Answer:
A. 3/10
Step-by-step explanation:
So the ratio is saying 2 units to 3 units. What represents 1 unit when 1/5 is two units? We cut it in half which is 1/10.
Now we have 1 unit so we can easily find three by multiplying by three, or even just adding three together. So that's 3/10.
let me knowif you don't quite get it.
You’re so smart, I love questions like this. Hopefully you can solve it so I can know too!
Answer:
80 in.²
Step-by-step explanation:
The total surface area of the pyramid is the sum of the area of the base and the areas of the 4 triangular sides.
Square: area = s²
Square: side = 4 in.
Triangular side: area = bh/2
Triangular side: base = 4 in.; height = 8 in.
Area of the base: s² = (4 in.)² = 16 in.²
Total area of the 4 triangular sides: 4 × bh/2 = 2bh = 2 × 4 in. × 8 in. = 64 in.²
Surface area = 16 in.² + 64 in.² = 80 in.²
Answer:
1.28 ÷ 4 = 0.32
But the "models" make little or no sense. I can see the three bars and two dots representing the digits 3 and 2, but that is the only image I see, repeated three times. It also shows no reference to the decimal place, so I would say there is no real representation of it all.
Answer:
C.
Step-by-step explanation:
According to theorem, "the measure of central angle of minor Arc of a circle is doubleto that of the angle subtended by the corresponding major Arc."
So
m<AOB = 2(m<AZB)
m<AZB = M<AOB / 2
m<AZB = 68/2
m<AZB = 34°
