Consider a trapezoid GJKF with:
GH=JH (hypothesis)
FL=KL (hypothesis)
so HL is the median of trapezoid GJKF
so: HL=1/2(2.5+1.2)=1.85
First you need to convert them to the same unit. 1 cm is 10 mm, so the scale is 5:10. 5*2 is 10, so the scale factor is 2.
Answer:
10.54 kg
Step-by-step explanation:
Given that :
Half of blueberries is served with breakfast
The remaining 5270g is served with dinner
How many kilograms of blueberries did the science camp start with :
Total grams of blue berries :
(Grams served at breakfast + grams served at dinner)
Let total blueberries = x
x/2 + 5270 = x
(x + 10540) /2 = x
x + 10540 = 2x
10540 = 2x - x
x = 10540 grams
Amount of kilograms science camp started with = (10540) / 1000 = 10.54 kg
Answer:
x= 90/4*2x
