Answer:
12.0 cm
Step-by-step explanation:
The Pythagorean theorem applies:
(12 cm)² +b² = (17 cm)²
b² = (289 -144) cm² = 145 cm²
b = √145 cm ≈ 12.04 cm
b ≈ 12.0 cm . . . . rounded to 1 decimal place
ANSWER= 14 oz bottle
6.98 - 2 = 4.98 (14oz)
19.99 - 2 = 17.99 (28oz)
28 is triple the price when it’s only two times bigger
Answer:
x = ±i sqrt(3/2)
Step-by-step explanation:
2x^2+7 = 4
Subtract 7 from each side
2x^2+7-7 = 4-7
2x^2 = -3
Divide by 2 on each side
2x^2/2 = -3/2
x^2 = -3/2
There is no real solution, only imaginary solutions
Taking the square root of each side
sqrt(x^2) = sqrt(-3/2)
x = ±i sqrt(3/2)
To solve this, set up a proportion where X is the amount that 120 lawn mowers would cost. It would look like

.
Then cross-multiply to get 40x = 120(4776) or 40x = 573120. Now divide each side by 40 to isolate the variable.
X = 14328.
120 lawn mowers would cost $14,328.
The cost of the burger is $6
