_________________________ 6​Harry is planning a holiday for 4 people for 7 days. Here are the costs for the holiday for each person. Travel​£150 Hotel​£50 for each day Spending money​£250 Work out the total cost of the holiday for 4 people for 7 days.

Answers

Answer: $3,000

Step-by-step explanation:

The cost for a single person is:

Travel      £150

Hotel       £50 for each day

Spending money       £250

Hotel is the only one that changes per the number of days so the total cost for a single person for 7 days is:

= 150 + (50 * 7) + 250

= 150 + 350 + 250

= $750

There are 4 people so the total cost will be:

= 750 * 4 people

= $3,000

what is the base if the height is 6ft and the area is 14 ft on a triangle ​

Answers

Answer:

b = 4.66666667

Step-by-step explanation:

The equation for finding the area of a triangle is

0.5b x h = a

b = base

h = height

a = area

So I calculated 14 divided by 6

And got 2.3333333

And since that number is half of the base, I multiplied it by 2

2.333 x 2 ≈ 4.66666667

A pipe leaks water at a rate of 48 fl oz
every 5 min.
At this rate, how many gallons of water leak from the pipe in an hour? (1
gal = 128 fl oz)

Answers

12*5=60
12*48=576
576/128=4.5
4.5 gallons

The number of gallons of water leaking from the pipe in an hour will be 4.5 gallons per hour.

What is conversion?

Unit modification is the process of converting the measurement of a given amount between various units, often by multiplicative constants that alter the value of the calculated quantity without altering its impacts.

A pipe leaks water at a rate of 48 fl oz every 5 min. Then the rate is given as,

Rate = 48 / 5 fl oz per minute

We know that 1 gal = 128 fl oz, then we have

Rate = (48 / 128) / (5 / 60)

Rate = (48 x 60) / (128 x 5)

Rate = 2880 / 640

Rate = 4.5 gallons per hour

The number of gallons of water leaking from the pipe in an hour will be 4.5 gallons per hour.

The 3 triangles are all similar.

Using the 2 inside then the ratios of corresponding sides are equal, that is

[tex]\frac{x}{3}[/tex] = [tex]\frac{12}{x}[/tex] ( cross- multiply )

x² = 36 ( take the square root of both sides )

x = [tex]\sqrt{36}[/tex] = 6 → C

Answer:

C) x = 6

because this is a right triangle

=> we have:

(12² + x²)(3² + x²) = (15x)²

<=> 1296 + 153x² + x⁴ = 225x²

<=> x⁴ - 72x² + 1296 = 0

<=> (x² - 36)² = 0

<=> x² = 36

=> x = 6
