Given quadrilateral RSTU, determine if each pair of sides (if any) are parallel and which are perpendicular for the coordinates

Mrac [35]

Slope RS: 2/3
Slope ST: -3/2
Slope TU: 4/6 = 2/3
Slope UR: -1/5

Sides RS and TU have the same slope, so they are parallel.
The slope of side ST is the negative reciprocal of the slopes of sides RS and TU, so side ST is perpendicular to sides RS and TU.
Side UR is not parallel or perpendicular to any other side.

The quadrilateral is a trapezoid.

Find the area of a triangle with a base of 7.5 m and a height of 4*

oksian1 [2.3K]

Answer:

15 units²

Step-by-step explanation:

Hi there!

$A=\displaystyle\frac{1}{2} bh$ where <em>b</em> is the base and <em>h</em> is the height

Plug in the base (7.5) and height (4):

$A=\displaystyle\frac{1}{2} (7.5)(4)\\\\A=\displaystyle\frac{1}{2} (30)\\\\A=15$

Therefore, the area of the triangle is 15 units².

I hope this helps!

Natalie earned $200 in interest and 30 months with a beginning balance of $1040. What was her interest rate?

rjkz [21]

The interest rate is 7.69%

Step-by-step explanation:

Given

Interest = $200

Time = t = 30 months

Time will be converted into years as the rate is applied yearly

So,

1 year = 12 months

30 months = 30/12 years = 2.5 years

Principal amount = $1040

The formula for interest is:

$I = P*r*t$

Putting the values

$200 = 1040 * r * 2.5\\200 = 2600r\\r = \frac{200}{2600}\\r = 0.076923$

Converting into percentage:

r = 7.6923

Rounding off to nearest hundredth

r = 7.69%

Hence,

The interest rate is 7.69%
