Answer:
Ella's Grade: 15
Minh's Grade: 16
Step-by-step explanation:
If each grade has 20 girls in the grade, then that implies effectively that the ratios would apply via fractions, which are 3:4 and 4:5. As such, take both Fractions and increase them both to 20: 15:20 and 16:20.
Answer:
the answer is 119g
Step-by-step explanation:
x-120/4.3=-0.25
x-120=-1075
x=118.925=119g
Answer:
Factoring
Step-by-step explanation:
x^2 + 7x = x(x + 7) = 0
So
x = 0 or x = -7
Answer:
8000 cubes
Step-by-step explanation:
Given that 1KL is 1 Kilo liters
Then conversion of 1KL to cm³ => 1,000,000 cm³
Therefore, since we have a cube to be 125 cm³
Hence, to find the number of cubes of ice blocks that would make 1KL
We divide 1,000,000 cm³ from 125 cm³
=> 1,000,000 ÷ 125
=> 8,000
Therefore, the correct answer is 8,000 cubes
The two equations are: 3x + 2y = 36.50 (I)2x + 5y = 50 (II)Eliminating x from the two equations by subtraction:first we multiply equation I by 2 and equation II by 36x + 4y = 736x + 15y = 150Subtracting the two,-11y = -77y = 7He earns $7 at the coffee cartSubstituting y into equation I,3x + 14 = 36.5x = $7.50Therefore, he earns a greater wage of $7.50 at the library, the answer is C
