drag components to describe a sequence of transformations that will show triangle abc is equal to triangle def

Answers

Answer:

Step-by-step explanation:

From the figure attached,

ΔDEF is the image triangle formed by the sequence of transformations of ΔABC.

Step -1

ΔABC is reflected across line BC to get the inverted form of ΔA'B'C' (As shown in the image attached)

Step -2

Further ΔA'B'C' is translated by 4 units to the right to get the image ΔA"B"C".

Step - 3

Further ΔA"B"C" is translated 1 unit down to get the image ΔDEF.

Solve 10=5m/4
Im Confused, Please Help

Answers

Answer:

m = 8

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to Right

Equality Properties

Step-by-step explanation:

Step 1: Define

10 = 5m/4

Step 2: Solve for m

Multiply 4 on both sides:                    40 = 5mDivide 5 on both sides:                      8 = mRewrite:                                               m = 8

Step 3: Check

Plug in m into the original equation to verify it's a solution.

Substitute in m:                    10 = 5(8)/4Multiply:                                10 = 40/4Divide:                                   10 = 10

Here we see that 10 does indeed equal 10.

∴ m = 8 is the solution to the equation.

A small business has 15 full-time employees. How many people does the small business employ if the full-time workers make up 30% of the employees the company has?

Answers

Answer:

50 employees

Step-by-step explanation:

The total number of employees the business has will have to be made up the full-time employees and part-time employees.

The number of full-time employees = 15

Let the total number of  employees = x

[tex]15 = 30 percent of x[/tex]

[tex]15 = 30/100 \times x\\x=1500/30 = 50[/tex]

The company has a total of 50 employees

Frieda paid $132 for groceries for her family. This was 1 1/8 as much as she paid for the previous time she shopped. How much did Freda pay on her previous shopping trip

Answers

Answer:

$117.33

Step-by-step explanation:

1 1/8 = 1 + 1/8 = 8/8 + 1/8 = 9/8

She paid 9/8 what she paid the last time.

Let the amount she paid last time equal x.

$132 is 9/8 of x.

9/8 x = 132

8/9 * 9/8 x = 132 * 8/9

x = 117.33

She paid $117.33

What is the slope of a line perpendicular to the line whose equation is
10x – 8y = -80. Fully reduce your answer.

Answers

Answer:

-4/5

Step-by-step explanation:

write the given equation in y=mx+b form, where m is the slope

10x-8y=-80

-8y= -10x-80 divide both sides by -8

y=(10/8)x+10

y=(5/4)x+10

m= 5/4 is the slope of the given function

the slope of an equation that is perpendicular is the negative reciprocal of the given one so is

m= -4/5
