Step-by-step explanation:
Answer:
1 11/12
Step-by-step explanation:
convert to common denominators.
1 1/6 = 7/6 = 14/12
3/4 = 9/12
14+9=23
23/12
1 11/12

Answer: 21
Step-by-step explanation:
Take 12 and multiply it by 1.75 (12x1.75) and you’ll get 21
Answer:
t = 0.722 seconds
Step-by-step explanation:
Given in the question that an equation
h = -16t² + 6t + 4
here h is the height
t is the time
To solve this question we need to substitute height with zero because at ground level height is zero
<h3>h = 0</h3>
0 = -16t² + 6t + 4
<em>a = -16</em>
<em>b = 6</em>
<em>c = 4</em>
Formula to use
t = -b±√(b²-4ac) / 2a
Plug values in the formula
t = -6 ± √36-4(-16)(4) / 2(-16)
t = 6±2√73 / 32
t = 6+2√73 / 32 or t = 6-2√73 / 32
t = 0.722 or t = -0.347
since time can't be in negative so we reject t = -0.347
Step 1
Sketch a diagramatic representation of the question.
Step 2
Based on the diagram calculate the distance from the top of the mountain to the deepest part of the trench (D).
