Answer:
Step-by-step explanation:
a) Percentage of potato filling = 100 - (30 + 25) = 100 - 55 = 45 %
b) Let the number of pies sold = x
45% of x = 90
Number of pies = 200
c) Number of cheese filling = 30% of 200
Number of beef pies = 25% of 200
Difference = 60 - 50 = 10
There are 10 more cheese pies than beef pies.
Answer
y = (1/4)x - 5 or 4y - x + 20 = 0
Explanation
To get the rule required, we interpret the sentence and write it in a mathematical form.
5 less than one fourth of x is y
one fourth of x ⇒ (1/4)x
5 less than one fourth of x is y ⇒ (1/4)x - 5 = y
y = (1/4)x - 5
4y = x - 20
4y - x + 20 = 0
Answer:
-32 m/s
Step-by-step explanation:
Lebron bikes 800 m to the left in 25 seconds.
We are using a coordinate system where rightward is positive.
This means he is moving in the negative axis.
Hence, his displacement is actually -800m.
Velocity is the displacement moved by an object divided by the time spent i.e.
v = d / t
His velocity is therefore:
v = -800 / 25 = -32 m/s
His velocity is -32 m/s.
