Answer: Time taken by Ximena to paint the fence alone = 24 hours
Time taken by Candice to paint the fence alone = 12 hours
Step-by-step explanation:
Let x= Time taken by Ximena to paint the fence alone .
Time taken by Candice to paint the fence alone = x-12
As per given , we have
if x= 4
Time taken by Ximena = 4 hours
Time taken by Candice = 4-12 hours =-8 hours which is not possible. (time cannot be negative)
Therefore, x= 24
Such that
Time taken by Ximena to paint the fence alone = 24 hours
Time taken by Candice to paint the fence alone = 24-12=12 hours
No, they did not eat the same amount. Barry ate less because his sandwich was smaller, so there would be a smaller half. Jonah ate more because his sandwich was bigger, so he would have eaten a bigger half.
Answer:
56 cm squared
Step-by-step explanation:
First things first: Cop one triangle off the rectangle, and attach it to the other one, so the shape looks like a L
Now I can actually solve this:
The left side is 8 cm (because y = 8 cm)
The top is 10 cm
The middle is 6 cm
The inside left is 3 cm
And the very bottom is 2 cm
First, we'll solve for the newly constructed rectangle: 3 x 2. That equals 6.
Next, solve for the longer rectangle: 10 x 5. That's 50.
Now, add the two areas, and we get 56. So the area of the whole thing is 56 cm squared.
(Please keep in mind that I could be wrong, so double check it for me, thanks!)
Answer:
ksh 140
Step-by-step explanation:
When a watch is sold for ksh 126 a loss of x% is made, that is( 100 - x)%
Hence, the loss amount = (126 X 100)/(100 - x)
When the same watch is sold for ksh 154 a profit of x% is made, that is (100 + x)%
Hence, the profit amout = (154 X 100)/(100 + x)
Therefore, (126 X 100)/(100 - x) = (154 X 100)/(100 + x)
12600(100 + x) = 15400(100 - x)
1260000 + 12600x = 1540000 - 15400x
28000x = 280000
x = 10%
In that case for a watch sold for ksh 126 a loss 10% is made, that is( 100 - 10)%
Hence, loss amount = (126 X 100)/90 = ksh 140
∴ the buying price is ksh 140
