Answer:
44.44 mph
Step-by-step explanation:
[tex]speed = \frac{distance}{time} = \frac{distanceTo + distanceFrom}{time1 + time2} = \frac{2d}{\frac{d}{40} + \frac{d}{50} }[/tex]
= [tex]\frac{2d}{\frac{5d + 4d}{200} } = \frac{2d}{\frac{9d}{200} }[/tex]
= 2d * [tex]\frac{200}{9d}[/tex]
= 400 / 9
= 44.44
Answer:
44.4 miles per hour
Step-by-step explanation:
d = the distance between cities
t 1= the time from home to the city
t 1 = the time . from the city to home
2d/t1 + t2 = 2d/ d/40 + d/50
=2d/5d+4d =2d/9d
divide both sides by 200
=2d * 200/9d =400/9
= 44.4

lamont is trying to determine how many $5 and $10 bills he needs to make $300 in total he has 35 bills. If x represents the number of $5 bills he has and y represents the number of $10 bills use the graph below to determine how many of each bill he has
Answer: 10 $5 bills, and 25 $10 bills.
Step-by-step explanation:
Let's define the variables:
F = number of $5 bills.
T = number of $10 bills.
We know that he wants to make $300 in total, then we have:
F*$5 + T*$10 = $300
And we also know that in total there are 35 bills, then:
F + T = 35.
So we have the system of equations:
F*$5 + T*$10 = $300
F + T = 35
To solve this, the first step is isolate one of the variables in one of the equations, i will isolate F in the second equation to get:
F = 35 - T
Now we can replace that in the other equation, and get:
(35 - T)*$5 + T*$10 = $300
Now we can solve this equation for T.
$175 - T*$5 + T*$10 = $300
T*$5 = $300 - $175 = $125
T = $125/$5 = 25
and:
F = 35 - T = 35 - 25 = 10
Then he has:
10 $5 bills, and 25 $10 bills.
Jackson buys a softball for $15 plus a 6% tax. Avery buys a volleyball for $13 plus a 6% tax. Enter the difference in the amount Jackson and Avery paid, including tax. Round your answer to the nearest cent.
Answer:
The answer is that the difference in the amount that Jackson and Avery paid including tax is $1.31.
Step-by-step explanation:
First, you have to calculate the amount they paid including the tax by finding the 6% of each price and adding this amount to the price:
-Jackson: $15*6%=0.09
$15+$0.09=$15.09
-Avery: $13*6%=$0.78
$13+$0.78=$13.78
Now, you have to subtract to find the difference:
$15.09-$13.78=$1.31
According to this, the answer is that the difference in the amount that Jackson and Avery paid including tax is $1.31.

Describe your approach to solving a given triangle. Include specific details about what you look for and how you start the problem. What are the important pieces of information that affect how you solve the triangle?
(edginuity)
Answer:
In order to solve a right triangle, you must first figure out which angle is the right angle. Knowing the right angle will also tell you which side is the hypotenuse, since the hypotenuse will always stand opposite the right angle. In this text, for the sake of consistency, in all triangles we will designate angle C as the right angle, and side c and the hypotenuse. To finish solving a right triangle, you then must either know the lengths of two sides, or the length of one side and the measure of one acute angle. Given either of these two situations, a triangle can be solved. Any further information about a triangle may be helpful, but it is not necessary.There are four basic techniques to use in solving triangles.Using the Pythagorean Theorem, once two sides are known, the third side can be calculated.Using the fact that the acute angles of a right triangle are complementary, once one acute angle is known, the other can be calculated.Using the definitions of the trigonometric functions, any two parts of a triangle can be related in an equation to equal a third part.Using the definitions of the inverse trigonometric functions, any two sides of a triangle can be related in an equation to equal the inverse function of an unknown acute angle

which of the lines graphed has a slope of 1 and a y-intercept of -3?
Answer: The attached image (Graph 4) is the correct graph.
Step-by-step explanation:
1. Find the graph with the point (0, -3), the y-intercept. This eliminates all but two graphs.
2. Out of the two graphs you have narrowed down the options to, choose the graph with the positive slope (slope of 1). Since graph 3 has a negative slope amd graph 4 has a positive slope and still satisfies the correct intercept, the 4th graph is the correct option.
Marissa has 2.5 hours of swim practice per day. She practices 4 days per week. The swimming season is 14 weeks long.
How many total hours of swimming practice does Marissa have in one swimming season?
Answer: 140
Step-by-step explanation: 2.5 x 4 = 10
10 x 14 = 140
you multiply the amount of hours she swims for 4 days and then multiply those hours by 14 because the swimming season is 14 weeks long.
Find the slope of the line that passes through (10, 5) and (7, 4).
Answer: M (slope) = -1 / -3 = 0.3
Step-by-step explanation:
Answer:
1/3
Step-by-step explanation:
Slope=y1-y2/x1-x2
Where (X1,y1) is (10, 5) and (X2,y2) is (7, 4).
So
Slope= 5-4/10-7
= 1/3
So slope is 1/3
The smiths went to Larosa's for dinner and spent $42.50 on dinner. There is a 6.5% tax and they want to give a tip of 20% before the tax is added. What is the total price of their bill?
Answer:
Step-by-step explanation:
cost of dinner = $42.5
Tax = 6.5%
Tip = 20%
Total amount percent on food = 26.5%
Amount paid on the original price = 26.5% of $42.5
Amount paid on the original price = 0.265*42.5 = $26.5625
Total price of the bill = $42.5 + $26.5625
Total price of bill = $69.0625

Given that:
Width of wooden board = 6 inches
Number of boards required to build a fence of 150 inches long if there are no gaps :
The lenght of fence / width of wooden board
= 150 inches / 6 inches
= 25 wooden boards

It takes Frank 2 hours to build a fence. It takes Tom 9 hours to build the same fence. How long would it take to build the fence if Frank and Tom built the fence together?
Answer:
5 1/2 hours
Step-by-step explanation:
You would have to add 2 and 9 and then divide by 2. (Find the average of the two)
2 + 9 = 11
11 / 2 = 5.5
So if you add their times then divide you receive and average of five and a half hours.
