Answer:
It took Pedro 3.81 hours to reach the lake.
Step-by-step explanation:
Time taken by Mike to hike a lake = 4.5 hours
Average rate of Mike while hiking the lake = [tex]2\frac{1}{5}\ miles/hr[/tex]
Formula for distance can be seen as:
[tex]Distance = Speed\times Time[/tex]
Distance traveled by Mike = [tex]4.5 \times 2\frac{1}{5} = 4.5\times \frac{11}{5} = 9.9\ miles[/tex]
Rate of Pedro while hiking the same distance = [tex]2\frac{3}{5}\ miles/hr = \frac{13}{5}\ miles/hr[/tex]
Given that, Pedro also travels the same distance.
And we have to find the Time.
[tex]Time = \dfrac{Distance}{Speed}[/tex]
[tex]Time = \dfrac{9.9}{\frac{13}{5}}\\\Rightarrow Time = \dfrac{9.9\times 5}{13} = \bold{3.81\ hours}[/tex]
It took Pedro 3.81 hours to reach the lake.
Simplify the expression.

2. 12 2/9
3. 11 9/23
4. 12 9/23
Answer:
2. 12 2/9
Step-by-step explanation:
Because of the choices, I assume the three addends are mixed numerals:
3 4/7 + 4 2/9 + 4 3/7 =
= 3 + 4 + 4 + 4/7 + 2/9 + 3/7
= 11 + 7/7 + 2/9
= 11 + 1 + 2/9
= 12 2/9

A boat is carried with the current at an angle of 43 degrees to the shore. if the river is approx. 15 meters wide, how far does the boat travel before reaching the opposite side of the shore
Answer:
22 m
Step-by-step explanation:
The computation of the how much far does the boat travel is as follows:
sin 43 degrees = 15 ÷ d
d = 15 ÷sin 43 degrees
= 15 ÷ 0.6820
= 21.99
= 22 m
Hence, the how much far does the boat travel is 22 m
We simply applied the above formula so that the correct value could come
The same is to be considered

Answer:

Step-by-step explanation:
Let's look at the first option in this multiple-choice; 18. 18 is divisible by 18, but is not divisible by 35, so that answer isn't right.
What about 3? 3 is divisible by 18, but it isn't divisible by 35. Let's move on.
7 is divisible by 35, but it isn't divisible by 18.
1 is universally divisible by anything. That doesn't mean it is the greatest common factor, but in this case it is, because none of the other options are a factor of both numbers given. Therefore, 1 is divisible by 18.
the vertices of parallelogram abcd are A(4,0,3), B(3,4,-2),C(-2,0,1). find the coodrdinates of fourth vertices
Given :
The vertices of parallelogram ABCD are A(4,0,3), B(3,4,-2),C(-2,0,1).
To Find :
The coordinates of fourth vertices.
Solution :
We know, the vertices are ABCD .
Let, point D is (x,y,z) .
Also, diagonals of a parallelogram bisect each other.
Let, point of intersection of daigonal is O.
Coordinates of O are :
[tex]O_x = \dfrac{4+(-2)}{2}= 1\\\\O_y = \dfrac{0+0}{2 } = 0 \\\\O_z = \dfrac{3+1}{2}= 2[/tex]
O(1,0,2)
Value of point O through BD.
[tex]O_x = \dfrac{3+x}{2}\\\\x=-1\\\\O_y = \dfrac{4+y}{2}\\\\y = -4\\\\O_z= \dfrac{-2+z}{2}\\\\z = 6[/tex]
Therefore, the fourth vertices is D( -1,-4,6 ).

