Answer:
Part A: <u>Which point represents the origin? </u>
- The origin is the point with both zero coordinates: (0, 0)
Part B: <u>Starting from the origin, explain how to plot the following three points accurately (1,-1) (-1.1.25) (-2,3).</u>
Reference point is the origin for below.
- (1,-1) - go <u>right </u>by 1 unit and <u>down </u>by 1 unit, plot the point
- (-1.1.25)- go <u>left </u>by 1 unit and <u>up </u>by 1.25 or 1 and 1/4 units, plot the point
- (-2,3) - go <u>left </u>by 2 units and <u>up</u> by 3 units and plot the point
Answer: 52.5cm²
Step-by-step explanation:
Firs, you have to split this composite shape into two separate shapes; a rectangle and triangle.
To work out the area of the rectangle you would have to do 8x5=40.
To work out the area you would have to find out the height of it first. So, to do this you would have to do 1+2=3 then do 8-3=5. Now we know the height is 5.
Then you have to use the formula base times height divided by 2 (b×h/2). So 5×5=25 then 25÷2=12.5
To then find the total area of this composite shape you would have to add the two areas together. So 40+12.5=52.5cm²
Hope this helps :)
B) 28×50, then take the answer - 1100
Answer:
5h+5
5(h+1)
Step-by-step explanation:
Equivalent expressions are the ones that look different but are the same. As the statement says that mason works h number of hours during the 5 day week and 5 hours on the weekend, you can write the following expression:
5h+5
h= number of hours Mason works
Then, you can find the common factor to get an equivalent expression:
5(h+1)
According to this, the equivalent expressions are:
5h+5
5(h+1)
