Given :
The ratio of the amount of gold to the amount of silver is 2:5.
To Find :
The weight of gold in the alloy, if there are 80 g of silver.
Solution :
Let, amount of gold is x.
So, the ratio of amount of gold and silver is :
Therefore, the weight of gold in the alloy is 32 g.
Hence, this is the required solution.

0.123601
Step-by-step explanation:
Answer:
228.571428 or estimate it down
Step-by-step explanation:
136 ÷ 119 = 1.14285714
1.14285714 x 200 = 228.571428
Three COLLINEAR points . . .
they determine a line.
An infinite number of different planes can also contain the line,
so the three collinear points don't nail down any specific plane.
Three NON-collinear points . . .
they determine one plane for sure, and only one.
That's why a three-legged stool or tripod is always stable and
doesn't wiggle. No matter how bumpy or rolling the floor or the
ground may be, the ends of the three legs determine exactly one
stable plane, so wherever they fall, they're standing on a stable plane.
The part on top where you sit is stable and doesn't wiggle.
Answer:
100
Step-by-step explanation:
Because adjacent angles in a parallelogram are supplementary, angle 1 and 80 must add up to 180 degrees. Therefore, angle 1 is 180-80=100 degrees. Hope this helps!
