Which of the following is the best approximation of the area of a circle whose diameter is 14 feet?

88 square feet
44 square feet
616 square feet
154 square feet

Answer:

Each side of the octagon a length of 6 cm

Step-by-step explanation:

Divide the perimeter by the amount of sides the shape has.

48 ÷ 8 = 6

Answer:

6in²

Step-by-step explanation:

the problem says the two triangular prisms are congruent.

the first triangle's volume is 90in³ and the height of the second triangular prism is 15. we use the formula fro the volume of the shape:

V=B * h

we substitute the values we know:

90in³=B*15

90/15 = B

6in²= B

So the area of the base is 6in²

Answer:

C

Step-by-step explanation:

We want a line of best fit, which means we want to create a line that the data points will lie closest to.

One thing we can do is find the slope between the bottom-leftmost point and the top-rightmost point. This is because if we were to draw a line connecting these two, it will cut through the data quite well.

Those two points are (9, 15) and (16, 18), so the slope is change in y divided by the change in x:

(18 - 15) ÷ (16 - 9) = 3 ÷ 7 ≈ 0.4

Eliminate A and B.

Now we need to determine the y-intercept. This needs no calculations; simply look at the graph: there's no way a line cutting through the y-intercept point of (0, 18) will perfectly match the data points; instead it must be a y-intercept lower than 18. So, eliminate D.

The answer is C.

Answer:

C

Step-by-step explanation:

The slope of the line of best fit should be around:

(18-15)/(16-10) = 0.5

And

The y-intercept would be less than 15

Therefore, option C is the most suitable option

Answer:

84.6

Step-by-step explanation:

135c + 273.15 = 408 K

72C + 273.15 = 345 K

100 L over 408 K = V2 over 345 K

V2= 84.6

The volume of the gas when temperature decreases to 72.0 °C is 84.6 L

Volume is a physical quantity that measures the amount of three-dimensional space occupied by matter (solid, liquid, or gas).

Volume is defined as the three-dimensional space occupied by matter or enclosed by a surface. The SI unit of volume is the cubic meter (m³),

Given that, a sample of gas has a volume of 100.0 L at 135 °C, the pressure remains constant, we need to find that what is the volume of the gas when temperature decreases to 72.0 °C

Converting the temperature into Kelvins =,

135C + 273.15 = 408 K

72C + 273.15 = 345 K

100 L / 408 K = V2 / 345 K

V2 = 84.6

Hence, the volume of the gas when temperature decreases to 72.0 °C is 84.6 L

Answer:

220 square centimeters  Option c.

Step-by-step explanation:

There are 6 faces of a rectangular prism, so to find the surface area of the prism, add the area of each faces.

Surface Area = 2(lw + lh + wh)

where, l = Length, w = Width and h = Height of the rectangular prism.

According to the given dimensions

Length = 10 cm

Width = 4 cm

Height = 5 cm

Therefore, the surface area of the given rectangular prism will be,

S.A. = 2((10)(4) + (10)(5) + (5)(4))

       = 2(40 + 50 + 20)

       = 2 (110)

      = 220 cm²

Surface area of the rectangular prism will be 220 cm².

We have been given that a rectangular prism that has a height of 5 cm, a width of 10 cm, and a depth of 4 cm. We are asked to find the surface area of the prism.

We will use surface area of rectangular prism to solve our given problem.

[tex]A=2(lw+wh+hl)[/tex], where,

l = Length,

w = Width,

h = Height.

[tex]A=2(10\text{ cm}\cdot 4\text{ cm}+4\text{ cm}\cdot 5\text{ cm}+5\text{ cm}\cdot 10\text{ cm})[/tex]

[tex]A=2(40\text{ cm}^2+20\text{ cm}^2+50\text{ cm}^2)[/tex]

[tex]A=2(110\text{ cm}^2)[/tex]

[tex]A=220\text{ cm}^2[/tex]

Therefore, the surface area of the given prism would be [tex]220\text{ cm}^2[/tex] and option C is the correct choice.

Given Function A with points (–5, –2), (–5, 7) and Function B with points (7, –5), (–2, –5) represent linear functions, thus:

Function A has an undefined slope: no slope

Equation for line A would be: x = -5

Function B has a slope value of: 0.

Equation for line B is: y = -5

Recall:

Thus:

Linear Function A with the points (–5, –2), (–5, 7):

[tex]Slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{7 -(-2)}{-5 -(-5)} \\\\[/tex]

[tex]m = \frac{9}{0}[/tex] (can't divide. Undefined)

The equation for function A will therefore be written as: x = -5

Linear Function B with the points (7, –5), (–2, –5):

[tex]Slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-5 -(-5)}{-2 - 7} \\\\[/tex]

[tex]m = \frac{0}{-9} = 0[/tex]

The equation for function A will be written as: y = -5

In summary, given Function A with points (–5, –2), (–5, 7) and Function B with points (7, –5), (–2, –5) represent linear functions, thus:

Function A has an undefined slope: no slope

Equation for line A would be: x = -5

Function B has a slope value of: 0.

Equation for line B is: y = -5

Answer:

72 cm

Step-by-step explanation:

The area (A) of a kite is calculated as

A = [tex]\frac{1}{2}[/tex] × d₁ × d₂ ( d₁ and d₂ are the diagonals )

Here A = 900 and d₁ = 25, thus

Answer:

Step-by-step explanation:

If A is S then S is A so using Trin's method...you can find 18x*760+y

The correct answer is:

The possible value for the 6th term is 40. Thus, the answer is B) 70.

To find the common ratio (r) of the geometric sequence, divide the 7th term by the 5th term:

[tex]\[ r = \frac{40}{160} = \frac{1}{4} \][/tex]

Now, we can find the 6th term (T6) using the common ratio and the 5th term:

[tex]\[ T6 = T5 \times r = 160 \times \frac{1}{4} = 40 \][/tex]

So, the 6th term could be 40. Therefore, the answer is:

B) 70
