Q + d = 63....q = 63 - d
0.25q + 0.10d = 10.80
0.25(63 - d) + 0.10d = 10.80
15.75 - 0.25d + 0.10d = 10.80
-0.25d + 0.10d = 10.80 - 15.75
-0.15d = -4.95
d = -4.95/-0.15
d = 33 <=== 33 dimes
q + d = 63
q + 33 = 63
q = 63 - 33
q = 30 <=== 30 quarters
Answer:
11.183 cm and 22.366 cm
Step-by-step explanation:
Lets call the 25 cm hypotenuse C and the other sides A and B.
B=2A
The Pythagorean theorem states that C^2=A^2+B^2 so:
25^2=A^2+B^2
substitute for B
25^2=A^2+(2A)^2
625=A^2+4A^2
625=5A^2
125=A^2
A=11.183 cm
B=22.366 cm
Answer: x=5 and x=-1
Step-by-step explanation:
X^2-4x-5=0
(X-5) (x+1)=0
X-5=0. And. X+1=0
Answer:
Step-by-step explanation:
Fraction of fish ate on first day = 2/6
fraction of fish ate on second day = 2/4
In case of comparison of rational numbers if the numerators of two rational numbers is same and the denominators are different, then the number having larger denominator is less than the number having smaller denominator.
So, the number 2/6 < 2/4
So, the fraction of fish ate on the first day is less than the amount of fish ate on te second day.
It could be square, rectangle, parallelogram, rhombus/diamond but, trapezoid could not be.