Solve the equation.
p over five + 6 = 10
A. 44
B. 30
C. 20
D. –20
p/5 + 6 = 10
=> p/5 = 10-6
=> p/5 = 4
=> p = 5×4
=> p = 20
C. 20
David expressed the ratio of the number of books that he owns to the number of DVDs that he owns as 27:11. Which statement could be true based upon this relationship? David has 11 books and 27 DVDs. David has 11 DVDs and 27 books. David has 11 DVDs and 27 items total. David has 11 books and 27 items total.
Answer: David has 11 DVDs and 27 books.
Step-by-step explanation:
When numbers are put in ratio form they are meant to compare their relative sizes.
The first number will be the first item being compared to the other.
For instance, if you had 2 pens and 3 pencils, the ratio of your pens to your pencils will be; 2:3. The ratio of your pencils to your pens however is 3:2.
In the same vein, a ratio of books to DVDs of 27:11 means that David has 27 books and 11 DVDs.
Answer:
David has 11 DVDs and 27 books.

Answer:
A. (-2, -4)
Step-by-step explanation:
Substitution Method
3x + 2 = -2x - 8
5x = -10
x = -2
y = 3x + 2
y = 3 (-2) + 2
y = -4
(x, y) = (-2, -4)
What were the main important ideas in geometry that you studied in the first six weeks?
Answer:
The preceding chapter explored implications of research on learning for general issues relevant to the design of effective learning environments. We now move to a more detailed exploration of teaching and learning in three disciplines: history, mathematics, and science. We chose these three areas in order to focus on the similarities and differences of disciplines that use different methods of inquiry and analysis. A major goal of our discussion is to explore the knowledge required to teach effectively in a diversity of disciplines.

The equation x^3-3x=1 has a solution between 1.8 and 1.9. use a trial and improvement method to find this solution. give your answer correct to 2 decimal places.
HELPPPPPP I HAVE BEEN TRYING FOR AGES
Answer:
1.88 to 2 decimal places
Step-by-step explanation:
First, I plugged in 1.8 and 1.9:
1.8^3-3*1.8=0.432
1.9^3-3*1.9=1.159
Then, I plugged in 1.85:
1.85^3-3*1.85=0.78
Next, I plugged in 1.87 to get the answer closer to 1:
1.87^3-3*1.87=0.93
Finally, I plugged in 1.88 to get even closer to 1:
1.88^3-3*1.88=1.00
Hope this helps!
Answer:
Step-by-step explanation:
1.8=-0.568 is too small
1.9=0.159 is too big
1.87=-0.70797 is too small
1.88=0.004672 is too big
Next, I plugged in 1.87 to get the answer closer to 1:
1.87^3-3*1.87=0.93
Finally, I plugged in 1.88 to get even closer to 1:
1.88^3-3*1.88=1.00
1.875=-0.033203125 is too small
so it should be 1.88 to 2 decimal places

Can somebody help me with this question, please? I have no idea how to do this or find the answer. :/ How many ways are there to choose a number from the set {−96, −48, −42, −36, −18, −14, −6, 14} that is divisible by either 6 or 8?
Answer:
28 different ways
Step-by-step explanation:
This is a combination question. Combination has to do with selection.
Total number of element in the set = 8
Number divisible by 6 or 8 are {-98, -48, -42, -36, -18, -6}
Total number divisible by 6 or 8 is 6
The number of ways we can choose 6 items from 8 is expressed as;
8C6 = 8!/(8-6)!6!
8C6 = 8!/(2)!6!
8C6 = 8*7*6!/2!6!
8C6 = 8*7/2
8C6 = 56/2
8C6 = 28 ways
Hence there are 28 different ways

In a city the population is increasing exponentially at a rate of 1.6% per year.
Find the overall percentage increase at the end of 20 years.
Answer:
32% increase at the end of 20 years
Step-by-step explanation:
If the population increases at a rate of 1.6% per year, we should multiply it by the number of years that passed, which in this case, is 20. When we multiply those, we get 32%.

HURRY! I HAVE FINALS :(
Answer:
$9.35
Step-by-step explanation:
14.86+25.88+5.76=46.5
55.85-46.5=9.35
Answer:
The rounded number would be nine
Step-by-step explanation:
It would be nine because you convert 55.85 to 56 then convert 14.86 to 15 convert 25.88 to 26 and convert 5.76 to 6 then subtract all of that to get nine hope it helps
