Given:
The equation is
[tex]\dfrac{a}{b}=\dfrac{b}{c}[/tex]
To find:
The value of [tex]b^2[/tex].
Solution:
We have,
[tex]\dfrac{a}{b}=\dfrac{b}{c}[/tex]
On cross multiplication, we get
[tex]a\times c=b\times b[/tex]
[tex]ac=b^2[/tex]
[tex]b^2=ac[/tex]
Therefore, the value of [tex]b^2[/tex] is [tex]ac[/tex].

Bobby is 5 less than Kylie's age. Their combined
age is 43. How old is Kylie?
Answer:
Kylie is 24 years old
Step-by-step explanation:
kylie = x
Bobby=x-5
x+x-5=43
2x-5=43
2x=43+5
2x=48
X=24 years old
19
If you subtract 5 off of 43 and divide it by two you find Kylie's age. The reason you divide by two is because there are two people and it is a combined age, meaning you would divide by two.

W-20.5=8 please help me
This is just the same as asking you what number when subtracted by 20.5 will give you an answer of 8. The answer would obviously be 8+20.5=28.5 so w=28.5.
We can also do it in a more algebraic way. By adding 20.5 to both side of the equation which won't change the value.
w-20.5+20.5=8+20.5
w=28.5
Any questions just ask me in the comments of this question :)

Write the equation of a line with an undefined slope that passes through the point (-6,3)
Answer:
x = -6
Step-by-step explanation:
A line with an undefined slope is vertical and is always represented by the equation x = a number. That number, whatever it may be, represents the x-value of all the points it intersects. Thus, take the x-value of the point (-6,3) and put it into the equation. So, the equation must be x = -6.

ans : If you know the length of one of the legs of a 45-45-90 triangle, the other leg has the same length. For this triangle, the other leg has a length of 8*sqrt(2) units. The hypotenuse's length can be found by multiplying the leg's length by sqrt(2).
While parasailing. Ryan spots a dolphin on the water below. If Ryan is 228 feet above the
water and the angle of depression to the dolphin is 15, what is the horizontal distance
between Ryan and the dolphin?
Answer:
850.9 feet
Step-by-step explanation:
The horizontal distance between Ryan and the dolphin is 850.907 feet.
What is Trigonometry?One area of mathematics known as trigonometry examines the relationship between the sides and angles of a right triangle. The relationship between sides and angles is defined for 6 trigonometric functions.
We have,
Ryan is 228 feet above the water and the angle of depression to the dolphin is 15.
Using trigonometry
tan 15 = 228/ x
x= 228/ tan 15
x= 228 / 0.26794919243
x = 850.907 feet

Calculate 48 x 3/8 choose the numbers to complete the equation
Answer:
1. Choose: 3
2. Choose: 144
3. Choose: 18
Step-by-step explanation:
The first thing you do is multiply 48 * 3/8= 18. Then multiply 48 * 1/8= 6. Then divide both answers to get 3, so 48 * 1/8 * 3.
Then to find the second Choose option, you know that 48 * 1/8 * 3= 18; so 18 * 8= 144(to check your answer, divide 144/8 = 18).
Finally, to find the third Choose option, you divide the fraction 144/8 = 18.
