Which equation doesn't belong? Explain your reasoning. 1. 1/4x = 27 2. 3x = 36 3. 3/4x = 9 4. 4x = 48

Answers

Answer:

1/4x = 27

Step-by-step explanation:

Given the equations :

1.)

1/4x = 27 ;

x/4 = 27

x = 27 * 4

x = 108

2.)

3x = 36

Divide both sides by 3

x = 36/3

x = 12

3.)

3/4x = 9

3x / 4 = 9

3x = 9*4

3x = 36

x =. 36/3

x = 12

4. 4x = 48

x = 48/4

x = 12

All other equations equal to 12 except (1)

Chip’s favourite snack food is Dingles potato chips. He enjoys layering 3 chips together to make a stack of interesting flavours. If he only has Regular flavoured Dingles, there is only one way to stack the three chips. That is Regular, Regular and Regular which can be written as rrr. The order in which the chips are layered does not matter. For example, if we have Regular and BBQ Dingles then the stack BBQ, BBQ and Regular (bbr) is the same as BBQ, Regular and BBQ (brb).

a) If he has Regular and BBQ flavoured Dingles, list all the different stacks of 3 chips he can make.

b) If he has three flavours of chips, Regular, BBQ, and Vinegar, list all the different stacks of 3 chips he can make.

c) If he adds a fourth flavour, Ketchup, list all the different stacks of 3 chips he can make.

Answer:

-4 < n ≤ 5

Step-by-step explanation:

Since the left inequality is an open circle and going to the right, the sign will be >

Since the right inequality sign is a closed circle and is going left, the sign would be ≤

The open circle ends at -4 so, n > -4

The closed circle ends at 5 so, n ≤ 5

You combine them and it looks like this:

-4 < n ≤ 5

Step-by-step explanation:

Given

See attachment for triangle

Required

Find x

To find y, we make use of the relationship between sides lengths 11 & x and angle 37

The relationship is:

[tex]cos(37) = \frac{11}{x}[/tex]

i.e.

[tex]cos(\theta) = \frac{Adjacent}{Hypotenuse}[/tex]

Make x the subject

[tex]x = \frac{11}{cos(37)}[/tex]

[tex]x = \frac{11}{0.7986}[/tex]

[tex]x = 13.7741[/tex]

[tex]x = 13.8[/tex] -- approximated

Rewrite the following expression with rational exponents. 3 sq root -27x^2 y^7
Show your work

Answers

Answer:

Step-by-step explanation:

The square root is possible only if y≤0

if y>0 the expression lose meaning, in fact (-)(+)(+) = (-) and a square root of a negative number doesn’t exist. x^2 is a square so it is ever positive if x is not 0

if y≤0 can be rewritten as:

3(-27x^2y^7)^1/2

or if we want simplify the expression:

[tex]3 \sqrt{3^2 * (-3) * x^2 * y^6 * y} = 3^2|x||y|^3 (-3y)[/tex] ^1/2

we have to put the symbol of absolute value between x and y because a x^2 and y^6 are numbers that are ever positive, while x and y^3 can be also negative. Thanks to the simbol of absolute value we can “force” them to be positive

OMG PLZ HELP ME! it is due tomorrow.....!

Answers

Step-by-step explanation:

Dilations do not change your angles, so although the length does change, your angles will not. So for your answer, the angles will be the exact same.

For the length, all you have to do is multiply each side by 5/2.

8: Multiplied by 5/2 is 20

9: Multiplied by 5/2 is 22.5

7: Multiplied by 5/2 is 17.5

The lengths are getting larger because they're being dilated by a number greater than 1.

I hope this helps :)

Answer:

Answers bellow hope I helped

Step-by-step explanation:

A)Each angle is the SAME becouse we are just making the triangle larger but the angles stay the same so:

Z' = 50°

X' = 70°

Y' = 60°

B)You have to multiply each of the sides by your scale factor so:

Side X'Y' = 7 x 5/2= 17.5

Side X'Z' = 8 x 5/2 = 20

Side Z'Y' = 9 x 5/2 = 22.5

Answer:

352 sq. inches

Step-by-step explanation:

32 x 22 = 704

704 / 2 = 352

Answer:

352 sq. inches

Step-by-step explanation:

The area of a triangle is found by the formula 1/2bh

aka 1/2 of base times height

the height is 22 and the base is 32 so we multiply 22 by 32

We get 704 but not the end we have to multiply that by 1/2 or divide by 2

Do that and you get 352

b=32      h=22

22*32=704

704/2 or 704*1/2 = 352

2/3 * 360 = 240 inch²

30 * 18= 540 inch²

2/3 * 540 = 360inch²

12 * 15= 180 inch²

2/3 * 180 = 120 inch²

18 * 15= 270 inch²
