Answer:
Equivalent fraction: 45/100
Reduced fraction: 9/20
Decimal equivalent: 0.45
Step-by-step explanation:
Equivalent fraction: percentage is just out of 100. 45% is 45 out of 100, aka 45/100.
Reduced fraction is just simplifying both sides by the GCF. In this case, 5.
Decimal equivalent of a percentage is just dividing the numerator by the denominator, or taking the numerator or the percentage and placing the decimal point forward two digits.

Answer:
12 times
Step-by-step explanation:
x is the number of times she has to walk dogs multiplied by 5 dollars she gets each time plus the 25 she started with all equal to 83 because that's how much she needs
5x + 25 = 83
-25 -25
5x = 58
5x/5 = 58/5
x = 11.6
can't walk the dog a 6th of a time so rounded to the nearest while number ti get 12
she has to walk dogs approximately 12 times
Y=Acos(p)+m, A=amplitude, p=period, m=midline, in this case:
A=1/2, p=360(t/12)=30t, m=(10-9)/2+9=9.5 so
h(t)=(1/2)cos(30t)+9.5
