Answer:
Step-by-step explanation:
To get from blue to red you need to multiply the blue dimensions by 1.5.
4*x = 6 Divide by 4
x = 6/4
x = 1.5
The surface area is a different ball game.
SA of the blue figure
Surface area of 1 side = 4 * 4 = 16
The total surface area = 16* 6 = 96
SA of the red figure
Surface area of 1 face = 6*6
Surface area of 6 faces = 6 * 36 = 216
So what's the ratio ?
Ratio = red surface area/ blue surface area
Ratio = 216 / 96 = 2.25
Notice that if you square the dimensional ratio, you get the area ratio
1.5^2 = 2.25
Answer:
h < 2
Step-by-step explanation:
Step 1: Distribute
10h + 40 < 60
Step 2: Subtract 40 on both sides
10h < 20
Step 3: Divide both sides by 10
h < 2
The answer is 30.
8 x 5 =40
40 - 10 = 30
Answer:
(a) 3 ft, 4 ft, 5 ft
Step-by-step explanation:
The triangle inequality requires the sum of the two short sides exceed the long side.
__
a) 3 ft + 4 ft = 7 ft > 5 ft . . . . . triangle is possible
b) 4 yd + 1 2/3 yd = 5 2/3 yd < 10 yd . . . . not a possible triangle
c) 3 ft + 3 ft = 6 ft < 7 ft . . . . not a possible triangle
d) 4 in + 4 in = 8 in . . . . not a possible triangle (not greater than 8 in)
__
The first set of side lengths can form a triangle: 3 ft, 4 ft, 5 ft.
i dont understand the question?
