Step-by-step explanation:
Answer:
should be left in the candy bar.
Step-by-step explanation:
Jenn and David shared a candy bar. Let's assume the bar was split into 10 parts, since 10 is the denominator of the fraction.
First, we need to add how much that the candy bar was eaten so we can subtract easier.
Jenn ate three tenths.
David ate four tenths.
So, seven tenths of the candy bar was eaten. We need to subtract that from a whole, because we need to know how much candy is left.
So, there are 3/10, or 0.3, of the candy bar left to share later.
Okay,
So we know how many pizzas they sold throughout the week, we add those together.
93

405
You divide "405" by the amount of numbers there are.
so "5" into "405"
5 goes into 40 8 times
now we have 5 into 5 which goes 1 time.
Our answer is a solid 81.
To check our work, we can multiply 81 by 5.
5*1=5
5*8=40
405.
A. 81 is your answer
Let the width be x, then length = 4x - 7
Perimeter = 2(length + width)
2(x + 4x - 7) = 46
2(5x - 7) = 46
10x - 14 = 46
10x = 60
x = 6
Therefore, width is 6 and length is 4(6) - 7 = 24 - 7 = 17
We can find x only if we know that the figure is a REGULAR octagon, i.e. an octagon with all sides equal, and all interior angles equal.
We will ASSUME that the figure is a regular octagon.
For a regular polygon, the central angle subtended by each side is equal.
The central angle is 360 degrees.
So the central angle subtended by a single side euqals
a=360 degrees / 8 sides = 45 degrees / side
Since x is the total angle subtended by three sides, so
x=3*45=135 °
