Answer:
x = 9
Step-by-step explanation:
7x - 1 = 62
add on to each side and you get 7x = 63
divide both sides by seven to get x = 9
Yes, the two ratios are proportional to each other. The multiplier from the first ratio to the second ratio is 3. For example, 4.2 x 3 = 12.6 and 1.5 x 3 = 4.5. Basically, to figure out if two ratios are proportional to each other, just divide the smaller number into the bigger number for both corresponding numbers. If they're the same ---> Proportional. If they're not the same ---> Not Proportional
Answer:
Step-by-step explanation:
Arc length of the circle is given by,
Arc length = 
Area of the sector of a circle =
22). Arc length of the circle having central angle = 
= 60°
Arc length = 
= 
= 7.33 cm
23). Arc length of the circle having central angle = 225°
Arc length = 
= 12.5π
= 39.27 km
24). Central angle = 
= 
= 225°
Area of the sector = 
= 43.20 yd²
25). Area of the sector = 
= 65.97 yd²
- So since we have to use that to figure out it's product. Then we should use an equation and blah, blah... Nishishi...
- ( a + b ) ( a - c )
= a² + ba - bc - ac
- ( p+5 )( p-2 )
= p² - 2p + 5p - 10
--<u>p² + 3p - 10</u>
