which statement is true about quadrilateral QRST

Answer: 1000

Step-by-step explanation:

If one person can pick up a plate every 10 seconds, then the rate of picking up plates can be represented as 1 plate/10 seconds.

When two people are picking up plates, the rate doubles, so it becomes 2 plates/10 seconds or 1 plate/5 seconds.

To find how long it will take for 200 people to pick up plates, we need to use the formula:

time = amount ÷ rate

Plugging in the values, we get:

time = 200 plates ÷ (1 plate/5 seconds)

time = 200 plates × 5 seconds/plate

time = 1000 seconds

Therefore, it will take 1000 seconds for 200 people to pick up plates at a faster rate.

Answer: (C) 1/3

Step-by-step explanation:

Look at the base lengths. For A'B'C', the length is 2. For ABC, it is 6. The ratio of the length of A'B'C' to the length of ABC is 1/3. Thus the answer is C.

The cross-sectional area of the cylinder with a base diameter of 44cm is approximately 1520.5 cm².

A cylinder is simply a 3-dimensional shape having two parallel circular bases joined by a curved surface.

The cross-sectional area of a cylinder is expressed as;

Cross-sectional area A = πr²

From the diagram:

The dameter of the base of the base of the cylinder is 44cm.

We can determine the radius by dividing the diameter by 2:

Radius r = 44 cm / 2

Radius r = 22 cm

Now, plug the value of the radius into the formula to find the cross-sectional area:

Cross-sectional area A = πr²

Cross-sectional area A = π(22 cm)²

Cross-sectional area A = 484π cm²

Cross-sectional area = 1520.5 cm²

Therefore, the cross-sectional area is approximately 1520.5 cm².

Lets take a look at example one attached image:

The constant of proportionality is the value of y when x = 1 in a proportional relationship.

On which line does y = 1/2 when x = 1?

Only line C has a y- value less than 1 when x = 1, but how can we be sure that the constant of proportionality is exactly 1/2?

If the constant of proportionality of a proportional relationship is 1/2 then:

y = 1/2x (like rise over run (slope), rise up 1 unit, and run right 2 units)

We can try the point (2, 1), and plug in the values into the equation, where x = 2, y = 1.

(1) = 1/2(2)

1 = 1

Line C has a constant proportionality of 1/2 between x and y.

Step-by-step explanation:

It will cost $1080 to paint all the interior surfaces of the pool.

6. & 7. The triangles have sides of 8, 8, and 10 cm, and an area of 24 square cm. The remaining areas are 18 and 12 square cm, respectively.

Triangle with Sides 8, 8, and 10 cm: First, we must calculate the area of the whole triangle, which has sides of 8, 8, and 10 cm. Using the Heron's formula, we can find the area of a triangle given the lengths of its sides: A = √(s(s - a)(s - b)(s - c)), where s = (a + b + c)/2 is the semi perimeter of the triangle.

A = √(13(13 - 8)(13 - 8)(13 - 10)) = √(13(5)(5)(3)) = √(2925) = 15√(65) ≈ 59.17 square cm. Next, we can calculate the areas of the shaded regions as follows: Area of Shaded Region 1 = Area of Whole Triangle - Area of Small Triangle Area of Shaded Region 1 = 15√(65) - 18 = 15√(65) - 6√(65) = 9√(65) ≈ 27.94 square cm.

Area of Shaded Region 2 = Area of Whole Triangle - Area of Large Triangle Area of Shaded Region 2 = 15√(65) - 24 = 3√(65) ≈ 7.74 square cm.7.

A swimming pool has the dimensions 8 m (length), 6 m (width), and 1.5 m (depth). The total area to be painted is the sum of the areas of the floor, the ceiling, and the walls of the pool. Since the pool is rectangular in shape, we can break it down into six different parts: the top and bottom surfaces, and the four vertical surfaces.

Let's begin by calculating the area of the floor, which has dimensions of 8 m by 6 m:Area of Floor = length x width = 8 x 6 = 48 square meters.

