Answer:
B. 48m²
Step-by-step explanation:
The formula for volume is length (base) times width times height, or LWH. If you break the shape into three separate areas, you can figure out the volume for each part and then add it up.
The large part on the bottom is 7m long, 2m across. Since we know the entire shape is 4m tall and the indent is 2m deep, we know that the height for the bottom part will also be 2m. <u>7 · 2 · 2 = 28.</u>
The block on the left is 2m tall, 2m across, and its width is also 2m as shown by the measurement on the bottom-right. <u>2 · 2 · 2 = 8.</u>
Finally, the block on the right is 2m tall, 3m across, with a width of 2m. <u>3 · 2 · 2 = 12.</u> And when you add it all up, <u>28 + 8 + 12 = 48.</u> Hope this helps! Feel free to ask any questions!

Answer:
given (0,0) and (12,y1)
the distance formula states taht
the distance between the points (x1,y1) and (x2,y2) is
D=
given
D=13
x1=0, y1=0
x2=12
square both sides
minus 144 both sides
sqrt both sides
+/-5=y2
the points are
(12,5) and (12,-5)
Step-by-step explanation:
Answer:
210 pupils
70 girls
Step-by-step explanation:
1/3 are girls ,it means that the number of boys are 2/3
3/3-1/3=2/3
2/3 when multiplying we do change to 3/2
3/3 x 140 x 3/2=210 pupils
1/3 x 210=70
