Hello from MrBillDoesMath!
Answer:
9 3/8
Discussion:
2 1/7 = 15/7
4 3/8 = 35/8
so the product
(2 1/7) * ( 4 3/8) =
15/7 * 35/8 =
15/7 * (7 * 5)/8 =
since 35 = 7*5. Cancel "7" in numerator\denominator to get
(15 * 5) / 8 =
75/8 =
9 3/8
Thank you,
MrB
Answer:
Step-by-step explanation:
To do pythagoras theorem
You apply the rules
Which state that,in right angled triangle the square of hypotenus is equal to sum of the square of the other two side. That is
hyp^2=opp^2+adj^2
A= (-4,2)
The x value (-4) stays the same when reflected over the x-axis, so only the y-value gets reflected and therefore changed.
The resultant coordinate is (-4,2)
Answer:
price = x * 0.2
or
price = x * 0.454 * 0.2
Step-by-step explanation:
In this case we must know either the mass of the cake or its volume.
Given the case that we know the mass of the cake, it would be:
price = x * 0.2
where x is the mass of the cake in ounces, that is to say if for example a cake has a mass of 10 ounces, it would be:
price = 10 * 0.2 = 2
which means that each cake costs $ 2
Given the case of the volume, we must first multiply the density by this volume in order to calculate the mass and finally the price.
price = x * 0.454 * 0.2
where x is the volume of the cake in cubic inches, if for example the volume is 10 cubic inches it would be:
price = 10 * 0.454 * 0.2 = 0.908
which means that each cake costs $ 0.9
