378x6 using place value with regrouping. 378 x 6 as (300 x 6) + (70 x 6) + (8 x 6) = 1800 + 420 + 48 = 2268.
Answer:
<em>a) She started walking back</em>
<em>b) 0.13 km/min</em>
Step-by-step explanation:
The graph shows the distance traveled by Jo. She starts her journey (t=0) at a distance of 0 Km since the graph passes through the origin (0,0).
a) Ten minutes later she is at a distance of 1 km from the starting point and then the distance starts to drop. This means that at t=10 minutes, she started walking back.
b) To calculate the speed for the last 30 minutes of journey, we find the slope of the line. Select the points (30,0) and (60,4).
If a given line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:
Substituting:
v=0.13 km/min
a.)0.4 is the multiplier
b.)$32 after 1 year, $2.048(or $2.05) after 4 years
c.)V(t) = 80(0.4)t
d.)10 years because it will be below 2 cents
e.) [The graph isn't hard, you just have to plug in the numbers into y=80(0.4)^x]
The missing angle is also 111 since they’re opposite interior angles (and are equal).
Yes, the Y values are being multiplied
