Answer from: kyle65

1. distribute

step 1: 3 3

× X = X

5 5

3 5 3 Ima convert this into a decimal

× - = - > negative .375

5 8 8

2. write the problem now

3 1 7

X - 0.375 = - X +

5 12 8

3. I would convert them into decimals and solve

0.6x - 0.375 = 0.08 - x + 0.875

+x +x

1.6x - 0.375 = 0.08 + 0.876

1.6x - 0.375 = 0.956

+0.375 +0.375

1.6x = 1.331

1.6 1.6

x = 0.831875

rounded up : 0.83

Answer from: jason8093

Combine like terms
1/12+7/8=2/24+21/24=23/24
3/5(x-5/8)=23/24-x
one easey way is to get rid of nasty fractions

find lcd of denoms
5 and 24
hmm
24*5=120

times both sides by 120

72(x-5/8)=115-120x
distribute
72x-45=115-120x
add 120x to both sides
192x-45=115
add 45 to both sides
192x=160
divide both sides by 192
x=5/6

x=5/6

For the first question the answer is a, for the second c, for the third d, for the 4th b, for the 5th a

Answer from: Quest

answer: hence, function will be

$y=85(\frac{3}{4})^x$

explanation:

since we have given that

cost of a new textbook = $85

according to question, the resale value of a textbook decreases by 25% with each previous owner,

so, our function becomes,

$y=85(1-\frac{25}{100})^x\\\\y=85(\frac{100-25}{100})^x\\\\y=85(\frac{75}{100})^x\\\\y=85(\frac{3}{4})^x$

here, y is the total value of the text book after x owners.

hence, function will be

$y=85(\frac{3}{4})^x$

I've been working on this for a few days and i just don't understand, it's due in a few hours. you. the direction of a vector is defined as the angle of the vector in relation to a horizontal line. as a standard, this angle is measured counterclockwise from the positive x-axis. the direction or angle of v in the diagram is α. part a: how can you use trigonometric ratios to calculate the direction α of a general vector v = < x, y> similar to the diagram? part b suppose that vector v lies in quadrant ii, quadrant iii, or quadrant iv. how can you use trigonometric ratios to calculate the direction (i.e., angle) of the vector in each of these quadrants with respect to the positive x-axis? the angle between the vector and the positive x-axis will be greater than 90 degrees in each case. part c now try a numerical problem. what is the direction of the vector w = < -1, 6 > ?
