This is how you solve this problem:
.10d + .05n = 5.25
(plug in the number of dimes we have)
(21 x .1) + .05n = 5.25
(multiply number of dimes x value of the dime)
2.10 + .05n = 5.25
(subtract 2.10 from both sides)
.05n = 3.15
(divide both sides by .05 to get the number of nickels)
n = 63 nickels
Hope this helps!
Answer:
first off, take pic right side up next time. secondly, it's the forth one down
Step-by-step explanation:
36/96 x 100= 37.5% is the answer
So lets ABCD are the sides of the square and AB=CD, AC=BD and the Angle ABC = 90 so therefore by making a diagonal we can use the SAS or SSS congruency for two triangles, so we can prove two triangles are equal and that is why the shape is square.
Answer:
Step-by-step explanation:
a = 180 - 100
= 80 degrees
b = 180 - 80
= 100 degrees
c = 180 - 135
= 45 degrees
