Looks like the answer is 72.89 degrees, which is roughly equal to 73 degrees.
Answer:
the radius of sphere X is 2 times larger than the radius of sphere T
Step-by-step explanation:
Given
Surface area of sphere, T =452.16
Surface area of sphere, X= 1808.64
how many times larger is the radius of sphere X than the radius of sphere T?
Finding radius of both spheres:
Surface area of sphere is given as
A=4πr^2
Now putting value of Ta=452.16 in above formula
452.16=4πrt^2
rt^2=452.16/4π
rt^2=35.98
Taking square root on both sides
rt=5.99
Now putting value of Xa=1808.64 in above formula
1808.64=4πrx^2
rx^2=1808.64/4π
rx^2=143.92
Taking square root on both sides
rx=11.99
Comparing radius of sphere X and the radius of sphere T
rx/rt=11.99/5.99
= 2.00
rx=2(rt)
Hence the radius of sphere X is 2 times larger than the radius of sphere T!
So, you have 3/4x + 5/8 = 4x. We can do this in two ways. Since fractions are harder to deal with, we can turn the fractions into whole numbers.
First we need to find the LCD (Least Common Denominator) between 4 and 8, which is 8. So multiply the 3/4x by 2/2, which gives you an equivalent fraction of 6/8x.
So now we have 6/8x + 5/8 = 4x. Now multiply both sides by 8, to get rid of the denominators of the fractions. That gives us 6x + 5 = 32x. Now use the subtraction property of equality to subtract 6x from both sides giving us 5 = 26x.
Now you can use the division property of equality to divide 26 on both sides, which gives us x = 5/26.
Hope this helps. :D Feel free to ask any other questions, and if you have any questions about my explanation, don't hesitate to ask.
Answer:
I believe your answer is A.
Step-by-step explanation:
2x2x2
2x2=4
4x2=8
Therefore, x=2.
