Answer:
Step-by-step explanation:
surface area of sphere=a
4pir^2=a
r^2=a/4p
r=root(a/4pi)
if radius is doubled
r1=2root(a/4pi)
r1^2=4(a/4pi)
a/a1=(4pia/4pi)/(4pi 4a/4pi)=1/4
so a is increased by 4 times
The answer is Translation since the shape never changed any angle or position it is safe to say that they just used a translation to move it.
Answer: right of the picture
Step-by-step explanation:
The answer would be 408 if u take 340 and divide it by 10, then you get 34 and times it by 12
Answer:
(a) 60 cups
(b) 5 cookies, 8 muffins and 4 cupcakes in each container
Step-by-step explanation:
Given
Let:

So:

Solving (a): The greatest number of containers to be used;
To do this, we first reduce the ratio to the lowest
C : M : K = 300 : 480 : 240
Divide by 60

<em>The ratio cannot be further reduced. Hence, he will use 60 cups</em>
Solving (b): The number in each cup
In (a), we have:

This means that;
<em />
<em> --- Cookies</em>
<em />
<em> --- Muffins</em>
<em />
<em> -- - Cupcakes</em>
