You need to represent it as 2x + 10 = 50
Answer: He made 110 kilograms of 9.09% salt solution.
Step-by-step explanation:
Given: Mass of water= 100 kg
Mass of salt= 10 kg
Total mass of the solution: 100kg+10kg= 110 kg
The percent of salt in solution=
∴The percent of salt in solution
Therefore, He made 110 kilograms of 9.09% salt solution.
Answer:
A = 10.9 cm^2
Step-by-step explanation:
If a circle has a radius of 13 and a sector defined by a 7.4 degree arc, the area, in cms, of the sector is 10.9 cm^2 or 10 cm^2 to the nearest tenth.
C, because first of all, it is asking for m, the number of muffins, and not b, the number of blueberries. So, we can eliminate b and d. Now we can decide between A and C.A) is m=b+144, and it is is false because it will not work for all of the table. C is now our only option, so it is correct. :) Hope this helps!!! :)
Given:
diameter = 14 inches
radius = 14 inches / 2 = 7 inches
Circumference of a circle = 2 π r = 2 * π * 7inches = 14 inches * π
Area of a circle = π r² = π * (7in)² = π * 49in²
C = 14π and A = 49π
