2 =  5x = 5 x 356 = 1780

Step-by-step explanation:

Rupees = 2848

3x + 5x = 2848

8x = 2848

x = 2848 / 8 = 356

1 = 3x = 3 x 356 = 1068

2 =  5x = 5 x 356 = 1780

Answer:

Step-by-step explanation:

[tex]3h+\sqrt{2}=\sqrt{5}\\ \\ 3h=\sqrt{5}-\sqrt{2}\\ \\ h=\frac{\sqrt{5}-\sqrt{2}}{3}[/tex]

Question:

3h+sqrt.2=sqrt.5

Answer:

h=sqrt.5-sqrt.2/3 (the very last option)

Method:

You have to get h on its own so you start by subtracting sqrt.2 on both sides, you subtract because you have to reverse the original symbol (+ becomes -, ^2 becomes sqrt., * becomes /, and the other way around, etc.), once you do that you have to divide by 3 on both sides and you get your answer.

Visual:

1. 3h+sqrt.2=sqrt.5
-sqrt.2 -sqrt.2

2. 3h=sqrt.5-sqrt.2
/3 /3

3. h=sqrt.5-sqrt.2 /3

Each time Caroline goes shopping she decides whether or not to buy fruit.
The probability that she does buy fruit is 0.4.
Independently, she then decides whether or not to buy a CD, with a probability of 0.3 that she does buy a CD.
Work out the probability that she buys fruit or buys a CD or both.

Answers

Answer:  0.58

Step-by-step explanation:

Step 1 : Caroline buys fruit and buys cd ( buys both) = 0.12      ( 0.4 x 0.3)

Step 2 : Caroline buys fruit and not cd =  0.28                          ( 0.4 x 0.7)

Step 3 : Caroline doesn't buy fruit but buys cd = 0.18               ( 0.6 x 0.3 )

STEP 4 (FINAL STEP) : Add all the probabilities ( 0.12 + 0.28 + 0.18)

A teacher lives 8 miles from school. She drives a 2015 Chevy Camaro that gets 19 miles per gallon of gas. How much fuel will she need to get TO AND FROM work for the week?

Answers

Answer:

Step-by-step explanation:

Technically we cannot solve this without knowing how many days a week that she works.

f=(16mi*d)(gal/19mi)

f=(16/19)d

We would have to assume that she works a certain amount of days. If we assume she works every day

f=7(16/19)=112/19, approximately 5.9 gal

A rectangular garden has a walkway around it. The area of the garden is 6(5.5x + 2.5). The
combined area of the garden and the walkway is 7.5(8x +4). Find the area of the walkway around
the garden as the sum of two terms.​

Answers

Answer:The area of the walkway around is 26 x + 16 as the sum of two terms

Step-by-step explanation:

A rectangular garden has a walkway around it

1. The area of the garden is 4(4.5 x + 1.5)

2. The combined area of the garden and the walkway is 5.5(8 x + 4)

We need to find the area of the the walkway

To find the area of the walkway by subtracting the area of the

rectangle from the combined area

∵ The combined area = 5.5(8 x + 4) ⇒ simplify it

∴ The combined area = 5.5(8 x) + 5.5(4)

∴ The combined area = 44 x + 22

∵ The area of the garden = 4(4.5 x + 1.5) ⇒ simplify it

∴ The area of the garden = 4(4.5 x) + 4(1.5)

∴ The area of the garden = 18 x + 6

Now subtract the area of the garden from the combined area

∵ Area of the walkway = (44 x + 22) - (18 x + 6)

∴ Area of the walkway = 44x + 22 - 18 x - 6

- Add like terms

∴ Area of the walkway = (44 x - 18 x) + (22 - 6)

∴ Area of the walkway = 26 x + 16

The area of the walkway around is 26 x + 16 as the sum of two terms
