If the circle has a diameter of a team meters in a central angle of 210° what is the area of the sector
Answer:
[tex]Area = 45.82m^2[/tex]
Step-by-step explanation:
Given
[tex]d = 10m[/tex] --- diameter
[tex]\theta = 210^\circ[/tex]
Required
Determine the area of the sector
The ares of the sector is calculated as:
[tex]Area = \frac{\theta}{360} * \pi r^2[/tex]
Where
[tex]r = \frac{d}{2}[/tex]
This gives:
[tex]r = \frac{10m}{2} = 5m[/tex]
So, we have:
[tex]Area = \frac{210}{360} * 3.142 * 5^2[/tex]
[tex]Area = \frac{210}{360} * 78.55[/tex]
[tex]Area = \frac{210 * 78.55}{360}[/tex]
[tex]Area = \frac{16495.5}{360}[/tex]
[tex]Area = 45.82m^2[/tex]

Find the product 8/6n-4 • (9n^2-4).
An expression can be written in rational form by writing it as a fraction with a denominator of
Answer:
The correct answer is 1 for the first part, and 12n+8 for the second part.
Step-by-step explanation: I got them wrong for you guys. Edge 2021.
The product of the expression given is 12n + 8.
What are Expressions?Expressions are mathematical statements which consist of two or more terms and terms are connected to each other using mathematical operators like addition, multiplication, subtraction and so on.
The given expression is ([tex]\frac{8}{6n-4}[/tex]) . (9n² - 4)
Multiplying the numerators together,
([tex]\frac{8}{6n-4}[/tex]) . (9n² - 4) = [8 (9n² - 4)] / [6n - 4]
= {8 [ (3n)² - (2)² ] } / {6n - 4}
We have an algebraic identity, a² - b² = (a + b) (a - b)
Using this identity (3n)² - (2)² = (3n + 2) (3n - 2)
And the expression in the denominator, 6n - 4 = 2 (3n - 2)
([tex]\frac{8}{6n-4}[/tex]) . (9n² - 4) = [8 (3n + 2) (3n - 2)] / [2 (3n - 2)]
The expression 3n - 2 gets cancelled as it lies in both numerator and denominator.
([tex]\frac{8}{6n-4}[/tex]) . (9n² - 4) = [8(3n + 2)] / [2]
= 4 (3n + 2)
= 12n + 8
Hence the product is 12n + 8.

Answer:
Isosceles and Right
Step-by-step explanation:
An Isosceles Right Triangle is a right triangle that consists of two equal length legs. Since the two legs of the right triangle are equal in length, the corresponding angles would also be congruent. Thus, in an isosceles right triangle, two legs and the two acute angles are congruent.
Answer:
Isosceles and right
Step-by-step explanation:
We have a picture of triangle and are asked to name it, look at definitions below :
Isosceles - Geometrical figure with three sides and three angles
Right - Triangle where one angle is a right angle (90°)
Scalene - Triangle where all three sides have different lengths
Acute - Triangle where all three sides are less than 90°
If we look at the triangle, we can tell that it has three sides and three angles, therefore isosceles must be in one of the answer choices. Crossing out the options scalene and acute / scalene and right.
Now we have two options and we need to determine whether this triangle is an acute triangle or is a right triangle.
To figure out so we can look at the angle in the bottom left, which when measures equals to 90°. Therefore making it a right triangle and crossing out the other option.
Our answer left is Isosceles and Right.

A flock of sheep has 182 white sheep and 98 spotted sheep. Which proportion can be used to determine p, the percent of the flock that has spots?
Answer:
D) 98/280 = p/100
Step-by-step explanation:
Since p is the missing percentage, it has to be OVER 100, so C is eliminated.
Total:
182 + 98 = 280
Spotted sheep probability:
98/280 = 0.35 or 35%
To check:
[tex]\frac{98}{280} =\frac{p}{100} \\\\280p=9800\\x=35[/tex]

Find an exponential equation that passes through the points (0, 4) and (2, 9).
Given:
An exponential equation passes through the points (0,4) and (2,9).
To find:
Exponential equation that passes through the given points.
Solution:
Let the required exponential function is:
[tex]y=ab^x[/tex] ...(i)
The function passes through the points (0,4) and (2,9). It means the above equation must be true for these points.
[tex]4=ab^0[/tex]
[tex]4=a(1)[/tex]
[tex]4=a[/tex]
And,
[tex]9=ab^2[/tex]
Substituting [tex]a=4[/tex], we get
[tex]9=(4)b^2[/tex]
[tex]\dfrac{9}{4}=b^2[/tex]
[tex]\pm \sqrt{\dfrac{9}{4}}=b[/tex]
[tex]\pm \dfrac{3}{2}=b[/tex]
In an exponential function b>0. So, [tex]b=\dfrac{3}{2}[/tex].
Putting [tex]a=4,b=\dfrac{3}{2}[/tex] in (i), we get
[tex]y=4\left(\dfrac{3}{2}\right)^x[/tex]
Therefore, the required exponential function is [tex]y=4\left(\dfrac{3}{2}\right)^x[/tex].

Brian and sonya each have a container. They mark their containers to show tenths. Brian and sonya both fill their containers with 0.7 units of juice. However, brian has more juice in him container. Explain how this is possible.
Answer:
Step-by-step explanation:
Brian could have more juice than Sonya in actual sense, This is because the representation used, that is the container has been calibrated to show tenth. This means that decimal values of juice in the container will not show explicit volume beyond tenth. Hence the volume will be rounded.
For instance, if the actual volume of juice Brian has Is 0.74 and that owned by Sonya is 0.69. In actual sense, 0.74 > 0.69 . However, if both pour their juice into the calibrated container, Brian's volume will be rounded to the nearest tenth as 0.7 and Sonya's (0.69) will also be rounded to 0.7.
But in actual sense, Brian has more Juice than Sonya.

1. If you toss a coin 30 times, you expect the coin lands on the tail _____ times.
Answer:
15 times
Step-by-step explanation:
50% of the time, 50% of 30=15
Answer: 15 times
Step-by-step explanation:
A coin has a 50/50 chance to get either heads or tails. 50% of the time it's heads, 50% is tails. So, if you tossed a coin 30 times, you would expect the coin to land on the tail 15 times because 30 / 2 = 15.
