Mathematics
1 answer:
avanturin [10]4 years ago
8 0

Answer:

b=\dfrac{1}{5}a.

Step-by-step explanation:

We need to write an  equation for the amount of chemical B as a function of the amount of chemical A.

b=f(a)

b\propto a

b=ka     ...(1)

where, k is constant of proportionality.

It is given that fifteen grams of chemical A is used to produce 3 grams of chemical B. It means a=15 and b=3.

Substitute a=15 and b=3 in (1).

3=k(15)

k=\dfrac{3}{15}=\dfrac{1}{5}

Substitute k=\dfrac{1}{5} in (1).

b=\dfrac{1}{5}a

Therefore, the required function is b=\dfrac{1}{5}a.

Jacob is mixing salt with
77julia77 [94]

The number of tablespoons of salt jacob mixes with 1 cup of water is 4 tablespoon of salt.

<h3>How to interpret the division? </h3>

When 'a' is divided by 'b', then the result we get from the division is the part of 'a' that each one of 'b' items will get.

Thus, if 10 mangoes are there, and 2 people, then 10 ÷ 2 is the number of mangoes each person would get, which is 5.

Division, thus, can be interpreted as equally dividing the number that is being divided in total x parts, where x is the number of parts the given number is divided.

Thus, a \div b = a divided in b equal parts.

Also, we can write: a \div b = a \times \dfrac{1}{b}

(it is since a = a times 1 so a/b = 1 \times (a/b) = (1/b) \times a)

The given table is:

Tablespoons of salt          Cups of water

             8                                    2

             16                                   4

             24                                   6

2 cups of water gets 8 tablespoon of salt.

Then 1 cup of water gets 8/2 = 4 tablespoons of salt. (divided the numbre of cups of water and number of tablespoons of salts in 2 equal parts).

This pattern remains same for other rows of the table, since we have:

1 cup of water gets 8/2 = 16/4 = 24/6 = 4 tablespoons of salt.

Thus, the number of tablespoons of salt jacob mixes with 1 cup of water is 4 tablespoon of salt.

Step-by-step explanation:

The error is in Step 1, by not adding 2 on the left side, that is

Given

7.7 = w - 2 ( add 2 to both sides )

7.7 + 2 = w - 2 + 2

9.7 = w
