Here is your answer! The coefficient of xy is 6. To solve this problem, you need to multiply your two polynomials together. I used the FOIL Method- multiply the First two, the Outside two, the Inside two, and the Last two. You can see how I did it on the picture attached. Next, the answer that you get as a result from FOILing is your polynomial. If you look at the number before xy, that is the coefficient. A coefficient is a number that is right before and attached to a variable. I hope this helps you! :))
Answer:
- The hikers carried 17.5 litres of water
- The Koshy family travled 34.5 km while visiting Delhi
Step-by-step explanation:
1-
Multiply 1.75 liters by 10 (the number of days there were hiking) : 17.5 litres
2-
Multiply 11.5 km by 3 (the number of days visiting Delhi) : 34.5 km
We can convert 24/16 to a mixed number. It will be equivalent to 24/16.
24/16
24 ÷ 16 = 1.5
16 can go in to 24 once.
24 - 16 = 8
1 = whole number
8 = numerator
16 = denominator
Lets write our mixed number:-
This can be simplified ^^^^
So, our old mixed number simplified is
So, 24/16 is equivalent to 1.
, 2.
Hope I helped ya!!! xD
Marcia dissolved 1 kg of salt in 3 litres of water
Bobby dissolved 2 pounds of salt in 7 pints of water
We know that
1 litre = 2.11 pints
We also know that
1 pound = 0.4535 kg
Now if we take the case of Bobby, and convert the pound to
kg then
1 pound = 0.4535 kg
2 pounds = (0.4535 * 2) kg
<span> =
0.907 kg</span>
<span>
= 0.91
kg</span>
Bobby dissolved the salt in 7 pints of water
We know
2.11 pints = 1 litre
Then
7 pints = (7/2.11) litre
<span> = 3.32
litres</span>
So we now see that Bobby has dissolved 0.91 kg of salt in
3.32 litres of water
Marcia dissolved 1 kg of salt in 3 litres of water.
So Marcia has made a more concentrated solution since she
has dissolved more salt in less amount of water whereas Bobby has dissolved
less amount of salt in more water.
