(e) The area of triangle H is 4/9 times the area of triangle G.

(f) The area of triangle B is 9/16 times the area of triangle H.

(a) Triangle G and Triangle F

Consider triangle F,

The height of the triangle is 8.

The base of the triangle is 6.

The hypotenuse of the triangle is 10.

Area of ΔF = ( 1/2 ) × b × h = ( 1/2 ) × 6 × 8 = 24 square units.

Consider triangle G,

The height of the triangle is 4.

The base of the triangle is 3.

The hypotenuse of the triangle is 5.

Area of ΔG = ( 1/2 ) × b × h = ( 1/2 ) × 3 × 4 = 6 square units.

Therefore,

Area of ΔF = 4 × Area of ΔG

(b) Triangle G and Triangle B

Consider triangle G,

The area of the triangle is:

Area of ΔG = ( 1/2 ) × b × h = ( 1/2 ) × 3 × 4 = 6 square units.

Consider triangle B,

The height of the triangle is 2.

The base of the triangle is 3/2.

The hypotenuse of the triangle is 5/2.

Area of ΔB = ( 1/2 ) × b × h = ( 1/2 ) × 3/2 × 2 = 3/2 square units.

Now, 4 × 3/2 = 6

Therefore,

Area of ΔG = 4 × Area of ΔB

Area of ΔB = 1/4 × Area of ΔG

(c) Triangle B and Triangle F

Consider triangle B,

Area of ΔB = ( 1/2 ) × b × h = ( 1/2 ) × 3/2 × 2 = 3/2 square units.

Consider triangle F,

Area of ΔF = ( 1/2 ) × b × h = ( 1/2 ) × 6 × 8 = 24 square units.

Now, 16 × 3/2 = 24

Therefore,

Area of ΔF = 16 × Area of ΔB

(d) Triangle F and Triangle H

Consider triangle F,

Area of ΔF = ( 1/2 ) × b × h = ( 1/2 ) × 6 × 8 = 24 square units.

Consider triangle H,

The height of the triangle is 8/3.

The base of the triangle is 2.

The hypotenuse of the triangle is 10/3.

Area of ΔH = ( 1/2 ) × b × h = ( 1/2 ) × 2 × 8/3 = 8/3 square units.

Now, 9 × 8/3 = 24

Therefore,

Area of ΔF = 9 × Area of ΔH

Area of ΔH = 1/9 ×  Area of ΔF

(e) Triangle G and Triangle H

Consider triangle G,

Area of ΔG = ( 1/2 ) × b × h = ( 1/2 ) × 3 × 4 = 6 square units

Consider triangle H,

Area of ΔH = ( 1/2 ) × b × h = ( 1/2 ) × 2 × 8/3 = 8/3 square units.

Now,

9/4 × 8/3 = 6

Therefore,

Area of ΔG = 9/4 × Area of ΔH

Area of ΔH = 4/9 × Area of ΔG

(f) Triangle H and Triangle B

Consider triangle H,

Area of ΔH = ( 1/2 ) × b × h = ( 1/2 ) × 2 × 8/3 = 8/3 square units

Consider triangle B,

Area of ΔB = ( 1/2 ) × b × h = ( 1/2 ) × 3/2 × 2 = 3/2 square units

Now,

16/9 × 3/2 = 8/3

Therefore,

Area of ΔH = 16/9 × Area of ΔB

Area of ΔB = 9/16 × Area of ΔH

If Natasha is taking out a three week payday loan for $400. He will be charged with $70 interest for a 3 week loan. the APR (annual percentage rate) is $304.2

Using this formula to determine the annual percentage rate
APR = [(( interest/principal)/number  of days )×365]×100

Principal = $400

Interest = $70

Number of days = 3 weeks = 21 days

Let plug in the formula

APR  = [(( 70 / 400)/ 21) ×365 ] ×100

APR  = 0.008333 x 365 × 100

APR =  304.166

Shortest side of a triangle is  x - 2 = 7 - 2 = 5cm.

Given,

Triangle is a Right - angled triangle

Base of triangle is = x + 4

Height of triangle is = x -2

The area of the triangle is 27.5 cm²

To find the length of the shortest side of the triangle.

