Ans: 1.1 miles more
Speed = distance/time
Time is 1/5 of an hour
1/5 of 1hr = 1/5 or 0.2 hrs
Speed = 16 mph
So, we're after distance.
Distance = speed x time
= 16mph x 0.2
= 3.2 miles
Walks for 3/7 hour at 5 miles per hour :
Time & speed given, distance is what we're after.
(3/7 of 1hr is 3/7)
Distance = speed x time
= 5mph x 3/7
= 15/7 miles or 2.14285...miles
So, distance is about 2.1 miles to 1 d.p
Thus, 3.2 - 2.142... (the full ans) = 1.057... miles
Well, he biked 1.06 miles or 1.1 miles (depending on how you want to round it) more than walking.
Hope this helps!
The equation that could be used to determine the volume of Box B is (B = 14.325cm³ - 5.61cm³) and the volume of Box B is 8.715cm³.
This question is incomplete, the complete question is:
The sum of the volume of two rectangular prisms, box a and box b are 14.325cm cubed. Box a has a volume of 5.61cm.
a. Let B represent the volume of Box B in cubic centimeters. Write an equation that could be used to determine the volume of Box B.
b. Solve the equation to determine the volume of Box B
<h3>What is volume?</h3>
Volume is simply the amount of space that is enclosed within a container.
Given that;
- Sum of the volume of two rectangular prisms A&B = 14.325cm³
- Volume of Box A = 5.61cm³
a)
Let B represent the volume of Box B in cubic centimeters. The equation that could be used to determine the volume of Box B will be;
Sum of the volume of two rectangular prisms A&B = Volume of Box A + Volume of Box B
14.325cm³ = 5.61cm³ + B
B = 14.325cm³ - 5.61cm³
Hence, The equation that could be used to determine the volume of Box B is B = 14.325cm³ - 5.61cm³
b)
To determine the volume of Box B, we solve the equation.
B = 14.325cm³ - 5.61cm³
B = 8.715cm³
Hence, the volume of Box B is 8.715cm³.

Answer:
The y-intercept for this equation is 22.
Step-by-step explanation:
You can solve this quite easily by assigning a zero value to x and solving for y. That is where the curve will intersect the x-axis:
y = 2(x - 3)² + 4
y = 2(x² - 6x + 9) + 4
y = 2x² - 12x + 18 + 4
y = 2x² - 12x + 22
<em>EDIT</em>
<em>Note that the expression above is in standard form, though it can also be factored if needed:</em>
<em>y = 2(x² - 6x + 11)</em>
Now we can solve for an x value of zero:
y = 2(0)² - 12(0) + 22
y = 22
So the y-intercept is 22.
