Bryn's age is given by the expression 3g - 7, where g is her sister Gabriela's age. If Bryn is 17, how old is Gabriela?

1 answer:

8 0

You are told that B=3g-7 and you are also told that B=17 so

3g-7=17 add 7 to both sides

3g=24 divide both sides by 3

g=8

So Gabriela is 8 years of age.

Answer :-

9(3+√3) feet

Step by step explanation :-

A triangle is given to us. In which one angle is 30° and length of one side is 18ft ( hypontenuse) .So here we can use trignometric Ratios to find values of rest sides. Let's lable the figure as ∆ABC .

Now here the other angle will be = (90°-30°)=60° .

In ∆ABC ,

=> sin 30 ° = AB / AC

=> 1/2 = AB / 18ft

=> AB = 18ft/2

=> AB = 9ft .

Again In ∆ ABC ,

=> cos 30° = BC / AC

=> √3/2 = BC / 18ft

=> BC = 18 * √3/2 ft

=> BC = 9√3 ft .

Hence the perimeter will be equal to the sum of all sides = ( 18 + 9 + 9√3 ) ft = 27 + 9√3 ft = 9(3+√3) ft .

<h3>Hence the perimeter of the triangular pathway shown is 9 ( 3 + √3 ) ft .</h3>

Answer:

Yes, you can buy the used car with $849.92 left over.

Step-by-step explanation:

20 hours per week for 52 weeks = 1040 hours

1040 hours at $8 = $8320 per year

FICA = 8320 x 0.0565 = $470.08

8320 - 470.08 = $7849.92
