What is the surface area of the square pyramid represented by the net below?
A: 48 cm
B: 96 cm
C: 64 cm
D: 112 cm
Answers
Answer: C: 64 cm
Step-by-step explanation:
The square has a a side of 4 centimeter meaning the area would be 16 cm. The area of the triangle is determined by half of the area of the base times the height. This mean that 4 x 6 = 24 and then 24/2 = 12. 4 x 12 = 48 (due to four triangles). 48 + 16 = 64. It is C: 64 cm

The value of a computer decreases with its age, until it is worth nothing. A computer that was purchased new (age 0 years) for

The value of the computer after 8 years is $ type your answer...
After type your answer.
years the computer will be worth nothing.
Answers
Answer:
v(x)=2200-N*110
the value of computer after 8 years is 1320
Step-by-step explanation:
at 0 years the value is 2200
after 6 years the value is 1540
we should calculate how much the value of the computer decreases in one year , so we can do an interpolation to determine the value of the computer after 1 year and it is 2090$ . so, 2200-2090=110$ that means in one year the value of computer decreases 110$ so the function is v(x)=2200-n*110
where n is number of years
so after 8 years : v(8)=2200-8*110=1320$

Answer:
Between 0 and 1 goes 1/4 then after that is 5/8 then between the 1 and the 2 put 1 and 3/8/
Step-by-step explanation:
The reason for this is simply smallest to biggest. Which is bigger 1/4 or 5/8? Well if you want you can put it into a decimal: 1/4 = 0.25 and 5/8 equals 0.625. So 0.25 is closer to 1 and then 5/8 is the next closest to 1 but it is closer to 2. And lastly 1 and 3/8 is more then 0 and it's more then 1 so it goes in between 1 and 2 This is how it goes: 0 1/4 5/8 1 1 and 3/8 2

The circumference of this tabletop is 24π inches, Which of the following best describes how to determine the area of the tabletop?
A) Multiply 2(24) to calculate the diameter. Then multiply the diameter by π
B Find half of 24 to calculate the radius. Then multiply the radius by π.
C Multiply 2(24) to calculate the diameter. Then square the diameter and multiply the result by it π
D Find half of 24 to calculate the radius. Then square the radius and multiply the result by π.
Answers
Answer:
D Find half of 24 to calculate the radius. Then square the radius and multiply the result by π.
Step-by-step explanation:
Given that circumference of circle is: [tex]24 \pi[/tex]
The formula for circumference of circle is:
[tex]C = 2\pi r[/tex]
Comparing both formulas, we get
[tex]24\pi = 2\pi r\\24 = 2r\\r = \frac{24}{2}\\r = 12[/tex]
The radius is obtained by dividing 24 by 2.
We also know that the area of circle is:
[tex]A = \pi r^2[/tex]
The radius is being squared and then multiplied by pi to get the area.
Hence,
The correct answer is:
D Find half of 24 to calculate the radius. Then square the radius and multiply the result by π.

Answer:
x=0 y=-11 (0,-11)
Step-by-step explanation:
1. take what y equals (3x-11) and plug it in for y in the second equation
Should look like this: O= 6x-2(3x-11)-22
2. Then distribute O=6x-6x+22-22
3. Then combine like terms O= 0 the 22's cancel out as well as the x's
x= 0
4. plug 0 in for x in the first equation y=3(0)-11
5. y= -11
6. x=0 y=-11 (0,-11)

a) The area of the picture is the product of its dimensions:
(18 cm)² = 324 cm²

b) The area of the board is 4 times that:
board area = 4×324 cm² = 1296 cm²

c) The dimensions of the square board are the square root of its area:
√1296 = √(4×324) = (√4)(√324) = 2×18 = 36 . . . . cm
The board is 36 cm square.
