Hi there!

Let's solve this inequality step by step!
$- 6r + 2r > 3 - 3r$

First collect the terms on the left.
$- 4r > 3 - 3r$

In order to solve, we must isolate r. Therefore we need to bring them all to the left. Our next step will therefore be to add 3r to both sides of the equation.
$- r > 3$

Finally we need to divide both sides of the equation by -1. Because we divide by a negative, the sign flips.
$r < - 3$

Hence, the answer is r < -3.
~ Hope this helps you!

The perimeter of a rectangle is 28.8 centimeters. The length of the rectangle is twice as long as it’s with. Find the length and

Mazyrski [523]

Answer:

$Length=9.6 cm\\\\Width=4.8 cm$

Step-by-step explanation:

Length=2*Width

L=2*W

Perimeter=28.8 cm

Perimeter of a rectangle= 2(Length+Width)

$28.8=2(2W+W)\\\\28.8=2(3W)\\\\3W=28.8/2\\\\3W=14.4\\\\W=14.4/3\\\\W=4.8 cm\\\\$

$Length=2*Width\\\\=2*4.8\\\\=9.6 cm\\\\$

$Length=9.6 cm\\\\Width=4.8 cm$

A trough is 10 ft long and its ends have the shape of isosceles triangles that are 4 ft across at the top and have a height of 1

Anna11 [10]

Answer:

7.5 ft³/min

Step-by-step explanation:

Let x be the depth below the surface of the water. The height, h of the water is thus h = 10 - x.

Now, the volume of water V = Ah where A = area of isosceles base of trough = 1/2bh' where b = base of triangle = 4 ft and h' = height of triangle = 1 ft. So, A = 1/2 × 4 ft × 1 ft = 2 ft²

So, V = Ah = 2h = 2(10 - x)

The rate of change of volume is thus

dV/dt = d[2(10 - x)]/dt = -2dx/dt

Since dV/dt = 15 ft³/min,

dx/dt = -(dV/dt)/2 = -15 ft³/min ÷ 2 = -7.5 ft³/min

Since the height of the water is h = 10 - x, the rate at which the water level is rising is dh/dt = d[10 - x]/dt

= -dx/dt

= -(-7.5 ft³/min)

= 7.5 ft³/min

And the height at this point when x = 8 inches = 8 in × 1 ft/12 in = 0.67 ft is h = (10 - 0.67) ft = 9.33 ft

Paula, the local baker, usually makes 15 loaves of bread and 10 cakes per day, but today she made 25 loaves of bread and 12 cake

frozen [14]

Answer:

Step-by-step explanation:

The percent increase formula is

$%increase=\frac{new-original}{original}*100%$

For the bread, our percent increase looks like this:

$\frac{25-15}{15}*100$

which gives us a percent increase of 66.7%

For the cakes, our percent increase looks like this:

$\frac{12-10}{10}*100$

which gives us a percent increase of 20%
