What are angles?An angle is a figure in Euclidean geometry made up of two rays that share a common endpoint and are referred to as the angle's sides and vertex, respectively. Angles created by two rays are in the plane where the rays are located. The meeting of two planes also creates angles. We refer to these as dihedral angles. Based on the measurement, there are different kinds of angles in geometry. The names of fundamental angles include acute, obtuse, right, straight, reflex, and full rotation.So, the value of x will be:
∠BCE = 5x° and ∠ECD = 40°, and we can see in the diagram that the ∠BCD = 90°.Then, the equation formed will be:
∠BCE + ∠ECD = ∠BCD 5x° + 40° = 90°5x° = 90 - 405x° = 50x = 50/5x = 10So, ∠BCE = 5x° ⇒ 5(10) = 50°.
Therefore, the value of x in the angle ∠BCE is 10 so the measure of ∠BCE is 50°.

Jon used a gift card to pay for an $17 shirt.The remaining balance on the card is $31.Write and solve an equation that representsthis.
Answer
The initial amount on Jon's giftcard is $48.
Explanation
Let the initial amount on Jon's gift card be x dollars.
Jon pays $17 for a shirt using the gift card and the remaining balance was $31.
That is, the equation representing this is
x - 17 = 31
To solve this, we add 17 to both sides
x - 17 + 17 = 31 + 17
x = 48 dollars
The initial amount on Jon's giftcard is $48.
Hope this Helps!!!
Good evening,
Answer: x-17=31 is the equation you're looking for meanwhile its result is x=48
Explanations: Jon spent $18 after having $31 on the card so they're spending money off the card, therefore the equation you're loooking for is x-17=31. In order to solve it add 17 to the other side of the equation such as:
x-17=31 ; x=31+17 ; x=48

familes.
After further examination, the value of 12 is removed for having been recorded in
error. The box plot represents the distribution of the same data set, but with the
maximum, 12, removed.
The median is 2 children for both plots.
a. Explain why the median remains the same when 12 was removed from the data
set.
b. When 12 is removed from the data set, does mean remain the same? Explain

It should be noted that the median remains the same because removing an extreme value from a data set will not have much effect on the median.
What is meant by Statistical data?Statistical data established on the minimum, first quartile, median, third quartile, and maximum exist shown graphically in a box plot.
The box plot represents the number of kids in 30 distinct households in accordance with the families, and the value of 12 is subtracted for inaccuracy.
Therefore, if there exist two kids in the median for both plots when 12 stood eliminated from the data set, it remained unchanged.
In conclusion, the median stays exact because removing an extreme value from a data set will not have much effect on the median.

What is Compound Interest ?
Compound interest, also known as interest on principal and interest, is the practice of adding interest to the principal amount of a loan or deposit. Reinvesting interest, or adding it to the lent capital rather than paying it out or seeking repayment from the borrower, results in interest being received on the principal amount plus previously collected interest in the next period.
Formula used,
A=P(1+r/n)^nt
A = ending amount
P = principal amount(beginning amount)
n = time period
r = rate of interest
Given,
A = $350000
p = $250000
r = 2.04% or 0.0204
n = 12 months
Now, put these values in given formula
350000 = 250000(1 + 0.0204/12)^12t
= 250000 * 1.0017^12t
350000/250000 = 1.0017^12t
1.4 = 1.0017^12t
Take log on both the sides,
㏑(1.0017^12t) = ㏑(1.4)
12t * ㏑(1.0017) = ㏑(1.4)
12t * 0.0017 = 0.3365
t = 0.3365 / 0.0204
t = 16.5 years
Therefore, Shannon will take time 16.5 years to have $350000

The angel L in the triangle JKL is measured as 52 degree.
What is triangle?
A triangle in geometry is a three-sided polygon with three edges and three vertices. The fact that a triangle's internal angles add up to 180 degrees is its most crucial characteristic. This characteristic is known as the triangle's angle sum property.
Given in the question,
∠J = (8x+6)°
∠K = (2x+2)°
∠L = (4x+4)°
We know that, the sum of the all angles in triangle is 180°
So, in triangle JKL
∠J + ∠K + ∠L = 180
Putting the values from the question. we get,
(8x+6) + (2x+2) + (4x+4) = 180
14x + 12 = 180
(180 - 12)/14 = x
x = 12
Putting the value of x in given value of angle L.
∠L = 4x+4
∠L = 4(12)+4
∠L = 48 + 4
∠L = 52°
Hence the angle L is measured as 52 degrees.

The telephone company purchased 95 yards of wire for $1,235 in September. They plan on making a purchase of 285 yards in October. How much will the October purchase cost?
285 yards of wire purchased in October will cost $3705.
We will use unitary method for calculation.
The cost of one yard of wire = total cost ÷ length of wire × unit length
Cost of one yard of wire = 1235 ÷ 95 × 1
Performing division on Right Hand Side of the equation
Cost of one yard of wire = $13
Now calculating the cost for purchase of 285 yards of wire in October.
Cost of wire in October = 285 × 13
Performing multiplication on Right Hand Side of the equation
Cost of wire in October = $3705

When the plane reaches an altitude of 2,000 ft temperature will be 59.3F
What is altitude?The height of a thing above the surface of a planet or natural satellite, like the sea or land is known as altitude.A distance measurement between a reference datum and a point or object, typically in the vertical or "up" direction, is known as altitude, height, or depth.
Although the term "altitude" is frequently used to refer to a location's height above sea level, the term "elevation" is frequently preferred in the context of geography. The term "depth" often refers to vertical distance measurements taken in the "down" direction.
For every 1000 ft there is a drop of 1.2 Fahrenheit
∴ for 2000ft drop in temperature of 2×1.2=2.4F

Two easy steps can be used to determine the mean, or average, of a set of data: Add up all of the values to get the sum. Divide the total by the total number of values in the data collection. A data set's mean (average) is determined by summing all of the numbers in the set, then dividing by the total number of values in the set.

Jimmy is buying balloons and party hats for his little sister’s birthday party. The party store charges $1.50 for each bag of balloons and $6.00 for each package of hats. Which of the following equations could be used to determine different combinations of b bags of balloons and h packages of party hats that he could buy for a total of $24 A.) b+h=24
B.) (1.50+6.00)(b+h)=24
C.) 1.50b+6.00h=24
D.) 6.00b+1.50h=24
Please provide how you did it so I can understand
Answer:
The answer is C.
Step-by-step explanation:
Since the party store charges $1.50 for each bag of balloons, the total price depends on how many bags of balloons Jimmy purchases. So to represent that amount we use the variable given, b. To represent that we can do 1.50b. If we substitute any positive number for b it could look something like this:
(1.50)(1) or 1.50 × 2.
In addition to this, they also sell packages for $6.00 each. We do the same as with the balloons and use the variable h to represent the number of packages Jimmy buys.
We already know that he spends $24 in total but we do not know how many of each item he bought. So we would represent the unit rate price × the variable (or the unknown number of items) of the balloons + the unit rate price and the unknown number of the party hats.
1.50b + 6.00h = 24.
Please let me know if you need additional help!
