Find area on triangle:
A=(1/2)bh
A=(1/2)(8 units)(6 units)
A=(1/2)(48 units^2)
A=24 units^2
Just do the same for the rest of this page following the equation for the area of a triangle A=(1/2)(base)(height)
Find the error:
A=(1/2)bh
100m^2=(1/2)b(20m)
100m^2=(10m)b
10m=b
He forgot to multiply bh by 1/2
Area of parallelogram:
A=bh
A=(3 units)(3 units)
A= 9 units^2
The red line is the height and the bottom of the parallelogram is the base, just count the squares. Imagine cutting the parallelogram at the red line and moving that triangle piece to the other side, it’ll make a rectangle, that’s why the equation is the same.
Answer:
6.00037 x 10^6
Step-by-step explanation:
6000370 in scientific notation
= 6.00037 x 10^6
Answer:I think it’s answer B
Step-by-step explanation:because if you measure figure 2 it will be about 451 and you need it to hold about 300 so it can’t be a or c and figure 3 holds about 321 while figure 1 holds about something so I think it’s B
Answer:
48
Step-by-step explanation:
Answer:
Step-by-step explanation:
Given
Solving (a1): The common difference (d)
d is calculated as
This gives:
Factorize:
Solving (a2): Sum of n terms
This is calculated using:
Substitute values for T1 and d
Factorize:
Solving (b): Sum of first 10.
In this case, n = 10
So:
becomes
