25q + 10d = 33
B) q + d = 6
0.25q + 0.1d = 33
C) q + d = 33
25q + 10d = 6
D) q + d = 33
0.25q + 0.1d = 6
Answer: D) .
Step-by-step explanation:
We know that $1 = 4 quarters
⇒ 1 quarter =
$1 = 10 dimes
1 dime =
Let 'q' be the number of quarters and 'd' be the number of dimes.
Since, Martin has a combination of 33 quarters and dimes worth a total of $6.
Answer:
q + d = 33 0.25q + 0.1d = 6

Step-by-step explanation:
in negative numbers, it goes the opposite of positive numbers
Answer:
Step-by-step explanation:
If a car is moving across a circular bridge, made in the shape of a circular arc then the force that balances the car when it is on the top of arc will be
n + F = mg
Where n = normal force acting on the car
F = centripetal force
m = mass of the car
We know centripetal force
where m = mass of the car
v = velocity of the car on the top of the arc
r = radius of the arc
Therefore, the expression for the normal force 'n' will be
