The area of the shaded sector is shown. Find the radius of circle M. Round your answer to the nearest hundredth.
Answer:
See Explanation
Step-by-step explanation:
The question is incomplete, as the sector, its area and the angle at the center are not given.
I will solve this using the following illusration
The area of a sector is:
[tex]Area= \frac{\theta}{360} * \pi r^2[/tex]
Assume that:
[tex]\theta = 120[/tex]
[tex]Area = 20[/tex]
The equation becomes
[tex]20= \frac{120}{360} * \pi r^2[/tex]
Simplify
[tex]20= \frac{1}{3} * \pi r^2[/tex]
Take: [tex]\pi = 3.14[/tex]
[tex]20= \frac{1}{3} *3.14* r^2[/tex]
Cross Multiply
[tex]3.14 * r^2 = 20 * 3\\[/tex]
Solve for [tex]r^2[/tex]
[tex]r^2 = \frac{20 * 3}{3.14}[/tex]
[tex]r^2 = 19.11[/tex]
Take square roots
[tex]r = \sqrt{19.11[/tex]
[tex]r = 4.4[/tex]
The radius of the sector of a circle whose area is 20 square units and angle subtends at the center of 120° is 4.4 units.
What is a circle?It is a locus of a point drawn equidistant from the center. The distance from the center to the circumference is called the radius of the circle.
The angle subtends at the center is 120 degrees.
The area of the circle is 20 units.
We know that the area of a circle is given as
[tex]\rm Area = \dfrac{\theta }{360} \pi r^2[/tex]
Then we have the radius of the sector will be
[tex]\rm r = \sqrt{\dfrac{360*20}{120*\pi}}\\\\\\r = 4.37 \approx 4.4[/tex]
The radius of the sector is 4.4 units.

Answer:
The probability of spinning red is [tex]\frac{1}{3}[/tex], the probability of spinning a 1 is [tex]\frac{1}{6}[/tex], the probability of spinning an odd number is [tex]\frac{1}{2}[/tex], and the probability of spinning a 9 is 0.
Step-by-step explanation:
Since there are a total of 6 possible outcomes, you can use this in the following questions. There are 2 red tiles, so the probability of spinning red is [tex]\frac{2}{6}[/tex] or [tex]\frac{1}{3}[/tex]. Since there are only one 1 tile, the probability of spinning a 1 is [tex]\frac{1}{6}[/tex]. Since there are three odd numbers, the probability of spinning an odd number is [tex]\frac{1}{2}[/tex]. Since there are no 9 in the spinner, the probability of spinning a 9 is 0 or never.

In which set do all of the values make the inequality 3x-7_>11 true? {6,11,15} {0,7,12} {−2,3,6} {−5,0,5}
Answer:
{6, 11, 15}
Step-by-step explanation:
Given the inequality expression 3x-7≥11
Add 7 to both sides
3x-7+7≥11+7
3x ≥ 18
Divide both sides by 3
3x/3 ≥ 18/3
x≥6
Hence the solution to the inequality are the values of x greater than or equal to 6. Hence the required solutions are {6, 11, 15}

A farmer sells 8.6 kg of Pierce an apple at the Farmers Market two fifths of the wait is pears and the rest is apples how many kilograms of apples did she sell at the Farmers Market
Answer:
Weight of Pears = 3.44 Kgs
Weight of Apple = 5.16 Kgs
Step-by-step explanation:
Given
The total weight of the Pears and the apple is 8.6 Kg
Out of this total weight, the weight of the pears is 2/5
Hence, weight of the Pears is 2/5 * 8.6 = 3.44 Kg
Weight of the Apple is equal to 8.6 -3.44 Kgs = 5.16 Kgs
Weight of Pears = 3.44 Kgs
Weight of Apple = 5.16 Kgs

Jack is selling used computers. he is paid $15/h plus a 5% commission on sales. What dollar amount of computer sales must jack make to earn $1000 in a 40-h work week.
Answer:
8000
Step-by-step explanation:
Jack sold worth $8000 computer sales in the last week.
What is the percentage?A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.
Given, Jack is selling used computers. He is paid $15/h plus a 5% commission on sales.
He made $1000 in a 40-h week,
∴ He made $(15×40) = $600 for his work hours and $(1000 - 600)
= $400.
So, $400 dollars in 5% of the total sales and assuming he made a sell of $x.
∴ (5/100)×x = 400.
0.05x = 400.
x = 400/0.05.
x = 8000.

The following statement tells one way to map preimage points to image points when performing a transformation in the coordinate plane. (x, y) → (x + 8, y − 3) This can be read, “The point with coordinates (x, y) is mapped to the point with coordinates (x, y) → (x + 8, y − 3).” With this transformaƟon, for example, (3, 5) is mapped to (3 + 8, 5 – 3) or (11, 2). The figure below shows how the triangle ABC is mapped to A′B′C′. Notice that the pre‐image and image appear to be congruent. Directions: Answer the following questions, showing all pertinent work.
