Perform the modular arithmetic. (7 · 15) (mod 4)
Reika [66]

We could do it by first writing

7\cdot15=(4+3)\cdot(4+11)=4^2+14\cdot4+33

so that

7\cdot15\equiv4^2+14\cdot4+33\equiv33\pmod4

and since 33=32+1=8\cdot4+1, we have

7\cdot15\equiv33\equiv1\pmod4

# # #

Alternatively, we can just compute the product and take it mod 4:

7\cdot15=105=104+1=26\cdot4+1

and so we get the same result of 1.

brian invests £4700 into his bank account he recieves 5.5% compound intrest how much will brian have after 3 years?
alexandr1967 [171]

Answer:

Brian will have £817.8

Step-by-step explanation:

Principal = £4700

interest = 5.5% = 0.055

n = 3 years

Amount = [(Principal * (1 + interest)ⁿ) - Principal]

Amount = [(4,700 * (1 + 0.055)³) - 4,700]

Amount = [(4,700 * (1.055)³) - 4,700]

Amount = [(4,700 * 1.174) - 4,700]

Amount = [5,517.8 - 4,700]

Amount = £817.8

Find the width (w) of the rectangle if the area of the rectangle is x2 + 18x + 45.
poizon [28]

I'm not sure if you're already given the length of the rectangle, but the width is either (x + 3) or (x + 15).

We can find this by factoring x² + 18x + 45, as the area of a rectangle is found by multiplying the length and width together, so if we factor this expression we can find what was multiplied together.

Factoring x² + 18x + 45, we get (x + 3)(x + 15), which then tells us the two sides of the rectangle. Again, I'm not sure if you were already told the length, but if you were then the width is the other side. For example, if you were told the length was (x + 3), then the width would be (x + 15).

I hope this helps!

You can upgrade lighting at your factory to LED bulbs that coast 6.95 each and last an average of 5 years.
miskamm [114]

Answer:

$200

Step-by-step explanation:

Here is the full question

You can upgrade lighting at your factory to LED bulbs that cost $6.95 each and last an average of 5 years. It costs $3 in labor to change a bulb. Over a 10-year period, about how much will it cost per year to install LED bulbs in 100 lamps and change the bulbs when they burn out?

in 10 years, the bulbs would be changed twice

Total cost incurred per bulb in 10 years = (6.95 +  $3) x 2 = $19.90

Since there are 100 bulbs, total cost incurred would be - $19.90 x 100 = $1990

Cost per year = $1990 /  (6.95 +  $3) = $200
