Answer:

B. 203.403

Step-by-step explanation:

2 times 100 = 200

3 times 1 = 3

4 times 1/10 = 0.4

3 times 1/1000 = 0.003

200 + 3 = 203

203 + 0.4 = 203.4

203.4 + 0.003 = 203.403

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

y=2.52x+1.61

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

y=2.52(32)+1.61=82.25

After round to unit place then, we get

y=82

Hence, the best estimate she can used  for number of beads =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

Bad White [126]

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%
