If a hiker starts at sea level and increases her elevation at a rate of 1 foot per minute what will her elevation be in 20 minutes
Answer:
20 feet above sea level.
Explanation:
This can be solved by looking at the Rate of Change. It is given that for ONE minute that passes by, her elevation increases by ONE foot.
With this rate, after 20 minutes, the elevation can be shown as:
20 min × 1 foot= 20 feet.
Answer:
20ft
Step-by-step explanation:
Sea level is at 0 and the hiker hikes for 20 minutes at a rate of 1 foot. 20*1=20.
0+20=20

Allyson has 4.5 pieces of rope to use for a tire swing. If each full piece is 2 2/3 feet long, how much rope does Allyson have in all?
Answer:
12 feet
Step-by-step explanation:
4.5 pieces of rope = 9/2 pieces in fractions
Also, 2 2/3 can be rewritten as 8/3 in fractions
So, 9/2 *8/3 = 72/6 = 12 feet
Allyson has 12 feet of rope in all.

It takes 12.5 mL of a 0.30 M HCl solution to neutralize 285 mL of NaOH solution.
What is the Molarity concentration of the NaOH solution?
13.15 M NaOH
1.5 M NaOH
0.15 M NaOH
0.013 M NaOH
Answer:
0.013 M NaOH
Step-by-step explanation:
HCL + NaOH = NaCL + water
The mole ratio of acid and base is 1:1
Molarity is equal to the moles of solute divided by the liters of solution
Solute mole = 12.5 × 10^-3 × 0.3
= 0.003075
To neutralize 0.00375mol of HCl, 0.00375 mol of NaOH will be required. Since molarity is moles per liter, divide this amount of moles by the volume in liters:
Molarity = 0.00375/285 × 10^-3
Molarity = 0.0131 M
The molarity concentration of the NaOH solution is 0.013M NaOH
The equation of reaction is given as:
[tex]HCl + NaOH >>>>>> NaCl + H_2O[/tex]
Concentration of Hcl, [tex]C_{Hcl}=0.30M[/tex]
Volume of Hcl, [tex]V_{HCl}=12.5mL[/tex]
Concentration of NaOH = [tex]C_{NaOH}[/tex]
Volume of NaOH, [tex]V_NaOH = 285mL[/tex]
From the equation of reaction:
Number of moles of Hcl, [tex]n_{HCl}=1[/tex]
Number of moles of NaOH, [tex]n_{NaOH}=1[/tex]
The formula for neutralization is given as:
[tex]\frac{C_{HCl}V_{HCl}}{C_{NaOH}V_{NaOH}} = \frac{n_{HCl}}{n_{NaOH}}[/tex]
Substitute the values of the parameters
[tex]\frac{0.30(12.5)}{C_{NaOH}(285)} =\frac{1}{1} \\\\C_{NaOH}(285) = 0.30(12.5)\\\\C_{NaOH}(285) = 3.75\\\\C_{NaOH}=\frac{3.75}{285} \\\\C_{NaOH} = 0.013M[/tex]
The molarity concentration of the NaOH solution is 0.013M NaOH

Step-by-step explanation:
A.P.E.X
Yes, being a girl and playing a sport are independent events as P(girl) = P(girl plays a sport) = 0.4

Here, Formula for probability of independent events:
"If A and B are independent events then, P(A∩B) = P(A).P(B)"
And, Formula of the probability of an event A is:
⇒ P(A) = n(A)/n(S)
where, n(A) is the number of favorable outcomes, n(S) is the total number of events in the sample space.
Now, Using the definition of probability:
⇒ P(girl) = Number of girls/ Number of students
⇒ P(girl) = 120/300
⇒ P(girl) = 0.4 .....(1)
And, we find the probability of girls that play a sport.
Using the definition of probability:
P(girl plays a sport) = Number of girls who plays a sport/ number of students who plays a sport
= 70/ 175

The rule is called a "position to term" rule. That means the word "position" is being used to identify the location of a term in the sequence. The first term is in position 1, for example. Using the rule that the position is multiplied by 6, then 10 is subtracted, we find the terms to be as follows.
In position 1, the term is ...
1×6 -10 = -4
In position 2, the term is ...
2×6 -10 = 2
In position 3, the term is ...
3×6 -10 = 8
In position 4, the term is ...
4×6 -10 = 14
In position 5, the term is ...
5×6 -10 = 20
The first 5 terms are -4, 2, 8, 14, 20.

