Answer:
it’s cross multiplication.
Step-by-step explanation:
I’m wondering if you had a teacher that was trying to explain this and even online I had a teacher who would explain something when nobody understood the topic.
1. 2 * 13 = 26
2. 10 * x = 10x
26 = 10x
Answer:
Total number of people who voted in the elections = 140.
Step-by-step explanation:
Votes received by Freda = 60%
So, the votes received by Sonja = (100 - 60)% = 40%
So difference between the votes of Sonja and Freda = 60% - 40% = 20%
Also Freda won by 28 votes, so difference between their votes = 28 votes
Let the total number of people voted = K
Now, according to the question
20 % of K = 28
⇒ K = 2800/20 = 140
So, the total number of people who voted in the elections are 140.
Area=pi times radius^2
area=36pi
36pi=pi times radius^2
divide both sides by pi
36=radius^2
square root both sides
6=radius
2radius=diameter
2 times 6=12
radius=6
diamater=12
the answers area A and D
(if you know your radius and diameter, you would know that diameter is 2 times radius and you could eliminate 2 choices imedietly (B and C))
Cos (Ф) = 5/12
arcos (5/12) = cos⁻¹ (5/12) = Ф
Then cos⁻¹ (5/12) = 57.769 and Ф = 58
So hmm if you notice the picture below
between 2 and 16, there are 14 units, so, the center is half-way in between, thus, is at y = 7, or -2, 7
because, the major axis is over the y-axis, then the "a" component, goes under the fraction with the "y" in the numerator
