Answer:
To the nearest tenth, the length is 6.4 meters, and the width is 3.4 meters.
Step-by-step explanation:
Let w be the width of the rectangle. Then l = w + 3, and we have:
[tex] w(w + 3) = 22[/tex]
[tex] {w}^{2} + 3w = 22[/tex]
[tex] {w}^{2} + 3w - 22 = 0[/tex]
Calculating the discriminant:
[tex] \sqrt{ {3}^{2} - 4(1)( - 22)} = \sqrt{9 + 88} = \sqrt{97} [/tex]
So by the quadratic formula, and discarding the negative solution, we then obtain:
[tex]w = \frac{ - 3 + \sqrt{97} }{2} = 3.4[/tex]
[tex]l = w + 3 = 3.4 + 3 = 6.4[/tex]

suppose there is a 1.2°F drop in temperature for every thousand feet that an airplane climbs into the sky. if the temperature on the ground is 56.9°F, what will be the temperature when the plane reaches an altitude of 8,000 ft?
We have a linear model, that relates temperature with altitude.
The first senctence gives us a clue about tha rate of change (the slope) of temperature in function of the altitude.
We can write the slope, in °F/1000 ft, as:
[tex]m=-1.2[/tex]The temperature on the ground, where h=0, is 56.9 °F, so we can write the equation of the line as:
[tex]T(h)=-1.2h+56.9[/tex]When the altitude is 8,000 ft, h=8 and T is:
[tex]T(8)=-1.2\cdot8+56.9=-9.6+56.9=47.3[/tex]The temperature at 8,000 ft will be 47.3 °F.

17. P(-6, 16), Q(2, -4), R(-6, 14), S(-2, 4)Slope of PQ Slope of RSTypes of Lines
The formula for finding slope is expressed as
slope = (y2 - y1)/(x2 - x1)
where
y2 and y1 are final and initial values of the y coordinates respectively
x2 and x1 are final and initial values of the x coordinates respectively
Considering line PQ,
x1 = - 6, y1 = 16
x2 = 2, y2 = - 4
Slope = (- 4 - 16)/(2 - - 6) = - 20/8
Slope = - 2.5
Considering line RS,
x1 = - 6, y1 = 14
x2 = - 2, y2 = 4
Slope = (4 - 14)/(- 2 - - 6) = - 10/4
Slope = - 2.5
If the slope of two lines are equal, it means that they are parallel. We can see that the slopes of PQ and RS are equal. Thus,
Line PQ is parallel to line RS

Katie’s hair is 4 ½ x + 1 inches long. She decides to get a haircut. The barber cuts ¼ x – 2 inches off her hair. Write an expression that would represent how long Katie’s hair is when she leaves the barbershop, if simplified.
Katie's hair is (17x/4 +3) inches long when she leaves the barber shop.
According to the question,
We have the following information:
Katie’s hair is 4 ½ x + 1 inches long.
The barber cuts ¼ x – 2 inches off her hair.
Now, the remaining length of her hair will be obtained by subtracting the length of hair cut from the original length.
So, we have the following expression:
([tex]4\frac{1}{2} x+1[/tex])-(x/4-2)
9x/2+1-x/4+2
9x/2-x/4+3
Taking 4 as the least common factor:
18x-x+12/4
17x+12/4
17x/4 + 12/4
17x/4 + 3 inches
Hence, Katie's hair is (17x/4 +3) inches long when she leaves the barber shop.

A small publishing company is planning to publish a new book. The production costs will include one-time fixed costs (such as editing) and variable costs (suchas printing). The one-time fixed costs will total $30456. The variable costs will be $10 per book. The publisher will sell the finished product to bookstores at aprice of $21.75 per book. How many books must the publisher produce and sell so that the production costs will equal the money from sales?
Let x be the number of books that need to be sold, then for the cost of the production and the profit to be the same we can set the following equation:
[tex]30456+10x=21.75x\text{.}[/tex]Subtracting 10x from both sides of the equation we get:

What is the equation of the line in slope-intercept form?
Answer:
5/2; 5
Step-by-step explanation:
The first box is m, which is the slope. To find the slope you do rise over run, so basically the change in x and y. You move up 5 and over 2, so m would be 5/2.
The second box is b, which is the y-intercept. To find the y-intercept, you just find where the line crosses the y-axis. That would be 5

What do we mean by the congruency of triangles?Two triangles are said to be congruent if all three corresponding sides and all three corresponding angles have the same size.
You can move, flip, twist, and turn these triangles to produce the same effect.
So, first label the two triangles as △ABC and △ADE.
Now, to prove that △ABC ≅ △ADE:
BA = DA (Given)
AC = ED (Given)
∠BAC = ∠ADE (Since, both lines are similar, so the angle between them will also be soililar and congruent.

Joanne cannot decide which of two washing machines to buy. The selling price of each is $390. The first is marked down by 40%. The second is marked down by 10% with an additional 30% off. Find the sale price of each washing machine. Use pencil and paper. Explain why Joanne should buy the first washing machine rather than the second if the machines are the same except for the selling price.
Answer:
Joanne should definitely purchase the first one because it is much cheaper.
Step-by-step explanation:
So, to find the cost of each washing machine, we can simply turn the percentages into decimals and multiply to get our answer. Let's start with 40%. We bring the decimal back to spaces to get: 0.40. Then, we multiply it from the $390, because 40% 'of' means multiply:
0.40 x 390 = $156.
390 - 156 = $234
Now, the next one:
0.10 x 390 = $39
390 - 39 = $351
Then, we take 351 dollars and find the 30% off difference.
0.30 x 351 = 105.30
390 - 105.3 = $284.70
