Answer:
Q4) B- he should choose $2000 rebate, 5% equals to 1075
Q5) B- 4
20/5= 4
Check the picture below.
notice, both triangles have a right-angle, so we can use HL on them.
now HL says that if the hypotenuses and one side in each are equal, they are congruent.
well, you can pretty much count how many units for each right off the grid, are the (red) hypotenuses equal?
side CD in green is equal for both since is shared by both anyway.
The gradient is also known as the slope and we can find it using the slope/gradient formula: (y2 - y1) / (x2 - x1)
To find the gradient/slope, we need to first choose two points on the line. You can choose any two points you like, as long as they are on the line you are trying to find the slope of.
Point 1 = (2,2)
Point 2 = (5,8)
Now, we can plug in these points to the formula and solve.
(8 - 2) / (5 - 2)
6 / 3
2
The gradient of the blue line is 2.
Hope this helps!! :)
Answer:
part A 210 Part B 4.4
Step-by-step explanation:
PART A 42 TIMES 5 210
that will be the rate she ran.
PART B 1.1 times 4 that will be the minute.
