Also when multiplying 60% u dont multiply by 60 u multiply it by 0.6
Hope this help and sry for the bad grammar
Answer:
y = 3x -5
Step-by-step explanation:
y = mx + b
for (5, 10)
b = y - mx = 10 - 3 x 5 = - 5
y = 3x -5
for (2,1)
check: 1 = 2 x 3 -5
A is the correct answer. 23/40=0.575 and 4.6/8= 0.575 as well.
Answer:
1/6 is the probability for each event, so P of all three = 1/(6^3)=1/216
Step-by-step explanation:
Answer:
2 %
Step-by-step explanation:
Money borrowed, Principal, P = $ 700
time of investment, T = 3 years
Total interest paid, Simple interest, S.I = $ 42
Let the rate of interest is R.
Use the formula for simple interest.
![S.I. =\frac{P\times R\times T}{100}](https://tex.z-dn.net/?f=S.I.%20%3D%5Cfrac%7BP%5Ctimes%20R%5Ctimes%20T%7D%7B100%7D)
By substituting the values
![42 =\frac{700\times R\times 3}{100}](https://tex.z-dn.net/?f=42%20%3D%5Cfrac%7B700%5Ctimes%20R%5Ctimes%203%7D%7B100%7D)
4200 = 2100 R
R = 2 %
Thus, the rate of interest is 2%.
