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?
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.

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.
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.

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

k = 2.5/1 = 2.5.

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

In triangle JKL, if angle J is seven less than angle L and angle K is 21 less than twice angle L, find the measure of each angle
Answer:
j=45 k=83 L=52
Step-by-step explanation:
j=x-7
k=2x-21
L=x
x-7+2x-21+x=180
4x-28=180
4x=208
x=52
The measure of the angles are; J = 48, K = 57 and L = 75
What is linear pair?Linear pair of angles are produced when two lines intersect each other at a point. The sum of angles of the linear pair is always 180 degrees.
In order to determine the measure of these angles, we have to set J as x. then find the measure of all of these angles.
J = x
K = x + 9
L = 2x - 21
Now, we can add them all together and set equal to 180;
x + x + 9 + 2x - 21 = 180
4x - 12 = 180
4x = 192
x = 48
Now that we have;
J = x = 48
K = x + 9 = 48 + 9 = 57
L = 2x - 21 = 2(48) - 21 = 96 - 21
L = 75
Hence, The measure of the angles are; J = 48, K = 57 and L = 75

describe the effect of change on the area of the rectangle if the base and height are both multiplied by 1/2
Answer:
The area would decrease
Step-by-step explanation:
So if the base was 4ft and the height was 2ft then the area would be 8ft^2. because area is base times height. so if 4 times 1/2 is 2 and 2 time 1/2 is 1 so the area would be 2ft^2
