Answer:
I think it's B.
Step-by-step explanation:
Because the equation is 1 - 0.144/24 should represent the amount of emails to be answered after one day.
Answer:
i thinkbit is C but im in 6th grade and at may 5 i. not there yet
The answer choice is C, because the problem is asking for the outcome of either one of the answers. Then you just add them together and the answer is 0.5+0.3=0.8. Hope this helped!
Since the girl scout sold 5 more boxes on the second week, we have (x + 5) number of boxes sold for the second week. Now, for the third week, since it's double that of the second week, we have 2(x + 5). Thus, we have the following:
first week: x
second week: x + 5
third week: 2(x + 5)
Given that the total number of boxes sold for the three weeks is 431. We have
x + (x + 5) + 2(x + 5) = 431
x + x + 5 + 2x + 10 = 431
4x + 15 = 431
4x = 431 - 15
4x = 416
x = 104
We have now the value of x. Using this, we can find the values for the second and third week.
x + 5 = `104 + 5 = 109
2(x + 5) = 2(109) = 218
Answer:
first week: 104
second week: 109
third week: 218
1.2mL will be needed to make 50 mL of a 2% solution
<h3>Ratio and proportions</h3>
Ratio are written in form of fractions.
If 50mL is required for a 2% solution, hence;
50% = 2mL
0.05 = 2mL
In order to determine the required mL for a 30% solution, we will have;
30% =x
0.03 = x
Find the ratios
0.5/0.3 = 2/x
Cross multiply
0.5x = 2(0.03)
0.5x = 0.6
x = 0.6/0.5
x = 1.2mL
Therefore 1.2mL will be needed to make 50 mL of a 2% solution
