Byron can fill a drying rack with dishes in 15 minutes. While Byron fills the drying rack, Emmitt takes dishes out of the drying
Olegator [25]

Answer:

Hi!

The correct answer is d) 1 over 15 minus 1 over x equals x over 35.

Step-by-step explanation:

We know the amount of time that Byron can fill a drying rack with dishes: 15 minutes.

We know the amount of time that Byron can fill a drying rack with dishes while Emmitt is taking dishes out of the drying rack: 35 minutes.

We don't know the amount of time that Emmitt can take dishes out of the drying rack: x minutes.

So, if Byron is filling the drying rack in 15 minutes and Emmitt is taking out the dishes at x minutes, it takes 35 minutes to fill the drying rack.

\frac{1}{15}-\frac{1}{x} = \frac{1}{35} <em>// multiply by 105x both sides.</em>

105x\frac{1}{15}-105x\frac{1}{x} =105x \frac{1}{35} <em>// simplifly</em>

7x - 105 = 3x<em> //substract 3x and add 105 in both sides</em>

7x - 3x - 105 + 105 = 3x - 3x + 105 <em>// solve</em>

4x =  105 <em>//</em> <em>divide by 4 in both sides</em>

\frac{4x}{4} =  \frac{105}{4} <em>// solve</em>

x =  26.25

It makes sense that Byron fills the rack faster than Emmitt empties the rack.

What is the relationship between the coordinates of the vertices for ABC and the corresponding vertices for A'B'C'? Explain the
Nina [5.8K]

The ratio of each vertex coordinate on ΔA'B'C to the corresponding vertex coordinate on ΔABC is equal to 2. For example, A(1, 1) → A′(2, 2). This ratio is equal to the scale factor, n.

What is an equation of the line
Firdavs [7]

Answer:

Step-by-step explanation:

A line that is perpendicular to a reference line will have a slope that is the negative inverse of the reference line.

In this case, the reference line is y = -x - 1.  It has a slope of -1.  The negative inverse of this would be -(1/-1) = 1.

We can then write:

y = mx + b

y = 1x + b

To find b, enter the one given point that lines on the line, (-4,2).

y = 1x + b

y = 1x + b for (-4,2)

2 = 1(-4) + b

b = 6

The equation becomes y = x + 6

See attached.

Umm anyone know this..
RUDIKE [14]

Answer:

Sine is equal to opposite over hypotenuse in right triangles. Let's say we have a 3-4-5 right triangle, the side opposite the 90° angle is 5, and 5 is also the hypotenuse. 5/5 = 1

Therefore, in all right triangles, the side opposite the 90° angle is equal to the hypotenuse, and anything over itself is equal to one.

(Not sure if this is a mathematically correct way to explain it, but it makes the most sense to me.)
