Answer:

Tablet: 300

Laptop: 100

Step-by-step explanation:

You can simplify the ratio from 6:2 to 3:1. If you multiply 1 and 3 by 100, you get 300 tablets and 100 laptops, which supports the information in the question (200 more tablets).

5. Use the equation shown to answer a-b.
soldi70 [24.7K]

Answer:

a. No

b. 2.25 days

Step-by-step explanation:

0.75x + 3 = 0.25x + 5.25

a......................

Constants are $3 and $5.25 respectively

Topping costs $0.75 and $0.25 respectively

To have same cost the toppings number would be different as cost is different.

Suppose the number of toppings is x in one shop and y in the other, then the spending if same, we get this equation:

  • 0.75x + 3 = 0.25y + 5.25

The answer is NO due to two different variables in the equation

b.......................

Constants are $3 and $5.25 respectively

Joseph adds $0.75 each day and Kelsey spends $0.25 each day

Number of days should be same in this case, so variable will be same and the result (amount left in bank) is same.

<u>So the equation for this case is:</u>

  • 3 + 0.75x = 5.25 - 025x

<u>Solving, we get:</u>

  • 0.75x + 0.25x = 5.25 - 3
  • x = 2.25

This is the solution to equation despite being a whole number.

URGENT HELP ASAP, PLEASE HELP WITH MY GRADE 11 MATH!
cluponka [151]

Half-Life Formula:

Amount remaining = (Initial amount)[ (1/2)^(time / half-life) ]

Amount remaining = ?

Initial amount = 200 mg

Time = 2 hours = 120 minutes

Half-Life = 20 mins

---Notice that I changed the time from hours to minutes. The time and half-life time need to be in the same unit.

A = (200)[ (1/2)^(120/20) ]

A = (200)(1/2 ^6)

A = (200)(1/64)

A = 3.125

Answer: 3.125 mg remain

Hope this helps!

Answer:

Step-by-step explanation:

Change g(n) to y

y = 2n - 2

2y - 2 = n

2y = n + 2

y = (n + 2)/2

g^-1(n) = 1/2n + 1

solution is B

A 45 foot ladder is leaning against a building. If the bottom of the ladder is 27 feet from the base of the building, how tall i
taurus [48]

Answer:

The height of building to the nearest foot is h = 36 foot

Step-by-step explanation:

We have given,

Length of ladder leaning against a building, l = 45 foot

Bottom length between ladder and the building , b = 27

Now, we need to find the height of building to the nearest foot.

Let the height of building be h.

Using Pythagoras theorem,

l^{2} = b^{2} +h^{2}

Here, l = 45 , b = 27 and h =?

So,

45^{2} = 27^{2} +h^{2}

h² = 45² - 27²

h = √(45² - 27²)

h = 36

The height of building to the nearest foot is h = 36 foot

In a village the number of houses and the number of flats are in the ratio 9:5 the number of flats and the number of bungalows T
Makovka662 [10]

Answer:

Total no. of houses = 140

Step-by-step explanation:

Let there are 9x flats and 5x bungalows.

Total bungalows = 50

It means,

5x = 50

x = 10

No of flats = 9x

= 9(10)

= 90

Total houses = no. of flats + no. of bungalows

= 50+90

= 140

So, there are 140 houses in the village.
