Answer: The answer is 97, because when you add up 42 and 55 you get 97. Then you subtract that by 180 because a triangles angles add up to 180. 180-97=83. Z=83. Z and y are supplementary to eachother, so therefore 180-83= 97. Supplementary means they add up to 180.

I know it is simple, but my mind is overloaded right now. Help would be appreciated

Answers

OK.  Don't blow a fuse.

Remember:  The interior angles of every triangle always add up to 180 degrees.

So ' x ' is whatever you need to add to (60+70) to reach 180.

     60 + 70 = 130 .

Make up the difference between 130 and 180, and you'll have ' x '.

Your gas tank can hold no more than 14.5 gallons of gasoline. On a trip to the grocery store, you use 1.5 gallons of gasoline. Write and solve an inequality that represents the amount of gasoline left in your gas tank.

Answers

Final answer:

Considering a gas tank's full capacity of 14.5 gallons, after using 1.5 gallons, subtract this from the initial amount to find how much gasoline remains. This leaves us with an inequality 0 ≤ G ≤ 13, where G represents the gasoline left in the tank.

Explanation:

The subject of this question is the calculation of quantities in everyday life, specifically in regards to gasoline use for a car. We start with an initial total fuel capacity of 14.5 gallons. We then subtract the amount of fuel used for a trip to the grocery store, which is 1.5 gallons. This subtraction operation shows how much gasoline remains in the tank.

Step-by-step, the solution could be described like this:

  • Establish the maximum capacity of the gas tank, which is given as 14.5 gallons.
  • Account for the fuel used on the trip, in this case, 1.5 gallons.
  • Subtract the used fuel from the tank's capacity. This would be 14.5 gallons - 1.5 gallons = 13 gallons.

Therefore the inequality representing the amount of gasoline left in the gas tank is 0 ≤ G ≤ 13, where G is the amount of gasoline left in the tank.

Mike started a savings account by depositing $9. Each month he deposits more money than the month before. At the end of 41 months, he has saved $9,389.00. How much more does he deposit each month

Answers

We have to calculate how much more money does Mike deposit each month. This can be done using the formula for the arythmetic sequence; S n = n/2 * ( a1 + an ). Here: a 1 = 9, n = 41 and a n = a 1 + ( n-1 ) d = 9 + 40 d. So : 9,389 = 41/2 * ( 9 + 9 + 40 d ); 9,389 = 41 / 2 * ( 18 + 40 d ); 9,389 = 41 * ( 9 + 20 d ) ; 9,389 = 369 + 820 d; 820 d = 9,389 - 369; 820 d = 9,020; d = 9,020 : 820; d = 11. Answer: He deposits $11 more each month.

Answer:

$11.00 or 11

same thing :)

*plug all other answer choices inside formula as d to check your answer*

Step-by-step explanation:

we need to use the arithmetic sequence formula

S_n=(n)/(2) [2a_1+(n-1)d]\n

a_1=9\nn=41\nd=11 \n\nS_4_1=(41)/(2)[ (2)(4)+(41-1)(11)] \n\nS_4_1=(41)/(2) [8+(40)(11)]\n\n\S_4_1=(41)/(2) (18+440)\n\nS_4_1=(41)/(2) (458)\n\nS_4_1=20.5 (458)\n\nS_4_1=9,389

He deposit 11 each month is right because the sum of the series (S_n)  is 9,389 and he saved 9,389 at the end of the 41 months.
