Step-by-step explanation:
(80 x 60) - (60 x 40)
Answer:
B
Step-by-step explanation:
That was actually trickier than I thought it would be
I was looking for 4(x-4), but 4(x-2)(x+2) also works
Answer:
Step-by-step explanation:
A, B & C lie on a straight line.
D, C & E lie on a different straight line.
Ah, this is 2 intersecting lines
angles
y
= 106° and angle
z
= 64°.
well we know that a full size of circle is 360 degrees
let's add z and y :
106+64 = 170
then, let's subtract it from 360
360 - 170 = 90
we must devide it by 2, why? because 90 is from two section of x (2x)
so 90/2 = 45
and there you have it x = 45
if you still cannot visualize what is intersecting line mean, then see the file below
11 miles in 1/4 hour
1/4 of an hour is 15 minutes
so 11 in 15 minutes
x /60 = 11/15
cross multiply
x*15 = 60 * 11
15x = 660
divide both sides by 15
x = 44
the unit rate of the hikers in miles per hour is 44 mph.
You can also solve like this
1/4 of hour is 15 minutes
to get to the whole hour you would multiply by four
so you'd (11miles in 1/4 hour) * 4
44 miles in 1 hour
Hope this helps :)
The name of the shape is an octagon. Since there are 9 identical tiles and you have 72 sides, you would divide 72 by 9 and get 8. And shape that has 8 sides would be an octagon.
