Answer:
r = ( q -16)/6
Step-by-step explanation:
In order to rearrange the equation so that r is the independent variable is the same thing as making r the subject of the formula from the given expression
q-10= 6(r+1)
we say,
q - 10 = 6r + 6 ( by using 6 to open the bracket)
we are going to collect the like terms
q- 6r = 6 + 10
q- 6r = 16
q = 16 + 6r
q-16 = 6r
divide both sides by the coefficient of r which is 6
(q-16)/6 = 6r/6
r = ( q -16)/6
Answer:106.38 feet
Step-by-step explanation:
This can be solved by using pythagoras theorem
c=110 feet
b=28 feet
a=?
a=sqrt(110^2-28^2)
=sqrt(12100-784)
=sqrt(11316)
=106.3766 feet
=106.38
Answer:
f⁻¹(x) = x/4 + 1/2
Step-by-step explanation:
To find the inverse of a function, switch the x and y variables, then isolate y.
f(x) replaced y, so you can replace it back.
y = 4x - 2
x = 4y - 2 Switched x and y
x + 2 = 4y Added 2 to both sides
y = x/4 + 2/4 Divided both sides by 4
y = x/4 + 1/2 Simplified
f⁻¹(x) = x/4 + 1/2 Use function notation
20% of 52
Set up a proportion.
20/100 = 52/1
Divide
52*0.2 = 10.40
Final answer: 10.4
Answer:
<h2><u><em>
8</em></u></h2>
Step-by-step explanation:
if the ratio of red to blue circles is 1:3 how many more red circles need to be added to make it a ratio of 3:1
add 8 red =
9/3 = 3/1
