12. The length and width of a rectangle are in the ratio 7:3. If the perimeter is 62cm calculate: (1) the width (ii) the length of a diagonal to the nearest centimetre. (iii) the area of the rectangle.
Answer:
Step-by-step explanation:
Length = 7x
Width = 3x
Perimeter = 2L + 2W
Part A
2*7x + 2*3x = 62
14x + 6x = 62
20x = 62
x = 62/20
x = 3.1
Length = 3.1 * 7 21.7
Width = 3.1 *3 9.3
Width = 9.3
Part B
Use the Pythagorean Theorem
diagonal squared = 21.7^2 + 9.3^2
diagonal^2 = 557.38
sqrt(diagonal^2) = sqrt(557.38)
diagonal = 23.61
To the nearest cm is 24
Part C
Area = L*W
Area = 21.7 * 9.3
Area = 201.8
Find the value of x in the isosceles triangle shown below.
Answer:
22.18 = x
Step-by-step explanation:
a^2 + (b)^2 = (x/2)^2
a = sqrt(74)
b = 7
x/2 = ?
(74)[^1/2]^2 = 74
b^2 = 7^2 = 49
74 + 49 = (x/2)^2 Substitute into a^2 + b^2 = c^2
123 = (x/2)^2 Combine like terms
(123^0.5) = x/2 Take the square root of both sides.
11.09 = x/2 Multiply both sides by 2
11.09*2 = x
22.18 = x The full length of the base of the triangle is 22.18
Answer: C
Step-by-step explanation: We only need to find the value of one of the x so just use Pythagorean theorem but simplified to do it in one step which is sqrt(4^2+6^2) which gives us sqrt(52).

Doug bought a new car for $25,000. He estimates his car will depreciate, or lose value, at a rate of 20% per year. The value of his car is modeled by the equation V = P(1 – r)t, where V is the value of the car, P is the price he paid, r is the annual rate of depreciation, and t is the number of years he has owned the car. According to the model, what will be the approximate value of his car after 4 and one-half years?
$2,500
$9,159
$22,827
$23,791
Answer:
Step-by-step explanation:
The equation actually looks like this
[tex]V=P(1-r)^t[/tex] and filling in the info given:
[tex]V=25,000(1-.2)^{4.5[/tex] which simplifies to
[tex]V=25,000(.8)^{4.5[/tex]
Orders of operation tells us that we need to take care of the exponential stuff first, so
V = 25,000(.3663573) and
V = $9158.93 which rounds to what is shown as the second choice down: $9,159.

The length of a rectangle is twice its width. If the area of the rectangle is
32cm2, find the perimeter.
Before we find the perimeter, first we must know length and width.
Let width = x
The question says that the length of a rectangle is twice its width. Therefore the length is 2×x or two times of width which equal to 2x.
The area of rectangle is given as 32 cm^2.
Do you remember the rectangle area formula? If not then it is:
[tex] \large \boxed{ \tt{A = width \times length}}[/tex]
Since A is area - substitute A = 32 in. As for width, we substitute in x and length in 2x.
[tex] \large{32 = x \times 2x}[/tex]
Since x multiplies by another x. It becomes x squared.
[tex] \large{32 = 2{x}^{2} }[/tex]
Next, we divide 2 by both sides since we want to solve for x.
[tex] \large{ \frac{32}{2} = {x}^{2} }[/tex]
Simplify 32/2 in simplest form.
[tex] \large{16 = {x}^{2} }[/tex]
Square both sides so we can get rid the x squared, leaving only x.
[tex] \large{ \sqrt{16} = \sqrt{ {x}^{2} } }[/tex]
Normally, when solving quadratic equation, you must write plus or minus. However, for this circumstance - we are solving a variable for length and width which cannot be negative. Therefore
[tex] \large{4 = x}[/tex]
After we solve for x. Substitute x = 4 in width = x and length = 2x.
[tex] \large{ \tt{width = x = 4}} \\ \large{ \tt{length = 2x = 2(4) = 8}}[/tex]
When we multiply these two numbers, we get 32 cm^2.
Next, we find the perimeter. The formula of perimeter for rectangle is:
[tex] \large \boxed{ \tt{P = (width + length) \times 2}}[/tex]
We know width and length which are 4 and 8 in order. Substitute in the formula.
[tex] \large{P = (4 + 8) \times 2} \\ \large{P = 12 \times 2} \\ \large \boxed{P = 24}[/tex]
Hence, the perimeter is 24.
Answer
The perimeter for the rectangle is 24.after you list the factors, you have to read the question back .. the question the length of the rectangle is twice the width .. so 4 × 8 is the correct answer .. and you do as usual to calculate the perimeter ..

