Answer:
51% of the money was spent, that is, 51/100. In conclusion, Jemina still has 49/100 of the money available.
Step-by-step explanation:
Since Jemima received $ 5 in pocket money, and spent $ 1.75 on a magazine and $ 0.80 on a drink, to determine the proportion of money he spent and the proportion he has left, the following calculation must be performed:
5 - (1.75 + 0.80) = X
5 - 2.55 = X
2.45 = X
5 = 100
2.55 = X
(2.55 x 100) / 5 = X
255/5 = X
51 = X
Therefore, 51% of the money was spent, that is, 51/100. In conclusion, Jemina still has 49/100 of the money available.
Answer:
1350m
Step-by-step explanation:
Let the distance ran by Denise, Farah and Elaine be D, F and E meters respectively.
From the given information,
D= ⅔(E +F) -----(1)
E= ½(D +F) -----(2)
Let's get rid of the fraction so the equations are much easier to work with.
From (1):
3D= 2(E +F) <em>(Multiply both sides by 3)</em>
3D= 2E +2F -----(3) <em>(</em><em>Expand</em><em>)</em>
From (2):
2E= D +F -----(4)
Substitute (4) into (3):
3D= D +F +2F
3D -D= 3F
2D= 3F
Given that Farah ran 360m, F= 360.
2D= 3(360)
2D= 1080
D= 1080 ÷2
D= 540
2E= D +F
2E= 540 +360
2E= 900
E= 900 ÷2
E= 450
Total distance the 3 girls ran
= D +F +E
= 540 +360 +450
= 1350m
Alternatively, you could start by substituting F= 360 to equations (1) and (2).
AB (y=3) and CD (y=6) are parallel, but different lengths. The figure is a trapezoid. A diagram shows it to be an isosceles trapezoid.
Answer:
x=2 2/3
Step-by-step explanation:
The equation also means that x=8^3
8/3=2 2/3
