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

Thus, the cost of purchase in October is $3705.

The distance between the two parallel lines is 26 units

Parallel lines are lines that do not meet or intersect.

If y = mx +c as the equation of a straight line

For the line y = -5x

comparing with the standard equation of a line,

y = -5x has no y-intercept, so the coordinates of the point is (0,0)

For the second line y = -5x + 26

comparing with the standard equation

The y-intercept is 26, which means the coordinates of the point is (0, 26)

The distance between these two points is the distance between the two lines.

Formula for distance between two point,

D = [tex]\sqrt{(y_{2} -y_{1}) ^{2} + (x_{2} - x_{1}) ^{2} }[/tex]

D = [tex]\sqrt{(26-0)^{2} + (0-0)^{2} }[/tex]

D = 26 units

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.

By SAS rule, triangle DAB is congruent to triangle DCB

If two shapes are similar in size and shape, they are congruent. We can also state that if two shapes are congruent, then their mirror images are identical. If and only if two angles have equal measurements, they are said to be congruent. If and only if two segments have equal amounts of each, they are congruent. If and only if all of the corresponding angles and sides are congruent, two triangles are said to be congruent.

Given data

BD bisects ∠ABC

BD bisects ∠ADC

In ,Triangle DAB and triangle DCB

DA = DC (Given)

∠DAB=∠DCB (BD bisects ∠ABC)

Step-by-step explanation: use your fingers lol

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.

In mathematics, particularly in statistics, there are various kinds of means. Each mean is used to summarize a certain set of data, frequently to help determine the overall significance of a particular data set. 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. When a data collection is ranked from least to greatest, the median is the midpoint number. The number that appears most frequently in a set of data is called the mode.

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
