Step-by-step explanation:
Since this circle is partial we will divide the area of the whole circle by 2
the area of a circle is expressed by [tex]\pi r^2[/tex] so insert 14 for the radius.
[tex]14^2\pi[/tex]
[tex]196\pi[/tex]
divide the area by 2
[tex]98\pi=307.876[/tex]

Solve the triangle. A = 46°, a = 31, b = 27
Answer:
A=46 degrees, B=33.4 degrees, C=100.6 degrees
a=34, b=27, c=48.2
Step-by-step explanation:
(a/sin(A)) = (b/sin(B)) = (c/sin(C))
we are given
(34/sin(46)) = (27/sin(B))
34sin(B) = 26sin(46)
34sin(B) = 18.702834809
sin(B) = 0.550083377
note use inverse sin function to find angle B
B = 33.372733167 approx 33.4 degrees then
C = 180 - (46 + 33.4) = 100.6
Then, (b/sin(B)) = (c/sin(C))
27/0.550083377 = c/0.982935349
0.550083377 * c = 27 * 0.982935349
0.550083377 * c = 26.539254427
c = 48.245876056 approx 48.2 .
Lastly, you get: A=46 degrees, B=33.4 degrees, C=100.6 degrees
a=34, b=27, c=48.2

Xavier writes a ratio out of 18 as the decimal 0.22222222.
Answer: 4/18
Step-by-step explanation:
The ratio 4:18 can be written as the decimal 0.22222222, so the value in the numerator is 4.
What is the ratio?It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.
We have:
Xavier writes a ratio out of 18 as the decimal 0.22222222.
Let's suppose the x out of 18 can be written as 0.22222222
x/18 = 0.22222222
x = 3.999999 ≈ 4
It means 4/18 can be written as 0.22222222
Thus, the ratio 4:18 can be written as the decimal 0.22222222, so the value in the numerator is 4.

What is Number System?A number system is defined as the representation of numbers by using digits or other symbols in a consistent manner.
The given sentences are
(A) Tylers puppy gained 5 pounds.
This we can take as a positive number. Because here the value is increasing. whenever we use gained means it is positive.
Tylers puppy lost 5 pounds is the negative number.
(b) The aquarium leaked two pounds of water
This we can take as a Negative number. Because here the value is decreased. whenever we use leaked means it is negative.
The aquarium added with two pounds of water is a positive.
(c) Andrew received a gift of $10.
This we can take as a positive number. Because here the value is increasing. whenever we use received means it is positive.
Andrew gifted a gift of $10.
This we can take as a Negative number. Because here the value is decreased. whenever we use gifted means it is negative.
(d) Kiran gave a gift of $10
This we can take as a Negative number. Because here the value is decreased. whenever we use gave means it is negative.
Kiran received a gift of $10 is positive.
(e) A climber descended 550 feet.
This we can take as a Negative number. Because here the value is decreased. whenever we use descended means it is negative.
Hence positive, Negative , Positive, Negative, Negative,.

A is wrong because radians really refers to the arc with respect to the angle. The opposite is true with A.
D is wrong because the arc is actually bigger than the radius given 1.5 radians.
E is wrong because the area of the whole circle is defined as 2π radians, 1.5 rad × 1.5 = 2.25 rad is (405/π)° and 2π radians is 360° (2π × 180 / π)°.
F is wrong because the circumference of a circle is 2πr.

An online store sells flower arrangements for birthdays and other special events. In a review of their production costs, the
online store found the mean wholesale cost of one shipment of vases was ĉ = 54 dollars, with a margin of error of 5
dollars.
Construct a confidence interval for the mean cost (in dollars) for one shipment of vases.
Answer: A confidence interval for the mean cost (in dollars) for one shipment of vases = (49,59)
Step-by-step explanation:
Confidence interval for mean: Mean ± Margin of error
Given: The online store found the mean wholesale cost of one shipment of vases was ĉ = 54 dollars, with a margin of error of 5 dollars.
A confidence interval for the mean cost (in dollars) for one shipment of vases
[tex]=(54-5, 54+5)\\\\=(49,59)[/tex]
Hence, a confidence interval for the mean cost (in dollars) for one shipment of vases = (49,59)
What is the slope of the line?
Answer:
-7/4
Step-by-step explanation:
Hi,
To find the slope of the line, get two points, and divide the change in y over the change in x. So, let's find two points.
(1,-3) and (-3,4)
Change in y: 4 - (-3) = 7 (Remember when you subtract a negative, you add)
Change in x: -3 - 1 = -4
7/-4 = -7/4
-7/4 is your slope.
