Answer:
$8.25
Step-by-step explanation:
1.25+(2.25x2)+1.00+(1.25x2)=8.25
Answer:
(-2, 1)
Step-by-step explanation:
consider the following equations: -x-y=1 y=x+3
For the lines to intersect, the values must be the same
-x-y=1
x + y = -1
y = -x - 1
Equating the y values
-x - 1 = x+ 3
-x-x = 3 + 1
-2x = 4
x = 4/-2
x = -2
Substitute x = -2 into y = x+3
y = -2 + 3
y = 1
Hence the required coordinate is (-2, 1)
Answer:115 apex
Step-by-step explanation:
Answer:
9/25
Step-by-step explanation:
Two pyramids are similar. Their base edges are a ratio of 3:5. Find the ratio of their surface area.
The ratio of the surface area is calculated as the square of the ratio of the edges
Hence,
Ration of surface area = 3²/5²
= 9/25
