Answer:

Question 1) 6x+5

Question 2) Blank #1: sum. Blank #2: 5. Blank #3: 4

See work in the attachment. If you're still confused, read the step-by-step explanation for a more in-depth explanation of what exactly I did for my work. Let me know if you have any questions :>

Step-by-step explanation:

For question 1, it's important to know that the perimeter is equal to the sum of all the sides. Since the shape is a rectangle, the sides opposite of each other are the same length. Thus, the left and right sides are both 3x - 3. 2(3x - 3) = 6x - 6. The unknown value, which I called a, is the same for both the top and the bottom. To find it, you must first subtract 6x - 6 from the perimeter of 18x + 4. This equals 12x + 10. Then, divide that answer by 2 to get the unknown side. You then get 6x + 5 as the answer for the unknown side.

To make sure it's correct, you can plug in a random number for x. In this case, I checked my work by plugging 2 in for x.

Perimeter = 18(2) + 4 = 36 + 4 = 40

Perimeter = 6(2) + 5 + 6(2) + 5 + 3(2) - 3 + 3(2) - 3 = 12 + 5 + 12 + 5 + 6 - 3 + 6 - 3 = 24 + 10 + 12 - 6 = 40

For question 2, the main idea you need to know is that A = lw. The area of the first rectangle is 6 * 5 = 30. The area of the second rectangle is 6 * 4 = 24. When you add them together, you get 54. The area of the rectangle that is formed when you combine rectangle 1 and rectangle 2 is 6 * 9 = 54. This shows that 6(4) + 6(5) = 6(9)

A penguin walks 10 feet in 6 seconds. At this speed:
AlexFokin [52]

Answer:

1. 75 feet

2. 27 seconds

Step-by-step explanation:

1. If six seconds is equal  to 10 feet that means that 42 seconds is equal to 70 feet (6 X 7 = 42) It also means that 3 seconds is equal to 5 feet. (42 + 3 = 45)

2. If 6 seconds is 10 feet, then 6 X 4 is 40 feet (24) And since 5 feet is equal to   3 seconds then we get 24 + 3 = 27

John and Caleb want to make the high school basketball gym, so they are going to join a gym over the summer. John decided to go
ki77a [65]

Answer:

10 visits

Step-by-step explanation:

John and Caleb want to make the high school basketball gym, so they are going to join a gym over the summer.

Let the number of visits be represented as: x

For John

John decided to go to Planet Fitness, which costs $30 to join, and $5 per visit.

The equation = $30 + $5 × x

= 30 + 5x

For Caleb

Caleb decided to go to Club4Fitness, which just charges $8 per visit.

The Equation = $8 × x

= 8x

We equate both equations to each other

30 + 5x = 8x

Collect like terms

30 = 8x - 5x

30 = 3x

x = 30/3

x = 10

Therefore, John and Caleb would spent the same amount of money after 10 visits.

Surface area and volume of cone
faust18 [17]

The surface area and the volume of the cone is 816.4 km² and 7536 km³ respectively.

<h3>What is volume?</h3>

Volume is the capacity of an object.

To calculate the surface area and volume of the cone shown above, we use equation 1 and equation 2 respectively.

Formula:

  • S = πr√(r²+h²)............. Equation 1
  • V = πr²h.................. Equation 2

Where:

  • S = Surface area of the cone
  • V = Volume of the cone
  • r = Radius of the base of thye cone
  • h = Vertical height of the cone.

From the diagram,

Given:

  • r = 10 km
  • h = 24 km
  • π = 3.14

Substitute these values into equation 1 and equation 2 respectively.

  • S = 3.14×10[√(24²+10²)
  • S = 31.4(√676)
  • S = 31.4×26
  • S = 816.4 km²

Also for the volume of tyhe cone

  • V = 3.14×10²×24
  • V = 7536 km³

Hence, The surface area and the volume of the cone is 816.4 km² and 7536 km³ respectively.
