Answer: The equation of the line perpendicular to y = 4x + 3 and passes through the point (-4, -2) is y = -(1/4)x - 3.
Step-by-step explanation: An line perpendicular to perpendicular to the line y = 4x + 3 would have a slope that is the negative inverse of the refernce line. That would make the new line's slope -(1/4), the negative inverse of 4,
We can write the new new as y = -(1/4)x + b. b, the y-intercept, is +3 in the original equation, but it will change for the new line. We can calculate the new y-intercept by using the one point, (-4,-2) that we know is a solution for the equation (it falls on the line).
y = -(1/4)x + b
-2 = -(1/4)(-4) + b
-2 = 1+b
b = -3
The equation of the line perpendicular to y = 4x + 3 and passes through the point (-4, -2) is y = -(1/4)x - 3.

Claudia works at a sweet shop making chocolate-dipped bananas. Sometimes she drops the chocolate-
dipped bananas before she can get them to the freezer. Claudia earns 20 cents for every frozen banana that
she makes. She loses 5 cents for each frozen banana that she drops. Last Wednesday, Claudia dipped 48
frozen bananas, but not all of them made it to the freezer. She earned a total of $7.60. How many bananas
were dropped and how many made it to the freezer? Define your variables and write a system of
equations representing this situation. Solve the system by using either graphing, substitution, or
elimination.

A three-dimensional L-shaped figure is made of two rectangular prisms joined at a right angle. A horizontal rectangular prism has a length of eight inches, a width of two inches, and a height of two inches. A vertical rectangular prism connected at the right end of the other prism has a length of two inches, a width of two inches, and a height of eight inches. What is the total volume of the composite figure?
The total volume of the composite figure is 64 in³.
Volume of a rectangular prismThe volume of a rectangular prism, V = lwh where
l = length, w = width and h = heightVolume of horizontal rectangular prismSince horizontal rectangular prism has a length of eight inches, a width of two inches, and a height of two inches. So,
l = 8 in, w = 2 in and h = 2 in.So, its volume V' = lwh
= 8 in × 2 in × 2in
= 32in³
Volume of vertical rectangular prismSince the vertical rectangular prism connected at the right end of the other prism has a length of two inches, a width of two inches, and a height of eight inches. So,
l = 2 in, w = 2 in and h = 8 in.So, its volume V" = lwh
= 2 in × 2in × 8 in
= 32 in³
Volume of composite figureThe volume of the composite figure V"' = V' + V"
= 32 in³ + 32 in³
= 64 in³
So, the total volume of the composite figure is 64 in³.

Aram has been studying the mathematics behind pinball machines. He made the following diagram of one of his
observations. Determine the measure of the missing angle.
Given:
A diagram of Aram's observations.
To find:
The measure of the missing angle.
Solution:
From the given figure it is clear that the three angles [tex]52^\circ,x^\circ,68^\circ[/tex] lie on a single point and right side of a straight line.
So, the sum of angle [tex]52^\circ,x^\circ,68^\circ[/tex] must be [tex]180^\circ[/tex].
[tex]52^\circ+x^\circ+68^\circ=180^\circ[/tex]
[tex]x^\circ+120^\circ=180^\circ[/tex]
[tex]x^\circ=180^\circ-120^\circ[/tex]
[tex]x^\circ=60^\circ[/tex]
Therefore, the measure of the missing angle is [tex]x^\circ=60^\circ[/tex].

The length of the side AC will be equal to 5.69 cm
What is quadrilateral?A figure consisting of four sides connected together and forming a total angle of 360 degrees is called a quadrilateral.
Given that:-
ABCD is a kite, so AC I DB and DE= EB.
AD = 4 cm BD = 4 cm and CD = 3 cm.
The side AC will be calculated as:-
Since AC is bisecting the line BD so BE = ED and BE = 2 cm and ED = 2 cm. WE have AD = 4 cm so we will calculate AE first by using the Pythagorean theorem.
AE² = AD² - ED²
AE² = 4² - 2²
AE² = 16 - 4 = 12
AE = √12 = 3.46 cm
Similarly, we will find the value of EC.
EC² = 3 ² - 2²
EC² = 9 - 4 = 5
EC = √5 =2.23
WE know that AC = AE + EC
AC = 3.46 + 2.23
AC = 5.69 cm
Therefore the length of the side AC will be equal to 5.69 cm

30$
Answer:
It would be 30$.
Step-by-step explanation:
Lets break this down.
50% off 100 would be 50. 50 is half of 100, therefore we know that 50% is half off of something.
We can either divide 60 by 2, or split 60 in half. In turn, we receive 30.
