Answer:
the 1st 2nd and last one
Step-by-step explanation:
Answer:
X=20
Step-by-step explanation:
The 3 angles all add up to 180º because they are a straight line.
3x + 80 + 2x = 180
5x + 80 = 180
5x + (80-80) = 180-80
5x = 100
5x/5 = 100/5
X=20
Hope this helps!
Answer:
y=-1/4x+2
Step-by-step explanation:
The equation would be y=-1/4x+2 because the rise is -1 and the run is 4 (you could also say the run is -4 and the rise is 1. It doesn't really matter). The line also crosses the y axis at 2, which means that 2 is the y-intercept. :)
Answer:
0.3 with the hat ? the answer is first no, then it's a repeated decimal.
Step-by-step explanation:
Answer:
Part 1) The new dimensions are
base=7.875 cm and height=21.25 cm (see the attached figure)
Part 2) The actual dimensions are
base=1.575 m and height=4.25 m
Step-by-step explanation:
step 1
Find the actual dimensions of the figure
we know that
To find the actual dimensions divide the dimensions on the scale drawing by the scale
The scale is 4 cm/m
base=6.3/4=1.575 m
height=8.5/4=4.25 m
step 2
Make a new scale drawing of this rectangular figure using the scale 5 centimeters = 1 meter
To find the new dimensions on the scale drawing multiply the actual dimensions of the figure by the scale
base=1.575*(5)=7.875 cm
height=4.25*(5)=21.25 cm
see the attached figure of the rectangular figure with the new dimensions
