simplify the following 7 + 6 - 9 (- 2) + (- 3)​

Answer:

20,30,40,50,60

Step-by-step explanation:

The sequence is given by the relation as follows :

[tex]a_n=10n+10[/tex]

First term, n = 1

[tex]a_1=10(1)+10=20[/tex]

Second term, n = 2

[tex]a_2=10(2)+10=30[/tex]

Third term, n =3

[tex]a_3=10(3)+10=40[/tex]

Fourth term, n = 4

[tex]a_4=10(4)+10=50[/tex]

Fifth term, n = 5

[tex]a_5=10(5)+10=60[/tex]

So, the first five terms of the sequence are 20,30,40,50,60

i think its (x , y) -> (x + 9, y - 9)

Answer:

74 or 73

Step-by-step explanation:

We are going to assume that the show is sold out.  If 66 student tickets were sold, we only have 74 adult tickets to sell.  Based on that information, we then have to use an inequality to find out if the number of adult tickets we have to sell to meet our money requirements is more than the amount of seating we have left after 66 seats were taken by students.  Our inequality looks like this:

5.50(66) + 7.50(a) ≥ 910 and

363 + 7.50a ≥ 910 and

7.50a ≥ 547 so

a ≥ 73

In order to meet our money requirement, we have to sell 73 adult tickets.  Since we have 74 seats left, we are good.

Answer:

The third one

Step-by-step explanation:

Answer:

Step-by-step explanation:

The money in the account had increased by 29.5%.

This increase in dollars is:

= Amount in account * percentage increase

= 5,800 * 29.5%

= 5,800 * 0.295

= $1,711

The total in his account was therefore:

= Amount invested + increase

= 5,800 + 1,711

= $7,511

Answer:

Net operating cash flow= $459

Step-by-step explanation:

Giving the following information:

Your firm has net income of $329 on total sales of $1,340. Costs are $740 and depreciation is $130. The tax rate is 30 percent. T

To calculate the operating cash flow, we need to use the following structure:

Sales= 1,340

Costs= (740)

Gross income= 600

Depreciation= (130)

EBIT= 470

Tax= (470*0.3)= (141)

Depreciation= 130

Net operating cash flow= $459

Answer:

so far i got A and C

Step-by-step explanation:

if its incorrect im sorry

Pythagoras is the sum of the square of two sides is equal to the square of the longest side. Then the acute angle of the given triangle is 28.07 degrees.

It is a type of triangle in which one angle is 90 degrees and it follows the Pythagoras theorem and we can use the trigonometry function.

A triangle has sides with lengths 8, 15, and 17.

By Pythagoras theorem, we have

  H² =  P² + B²

 17² = 8² + 15²

289 = 64 + 225

289 = 289

The dimension of the triangle satisfies the Pythagoras theorem. Hence the triangle is a right-angle triangle.

Then the acute angle will be

[tex]\rm \theta =Sin ^{-1} \dfrac{8}{17}\\\\\theta = 28.07^o[/tex]

Thus, the acute angle of the given triangle is 28.07 degrees.

Answer:

-1212 feet/min * 412 min = -499314 feet

Step-by-step explanation:

if you have a speed, or in this case velocity since the measurement has a definite direction,  and time you can multiply them together to get the distance.  Some easy examples, 10 feet per second for 1 second is 10 feet, hopefully that logically makes sense as well.  i you are going 10 feet in 1 second, then after 1 second you went 10 feet.  after 2 seconds it's 20 seconds and so on

Here we have -1212 feet per minute for 412 minutes.  just to establish things, 1 minute would be -1212 feet, here the negative means below the surface, sometimes measurements will have that.  Anyway, 2 minutes would get -2424, and so on.  So it should make sense to multiply them.

-1212 * 412 = -499314

With units, you also have to pay attention to what might cancel out.  You treat different units like variables.  so -1212feet per minute looks like -1212 feet/min where feet and min are basically variables.  Similarly 412 minutes is 412 min.  So if you picture multiplying these, you get -1212 feet/min * 412 min.  In this scenario the mins cancel each other out, since everything s being multiplied.  so like if you had x/y * y you would just get x, or 2/3 * 3 gets just 2.  So this is another way to know what to multiply by.

feet/min has min in the denominator and we want feet, so we need to multiply by something that just has min as its units.  Anyway, that let's you know it's -499314 feet

The drivers change in elevation is 499,344 feet in 412 minutes

Given:

Distance travelled per minute = −1212 feet

Time travelled = 412 minutes

Change in elevation = Distance travelled per minute × Time travelled

= −1212 feet per minute × 412 minutes

= 499,344 feet

Therefore, the drivers change in elevation is 499,344 feet in 412 minutes
