radius?
Answers
Triangle is missing, so i have attached it.
Answer:
Radius = 10.82
Step-by-step explanation:
From the image attached, the triangle is obviously a right angle triangle and therefore, the missing side (AB) which is the radius can be found via pythagoras theorem.
We are given;
AC = 21
BC = 18
Thus;
|AC|² = |AB|² + |BC|²
21² = |AB|² + 18²
|AB|² = 441 - 324
AB = √117
AB = 10.82

An unknown number is not equal to 3.6 but rounds to 3.6 when rounded to the nearest tenth, what could be the number?
Answers
Answer:
3.55-3.59
Step-by-step explanation:
to round off to the nearest whole number, look at the first number after the decimal, if it is less than 5, add zero to the units term, If it is equal or greater than 5, add 1 to the units term.
So numbers that would be rounded off to 3.6 have to have an hundredth value equal or greater than 5
they include

What is the area of this regular pentagon that has been divided into five congruent triangles?
48 [tex]cm^{2}[/tex]
120 [tex]cm^{2}[/tex]
100 [tex]cm^{2}[/tex]
24 [tex]cm^{2}[/tex]
Answers
Answer:
120 cm^2.
Step-by-step explanation:
The area of one triangle = 1/2 * base * height
= 1/2 * 8 * 6
= 1/2 * 48
= 24 cm^2
So area of the pentagon = 5 * 24
= 120 cm^2.
solve the triangle give the measure of angle G
Answers
Answer:
G = 46 degrees
Step-by-step explanation:
Here, we want to find the measure of angle G
Mathematically, as we can see, what we have is a right triangle
For a right triangle , the sum of angles is 90 degrees
Thus, if we add the two internal angles, we get 90 degrees
Hence;
44 + G = 90
G = 90-44
G = 46 degrees

The surface area of a cone is determined by the equation SA= a rs + a r2, where r is the radius and s is the slant
height. The functions f(x) and g(x) both model the surface area of a cone. One of the functions represents the
surface area of a cone with a radius of 5 and a slant height of x. The other function represents the surface area of a
cone with a slant height of 5 and a radius of x. Which statement correctly matches the description of the function
with the domain of the function in the context of the problem situation?
The function f(x) models the surface area of a cone with a radius of 5, a slant height of x, and has a domain in

B. y=1.13x-2243.65
C. y=1.13x-2233.63
D. y=0.89x-1985.44
Answers
The slope-intercept form of an equation for the line of fit shown in the scatter plot is; C. y=1.13x-2233.63
What is the slope?The slope is the ratio of the vertical changes to the horizontal changes between two points of the line.
We can observe that the line of best fit on this scatters plot passes through points (1997, 13) and (2005, 22).
Using the slope formula,
⇒ slope = (22 - 13)/(2005 - 1997)
⇒ slope = (9)/8
Also, the slope-intercept form of an equation for the line of fit shown in the scatter plot is;
y - 13 = (9)/8(x - 1997)
y = 1.13x -2233.63
Therefore, the slope-intercept form of an equation is y = 1.13x -2233.63

If $500 is invested at 8% annual interest, how much will be in the account after 3 years if it's compounded quarterly?
Answers
Answer:
FV= $634.12
Step-by-step explanation:
Giving the following formula:
Initial investment (PV)= $500
Number of periods (n)= 3*4= 12 quarters
Interest rate (i)= 0.08/4= 0.02
To calculate the future value, we need to use the following formula:
FV= PV* (1 + i)^n
FV= 500*(1.02^12)
FV= $634.12

There is a 3 out of 20 chance that you can win a game. How many "wins" would you predict if you played the game 50 times?
Answers
Answer:
7.5
Step-by-step explanation:
The probability of winning = 3 out of 20 ;
P(winning) = 3/20
Predicted Number of winnings if game is played 50 times ;
P(winning) * number of games played
(3 /20) * 50
0.15 * 50
= 7.5
Predicted Number of winnings = 7.5
