It says that raise school is 1. 7 miles from his house the student walks 17 miles in a 5-day school week
If the school is 1.7 miles from the student's house, then the round trip distance between the house and school is 2 times 1.7 miles, or 3.4 miles per day.
A mile is defined as the unit of length, which is exactly equal to 5280 feet, or 1760 yards, and standardized as exactly 1609.344 meters by the International agreement in 1959. It is the largest unit that is commonly used to measure the distance between places that are far from each other.
To find out how many miles the student walks in a 5-day school week, we can multiply the daily distance by the number of school days in a week:
3.4 miles/day x 5 days/week = 17 miles/week

How to find the semicircle and quarter circle.
# Distance and No. of turns.
Answer:
A semicircle can be drawn by first drawing a diameter of a circle, which is a line segment connecting two points on the circumference that passes through the center of the circle. Then, the semicircle can be constructed by drawing an arc that is half of the circumference of the circle and connecting the ends of the arc to the endpoints of the diameter.
A quarter circle can be drawn in a similar way, but instead of drawing an arc that is half of the circumference, you would draw an arc that is a quarter of the circumference. To do this, you would need to find the central angle that subtends the arc and divide it by 4. The quarter circle can then be constructed by drawing an arc with this central angle and connecting the ends of the arc to the endpoints of a radius of the circle, rather than the diameter.
In both cases, you can use a compass or a protractor to accurately draw the arcs.

54 is what percent of 200?
PLEASE GIVE BRAINLIEST!
thank you and have a good day :)
Answer:
27%
Step-by-step explanation:
a percent is a part of 100
so if we get the denominator to 100, the numerator is the percent of the equation
54/200
in order to get 200 to 100, we have to divide by 2.
however we have to divide the numerator aswell as if we don't, we simply just half the equation.
54/2 = 27
200/2 = 100
27/100 is the new equation. referring back to the first statement, i made, the numerator would be the percent of the equation that is a part of 100
27%.
54/200 is equal to 27/100. all we did was divide both the numerator and denominator by 2.

Triangle QRS triangle TUV.

R
S
What is the measure of LQ and the measure of LS?
U
T
Answer: Since triangle QRS and triangle TUV are both triangles, we can use the fact that the sum of the interior angles in a triangle is 180 degrees.
In triangle QRS, the measure of angle Q is 117 degrees and the measure of angle R is 180 - 117 = 63 degrees. The measure of angle S is 180 - 63 = 117 degrees, since the angles in a triangle add up to 180 degrees.
In triangle TUV, the measure of angle T is 180 - 30 = 150 degrees and the measure of angle U is 30 degrees. The measure of angle V is 180 - 150 = 30 degrees, since the angles in a triangle add up to 180 degrees.
The measures of LQ and LS can be found using the fact that the exterior angle of a triangle is equal to the sum of the measures of the two interior angles that are not adjacent to it.
The measure of LQ is equal to the sum of the measures of angles R and T:
LQ = 63 + 150 = 213 degrees
The measure of LS is equal to the sum of the measures of angles Q and U:
LS = 117 + 30 = 147 degrees
So the measure of LQ is 213 degrees and the measure of LS is 147 degrees.

out of the 10,000 people who took their driving test for the first time, it was found that 6500 passed the test on the first attempt. estimate the probability that a randomly selected person would pass the driving test on the first attempt.
To estimate the probability that a randomly selected person would pass the driving test on the first attempt, we can divide the number of people who passed on the first attempt (6500) by the total number of people who took the test (10,000).
Probability = Number of favorable outcomes / Total number of possible outcomes.In this case, the favorable outcome is passing the test on the first attempt, and the possible outcomes are all the people who took the test.
Probability = 6500 / 10000= 0.65
Therefore, the estimated probability that a randomly selected person would pass the driving test on the first attempt is 0.65 or 65%. This means that there is a 65% chance that a randomly selected person from the group of 10,000 would pass the driving test on their first try.

