On a trip, you had to change your money from dollars to British pounds. You got 560 pounds for 800 dollars. How many pounds will

VladimirAG [237]

Use proportions to solve this. Set up the ratios with dollars on the top and pounds on the bottom and then cross-multiply to solve for x. Like this: $\frac{d}{p}: \frac{800}{560}= \frac{300}{x}$ . Cross multiplying gives us 800x=168,000. Divide by 800 to get that x = 210. So $300 equals 210 pounds.

Find the area of a figure

motikmotik

Answer:

4.62 sq ft

Step-by-step explanation:

Area of rectangle = 2.5 x 1 = 2.5

To get area of triangle we must use the altitude theorem to find the height:

let 'x' = altitude (or height)

x/1.5 = 2/x

cross-multiply to get:

x² = 3

x = $\sqrt{3}$

Area of triangle = 1/2(2.5)( $\sqrt{3}$ )

= 1.25 $\sqrt{3}$ which is approx 2.12

Total area = 2.5 + 2.12 = 4.62

Which number produces an irrational number when added to 0.4

erastovalidia [21]

Answer:

0.31311311131111....

Step-by-step explanation:

We need to tell a number which when adds to 0.4 makes it a Irrational Number . We know that ,

Rational number :- The number in the form of p/q where p and q are integers and q is not equal to zero is called a Rational number .

Irrational number :- Non terminating and non repeating decimals are called irrational number .

Recall the property that :-

Property :- Sum of a Rational Number and a Irrational number is Irrational .

So basically here we can add any Irrational number to 0.4 to make it Irrational . One Irrational number is ,

$\rm\implies Irrational\ Number = 0.31311311131111...$

So when we add this to 0.4 , the result will be Irrational . That is ,

$\rm\implies 0.4 + 0.31311311131111 ... = 0.731311311131111 ..$

What is the slope of the line that contains the points (-1, 2) and (3, 3)?

iren [92.7K]

Answer:

1/4

Step-by-step explanation:

Slope of a line can be found if given two points by using the formula $\frac{y_2-y_1}{x_2-x_1}$ where $(x_1,y_1) \text{ and } (x_2,y_2)$ are points on the line.

However, I like to line up the points vertically and subtract then put 2nd difference over 1st difference.

Like this:

( 3 , 3 )

-( -1 , 2 )

---------------------

4 1

So the slope is 1/4.
