A² + b² = c²
90² + 120² = c²
c² = 8100 + 14400
c² = 22500
c = √22500
c = 150

Answer: The diagonal distance is 150m long

barxatty [35]

It should be $92.00

80 • .15 = 12
so 15% of the total ($80) is 12.

add the 12 to the total 80+12= $92

Find the equation of the line that is perpendicular to the line 4x+2y=1 and passes through the point (-4,3)

serious [3.7K]

First find the slope of the given line:

4x +2y = 1

Subtract 4x from each side:

2y = -4x + 1

Divide both sides by 2:

y = -2x +1/2

The slope is -2.

Now use the slope to find the y-intercept. Because the line is perpendicular, you need to use the negative inverse of the slope.

The negative inverse of -2 is 1/2

Now using the point-slope form y - y1 = m(x-x1)

Use the inverse slope for m, and the given point(-4,3) to get:

y - 3 = 1/2(x+4)

Simplify:

y - 3 = x/2 +2

Add 3 to each side:

y = x/2 + 5

Reorder the terms to get y = 1/2x +5

The answer is D.

Tinas rent will increase from $595 this year to $708 next year what is the percent change to the nearest percent

snow_lady [41]

Answer:

The answer rounded to the nearest percent is 19%.

Step-by-step explanation:

The formula for percent change is this:

((y2 - y1) / y1)*100

Let y1 be the first value (595) and let y2 be the second (708).

((702 - 595) / 595)*100

702 - 595 is 107 and 107/595 is approximately 0.188, multiplied by 100 is 18.8, which is rounded to 19%.

That is our solution.

Rachel likes to read books. She records the number of books she read over a period of 5 weeks. The set of ordered pairs below gi

Nataly_w [17]

Answer:

A. both a relation and a function

Step-by-step explanation:

The given set of ordered pairs is

{(1,2),(2,3),(3,1),(4,4),(5,2)}.

This ordered pairs represent a relation.

The x-coordinates represent the domain and the co-domain or range is the set of the y-coordinates.

The relation is many-to-one relation.

All many-to-one relations are functions.

The correct choice is A.
