Give an example of a proportion that uses the numbers 2, 3, 4 and 6.
2:3 is the same as 4:6
Proportion says that two ratios (or fractions) are equal.
Answer:
62 Kg
Step-by-step explanation:
Let g = weight of Grok last year in kg
m = weight of Grok's mother last year in kg
m = 3g
m-4 = 2(g+9)
since m = 3g
(3g)-4 = 2(g+9)
3g -4 = 2g + 18
3g-2g = 18+4
g = 22
m = 3*22
= 66
Note that:
g+9 = weight of Grok now
m-4 = weight of Grok's mother now
Grok weighs 31 Kg now
Grok's mother weighs 62 Kg now
Let's make two expressions.
4.92+3.79x
This represents the car service's cost, which x being miles.
4.2x
This is the most Jason wants to spend. Let's make them equal.
4.92+3.79x=4.2x
We need to get x by itself, Let subtract 3.79x from both sides.
4.92=0.41x
Let's divide.
4.92÷0.41=12
So, he should not drive no more than 12 miles.
In a kite, there is always an angle that is not right, otherwise, it would have a rectangular shape.
The diagonals are not of the same length because that would mean it would have a rectangular shape as well.
The sides are not equal, because that would mean it would have a rhomboid shape, to which a square belongs to.
The top edges are congruent with each other, as well as the bottom ones. This is because you can turn one into the other by reflecting them using an isometry, so D is true.
