Answer:
Step-by-step explanation:
x + y = 11
.25x + .05y = 1.15
25x + 5y = 115
-25x - 25y = -275
-20y = -160
y = 8 nickels
x + 8= 11
x = 3 quarters
3 quarters and 8 nickels
Answer:
Step-by-step explanation:
diameter = 20
radius = 10 units
Length of Chord = 16 units
The perpendicular from the center to a chord, bisect the chord.
So, base = 16/2 = 8units
Use Pythagorean theorem.
x² + 8² = 10²
x² + 64 = 100
x² = 100 -64
x² = 36
x = √36 = √6*6
x = 6 units
Answer: Width = 9 inches
Length = 12 inches
Step-by-step explanation: A = (w+3)(w)
A = w2 + 3w = 108
w2 + 3y - 108 = 0
This is the factor of the problem: (w - 9) (w + 12) = 0
This equals to w + 12 = 0
w = -12
Then the final answer would be Width = 9 inches
Length = 12 inches.
Hope this helps!
I am joyous to assist anytime!
