Pam and Tina went for a 12 mile hike (round trip) to the top of a mountain. It took 5 hours. They were able to hike 1 mile per hour faster on the way down. How fast did they hike going up the mountain
Answers
Answer:
2 mph
Step-by-step explanation:
The relationship between time, speed, and distance is ...
time = distance/speed
If s is the speed going up the mountain, then s+1 is the speed coming down. The total trip time for 6 miles up and 6 miles down is ...
6/s +6/(s+1) = 5
6(s+1) +6s = 5(s)(s+1)
5s^2 -7x -6 = 0 . . . . subtract the left side, simplify to standard form
(s -2)(5s +3) = 0 . . . . factor
s = 2 or -3/5 . . . . values that make the factors 0
Their speed was 2 miles per hour going up the mountain.

A company produced in the first quarter 6,905 pieces in the second quarter the same company produced 795 pieces more than in the first quarter under these conditions how many pieces did the company produce in the first semester?
Answers
Answer: 14,605 pieces.
Step-by-step explanation:
In the second quarter, the company produced 795 pieces more than in the first quarter.
So, the total pieces produced in the second quarter can be calculated as:
6905 + 795 = 7700
The total pieces produced in the first semester (two quarters) can be calculated as:
6905 + 7700 = 14,605
Therefore, the company produced 14,605 pieces in the first semester.
The number of pieces the company produced in the first semester was 14,605 pieces.
How many?The question asks to calculate how many pieces a company produced in the first semester, considering the production of two quarters.
In the first quarter, the company produced 6,905 pieces, as indicated in the question.
Already in the second quarter, the company produced 795 more pieces than in the first quarter, which means that the production in the second quarter was:
6,905 + 795 = 7,700 pieces.
To know the company's total production in the first semester, just add the productions of the two quarters:
6,905 + 7,700 = 14,605 pieces

You plan to glue the pieces together and then outline each piece withblack cord.a. How much black cord does the design use?b. How much fabric of each color does the design show?c. At a craft store, fabric comes in bolts that are a fixed number of inches wide.You can only buy fabric by the whole yard. If each bolt is 48 in. wide, what isthe least amount of each color that you need to buy? Explain.please I try to solve it but I did not understand it please need help thank you so much.
Answers
To know the total amount of fabric we need per color, we need to find the area of each color.
The green rectangle.\(A_{green}=16\cdot10=160ft^2\)The blue square.\(A_{blue}=7\cdot7=49ft^2\)The orange triangles.\(A_{orange}=4(\frac{1}{2}\cdot1.75\cdot2)=\frac{14}{2}=7ft^2\)The yellow circle.\(A_{circle}=\pi r^2=3.14\cdot(1.5)^2=3.14\cdot2.25=7.065ft^2\)Now, the bolts are sold in fixed yards, we know that 48 inches are equivalent to 1.333... yards, or 4 feet. But, we are using areas so, 48 to the square power in square inches would be equivalent to 16 square feet.
Then, we divide each area by 16 square feet.
\(b_{green}=\frac{160}{16}=10\)We need 10 bolts of green fabric.
\(b_{blue}=\frac{49}{16}=3.0625\)We need 4 bolts of fabric since if we use 3 we would need a bit more.
\(b_{orange}=\frac{7}{16}=0.4375\)We just need 1 bolt of orange fabric.
\(b_{yellow}=\frac{7.065}{16}=0.44\)We need 1 bolt of yellow.

A student ran a distance of 3 1/2miles each day for 5 days. Then the student ran a distance of 4 1/4 miles each day for the next 5 days. What was the total distance in miles the student ran during these 10 days?
Answers
Answer:
To find the total distance, we need to add up the distance the student ran in the first 5 days and the distance the student ran in the next 5 days.
Distance for the first 5 days = 3 1/2 miles/day × 5 days = 17.5 miles
Distance for the next 5 days = 4 1/4 miles/day × 5 days = 21.25 miles
Total distance = Distance for the first 5 days + Distance for the next 5 days
Total distance = 17.5 miles + 21.25 miles
Total distance = 38.75 miles
Therefore, the student ran a total of 38.75 miles during these 10 days.

The solution that can be used to fill in location A is 45%.
In this case, Rena is trying to make a 45% solution. The alligation diagram shows two solutions with concentrations of 20% and 45%. The concentration at location A represents the concentration of the final mixture.
To determine the concentration at location A, we can visually observe the positioning of the concentrations on the diagram. The closer a concentration is to location A, the more it contributes to the final mixture.
In this case, the concentration of 45% is closer to location A than the concentration of 20%.
This means that more of the 45% solution should be used in the mixture to achieve a 45% concentration.
Therefore, the solution that can be used to fill in location A is 45%.

The rat population in a major metropolitan city is given by the formula n(t)=89e^0.02t where t is measured in years since 1992 and n(t) is measured in millions
What was the rat population in 1992?
What does the model predict the rat population was in the year 2003?
Answers
Answer:
See below ~
Step-by-step explanation:
What was the rat population in 1992?⇒ t represents the years after 1992
⇒ So, in 1992, t = 0
⇒ Apply in the formula
⇒ n(0) = 89e^(0.02 × 0)
⇒ n(0) = 89e⁰
⇒ n(0) = 89,000,000
The rat population in 1992 was 89,000,000.
===========================================================
What does the model predict the rat population was in the year 2003?⇒ Number of years after 1992 : 2003 - 1992 = 11
⇒ Substitute for t in the formula
⇒ n(11) = 89e^(0.02 × 11)
⇒ n(11) = 89e^(0.22)
⇒ n(11) = 89 × 1.24607673
⇒ n(11) = 110,900,829 rats
The model predicts that in the year 2003 there will be a rat population of 110,900,829 rats.
Answer:
(a) 89,000,000 rats
(b) 110,900,829 rats
Explanation:
Given equation:
n(t)=89e^0.02tTo find the initial population (1992):
insert t = 0
n(0) = 89e^0.02(0) = 89 million ≈ 89,000,000To find the rat population in 2003 (after 11 years):

hay 1230 personas, entre hombres y mujeres. Si se sabe que el número de mujeres, supera en 150 al número de hombres. ¿Cuántos hombres están habitando la mini ciudad?
Answers
There are 540 men living in the mini city.
x + (x + 150) = 1230
Simplifying this equation, we get:
2x + 150 = 1230
Subtracting 150 from both sides, we get:
2x = 1080
Dividing both sides by 2, we get:
x = 540
Therefore, there are 540 men living in the mini city.
To check our answer, we can substitute x = 540 into our original equation:
540 + (540 + 150) = 1230
690 = 1230
This is false, so there must be an error in our calculation. We can double-check our work by trying a different approach.
We know that the number of women exceeds the number of men by 150, so we can represent the number of women as (x + 150). We also know that the total number of people is 1230, so we can set up an equation:
x + (x + 150) = 1230
Simplifying this equation, we get:
2x + 150 = 1230
Subtracting 150 from both sides, we get:
2x = 1080
Dividing both sides by 2, we get:
x = 540
