A right triangle has an opposite of 6 meters and an adjacent of 8 meters. Find the angle measures (answer)

SOHCAHTOA You are given the opposite and the adjacent so you would use tangent. Tan = Opp / Adj = 6/8 = .75 So the angle is the inverse tangent of .75 or tan-1(.75) = 36.9 All angles in any triangle add up to 180 degrees, of which...

How do you factor, ab + 3b + 2a + 6? (answer)

You factor by grouping. (ab + 3b) + (2a +6) Then you take out like terms, you need to make sure the terms left in the () are the same. b(a + 3) + 2(a + 3) This can now be written as: (b + 2)(a...

You need a couple things to answer this question. First you need the formula for gallons to liters conversion. This is L = G / 0.26417 So 1G is equivalent to 3.7854L Now you multiply that by the cost per L in Euros: 1.35(3...

No, you are multiplying two binomials. It would be (x+5)(x+5) and you would have to FOIL it, First Outer Inner Last or: x2 + 5x + 5x + 25 = x2 + 10x + 25 This is actually making it more complex not less.

Let VP = Present Value (x) Let VI = Initial Value (11,000) Let r = Rate (.10) Let I = VI + rVI Then VP = I + rI Let's get I first: 11,000 + .10(11,000) = 11,000 + 1,100 I...

Absolute Value Reasoning (answer)

The definition of a function is that every x value may have one and only one corresponding y value. Graphically we can test this by something called the VLT or vertical line test. If an equation is a function you must be able to draw a vertical line through it at any x value within...

There is not enough information here to solve this. I'm guessing you have a figure to go off of with some known values. Formula of a parallelogram's perimeter is P = 2L + 2W

P = 2L + 2W Substituting known W + 14.4 = 2(2W - 0.3) + 2W -W ...

urgent, please answer (answer)

You need to remember one thing with inequalities. When you multiply or divide by a negative number you need to flip the inequality sign. Otherwise you solve it just as if it were a normal equation. So number 4 for instance: x/-10 > 6 * -10 ...

jekyll scale water freezes at 17 and boils at 97; Hyde scale water freezes at 0 and boils at 120 (answer)

They have different start points 17J vs 0H so you need to add/subtract 17 They raise at different rates 80 vs 120 so you will need to multiply J = (H * 2/3) + 17 H = (J - 17)(3/2) The fractions were achieved by reducing the...

Ok, first set the equations equal to each other. 500t3/2 = 100t2 Then isolate the t terms. 500t3/2 / 100 = t2 5t3/2 = t2 t2 / t3/2 = 5 Now remember that division of exponents with same base are subtracted...
