Sorry for the wait, laptop is being slow :/
I hope this helps.
Answer:
30
Step-by-step explanation:
let number of questions in the test be x
9 of the first 10 questions are correct
so only x-10 questions remain
3/10 of the (x-10) = 3/10(x-10) questions are correct
scored 50% for the whole test
so only half of x = x/2 questions are correct
combining the above:
9+3/10(x-10) = x/2
9+3/10x-3=x/2
9-3=(1/2-3/10)x
1/5x=6
x=30
The formula for the volume of a cone is (1/3)*pi)*r^3*h. Here, r = 2 units.
Thus, the volume of this particular cone is:
V = (1/3)(3.14)((2 units)^2*(9 units). Please do the math, and then round off your answer to 2 decimal places.
To isolate x , multiply both the sides by ( <u>5/23</u> )
<h3>What is an Equation ?</h3>
An equation is formed when two algebraic expressions are equated using an equal sign.
The given equation is
(3/5)(x-10) = 18-4x-1
(3/5)x - 6 = 18-4x-1
(3/5)x - 6 = 17-4x
(3/5)x = 23 -4x
(23/5)x = 23
Step 5 says To isolate x , multiply both the sides by <u>(5/23)</u>
x = 5
