Answers

Answer:

<a = 30

<b = 60

<c = 115

Step-by-step explanation:

<a = 30 since they are vertical angles and vertical angles are equal

<a + < b + 90 = 180 since they make a triangle

30 + <b +90 = 180

120 + <b = 180

<b = 180-120

<b = 60

<c + 75 = 180 since they form a straight line

<c = 180-75

<c = 115

Answer:

a=30

b=60

c=105

Step-by-step explanation:

We know a=30 because 30 and a are the same

The middle forms a triangle and triangles are equal to 180

The box indicates that the angle is 90 degrees

180=a+b+90

180=30+90+b

b=60

Angle c is supplementary to 75 so it must equal 180

180=c+75

c=105

What is the value of x?

Answers

Answer:

62 is the answer to your question

one quick way to know the answer is to know that the two opposite interior angles has to add up to the outer external angle, so x + 38 = 100

Answer:

B. 62°

Step-by-step explanation:

First, solve the unknown interior angle. Interior angles and exterior angles add up to 180°.

? + 100 = 180

? = 80

The sum of the angles of a triangle is 180°. Form and solve the following equation.

x + 80 + 38 = 180

x + 118 = 180

x = 62

Answers

Answer:

Step-by-step explanation:

Point slope form is written in

y - y1 = m(x - x1)

Where m is the slope and (x1, y1) is a point on the line.

Looking at the values we have m = 1/2 and x1 = 1, y1 = 4.

Therefore the slope is 1/2 and the point is (1,4)

You have a choice to invest in one of three different college funds to save up for college. You need to save at least $14,000 for your first year. In which of the three accounts do you choose to invest your money given that you have $10,000 to invest and you would like to accrue as much interest as possible?​

Answers

Answer: C) You choose account #2

===================================================

Explanation:

Let's compute the final balance for account 1.

We'll use the compound interest formula

A = P*(1+r/n)^(n*t)

where,

P = principal or amount depositedr = decimal form of the annual interest raten = number of times we compound the interest per yeart = number of years

where in this case

P = 10,000r = 0.035 n = 4 t = 10

So with all that in mind, we get

A = P*(1+r/n)^(n*t)

A = 10,000*(1+0.035/4)^(4*10)

A = 14,169.0883793113

A = 14,169.09

Account #1 gets us $14,169.09 which is over our goal of $14,000

--------------------------

Let's repeat this idea for account 3. I'll get back to account 2 in the next section.

For account 3, we have these inputs

P = 10,000r = 0.032n = 1t = 10

leading to...

A = P*(1+r/n)^(n*t)

A = 10,000*(1+0.032/1)^(1*10)

A = 13,702.4104633564

A = 13,702.41

This isn't larger than 14,000. So we cannot use account 3. The interest rate is too small and needs to be bumped up.

--------------------------

Now let's compute account 2. We'll use the continuously compounded interest formula which is

A = P*e^(rt)

The P, r and t are the same as before. The 'e' is a constant and it's roughly e = 2.718... similar to how pi = 3.14... approximately.

I recommend using the calculator's stored value of 'e' to get as much accuracy as possible.

So,

A = P*e^(rt)

A = 10,000*e^(0.036*10)

A = 14,333.2941456052

A = 14,333.29

This exceeds 14,000 so we can use this account.

Comparing this to account 1's value (14,169.09), we can see that account 2 gets us the most money over the 10 year time period. Not only does account 2 have the higher interest rate, but it also has an infinitely higher compounding frequency as well. These two factors help contribute as to why account 2 beats out account 1.

This is why we should go for account 2.

time did she spend fixing her bicycle?

Answers

Answer:

3 hours 26 minutes

Step-by-step explanation:

26 minutes(9.34am to 10am)+3 hours(10am to 1pm)=3 hours 26 minutes

The total time that she spend fixing her bicycle is 3 hr 26 minutes

Calculating total time

Given the following parameters

Time that Olivia starts fixing bicycle= 9:34 am

Time she finishes = 1pm

The total number of hours spent from 9:34am and 12:34pm is 3 hrs. The remaining minutes to 1 pm is 26 minutes.

Paige earns a 5% commission on all appliance sales plus a base salary of $500 a week. Paige wants to earn $2,500 this week. Paige needs to make _____ in appliance sales this week
A: $100
B: $125
C: $40,000
D: $50,000

Answers

Answer:

C. $40,000

Step-by-step explanation:

Basic salary = $500

Expected earning this week = $2,500

Expected commission on appliance sales = $2,500 - $500 = $2,000

% commission = 5% = 0.05

Appliance sales = $2,000/0.05 = $40,000

2,500-500
= 2000
2000/0.05 = 40,000

All three sides are congruent.

Answers

3 Answers:  Choice A, Choice C, Choice E

=====================================================

Explanation:

Let's go through the answer choices to see which are true and which are false.

A) True. The base angles are the same measure, and they are opposite the congruent sides. Any isosceles triangle has exactly two congruent sides.B) False. This is describing an equilateral triangle (where all three angles are 60 degrees each).C) True. See choice A.D) False. This is describing an equilateral triangle where all sides are the same length. E) True. You can use the SAS (side angle side) congruence theorem to prove that the angle bisector is also the perpendicular bisector. Furthermore, this segment is also a median. This only applies to the vertex angle.

Answer:

The base angles are congruent.

The two sides opposite the base angles are congruent.

Answer:

x = 60

Step-by-step explanation:

The sum of the interior angles of a quadrilateral is 360 degrees.

So if we sum up all the given angles, we would get this equation:

2x + x + 90 + 90 = 360

which simplifies to

3x + 180 = 360

subtract 180 from both sides

3x = 180

divide both sides by 3

x = 60

Answer:

Below!

Step-by-step explanation:

Since all angles in this shape add up to 360, I used this formula to find x

  360 = 90 + 90 + x + 2x

  360 = 180 + 3x

  180 = 3x

Divide both sides by 3

   60 = x

You can check to see if this works

90 + 90 + 60 + 120 = 360

Hope this helps!

Answer:

(- 3, 2 )

Step-by-step explanation:

Given the 2 equations

x + 3y = 3 → (1)

- 2x + 3y = 12 → (2)

Subtract (1 ) from (2) term by term to eliminate y

- 2x - x + (3y - 3y) = 12 - 3

- 3x = 9 ( divide both sides by - 3 )

x = - 3

Substitute x = - 3 into either of the 2 equations and solve for y

Substituting into (1)

- 3 + 3y = 3 ( add 3 to both sides )

3y = 6 ( divide both sides by 3 )

y = 2

solution is (- 3, 2 )
