Answer: 14 dimes and 8 quarters
<u>Step-by-step explanation:</u>
dimes ($0.10): x + 6
quarters ($0.25): x
Cost*quantity of dimes + Cost*quantity of quarters = Total value
0.10(x + 6) + x(0.25) = 3.40
0.10x + 0.60 + 0.25x = 3.40
0.35x + 0.60 = 3.40
<u> -0.60 </u> <u>-0.60 </u>
0.35x = 2.80
<u>÷0.35 </u> <u>÷0.35 </u>
x = 8
dimes: x + 6 = 8 + 6 = 14
Answer:
21.
Step-by-step explanation:
The next perfect square below 248 i s 225 ( = 15^2).
So the answer is 248 - 225 = 21.
The ratio of the circumference to the diameter is defined as pi
pi=circumference/diameter
that is how they got pi
in this question it woul be 15.7/5 which would be 3.14,
c=2pir
a=pir^2
c=2pir=16pi
divide both sides by 2pi
r=8
a=pir^2
a=pi8^2
a=pi64
a=64pi in²
Answer:
x= infinite
Step-by-step explanation:
12+8x-8=8x+4
4+8x=8x+4
