10d+ 25q+5n= 805
D= n+8
Q= n+ 5
10d+ 25q+5n= 805
10(n+8)+25(n+5)+5n=805
10n+80+25n+125+5n=805
40n+205=805
40n=805-205
40n= 600
N=600/40
N= 15
D= n+8
D= 15+8
D= 23
Q=n+5
Q=15+5
Q=20
So 15 nickels ,23 dimes and 20quarters .
To check
15(0.05)= $0.75
23(0.10)=$2.30
20(0.25)=$5.00
Add it
5.00+2.30+0.75=8.05
7.30+.75=8.05
8.05=8.05
We know, Circumference = <span>π * Diameter
8</span>π = <span>π * d
d = 8</span>π / <span>π
d = 8 cm
In short, Your Answer would be Option D
Hope this helps!</span>
Answer:
The degree of the polynomial is found by looking at the term with the highest exponent on its variable(s). Examples: 5x2-2x+1 The highest exponent is the 2 so this is a 2nd degree trinomial. 3x4+4x2The highest exponent is the 4 so this is a 4thdegree binomial.
Step-by-step explanation:
Answer:
22π in.
Step-by-step explanation:
circumference: 2 × π × r
=> 2 × π × 11 = 22π
