Two of the angles of a triangle measure 40° and 100°. Classify the triangle

Ksju [112]

Hey there!

All of the given angles of a triangle will always add up to 180 degrees. Therefore, our angle measures are 100, 40, and 40. There are 3 types of triangle classifications based on angles.

Acute: all three angles are less than 90 degrees.

Right: one angle is 90 degrees.

Obtuse: has an angle that is greater than 90 degrees.

As you can see, we have one angle that is greater than 90, which is 100.

Therefore, this is an obtuse triangle.

I hope this helps!

1.Hannah walked the same number of miles each day for 5 days. Let m represent the total number of miles Hannah walked. Write a l

mamaluj [8]

1) Given m represent the total number of miles Hannah walked.

Let us assume Hannah walked x miles each day.

So total number of miles Hannah walked in 5 days is m=5x.

2)Given Jimmy brought 2 books per day and Peter brought 4 books per day.

If d is the number of days the book drive, total number of books they brought

=total number books brought by Jimmy+ total number of books brought by Peter

= 2d+4d = 6d

3) Given that c represent cost of the clothes.

Then 30% discount = 0.3c

Hence cost of the clothes = c-0.3c = 0.7c

4) Given c represent the cost of their meal before tipping.

And tip is 15% of the cost.

Hence tip = 0.15c

Hence total bill = c+0.15c=1.15c

5) Given that Tommy had 40$ in his pocket.

And pair of pants cost 37$ with 10% sales tax.

Hence cost of pants including sales tax = 37+37*0.1 = 40.1$ >40$

Hence Tommy cannot afford the pants with 40$ in his pocket.

For following problems, we should group the like terms together and then simplify.

6) (x+8)+(3x-12) = (x+3x)+8-12 = 4x-4

7) 5x+7-(3x-4) = 5x+7-3x+4 = (5x-3x)+7+4 = 2x+11

8) (x-2)-(-4x+1)=x-2+4x-1 = (x+4x)-2-1 = 5x-3

Modeling Exponential Growth and Decay In Exercises 119 and 120, Find the exponential function

Lubov Fominskaja [6]

Answer:

There is no exponential function passing through (1,1) and (5,5).

Step-by-step explanation:

We have the following exponential function

$y = Ce^{kt}$

The function passes through these two points:

(1,1): This means that when t = 1, y = 1

(5,5): This means that when t = 5, y = 5.

(1,1)

$y = Ce^{kt}$

$Ce^{k} = 1$

$e^{k} = \frac{1}{C}$

(5,5)

$y = Ce^{kt}$

$5Ce^{k} = 1$

$Ce^{k} = \frac{1}{5}$

From above, we have that:

$e^{k} = \frac{1}{C}$

$C\frac{1}{C} = \frac{1}{5}$

$1 = \frac{1}{5}$

1 cannot be equal to 1/5, so this is wrong.

This means that there is no exponential function passing through (1,1) and (5,5).

Suppose that nine-digit Social security numbers are assigned at random. If you randomly select a number, what is the probability

Rina8888 [55]

Answer: 0.3 .

Step-by-step explanation:

The digits in number system = 10 ( 0 to 9)

The total different nine-digit Social security numbers = $10^9$ [By Fundamental counting principle]

$=1,000,000,000$ = 1 billion

Total people in united state = 300 million = 300, 000 ,000

Since each person In US have equal chance to get chosen.

Therefore , if a number is selected randomly , then the probability that it belongs to one of the 300 million people in the United States :-

$=\dfrac{300, 000 ,000}{1,000, 000 ,000}=0.3$

Hence, the required probability is 0.3 .
