Terrell has $2,700 in his checking account and $1500 in his savings account. He
uses his checking account to pay bills, which are $240 each month.
a) In how many months will his checking account balance equal his savings account
balance?
b) If Terrell deposited an additional $720 in his savings account, in how many
months will his balances be the same?
Answer:
1.8 month and they wouldnt
Step-by-step explanation:
brainalist
The number of months when both accounts have the same balance is 5 months. If $720 is deposited each month in the saving account, then the number of months when both accounts have the same balance is 1.25 months.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
Terrell has $2,700 in his financial records and $1500 in his bank account. He utilizes his financial records to take care of bills, which are $240 every month.
Let 'x' be the number of months. Then the equation is given as,
1500 = 2700 - 240 x
240 x = 1200
x = 5 months
Assuming Terrell kept an extra $720 in his bank account. Then the equation is given as,
1500 + 720 x = 2700 - 240 x
960x = 1200
x = 1.25 months
The quantity of months when the two records have a similar equilibrium is 5 months. On the off chance that $720 is kept every month in the saving record, the number of months when the two records have a similar equilibrium is 1.25 months.

Answer:
$53.00
Step-by-step explanation:

250 is the discounted price, 265 is the original price. Take the original oprice divide it by 5 (the number of games Filipe bought).
Answer: 53
Steps:
5x - 15 = 250
5x = 250 + 15
5x = 265
x = 265/5
x = 53
Check:
5x - 15 = 250
5(53) - 15 = 250

Answer:
52 in^2
Step-by-step explanation:
If the diameter = 3 in, then the radius = 1.5 in.
To find the surface area, you need to find the area of the two circle areas (the base and the top of the cylinder) and the "sides" of the cylinder. If you look at the net shape of a cylinder, look at the picture below. That middle region aka the "side" of the cylinder is actually a rectangle. The length of the rectangle is also the circumference of the circle and the width is also the height of the can.
So:
2 * Area of the circle + rectangle = total surface area of the can
= 2(πr^2) + 2πrh
= 2π(1.5^2) + 2π(1.5)(4)
= 2π(2.25) + 12π
= 4.5π + 12π
= 16.5π
≈ 51.8
≈ 52 in^2
If the mean of 5 numbers is 36 , what is the 5 th number if four of the numbers are 27 , 42, 43, and 35
Answer:
33
Step-by-step explanation:
To find the mean of 5 numbers, you add the 5 numbers and divide by 5.
Let the unknown number = x.
(27 + 42 + 43 + 35 + x)/5 = 36
(x + 147)/5 = 36
x + 147 = 180
x = 33

Answer:
241 t-shirt and 49 short
Step-by-step explanation:
lets call shorts x and tshirts y
x+y=290 (first equation)
4x+2y=678 (second equation) { we multiply the price of short with the short so we can get the pieces sold and also with the t-shirt to get the pieces sold)
x=290-y
and substitute it with x in the second equation
4(290-y)+2y=678 then till u get to y=241 (the pieces sold)
290-241=49 (pieces sold)
so as proof 49+241=290 pieces sold
as proof also 4*49=196 price of all shorts sold
2*241=482 price of all t-shirts sold then add them together and u will get 196+482=678$
The afternoon crew at Yummy Yummy Subbys can make a submarine sandwich once every 45 seconds. The evening crew can only make a submarine sandwich once every 50 seconds. If both crews work together, how many seconds will it take them to make 38 submarine sandwiches?
Answer: 900
Step-by-step explanation:
The number of seconds it will take both the crew together to make 38 sandwiches is 900.
What is LCM?The least common multiple that is divisible by both a and b is the smallest positive integer, lowest common multiple, or smallest common multiple of two numbers a and b, generally indicated by LCM.
The time taken by the afternoon crew to make a sandwich is 45 seconds. The time taken by the evening crew to make a sandwich is 50 seconds. Taking the LCM of the timing of the two crew, to know at what time they both will finish making a sandwich together.
LCM of 45 and 50 is 450.
Therefore, the number of sandwiches made by the afternoon crew in 450 seconds is 10, while the number of sandwiches that will be made by the evening crew is 9. Thus, in a time period of 450 seconds, both crews together will make 19 sandwiches.
Now, since it takes 450 seconds to make 19 sandwiches the time it will take to make double the number of sandwiches therefore, 38 sandwiches will also be double.
Hence, the number of seconds it will take both the crew together to make 38 sandwiches is 900.

What is a function?It is defined as a special type of relationship and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have:
[tex]\rm f(x) = x^2-6x-27[/tex] and
[tex]\rm g(x) = x-9[/tex]
[tex]\rm (f+g)x = x^2-6x-27+x-9\\\\(f+g)x = x^2-5x-36[/tex]
[tex]\rm \dfrac{f}{g}(x) = \dfrac{x^2-6x-27}{x-9}\\\\\\rm \dfrac{f}{g}(x) = \dfrac{(x+3)(x-9)}{x-9}\\\\\rm \dfrac{f}{g}(x) = x+3[/tex]
[tex]\rm (f\times g)(x) = (x^2-6x-27)(x-9)\\\\\rm (f\times g)(x) =x^3-15x^2+27x+243[/tex]
[tex]\rm (f-g) = x^2-6x-27-(x-9)\\\\\rm (f-g) =x^2-7x -18[/tex]
Thus, for (x+3) → (f/g)(x), for x^3-15x^2+27x+243 → (f.g)(x), for x^2-5x-36 → (f+g)(x), for x^2-7x -18 → (f-g)(x) represents correct combination.
