your drapery business has just gotten a new client who needs 4 drapes. each one will need to be 8 feet by 5 feet and you must add an additional 6 inches on top and bottom for a hem. the customer has chosen the fabric but the store only has 6 linear yards of material. is that enough to make all the drapes? why or why not?

Answers

1. You have that:

- The new client who needs 4 drapes.
- Each dreape will need to be 8 feet by 5 feet. Therefore, the perimeter will be:

P1=8 ft+8 ft+5 ft+5 ft
P1=26 ft

- You must add an additional 6 inches on top and bottom. Therfore, the perimeter will be:

1 inch=0.0833 ft
6 inches=0.499 ft≈0.50 ft

P2= 2(0.50 ft++0.50 ft+8 ft+8 ft)
P2=34 ft

- Thefore, the total perimeter of the drape will be:

Pt=26 ft+34 ft
Pt=60 ft

- The perimeter of 4 drapes will be:

=60 ftx4
=240 ft

- The problem says that the store only has 6 linear yards of material. Therefore:

6 yards=18 ft

The answer is: It is not enough to make all drapes, because you need 240 ft of material and the store only has 18 ft.

Solve by using the perfect squares method.x2 + 16x + 64= 0
a. –8
b. –16
c. 8
d. 16

Answers

x² + 16x + 64 = 0
x² + 2 * x * 8 + 8² = 0

Now, sing the formula (a + b)² = a² + 2ab + b² , we get,

(x + 8)² = 0

Square rooting on both sides, we get,

x + 8 = √0

x + 8 = 0

x = - 8 <== that's your answer!!!

x²+16x+64=(x+8)² (because (a+b)²=a²+2ab+b² => perfect square)
So you have to find x which will make (x+8)²=0
which is true when x+8=0
x=-8
That's a.
Hope it helps!

The data below were gathered on a random sample of 5 basking sharks, swimming through the water and filter-feeding, i.e. letting the water bring food into their mouths.Body Length (meters) Column 1

Mean Speed (meters/seconds) Column 2

4 0.89
4.5 0.83
4 0.76
6.5 0.94
5.5 0.94

Construct a scatterplot of the data and answer the following questions:
(a) What is the label for the horizontal axis?
(b) What is the label for the vertical axis?
(c) Interpret the scatterplot (comment on association, form, strength, and outliers).

Answers

Given:
Body length (meters) Mean Speed (meters/seconds) 4 0.89
4.5 0.83 4 0.76 6.5 0.94 5.5 0.94

The horizontal axis is the x-axis. The values reflected in this axis is the body length of the shark.

The vertical axis is the y-axis. The values reflected in this axis is the mean speed.

Graph your own scatter plot.
point 1 (4, 0.89)
point 2 (4.5, 0.83)
point 3 (4, 0.76)
point 4 ( 6.5, 0.94)
point 5 (5.5, 0.94)

The correct answers are:

Body length; Mean Speed; There appear to be no outliers, the graph seems to have a strong positive association and appears to be nearly linear in form. The graph is attached.

Explanation:

Since body length is in column 1, that will be the label of the horizontal axis. The mean speed is in column 2, so that will be the label of the vertical axis.

The points are very tightly grouped and appear to be slightly increasing. There are no points that are very different than the rest, so there are no outliers.
