30% = 30/100
= 0.3
Now if we say that x% of a number is y then it actually means that x% multiplied by that number would be equal to y, thus:
30%*56 = 0.3*56
= 16.8
Answer:
Statement B, C, E are correct
<u>Solution:</u>
We have to find the true statements
We know that,
To find the diameter of a circle, multiply its radius by two
Thus statement E is correct
Also,
To find the diameter of a circle, divide its circumference by π
Thus statement B is correct
circumference of a circle is obtained by multiplying diameter with pi
The circumference of a circle is greater than its diameter
Thus, Statement C is correct
Answer: 9
-------------------------------------------
Look at the graph of f(x). Locate x = 3 on the graph and move to the left of that location. If you get closer and closer to x = 3 from the left side, then you approach y = 3
Do the same for g(x) as well. If you approach x = 3 from the left, then you approach y = 3. It does not matter there is a discontinuity here as we're only worried about approaching x = 3 from the left and not actually getting to that specific x value.
We multiply those y values to get 3*3 = 9 as the answer
Answer:
x = 9
Step-by-step explanation:
2x - 3 = 15
2x = 15 + 3
2x = 18 (divide both sides by 2 to get x)
2x/2 = 18/2
x = 9
Answer:
Option C is correct.
Step-by-step explanation:
We need to find reference angle and signs of sinФ, cosФ and tanФ
We know that 
is equal to 150°
and 150° is in 2nd quadrant.
So, Ф is in 2nd quadrant.
And In 2nd quadrant sine is positive, while cos and tan are negative
The reference angle Ф' is found by: π - Ф
=> Ф = 5π/6
so, Reference angle Ф' = π - 5π/6
Ф' = 6π - 5π/6
Ф' = π/6
So, Option C Θ' = pi over 6; sine is positive, cosine and tangent are negative is correct.
