Answer:
It took Pedro 4.1 hours to reach the lake.
Step-by-step explanation:
What we know:
-Mike hiked to a lake in 4.5 hours
-Mike hikes at an average rate of 4[tex]\frac{1}{5}[/tex] miles per hour
-Pedro hiked to the same lake
-Pedro hikes at a rate of 4[tex]\frac{3}{5}[/tex] miles per hour
So first we can use the information about to Mike to find out how long the journey of the hike is to the lake. So if Mike travels at 4 [tex]\frac{1}{5}[/tex] miles per hour, and reaches the lake in 4.5 hours, we can multiply the rate of the miles he travels per hour, by the number of hours it took to reach the lake, to find the distance. If we do that we find the distance to be 18.9 miles.
Now we find how long it took Pedro to reach the lake. We already have two of the three needed parts of the equation. We have his rate, 4[tex]\frac{3}{5}[/tex] miles per hour, and the distance to the lake, 18.9 miles. Following a similar process as we did Mike, we need to use the information to find the time. We can divide the distance by his rate in order to find this number. If we do this (18.9/4[tex]\frac{3}{5}[/tex]) you get 4.1, so it took Pedro 4.1 hours to reach the lake.
Hope this helps! :)

Step-by-step explanation:
Answer:
16 men
Step-by-step explanation:
3/4 x = 48 3/4 of the people in the band are women. x is the total.
3/4 * 4/3 x = 48 * 4/3 Multiplied both sides by 4/3
x = 64
There are 64 people total.
64 - 48 = 16 men.

Jacob earns $7.25 an hour at his part-time job, and earns $9 each time he mows the lawn for his mother. He graphs the amount of hours he works at his job (xx) and the number of lawns he mows (yy) to determine how to earn at least $300. Which type of boundary line should he use in his graph? A dotted boundary line, because the values on the line should not be included in the solution set. A dotted boundary line, because the values on the line should not be included in the solution set.BA solid boundary line, because the values on the line should not be included in the solution set .A solid boundary line, because the values on the line should not be included in the solution set.CA dotted boundary line, because the values on the line should be included in the solution set .A dotted boundary line, because the values on the line should be included in the solution set. A solid boundary line, because the values on the line should be included in the solution set.
Answers
Answer:
D. A solid boundary line, because the values on the line should be included in the solution set.
Step-by-step explanation:
Given.
Part time = 7.25 per hour.
Mowing of Lawn = 9 each time
Required
Determine the type of boundary
From the question, we understand that x represents the number of hours he worked (part time) and y represent number of lawn he mows.
So, his earnings can be expressed as:
7.25x + 9y
The question also says that he needs to earn atleast 300
Atleast 300 means ≤ 300
So, his earnings can be fully represented as:
7.25x + 9y ≤ 300
When plotting an inequality graph that involves ≤, we make use of a solid line.
This is so, because the values on the solid line are also a part of the line equation.
From the list of given options, option D answers the question.
Find the determinant for the 3 by 3 matrix given. Consider the determinant.
Answers
Answer:
The determinant of the matrix given is -49
Step-by-step explanation:
We are given determinant [tex]\left|\begin{array}{ccc}4&2&-1\\3&0&4\\-3&1&1\end{array}\right|[/tex]
The determinant can be found as follows
[tex]4\left|\begin{array}{cc}0&4\\1&1\\\end{array}\right|-2\left|\begin{array}{cc}3&4\\-3&1\\\end{array}\right|-1\left|\begin{array}{cc}3&0\\-3&1\\\end{array}\right|[/tex]
Now solving:
[tex]4(0-4)-2(3+12)-1(3+0)\\=4(-4)-2(15)-1(3)\\=-16-30-3\\=-49[/tex]
So, determinant of the matrix given is -49

Answer below.
Step-by-step explanation:
The magic constant of the magic square is 42. That means the sum of every column, every file and every diagonal must add up to 42.
The first column has 10 + 11 = 21. We need 42 - 21 = 21 to place in the middle square.
The second row now has 21 + 14 = 35. We add 42 - 35 = 7 in the rightmost square.
The last column now has 7 + 18 = 25. We need 42 - 25 = 17 in the upper square.
Note the diagonal is correct with 11 + 14 + 17 = 42
The first row has 10 + 17 = 27. We need 42 - 27 = 15 more
Finally, the second column has 14 + 15 = 29. To complete 42, we need 42 - 29 = 13
Note the last row has 11 + 13 + 18 = 42.
The magic square is complete. We have attached an image with the completed square.
7. Find the measure of KLM and M
Answers
Answer:
m∠KLM = 64° ; m∠M = 26°
Step-by-step explanation:
(20x + 4)° = (6x + 4)° + (8x + 18)°
20x + 4 = 14x + 22
6x = 18
x = 3
m∠KLM = (20×3 + 4)° = 64°
m∠M = 90° - 64° = 26°
