The answer is C. Hope this helps!
I believe it’s 8 because 24 divided 75% is 32.
Answer:
Step-by-step explanation:
v(5v-7)=0
We multiply parentheses
5v^2-7v=0
a = 5; b = -7; c = 0;
Δ = b2-4ac
Δ = -72-4·5·0
Δ = 49
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
v1 = −b−√Δ/2a
v2 = -b+√Δ/2a
√Δ = √49 = 7
v1 = -(−7)−7/2*5 = 0/10 = 0
v2 = -(−7)+7/2*5 = 14/10 = 1+2/5
Don’t no but will check on goggles
Number of boxes = 11
1 box = 6 bags
11 boxes = 6 x 11
11 boxes = 66 bags
1 bag = 45 marbles
66 bags = 45 x 66
66 bags = 2970 marbles
Answer: The shop ordered 2970 marbles.