Now, According to the question:

We know that

Area of triangle is = 1/2 x base x height

Put the values of base and height in above formula

27.5  = 1/2 × (x + 4) × (x - 2)

27.5 × 2 = x (x - 2) + 4(x -2 )

55 = [tex]x^{2} + 4x - 2x - 8[/tex]

[tex]x^{2}[/tex] + 2x - 63 = 0

[tex]x^{2}[/tex] + 9x - 7x - 63 =0

Answer:

x=7

Step-by-step explanation:

5(2x-5) = 10x-25

1) add 25 to both sides

10x+25=10x      6x+3+25=6x+28

10x=6x+28

2) subtract 6x from both sides

10x-6x=4x      6x+28-6x=28

4x=28

3) divide by 4 from both sides

4x/4=x      28/4=7

The value of y in the expression -5(2x - 5) = 6x + 3 is 22/16

According to the given question

We have an equation in one variable

⇒  -5(2x - 5) = 6x + 3

For finding the value of x solve the above equation by adding and subtracting the like terms.

So, -5(2x - 5) = 6x + 3

⇒ -5 x 2x + 5 x 5 = 6x + 3

⇒ -10x + 25 = 6x + 3

⇒  25 - 3 = 6x + 10x

⇒  22 = 16x

⇒ x = 22/16

Hence, the value of y in the expression -5(2x - 5) = 6x + 3 is 22/16

Using proportions, it is found that:

a) Jana runs faster, due to the higher velocity.

b) Jana's speed is of 47,520 feet per hour.

c) Jana's speed is of 792 feet per minute.

A proportion is a fraction of a total amount, and equations can be built to find the desired measures in the problem using relations with operations such as multiplication and division.

One example of the application of proportions in this problem is for the relation between velocity, distance and time, as velocity is distance divided by time, that is:

v = d/t.

Hence the velocities in this problem are given as follows:

Due to the higher velocity, Jana runs faster.

Another application of proportions is for conversion of units. Each mile has 5280 feet, hence Jana's speed in feet per hour is given by:

9 x 5280 = 47,520 feet per hour.

Each hour has 60 minutes, hence Jana's speed in feet per minute is given by:

47520/60 = 792 feet per minute.

BODMAS is an acronym to remember the order of mathematical operations – the correct order in which to solve maths problems. Bodmas stands for

B-Brackets,

O-Orders (powers/indices or roots),

D-Division,

M-Multiplication,

A-Addition,

S-Subtraction.

Solve the given expression,

(-2.678) + 4.5 + (-0.68)

Follow the Bodmas rule, to solve the given expression.

First, open the brackets,

-2.678 + 4.5 - 0.68

Now, put together -ve terms

-2.678 - 0.68 + 4.5

Add the -ve terms, we get

-3.358 + 4.5

Now subtract this, we get

The slope of the table is 3.

In this question, we have been given a table.

We need to find the slope of the table.

For aby two points (x1, y1) and (x2, y2), we use the formula of slope,

m = (y2 - y1) / (x2 - x1)

m1 = (15 - 30) / (-5 - 0)

m1 = (-15) / (-5)

m1 = 3

For a pair of points (-5, 15) and (10, 60)

m2 = (60 - 15) / (10 + 5)

m2 = 45 / 15

m2 = 3

For a pair of points (10, 60) and (5, 45)

m3 = (45 - 60) / (5 - 10)

m3 = -15 / -5

m3 = 3

Therefore, the slope of the table is 3.

The required equation is x+4y-9 = 0.

What is an equation?

Algebra is concerned with two types of equations: polynomial equations and the particular case of linear equations. Polynomial equations have the form P(x) = 0, where P is a polynomial, while linear equations have the form ax + b = 0, where a and b are parameters, when there is only one variable. To solve equations from either family, algorithmic or geometric approaches derived from linear algebra or mathematical analysis are used. Algebra also investigates Diophantine equations with integer coefficients and solutions. The approaches employed are unique and derive from number theory. In general, these equations are complex; one frequently searches just for the existence or lack of a solution, and, if they exist, the number of solutions.

The equation is formed below

(y-2) = {(1-2)/(3+1)} (x+1)

or, y-2 = - 1/4 (x+1)

or, 4(y-2) = -1(x+1)

or, 4y - 8 = 1 - x

or, x+4y-9 = 0

Given:

The given angles are:

∠WYX = (4x - 2)°

∠WXY = 62°

The length of side WX = 8

The length of side WY = 8

So, WX = WY = 8, hence it is an isosceles triangle.

By Isosceles Triangle Theorem,

∠WYX = ∠WXY

(4x - 2)°= 62°
