Answer:
$70.47
Step-by-step explanation:
Since the cost of the aquarium with the 15% discount is $59.90 then $59.90 is 85% of the original price. Remember 100-15=785. To find the original price set up a proportion with these values:
Solve for the original price by cross multiplying numerator with denominator.
x(85) = 59.90(100)
85x = 5990
x= $70.47
Answer:
Step-by-step explanation:
<u>Prime Factors</u>
The first prime numbers are:
{1,3,5,7,11,13,...}
To find the prime factors of any integer number, we successively divide the number by all the possible prime numbers, probably more than once.
Let's find the prime factors of 1400.
Dividing by 2 while possible:
1400/2 = 700
700/2 = 350
350/2 = 175
3 is not a divisor of 175, so we try 5:
175/5 = 35
35/5 = 7
Since the last result is a prime number, no more tries are necessary. The product of prime factors in index form is:
So what you do first is find the area of this lawn and you do 10 by 12 and multiply those and you get 120 feet so now what you do is divived 120 by 3 and you get 40 so that means she mowed 40 ft in each hour so that would be the unit rate.
Answer:
x= -5 or -1
Step-by-step explanation:
subst y = -x + 5 into y = x^2 + 5x + 10
-x +5 = x^2 + 5x +10
x^2 +6x +5 = 0
(x+5)(x+1)=0
x= -5 or -1
