Sonji has $5.25 in nickels and dimes.The coin value can be modeled by the equation 0.10d + 0.05n = 5.25, where d represents the

number of dimes and n represents the number of nickels. If Sonji has 21 dimes, how many nickels does she have? 35 42 63 105
**The answer is 63. If anyone still wants to answer this, go ahead, I'll be generous and give brainiest if you explain well enough.**

Alright so this problem already gave u an equation so all we have to do is plug in value for d and find n.

.10(21) + .05n = 5.25
2.1 + .05n = 5.25
.05n = 3.15
n = 63
I know u already know the answer but it doesn't hurt to still answer and receive a brainiest.

Suppose that the position of one particle at time is given by x1=3sin t, y1 = 2 cos t, 0 ≤ t ≤ 2π and the position of a second p
Mashcka [7]

Answer:

there is no collision between the particles

Step-by-step explanation:

for the first particle

x1=3sin t, y1 = 2 cos t, 0 ≤ t ≤ 2π

for the second particle

x2 = -3 + cos t, y2 = 1 + sin t, 0 ≤ t ≤ 2π

then for the collision

x1=x2 → 3*sin t = -3 + cos t → sin t= -1 + (cos t)/3→ 1+ sin t = (1/3)cos t  

y1=y2 → 1 + sin t = 2 cos t → (1/3)cos t  = 2 cos t →(1/3) = 2

since 1/3 ≠ 2 there is no collision between the particles
