Surface Area of a Sphere: SA = 4πr²Step-by-step explanation:
Step 1: Define
SA = 10.1 m²
Step 2: Find Radius r
Substitute [SAS]: 10.1 = 4πr²Isolate r term: 10.1/(4π) = r²Isolate r: √[10.1/(4π)] = rRewrite: r = √[10.1/(4π)]Evaluate: r = 0.896511Round: r ≈ 0.9Answer:
0.9
Step-by-step explanation:
4(pi)r²= 10.1
4 × (pi) × r² = 10.1
r² = 10.1 / (4×(pi) )
r² = 0.8037
Therefore, r= 0.8965

Raj polled 100 students in his class to compare the number of hours that boys and girls played video games each week. The results of his survey are shown below. Which gender shows greater variability in their playing time?
Hours of Video Game Time per Week for Boys
A box-and-whisker plot. The number line goes from 0 to 28. The whiskers range from 0 to 28, and the box ranges from 9 to 17. A line divides the box at 14.5.
Hours of Video Game Time per Week for Girls
A box-and-whisker plot. The number line goes from 0 to 28. The whiskers range from 0 to 28, and the box ranges from 3 to 15. A line divides the box at 6.
Boys show greater variability because the 3rd quartile for boys is 17 but only 15 for girls.
Boys show greater variability because the median playing time for boys is 14.5 but only 6 for girls.
Girls show greater variability because the interquartile range for girls is 12 for girls but only 8 for boys.
Girls show greater variability because the data for the girls is skewed toward the lower end of the box plot.
Answers
Answer:
c is the correct answer i took the test
Step-by-step explanation:
The gender that shows greater variability in their playing time is C. Girls show greater variability because the interquartile range for girls is 12 for girls but only 8 for boys.
How to find the interquartile range?For the males, the interquartile range will be:
= Third quartile - First quartile
= 17 - 9
= 8
For the females, the interquartile range will be:
= Third quartile - First quartile
= 15 - 3
= 12
Therefore, girls show greater variability because the interquartile range for girls is 12 for girls but only 8 for boys.

please help in math : lenght of rectangle is width+7m.
and width of this rectangle is 1/3 of lenght. find lenght of rectangle.
....please help and explain....
Answers
L=W+7
W=1/3L
we can substitute the width in the first relation with 1/3L
L=1/3L+7
we move1/3L to the left
L-1/3L=7
we multiply by 3 to remove the denominator
3L-L-21
2L=21
L=21/2=10.5cm
Answer:
l = (21/2)m
Step-by-step explanation:
Let's call the length l and width as w.
l = w+7m
(1/3)l=w (Plug in the w value into the first equation)
l = (1/3)l+7m (Now, isolate the l)
(2/3)l = 7m (Multiply both sides by 3/2)
l = (21/2)m

Answers
Answer:
You will need 20 sides to complete the loop.
Step-by-step explanation:
The question isn't quite clear given how small the corner is, but I assume that we are looking to complete the circle if the pentagon and square are repeated in a loop
We can also see - assuming that those are proper equal-sided polygons, that PQ is the same length as PV
With that in mind, We can solve this by noting that the angle of a corner in a square is 90 degrees, and in a pentagon it's 108 degrees.
108 - 90 is equal to 18. This means that PQ is at eighteen degrees to YP. Also, QM, (which will be equivalent to the next VP is eighteen degrees to PQ.
This means that each polygon is rotated 18 degrees relative to it's neighbour.
With all that we can say that the total polygons we need to form a circle is 360/18 = 20, So you will need 20 polygons, or ten squares and ten pentagons to complete the loop.
