Answer:

  • D. -2x + 2y = 1

Step-by-step explanation:

<u>When the line is given in standard form:</u>

  • ax + by = c, it has slope of -a/b

<u>Given line:</u>

  • 4x + 4y = 3

<u>It has a slope:</u>

  • m = -4/4 = -1

A line perpendicular to the given should have a slope m = 1 as negative reciprocal to the given

<u>Let's see which line has the slope of 1:</u>

  • 1. m = -(-1)/6 = 1/6 - NO
  • 2. m = -4/4 = -1 - NO
  • 3. m = -2/4 = -1/2 - NO
  • 4. m = -(-2)/2 = 1 - YES

Correct option is D

Tyler is building a fish tank in the shape of a sphere that has a diameter of 14 inches. Based on Tyler's research, it is recomm
Charra [1.4K]

Answer:

Tyler should buy 2 goldfishes for his fish tank,

Step-by-step explanation:

First let's find the volume of the sphere, using the following equation:

Volume = (4/3) * \pi * radius^3

The radius is half the diameter, so the radius is 14/2 = 7 inches

Now, finding the volume, we have:

Volume = (4/3) * \pi * 7^3

Volume = 1436.75\ in^3

Now, we know that we need to have 1 goldfish for every 693 in3 of water, so to find the number of goldfishes, we just need to divide the volume of the sphere by 693 (and round down the result if needed):

Number\ of\ goldfishes = 1436.75 / 693 = 2.07 = 2\ goldfishes

Tyler should buy 2 goldfishes for his fish tank,

Find the area please
boyakko [2]

Answer:

E 551.625 ft^2

Step-by-step explanation:

We have a rectangle and a circle (2 1/2 circles)

The area of the rectangle is

A = l*w = 15*25 =375

The area of the circle

d =15 so r = d/2 = 7.5

A = pi * r^2

   = 3.14 (7.5)^2

   =176.625

Add the 2 together

375+176.625 =551.625 ft^2
