Answer:

Step-by-step explanation:

First you must know that the sum of angle in a triangle is 180degrees

In triangle JKL, <J+<K+<L = 180 ..... 1

If m<J is 7 less than m<L , then;

m<J = m<L -7 ..... 2

If m<K is 21 less than twice m<L then;

m<K = 2m<L - 21 ...... 3

Substitute 2 and 3 into 1;

from 1; m<J+m<K+m<L = 180

m<L - 7 + 2m<L - 21 + m<L = 180

4m<L - 28 = 180

4m<L = 180+28

4m<L = 208

m<L = 208/4

m<L = 52 degrees

Get m<J;

m<J = m<L -7

m<J = 52-7

m<J = 45 degrees

Get m<K;

m<K = 2m<L - 21

m<K = 2(52) - 21

m<K = 104 - 21

m<K = 83degrees

Answer:

(-9,-2)

Step-by-step explanation:

The translated coordinates are (-1,4).

The process of changing the location of the image on the coordinate system will be known as the translation. The translation is done on the coordinate plane a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis.

Given that A sergeant received an order to relocate the squad from its current location T (3, -2) on the coordinate plane to a new location S. The movement of the squad is described by the translation (x, y)⟶(x-4, y+6).

The translated points will be calculated as below:-

( 3, -2 ) ⇒ [ ( 3 - 4 ) , ( -2 + 6 ) ]

( 3, -2 ) ⇒ [ ( -1 ) , ( 4 ) ]

Therefore, the translated coordinates are (-1,4).

Step-by-step explanation:

Answer:

The dimensions have to be reduced by 2 inches

Step-by-step explanation:

Given that the dimensions are: 6 by 8 inches which means that the area is 48 square inches.

Let x be the amount to make a new photo which is half of the area that means

The new dimensions will be: (8-x) by (6-x) and as the area is half

The area of new photo will be: 48/2 = 24

Putting it mathematically

[tex](8-x)(6-x) = 24\\8(6-x)-x(6-x)=24\\48-8x-6x+x^2=24\\48-14x+x^2=24\\x^2-14x+48-24=0\\x^2-14x+24=0\\x^2-12x-2x+24=0\\x(x-12)-2(x-12)=0\\(x-2)(x-12)=0\\x-2=0 => x=2\\x-12=0 =>x=12[/tex]

Subtracting 12 from both dimensions will make them negative so 12 cannot be the solution.

Hence,

The dimensions have to be reduced by 2 inches

We want to see by how much we must reduce the dimensions of the photograph in order to reduce its area to half. We will find that we must reduce each measure by 2 inches.

The original measures of the photograph are:

Then the area is:

A = (6 in)*(8 in)  = 48 in^2

Now we want to define a new length and a new width:

such that:

A' = L'*W' = 24 in^2

      (6 in - n)*(8in - n)  = 24 in^2

      48in^2 - n*14 in + n^2 = 24 in^2

    n^2 - n*14 in + 24in^2 = 0

This is a quadratic equation, we can solve this for n by using Bhaskara's formula, we will get:

[tex]n = \frac{14in \pm \sqrt{(-14)^2 - 4*1*24in^2} }{2*1} \\\\n = 7in \pm 5 in[/tex]

The only solution that makes sense is:

n = 7in -  5in = 2in

This means that we need to reduce each measure by 2 inches.

Answer:

If the rational number is a fraction (of course) divide it. For example, 1/2 can be divided as 1 divided by 2 which is 0.5.

If the number is an integer, you can simply just add .0 (point zero). For example, if the rational number is 12, the decimal version would be 12.0.

If the number is a fraction, you can divide the numerator by the denominator. For example, if the rational number is 1/10 (one tenth), just can divide one by zero to get 0.1 (zero point one).

Answer:

0.63km/h

Step-by-step explanation:

Step one:

given data

total distance= 5km

velocity of walk= 4km/h

distance covered while walking= 1km

time taken to walk

t1= 4/1

t1= 4hours

Step two:

velocity of bus= 16km/h

distance covered while walking= 5-1= 4km

time taken to walk

t2= 16/4

t2= 4hours

total time = 4+4=8hours

Average speed= total distance/total time taken

average speed= 5/8

average speed=0.63km/h

Answer:

The mean saving was $744.54 per hour to fill out Schedule A tax form.

Step-by-step explanation:

Given that:

Time taken by Rodriguez family = 5.5 hours

Amount saved in taxes = $4095

5.5 hours = $4095

The mean savings per hour can be calculated by dividing the total hours taken by the amount saved in taxes.

1 hour = [tex]\frac{4095}{5.5}\\[/tex]

1 hour = $744.54

Savings per hour = $744.54

Hence,

The mean saving was $744.54 per hour to fill out Schedule A tax form.

Answer:

-0.39, -0.38, -0.37, -0.36, -0.35, -0.34, -0.33, -0.32, -0.31, -0.3

Step-by-step explanation:

Rational numbers are basically any number that are not numbers with non-recurring decimals or non-terminating decimals.

-[tex]\frac{2}{5}[/tex] = -0.4

[tex]\frac{1}{2}[/tex] = 0.5

Thus, any number from -0.4 to 0.5 with decimals (if any), that will terminate and not stretch forever is rational. [tex]\frac{1}{3}[/tex] is not rational. Decimals that repeat are also rational. pi is not rational.

Answer:

16 and 13

Step-by-step explanation:

Let the second no is x

First no = x+3

Twice the first is nine less than three times the second.

We can write in the form of equation as follows :

2(x+2) = 3x-9

Solving brackets first

2x+4=3x-9

Taking like terms together

9+4=3x-2x

13=x

First no = x+3 = 13 + 3 = 16

So, first and second numbers are 16 and 13 respectively.
