Answer:
a = 29
u = 12
Step-by-step explanation:
32 + 7u + 9 + 2a - 3 = 3a + 7u + 9
32 + 2a - 3 = 3a
a = 29
3(29) + 7u + 9 = 180
7u = 180 - 96
7u = 84
u = 12
Answer:
14m
Step-by-step explanation:
The area of a circle is given by
A = pi r^2
153.86 = 3.14 r^2
Divide each side by 3.14
153.86 /3.14 = r^2
49 = r^2
Take the square root of each side
sqrt(49) = sqrt(r^2)
7 = r
We want the diameter which is twice the radius
d = 2r
d =2*7
d =14
Given:
The pairs of angles are:
36°,24°
18°,72°
96°,84°
To find:
Whether each pair of angle measurements are complementary, supplementary or neither.
Solution:
Two angles are complementary if there sum is 90 degrees.
Two angles are supplementary if there sum is 180 degrees.
For 36° and 24°,
So, this pair is neither complementary not supplementary.
For 18° and 72°,
So, this pair is complementary.
For 96° and 84°,
So, this pair is supplementary.
A&d i think.. but basically the equation needs to be modeled where the answer will be a 14° difference
First, find the total amount of socks, these will be your options. There are 10
So, your probability of getting a blue sock the first time is 3/10. Them, you replace it, meaning it is no more an option, this brings the number of options that you have down to 9. to get a red sock, you will have a probability of 4/9. But since the 2 events are independent (they are related), we will need to multiply both their probability.
3/10 x 4/9 = 12/90 = 2/15
