Please help in Math!? What value of y makes the - 1

Answers

Answer 1
Answer: (-7)/(12) = (y)/(-36)

First, simplify (y)/(-36) to - (y)/(36) / Your problem should look like: - (7)/(12) = -(y)/(36)
Second, multiply both sides by 36. / Your problem should look like: -21=-y
Third, multiply both sides by -1. / Your problem should look like: 21 = y
Fourth, switch your sides. / Your problem should look like: y = 21

Answer: C) 21

What is Pythagoras theorem?

Pythagoras theorem states that “In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides“. The sides of this triangle have been named Perpendicular, Base and Hypotenuse.

Given that, a ladder has a length of 24 ft, and it should be placed at least 8 feet from the base of the side of the house.

We need to find how high can the ladder safely reach,

Using the Pythagoras theorem here,

24²-8² = 576-64 = 512 ft

Hence, the ladder can safely reach up to 22.6 ft.

this is a pythagorean theorem problem. 24 is the whole ladder, and if you draw it out, is a hypotenuse. 8 is a leg. a^(2) + b^(2) = c^(2). so 8^2 + b^2 = 24^2

b^2 = 512, so b = sqrt(512) = 22.6

bruno bought 3 cases of water for a party. guests used 9 bottles of water from each case. write and solve an equation to find how many bottles of water were initially in each case if there were 21 bottles left over

Answers

you would take 9x3 and get  27 and then add that to 21 which is 48 and then divide 48 by 3 and get  16 so 16in each case 
Your answer is 16in per case Hope this help.

If (a,b) is the center and r is the radius of the circle defined by the parametric equationswhat is the value of a+b+r ?
x= 10cos 3t, y= 10sin 3t 0≤t≤ 2pi
This is a bonus problem it is extremely difficult

Answers


Those particular parametric equations generate a circle with its
center at the origin (0, 0).  So ' a ' and ' b ' are both zero.

The (radius of the circle)² is (10² + 10²) = 200

Radius = √200

So (a + b + r) = √200 .  ( about 14.1421 )

The significance of the ' 3t ' in the argument of the 'x' and 'y' is just that as
't' goes from zero to 2π , the parametric equations draw the circle 3 times.

What is 1/6 x 4/5 simplified to

Answers

Answer:2/15

Step-by-step explanation:
First we multiply 1/6* 4/5 by multiply the nominator and the denominator to get one fraction.

So 1*4/5*6= 4/30

Next, we simplify this fraction by dividing by 2 to both 4 and 30

So, after dividing we get: 2/15.

So the answer is 2/15.

I hope this helps!
