There are a couple ways to determine the number of minutes it will take Charlie to run 9 laps, but the easist would be to find out what is happening to each number of laps in order to get the number of minutes. In each case, the number of laps is being multiplied by 5 to get the number of minutes.
9x5=45 minutes.
He is running each lap in 5 minutes.
Answer:
(x-3)(x-7)
Step-by-step explanation:
Answer:
y=4 mm
Step-by-step explanation:
All angles in a triangle add up to 180: 180=∠M+∠P+∠N, ∠M=180-60-90=30
<u>Use sine rule</u>
a/sinA=b/sinB
PN/sin∠M=PM/sin∠N
y/sin30=8/sin90
y=8/1 *sin30
y=8*0.5
y=4 mm
Answer:
The x-intercept is (-2 1/7, 0).
The y-intercept is (0, -3).
Step-by-step explanation:
To find the y-intercept, substitute x with zero.
To find the x-intercept, substitute y with zero.
Finding the y-intercept by substituting x with zero:
7*0 + 5y = -15
5y = -15
y = -3
The y-intercept is (0, -3).
Finding the x-intercept by substituting y with zero:
7x + 5*0 = -15
7x = -15
x = -15/7
x = -2 1/7
The x-intercept is (-2 1/7, 0).
