Answer:

Step-by-step explanation:

50x=30x+100

The equation is 100 + 30m = 50m and the no. of months for which total cost of both the gyms will be same is 5 months.

A linear equation is an algebraic equation in which a variable has a highest degree of 1.

According to the given question At Work-It-Out, a gym membership is $50 per month with no registration fee and At Get Fit, the registration fee is $100 and membership costs $30 per month.

Given no. of months is m.

∴ 50m = 30m + 100

50m - 30m = 100.

20m = 100

m = 5.

The total number of books that we had in out bookcase when we were 11 years old was 2,187 books.

Suppose the initial term of a geometric sequence is [tex]a[/tex]

and the term by which we multiply the previous term to get the next term is [tex]r[/tex]

Then the sequence would look like

[tex]a, ar, ar^2, ar^3, \cdots[/tex]

(till the terms to which it is defined)

Thus, the nth term of such sequence would be

[tex]T_n = ar^{n-1}[/tex] (you can easily predict this formula, as for nth term, the multiple r would've multiplied with initial terms n-1 times).

Lets suppose its initial term is  [tex]a[/tex] , multiplication factor is  [tex]r[/tex]

and let it has total n terms, then, its sum is given as:

[tex]S_n = \dfrac{a(r^n-1)}{r-1}[/tex]

(sum till nth term)

For this case the initial number of books (2) is multiplied by 3 each year.

So we got:

a = 2,

r = 3

Since a = 2 was for age 5, and  if we take age 5 at 1st position, then age 11 is at the 7th position.

The number of books we read at each age is a geometric sequence with initial term 2 and multiplication factor 3.

The sum of its term(which would make it geometric series) will give the total number of books we will have.

Since age 11 is at 7th position, so n = 7

Thus, the total number of books we had in the bookcase when we were 11 years old is:

[tex]S_n = \dfrac{a(r^n-1)}{r-1}\\\\S_7 = \dfrac{2((3)^7-1)}{3-1} = 2187[/tex]

We could've derived it without formula as:

Their sum is 2187.

Thus, the number of books that we had in out bookcase when we were 11 years old was 2187 books.

Answer:

1. The capacity of the water tank = 240 litres

2. So it will take 180 litres to fill it three quarters full.

Step-by-step explanation:

Dimensions of a water tank:

1 Meter=100 CM

Length (l) = 100 cm,

wide (w) = 40 cm,

Depth (h)= 60 cm,

Volume of the tank (V)

LWH

100 cm × 40 cm × 60 cm

240,000 cm³

The capacity of the water tank = 240,000 cm³ / 240 litres

(240,000*3)/4 = 180,000 cm3

So it will take 180 litres to fill it three quarters full.

Answer:

3. Do Δy/Δx

Step-by-step explanation:

Do 10/3, which is an estimate. You get an answer of 3.3. Intuitively this makes sense because the slope is a constant positive value. And 1/3 is way too small of a number to describe the steepness shown

Or actually, do 3/1 because that would give the slope from x=0 to x=1. Since the slope is constant, that answer will apply for every single point on the function

Answer:

it is D c= 180 + 50h + 20p

Step-by-step explanation:

c is the total cost and the boat is 180 but for additional hour it would be +$50

now the first four passenger is free but if another person comes on then it would be +$20 hope this help

The linear equation which describes the total cost of the rental is           c = 180 + 50h + 20p

The correct option is an option (D)

"It is an equation in which the highest power of the variable is always 1."

For given example,

The boat rental has a flat fee of $180 for up to three hours.

Fixed rental cost = 180                       ...............(1)

The boat rental has $50 per hour for each additional hour.

Let, h is each additional hour (over 3)

So, the rental cost for each additional hour = 50h               .............(2)

The first four passengers are included in this cost, but $20 is charged for each additional passenger.

Here, p is each additional passenger (over 4)

So, the rental cost for each additional passenger = 20p         ..................(3)

From (1), (2) and (3),

the required linear equation would be,

c = 180 + 50h + 20p

Therefore, the linear equation which describes the total cost of the rental is c = 180 + 50h + 20p

The correct option is an option (D).

Answer:

B (3,6)

Step-by-step explanation:

y = x + 3

then we will use this y to substitute the other y

4x + y = 18

4x + (x +3) = 18

4x + x + 3 = 18

5x = 18 - 3

5x = 15

x = 15/5 = 3

then we can find the value of y

y = x + 3 = 3 + 3 = 6

Answer:

a. 4

b. 10

Step-by-step explanation:

A. If the math department buys 60 textbooks, which are $89 each, we need to multiply 60 by $89 to get the amount that the textbooks will cost. This gives us $5340. Since the math department has $7200 to spend, we subtract 5340 from 7200. This gives us $1860 that the math department has left to spend on laptops.  Since the laptops cost $395 each, and we have $1860 to spend, we divide 1860 by 395 to figure out how many laptops they can buy. This is 4.7. Since you can't buy 0.7 of a laptop, they can only buy 4 laptops. The final answer is 4.

B. The math department has $7200 to spend and buys 35 textbooks, which are $89 each. Multiply 35 by 89. This is $3115. Subtract this from $7200 to see how much the department has left to spend. The math department now has only $4085 to spend on laptops, which are $395 each. Divide 4085 by 395. This gives us 10.3. We can't buy 0.3 of a laptop, so they can only buy 10 laptops. The answer is 10.

Answer:

A:$7200-$5340

=$1860

They can buy 4 laptops which will cost $1580 and leave you with $280

B: 35 textbooks will cost $3115, which will leave us with $4085, so we can get 10 laptops
