Answer:
B. 50%
Step-by-step explanation:
Step by step by me I guess
P = 4a.....this is the perimeter of a square
P = 4(180)
P = 720 ft
and if the spray cost 0.11 per ft......720 * 0.11 = 79.20 rounded to the nearest dollar is $ 79 <==
Answer:
X > 40
Step-by-step explanation:
Given that:
Let number of coins in her collection is more Than 40
To represent the number of coins in Melissa's collection as an inequality :
Let total number of items in her collection = X
Coins in her collection > 40
Hence, coins in her collection can be represented as :
X > 40
Answer:
centre (5, 6 ) , r = 
Step-by-step explanation:
the equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k ) are the coordinates of the centre and r the radius
given
x² + y² - 10x - 12y + 24 = 0 ( collect x and y terms together and subtract 24 from both sides )
x² - 10x + y² - 12y = - 24
using the method of completing the square
add ( half the coefficient of the x / y terms)² to both sides
x² + 2(- 5)x + 25 + y² + 2(- 6)y + 36 = - 24 + 25 + 36
(x - 5)² + (y - 6)² = 37 ← in standard form
with centre (h, k ) = (5, 6 ) and r =
Answer:
20
Step-by-step explanation:
start by dividing 18 from 120(to find the amount of 18's in 120)
120 / 18 = 6.<u>6</u>
meaning there are 6.<u>6</u> sets of 18 in 120
multiply 3 by 6.<u>6</u>(since there's 3 miles for every 18 minutes)
3 x 6.<u>6</u> = 20
