I dont know the answer

Step-by-step explanation:

but try to use proportional relationships

good luck : )

Answer:(number)=-5

Step-by-step explanation:

You can use simple logic in order to solve this equation.

An equation that has infinitely many solutions will have the same exact numbers on both sides

Example: 3x = 3x, it has infinite solutions because no matter what number you put, the equation will always be true

The solution for this equation is -5 because when -5x-19=-5x-19, no matter what number you put as a solution, it will be true.

Answer:

Lets start:

Picture 1:-

1. Length of EH= 12cm

2. Angle G= 55 degrees

Picture 2:-

1. Scale factor= 1/4 (I'm not sure about this but this is what I think it is ;-;)

2. Value of y= 28 cm

Picture 3:- [Picture 3 is cropped so I'm guessing its the last one so imma answer those questions :D]

1. Scale factor= 5 (Again I'm not sure but its my best guess)

2. Value of z= 5

Picture 4:-

1. Scale factor= 4 (I'm pretty sure you know that my scale factor answers are guesses so yea ;-;)

2. Value of b= 12

It'll help you understand how we solve these questions

Well anyways i hope this clears your concepts :D

Answer:

Step-by-step explanation:

EH is 12cm as the shape has been enlarged by scale factor two (all sides have been multiplied by 2).

Angle G remains the same at 55 degrees.

PART A

Scale factor for the triangle = 1/4

Value of y = 28cm

3) z = 5, scale factor = 5

SIMILAR RECTANGLES:

Scale factor = 4

Side b = 12cm

Hope these answers work out for you

Answer:

150 = x

Step-by-step explanation:

We can use a ratio to solve

100 batches          x batches

------------------- = ---------------------

8 hours                12 hours

Using cross products

100 * 12 = 8x

1200 = 8x

Divide by 8

1200/8 = 8x/8

150 = x

Answer:

150

Step-by-step explanation:

Find how many batches in one hour

100/8 = 12.5

Multiply 12 hours with 12.5 batches

12 x 12.5 = 150

So, in 12 hours 150 batches are made.

Answer:To write the number 0.0000149 in scientific notation, we need to express it as a number between 1 and 10 multiplied by a power of 10.

First, we move the decimal point to the right until there is only one non-zero digit to the left of the decimal point, which gives us:

1.49 × 10^-5

Since we moved the decimal point 5 places to the right, the exponent of 10 is negative 5.

Therefore, the scientific notation of 0.0000149 is 1.49 × 10^-5.

Step-by-step explanation:

Answer:

1.49×10^-5

Step-by-step explanation:

0.0000149=1.49×10^-5

it's to the power of -5 because it's a decimal number not a whole number

Answer:

y = 21

x = 8

Step-by-step explanation:

AB = 180

27 + 3y = 90°

-27           -27

-----------------------

3y = 63

÷3     ÷3

--------------

y = 21

x + 27 + 3y + 8x + 18 = 180

9x + 45 + 3(21) = 180

9x + 45 + 63 = 180

9x + 108 = 180

      -108   -108

-----------------------

9x = 72

÷9    ÷9

----------------

x = 8

I hope this helps!

Explanation:

The data from the stem-and-leaf plot is:

10,

24,25,26,

30,30,32,33,

40,45,46

Add up those values

10+24+25+26+30+30+32+33+40+45+46 = 341

Then divide over n = 11 which is the sample size.

341/11 = 31 is the arithmetic mean.

Answer:

341/11 = 31 is the arithmetic mean.

Answer:

2.25 cm³

Step-by-step explanation:

The volume of a pyramid can be found using the formula:

\( \boxed{\text{volume of pyramid= ⅓×base ×height}}\)

Base area

= area of square

= side ×side

= 1.5²

= 2.25 cm²

Volume of paperweight

= ⅓(2.25)(3)

= 2.25 cm³

Step-by-step explanation:

(2/3)(-4)(9) = -24
