Answer/Step-by-step explanation:
1. The vertex of am angle is formed when two lines join together. The vertex of the angle shown in the diagram is located outside the circle.(<R)
2. The lines that created <FRT (lines FR & TR) are secants
3. The major arc = FT = 140°
minor arc = QS = 44°
4. Formula of Exterior angles of a circle = (major arc - minor arc)/2
x = (140 - 44)/2
x = 96/2
x = 48°
9514 1404 393
Answer:
C) x = 1/2 cm
Step-by-step explanation:
Apparently, we're to assume the units of x are centimeters. The volume of the cube is the product of its dimensions:
V = x³ = 1/8
Then the value of x is ...
x = ∛(1/8) = 1/∛8
x = 1/2
_____
<em>Additional comment</em>
It can be useful to memorize the squares and cubes of small integers. The cubes you see most often are ...
1³ = 1; 2³ = 8; 3³ = 27; 4³ = 64; 5³ = 125; 6³ = 216; 7³ = 343
Answer:
x = 22, y = 22/7
Step-by-step explanation:
solve for y using first equation:
-2 + 3y = 20
3y = 22
y = 22/7
substitute 22/7 into second equation:
7y = x
7(22/7) = x
x = 22
Answer:
The answer is 4/9
Step-by-step explanation:
Hi. Here's the work.
First turn everything into an improper fraction.
÷
=
÷ 
To divide fractions we multiply by the flipped version of the fraction, or the reciprocal.
÷
= 
Now we just multiply the fractions!
= 
The answer is therefore 4/9. Please mark brainliest if possible and i hope you get a good grade on your homework. ;)
Let the average of the other nine cities be x, then the population of the nine districts is 9x. The total population of the city is a + 9x. But a = 3x. Hence, the total population is 3x + 9x = 12x.
Therefore, the percent of the city's population living in district a is 3x/12x * 100 = 25%
