mother is m years old,and she is 4 times old as her daughter.How much older is mother then daughter.

Answers

Answer:

The mother is 3d older than the daughter

Step-by-step explanation:

Given

Represent the mother's age with m

and

The daughter's age with d

Required

Determine how much older is the mother

First, we need to calculate the mother's age

[tex]m = 4 * d[/tex]

[tex]m = 4d[/tex]

Next, we calculate their age difference

[tex]Age\ Difference = m - d[/tex]

Substitute 4d for m, we have:

[tex]Age\ Difference = 4d - d[/tex]

[tex]Age\ Difference = 3d[/tex]

Hence, the mother is 3d older than the daughter

Krutika and Natasha win some money and share it in the ratio 3:1. Krutika gets £52 more than Natasha. How much did Natasha get?

Answers

Answer:

Step-by-step explanation:

We know that Krutika’s share is three times Natasha’s because they are split in a 3:1 ratio. So we can say:

K=3N

We also know that Krutika’s share is £52 more than Natasha’s:

K= (N+£52)

Substituting what we know about K allows us to reduce the equation to one variable:

3N=N+£52

Clean that up by subtracting N from both sides, leaving us with variables only on one side of the equation.

2N=£52

Which means that we can divide both sides by two to get our answer.

N=£26.

So, of the original £104, Krutika got £78 and Natasha got £26.

Step-by-step explanation:

Those images aren't good enough, I can't really get a good look. Basically, if there are nine little lines between each whole number, then each little line represents a tenth of a whole number, or 0.1. If there are four little lines between each whole number, then each little lines is 0.2. So, you just count up from the whole number below the value. For A, start at 1.0 and count up, each little line is 0.1 (if there are nine lines between each whole number), and figure out where A lies. Hope it helped, wish I could give a definite answer.

7. A recipe for a smoothie calls for 5 cups of strawberries for every 2 cups of bananas. The line represents the relationship between the amount of strawberries and the amount of bananas needed to make a smoothie according to this recipe. The point (1, 2.5) is on the line. Show your reasoning.​

Answers

Answer/Step-by-step explanation:

This is a proportional relationship between amount of strawberries and the amount of bananas needed in making smoothie.

Thus, a constant of proportionality, k, is a ratio that exist between both quantities.

k = y/x = amount of strawberry/amount of bananas.

Since we are given that a recipe of smoothie contains 5 cups of strawberries for every 2 cups of bananas, therefore,

k = ⁵/2 = 2.5.

Any point that will be on the line shown must have the same value of k (y/x).

Thus, given the point (1, 2.5). The ratio between y and x is:

k = 2.5/1 = 2.5.

Since this also shows the same constant of proportionality as 2.5, therefore, the point is also on the line.

Answer/Step-by-step explanation:

This is a proportional relationship between amount of strawberries and the amount of bananas needed in making smoothie.

Thus, a constant of proportionality, k, is a ratio that exist between both quantities.

k = y/x = amount of strawberry/amount of bananas.

Since we are given that a recipe of smoothie contains 5 cups of strawberries for every 2 cups of bananas, therefore,

k = ⁵/2 = 2.5.

Any point that will be on the line shown must have the same value of k (y/x).

Thus, given the point (1, 2.5). The ratio between y and x is:

k = 2.5/1 = 2.5.

Since this also shows the same constant of proportionality as 2.5, therefore, the point is also on the line.
