Step-by-step explanation:

For percentage profit questions, use this formula:

Percentage 'change' = 'change' / original x 100

(where 'change' is the difference between the 2 values)

Now subsitute the values:

Percentage Change = 10770 / 179500 × 100

Answer:

(41/5, 6/5)

Step-by-step explanation:

2x+-2y=14

x+4y=13

You can multiply the first equation by 2 so you can eliminate the y:

2(2x+-2y=14)

4x+-4y=28

Then you can set up both equations to be added together:

 4x+-4y=28

+ x+4y=13    

5x=41

x=41/5

Then you can substitute 41/5 for x in the original equation:

x+4y=13

41/5+4y=13

5(41/5+4y)=5(13)

41+20y=65

20y=24

y=24/20

y=6/5

Check:

2x+-2y=14

2(41/5)+-2(6/5)=14

82/5+-12/5=14

70/5=14

14=14

temperature is   -2°C

by 11 AM        is  -2-3=-5°C

at 4 PM          is       0°C

the integer is 5

Step-by-step explanation:

Which means that the first number is 149, the second number is 149 + 1 and the third number is 149 + 2. Therefore, three consecutive integers that add up to 450 are 149, 150, and 151. We know our answer is correct because 149 + 150 + 151 equals 450 as displayed above.

PLEASE MARK ME AS BRAINLIEST ANSWER

HOPE IT HELPS YOU

The three consecutive integers that add up to 450 are 149, 150, and 151.

The consecutive numbers are those numbers that follow each other continuously in the order from smallest to largest numbers.

Given that the sum of three consecutive even numbers is 450

We need to find the 3rd number of the integers.

Now assume the 3 consecutive integers are x, (x+1) and (x+2)

Therefore, x+(x+1)+(x+2)= 450

Combine the like terms;

3x+3=  450

X=149

Thus the second number is 149 + 1 and the third number is 149 + 2.

Hence, the 3rd number of the integers would be 151.

Answer:

f(5)=14

Step-by-step explanation:

f(5)=2(5)+4

f(5)=10+4

f(5)=14

Answer:

14

Step-by-step explanation:

Ignore the f(x) for now.

x is 5, so we plug it in to get 2*5+4. Using PEMDAS, you multiply 2 and 5 to get 10 and add 4 to get 14.

Answer:

Step-by-step explanation:

the question is asking for the length of the side labeled x

use Pythagoras'  theorem to find that side

where c = x   because c represents the hypotenuse in the theorem and x is on the hypotenuse in this problem

c = [tex]\sqrt{a^{2} + b^{2} }[/tex]

sooo  plug in a = 14 and b = 10

c = [tex]\sqrt{14^{2} + 10^{2} }[/tex]

c = [tex]\sqrt{196+100}[/tex]

c = [tex]\sqrt{296}[/tex]

c= 17.20465.....  ( that's the approx. length of side x in the problem )

since this is a right triangle we could use trigonometry to find the two angles use SOH CAH TOA  to remember how those functions fit on the triangle.

Sin(Ф)=Opp/Hyp  Cos(Ф)=Adj/Hyp  Tan(Ф)=Opp/Adj

since we know the Hyp (hypotenuse) and the side adjacent will be the side with the 10 soooo...

Cos(Ф)=10/17.20465

Ф = arcCos(10/17.20465)

Ф = 54.4623°  is the angle on the side with 10

the side with 14 then has an angle of 35.5376°

Answer:

5/8

Step-by-step explanation:

1/4=2/8 (This is to find a common denominator).

2/8+3/8=5/8 (When adding fractions, ONLY add the numerator, not the          denominator).

Answer:

5/8

Step-by-step explanation:

1/4 = 2/8 ,

so 2/8 + 3/8 is 5/8

Answer:

x(y² - 4) = 1.512

Step-by-step explanation:

We need to evaluate the following expression for x = 0.2 and y = 3.4 :

x(y² - 4)

Put the values of x and y.

x(y² - 4) = (0.2)((3.4)² - 4)

= (0.2)((3.4)² - 4)

= 0.2×7.56

= 1.512

So, the value of the above expression is 1.512

Answer:

A={5,1,-7}

Step-by-step explanation:

domain = x

choose domain {-2,0,4} to 2x+y=1

range = y

range is

2(-2)+y =1 ,y =5

2(0)+y=1, y= 1

2(4)+ y=1, y=-7

range = {5,1,-7}

Answer: 9(2x-1)

Step-by-step explanation:

Answer:

See explanations below

Step-by-step explanation:

Given the quadrilateral ABCD

A(3,0),B(-4,4),C(-7,0) and D(-3,-5)

The sides of the quadrilateral are AB, BC, CD and AD

The midpoint coordinate of the line is expressed as;

X = x1+x2/2

Y = y1+y2/2

Given A(3,0),B(-4,4)

Midpoint of AB = (3-4/2, 0+4/2)

midpoint of AB = (-0.5, 2)

Given B(-4, 4),C(-7, 0)

Midpoint of BC = (-4-7/2, 4+0/2)

midpoint of BC = (-11/2, 4/2)

Midpoint of BC = (-5.5, 2)

Given C(-7, 0) D(-3,-5)

Midpoint of CD = (-7-3/2, 0-5/2)

midpoint of CD = (-10/2, -5/2)

Midpoint of CD = (-5, -2.5)

Given A(3,0),D(-3, -5)

Midpoint of AD = (3-3/2, 0-5/2)

midpoint of AD = (0/2, -5/2)

Midpoint of AD = (0, -2.5)

Answer:

58[tex]\sqrt{65}[/tex]

Step-by-step explanation:

you can find the height of this trapezoid by using the pythagorean theorem where the hypotenuse is 18 and one leg is 8 (33-25)

let x = height

[tex]8^{2}[/tex] + [tex]x^{2}[/tex] = [tex]18^{2}[/tex]

[tex]x^{2}[/tex] = 324 - 64

[tex]x^{2}[/tex] = 260     therefore, x = [tex]\sqrt{260}[/tex]

[tex]\sqrt{260}[/tex] = [tex]\sqrt{4}[/tex]· [tex]\sqrt{65}[/tex]  or  2[tex]\sqrt{65}[/tex]

A = [tex]\frac{1}{2}[/tex]h x (sum of the bases)        

bases are 25 and 33

A = (2[tex]\sqrt{65}[/tex]) ÷ 2)58

Answer:

I think it should be Neither A nor B

Answer:

one-solution

Step-by-step explanation:

(x + 2y = 6)2

2x - 3y = 26

2x + 4y = 12

2x - 3y = 26

7y = -14

y = -2

x + 2(-2) = 6

x + -4 = 6

x = 10

Answer:

Step-by-step explanation:

It is two lines, if they intersect there is one solution, if parallel- no solution, if  same lines- infinitely many solutions

Lets put them in slope-intercept form and compare:

As we see the lines have different slopes, so they intersect which means one solution only.