Lin and Andre start walking toward each other at the same time from opposite ends of the 22-mile walking trail. Lin walks at a speed of 2. 5 miles per hour. Andre walks at a speed of 3 miles per hour. How long will it take until Lin and Andre meet on the path?
If Lin walks at a speed of 2. 5 miles per hour. Andre walks at a speed of 3 miles per hour. It will take 4 hours until Lin and Andre meet on the path.
Lin and Andre are walking toward each other on a 22-mile trail, so they will meet when the sum of the distances they have walked is equal to 22 miles. Let's call the time they walk until they meet "t".
During this time, Lin will have walked a distance of 2.5t miles, and Andre will have walked a distance of 3t miles. The sum of these distances is equal to 22 miles, so we can set up the equation:
2.5t + 3t = 22
Combining like terms, we get:
5.5t = 22
Dividing both sides by 5.5, we get:
t = 4
So it will take Lin and Andre 4 hours to meet on the path.
Note that we could have also solved this problem by using the formula:
time = distance / speed
For Lin, the time to cover the 22-mile distance would be:
time = distance / speed = 22 / 2.5 = 8.8 hours
For Andre, the time to cover the 22-mile distance would be:
time = distance / speed = 22 / 3 = 7.33 hours
Since they are walking towards each other, we can add their times to get the time it takes for them to meet:
time = 8.8 + 7.33 = 16.13 hours
However, we can see that this answer is not correct, as it is greater than the time it would take for either of them to cover the entire distance. This is because the time it takes for them to meet is less than the sum of their individual travel times, due to them moving towards each other.
So we go back to our original equation and solve for "t" to get the correct answer of 4 hours.

The area of the trapezoid would be 42.5 m².
What is the area of a trapezoid?
The area of a trapezoid is given by the formula:
Area = (1/2) × (sum of the bases) × height
where the bases are the two parallel sides of the trapezoid and the height is the perpendicular distance between the bases.
The parameters of the trapezoid are;
Short base length = 3 m
Height = 5
Large base length = 4 + 3 + 7 = 14 m
Thus;
Area of a trapezoid = 1/2 * (Short base + Large base) * h
Area = 1/2 * (3 + 14) * 5
= 1/2 * 17 * 5
= 42.5 m²

Chandra just spends 15 minutes away or math problems she spends the same amount of time on each problem how many minutes does she spend on each problem
Chandra spends 3 minutes on each math problem if she spends a total of 15 minutes on math problems and spends the same amount of time on each problem
Chandra spends the same amount of time on each math problem. Let's call the amount of time she spends on each problem "t".
We know that Chandra spends a total of 15 minutes on math problems. If she spends the same amount of time on each problem, then the total time spent on all the problems is equal to the number of problems multiplied by the time spent on each problem.
So, we can write the following equation:
total time spent on all problems = number of problems * time spent on each problem
We know that the total time spent on all problems is 15 minutes, so we can substitute this into the equation:
15 = number of problems * t
We don't know the number of problems, but we can solve for t by rearranging the equation:
t = 15 / number of problems
So, the amount of time Chandra spends on each math problem is equal to 15 divided by the number of problems.
For example, if Chandra works on 5 math problems, then the amount of time she spends on each problem is:
t = 15 / 5 = 3
So, Chandra spends 3 minutes on each math problem if she spends a total of 15 minutes on math problems and spends the same amount of time on each problem.

The time taken by population of bacteria to be doubled whose normal growth is six fold in 10 hours is equal to 3.87 hours.
Let us consider 'n' is the time taken by the bacteria populations.
And P(n) represents the population of the bacteria in time 'n'
Using exponential growth function we know,
P(n) = K e^(a× n)
Where K and 'a' are the constants.
From the given condition we have :
P(10 ) = 6 P(0)
⇒ K e^ (10a) = 6k e^(0 × a )
⇒ e^(10a) = 6
⇒ 10a = log 6
⇒ a = ( log 6 ) / 10
Now required time when population is double :
P(n ) = 2P(0)
⇒ K e^ (n × a) = 2k e^(0 × a )
⇒ e^ [ n ×( log 6 ) / 10 ] = 2
⇒ n ×( log 6 ) / 10 = log 2
⇒ n = ( 10 × log 2 ) / log 6
⇒ n = ( 10 × 0.3010 ) / 0.7782
