The rectangle on the right is a scaled copy of the rectangle on the left. Identify the scale factor. Express your answer as a whole number or fraction in simplest form.
Scale factor is [tex]\frac{14}{21}[/tex].
What is a scale factor?A scale factor in math 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.
Given
The rectangle on the right is a scaled copy of the rectangle on the left.
[tex]\frac{42}{63}[/tex] and 15 ÷ [tex]\frac{45}{2}[/tex]
[tex]\frac{42}{63}[/tex]
Rationalizing [tex]\frac{42}{63}[/tex] by 45
= [tex]\frac{42(45)}{63(45)}[/tex]
= [tex]\frac{1890}{2835}[/tex]
15 ÷ [tex]\frac{45}{2}[/tex]
Rationalizing 15 ÷ [tex]\frac{45}{2}[/tex] by 63
= [tex]\frac{30(63)}{45(63)}[/tex]
= [tex]\frac{1890}{2835}[/tex]
If we want to find the scale factor we have to equal the proportions of two rectangles.
∴ Scale factor = [tex]\frac{1890}{2835}[/tex] = [tex]\frac{14}{21}[/tex]
Hence, scale factor is [tex]\frac{14}{21}[/tex].

Answer:
see explanation
Step-by-step explanation:
Using the identities
tanx = [tex]\frac{sinx}{cosx}[/tex] , cotx = [tex]\frac{cosx}{sinx}[/tex]
Consider the left side
[tex]\frac{tanx}{tanx+cotx}[/tex]
= [tex]\frac{\frac{sinx}{cosx} }{\frac{sinx}{cosx}+\frac{cosx}{sinx} }[/tex]
= [tex]\frac{\frac{sinx}{cosx} }{\frac{sin^2x+cos^2x}{cosxsinx} }[/tex]
= [tex]\frac{\frac{sinx}{cosx} }{\frac{1}{cosxsinx} }[/tex]
= [tex]\frac{sinx}{cosx}[/tex] × [tex]\frac{cosxsinx}{1}[/tex] ← cancel cosx on numerator/ denominator
= sin²x

if the simple answer interest on 2,000 for 10 years is 1,600, then what is the interest rate
Answer:
8%
Step-by-step explanation:
Solving our equation
r = 1600 / ( 2000 × 10 ) = 0.08
r = 0.08
converting r decimal to a percentage
R = 0.08 * 100 = 8%/year
The interest rate required to
accumulate simple interest of $ 1,600.00
from a principal of $ 2,000.00
over 10 years is 8% per year.

(Only the number)
Answer:
14
Step-by-step explanation:
Answer:
the answer is X = 14
Step-by-step explanation:
So you need to single out the X
You do this by doing the opposite of X,
right now X is being multiplied by 14
The opposite of Multiplaction is division
That means you divide X by 14
But dont forget, what you do one side you do to the other.
This means you also Divide 196 by 14
196 ÷ 14 = 14
meaning X = 14

In a bag there are blue sweets, red sweets and yellow sweets. The number of blue sweets is four times the number of yellow sweets. The number of red sweets is half the number of yellow sweets. Find the percentage of sweets in the bag that are yellow.
Answer:
18.18%
Step-by-step explanation:
The percentage of sweets in the bag that are yellow is as follows:
Let us assume the number of yellow sweets be x
So for number of blue sweets be 4x
And, the number of red sweets be 0.5x
So it could be written as
Blue Red Yellow
4 0.5 1
8 1 2
So for yellow, the percentage is
= 2 ÷ (8 + 1 + 2)
= 2 ÷ 11
= 18.18%

2. Find the vector equations of the following lines:
a. A=(6,5,7),m=2i+5j–k
b. A=(8,6,2),B=(3,4,1)
Answer:
a) The vector equation
[tex]AB^{-} = -4i^{-} -0j^{-} -8k^{-}[/tex]
b) The vector equation
[tex]AB^{-} = -5i^{-} -2j^{-} -k^{-}[/tex]
Step-by-step explanation:
Step(i):-
a)
Given that the points are A( 6,5,7) and B = m = 2i+5j-k
OA = 6i+5j+7k and OB = 2i+5j-k
AB = OB-OA
= 2i+5j-k - (6i+5j+7k)
= 2i -6i +5j-5j-k-7k
= [tex]-4i^{-} -0j^{-} -8k^{-}[/tex]
b)
Given that the points are A( 8,6,2) and B = (3,4,1)
OA = 8i+6j+2k and OB = 3i+4j+k
AB = OB-OA
= 3i+4j+k -(8i+6j+2k)
= 3i -8i +4j-6j+k-2k
= [tex]-5i^{-} -2j^{-} -k^{-}[/tex]

Answer:
5the length of the expanded segment is 5 times the original lengthStep-by-step explanation:
We have to assume that the image of B is the large dot at upper right. We further have to assume that the distance between dots on the line segment is equal to CB.
The scale factor multiplies the distance from C. That distance has been multiplied by 5, so the scale factor is 5.
what is 44 > 7+s + 26
Answer:
s<11
Step-by-step explanation:
44>7+s+26
Switch sides:
7+s+26<44
Group like terms:
s+7+26<44
Add the numbers:7+26=33
s+33<44
Subtract 33 from both sides:
s+33-33<44-33
Simplify:
s<11

Step-by-step explanation:
slope intercept form is y=mx+b
where m is the slope and b is the y-intercept
You already know that the slope is 2/3 and the intercept is -1 so all you have to do is plug it in
y=2/3x-1
