Answer: The perimeter of the largest triangle = 117 units.

Step-by-step explanation:

Sides of smaller triangle = 10,20 and 15 units

Longest side = 20 units

Longest side of larger triangle = 52 units

Sides of two similar triangles are proportional.

Let k be proportionality constant.

[tex]k=\dfrac{\text{Length in larger triangle}}{\text{Length in smaller triangle}}[/tex]

[tex]k=\dfrac{52}{20}\\\\\Rightarrow\ k=\dfrac{13}{5}[/tex]

Length of other two sides,

[tex]10\times\dfrac{13}{5}, 15\times\dfrac{13}{5}\ i.e.\ 26\text{ units}, 39\text{ units.}[/tex]

So sides of larger triangle = 52 units, 26 units , 39 units

Perimeter of largest triangle = 52 +26+39 = 117 units

Hence, the perimeter of the largest triangle = 117 units.

She is right, however her explanation is wrong.

In order to find the unit price, you need to divide the amount by the cost.

You will then see that 12 divided by 2.39 < 18 divided by 3.39.

The smaller unit price is obviously the better buy.

Answer:

i think C im not really sure but i hope im correct maybe >.<

Answer:

2/3

Step-by-step explanation:

Pretty simple to find. Divide both the top and the bottom by 4, and see that it makes 2/3. Easy way to figure out any of these is just to simpliy them. Like 10/12 would equal 5/6

Incomplete question. I provided an explanation about the term, "business model."

Explanation:

Usually, when mention is made of the term business model it simply refers to the decided way a business plans to make profits.

In other words, it includes information about services or products to be offered by the business in other to keep the business alive, but not just been alive but to continue growing profit-wise.

Hence, we can say, Henry's business model should contain information about the dog charges which would be profitable to his business.

Answer:

y = - 3x + 11

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = [tex]\frac{1}{3}[/tex] x - 3 ← is in slope- intercept form

with slope m = [tex]\frac{1}{3}[/tex]

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{1}{3} }[/tex] = - 3, then

y = - 3x + c ← is the partial equation

To find c substitute (3, 2) into the partial equation

2 = - 9 + c ⇒ c = 2 + 9 = 11

y = - 3x + 11 ← equation of perpendicular line

Answer:

We conclude that the expression of the price p of a coat reduced by a 5% discount​ will be: 0.95 p      

Step-by-step explanation:

Let 'p' be the original price

Discount = 5% = 0.05

The discount amount can be calculated by multiplying the original price by 5% or 0.05

Discount Amount = 5% × p

                             = 0.05 × p

                             = 0.05 p

Given that the price p of a coat reduced by a 5% discount​.

Thus, the price after 5% discount​ can be calculated by subtracting the discount amount i.e. 0.05 p from the original price p.

Thus,

The expression of the price p after 5% discount​ = p - 0.05 p

                                                                                = 0.95 p

Therefore, we conclude that the expression of the price p of a coat reduced by a 5% discount​ will be: 0.95 p

Answer:

D) y =   -2

The equation of the perpendicular line to the given line is  y = -2

Step-by-step explanation:

Explanation:-

Given point (-3,-2)

In graph the equation of line  x = 8 ( parallel to y- axis )

                              1 x + o y - 8 =0

The equation of the perpendicular line to the given line  

                        b x - a y + k =0

                       o x - 1 y + k =0 ...(i)

The equation (i) is Paases through the point ( -3,-2)

                        0 ( -3) -1(-2) + k =0

                               2 + k =0

                                     k = -2

∴The equation of the perpendicular line to the given line  is

     put k = -2 in equation (i)    

                        o x - 1 y + k =0

                      - y +(-2) =0

                       - y = 2

                         y = -2

Final answer:-

∴The equation of the perpendicular line to the given line is  y =-2

Answer:

10

Step-by-step explanation:

i think its 10 maybe cuz if u see

the perimeter of a rectangular room is 52 feet. right?

then then height is 2 more than the width. what is the width of the room? so am I right copying the question? yes the question is right copied ok!

now see when u subtract 2 from 12 it gives u 10 and length i as 2 more than the width so maybe 10

Answer:

Over time, mathematicians have developed a set of rules called the order of operations to determine which operation to do first. The rules are: Multiply and divide from left to right. Add and subtract from left to right.

Step-by-step explanation:

Order of operations tells you to perform multiplication and division first, working from left to right, before doing addition and subtraction. Continue to perform multiplication and division from left to right. Next, add and subtract from left to right.

Can you insert an image or retype the question, it is hard to read with the information that is incorrectly placed.

Answer:

Slope = 8 Y-intecept = (0, 3)

Step-by-step explanation:

Slope-intercept form: y = mx + b

m = slope

b = y intercept value

y = 8x + 3

m = 8

y = 3
