Answer:
35 red marbles
Step-by-step explanation:
So we can put the different color marbles in a ratio. So 7:2:11. If we add all of those up we get 20. We do 100/20 to get 5. Each number in the ratio is equivalent to 5 marbles. Then we do 7*5 to get 35. We can check our work by doing, (7*5) + (2*5) + (11*5) = 100. And it does equal 100 so the answer is correct.
Answer:
y = 2x - 4
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + b ( m is the slope and b the y- intercept )
here m = 2 and b = - 4
y = 2x - 4 ← equation of line
Answer:
The final velocity v is 21.74 m/s.
Step-by-step explanation:
Given:
To find:
Solution:
As we know the third equation of motion is represented as
Substituting the values u, a and s in the above equation we get
1/7(1000) = 1/7(7000/7)
1*7000
7*7
7000
49
1000
7
so 1/7(1000) = 1000/7 or 142 6/7
Answer:
x = 66
Step-by-step explanation:
√(x - 2) + 3 = 11
Subtract 3 from both sides: √(x - 2) = 8
Square both sides: x - 2 = 64
Add 2 to both sides: x = 66
