Answer:
9) 379.94 mm2
10)19.625 ft2
Step-by-step explanation:
a=(pi)r2
a=3.14(11 mm2)
a=3.14(121 mm2)
a=3.14*121 mm2
a=379.94 mm2
a=(pi)r2
a=3.14(2.5 ft2)
a=3.14(6.25 ft2)
a=3.14*6.25ft2
a=19.625 ft2
Answer:
(I don't know where to round the numbers to, so I'll just put the full areas)
The answer to 9. is: 380.132711 mm², and the answer to 10. is: 19.6349541 ft².
Step-by-step explanation:
The formula for the area of a circle is A = πr². (A = area, π = pi, r = radius.) When you substitute the variables in the formula for the values of question #9, you get A = π(11)². (It's 11 because the radius is half of the diameter, which in this case is 22 mm.) And when you substitute the variables for the values of question #10, you get A = π(2.5)². And from there, you just finish the equations. Hope this helps :)

Answer:
B.
Step-by-step explanation:
The answer is B because 3/5 of 1/2 is less than 1/2. The equation that represents this problem is
3/5 x 1/2 = 3/10
3/10 < 1/2
Therefore, 3/5 is less than 1/2!

[tex]\frac{1}{16}[/tex]
Step-by-step explanation:
Answer:
1/16
Step-by-step explanation:
Anytime you divide fractions by whole numbers, remember this:
Same, change, reciprocal (flip)
In the equation:
3/4 / 12
KEEP 3/4 as it is.
CHANGE the division sign to a multiplication sign.
FLIP 12/1 to 1/12.
The final equation: 3/4 x 1/12
3/4 x 1/12 = 3/48
3/48 simplified: 1/16
Therefore, 3/4 / 12 = 1/16

(a) the given triangle is a isosceles triangle. The two base (non-congruent side) angles (in this case, ∠XYW & ∠XWY) will have the same measurements.
It is given that m∠XYW = 70°, therefore, m∠XWY is also 70°.
Subtract 180 from the two 70° to get m∠X:
180 - (70 + 70) = 180 - 140 = 40°
m∠X = 40° is your answer.

The given triangle is a equilateral triangle (All sides are congruent). If all sides are congruent, it is a equilateral triangle, and if it is a equilateral triangle, then all measurements of the inside angles are the same, 60°

Can somebody help me please is it A,B,C,D
Answers
Answer:
80 degrees
Step-by-step explanation:
The only given angle here is angle 4, which measures 100 degrees.
1) Identify angle relationships
Angle 4 and angle 6 are interior angles, meaning they have a sum of 180 degrees.
2) Solve for angle 6
180-Angle 4=Angle 6
180-100=Angle 6
80=Angle 6
Therefore, the measure of angle 6 is 80 degrees.
I hope this helps!
Answer:
c. 80°
Step-by-step explanation:
We are given a shape with a bunch of lines, and are asked to find what measure is ∠6.
Solving this is simple, we just need to keep notice that what angle is larger than 90 degrees looks like and what under 90 degrees looks like. All angles that are above 90 look wide and huge, while all under is very tiny and skinny.
If we take a look at our hint, angle 4 has the (100 degrees). Look at how wide it is, if angle 6 is tinier than that, then the answers A. and B. are scratched out.
Now 90 degrees is a right angle, looking at angle 6 guarantees that D. is also not correct because it is not a right angle.
Leaving us with C. 80
In a random sample of 5 residents of the state of Maine, the mean waste recycled per person per day was 2.6 pounds with a standard deviation of 0.69 pounds. Determine the 98% confidence interval for the mean waste recycled per person per day for the population of Maine. Assume the population is approximately normal. Step 1 of 2 : Find the critical value that should be used in constructing the confidence interval. Round your answer to three decimal places.
Answers
Answer:
(1.307 ; 3.893)
Step-by-step explanation:
Given that:
Mean, xbar = 2.6
Standard deviation, s = 0.69
Sample size, n = 5
Confidence interval : xbar ± margin of error
Margin of Error = Tcritical * s/sqrt(n)
Degree of freedom (df) = n - 1 = 5 - 1 = 4
Hence Tcritical = 3.747
Margin of Error = 3.747 * 0.69/sqrt(4)
Margin of Error = 1.293
Lower boundary = (2.6 - 1.293) = 1.307
Upper boundary = (2.6 + 1.293) = 3.893
(1.307 ; 3.893)

Find:
Area of one white section
Computation:
Radius of circle = Side of cube / 2
Radius of circle = 12 / 2

One white section = sector of a circle
Area of sector of a circle = [θ/360][π][r]²
Area of sector of a circle = [90/360][22/7][6]²
Area of sector of a circle = [0.25][3.14][36]
