The correct equation would be: 2.) 0.05(x+4) + 0.10x = $1.25
A nickel is worth 5 cents. A dime is worth 10 cents.
no. of nickels = x + 4
no. of dimes = x
nickels + dimes = 1.25
0.05(x + 4) + 0.10x = 1.25
0.05x + 0.20 + 0.10x = 1.25
0.15x = 1.25 - 0.20
0.15x = 1.05
0.15x/ 0.15 = 1.05 / 0.15
x = 7 *no. of dimes.
no. of nickels = x + 4 = 7 + 4 = 11
To check:
0.05(11) + 0.10(7) = 1.25
0.55 + 0.70 = 1.25
1.25 = 1.25
Answer: its 31.4 i think cuz if you divide 157 and 5 you get 31.4 in an hour
Step-by-step explanation:
I divided
Answer:
You would first put it into point slope form which is (y-y_1)=m(x-x_1). Then you would solve for y.
A. <span>0.16 + 0.193 + 0.222 + 0.233 + 0.067 + 0.125 = 84
</span>probabilities are all between 0 and 1 but does not add to 1.
<span>B. 0.35+0.18+ 0.21+ 0.06+ 0.17+ 0.03 = 1
</span>probabilities are all between 0 and 1 and also <span>add to 1.
</span><span>C. (0.01) 11+ (0.01) 12+ (0.01) 13 = 0.11+0.12+0.13 =0.36
</span>probabilities are all between 0 and 1 but does not add to 1.
D. 0.16+0.12+ 0.02+ 0.08+ 0.22+ 0.05+ 0.15+ 0.02+ 0.18 = 1
probabilities are all between 0 and 1 and also add to 1.
E. 0.12-0.02+0.18+0.08+0.15+0.05+0.16+0.27+0.02+ 0.36 -0.15 -0.22 =1
probabilities are all between 0 and 1 and also <span>add to 1.</span>