Next, we can calculate the area of the ceiling, which has the same dimensions as the floor: Area of Ceiling = length x width = 48 square meters. Since the pool has a depth of 1.5 m, the total height of the vertical surfaces is 1.5 x 2 = 3 m (since there are two vertical surfaces on each side of the pool).

Thus, the total area of the four vertical surfaces is given by: Area of Walls = perimeter x height = 2(length + width) x height = 2(8 + 6) x 3 = 84 square meters.

Finally, we can calculate the total area to be painted by adding up the area of the floor, ceiling, and walls: Total Area = Area of Floor + Area of Ceiling + Area of Walls Total Area = 48 + 48 + 84 = 180 square meters.

The cost of paint is given as $6 per square meter, so we can calculate the total cost of painting the pool as follows: Cost = Total Area x Cost per Square Meter Cost = 180 x $6 = $1080. Therefore, it will cost $1080 to paint all the interior surfaces of the pool.

The probability is 5/8 that the second number chosen will exceed the first number by a distance greater than 1/4 unit on the number line when two numbers are randomly chosen between 0 and 1.

To determine the probability that the second number chosen will exceed the first number by a distance greater than 1/4 unit on the number line, we need to consider the possible range of values for both numbers.

Since the two numbers are chosen randomly between 0 and 1, we can visualize this as a unit interval on the number line, where 0 represents the left endpoint and 1 represents the right endpoint.

Let's analyze the scenario where the first number is chosen and labeled as x. The probability that the second number chosen will exceed x by a distance greater than 1/4 unit can be represented by the shaded area on the number line.

To calculate this probability, we need to determine the length of the interval where the second number can be chosen, given that it exceeds x by more than 1/4 unit.

If the first number, x, is chosen between 0 and 3/4 (i.e., x < 3/4), the second number can be chosen in the range (x + 1/4, 1]. The length of this interval is 1 - (x + 1/4) = 3/4 - x.

If the first number, x, is chosen between 3/4 and 1 (i.e., 3/4 ≤ x < 1), the second number can be chosen in the range (3/4, 1]. The length of this interval is 1 - 3/4 = 1/4.

Since the probabilities of choosing a number within each interval are equally likely, we need to calculate the weighted average of these probabilities based on the lengths of the intervals.

The probability of choosing a number between 0 and 3/4 is (3/4 - 0) = 3/4, and the probability of choosing a number between 3/4 and 1 is (1/4 - 0) = 1/4.

Therefore, the overall probability is calculated as:

P = (3/4) * (3/4) + (1/4) * (1/4) = 9/16 + 1/16 = 10/16 = 5/8.

So, the probability that the second number chosen will exceed the first number by a distance greater than 1/4 unit on the number line is 5/8.

The volume of the new cone is 1,536π cubic inches.

To find the height of the cone, we can use the formula for the volume of a cone:

V = (1/3)πr²h

Given that the volume of the cone is 414.7 cubic inches and the radius is 6 inches, we can substitute these values into the formula and solve for h:

414.7 = (1/3)π(6)²h

414.7 = (1/3)π(36)h

414.7 = 12πh

h = 414.7 / (12π)

h ≈ 10.93 inches

Therefore, the height of the cone is approximately 10.93 inches when rounded to the nearest whole inch.

Next, let's calculate the volume of the new cone after doubling the radius to 12 inches and changing the height to 8 inches.

Using the same formula, we have:

V = (1/3)π(12)²(8)

V = (1/3)π(144)(8)

Answer: 50$

Step-by-step explanation:

To calculate the amount the college student can spend on fast food in December, we need to find the total amount he can spend in 5 months, given that he wants to spend an average of $50 per month.

Let's start by finding the total amount he can spend in 5 months:

Total amount = 5 x $50 = $250

Now, we can subtract the amount he spent in the other 4 months from the total amount to find out how much he can spend in December:

The amount he can spend in December = Total amount - Amount spent in 4 months

Amount spent in 4 months = $35 + $90 + $15 + $60 = $200

Amount he can spend in December = $250 - $200 = $50

Therefore, the college student can spend $50 on fast food in December to meet his goal of spending an average of $50 per month on fast food for the remaining 5 months of the year.
