Step-by-step explanation:
First, you need to get rid of all the blue slices, leaving 6 behind. Since they are all less than 9, you have a 6/10 chance of getting a white slices less than 9 :)
Hope this helps! :D
Answer:
price of a computer that she could afford R 9230.769
Step-by-step explanation:
Given data
amount pay = R500 per month = 500 × 24 = R 12000 total pay
time period =24 months = 24 /12 = 2 years
rate = 15 % per annum
to find out
price of a computer that she could afford
Solution
we know formula
Amount Paid = Principal × (1+(RT/100))
put value principal pay and R and T and we get
principal = Amount / (1+(RT/100))
principal = 1200 / (1+(15 ×2 )/100))
principal = 9230.769
price of a computer that she could afford R 9230.769
Answer:
Step-by-step explanation:
The equation of a straight line can be represented in the slope intercept form as
y = mx + c
Where
m = slope = (change in the value of y on the vertical axis) / (change in the value of x on the horizontal axis)
The equation of the given line is
9x+7y=4
7y = 4 - 9x = -9x + 4
y = -9x/7 + 4/7
Comparing with the slope intercept form, slope = -9/7
If the line passing through the given point is perpendicular to the given line, it means that its slope is the negative reciprocal of the slope of the given line.
Therefore, the slope of the line passing through (7,-4) is 7/9
To determine the intercept, we would substitute m = 7/9, x = 7 and y = - 4 into y = mx + c. It becomes
- 4 = 7/9×7 + c = 49/9 + c
c = - 4 - 49/9
c = - 85/9
The equation becomes
y = 7x/9 - 85/9
