Answer:

2 50 mL bottles

Step-by-step explanation:

Find the cost per mL

55 / 80 mL =.6875 per mL

Now find the price of the buy one get one 1/2 off

45 + 1/2 (45) = 45+22.5=67.5

That will be for 50+50 mL

67.5 /100 ml =.675 per mL

The 100 mL is a better deal

Answer:

Two 50 ml bottles.

Step-by-step explanation:

The 80 ml bottle costs £55. That means that you have to pay £55 / 80 per ml of perfume, which is £0.6875.

On the other hand, the 50 ml bottles cost £45. Since it is buy one get one half off, you can do 1.5 * £45 to get the price of both bottles. That would be £67.5 for 100 ml of perfume. You would pay £67.5 / 100 per ml of perfume, which is £0.675.

It is cheaper to get two bottles of 50 ml perfume, so that is the best value for the money.

Hope this helps!

31 and 81 are in the bottom corners of the triangle X is at the top . What is X?

kati45 [8]

Answer:

The top angle of the triangle is, X = 68°.

Step-by-step explanation:

Let there is a triangle named PQR with bottom corner angles ∠ P and ∠ Q and the ∠ R is the angle at the top.

Now, given that ∠ P = 31° and ∠ Q = 81° and we have to find out ∠ R i.e. X.

In Δ PQR, we know, ∠ P + ∠ Q + ∠ R = 180°

⇒ 31° + 81° + X = 180°

⇒ X = 68°

Therefore, the top angle of the triangle is 68°. (Answer)

3x+y=4 2x+y=5 solve using linear combination

Advocard [28]

Idk what linear combination is but you can solve this way:
3x+y=4
-2x-y=-5
x=-1
3(-1)+y=4
-3+y=4
y=7
So x=-1 and y=7

A company donates 2,292 gifts to a school. the gifts are diveded evenly among 19 classrooms. The rest of the gifts are given to

BARSIC [14]

Answer:

Each classroom received 120 gifts and the hospital received 12 gifts

Step-by-step explanation:

Division As Evenly Distribution

The first concept we manage when learning about divisions is how to distribute an amount N among m elements such as everyone receives the same amount.

If the nature of the problem allows distributing decimal portions of N, then every receiver gets exactly the same amount N/m.

But things are different when the division must be an integer number. For example, if we wanted to divide gifts, we cannot give partial gifts. So the correct division is a matter of the study of integer numbers.

If N is divisible by m, i.e. there is no remainder in the division, then each element will receive N/m gifts. But what if they are not divisible? We must divide and take the integer part of the division and discard the remainder

We want to divide 2,292 gifts to the school, where there are 19 classrooms. If we divide 2,292/19 we get 120 and a remainder of 12.

Answer. Each classroom received 120 gifts and the hospital received 12 gifts

Tell whether the relation is a function. {(-5, -3), (-1, 3), (4, 3), (8, 8)}

VladimirAG [237]

Given:

The relation is {(-5, -3), (-1, 3), (4,3), (8, 8)}.

To find:

Whether the given relation is a function or not.

Solution:

A relation is called a function, if there exist a unique output for each input.

We have, a relation given as

{(-5, -3), (-1, 3), (4,3), (8, 8)}

Here, all x-values are different. So, each x-value has a unique y-value.

Thus, there exist a unique output for each input.

Therefore, the given relation is a function.
