Sam is flying a kite. The length of the kite string is 80 meters, and it makes an angle of 75° with the ground. The height of the kite from the ground is meters.

Answers

Answer:

THE HEIGHT OF THE KITE FROM THE GROUND=80mtr

Step-by-step explanation:

let H be the height of kite from ground

$\sin\theta$ = $(height)/(hypotenuse)$

$\sin\90$ = $(H)/(80)$

1= $(H)/(80)$

H=80meters

Jerry painted 1/6 of his house on Saturday morning and 3/6 of his house on Sunday morning. How much of his house does he have left to paint.

Answers

$(1)/(6) / (3)/(6) = (1)/(12)$
divide the fractions but the 3 and the six canceled out leaving 3 as 1 and 6 as 2 so multiply that to get 1/12.

A triangle has side lengths of (1.9x + 6.2y) centimeters, (2.5x + 8.3w) centimeters, and (1.6w - 5.1y) centimeters.PART A:

Write an expression that represents the perimeter, in centimeters, of the triangle.

Show all work.

PART B:

Write an equivalent expression to represent the perimeter from PART A. by factoring out the greatest common factor.

Show all work.

IF ANSWER BOTH I WILL GIVE BRAINIEST

Answers

Answer:

Step-by-step explanation:

Part A : Since sides of triangle are ( 1.9x + 6.2y )cm

(2.5x + 8.3w)cm and (1.6w - 5.1y)cm.

Now perimeter of a triangle = sum of all sides length

Perimeter = (1.9x + 6.2y) + (2.5x + 8.3w) + (1.6w - 5.1y)

= (1.9x + 2.5x) + (6.2y - 5.1y) + (8.3w + 1.6w)

[ collecting the like terms together ]

Perimeter = 4.4x + 1.1y + 9.9w

Part B : Now we factorize the term for perimeter given in part A.

Perimeter = 1.1 (4x + y + 9w)

So equivalent factor will be (1.1 (4x + y + 9w).

Answer:

see explanation

Step-by-step explanation:

The perimeter is the sum of the 3 sides, thus summing the 3 sides

1.9x + 6.2y + 2.5x + 8.3w + 1.6w - 5.1y ← combine like terms

= 4.4x + 1.1y + 9.9w ← expression for perimeter

Factor out 1.1 from each term, thus

4.4x + 1.1y + 9.9w

= 1.1(4x + y + 9w) ← perimeter in factored form

{8x [1+(20-6)]}÷ 1/2=

Answers

you would do 20-6 which = 14. + 1 =15. times 8= 120 then divide that by 1/2 = 240 if you do 120 divided by .5 in a calculator thats what you get. i hope that helps you
