Hey there! :D
25% represents a quarter of a number.
If 21 is a quarter of a number, multiply it by 4.
21*4= 84
21 is 25% of 84.
I hope this helps!

Answer: d. 2 divided by cot 40 degrees
Step-by-step explanation: in this right triangle, we are given an angle and the adjacent side of the angle. now we have to find for the length of the opposite side. the formula that relates these 3 variables is the tan function which states that:
tan θ = opposite side / adjacent side
where opposite side is the height of the sail
substituting the values into the formula:
tan (40) = height / 2
rearranging in terms of height:
height = 2 * tan (40)
since tan θ = 1 / cot θ, therefore:
height = 2 / cot (40)

Answer:
cosine = √31/6
Step-by-step explanation:
It is given that,
sine=√5/6
we know that, sine = opposite side/Hypotenuse
<u>To find Adjacent side</u>
Adjacent side = √(Hypotenuse² - opposite side²)
Adjacent side =√(6² - √5² ) = √(36 - 5 ) = √31
<u>To find cosine</u>
cosine = Adjacent side/Hypotenuse
cosine = √31/6
when there is no number with redical sign here it is equivalent to the exponent " 1/2 "
but when it is 3 under redical x that means it is x^1/3
In first one 8 ^(9/2) is same as ( redical 8 ) ^9
In part B it is (3 under redical 125)^9 = ( 125 )^ 9/3 so this also same thing
In part C it is ( 12)^2/7) but the ( redical 12 ) ^7 is equal to ( 12)^7/2 so these two are not equivalent
in part D it is 4^1/5 but ( redical 4) ^5 = 4^( 5/2 which is also not equivalent
Answer : only A and B are equivalent
Answer:
Two points, one at 4 and one at 6.
Step-by-step explanation:
<u>Equations with absolute value
</u>
The absolute value of a number x denoted as |x| is a number with the same magnitude with a positive sign. When we know the result of an absolute value, we cannot know if the original number is positive or negative.
If |x| = a, a>=0, then x=a or x=-a
The equation to solve is |x – 5| = 1. If we apply the above criteria, then
x-5=1 or x-5=-1
Which gives us two possible solutions for x
x=6
x=4
The correct answer is
Two points, one at 4 and one at 6.
