Answer:
a. 26 units²
Step-by-step explanation:
The x-axis conveniently divides the figure into a triangle (above the x-axis) and a trapezoid (below the x-axis).
The top triangle has a base of 4 and a height of 3, so its area is ...
triangle area = (1/2)(4 units)(3 units) = 6 units²
The bottom trapezoid has a top base of 4, a bottom base of 6, and a height of 4 units. Its area is ...
trapezoid area = (1/2)(b1 +b2)h = (1/2)(4 units + 6 units)(4 units) = 20 units²
The total area of the figure is ...
area = triangle area + trapezoid area = 6 units² + 20 units² = 26 units²
Answer:
No. The 2nd machine makes more!
Step-by-step explanation:
So we want to know whether the two machines are making copies at the same rate. So let's use a ratio.
Machine 1 5 copies: 8 seconds
Machine 2 16 copies: 24 seconds
5:8 and 16:24
try and make them the same.
5:8
16:24
8*3=24
5*3=15
15=16?
no. So the two machines work at different paces.
Answer:
34
Step-by-step explanation:
18 - (-16) double negatives equal a positive so
18 + 16 = 34
Answer: 3, 4
Step-by-step explanation:
and the common factor between these 2 numbers is 1 so 3,4 is its greatest factor
