the dimensions of a rectangle are increased by a scale factor of 2. if the original rectangle had an area of 16 square feet whay is the area of the large rectangle

Answer:

m = [tex]\frac{16}{3}[/tex] , z = [tex]\frac{24}{5}[/tex]

Step-by-step explanation:

Δ PQT and Δ PRS are similar ( by AA postulate ), so the ratios of corresponding sides are equal, that is

[tex]\frac{PQ}{PR}[/tex] = [tex]\frac{PT}{PS}[/tex] , substitute values

[tex]\frac{m-2}{m}[/tex] = [tex]\frac{5}{8}[/tex] ( cross- multiply )

8(m - 2) = 5m ← distribute parenthesis on left side

8m - 16 = 5m ( subtract 5m from both sides )

3m - 16 = 0 ( add 16 to both sides )

3m = 16 ( divide both sides by 3 )

m = [tex]\frac{16}{3}[/tex]

and

[tex]\frac{QT}{RS}[/tex] = [tex]\frac{PT}{PS}[/tex] , substitute values

[tex]\frac{3}{z}[/tex] = [tex]\frac{5}{8}[/tex] ( cross- multiply )

5z = 24 ( divide both sides by 5 )

z = [tex]\frac{24}{5}[/tex]

Answer:

Acute and Equilateral

Step-by-step explanation:

The little dashes on the sides indicate congruent sides

Each side has a singular dash meaning that all the sides are congruent. If all the sides are congruent then all of the angles are congruent

The angles in an equilateral triangle are 60

An acute triangle angles are all less than 90

All of the angles in a equilateral triangle are less than 90 therefore this is an equilateral acute triangle

Answer:

acute equilateral

Answer: 20x-6 = 34

Step-by-step explanation:

Given: The length of rectangle is represented by 8x - 3.

The width of the rectangle is represented by 2x.

The perimeter is 34 inches.

Perimeter of rectangle = 2 (length + width)

Perimeter of rectangle = 2 (8x-3+2x)

Perimeter of rectangle = 2 (10x-3)

Perimeter of rectangle = 20x-6

Thus , the required equation that represent the perimeter: 20x-6 = 34

Answer:

Slope: -2

Y-Intercept: (0,1)

Step-by-step explanation:

The slope would be m. In this case our m is -2, so our slope is -2.

For the y-intercept, you just look at the constant. So our constant is 1, so the y-intercept is (0,1)

Answer:

56 and 36 are the numbers.

Step-by-step explanation:

Let the numbers be x and y,

x + y = 92

x - y = 20

On solving,

y = 36

x = 56

Answer:

Step-by-step explanation:

0-2 is 30%

3-4  is 20%

5-6 is 20%

7-9 is 30%

so by his estimations a song bird would come up next at 20% of the time

or in 5 birds  100% percent of the time, but we have to look at his empirical data to see how accurate that is hmmm maybe a good time for a spread sheet or Mat Lab ???  hmm

13/20 is what I counted..   or   out of 100

that's 13*5 or 65%  

I'm not sure what form they want it in.. percent..  fraction hmm   hope that will help  :/

Step-by-step explanation:

tangent < I

= p / b

Answer:

Step-by-step explanation:

Given equation of a straight line is,

y = -4 - 2x

Domain of the line (x) → {-3, -2, -1, 0, 1}

Therefore, range for the given set of domain will be,

Range (y) → {2, 0, -2, -4, -6}

[By substituting the value of x in the given equation we get the value of y]

Set of scatter points are,

(-3, 2), (-2, 0), (-1, -2), (0, -4), (1, -6)

Now we plot these points to get the discrete graph as attached.

Answer:

25.9

Step-by-step explanation:

37/10=3.7

3.7*7= 25.9

The first option is the correct one, that is the valid probability distribution.

For any probability distribution we have two main rules.

So, with the second rule we can see which one of the tables is a valid distribution, we will see that for table A the sum is:

Sum(A)=  1

And for the other two:

Sum(B) = 1.08

Sum(C) = 0.9

So we can see that the only valid probability distribution is the one in the first option.

Answer:

slope is -3

y-intercept is -2

Step-by-step explanation:

put into slope-intercept form which is y = mx + b where 'm' is slope and 'b' is the y-intercept

12x + 4y = -8

4y = -12x - 8

y = -12/4x - 8/4

y = -3x - 2 (simplified)
