Answer:
9.48*
Step-by-step explanation:
This is a right triangle. The formula for solving the Hypotenuse, or the longest side of the right triangle is A^2 + B^2 = C^2. If we put the numbers from the problem into the formula this is what we get :
3^2 + 9^2 = C^2
9 + 81 = C^2
90 = C^2
9.48 = C
* This is rounded, the exact number is closer to 9.486832980505138. Your class should tell you what to round to.
From the table, the speed of Corinne is given by

From the graph, the speed of Aretha is given by

The distance from the starting point of Corinne at any time t is given by D = 0.125t while the distance from the starting point of Aretha at any time t is given by D = 3.5 + 0.1t
Let t be the number of minutes after the start of the race when Corinne catchs Aretha, then
0.125t = 3.5 + 0.1t
0.025t = 3.5
t = 3.5 / 0.025 = 140
Therefore, the number of <span>minutes after the start of the race that Corinne will catch Aretha</span> is 140 minutes.
Answer: They will be the same after 3 weeks $127
Step-by-step explanation:
Answer:
5 weeks
Step-by-step explanation:
$ 9 an hr for 30 hrs.....(9 * 30) = $270
they deduct $ 27 from her weekly check
so she clears (270 - 27) = $ 243 per week
she wants to get to $ 1200...
1200 / 243 = 4.94 weeks......we are gonna have to round up to 5 weeks because 4 weeks is just a little short.
Anthony ran 5.5 miles each day after school
Let x represent the amount of mile he covered at the park after school. Since he ran 1.5 miles each day before school, the total distance covered each day is:
Total distance covered each day = Distance ran before school + Distance ran after school
Total distance covered each day = 1.5 + x
Since he ran for 4 days in a week, hence:
Total distance ran in a week = 4 days × (1.5 + x)
Total distance ran in a week = 4x + 6
But at the end of the week he ran 28 miles, hence:
4x + 6 = 28
4x = 22
x = 5.5 miles
Hence Anthony ran 5.5 miles each day after school
