Answer:
The surface area of the red sphere is 452.4 cm²
Step-by-step explanation:
The question here is easy to calculate provided you understand it and apply the formula necessary for deriving the answer and it says that two spheres are similar. The surface area of the blue sphere is 9160.9 square centimeters with a radius of 27cm. What is the surface area of the red sphere with a radius of 6cm
Surface area of a sphere is given as 4 × pi × r²
And if we have he radius as 6 cm,we can then input the figured so as to get the surface area of this sphere.
Remember that pi= 22/7 or 3.142
4 × 22/7 × 6² = 452.4 cm²
1. 45
write the consecutive numbers as x, x+1 and x+2 as its a sum 3x+3=138 so 3x+135 and x=45
2.$4
27-3=24, 6 candy bars for $24 dollars so $4 each
3. 6 hours
59-11 initial fee is $48 at a rate of $8 per hour, 48/8 is 6hours
4.52
29 is half of what he had once getting 6 new cards
so 58-6 52 giving the original number
5.27
using the same method as 1
6.21
odd numbers must be written as 2n+1,2n+3,2n+5
the sum 6n+9 =69
n=10
2n+1=21
7. 12
12-6 =6
6x2=12
8.$6
12-9=3
this is half the allowance so the is 3x2=6
9.57
291-6=285 is the number in all 5 buses total
285/5=57 students per bus
10.19
184-13= 171 dollars spent on all nine books
171/9=19 per book
Answer:
The answer you are looking for is B) Function only.
Step-by-step explanation:
A function graph would mean that each x value corresponds to one y value, in a function multiple x values can have the same output but one x value cannot have more than one output.
A relative graph means each x value has their own unique output value and each x value (f(x)) has one output but cannot share that output with any other x value.
In this case x=5 which means it can only be a function.
Hope this helps!
