Answer:
23.12
Step-by-step explanation:
When you multiply by the two decimals count how many places(numbers) are behind each decimal for a number and add for both of them
For Example
3.4-> There is one place (Number) behind the decimal.
x 6.8 -> there is one place(Number) behind the decimal add how many numbers behind the decimal from both numbers 23.12-> since there are 2 Numbers/ places behind the decimal in the numbers multiplied you move the decimal 2 places / Numbers In the product.
You are looking for a speed in miles per hour, so start by converting 90 minutes into hours.
90/60 = 1.5
90 minutes = 1.5 hours
speed = distance/time = (105 miles)/(1.5 hours) = 70 mph
The greatest common factor 27+36=63 is 9 times 7
15%=3
5%=1
5(20)=100
1(20)=20
So, there are 20 students in the class.
Answer:
C. one solution
Step-by-step explanation:
The number of solutions can be found from the number of intersection points.
There are 2 lines, a parabola (curve) and a horizontal line that is parallel to the x axis.
We see that there is 1 point of intersection between the 2 lines, at (2,1)-right 2 and up 1. Therefore, this non linear system has 1 solution.
C. one solution is the correct answer.
