will use 10/10 to add 1 whole to 3/10 and minus 1 whole to 7
so, 3/10 + 10/10 = 13/10
and 7 - 1 = 6
so, 7 3/10 as 6 13/10
any way 7 3/10 and 6 13/10 is equal but, in this case we have to use 6 13/10 to minus, because 7 3/10 is cannot be
so, 6 13/10 - 3 9/10 =
=3 4/10 or 3 2/5

The Smith family went out for pizza. Their bill was $37.85. They left a tip of 15%. What was the approximate amount of the tip? pls help me!
Answer:
$5.7
Step-by-step explanation:
Given data
Bill= $37.85
Tip= 15%
Required
The amount of the tip
let us find 15% of $37.85
=15/100*37.85
=0.15*37.85
=$5.6775
Hence the amount of the tip is
=$5.7

Step-by-step explanation:
Following are weights, in pounds, of two-month-old baby girls. It is reasonable to assume that the population is approximately normal.
12.32 11.87 12.34 11.48 12.66
8.51 14.13 12.95 9.34 8.63
Required:
a. Construct a interval for the mean weight of two-month-old baby girls.
b. According to the National Health Statistics Reports, the mean weight of two—month-old baby boys is 13.9 pounds. Based on the confidence interval, is it reasonable to believe that the mean weight of two-month—old baby girls may be the same as that of two-month-old baby boys? Explain.
Answer:
10.224 < μ < 12.622 ;
Since the mean weight of 2-montj old baby boys (13.9) falls outside the confidence interval, we can conclude that it is not reasonable to believe that the mean weight of two-month-old baby girls may be the same as that of two-month-old baby boys.
Step-by-step explanation:
The confidence interval is given as :
Mean ± Margin of Error
margin of error = Zcritical * standard deviation /sqrt(n)
n = sample size
From the data:
12.32, 11.87, 12.34, 11.48, 12.66, 8.51, 14.13, 12.95, 9.34, 8.63
From the data:
Using calculator :
Mean, = 11.423
Standard deviation, s = 1.934
Zcritical at 95% confidence interval = 1.96
Sample size, n = 10
Margin of Error = 1.96* 1.934/sqrt(10) = 1.199
Lower boundary = 11.423 - 1.199 = 10.224
Upper boundary = 11.423 + 1.199 = 12.622
10.224 < μ < 12.622
Since the mean weight of 2-montj old baby boys (13.9) falls outside the confidence interval, we can conclude that it is not reasonable to believe that the mean weight of two-month-old baby girls may be the same as that of two-month-old baby boys.
If x = 5, then which of the following equations makes a true statement?
Which data set is the most spread from its mean? 0 14, 26, 24, 28 022, 16, 18, 36 O 22, 28, 20, 22 021, 19, 27, 25
Answer:
22, 16, 18, 36
Step-by-step explanation:
the mean of the data set is 23 and the number 36 is 13 digits away from that therefore this data set is the most spread out.
have a great day :D

Answer:
4744 ftStep-by-step explanation:
Consider the angle of depression is same as the angle between horizontal line on the ground and the direct line from the plane to the airport (alternate interior angles).
Use tangent to find the missing length.
tan = opposite / adjacent
tan 34° = 3200 / xx = 3200 / tan 34°x = 4744The distance is 4744 ft

A water balloon was launched into the top of the hill 38 feet above the ground
Answer: -71.104 ft/sec
Step-by-step explanation:So you need to know how fast the balloon is moving when it hits this person's head. velocity is based on time. So you need the time that it hits this person's head. You can get time from the position equation. Because the balloon hits this person's head 6 feet from the ground, you know that the final position is at 6 so you plug that into the position equation and solve for t. You look and see what the appropriate t value is and plug it into the velocity equation and see what the answer is.
6=-16t^2+40t+60
0=-16t^2+40t+54
plug in those values into the quadratic formula or your calculator and you get:
t = -.972
or
t = 3.472
since you can't have negative time, the other answer must be it.
So you then plug it in and solve.
v(3.472) = -32(3.472) + 40
which is approximately -71.104 ft/sec
or if they just want speed, 71.104 ft/sec. (remember, speed is velocity without direction)

c. Debbie and Jan are both in the 28% tax bracket. Since the interest is deductible, how much would Debbie and Jan each save in taxes? (Round your answers to the nearest cent.)
Step-by-step explanation:
Let's assume Debbie paid $1700 in interest, while Jan paid $9000.
Debbie Saves = $1700* 0.28
Jan Saves = $9000 * 0.28
Debbie Saves $476 in taxes
Jan Saves $2520 in taxes

