Answer:

Step-by-step explanation:

This is an arithmetic sequence with a₁ (first term) = 10.5 and d (common difference) = 11 - 10.5 = 0.5

Explicit formula for arithmetic sequences: aₙ = a₁ + (n - 1) * d

Therefore, aₙ = 10.5 + (n - 1) * 0.5 = 0.5n + 10 so a₂₂ = 0.5 * 22 + 10 = 21.

A theater group made appearances into cities the hotel charge before tax and the second city was 1500 higher than the first the

Svetlanka [38]

Answer:

The hotel charge in each city before tax was $5125 of the first city and $3625 of the second city.

Step-by-step explanation:

Given:

A theater group made appearances into cities the hotel charge before tax and the second city was 1500 higher than the first.

The tax of the first city was 6% and the tax of the second city was 10%.

Total hotel tax paid for two cities with $670.

Now, to find the hotel charge in each city before tax.

Let the hotel charge in first city before tax be $x.$

And the hotel charge in second city before tax be $y.$

So, as the hotel charge of the second city was 1500 higher than the first.

Thus,

$y=x-1500$ ........(1)

And as given, the tax of the first city was 6% and the tax of the second city was 10%, total hotel tax paid for two cities with $670.

6% of $x$ + 10% of $y$ = $670.

$\frac{6x}{100} +\frac{10y}{100} =670$

$0.06x+0.10y=670$

Substituting the value of $y$ from equation (1) we get:

$0.06x+0.10(x-1500)=670$

$0.06x+0.10x-150=670$

$0.16x-150=670$

Adding both sides by 150 we get:

$0.16x=820$

Dividing both sides by 0.16 we get:

$x=5125.$

The hotel charge in first city before tax = $5125.

Now, substituting the value of $x$ in equation (1) we get:

$y=x-1500$

$y=5125-1500$

$y=3625.$

The hotel charge in second city before tax = $3625.

Therefore, the hotel charge in each city before tax was $5125 of the first city and $3625 of the second city.

A holiday meal cost 12.50 a person plus a delivery fee of $30 at we cater. The same meal cost $15 a person with no fee at Good E

4vir4ik [10]

Given :

A holiday meal cost 12.50 a person plus a delivery fee of $30 at we cater.

The same meal cost $15 a person with no fee at Good Eats.

To Find :

When does we cater become the better deal.

Solution :

Let , x is number of order .

Cost at cater , C = 12.5x + 30 .

Cost at Good Eats , G = 15x .

We need to find :

G > C

$15x>12.5x + 30\\\\2.5x>30\\\\x>12$

Therefore, after 12th order cater will be more value for money.

Hence, this is the required solution.

PLEASE HELP!!! PLEASE!!!

Answer:

Average speed = $\frac{(x+y)}{2}$ miles per hour

Step-by-step explanation:

Formula to calculate the average speed of an object is,

Average speed = $\frac{\text{Total distance covered}}{\text{Time taken to cover this distance}}$

If I travel with the speed of x mph for t hours,

Total distance covered = Speed × Time

= $x\times t$

= $xt$ miles

Similarly, if I travel with the speed y mph for t hours,

Total distance covered = $yt$ miles

Total distance covered by me = $(xt+yt)$ miles

Total time taken to cover this distance = $t+t$

= $2t$ hours

Therefore, expression for the average speed will be,

Average speed = $\frac{xt+yt}{2t}$

= $\frac{(x+y)t}{2t}$

= $\frac{x+y}{2}$ miles per hour
