The length of the longer leg of a right triangle is 3 cm more than three times the length of the shorter
leg. The length of the hypotenuse is 4 cm more than three times the length of the shorter leg. Find the
side lengths of the triangle.
Length of the shorter leg:________ cm
Length of the longer leg:
cm
Length of the hypotenuse:
_cm

Answers

Answer 1

Answer:

the length of the shorter leg : 7 cm

the length of the longer leg : 24 cm

the length of the Hypotenuse : 25 cm

Step-by-step explanation:

a = 3b + 3

c = 3b + 4

and we know the general Pythagoras :

c² = a² + b²

(3b + 4)² = (3b + 3)² + b²

9b² + 24b + 16 = 9b² + 18b + 9 + b²

24b + 16 = 18b + 9 + b²

6b + 7 = b²

b² - 6b - 7 = 0

the general solution to such a quadratic equating is

x = (-b ± sqrt(b² - 4ac))/(2a)

in our case

x is called b.

a = 1

b = -6

c = -7

b = (6 ± sqrt((-6)² - 4×1×-7))/(2×1) = (6 ± sqrt(36 + 28))/2 =

= (6 ± sqrt(64))/2 = (6 ± 8)/2

b1 = (6+8)/2 = 14/2 = 7 cm

b2 = (6-8)/2 = -2/2 = -1 cm

a negative number did not make sense for a side length, so,

b = 7 cm

is our solution for one leg.

a = 3b + 3 = 3×7 + 3 = 24 cm

c = 3b + 4 = 25 cm

What is an equation?

An equation is an expression that shows the relationship between two or more numbers and variables.

Z score is given by the equation:

z = (raw score - mean) / standard deviation

Given mean of 61 and a standard deviation of 5.

The z score that corresponds to 2 or more standard deviations below the mean is -2. Hence:

-2 = (x - 61) / 5

Juan owns 7 pairs of pants, 3 shirts, 5 ties, and 6 jackets. How many different outfits can he wear to school if he must wear one of each item?

Answers

To solve this problem, just use multiplication.

[tex]7\text{ pairs of pants}*3\text{ shirts}*5\text{ ties}*6\text{ jackets}=\large\boxed{630\text{ outfits}}[/tex]

You can somewhat think of this situation as a sort of tree. You start with 7 large branches representing the pants, then for every one of those you have 3 medium-sized branches to represent the pairs of pants. Each one of those has 5 sticks for the ties, which in turn each have 6 leaves to represent the jackets and therefore a complete outfit. The solution is found by getting the total number of leaves on the tree.

Suzanne is looking at taking out a personal loan. Opportunity Loans is offering her $1600 at 3.45% for 1 year, with interest compounding monthly. General Loans is offering her $1600 at 4.2% for 1 year, with interest compounding quarterly. Assuming she makes no payments until the 1 year is up, how much interest will have accrued on each loan? On which loan will she earn the least amount of interest?

Answers

Step-by-step explanation:

So the general formula for compound interest is [tex]A = P(1+\frac{r}{n})^{nt}[/tex] where r is the interest rate, t is the time in years, and n is the amount of compounds per year. So plugging in the values for both equations you'll get

Opportunity Loans:

 [tex]A = 1600(1+\frac{0.0345}{12})^{(12)(1)}[/tex]

 [tex]A = 1600(1.002875)^{12}[/tex]

 [tex]A \approx 1600(1.035)[/tex]

 [tex]A = \$1,656.08[/tex]

  Now to find the interest accrued on this loan you simply subtract 1600 from the A or final amount

 [tex]Interest=1656.08-1600\\Interest=56.08[/tex]

General Loans:

 [tex]A = 1600(1+\frac{0.042}{4})^{(4)(1)}[/tex]

 [tex]A = 1600(1.0105)^4[/tex]

 [tex]A \approx 1600(1.042)[/tex]

 [tex]A = 1,668.27[/tex]

 To find the interest we do the same thing we did in the previous problem

 [tex]interest = 1668.27-1600\\interest=68.27[/tex]

Opportunity loans has the least amount of interest after a year

A square has a perimeter of 24cm. What is the length of each side?

Answers

Quick process:

⇒ Square has  4 sides

⇒ We have been given that the perimeter is 24 centimeters

⇒ Each side is equal in value and each side added up together must equal 24.

⇒ So to finish this out we need to divide the given perimeter which is 2 4 by the amount of side a square has which is 4.

⇒ So 24/4 = 6

Check the answer:

6 + 6  = 12

12 + 12 = 24 √

Perimeter of a square =24cm

Formula=4s

So 4s=24

s=24/4

Considering the Leibniz notation to represent the derivative of [tex]y[/tex] with respect to [tex]x[/tex], suppose [tex]y \ = \ f\left(x\right)[/tex] is a differentiable function, let [tex]dx[/tex] be the independent variable such that it can be designated with any nonzero real number, and define the dependent variable [tex]dy[/tex] as

                                                  [tex]dy \ = \ f'\left(x\right) \ dx[/tex],

where [tex]dy[/tex] is the function of both [tex]x[/tex] and [tex]dx[/tex]. Hence, the terms [tex]dy[/tex] and [tex]dx[/tex] are known as differentials

Dividing both sides of the equation by [tex]dy[/tex], yield the familiar expression

6) You have a rectangular backyard that is 90 feet wide. It has an area of 10,800 square feet. You are
putting a fence along one length of the yard.

a. Use the formula for the area of a rectangle A = 1 w, where I is the length, and w is the width. Find
the length of your backyard.

b. The fence costs $12.50 per linear foot. What is the total cost of the fence for one length of the yard?

Answers

Answer:

Length = 120 ft

Total cost = 1500$

Step-by-step explanation:

First, to find the length of the backyard we reverse the formula (A = l * w) and divide 10,800 by 90.

10,800 ft^2 / 90 ft = 120 ft.

we can check this by plugging the length of 120 ft into the formula:

120 ft * 90 ft = 10,800 ft^2.

Next, to find the cost of the single length of fence we multiply our length (120 ft) by the cost ($12.50):

120 * 12.50 = $1500

The mean and the median of the set of scores are the same.

What is mean and median?

Introduction to Mean, Median, and Mode: In statistics, we frequently choose a representative value to roughly characterise the entire collection of data. The name "measure of central tendency" denotes that this representative value is one around which the data is centred. The mean, median, and mode are these central tendencies. The most typical way to measure central tendency is with the mean. In actuality, it represents the mean of the specified set of data. Both continuous and discrete data can be used with it. In most cases, the median shows the midpoint of the given set of data when it is arranged in a specific order.

Mean: - Average value

Median: - Middle term (after arranging in either accending or descending order)

Mean = 445/5 = 89

Median = Middle term = 3rd term = 89

Mean and median are equal.
