Answer:
8 minutes, 30 seconds, by the look of the graph.
Step-by-step explanation:
At a distance of 10 inches, 1 minute has passed.
So multiply that by 8.5, and you have 85 inches travelled over 8 minutes, 30 seconds.
3.1 Solve<span> : </span>4x2<span>+3 = 0. Subtract 3 from both sides of the equation : </span><span>4x2 = -3</span>. Divide both sides of the equation by 4: x2<span> = -3</span>/4 = -0.750. When two things are equal, their square roots are equal. Taking the square root of the two sides of the equation we get: x = ± √ -3/4. In Math, i is called the imaginary unit. It satisfies i 2<span> =-1.</span>
A/b ÷ d/c
a/b * c/d
4x/ x² + 5x -6 * x² + 7x + 6/ x² - 11x + 28 factor
4x/ (x+6)(x-1) * (x+6)(x+1)/ (x-7)(x-4) (x+6) cancels out
4x (x+1) / (x-1)(x-7)(x-4)
Answer:
(A)
(D)
Step-by-step explanation:
Given that:


Therefore, A and D are equivalent
When a problem says that the price was increased by 100% + n%, it means you add on n% percent of the original price. In this problem, the original price was $35. The new price is 115% percent of the original price. So all we need to do is find 15% of the original price and add it onto the original price to find the new price.
$35 * 0.15 = $5.25
$35 + $5.25 = $40.25
The new price of the shoes is $40.25.
