The distance between the candy store and the skate park is about 5.2 miles, with a hypotenuse of 6 miles and a leg of 9 miles, as computed using the Pythagorean theorem.
The candy shop is at the right angle of a triangle made up of Cindy's school, the skate park, and the candy store. Using the Pythagorean theorem, we can calculate the distance between the skate park and the candy shop.
Let's name the separation between the candy shop and the skate park "x" distance. The hypotenuse of the right triangle, the distance between Cindy's school and the candy store, is then 6 miles away, while one of the legs, the skate park, is 9 miles away.
Using the Pythagorean theorem, we can write:
6² = 9² + x²
Simplifying, we get:
x² = 27
Taking the square root of both sides, we get:
x ≈ 5.2
Therefore, The distance between the candy store and the skate park is about 5.2 miles, with a hypotenuse of 6 miles and a leg of 9 miles, as computed using the Pythagorean theorem.

A shaded semicircle is inside a circle
The radius of the circle is 10 cm
The diameter of the semicircle is 8 cm
How many times bigger is the unshaded area than the shaded area?
The unshaded area is 11.5 times bigger than the shaded area.
What is the area of the circle?
The area of the circle is given by:
A_circle = πr^2
where;
r is the radius of the circle. In this case, r = 10 cm, so:
A_circle = π(10 cm)^2 = 100π cm^2
The area of the semicircle is given by:
A_semicircle = (1/2)πr^2
where;
r is the radius of the semicircle.In this case, the diameter of the semicircle is 8 cm, so the radius is 4 cm:
A_semicircle = (1/2)π(4 cm)^2 = 8π cm^2
To find the area of the shaded region, we need to subtract the area of the semicircle from the area of the circle:
A_shaded = A_circle - A_semicircle
= 100π cm^2 - 8π cm^2
= 92π cm^2
The unshaded area is the area of the circle minus the area of the shaded region:
A_unshaded = A_circle - A_shaded
= 100π cm^2 - 92π cm^2
= 8π cm^2
So the unshaded area is 8π cm^2 and the shaded area is 92π cm^2.

Find the inequality represented by the
graph.
Answer:
Based on these observations, the inequality represented by the graph is y > mx + b, where m is a positive number and b is a negative number.
Step-by-step explanation:
The graph represents a linear function. To find the inequality, we can find the equation of the line in slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept.
From the graph, it can be seen that the slope of the line is positive, which means that as x increases, y also increases. Also, the y-intercept is negative, which means that the line crosses the y-axis at a negative value.
Based on these observations, the inequality represented by the graph is y > mx + b, where m is a positive number and b is a negative number.
Note that the exact values of m and b can be found by using two points on the line and solving for the slope and y-intercept using the formula for a line.

If radius of circle is tripled then area of circle will be increased by
If radius of circle is tripled then area of circle will be increased by:9 times.
If the radius of a circle is tripled, then the new radius is three times the original radius, or R' = 3R, where R is the original radius and R' is the new radius. The area of a circle is given by the formula A = πR^2, where A is the area and R is the radius.
Substituting R' = 3R into the formula for the area of a circle, we get:
A' = πR'^2

the cost to rent a car from lou's garage is 50 + 0.1m dollars for m miles. The cost of a car ar Jerry's Garage is 25 + 0.05m dollars for the same number of miles
Answer:
To find out which rental car company is cheaper, you need to compare the cost for the same number of miles driven. Let's say you drive a total of "m" miles.
The cost for renting a car from Lou's Garage is 50 + 0.1m dollars.
The cost for renting a car from Jerry's Garage is 25 + 0.05m dollars.
To determine which option is cheaper, you need to compare these two expressions and find out which one is less. To do this, you can subtract the second expression from the first expression:
50 + 0.1m - (25 + 0.05m) = 25 + 0.05m
This equation shows that the cost of renting a car from Lou's Garage is 25 + 0.05m dollars more expensive than renting a car from Jerry's Garage for the same number of miles driven. Therefore, Jerry's Garage is the cheaper option.

To solve the inequality 3x - 1 <= -7, we can start by adding 1 to both sides to isolate the variable:
3x - 1 + 1 <= -7 + 1
Simplifying, we get:
3x <= -6
Next, we can divide both sides by 3 to solve for x:
3x/3 <= -6/3
Simplifying, we get:
x <= -2
This tells us that any value of x that is less than or equal to -2 will make the inequality true. We can represent this on a number line by shading all values less than or equal to -2
The circle at -2 indicates that -2 is included in the solution set, and the arrow pointing to the left indicates that all values less than -2 are also included in the solution set. Therefore, the number line that shows all of the values of x that make the inequality 3x - 1 <= -7 true is the one with all values less than or equal to -2 shaded.

Double spin is a new game the player gets to spin a spinner twice but wins only if the same amount comes up both times. The $100 sector is 1/8 of the circle.
a. What is the expected value when playing this game if you can play the game for free?
c. If it costs $3. 00 for you to play this game, should you expect to break even in the long run?
a. If you can play the game for free, the expected value is zero since there is no cost and no prize for winning.
How to calculate breaking even?b. To calculate the expected value when it costs $3 to play, we need to first find the probability of winning.
There are 8 possible outcomes on the spinner, and only one of them results in a win, so the probability of winning is 1/8. The probability of losing is 7/8.
The expected value is the sum of the product of each outcome and its probability. Let X be the amount won. Then:
E(X) = (1/8)($100) + (7/8)(-$3)
= $12.50 - $2.63
= $9.87
So the expected value when it costs $3 to play is $9.87. Since the expected value is positive, you can expect to make a profit in the long run.
However, this does not mean that you will win every time you play, as the outcome of each individual game is still random.

A hybrid car with a 9. 80 gal tank consumes gasoline at a rate of 54. 1 miles/gal. How many liters of gasoline will be consumed traveling 132 km?
The hybrid car will consume approximately 21.65 liters of gasoline to travel 132 km.To convert the hybrid car's fuel consumption rate from miles/gallon to kilometers/liter, we need to multiply by a conversion factor of 0.425 (1 mile = 1.609 kilometers, 1 gallon = 3.785 liters).
So the car's fuel consumption rate is 54.1 miles/gallon x 0.425 km/mile ÷ 3.785 liters/gallon = 6.09 km/liter.To find how many liters of gasoline the car will consume traveling 132 km, we can use the formula:
Gasoline consumed = distance traveled ÷ fuel consumption rate
Gasoline consumed = 132 km ÷ 6.09 km/liter = 21.65 liters (rounded to two decimal places).Therefore, the hybrid car will consume approximately 21.65 liters of gasoline to travel 132 km.
