Answer:

he needs 9 cans

Step-by-step explanation:

first,

43L/5L

= 8.6 cans

8.6 cans is not logical therefore u need to round up to 9 cans

To determine the correct option, we need to check if the rates and times given in each option satisfy the condition of being inversely proportional.

Option A: 4 mph for 2.25 hours and 6 mph for 1.5 hours.

The product of the rate and time is not consistent: (4 mph) × (2.25 hours) = 9 and (6 mph) × (1.5 hours) = 9. Therefore, this option does not satisfy the condition.

Option B: 6 mph for 1.5 hours and 5 mph for 1.25 hours.

The product of the rate and time is not consistent: (6 mph) × (1.5 hours) = 9 and (5 mph) × (1.25 hours) = 6.25. Therefore, this option does not satisfy the condition.

Option C: 5 mph for 2 hours and 4 mph for 3 hours.

The product of the rate and time is consistent: (5 mph) × (2 hours) = 10 and (4 mph) × (3 hours) = 12. Therefore, this option satisfies the condition.

Option D: 4.5 mph for 3 hours and 6 mph for 4 hours.

The product of the rate and time is consistent: (4.5 mph) × (3 hours) = 13.5 and (6 mph) × (4 hours) = 24. Therefore, this option satisfies the condition.

Answer: c

Step-by-step explanation:

Answer to two decimal places: 34.13%
Approximately 34.13% of college women are between 65 and 68 inches tall.

The empirical rule states that for a normal distribution, approximately 68% of the data falls within one standard deviation of the mean, approximately 95% falls within two standard deviations of the mean, and approximately 99.7% falls within three standard deviations of the mean.
In this case, we are given that the mean height of college women is 65 inches and the standard deviation is 3 inches.
z = (x - μ) / σ
z = (65 - 65) / 3
z = 0

To find the z-score for a height of 68 inches:
z = (x - μ) / σ
z = (68 - 65) / 3
z = 1
Using the standard normal distribution table, we can find that the area between z = 0 and z = 1 is approximately 0.3413.

The, approximately 34.13% of college women are between 65 and 68 inches tall.

Assuming that the size of the stack is constant, we would need to know the number of cans that can be stacked in order to determine the answer. However, let's assume that a single stack can hold 10 cans. If Selene has 90 cans, then we can divide the total number of cans by the number of cans per stack to determine how many stacks are needed.

90 cans / 10 cans per stack = 9 stacks

Therefore, Selene would need 9 stacks to hold all 90 cans. However, there would be some cans left over from the last stack.

9 stacks x 10 cans per stack = 90 cans

The volume of Cylinder #2 is about 157 cm³ greater than the volume of Cylinder.#1 The correct answer is D. 157 cm³.

To compare the volumes of the two cylinders, we will use the formula for the volume of a cylinder, which is V = πr²h, where V is the volume, r is the radius, and h is the height.
Cylinder #1:
Radius (r1) = 5 cm
Height (h1) = 18 cm
Volume of Cylinder #1 (V1) = π × r1² × h1 = π × 5² × 18 = π × 25 × 18 = 450π cm³
Cylinder #2:
Radius (r2) = 5 cm (same as Cylinder #1)
Height (h2) = 20 cm
Volume of Cylinder #2 (V2) = π × r2² × h2 = π × 5² × 20 = π × 25 × 20 = 500π cm³
Now, we will find the difference in volumes:
Difference = V2 - V1 = 500π cm³ - 450π cm³ = 50π cm³ ≈ 157 cm³
So, the volume of Cylinder #2 is about 157 cm³ greater than the volume of Cylinder #1. The correct answer is D. 157 cm³.

In triangle ABC, where A is one of the hooks, B is the other hook, and C is the point where the chains meet:

AC = 1.9 m

BC = 2.2 m

angle BAC = 86°

Find angle BCA, which is the angle of depression that chain AC makes with the ceiling. Use the law of sines to find this angle:

sin BCA / AC = sin BAC / BC

sin BCA = AC sin BAC / BC

sin BCA = 1.9 sin 86° / 2.2

The sprinter's speed before he increased it was 8.2 miles per hour.

To find the sprinter's speed before he increased it, we can use the following steps:
Step 1: Identify the final speed and the increase in speed.
The sprinter's top speed is 23 miles per hour, and he increased his speed by 14.8 miles per hour.
Step 2: Subtract the increase in speed from the final speed.
We can determine the sprinter's initial speed by subtracting the increase in speed (14.8 miles per hour) from the final speed (23 miles per hour).
Initial speed = Final speed - Increase in speed
Initial speed = 23 miles per hour - 14.8 miles per hour
Step 3: Calculate the initial speed.
Now, we can perform the subtraction:
Initial speed = 8.2 miles per hour
So, the sprinter's speed before he increased it was 8.2 miles per hour.

To find the volume of the cube, we need to know the length of one side of the cube. However, since it is not provided in the question, we cannot calculate the exact volume.