Nancy: 30 -t < 18
Jamal: 12

Answer:
Jamal's inequality is correct
Step-by-step explanation:
Given
[tex]Sets:\{0,1,3,4,6,12\}[/tex]
Gary: [tex]6>0.5t[/tex]
Nancy: [tex]30 -t \le 18[/tex]
Jamal: [tex]12 \le t+12[/tex]
Required
Which of the inequalities is/are true
Gary: [tex]6>0.5t[/tex]
[tex]6>0.5t[/tex]
Divide both sides by 0.5
[tex]\frac{6}{0.5} > \frac{0.5t}{0.5}[/tex]
[tex]12 > t[/tex]
Rewrite as:
[tex]t < 12[/tex]
Gary's inequality is false because: [tex]12 = 12[/tex]
Nancy: [tex]30 -t \le 18[/tex]
[tex]30 -t \le 18[/tex]
Collect like terms
[tex]-t \le 18 - 30[/tex]
[tex]-t \le -12[/tex]
Divide both sides by -1
[tex]t \ge 12[/tex]
Nancy's inequality is incorrect because: 0,1,3,4 and 6 are less than 12
Jamal: [tex]12 \le t+12[/tex]
[tex]12 \le t+12[/tex]
[tex]12 - 12 \le t[/tex]
[tex]0 \le t[/tex]
Rewrite as:
[tex]t \ge 0[/tex]
Jamal's inequality is correct because: 0,1,3,4,6 and 12 [tex]\ge 0[/tex]

Answer:
a.) 1/2
b.) 1/8
c.) 5/8
d.) 1/2
Step-by-step explanation:
for A it is asking for probability of 1 and is 1/2 of the circle
for B it is asking for probability of 3 and it is 1/2 of and 1/4 of the circle so 1/8
for C it is asking for probability of the odd numbers and there is tow odd numbers 1 and 3 the probability of 1 is 1/2 and the probability of 3 is 1/8 adding them up will give you 5/8
for d it asks for the probability of at least 2 so therefor 2, 3, and 4 and they are 1/8 + 1/8 + for 1/4 = 1/2

What expression is equivalent to 16 + 2 ⋅ 36?
to figure this one out we need to simplify the expression
16x²-36 start by taking out the greatest factor of 16 and 36 which is 4
4(4x²-9) then since this is the difference of squares (meaning both 4 and 9 are squares and it is subtraction) this one is easy, just square the parenthasis and seperate them to get
4(2x+3)(2x-3)
I hope I've helped!
The expression [tex]\rm 16x^2-36[/tex] is equivalent to 4(2x+3)(2x-3).
It is given that the expression [tex]\rm 16x^2-36[/tex]
It is required to simplify this expression.
What is polynomial?Polynomial is the combination of variables and constants in a systematic manner with "n" number of power in ascending or descending order.
We have an expression:
[tex]=\rm 16x^2-36[/tex]
As we can see in the above expression we can take out 4 because 4 is the common factor of 16 and 36.
[tex]=\rm 4(4x^2-9)[/tex] or we can write it as:
[tex]\rm = 4((2x)^2-3^2)[/tex]
We know that the:
[tex]\rm (a^2-b^2) = (a+b)(a-b)[/tex]
By using the above formula, we get:
[tex]\rm = 4(2x+3)(2x-3)[/tex]
Thus, the expression [tex]\rm 16x^2-36[/tex] is equivalent to 4(2x+3)(2x-3).