Completing the table of values for the equation
From the question, we have the following parameters that can be used in our computation:
x + y = 6
This can be expressed as
y = 6 - x
The missing y values are at x = 4, 8 and x = 12
Substitute the known values in the above equation, so, we have the following representation
y = 6 - 4 = 2
y = 6 - 8 = -2
y = 6 - 12 = -4
So, the missing values are 2, -2 and 4

Luigi’s Pizza sells an extra‐large pizza with a 40 inch diameter. If the pie is cut into 8 equal slices,what is the area of one slice of Luigi’s pizza?
Answer:
14.1 inches squared.
Step-by-step explanation:
A = (3.141)(6)^2
A = 113.1 inches squared
Now that we know the area, we simply divide it by 8, as there are 8 EQUAL pieces, and so each piece must have an EQUAL area. This gives us:
113.1 / 8 = 14.1

A coin weighs 3/4
ounces. Trey picked up 6 of these coins.
What is the total weight of the coins he picked up?
Write your answer in simplest form.
Answer:
4 2/4
Step-by-step explanation:
3/4 + 3/4 + 3/4 + 3/4 + 3/4 + 3/4
To find the total weight of the coins Trey picked up, multiply the weight of one coin by the number of coins. The total weight is 9/2 ounces or 4.5 ounces in decimal form.
Explanation:To find the total weight of the coins Trey picked up, we need to multiply the weight of one coin by the number of coins picked up. The weight of one coin is 3/4 ounces, and Trey picked up 6 of these coins. To multiply a fraction by a whole number, we multiply the numerator (top number) of the fraction by the whole number. So, the total weight of the coins Trey picked up is (3/4) * 6 = 18/4 ounces.
Next, we simplify the fraction to its simplest form. To do this, we find the greatest common divisor (GCD) of the numerator and denominator, and divide both by the GCD. In this case, the GCD of 18 and 4 is 2. Dividing both the numerator and denominator by 2, we get 18/4 = 9/2. So, the total weight of the coins Trey picked up is 9/2 ounces or 4.5 ounces in decimal form.

There are 5 pennies, 7 nickels, and 9 dimes in an antique coin collection
two coins are to be selected at random from the collection. Find each
10. P(selecting 2 pennies), if no replacement occurs
11. P(selecting 2 pennies), if replacement occurs
12. P(selecting the same coin twice), if no replacement occurs
Answer:
10. 4.8%
11. 5.67%
12. 30.39%
Step-by-step explanation:
The total number of coins is 5 + 7 + 9 = 21 coins
The probability of selecting two pennies without replacemente is:
First penny: 5 possibilities over 21 coins: 5/21
Second penny: 4 possibility over 20 coins: 4/20
P(selecting 2 pennies) = (5/21) * (4/20) = 1/21 = 0.048 = 4.8%
With replacement, we have:
First penny: 5 possibilities over 21 coins: 5/21
Second penny: 5 possibilities over 21 coins: 5/21
P(selecting 2 pennies) = (2/21) * (2/21) = 25/441 = 0.0567 = 5.67%
The cases for selecting the same coin are:
First penny: 5 possibilities over 21 coins: 5/21
Second penny: 4 possibilities over 20 coins: 4/20
P(selecting 2 pennies) = (5/21) * (4/20) = 20/420
First nickel: 7 possibilities over 21 coins: 7/21
Second nickel: 6 possibilities over 20 coins: 6/21
P(selecting 2 nickels) = (7/21) * (6/21) = 42/441
First dime: 9 possibilities over 21 coins: 9/21
Second dime: 8 possibilities over 20 coins: 8/21
P(selecting 2 dimes) = (9/21) * (8/21) = 72/441
P(selecting the same coin twice) = P(selecting 2 pennies) + P(selecting 2 nickels) + P(selecting 2 dimes) = (20+42+72)/441 = 0.3039 = 30.39%
The probabilities for picking 2 pennies either with or without replacement from a total of 21 coins is calculated. With no replacement, the chance is approximately 4.76%, while with replacement, it is approximately 5.67%. It's impossible to choose the same coin twice without replacement.
Explanation:The total number of coins is 5 pennies + 7 nickels + 9 dimes = 21 coins. We are asked to calculate the probability of selecting 2 specific coins from these total coins.
10. P(selecting 2 pennies), if no replacement occurs:
Since no replacement is occurring, we first select one penny out of 5, then another penny out of the remaining 4. That constitutes 5/21 * 4/20 = 0.0476, or 4.76% probability of selecting two pennies without replacement.
11. P(selecting 2 pennies), if replacement occurs:
Since replacement is possible in this scenario, even after choosing a penny, we still have 5 pennies left. Hence, the probability of selecting a penny twice is (5/21) * (5/21) = 0.0567, or approximately 5.67%.
12. P(selecting the same coin twice), if no replacement occurs:
If no replacement occurs, it's impossible to choose the exact same coin twice because once a coin is chosen, it is removed from consideration. Therefore, the probability here is 0.
