A train traveled from one city to another city in 4 hours at a speed of 70 mph.
The retum trip was made in 5 hours. Find the speed for the return trip.
Answer:
56miles/hr
Step-by-step explanation:
Given parameters:
Time taken for the to travel = 4hrs
Speed of the train = 70mph
From this data, let us find the distance of the trip;
Distance =Speed x time
Therefore, insert the parameters;
Distance = 70mph x 4hr = 280miles
Now;
Return trip took, 5hrs,
Speed = ?
Speed = [tex]\frac{distance}{time}[/tex]
Insert the parameters and solve;
Speed = [tex]\frac{280}{5}[/tex] = 56miles/hr
Subtract and Simplify your answer 12/24 - 1/6
Answer:
The answer would negative 4

A farmer with 5000 feet of fencing wants to enclose a rectangular field and then divide it into two plots by adding a fence in the middle parallel to one of the sides. Using the function A(x) , analytically find the WIDTH of the field that would maximize its area. (Round your answer to the nearest whole number)
Answer:
The required width of the field that would maximize the area is = 1250 feet
Step-by-step explanation:
Given that:
The total fencing length = 5000 ft
Let consider w to be the width and L to be the length.
Then; the perimeter of the rectangular field by assuming a parallel direction is:
P = 3L + 2w
⇒ 3L + 2w = 5000
3L = 5000 - 2w
[tex]L = \dfrac{5000}{3} - \dfrac{2w}{3}[/tex]
Recall that:
The area of the rectangle = L×w
[tex]A(w) = ( \dfrac{5000}{3}-\dfrac{2}{3} ) w[/tex]
[tex]A(w) = \dfrac{5000}{3}w-\dfrac{2}{3} w^2[/tex]
Taking the differentiation of both sides with respect to t; we have:
[tex]A' (w) = \dfrac{5000}{3} - \dfrac{2}{3} ( 2 w)[/tex]
[tex]A' (w) = \dfrac{5000}{3} - \dfrac{4w}{3}[/tex]
Then; we set A'(w) to be equal to zero;
So; [tex]\dfrac{5000}{3} - \dfrac{4w}{3}=0[/tex]
5000 = 4w
w = 5000/4
w = 1250
Thus; the required width of the field that would maximize the area is = 1250 feet
Also, the length [tex]L = \dfrac{5000}{3} - \dfrac{2w}{3}[/tex] can now be :
[tex]L = \dfrac{5000}{3} - \dfrac{2(1250)}{3}[/tex]
L = (5000 -2500)/3
L = 2500/3 feet
Suppose, the farmer divides the plot parallel to the width; Then 2500/3 feet = 833.33 feet and the length L = 1250 feet.

C. Corresponding angles theorem.
D. If two lines are parallel, then alternate exterior angles are
congruent.
Answer:
Option B: If two lines are parallel, then alternate interior angles are
congruent.
Step-by-step explanation:
Notice that angles 3 and 6 are INTERNAL relative to the parallel lines, that is located in between the parallel lines. They are also alternate angles. Therefore, the correct answer is:
"If two lines are parallel, then alternate interior angles are congruent."
A turkey cost $1.05 per pound. There are going to be fifteen people at Thanksgiving dinner. Plan for each person to eat two, 3/8-pound servings if turkey. How much will the turkey for Thanksgiving dinner cost?
Answer:
5.90625
Step-by-step explanation:
15*3/8=5 5/8
5 5/8=5.625
1.05*5.625=5.90625
The cost of the turkey for Thanksgiving dinner is $ 11.8125
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the cost of 1 pound of turkey = $ 1.05
Total number of people at the Thanksgiving dinner = 15 people
The number of servings for each person = 2 servings
The amount of turkey servings for each person = 2 x 3/8 pound servings
= 3/4 pound servings
Now , the equation will be
So , the total cost of 3/4 pound servings of turkey =
3/4 x cost of 1 pound of turkey
The total cost of 3/4 pound servings of turkey = 3/4 x 1.05
= $ 0.7875
Now , the cost for 15 people at the Thanksgiving dinner =
15 x total cost of 3/4 pound servings of turkey
The cost for 15 people at the Thanksgiving dinner = 15 x 0.7875
= $ 11.8125
Hence , The cost of the turkey for Thanksgiving dinner is $ 11.8125
