Answer:
82
Step-by-step explanation:
We are given that a graph which shows the number of beads used for varying cord lengths.
The graph

We have to find the number of beads that she can used for cord length 32 in.
Substitute the value x=32
Then, we get

After round to unit place then, we get
y=82
Hence, the best estimate she can used for number of beads =82
Answer: 82
Answer:
Length of the shorter diagonal is 8.68 cm.
Step-by-step explanation:
Length of the side AB = 11 cm
Length of side BC = 5 cm
Angle between these sides, m∠ABC = 50°
By cosine rule in ΔABC,
AC² = AB² + BC² - 2AB.BC.cos B
AC² = (11)² + 5² - 2(11)(5)cos50°
AC² = 121 + 25 - 70.71
AC = √(75.29)
AC = 8.68 cm
By the property of parallelogram,
m∠B + m∠C = 180° [Interior consecutive angles]
50° + m∠C = 180°
m∠C = 130°
Similarly, In ΔBCD,
BD² = BC² + CD² - 2BC.CD.cos130°
BD² = (5)² + (11)² - 2(5)(11)cos130°
BD² = 25 + 121 + 70.71
BD² = 216.71
BD = 14.72 cm
Therefore, length of the shorter diagonal will be 14.72 cm.
1st one: only mentions 1 p wrong
2nd one: saving means (-) cost so this is also wrong
3rd one: how much you owe is x-y and there is no (-) sign in there so it is wrong
the answer is the 4th one because it has p+14%p if p=price and 14%p=14% of p tax
9=9m
Next, what you want to do is divide both sides by m to get the variable.
m=1
Answer:
<h2>12.1% profit</h2>
Step-by-step explanation:
Given data
total eraser= 87
cost =$3 each
Total cost of eraser= 87*3= $261
she sold 63 at $3.5
1. sales made for the 63= $220.5
2 sale made for the remaining= 87-63=24
24*3=$72
Total sales made = 220.5+72=$292.5
her profit= sales-cost
profit= 292.5-261=$31.5
therefore the percent profit is
=31.5/261*100
=0.12*100
=12.1%
