Answer:

Shirts:  $8

Pants:  $13

Step-by-step explanation:

2 shirts and 2 pairs of pants costs $42.

2x + 2y = 42

3 shirts and 1 pair of pants costs $37.

3x + y = 37

Use substitution to solve.  Rearrange the second equation so that it is equal to y.  Plug in the value for y into the first equation.

3x + y = 37

y = 37 - 3x

2x + 2y = 42

2x + 2(37 - 3x) = 42

2x + 74 - 6x = 42

74 - 4x = 42

-4x = -32

x = 8

Now that you have the value for x, solve for y using one of the equations.  I will use the first equation, but you can use the other one and still get the right answer.

2x + 2y = 42

2(8) + 2y = 42

16 + 2y = 42

2y = 26

y = 13

The shirts cost $8, and the pants cost $13.

An athlete trains on a circular track of radius 40 m and jogs 10 laps each day, 5 days a week. How far does he jog each week? Ro
mariarad [96]
Length of a circle=2πr
r=40 m
Length of the circular track=2*π*40m=80π m.

The athelete jogs each day 10 laps
1 lap-------------------80π m
10 laps-------------   x
x=(10 laps * 80π m) / 1 lap=800π m

Calculate how far he jog eache week (5 days).
1 day------------------800π m
5 days----------------   x
x=(5 days*800π m)/1day=4000π m=4000m * 3.141592...≈12566,37 m

solution: 12566 m

Cos (-Ø)= √3/3 sinØ <0 what is the value of sinØ?
Inga [223]

Answer:

sin∅= - √6/3

Step-by-step explanation:

Trigonometric function cos is even function which mean:

cos (-∅) = cos ∅

Trigonometric function sin is odd function which mean:

sin (-∅) = - sin∅  => sin∅ < 0

The basic trigonometric equation reads in this case with angle marked ∅:

sin²∅ + cos²∅ = 1  => sin²∅ = 1 - cos²∅ => sin²∅ = 1 - ( √3/3 )² =>

sin²∅ = 1 - (3/9) => sin²∅ = 1 - (1/3) = (3/3) - (1/3) = 2/3 => sin∅ = - √(2/3) =>

sin∅ = - √2/√3 => sin∅ = - √6/3

God with you!!!
