Answer:
300 masks
Step-by-step explanation:
If 267 is 89% of the whole amount, we can set up the following proportion:
, where x is the total amount of masks we need to find.
If we cross-multiply, we get 26700=89x. Divide both sides by 89, and we get 300. So, Cameron has a total of 300 masks in his collection.
I hope this helped.
Answer:
£1290
Step-by-step explanation:
35%+40%= 75%
£600=25% £600÷20=30 25%of till = 30 notes 100%=120 notes
40% of 120 =48notes 48x10=£480
90notes-48notes=42notes
42x£5=£210
£600+£480+£210=£1290
<span>To link the displayed Wright flyer in the museum with the
actual plane, we have to calculate for the relation of the corresponding
parameter. In this problem, for both the display and the actual plane, we are
given with the length. Computing for the ratio gives us,</span>
<span>
ratio = length of the model / length of the actual plane
Length of the model = 35 cm</span>
<span>
We need to calculate for the length of the model in ft.</span>
<span>
length of the model = (35 cm)(1 in/2.54 cm)(1 ft/12 in)
length of the model = 1.148 ft
</span>
<span>
</span>
<span>Going back to the calculation for the ratio,
ratio = (1.148 ft)/21 ft
ratio = 0.055
Therefore, the measurements used in the model is equal to 0.055 times the
actual dimensions.
Error may occur because of the number of significant figures measured for
rounding up or down of the answers after each calculation. </span>
