To find out how much time the campers took to get downstream, we can use the formula:
time = distance / speed
where distance is the distance they paddled downstream (in this case, 2 km) and speed is their average speed (in this case, 12 km/h). So we can substitute in the values we know to get:
time = 2 km / 12 km/h
To solve for the time, we can divide the distance by the speed:
time = 2/12 hours = 0.17 hours or approximately 10.2 minutes
So it takes 10.2 minutes for Nick and Chloe to get downstream.
Can you explain this too me please?
The situation regarding the experimental probability is described as follows:
The probability that she makes a shot is of 62.5% = 5/8. Use whole numbers from 1 to 8, with 1-5 representing shots that she makes, and 6-8 representing the shots that she misses. For each trial, generate 10 random numbers. Count the number of trials in which the numbers 1 - 5 appears 3 or more times. Divide the number of trials in which she made at least 3 shots by the total number of trials.
How to obtain a probability?A probability is calculated as the division of the number of desired outcomes by the number of total outcomes.
The theoretical probability of making a shot in this problem is given as follows:
62.5%.
The equivalent fraction is given as follows:
5/8.
Hence, to obtain the experimental probability, we need to design an experiment for which there are eight possibilites, with five of them composing a success and three of them composing a failure.

Malik uses an app on his phone to track how far he rides his bike. Yesterday, he biked a new trail in a total of 57.5 minutes, including a 2.5-minute water break. The app notified Malik that he rode 10 miles. What was Malik's average pace while biking?
The average pace of Malik is 0.182 mile per minute.
What is Speed?Speed is the unit rate in terms of distance travelled by an object and the time taken to travel the distance.
Speed is a scalar quantity as it only has magnitude and no direction.
Given that,
Distance Malik rode on a trail = 10 miles
Malik biked a new trail in a total of 57.5 minutes.
But he took 2.5 minutes as water break.
Total time Malik took to cover the distance = 57.5 minutes - 2.5 minutes
= 55 minutes
We have to calculate the average pace of Malik which is actually the speed.
Speed = Distance / Time
= 10 miles / 55 minutes
= 0.182 mile per minute
Hence Malik rides in an average pace of 0.182 mile per minute.

carp | salmon
---------------------
lake a | 15 | 48
lake b| 35 | 7
lake c | 9 | 30
The ratio of carp to salmon for each lake is given as follows:
Lake a: 1 : 3.2.Lake b: 1 : 0.2.Lake c: 1: 3.33.
Then the ascending order on the proportion of fish that are salmon is given as follows:
Lake b, Lake c, Lake c.
How to obtain the ratios?The ratio of an amount A over an amount B is obtained applying the proportion of these amounts, that is, the division of A by B.
The ratios of carp to salmon, in the form 1:n, are obtained considering that n is the division of the number of salmon by the number of carp, hence:
Lake a: n = 48/15 = 3.2.Lake b: n = 7/35 = 0.2.Lake c: n = 30/9 = 3.33.The higher rates of salmon have the higher values of n, thus the ascending order of the proportion of fish that are salmon is given as follows:

Answer:
IF tan(theta) = -8/7 = opposite side/adjacent side, then that means that sin(theta) = -8/(sqr(64+49) = -8/sqr113 = about -0.7526
Step-by-step explanation:
the tangents are negative in the quadrant II or IV
and sines are negative in the quadrant III or IV
so i think that this angle is in quadrant IV to satisfy for the of the both requirements.
but angle 0 seems to try and mean something other than 0 degrees or 0 radians. so It probably just means theta, which is a 0 probably with a line through it
IF tan(theta) = -8/7 = opposite side/adjacent side, then sin(theta) = -8/(sqr(64+49) = -8/sqr113 = about -0.7526

ABC and XYZ are similar. Find the missing side length.
Hello there!
∆ABC and ∆XYZ are simular so:
[tex] \displaystyle \frac{AB}{XY} = \frac{BC}{YZ} = \frac{AC}{XZ} \\ \\ \frac{2}{10} = \frac{5}{25} = \frac{AC}{20} \\ \\ \frac{1}{5} = \frac{1}{5} = \frac{AC}{20} \\ \\ \frac{AC}{20} = \frac{1}{5} \\ \\ AC = \frac{20 \times 1}{5} = 4[/tex]
Answer: 4
Answer:
4
Step-by-step explanation:
We have to find length of AC in ΔABC
Since ΔABC is similar to ΔXYZ, the corresponding sides of ΔABC to the corresponding sides of ΔXYZ should be of similar ratio
Equivalently stated
[tex]\dfrac{AB}{XY} = \dfrac{BC}{YZ} = \dfrac{AC}{XZ}[/tex]
Plugging in known values we get
[tex]\dfrac{AB}{XY} = \dfrac{2}{10} = \dfrac{1}{5}\\\\\dfrac{BC}{YZ} = \dfrac{5}{25} = \dfrac{1}{5}\\[/tex]
Thus we see that the length of each side of ΔABC is one-fifth the length of each corresponding side of ΔXYZ.
So
[tex]AC =\dfrac{1}{5} XZ = \dfrac{1}{5} \cdot 20 = 4[/tex]

