Answer:

1 1/2

Step-by-step explanation:

y = 1 1/2x​

The standard equation of direct variation is

y = kx,

where k = constant of proportionality.

Here you have

y = 1 1/2x​,

so 1 1/2 is k, the constant of proportionality.

Answer: 1 1/2

Find the value of each variable.
Harrizon [31]

Step-by-step explanation:

b is per the identity of angles on parallel lines when intersected by one inclined line the same as the 40° angle.

so,

b = 40°

due to the parallel nature of the 2 lines there is a symmetry effect for such shapes inscribed a circle. the upper and the lower triangle must be similar. and when applying a vertical line through the central crossing point, everything to the left is mirrored by everything on the right.

so, angle c must be equal to angle b.

c = 40°

and as the sum of all angles in a triangle is always 180°, d is then

d = 180 - 40 - 40 = 100°

the interior angle of the arc angle a is the supplementary angle of d (together they are 180°), because together with d they cover the full down side of the top-left to bottom-right line.

interior angle to a = 180 - 100 = 80°

due to the symmetry again, the arc angle opposite to a is the same as a.

as we know, the interior angle to a pair of opposing arc angles is the mean value of the 2 angles.

so, we have

(a + a)/2 = 80

2a/2 = 80

a = 80°

there might (and actually should) be some more direct approaches for "a" out of the other pieces of information, but that was the most straight one right out of my mind, and I don't spend time on finding additional shortcuts, when I have already a working approach.

katie bought 4 sweaters that each cost the same amount and 1 skirt that costs 20$. The items she bought cost a total of 160$ bef
Alika [10]
Hello, in order to solve this you first need to take $20 subtracted from 160 that leaves you with 140 next because she bought 4 sweaters you need to divide your remaining cash spent by 4 to get a total of $35 a sweater.

I hope this is what you were looking for, have a great day!

Louis built a swimming pool. The depth of the swimming pool is 5 feet. What is the volume of water that it will take to fill the
julia-pushkina [17]

Answer:

For a rectangular prism-like swimming pool: V = w\cdot l \cdot h. V = 360\,ft^{3} when h = 5\,ft, l = 12\,ft and w = 6\,ft.

Step-by-step explanation:

Let assume that swimming pool has a rectangular base and depth is the same  at any point at the bottom. In addition, let w and l be the width and length of the swimming pool. Then, the volume needed to fill the swimming pool is:

V = w\cdot l \cdot h, where h is the depth of the pool.

Let be h = 5\,ft, l = 12\,ft and w = 6\,ft. The volume of the swimming pool is:

V = (6\,ft)\cdot (12\,ft)\cdot (5\,ft)

V = 360\,ft^{3}

What is the value of x in the equation 2x+7=1
iogann1982 [59]
2x + 7 = 1

Subtract 7 on both sides

2x = 1 - 7

2x = -6

Divide both sides by 2

x = -6/2

x = -3

Your answer is \boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\bf{x=-3}}}}}}}}}}}}}}}}}}}
