Answer:
320 in²
Step-by-step explanation:
Given that Lin has a drawing that has an area of 20 in², since Lin used a scale factor of 4 to increase all sides, therefore the new area would be increased by the following:
Square of scale factor of the side = scale factor of area
4² = scale factor of area
16 = scale factor of area
Multiply the original area by 16
20 × 16 = 320 in²

Answer:
m=1/2
Step-by-step explanation:
y1= 1
y2=6
x1= -10
x2-0
m= slope
m= y2-y1/x2-x1
m=6-1/0 - - 10
m= 6-1/0+10
m=5/10
m=1/2
a helicopter is 14 meters above a canyon it goes down 20 meters then up 5 write a subtraction sentence, how do you know your answer is correct?
Answer:
14 - 20 + 5
14 - 15 = -1
-1
If you take 14 meters and you go down 20 meters that is 14 - 20
Then, if you go up 5 meters, that is 14 - 20 + 5.
So simplify 14 - 20 + 5.
Simplified: 14 - 15
So the answer is -1 meter

Juan's grandmother left him 40 shares of Stock A and 150 shares of Stock B. How
much will he get if stock A sells for $225 a share and stock B sells for $27.25 a share?
Answer:
$13,087.50
Step-by-step explanation:
The sale of the 40 shares of stock A at $225 per share will get Juan ...
40 · $225 = $9000
The sale of the 150 shares of stock B at $27.25 per share will get Juan ...
150 · $27.25 = $4087.50
So, the total Juan will receive from the sale of the stocks will be ...
$9000.00 +4087.50 = $13,087.50

Answer:
Divide both sides by a constant to simplify the equation. Thus the second option.
Step-by-step explanation:
Solve for x:
9 - 10 x = -1
Hint: | Isolate terms with x to the left hand side.
Subtract 9 from both sides:
(9 - 9) - 10 x = -9 - 1
Hint: | Look for the difference of two identical terms.
9 - 9 = 0:
-10 x = -9 - 1
Hint: | Evaluate -9 - 1.
-9 - 1 = -10:
-10 x = -10
Hint: | Divide both sides by a constant to simplify the equation.
Divide both sides of -10 x = -10 by -10:
(-10 x)/(-10) = (-10)/(-10)
Hint: | Any nonzero number divided by itself is one.
(-10)/(-10) = 1:
x = (-10)/(-10)
Hint: | Any nonzero number divided by itself is one.
(-10)/(-10) = 1:

The total length of three boards is 7/8 of a yard. The length of two of the boards are 1/4 of a yard and 3/16 of a yard. What is the length of the third board.
Answer:
7/16 of a yard
Step-by-step explanation:
Let's put the boards to the same denominator so it's easier.
Let's go with a denominator of 16
1/4= 4/16
7/8= 14/16
3/16 stays the same.
So, 4/16+3/16+x=14/16
7/16+x=14/16
x=7/16 of a yard, the length of the 3rd board.
what is the equation of the line that passes through (6,4) and (4,1)
Answer:
y = 3/2*x - 5
Step-by-step explanation:
Lets say that P1=(6,4) and P2=(4,1) and that the form of the equation must be y=m*x+b where m is the slope and b the independent variable. Then having two given points we can use the slope formula to find the slope value as:
P1=(x1,y1) and P2=(x2,y2)
slope formula ---> m=(y2-y1)/(x2-x1)
Replacing the given points ---> m=(1-4)/(4-6) = 3/2
then replacing the slope value obtained:
y = 3/2*x + b
Now lets find the value of b. For this we have to replace in the equation a point it can be P1 or P2, i will replace P2:
1 = 3/2*4 + b
1 = 6 + b
1 - 6 = b
-5 = b
therefore the line equation is:
y = 3/2*x - 5

How to find a rational function given 2 vertical asymptotes and an X intercept?
It’s question 20 by the way
Answer:
[tex]\frac{x-4}{(x+3)(x-5)}[/tex]
Step-by-step explanation:
Since the rational function has vertical asymptotes at -3, and 5, the denominator must equal 0 when x is -3 or 5. Therefore, the denominator must be:
(x+3)(x-5)
Now, to make the x-intercept at (4, 0), the numerator must be equal to 0 when x is 4. Therefore, the numerator must be:
x-4
Therefore, that rational function is:

write the equation to solve for x 3x + 21 6x - 60 please help i was given 3x+21=6x-60 thats wrong can someone please help richard u are amazing wish i could message u u can me
Answer:
3x + 21 = 6x - 60
Step-by-step explanation:
parallel angles are equal
3x + 21 = 6x - 60
combine similar terms:
3x - 6x = -60 - 21
-3x = -81
x = 81/3
x = 27
now, plugin the value of x=27 back into the equation to get the angle:
= 3x + 21
= 3(27) + 21
= 102
= 6x - 60
= 6(27) - 60
= 102
as you noticed, both values are equal 102 = 102 because its a parallel angles
so the equation is 3x + 21 = 6x - 60

Laura deposits $2,000 in an account that has an annual interest rate of 1.96%,
compounded monthly. How much interest will she earn at the end of 1 month?
Round to the nearest cent. *
Answer:
$3.23
Step-by-step explanation:
Given that,
Principal, P = $2,000
Rate of interest, r = 1.96%
Tie, n = 1 month = (1/12) years
The formula of compound interest is given by :
[tex]CI=P[(1+\dfrac{R}{100})^n-1]\\\\CI=2000\times [(1+\dfrac{1.96}{100})^{1/12}-1]\\\\CI=3.23[/tex]
So, the interest will she earn at the end of 1 month is $3.23
The amount she earns at the end of 1 month is 200,326cents
The formula for calculating the compound amount is given as:
A = P(1 + r/n)^ntr is the raten is the compounding timet is the timeA = 2000(1 + 0.0196/12)^(12*1/12)
A = 2000 (1+0.00163)^1
A = 2000(1.00163)
A = $2,003.26
Hence the amount she earns at the end of 1 month is 200,326cents

A piece of Plexiglas has a width which is 5 centimeters shorter than its length. What represents the area of the Plexiglas, in terms of its length (L)?
Answer: x*(x-5)
Step-by-step explanation:
Plexiglass is a cuboid
which means that the area would be l*w
in the question it states that the width is 5 cm shorter than the length
since we dont know the values
we represent them as x
so using l*w
we write x*(x-5)
