What is scale factor?A scale factor is the ratio between corresponding measurements of an object and a representation of that object. If the scale factor is a whole number, the copy will be larger. If the scale factor is a fraction, the copy will be smaller.
The scale drawing of parallelogram having dimensions,
length= 8 inches,height= 3 inchesside length= 3 inchesPerimeter of scale drawing of parallelogram be,
= 2 ( length + side length)
= 2( 8 + 4 )
= 2 x 12
= 24 inches
The drawing has a scale of 4: 1 (Here 4 represent for scale diagram and 1 represent for the actual diagram)
As scale factor,= [tex]\frac{Perimeter \;of\; Scale\; logo}{Perimeter \;of \;Actual\; logo}[/tex]
[tex]\frac{4}{1} = \frac{24}{Perimeter\; of \; Actual\; logo}[/tex]
Perimeter of Actual logo =[tex]\frac{24}{4}[/tex]

Which values are the solutions to the polynomial equation?
0 = x2 – 18x + 65
Answer:
If the question is [tex]2x^{2} -18x+65[/tex] then the answer is no real solution. If the question is 2x - 18x + 65 than the answer is -16x+65
Answer:
x = 13, 5
Step-by-step explanation:
x² - 18x + 65 = 0
step 1: multiply (1) and (65) together
step 2: find two negative numbers to add together to equal -18 but multiply together to equal 65.
step 3: since there isn't a number in front of x² you could:
(x - 13) (x - 5)
x - 13 = 0 x - 5 = 0
+13 +13 +5 +5
x = 13 x = 5
or
(x² - 13x) (-5x + 65)
x(x - 13) -5 (x - 13)
(x - 13) (x - 5)
x - 13 = 0 x - 5 = 0
+13 +13 +5 +5
x = 13, 5

Holly opened a savings account at a local bank. She deposited $3,100.00 into the account 9 years ago. If the account earns an
annual simple interest rate of 7.1%, how much interest has she earned?
Answer:
She has earned $1980.90 in interest.
Step-by-step explanation:
Since we know that she deposited $3100 9 years ago, we know we have to find the amount of interest she gets per year times 9. So $3100*0.071 = $220.10 and then $220.1*9 = $1980.90. Therefore, she has earned $1980.90 in interest.
Answer:
The answer is 1980.9
Step-by-step explanation:
Formula is PxRxT
P=Princlple(Amount of money desposited)
R=Rate the rate in deciaml form. Example: 7.1=0.071
T=Time

Answer:
1. y=3x
2. equal to
Step-by-step explanation:
1. The equation of the line is y=3x because the line has a y-intercept of zero and a slope of 3.
2. The y-intercept of the line on the graph is -2. The y-intercept of y=2x-2 is also -2. So, the two y-intercepts are equal to each other.
Write the slope-intercept form of the equation of the line that is perpendicular to and passes through Point X. Show all work for full credit.
Answer:
[tex]y =\dfrac{12}{5}x + 22[/tex]
Step-by-step explanation:
Slope-intercept form of line:
First find the slope of the line AB. ie, m
Slope of the perpendicular line = -1/m
(2 , 3) ⇒ x₁ = 2 & y₁ = 3
(-10, 8) ⇒ x₂ = -10 & y₂ = 8
[tex]\boxed{Slope=\dfrac{y_2-y_1}{x_2-x_1}}[/tex]
[tex]= \dfrac{8-3}{-10-2}\\\\=\dfrac{5}{-12}\\\\=\dfrac{-5}{12}[/tex]
[tex]\sf slope \ of \ the \ perpendicular \ line \ m_1 = \dfrac{-1}{m}= -1 \ \div \dfrac{-5}{12}[/tex]
[tex]\sf = -1 * \dfrac{12}{-5}=\dfrac{12}{5}[/tex]
Equation of the required line: y = mx + b
[tex]y =\dfrac{12}{5}x+b[/tex]
The line passes through (-5 , 10). Substitute in the above equaiton,
[tex]10 =\dfrac{12}{5}*(-5) + b\\\\ 10 = (-12) + b\\\\[/tex]
10 + 12 = b
b = 22
Equation of the line:

Answer:
720 m²
Step-by-step explanation:
The surface area of the prism is the sum of the areas of its 5 surfaces.
Area of triangle= ½ ×base ×height
Area of front face
= ½(6)(8)
= 24 m²
Area of back face= 24 m²
Area of rectangle= length ×breadth
Area of base
= 8(28)
= 224 m²
Area of right surface
= 10(28)
= 280 m²
Area of left surface
= 6(28)
= 168 m²
Total surface area
= 24 +24 +224 +280 +168
= 720 m²

possible?
A. 40,320
B. 10,080
OC. 1,680
D. 70
Answer: 70
Step-by-step explanation:
you would do 8C4
If there are 8 pieces to choose from, there are 1,680 different ways distinct displays are possible.
How many ways k things out of m different things (m ≥ k) can be chosen if order of the chosen things doesn't matter?[tex]^mP_k = k! \times ^mC_k = k! \times \dfrac{m!}{k! \times (m-k)!} = \dfrac{m!}{ (m-k)!}\\\\^mP_k = \dfrac{m!}{ (m-k)!}[/tex]
This is called permutation of k items chosen out of m items (all distinct).
To find the Ways can 8 pieces of art in the front window be arranged in the display window.
Let us use permutation to find the number of ways can 8 pieces of art in the front window be arranged in the display window.
here we have
n= 8
r= 4
substituting the values,
[tex]^nC_r = \dfrac{n!}{ (n-r)!}\\\\^8C_4 = \dfrac{8!}{ (8-4)!}\\\\^8C_4 = \dfrac{8!}{ (4)!}\\\\^8C_4 = 8 \times 7 \times 6\times 5\\\\^8C_4 =1680[/tex]

A graph titled Fast Freddy has time (minutes) on the x-axis and Distance (miles) on the y-axis. A line goes through points (0, 0) and (4, 1). A 2-column table with 3 rows titled Speed Sam. Column 1 is labeled Time (minutes) x with entries 4, 20, 32. Column 2 is labeled Distance (miles) y with entries one-half, 2 and one-half, 4.
Find the slope from the graph and from the table to compare the speeds of two marathon runners.
What is the constant speed of Fast Freddy?
What is the constant speed of Speedy Sam?
Who ran faster?
Using linear function concepts, it is found that:
The constant speed of Fast Freddy is of 0.25 miles per minute.The constant speed of Speedy Sam is of 0.125 miles per minute. Hence, due to the higher speed, Fast Freedy ran faster.What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.For Fast Freedy, we have that he run one mile in four minutes, hence the slope is given by:
mF = 1/4 = 0.25 miles per minute.
The constant speed of Fast Freddy is of 0.25 miles per minute.
For Speedy Sam, when the the time changes by 16 minutes, the distance changes by 2, hence his slope is given by:
mS = 2/16 = 1/8 = 0.125 miles per minute.
The constant speed of Speedy Sam is of 0.125 miles per minute. Hence, due to the higher speed, Fast Freedy ran faster.