How do you tell if a graph is exponential growth or decay?
To tell if a log graph is a growth or decaying, look at the slope of the line. If the slope is positive, then it is growth; if the slope is negative, then it is decay.
A positive slope indicates that the value is increasing over time, while a negative slope indicates that the value is decreasing over time. To find the slope, take two points on the line and calculate the change in the y-value divided by the change in the x-value.
If the answer is positive, the graph is growth; if the answer is negative, the graph is decay. Additionally, you can look at the y-intercept of the graph, which is the value where the line meets the y-axis. If the y-intercept is positive, the graph is growth; if the y-intercept is negative, the graph is decay.

The original price of the blender before the discount is $49.41.
How to calculate the original price of the blenderWe shall represent the original price of the blender with the letter x so that we use $x to evaluate for the original price before the discount price as follows:
x - 15x/100 = $42 {simply the left hand expression to a single fraction}
(100x - 15x)/100 = $42 {simply the terms in the bracket}
$85x/100 = $42
$85x = $4200 {cross multiplication}
$85x/$85 = $4200/$85 {divide through by $85}
x = $49.41

On a necklace of 150 beads 75 beads are glass and 78 are ceramic what percent of beads are glass
Answer:
Doesn't make sense but with the information given. To find the percentage of glass beads on the necklace, you need to divide the number of glass beads by the total number of beads and multiply by 100.
You can use the formula:
percent = (number of glass beads / total number of beads) x 100
In this case:
percent = (75 / 150) x 100 = 0.5 x 100 = 50
So, 50% of the beads on the necklace are glass.

when f(x) = 6x² - 2x - 5, evaluate f(-2)
Answer:
23
Step-by-step explanation:
Given Information:
f(x) = 6x² - 2x - 5If we have to evaluate f(-2), we can consider that f(x) = f(-2) = 6x²- 2x - 5.
So, if f(x) = f(-2), then we have the following solution: x = -2.Now, we can substitute the solution into the quadratic equation and simplify it to its simplest possible form using the solution (x = -2).
⇒ f(-2) = 6x² - 2x - 5 ⇒ f(-2) = 6(-2)² - 2(-2) - 5 ⇒ f(-2) = 6(-2)(-2) - 2(-2) - 5 ⇒ f(-2) = 6(4) + 2(2) - 5 ⇒ f(-2) = 24 + 4 - 5 ⇒ f(-2) = 24 - 1 = 23Therefore, the evaluated form for f(-2) is 23.
Does scientific notation have to be greater than 1?
The mantissa of scientific notation is between 1 and 10 in absolute value, or 1 ≤ |a| < 10. It can be 1, hence, it does not have to be greater than 1.
A scientific notation has the form:
a x 10ᵇ
Where b is an integer and is called exponent.
a is a real number between 1 and 10 (in absolute value), it includes 1 but not 10, or we can write a should satisfy 1 ≤ |a| < 10.
Usually, a is called mantissa.
Example:
2567 can be written in scientific notation as:
2567 = 2.567 x 10³
0.0045 can be written in scientific notation as:
0.0045 = 4.5 x 10⁻³
250 x 10² can be written in scientific notation as:
250 x 10² = 2.5 x 10⁴

Which polynomial should be added in 3x³ 2x² +3 to get the polynomial 3x² +4?(1) 3x3 + 5x2 +1 (2) 3x2 – 5x +1 (3) - 3x3 + 5x2 +1 (4) - 3x3 - 5x2 + 1Answer with explanation
The polynomial 3x³ 2x² +3 can be written as 3x³ + 2x² + 3. In order to get the polynomial 3x² + 4, we need to add a polynomial which is equal to -3x³ + 5x² + 1.
Therefore, the correct answer is (3) - 3x3 + 5x2 +1.
We can confirm this by performing the following calculation:
3x³ + 2x² + 3 + (-3x³ + 5x² + 1) = 3x² + 4
3x³ + (-3x³) = 0
2x² + 5x² = 7x²
3 + 1 = 4
Therefore, 0 + 7x² + 4 = 3x² + 4, which confirms that the correct answer is 3x3 + 5x2 +1.
