Answer:

C. The equation should x/17=118.82

Step-by-step explanation:

We know that

Dividend ÷ Divisor = Quotient

Dividend/Divisor = Quotient

From the question, we are told that:

The quotient of a number and 17 is 118.82

Let us represent the unknown number as x = Dividend

17 = Divisor

Quotient = 118.82

Hence,

x / 17 = 118.82

Cross Multiply

x = 17 × 118.82

x = 2019.94

The correct answer = Option C. The equation should x/17=118.82

X= r-h/y<br> solve for h and r

malfutka [58]

X = r - h/y ; Solve for h & r

Let's first solve for h :)

Add h/y to both sides.

h/y + x = r

So, r = h/y + x

Now, let's solve for h.

x = r-h/y

Subtract r from both sides.

-r + x = -h/y

Multiply both sides by y.

y(-r + x) = y(-h/y)

Simplify.

-ry + xy = -h

Divide both sides by -1.

ry - xy = h

So, h = ry - xy

Tri City sells four times as many dishwashers as Solly Company. The difference between their sales is 96 dishwashers. How many d

kondaur [170]

We use a system of equations to solve this. Since tri city sells 4 times it becomes 4x and solly company is x. Then we do 4x-x=96. 3x=96. x=32. We are not finished yet. We still have to multiply x by 4. x=128. Tri City sold 128 dishwashers.

A ball is shot straight up from the top of a 15-story building. The motion of the ball could be described by the function: h(t)=

viktelen [127]

Answer:

After 4 seconds the height is 480 meters.
The maximum height is 484 meters.
The ball hits the ground after 10 seconds

Step-by-step explanation:

The height after four seconds is h(4) = -16 * r² + 144*4+160 = 480

The maximum height of the ball is the value it takes at its vertex 'v = -b/2a'. In this case a = -16 and b = 144, so the v = -144/-32 = 4.5. The maximum height of the ball as a result is h(4.5) = -16 (4.5)² + 144*4.5 + 160 = 484

To find the moment the ball hits the ground, we need to find when h takes the value 0 by using the quadratic formula, with a = -16, b = 144 and c = 160.

$r_1,r_2 = \frac{-144 \, ^+_- \sqrt{144^2-4*(-16)*160}}{2*(-16)} = \frac{-144 \, ^+_- \sqrt{30976}}{-32} = \frac{-144 \, ^+_- 176}{-32} = -1, 10$

Since t cant take negative values, then the correct value is 10. The ball hits the ground after 10 seconds.
