We want to see which offer is the best one to buy 40 batteries, by using algebra we will see that the best offer is offer-B

<h3>How to find the best offer?</h3>

Here we just need to see which would be the cost of 40 batteries which each offer.

For offer-A, a pack of 4 costs £2.52 and we have 1/3 off.

For 40 batteries the cost will be 10 times the above quantity, we get:

10* £2.52 =  £25.20

But there is a 1/3 off, so the cost would be 2/3 of the above quantity:

£25.20*(2/3) = £16.80

For offer-B we know that a pack of 5 costs £2.75, so you need to buy 8 of these. And for each 3 you get one free, so you need to buy 6 (and get 2 free ones). The cost of 6 of these is:

6*£2.75 = $16.50

From this, we can conclude that offer-B is the best one.

Vesnalui [34]

Answer:

The amount of down payment needed to qualify for the loan is $ 4,763.90  

Step-by-step explanation:

The question stated that the private mortgage insurance finances 95% of the loan which is the same as the 95% of the value of the home the borrower have in mind.

Availability of 95% mortgage financing implies that the borrower needs to make a down payment of the remaining 5%.

As a result,the borrower would make a down payment of $4,763.90  ($95,278*5%)

A cargo plane flew roundtrip from Smithtown to Johnsville. It took one hour less time to get there than it did to get back. The
iren [92.7K]

Answer:

13 hours

Step-by-step explanation:

Average speed = Distance traveled / time taken

                   ⇒ Distance = Average speed × Time

                                     d = s × t

For the first trip;

Average speed = 280 mph

                          d₁ = 280t₁                    ------(1)

where;

d₁ is the distance covered to get to the destination

t₁ is the time taken to get to the destination

For the second trip;

Average speed = 240 mph

                           d₂= 240t₂                     ------(2)

where;

d₂ is the distance covered on the way back

t₂ is the time taken on the way back

The trip is the same distance to and fro. Therefore,

                           d₁ = d₂                              

Substituting the equation for d₁ and d₂

                          280t₁ = 240t₂              ------(3)

It took one hour less time to get there than it did to get back, then,

                                 t₁ = t₂ - 1

                                 t₂ = t₁ + 1                ------(4)

Substituting equation (4) into  equation (3)

                               280t₁ = 240(t₁ + 1)

                               280t₁ = 240t₁ + 240

                               280t₁ - 240t₁ = 240

                               40t₁ = 240

                                   t₁ = 240/40

                                   t₁ = 6 hours

From equation (4)

                                   t₂ = t₁ + 1

                                   t₂ = 6 + 1  

                                   t₂ = 7 hours

The total time for the trip is t₁ + t₂ = 6 + 7

                                       = 13 hours

What is m∠AEB? <br> (See attachment)
aleksley [76]
Hey there,
Angle AEB + Angle CED = 180 degrees (vertically opposite angles)
(5x-10) degrees + (3x + 40) degrees = 180 degrees
5x -10 + 3x + 40 = 180 degrees
5x + 3x= 180 + 10 - 40
8x = 150
x = 150 / 8
   = 18.75 degrees 
Angle AEB = (18.75 x 5) - 10 
                  =83.75 degrees.

Hope this helps ^_^
