Step-by-step explanation:
1. a²=25²-15²
a²=(25-15)(25+15)
a²=10×40
a=20
2.b²=10²-6²
b²=(10-6) ×(10+6)
b²=4×16
b=8
Just divide 8.4 by 6. And you’ll get 1.4 ounces on each piece of pizza.
Answer:
Interest earned is $8.75
Total amount of money earned = 708.75
Step-by-step explanation:
Principal = 700
Rate = 2.5%
Time = 6 months = 6/12 years = 0.5 years
Interest = PTR/100
= 700x0.5x2.5/100
= 8.75
Total amount = P + I
= 700 + 8.75
= 708.75
Answer:
x=-5, y=-2. (-5, -2).
Step-by-step explanation:
x-3y=1
-x+6y=-7
-------------
3y=-6
y=-6/3
y=-2
x-3(-2)=1
x+6=1
x=1-6
x=-5
Answer:
102
Step-by-step explanation:
Let the unknown measure be x
So all the angles add up to 180
therefore,
13 + 65 + x = 180
78 + x = 180
x = 180 - 78
x = 102
