Mei has 60 milliliters of a solution that is 35% nitric acid. How many milliliters of nitric acid does the solution contain?
(answer this and show your work please)
The solution contains _answer here_ milliliters of nitric acid.
Answer:
21ml
Step-by-step explanation:
60ml. 35% acid. What is 35% of 60 ml?
÷10 to find 10%
60÷10=6
6=10%
But this is no use
because you cannot multiply 10%to get 35%
(35% is not a multiple of 10)
So we try...
10%÷2=5%
So ÷2 to find 5%
6÷2=3
So 3=5%
5%x7=35%
So, we do
3x7=21
So 35%=21
Answer:
21ml

Answer:
6 2/3 or 6 20/30
Step-by-step explanation:
8 2/3 = 8 22/33
1 10/11 = 1 30/33
8 22/33 = 7 52/33
7 52/33 - 1 30/33 = 6 20/30 = 6 2/3
(33 is the common denominator)

if g(x) = X² +3, find g(4)
Answer:
g(4) = 19
General Formulas and Concepts:
Pre-Alg
Order of Operations: BPEMDASStep-by-step explanation:
Step 1: Define
g(x) = x² + 3
g(4) is x = 4
Step 2: Solve
Substitute: g(4) = 4² + 3Evaluate: g(4) = 16 + 3Add: g(4) = 19Slope-intercept form
find out the y intercept and slope
Answer:
18. Slope (m) = 1/2
Y-intercept (b) = -6
19. Slope (m) = 2
Y-intercep (b) = 8
20. y = 1/2 + 6
Step-by-step explanation:
y = mx + b
y - 2x = 8
y = 2x + 8

Is the table above proportional or non-proportional?
Answer: I think you should divide them all and if you get the same answer it’s proportional if you don’t get the same answer it’s non-proportional
Step-by-step explanation:
Answer:
It is non-proportional.
Step-by-step explanation:
The table is non-proportional because it expresses a curved line instead of a straight line.
5x + 2 = 3x + 4(2x - 1) please solve step by step
Answer:
x=1
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
5x+2=3x+4(2x−1)
5x+2=3x+(4)(2x)+(4)(−1)(Distribute)
5x+2=3x+8x+−4
5x+2=(3x+8x)+(−4)(Combine Like Terms)
5x+2=11x+−4
5x+2=11x−4
Step 2: Subtract 11x from both sides.
5x+2−11x=11x−4−11x
−6x+2=−4
Step 3: Subtract 2 from both sides.
−6x+2−2=−4−2
−6x=−6
Step 4: Divide both sides by -6.
−6x
−6
=
−6
−6
x=1
Answer:
x=1

A rectangular poster has an area of 504 square centimeters. The width of the poster is 14 centimeters. How long is the poster?
Answer:
36 sq. cm.
Step-by-step explanation:
We find area by multiplying the length by the width of the poster. But now, in your question we want to find the length of the poster. We are given the area, 504 square centimeters, and the width, 14 centimeters. Since multiplication and division are inverse operations, we will do the opposite of multiplication, division, to find the quotient, the length of the poster. 504 divided by 14 can be written like this: 504 / 14. 504 / 14 = 36 sq. cm. We can check our answer by multiplying 36 and 14 to get 504. So, we know our answer is correct.

i think it is 514
