Finance charge is: d.) $69.25.

<h3>Finance charge</h3>

Using this formula

Finance charge=(Monthly payment× Number of payment)-(Purchase price-Down payment)

Let plug in the formula

Finance charge=($22.50×12)-($225.75-$25)

Finance charge=$270-$200.75

Finance charge=$69.25

Therefore the Finance charge is: d.) $69.25.

A certain type of concrete mix is designed to withstand 3000 pounds per square inch (psi) of pressure. The concrete is poured i

velikii [3]

Answer:

Step-by-step explanation:

Given the data representation of the strength of nine randomly selected casts (in psi) as 3960, 4090, 3200, 3100, 2940, 3830, 4090, 4040, 3780.

MEAN

Mean is the average of the samples

$\overline x = \frac{\sum Xi}{N}$

$\sum Xi$ is thw sum of the given data

N is the sample size

$\overline x$ is the mean

$\overline x = \frac{3960+4090+3200+3100+2940+3830+4090+4040+3780}{9}\\\\\overline x = \frac{33,030}{9}\\ \\\overline x = 3,670psi$

Hence the mean of the data is 3,670psi

MEDIAN

Median is the value at the middle of the data after rearrangement.

On rearranging in ascending order

2940, 3100, 3200, 3,780) 3,830 (3,960, 4040, 4090, 4090

It can be seen that the middle value is 3860. Hence the median of the data is 3860psi.

MODE

Mode is the most occurring data in the dataset. It is the data with the highest frequency. From the data, it can be seen that the only data occurring most (twice) is 4090, hence the modal value is 4090psi

A. Find the length of the mid segment of an equilateral triangle with side lengths of 12.5 cm.

boyakko [2]

Answer:

A) The length of the mid-segment is 6.25 cm

B) The length of AT = 33 units

C) The value of x is 3

Step-by-step explanation:

A) Find the length of the mid segment of an equilateral triangle with side lengths of 12.5 cm

<u>Solution:</u>

A mid segment of a triangle is a segment connecting the midpoints of two sides of a triangle. This segment has two special properties. It is always parallel to the third side, and the length of the mid segment is half the length of the third side.

This is an equilateral triangle with side lengths 12.5cm

The length of the mid segment = 1/2 the length of the third side.

The length of the mid segment = 1/2 * 12.5

The length of the mid segment = 6.25 cm

B) Given that UT is the perpendicular bisector of AB, where T is on AB, find the length of AT given AT = 3x +6 and TB = 42 - x

<u>Solution:</u>

UT is the perpendicular bisector of AB

T lies on AB

AT = BT

3x+6 = 42-x

Combine the like terms:

3x+x=42-6

4x= 36

Divide both sides by 4

4x/4 = 36/4

x= 9

Now plug the value of x in AT= 3x+6.

=3(9)+6

=27+6

=33

The length of AT = 33 units.

C) Given angle ABC has angle bisector for BD, where AB = CB, find the value of x if AD = 5x + 10 and DC = 28 - x.

<u>Solution:</u>

In Δ ABC

AB = BC

Δ ABC is an isosceles triangle

BD bisects angle ABC

AC is the opposite side of the vertex B

BD bisects the side AC at D

AD=CD

AD=5x+10

CD= 28-x

Equate both the equations:

5x+10 = 28-x

Combine the like terms:

5x+x=28-10

6x=18

Divide both sides by 6

6x/6 = 18/6

x= 3

Thus the value of x is 3....
