Answer:

32:3

Step-by-step explanation:

64:(48-42)

Note that 64:(48-42)

Can also be written as 64/(48-42)

So let's solve (48-42) first

So 64/(48-42)=64/6

64/6

Divide both by 2

32/3

So let's convert back to ratio

32:3

Therefore the final answer is 32:3

Step-by-step explanation:

point (x,y) that divides the segment PI in the ratio 2 to 1

PD=4 - (-2) = 6 PE/ED=2/1 PE=2ED PE+ED=6 3ED=6 ED=2 PE=4

coordinate of E (2,1) .... 2 is x coordinate of E

A line that has a rise of -34 and a run of 20.

aleksandr82 [10.1K]

Answer:

$y=-1.7x-34$

Step-by-step explanation:

An equation of a line is given $y=mx+c$ , where m is the gradient or $\frac{Rise}{Run}$

The rise indicates the change in value of y (vertical change in the graph).

The run indicates the change in value of x (horizontal change in the graph).

Let point 1 of the graph be (x,y) = (0,-34) and point 2 be (x,y) = (20,0).

$m =\frac{Rise}{Run} \\ =\frac{-34}{20}\\ =-1.7$

Substitute point 1 into the graph to get the constant c.

$y=mx+c$

$-34=(-1.7)*(0)+c$

$c=-34$

∴ The equation of the line is, $y=-1.7x-34$

A garden has the form of a right triangle. One leg of the triangle is formed by a 2400-ft long sea wall. The hypotenuse of the

stepladder [879]

Answer:

given leg: 2400 ft
other leg: 1000 ft
hypotenuse: 2600 ft

Step-by-step explanation:

The Pythagorean theorem tells a relation between the leg lengths and the hypotenuse. If x represents the unknown leg length, then we have ...

x^2 + 2400^2 = (x +1600)^2

x^2 +5760000 = x^2 +3200x +2560000 . . . . eliminate parentheses

3200000 = 3200x . . . . . . . . . subtract x^2+2560000

1000 = x . . . . . . . . . . . . . . divide by 3200

The other leg length of the garden is 1000 ft. The garden is a triangle with side lengths 1000 ft, 2400 ft, 2600 ft.