We can use a formula to relate the volume of the cube to its surface area. The formula is:

Surface Area = 6 * (side)^2

Given that the surface area of the cube is 294 cm², we can set up the equation:

294 = 6 * (side)^2

Divide both sides of the equation by 6:

49 = (side)^2

Take the square root of both sides:

side = √49

side = 7 cm

Now that we know the length of one side of the cube is 7 cm, we can calculate the volume using the formula:

Volume = side^3

Volume = 7^3

Volume = 343 cm³

Therefore, the volume of the cube is 343 cm³.

Answer:

No you cannot

Step-by-step explanation:

Triangle side length rule says the sum of any two sides must be greater than the remaining side

7 + 8   is NOT greater than 18 ....you cannot draw a triangle with these side lengths

No, we cannot form a triangle using side lengths 7, 8, and 18 units.

The Triangle Inequality Theorem can be used to determine if a triangle can be built with sides that are 7, 8, and 18 units long. The lengths of any two sides of a triangle with side lengths a, b, and c must add up to more than the length of the third side, according to the theorem.

Let's determine if this criterion is satisfied for the specified side lengths:

7 + 8 = 15

7 + 18 = 25

8 + 18 = 26

In this instance, the length of the third side (18) is greater than the total of the two shorter side lengths (7 and 8). This means that a triangle cannot be built using side lengths of 7, 8, and 18 units, according to the Triangle Inequality Theorem.

As a result, with side lengths of 7, 8, and 18 units, a triangle cannot be built according to the Triangle Inequality Theorem.

Answer:

Step-by-step explanation:

Here Is a Quick Explanation :)

To find the axis of symmetry and the vertex of the function, we can use the fact that the function is recursive, and we can write:

f(x) = f(x-1)² + 7

f(x-1) = f(x-2)² + 7

f(x-2) = f(x-3)² + 7

...

f(1) = f(0)² + 7

If we substitute the last equation into the previous one, we get:

f(x-1) = (f(0)² + 7)² + 7

f(x) = ((f(0)² + 7)² + 7)² + 7

This shows that the function depends only on the initial value f(0), and we can use this fact to find the axis of symmetry and the vertex.

To find the axis of symmetry, we need to find the value of x that makes f(x) equal to f(-x). We can write:

f(-x) = f(-(x-1))² + 7 = f(-x+1)² + 7

Now, if we substitute f(x) = f(x-1)² + 7 into the last equation, we get:

f(-x) = (f(x-1)² + 7)² + 7 = f(x)² + 7

This means that the axis of symmetry is the line x = 0, and not y = 7 as stated in option A.

To find the vertex, we need to find the maximum or minimum value of the function. Since f(x) = f(x-1)² + 7, the function is increasing if f(x-1) > -7, and decreasing if f(x-1) < -7. Since f(0) = 7, we can conclude that the function is increasing on the interval -∞ < x < 1, and decreasing on the interval x > 1. Therefore, the vertex is at x = 1, and the corresponding value is f(1) = 7.

Therefore, the correct statements are:

The axis of symmetry of f(x) is x = 0.

The vertex of the function is (1, 7).

f is increasing on the interval -∞ < x < 1.

f is decreasing on the interval x > 1.

Therefore, the probability of drawing exactly 3 aces, 2 queens, and 1 king is approximately 0.000682.

We can solve this problem using the multiplication rule for independent events. The probability of drawing a specific card from a standard deck is 1/52, since there are 52 cards in the deck and each is equally likely to be drawn. We can use this probability to find the probability of drawing a specific combination of cards.

(a) To find the probability of drawing exactly 3 aces, 2 queens, and 1 king, we can break it down into three steps:

Find the probability of drawing exactly 3 aces: There are 4 aces in the deck, so the probability of drawing an ace on the first draw is 4/52. Since we need exactly 3 aces, the probability of drawing 3 aces and 3 non-aces (out of the remaining 48 cards) is given by the binomial probability formula:

P(3 aces) = (4/52)^3 * (48/52)^3 * C(6,3)

where C(6,3) is the number of ways to choose 3 cards out of 6. Using a calculator, we get:

P(3 aces) = 0.0080

Find the probability of drawing exactly 2 queens: There are 4 queens in the deck, so the probability of drawing a queen on the first draw is 4/52. Since we need exactly 2 queens, the probability of drawing 2 queens and 4 non-queens (out of the remaining 48 cards) is given by:

P(2 queens) = (4/52)^2 * (48/52)^4 * C(6,2)

where C(6,2) is the number of ways to choose 2 cards out of 6. Using a calculator, we get:

P(2 queens) = 0.2123

Find the probability of drawing exactly 1 king: There are 4 kings in the deck, so the probability of drawing a king on the first draw is 4/52. Since we need exactly 1 king, the probability of drawing 1 king and 5 non-kings (out of the remaining 48 cards) is given by:

P(1 king) = (4/52)^1 * (48/52)^5 * C(6,1)

where C(6,1) is the number of ways to choose 1 card out of 6. Using a calculator, we get:

P(1 king) = 0.4017

Now we can use the multiplication rule to find the probability of drawing exactly 3 aces, 2 queens, and 1 king:

P(exactly 3 aces, 2 queens, 1 king) = P(3 aces) * P(2 queens) * P(1 king)

= 0.0080 * 0.2123 * 0.4017
