Allan has to make a delivery that is 1200 miles away. by law, he can only drive his truck for 20 hours without taking a break. What must allan's average speed be if he wants to make the delivery before he has to take a break?
Answers
Answer:
Step-by-step explanation:
60 average speed
The delivery must be completed by Allan before he needs to stop, thus his average pace must be at least 60 mph.
What is the average rate of change?It is a measure of how much the function changed per unit, on average, over that interval. It is derived from the slope of the straight line connecting the interval's endpoints on the function's graph.
If Allan has to make a delivery that is 1200 miles away and can only drive for 20 hours without taking a break,
we need to find his average speed to see if he can make the delivery before the 20-hour mark.
We can use the formula:
average speed = total distance / total time
We know the total distance is 1200 miles.
To find the total time, we need to know Allan's maximum driving time before taking a break. Let's assume that Allan will take a break after driving for 20 hours.
So, Allan's total time available to make the delivery is 20 hours.
Therefore,
average speed = total distance / total time
average speed = 1200 miles / 20 hours
average speed = 60 miles per hour
Allan's average speed must be at least 60 miles per hour to make the delivery before he has to take a break.

A 20 inch long piece of rope is approximately 0.5 meters long. What is the length, in inches, of a rope that is 2.5 meters long, rounded to the nearest tenth?
Answers
Answer:
100 inches (using the given data)
98.43 (using exact numbers)
Step-by-step explanation:
1 inch = 2.54 centimeters
20 inches = 50.8 centimeters, but for the purpose of answering this question we will assume that 20 inches = 0.5 meters (instead of 0.58).
we must solve the following equation:
20 inches / 0.5 meters = X inches / 2.5 meters
(2.5 meters x 20 inches) / 0.5 meters = X inches
20 inches x 5 = X inches
100 inches = X inches
if we do the exact calculation, 2.5 meters in inches = 250 centimeters / 2.54 centimeters per inch = 98.43 inches
The measures of the Angles of a triangle are shown in the figure below
Answers
Answer:
x = 22°
Step-by-step explanation:
The angles of a triangle add to 180°, so:
69 + (3x - 4) + (3x - 17) = 180
(3x - 4) + (3x - 17) = 111
6x - 21 = 111
6x = 132
x = 22
Answer:
22
Step-by-step explanation:
(3x - 4)° + (3x - 17)° + 69° = 180°
6x - 21 + 69 = 180
6x + 48 = 180 ⇒ x = 22
Determine f(-2/3) for the function f(x)=3x²+2x+1
Answers
Answer:
1
Step-by-step explanation:
To evaluate, substitute x = - [tex]\frac{2}{3}[/tex] into f(x), that is
f(- [tex]\frac{2}{3}[/tex] )
= 3(- [tex]\frac{2}{3}[/tex] )² + 2(- [tex]\frac{2}{3}[/tex] ) + 1
= 3([tex]\frac{4}{9}[/tex] ) - [tex]\frac{4}{3}[/tex] + 1
= [tex]\frac{4}{3}[/tex] - [tex]\frac{4}{3}[/tex] + 1
= 0 + 1
= 1
Answer:
1
Step-by-step explanation:
f(x) = 3x² + 2x + 1
f(-2/3) = 3x² + 2x +1
f(-2/3) = 3(-2/3)² + 2(-2/3) + 1
Substitute the value in for all the x's
f(-2/3) = 3(4/9) + 2(-2/3) + 1
f(-2/3) = 12/9 + (-4/3) + 1
f(-2/3) = 4/3 + (-4/3) + 1
Subtracting 4/3 by (-4/3) gets you 0 so I didn't write it down.
f(-2/3) = 1
So, the answer I got is 1

what is the simplified form of the fraction 7/28
Answers
Answer:
1/4
Step-by-step explanation:
7 divided by 24 = 4 so it gets reduced to 1 and then 1/4
The solution is: 1/4 is the simplified form of the fraction 7/28.
Here, we have,
given that,
the fraction is: 7/28
now, we divide each fraction numerator and denominator by a common divisor of them,
here, we know that,
7 * 1 = 7
7*4 = 28
so, the gcf of 7 and 28 = 7
we divide each fraction numerator and denominator by a common divisor 7,
we will get:
7/28 = 1/4
7 divided by 28 = 4 so it gets reduced to 1 and then 1/4.
Hence, The solution is: 1/4 is the simplified form of the fraction 7/28.

Write an expression for the sequence of operations described below. add b to a, then multiply 9 by the result Do not simplify any part of the expression.
Answers
Answer:
9a+9b
Step-by-step explanation:
Add b to a and multiply 9 by the result without simplifying any part of the expression.
Not simplifying an expression in algebra means not organizing or grouping like terms in the algebraic expression in such a way as to make it more understandable. It is not required in this case. Hence,
We add b to a
=a+b
We multiply 9 by the result
=9 * a+b
=9(a+b)
= 9a+9b
A ball falls from a window. It's height, as a function of time, is modleled by y= -4.9x2 +12. Which statement best describes the function? A. Not enough information is given to decide.
Answers
Answer:
Step-by-step explanation:
Given the the height covered by the ball modeled by the equation
y= -4.9x²+12
Since we are not told what to find, we can as well find the time taken by the ball to reach the ground.
The ball hits the ground when y = 0. Substitute y = 0 into the equation and calculate x;
y= -4.9x²+12
0 = -4.9x²+12
Subtract 12 from both sides
0-12 = -4.9x²+12-12
-12 = 4.9x²
x² = -12/4.9
x² = 2.448
x = √2.448
x = 1.57s
Hence we can say that the ball hits the ground after 1.57s.
