Answer:

Step-by-step explanation:

I can't read the diagram well enough to tell you how exactly this should be done and I've been reprimanded a couple of times for using comments to solve problems, but this much I can tell you.

You need 2 angles

One comes from vertical angles being equal.

the other comes from the other end of the line that is bisected. Be careful to chose this angel. The two angles are equal because the lines are parallel.

Now what you have is ASA which always proves congruency. AAS should never be used if you can avoid it. If you search out AAS on the internet you will find long discussions on why AAS should never be used.

In this case it will work but even if it does, it should be avoided because you may run into questions where there are conditions that make AAS incorrect. Even if you are told it is OK in your lessons, you should not do it.

Answer:

60

Step-by-step explanation:

perimeter (p) = 8 + 17 + 15 = 40

semi-perimeter (s) = p/2 = 20

Area = square root of s(s-a)(s-b)(s-c) where a,b,c are the sides of the triange by Herons formula.

Therefore, area = 20(20-8)(20-15)(20-17) = square root of 3600 = 60

Answer:

87.5%

Step-by-step explanation:

Took the k12 math test

A savings account starts with $231 25. After 8 years of continuous compounding at an interest rate of 87.5% the account has $1850.

Compound interest is a method of calculating the interest charge. In other words, it is the addition of interest on interest.

Compound Interest = P(1+r/n)^rt

A savings account starts with $231 25. After 8 years of continuous compounding at an interest rate the account has $1850.

Compound Interest = P(1+r/n)^rt

[tex]\rm 1850 = 231 25 (1 + r/12)^{96}[/tex]

[tex]\rm 1850 = 231 25 (1 + r/12)^{96}\\\rm 1850 /231 25 = (1 + r/12)^{96}[/tex]

r = 87.5%

Thus, the interest rate percentage is 0.87 rate per year.

Answer:

[tex]a_n=2n[/tex]

Step-by-step explanation:

The given sequence is 2, 4, 6, ....

We need to write an explicit formula for [tex]a_n[/tex]. The firts term is 2, second term is 4 and third term is 6 and so on.

Each term is 2 greater than the term before it. Thus we can write it as follows :

[tex]a_n=2n[/tex]

Where

n = 1,2,3....

Hence, the explicit formula is [tex]a_n=2n[/tex].

Answer:

y-5x-7=0

Step-by-step explanation:

m = -2-3/1-2

m=5

y-y1 = m(x-x1)

y-2=5(x+3)

y-2=5x +5

y-5x-7=0

Answer:

-5<x<9

Step-by-step explanation:

Within a triangle, the greater an angle, the greater the length of opposite side. So, since we know that 42° gives an opposite side of 23, and (3x+15)° gives an opposite side of 21, (3x+15) must be less than 42:

3x+15<42

3x<27

x<9

We also know that the angle (3x+15)° cannot equal zero or less than zero. So find x when 3x+15=0, and note that our value for x must be greater than this:

3x+15=0

3x=-15

x=-5

so, -5<x

Put both parts together to get: -5<x<9

Answer:

25 - ( 9 - 4.3 ) = 25 - 5.3 = 20.7 ●

Answer:

false

Step-by-step explanation:

rewrite this with 4.3 in place of y first

25 - (9 - 4.3) = 20.7

    25 - (4.7) = 20.7

      25 - 4.7 = 20.7

      25 - 4.7 = 20.3

           20.3 ≠ 20.7

Answer: C

Step by Step Explanation: The answer is 660

The number of students in the entire body of 1,200 students who are in favor of changing the school colors is, 660

Any relationship that is always in the same ratio and quantity which vary directly with each other is called the proportional.

We have to given that;

The results of a survey show that 20 of 36 students are in favor of the change.

Now, Let number of students in the entire body of 1,200 students who are in favor of changing the school colors is, x

Hence, We can formulate;

⇒ 20 / 36 = x / 1200

⇒ 5 / 9 = x / 1200

⇒ 1200 × 5 / 9 = x

⇒ x = 6000 / 9

⇒ x = 660

Thus, The number of students in the entire body of 1,200 students who are in favor of changing the school colors is, 660
