Answer:
60 liters of 20% solution & 20 liters of 60% solution
Step-by-step explanation:
80*0.3=.2x+0.6(80-x)
24=0.2x+48-0.6x
-24=0.2x-0.6x
-24=0.4x
24=0.4x
60=x
Hope this helps!! This is step by step btw!
1) The measures of the opposite angles of an inscribed quadrilateral are supplementary, add up to 180.
That means that angle ROP and angle RQP are supplementary.
We can add them and set them equal to 180 so that we can solve for x first.
∠ROP + RQP = 180
x + 17 + 6x - 5 = 180
7x + 12 = 180
7x = 168
x = 24
Now use the 24 for x and solve for the measure of angle ROP.
∠ROP = x + 17
∠ROP = 24 + 17
∠ROP = 41
The answer is A
2) The answer is A.
Hope this helps :)
Answer:
B. They say that doing homework leads to his success in school.
Step-by-step explanation:
Looking at the answers, C and D already make sense, so they're not the answers. The answer A does not have an unclear antecedent because "my mom and me" would not be written as "my mom and I". B is the only answer left. If you look at the sentence, it begins with "they", and it ends up saying "his success in school". This sentence includes a confusing antecedent because the sentence does not define the person who it is describing.
Sorry if this explanation was confusing. I hope this helps! Have a great day!! C:
Answer:
0.5cm^3
Step-by-step explanation:
volume of rectangular prism= length x width x height
1/4cm x 1/2cm x 4cm =
0.25cm x 0.5cm x 4cm =
0.5cm^3
I have absolutely no idea. sorry that i didn’t answer but thanks for the second answer that i needed to ask my question. i’m stupid do i have no idea what it’s asking. sorry
