Answer:
T = 0.34r³
Step-by-step explanation:
Given that T is directly proportional to r³ then the equation relating them is
T = kr³ ← k is the constant of variation
To find k use the condition T = 21.76 when r = 4 , then
21.76 = k × 4³ = 64k ( divide both sides by 64 )
0.34 = k
T= 0.34r³ ← equation of variation
Answer:
y = 11, x = 76/6
Step-by-step explanation:
We will start by finding y
92 + 8y = 180 we know this because the angle degree of one line is 180 you can just do simple elimination to solve this
92+ 8y = 180 subtract 92 from both sides
8y = 88 then divide both sides by 8 and you get
y = 11
Now for x we know the blank angle is equal to 88 because of vertical angles
so now it is 88 + ( 6x - 16) = 180 again we do elimination
88 + 6x - 16 = 180 subtract 88 from both sides and you get
6x - 16 = 92 then subtract 16
6x = 76 then divide both sides by 6 and get
hope this helps :)
Answer:

Only 1 flavour ??anyway ....number of different ice cream desserts
desserts= 3 x 1 x 4
= 12
To solve the question we need to note that:
area scale factor=(linear scale factor)^2
linear scale factor=1:2:3
Area scale factor=1^2:2^2:3^2=1:4:9
Hence, given that the area of the smallest triangle is 72 sq. inches, the area of:
medium triangle will be:
4/1*72=288 sq. inches
largest triangle will be:
9/1*72=649 sq. inches
