Answer:
I will answer in a general way because the options are not given.
We know that the area of model A is smaller than the area of model B.
For model A, we have 72 shaded sections, out of 100.
Then the quotient of model A is:
72/100 = 0.72
For model B we have 10 sections, and x shaded ones.
Because model B is greater than model A, we know that:
x/10 should be larger than 72/100
then we have the inequality:
x/10 > 0.72
x > 0.72*10
x > 7.2
And we can not have more than 10 shaded sections (because there is a total of 10 sections) then:
10 ≥ x > 7.2
Then x can be any whole number in that interval.
the possible values of x are:
x = 8
x = 9
x = 10
2x-3y=-15
subtract 2x from each side
-3y = -2x-15
divide by -3
y = 2/3 x +5
this is in slope (2/3) intercept (5) form
If she cut the 4 cheesecakes into 8 even slices then there are 32 slices all together. she gave away 11 slices leaving her with 21. your answer as a mixed number will be 2(5/8)
Note that both 12 and 30 are multiples of 2. Divide the numerator and denominator by 2. 6/15. Note that 6 and 15 are multiples of 3. Divide the numerator and denominator by 3. 2/5. Note that 2 and 5 are both prime numbers. Your answer is 2/5.
The Formula would be A=3.14rr
Which is A=3.14(3)(3)
The answer is 28.26
