What we know: one part of candy costs $6 per kg
another part of candy costs $4.50 per kg
To get a 15kg candy, lets add 6 and 4.5
6+4.5=10.5
Add 4.5 to 10.5
4.5+10.5=15
So, We need 2 kg of the $4.50 candy, and 1 kg of the $6.00 candy.
Answer:
Step-by-step explanation:
- Initial value = $0.03
- Increase rate = 2 times each day
- Time = 30 days
<u>Saving amount after 30 days:</u>
- $0.03*2^30 = $32212254.72
<span>Since the given ratio is blue:black is 4:5
4+5=9
4/9= 0.44 ~ 44%
5/9= 0.56 ~ 56%
Since there are a total of 63 bikes and 44% of these bikes are blue we just multiply 44% with the total number of bikes.
Solution:
1. 0.44 x 63 = 28
2. 0.56 x 63 = 35
Conclusively, there are 28 bikes that are colored blue.</span>
Answer:
a = 12
Step-by-step explanation:
Formula for calculating the slope of a line is expressed as;
m = ∆y/∆x
m = y2-y1/x2-x1
Given
m = 1/2
x1 = a
y1 = 14
x2 = 8
y2 = a
Required.
Value of a
Substitute the given parameters into the formula
1/2 = a-14/8-a
Cross multiply
1(8-a) = 2(a-14)
8-a = 2a-28
Collect like terms
-a-2a = -28-8
-3a = -36
a = -36/-3
a = 12
Hence the value of a is 12
