Divide 28 into 2 groups so the ratio is 3 to 4

Mathematics

3     4

3     4

3     4

3     4

Left side gets 12.

Right side gets 16.

12+16=28 in total.

When you're thinking of ratios, you have to think of rounds. Let's say I want to distribute apples... In Round 1, I'm going to give myself 1 apple and give you 2 apples. After Round 1, three apples have been distributed in total. Now, if I repeat the same pattern of distribution 1:2, after Round 2 I should have 2 apples whilst you have 4. After Round 2 a total of 6 apples would have been distributed.If the ratio is 3 to 4 - imagine there are 7 groups total, and one person gets 3 of the 7 and the other person gets 4 of the 7.

____________________________________________
If 28 is divided into 7 groups, each group has 4 cans.

One person gets 3 groups = 4*3 = 12 cans
The other gets 4 groups = 4*4* = 16 cans

This way is easier for me to do, but go with whatever works for you :)

Which equation represents the difference quotient of f(x) for all nonzero values of h?
CaHeK987 [17]

Look at the graph thoroughly .

It passes through origin and given some points

(-1,1)

(1,-1)

(2,-2)

(-2,2)

We observe that

\\ \sf\longmapsto f(x)=-x

Hence whatever the function be the result will be -x

Express these system specifications using the propositions p “The user enters
Alex73 [517]

Answer:

a) r ⋀~p

b)(r⋀p)⟶q

c) ~r ⟶ ~q

d) (~p ⋀r) ⟶q

Step-by-step explanation:

To solve this question we will make use of logic symbols in truth table.

We are told that;

p means "The user enters

a valid password,”

q means “Access is granted,”

r means “The user has paid the

subscription fee”

A) The user has paid the subscription fee, but does not enter a valid

password.”

Fist part of the statement is correct and so it will be "r". Second part of the statement is a negation and will be denoted by ~p. Since both statements are joined together in conjunction, we will use the conjuction symbol in between them which is "⋀" Thus, we have; r ⋀~p

B) Still using logic symbols, we have;

(r⋀p)⟶q

⟶ means q is true when r and p are true.

C) correct symbol is ~r ⟶ ~q

Since both statements are negation of the question. And also, if ~r is true then ~q is also true.

D) Similar to answer A to C above, applying similar conditions, we have (~p ⋀r) ⟶q
