Answer:
25:)
Step-by-step explanation:
To solve this, we first have to find an individual rate:
3/5
4/7
For the first one:
1 lap in 5/3 minutes
Second one:
1 lap in 7/4 minutes
find a common LCD
5/3 and 7/4
20/12 and 21/12
4 laps in 7 minutes is faster
Just multiply -2 by 2 and multiply that answer by 2 until the chart is complete on the right side. Basically the same thing for the right side just add
Answer:
Length of the segment QS = 11.76 cm
Step-by-step explanation:
We are given with right angle triangle QRS
Angle S is 80 degree and RS = 2 cm
We need to find out QS
RS is adjacent to angle S, so we use cos formula
Plug in the angle and RS
Given cos(80) = 0.17
Multiply by QS on both sides
0.17 * QS = 2
Divide by 0.17 on both sides
QS= 11.76470588
Length of the segment QS = 11.76 cm
Answer:
I think the answer is m= -1/3 b=7/3
Explanation:
so first, you need to make equations using the info that the question gave.
f(-2)= m(-2)+b f(4)= m(4)+b
= -2m+b =4m+b
f(-2)= 3 f(4)= 1
-2m+b= 3 4m+b=1 -(2)
b= 3+2m -(1)
substitute (1) into (2) : 4m+(3+2m)=1
4m+2m+3=1
6m=1-3
6m= -2
m= -2/6
m= -1/3
Substitute m= -1/3 into (2)
4(-1/3) + b=1
-4/3 +b =1
b= 1+ 4/3
b= 7/3
Therefore, m= -1/3 b=7/3
and that's how you do it
