Answer:
33.49
Step-by-step explanation:
The formula for volume of a sphere is 4/3 × π × radius³
The radius in this case is 2
2³ = 8
4/3 × 8 = 10 2/3
10 2/3 × 3.14 ≈ 33.49
You can also right it as (10 2/3) × π
A triangle has vertices at A(–2, 4), B(–2, 8), and C(6, 4). If A prime has coordinates of (–0.25, 0.5) after the triangle has been dilated with a center of dilation about the origin, which statements are true? Check all that apply.
- The coordinates of C prime are (0.75, 0.5).
- The coordinates of C prime are (1.5, 1).
- The scale factor is One-eighth.
- The scale factor is 8.
- The scale factor is One-fourth.
- The scale factor is 4.
- The coordinates of B prime are (–0.25, 1).
- The coordinates of B prime are (–0.5, 2).
Answer:
i think it is C
Step-by-step explanation:
Answer:
When we are given a point P(x, y) centered at origin with a scale factor of k, then the dilated point will be given by P' (kx, ky)
Applying the concept:
Given A(-2, 4) and A'(-0.25, 0.5), which means , and .
Substituting -2 for x in the equation , we get the below equation:
Now we need to find B' and C' by multiplying 0.125 with the x-coordinate and y-coordinate.
-----
x-coordinate of B is -2, y-coordinate of B is 8
x-coordinate of B'
y-coordinate of B'
So
-----
x-coordinate of C is 6 and y-coordinate of C is 4
x-coordinate of C'
y-coordinate of C'
So
Conclusion:
The below are the TRUE statements:
(i) The coordinates of C' are (0.75, 0.5)
(ii) The scale factor is 1/8
(iii) The coordinates of B' are (–0.25, 1).

The temperature in degrees Fahrenheit, F, is related to the temperature in degrees Celsius, C, by the equation
F=9/5 C+32
1.In the Sahara desert, temperatures often reach 50 degrees Celsius. How many degrees Fahrenheit is this?
2.In parts of Alaska, the temperatures can reach -60 degrees Fahrenheit. How many degrees Celsius is this?
3.There is one temperature where the degrees Fahrenheit and degrees Celsius are the same, so that C=F. Use the expression from the equation, where F is expressed in terms of C, to solve for this temperature.
The temperatures are in 50° Celsius, -60° Celsius and -40° Celsius when the temperatures are 122° Fahrenheit, -76° Fahrenheit and -40° Fahrenheit respectively.
What is the temperature?Temperature is a measurement of an object or material's warmth or coldness and an expression of thermal energy.
Given, the conversion expression of degrees Fahrenheit to degree Celsius.
The expression is,
F = (9/5)C + 32
For the option 1,
C = 50° Celsius
Then F = 9 x 50/5 + 32
= 90 +32
= 122° Fahrenheit
For the option 2,
C = -60° Celsius
Then F = 9 x -60/5 + 32
= -108 + 32
= -76° Fahrenheit
For the option 3,
C = F
Then F = 9F / 5 +32
F - 9F/5 = 32
-4F / 5 = 32
F = -160/4
F = -40° Celsius.
Therefore, the temperatures are 122° Fahrenheit, -76° Fahrenheit and -40° Fahrenheit when the temperatures are in 50° Celsius, -60° Celsius and -40° Celsius respectively.

Answer:Pi
Step-by-step explanation:
The ratio of circumference of circle to its diameyer is the number π ,a mathematical constant, commonly approximated as 3.14159. It has been represented by the Greek letter "π" since the mid-18th century, though it is also sometimes spelled out as "pi".
Please provide explanation IF you can. Very Confused!!
Answer:
41.63
Step-by-step explanation:
Circumference = 2pi(r)
26.5 / 2 = 13.25 (radius)
2pi(13.25) = 83.25 (circumference of the full circle)
83.25 / 2 = 41.625 or 41.63

Answer:
y-intercept: (0,4)
Slope: -1/3
Step-by-step explanation:
y-intercept: (The y-axis is the vertical axis.) this is where the line crosses the y-axis. (This always occurs when x = 0.) From the graph, the purple line crosses the y-axis at 4 therefore: y-intercept = (0,4)
slope:
slope = rise / run
this means slope = y/x
first step is to locate to places along the purple line that cross the grid boxes neatly. this occurs at (-3,5), (0,4), and (3,3).
Taking any two of the three intersections listed above one can find the slope of a line. To demonstrate solving, we will solve for slope three way using the same method, different points:
___________________________________
Option 1: (-3,5), (0,4)
[With ordered pairs, x is always listed first followed by y]
slope between two points = change in y / change in x
so slope = (5 - 4) / (-3 - 0)
slope = 1/-3
slope = -1/3
___________________________________
Option 2: (0,4), (3,3)
[With ordered pairs, x is always listed first followed by y]
slope between two points = change in y / change in x
so slope = (4 - 3) / (0 - 3)
slope = 1/- 3
slope = -1/3
___________________________________
Option 3: (-3,5), (3,3)
[With ordered pairs, x is always listed first followed by y]slope between two points = change in y / change in x
so slope = (5 - 3) / (-3 - 3)
slope = 2/- 6
reduce to:
slope = 1/- 3
slope = -1/3
___________________________________
NOTES: a tip to check if a slope will be positive or negative can be found by just looking at the graph. If the lower part of the line is to the left, the slope will be positive. If the lower part of the line is to the right (as in question), the slope will be negative.
what is the answer?
R2 + 8 =
Because there is no sum we can’t find the variable (what R equals) so the answer can only be two things if you are factoring the equation the answer would be 2(R+4). If you are trying to simplify it would remain R2+8.
