d =

Answers

Answer:

d = 9/10

Step-by-step explanation:

Hi,

d divided by 5/6 = 3/4

You can't divide fractions, instead, you flip the fraction and multiply. So, in this case, you would flip 5/6 to get 6/5 and multiply it by 3/4 to get d.

d ÷ 5/6 = 3/4

Multiply both sides by 6/5 (remember to flip)

d = 3/4 x 6/5

(when multiplying fractions, you can multiply straight across)

d = 18/20

(simplify - both numbers can be divided by 2)

d = 9/10

Hope this helps :)

Answer:

d = 5/8

Step-by-step explanation:

Mulitply by the reciprocal

= d x 6/5 = 3/4

Reorder the terms

=6/5d = 3/4

Multiply both sides

Solution

d = 5/8

Alternate form

d = 0.625

Answer:

Step-by-step Yes it is, assuming we decide to use the Pythagorean Theorem to find the hypotenuse (10) it'll be possible considering the formula is c²=√a²+b²

(c being the longest side of the triangle)

a= 6 and b= 8

c² =√6² + 8²

A boy is flying a kite. The string of the kite has a 40° angle of elevation parallel to the ground. The kite is 30 meters above the ground, and the boy’s hand is 1.5 meters in the air. Find the length of the kite string. Round your answer to the nearest meter.

Answers

Answer:

Step-by-step explanation:

we want to find the Hypotenuse of the triangle being made by the string , the ground and the height off the ground. Also we will have to subtract the small triangle of the boy's hand from the ground

the big triangle Hyp is found by using

SOH or Sin = Opp / Hyp

we know the sin and the Opposite soooo

Sin(40) = 30 / Hyp

Hyp = 30 / Sin(40) [ I'll use my calculator for this ]

Hyp = 46.67 m ( this is the Hypotenuse of the big triangle )

the small one is

Sin(40) = 1.5 / Hyp

Hyp = 1.5 / Sin(40) [calculator again ]

Hyp = 0.9641 m

Now subtract the small one from the big one

46.67 - 0.9641 = 45.7 m

rounding to the nearest meter the answer is 46 m

Please can someone help me !!!!

Answers

Answer:

x = 7y - 16

Step-by-step explanation:

First, isolate x by adding 14y to both sides:

2x - 14y = -32

2x = 14y - 32

Now, divide each side by 2:

x = 7y - 16

So, x = 7y - 16

Answer:

x=-16+7y

Step-by-step explanation:

2x-14y=-32move the varIables to the right and change its sign2x=-32+14ydivide both sides of the equation by 2x=-16+7y
