Answer:
- 80milliliters of the 10% fungicide solution
- 170milliliters of the 50% fungicide solution
Step-by-step explanation:
let A represent the amount of the 10% fungicide solution
let B represent the amount of the 50% fungicide solution
B milliliters = 50% of B = (50/100)A = 0.5B
Total milliliters = 26% of 200 milliliters = 0.26 * 200 = 52
A milliliters + B milliliters = 200
milliliters
0.1A + 0.5B = 52
- A + B = 200
- 0.1A + 0.5B = 52
using substitution method to solve A and B
- from equation 1 A = 200-B
- insert A = 200 - B in equation 2
0.1(200-B) + 0.5B = 52
20 - 0.1B + 0.5B = 52
20 + 0.4B = 52
0.4B = 52 -20 = 32
0.4B = 32
B = 32/0.4 = 80
since B = 80
A = 200 -B = 200 - 80 = 120
- 80milliliters of the 10% fungicide solution
- 170milliliters of the 50% fungicide solution
Estimation....
20% off means u r paying 80%. 349.99 rounds to 400.
80% of 400.....turn percent to decimal....." of " means multiply.
so 0.8(400) = 320 <== ur estimate
The price dropped 299.99 - 180.55 = 119.44. So we need to find out what percentage 119.44 is of 299.99.
<span>"119.44 is what percentage of 299.99" translates to </span>
<span>119.44 = x * 299.99 </span>
<span>So x = 119.44 / 299.99 = about 0.3981466, which is 39.81% when rounded to the nearest hundredth of a percent.</span>
Square root 75 = square root 25 × square root 5 = 5 square root 5
No because Carmella rounded both of the numbers down. Because she rounded it down to 300+10 there will not be enough space
Hope this helps
