Answer: Yes

Tc = 3.12m

Therefore, total cost of apple is directly proportional to the total mass with a proportionality constant of 3.12.

Step-by-step explanation:

The total cost of the apples is proportional to the total mass. The product of the mass and the cost per mass ($3.12) gives the total cost.

It can be shown using the equation below

Tc = c×m

Where Tc = total cost

c = cost per unit mass

m = total mass in kilogram

Tc = 3.12m

Therefore, total cost of apple is directly proportional to the total mass with a proportionality constant of 3.12.

Why do you think triangles and math are important and bridges you must use proper math terms and provide your reason as wide tri

Makovka662 [10]

Well, from triangles we derive trigonometry which can be use to construct bridges, for example, if we want to construct a bridge using some kind of support belief it, it’ll probably be a triangular structure cause it supports more stability

Can you help me on this question 6(r-8)=8r-36

erastova [34]

Answer:

r = -6

Step-by-step explanation:

6(r - 8) = 8r - 36

distribute 6 into r - 8

6r - 48 = 8r - 36

add 36 to both sides

6r - 12 = 8r

subtract 6r from both sides

-12 = 2r

divide by 2 on both sides

-6 = r

What is magnitude in maths ?

blondinia [14]

Answer:

In mathematics, the magnitude or size of a mathematical object is a property which determines whether the object is larger or smaller than other objects of the same kind. More formally, an object's magnitude is the displayed result of an ordering ( or ranking ) - of the class of objects to which it belongs.

List all subsets of ta, b, c, d, e) containing a but not containing b

fomenos

Answer:

(a), (a,c), (a,d), (a,e), (a,c,d), (a,c,e), (a,d,e), (a,c,d,e)

Step-by-step explanation:

We are given the set (a,b,c,d,e).

Total number of subsets of the above set are $2^5$ = 32

Subsets:

(a,b,c,d,e)

(a), (b), (c), (d), (e)

(a,b), (a,c), (a,d), (a,e), (b,c), (b,d), (b,e), (c,d), (c,e), (d,e)

(a,b,c), (a,b,d), (a,b,e), (a,c,d), (a,c,e), (a,d,e), ( b,c,d), (b,c,e), (b,d,e), (c,d,e)

(a,b,c,d), (a,b,c,e), (a,b,d,e), (a,c,d,e), (b,c,d,e)

Subset having a but not b :

(a), (a,c), (a,d), (a,e), (a,c,d), (a,c,e), (a,d,e), (a,c,d,e)