A) x = -2
B) y =2
C) y= -2
Answer:
Step-by-step explanation:
This is a positive parabola so it opens upwards. The equation for the directrix of this parabola is y = k - p. k is the second number in the vertex of the parabola which is (0, 0), but we need to solve for p.
The form that the parabola is currently in is
[tex]y=a(x-h)^2+k[/tex] so that means that [tex]a=\frac{1}{8}[/tex]. We can use that to solve for p in the formula
[tex]p=\frac{1}{4a}[/tex] so
[tex]p=\frac{1}{4(\frac{1}{8}) }[/tex] which simplifies to
[tex]p=\frac{1}{\frac{1}{2} }[/tex] which gives us that
p = 2. Now to find the directrix:
y = k - p becomes
y = 0 - 2 so
y = -2, choice A.

Use △DEF, shown below, to answer the question that follows: What is the value of x rounded to the nearest hundredth? Type the numeric answer only in the box below
Answer:
x=63.25
Step-by-step explanation:
Hi there!
We're given ΔDEF with m<E=90°, m<D=49°, DE=55, and EF=x
we need to find the value of x
Let's use trigonometry to do it
Since we are given the measures of the 2 legs (the sides that make up the 90° angle), let's use tangent, specifically tan(49), since we are given the measure of that angle
Recall that tangent is [tex]\frac{opposite}{adjacent}[/tex]
in reference to m<D (the angle that is 49°), the opposite side is EF (x) and the adjacent side is DE (55)
so tan(49)=[tex]\frac{x}{55}[/tex]
plug tan(49) into your calculator; remember to have the calculator on degree mode
tan(49)≈1.15 (rounded to the nearest hundredth)
so that means:
1.15=[tex]\frac{x}{55}[/tex]
multiply both sides by 55 to clear the fraction
63.25=x
Hope this helps!

James fenced in his backyard. The perimeter of his fence is 20 feet, and the width of his yard is 2 feet wide. Use the perimeter formula to find the length of his rectangular yard
in inches: P2L+2W.
Answer:
Length = 8 feet
Step-by-step explanation:
Perimeter = 2 x ( length + width )
20 = 2 x (length + 2)
10 = Length + 2
10 - 2 = Length
Therefore, Length = 8 feet
Given any triangle ABC labeled as shown the law of sines states that:
A researcher asks participants to rate the tastes of three different cola drinks. The size, shape, and color of the drink cups are the same for each drink. In this study, the independent variable is __________, the dependent variable is __________, and an extraneous variable is __________. Group of answer choices drink cups, taste rating of cola drink, type of cola drink type of cola drink, drink cups, taste rating of cola drink type of cola drink, taste rating of the cola drink, drink cups drink cups, type of cola drink, taste rating of cola drink
Answer:
Independent variable - type of cola drink
dependent variable - taste rating of cola drink
extraneous variable - type of cola drink
Step-by-step explanation:
The independent variable is the variable that the person carrying out an experiment changes or manipulates. the independent variable usually have a direct effect on the dependent variable
The dependent variable is the variable that is being measured in an experiment. It is usually affected by the independent variable.
The extraneous variable is the variable that is not been researched in the experiment but it has the potential to influence the results of the experiment.
The type of cola drink given to participants can be manipulated to derive different ratings. the ratings that participants would give the cola drink is determined by the type of cola drink served. Here, the type of drink served is the independent variable while the ratings given is the dependent variable.
the extraneous variable is the type of drink cups used. this is not relevant to the experiment but can affect the results of the experiments. for example, imagine a red cup is used for the experiment and a participant hates red cups. it is more likely that the participant would give a low rating for the cola drink even if the drink tastes good

The Marked price of a jacket at a dealer's shop is 2400. The dealer allows a discount of 15% to the retailer. As the company's policies the marked price of the retailer should be the same as the dealer's marked price. What SP should the retailer fix for the jacket? What would its final price be if 10% VAT is imposed? What would be the actual gain of retailer?
Ans
2280,2502,240
Answer:
2400
2640
360
Step-by-step explanation:
I am not sure the description is totally clear.
my assumptions are (based on my interpretations of the text) :
the retailer buys from the dealer with 15% discount.
but the retailer has to sell the jacket for the same price as the dealer.
so, both mark the sale price as 2400.
if the customer buys from the retailer, the retailer makes 15% profit (the discount he got from the dealer).
15% = 2400 × 15/100 = 24 × 15 = 360
the retailer makes this profit no matter what other fees or taxes are added.
if the customer buys from the dealer, the dealer makes these 15% and some more (we don't know how much) profit.
now, the final price is to include also 10% VAT
100% = 2400
1% = 2400 / 100 = 24
10% = 24 × 10 = 240
so,
final price = SP + VAT = 2400 + 240 = 2640
