Final answer:

To find the flooded area after 6 minutes, calculate the number of 1/5-minute intervals in 6 minutes, which is 30. Then, multiply by the area flooded in each interval. The flooded area after 6 minutes would be 1500 square feet.

Explanation:

The question is asking to calculate the area that would be flooded by a water pipe after 6 minutes, given that the pipe floods 50 square feet every 1/5 of a minute. To find the answer, we need to determine how many 1/5-minute intervals are in 6 minutes, and then multiply that number by the area flooded in each interval.

First, calculate the number of intervals: 6 minutes × (5 intervals/minute) = 30 intervals.

Next, multiply the number of intervals by the area flooded per interval: 30 intervals × 50 square feet/interval = 1500 square feet.

Therefore, after 6 minutes, the flooded area would be 1500 square feet.

Answer:

Step-by-step explanation:

(0,01)⁻¹/² × ∛(- 343y⁶/1000) =

= -(1/100)⁻¹/² × ∛( - 7³y⁶/10³)

= - 100¹/² × 7y²/10

= -(10²)¹/² × 7y²/10

= - 10 × 7y²/10

= - 7y²

Answer:

-7y^2

Step-by-step explanation:

(0.01)^(-1/2) = (1/0.01)^(1/2) = 100^(1/2) = 10

(-343 × y^6 ÷ 1000)^(1/3) =

(-343)^(1/3) × (y^6)^(1/3) ÷ 1000^(1/3)

= -7 × y^2 ÷ 10 = -0.7y^2

10 × -0.7y^2

Answer:

The length of the side of the triangles are;

First side = 38 ft

Second side = 19 ft

Third side =24 ft

Step-by-step explanation:

To solve the question we are going to take;

Second side is x ft

Since, the first side is 2 times the second side then;

First side of the triangle is 2x ft

Since the third side is 5 ft less than the second side, then;

The third side is (x+5) ft

But, the perimeter of the triangle is 81 ft

Perimeter of a triangle is given by the sum of sides;

Therefore;

x + 2x +(x +5) = 81 ft

4x + 5 = 81

4x = 76

    x = 19 ft

Therefore;

Second side = 19 ft

First side = 38 ft

Third side = 24 ft

Answer:

The correct option is A

Therefore the quadrilateral in the option A can be inscribed in a circle.

Step-by-step explanation:

Given:

Four Quadrilateral, A ,B ,C ,D in the figure below.

For a quadrilateral to be inscribed in a circle we required opposite angles must be supplementary, that is it should add up to 180°.

So from the four given quadrilateral we have only in quadrilateral A the opposite angles are supplementary.

Quadrilateral A :

Consider the quadrilateral PQRS where

∠SPQ = 91°

∠PQR = 101°

∠QRS = 89°

∠SPQ  and ∠QRS  are opposite angles and their sum is 180°

[tex]\angle SPQ+\angle QRS = 91+89 =180[/tex]

Others in option B, C , and D opposite angles are not supplementary hence cannot inscribe in a circle.

Therefore the quadrilateral in the option A can be inscribed in a circle.

Answer:

c Mark me as the brainiest

Step-by-step explanation:

A quadrilateral that can be inscribed in a circle has vertices that lie on a single circle. A distinguishing property of such quadrilaterals is that they have opposite angles adding up to 180°. Non-rectangular parallelograms cannot be inscribed in circles, because their opposite angles are equal rather than supplementary.

We get the same left and right parts, so the equality is true for [tex]k+1.[/tex]

By mathematical induction, this equality is true for all n.

Answer:

58 ounces

Step-by-step explanation:

16 x 4=64 - 6=58 ounces

Final answer:

After converting the weight of the cleats from ounces to pounds, the new weight of Bill's baseball bag is determined to be 3.625 pounds by subtracting 0.375 pounds (weight of the cleats in pounds) from the original 4 pounds.

Explanation:

The subject of this question is Mathematics, specifically dealing with unit conversion and simple subtraction of weights. To determine the new weight of Bill's baseball bag after removing the cleats that weigh 6 ounces, we need to first convert the ounces to pounds, since the weight of the bag is given in pounds.

There are 16 ounces in one pound. Therefore, 6 ounces is equivalent to 6 ounces \/ 16 ounces per pound = 0.375 pounds. Starting with the original weight of the bag which is 4 pounds, subtracting the weight of the cleats in pounds will give us the new weight of the bag.

4 pounds - 0.375 pounds = 3.625 pounds. This is the weight of Bill's baseball bag after the cleats are removed.

Answer:424

Step-by-step explanation:

Answer:

Approximately 490 films were rated R.

Step-by-step explanation:

Total films recently rated is 720. About 68% of the films were rated R. Thus, 68% of 720 is calculated below.

[tex]68\% \: of \: 720 \: films[/tex]

[tex] = \frac{68}{100} \times 720[/tex]

[tex] = 0.68 \times 720[/tex]

[tex] = 489.6[/tex]

[tex] = 490 \: films \: (approximated)[/tex]

Therefore, if 720 films were recently rated, 68% of films rated R is about 490 films.

You'll make 14 dollars.

7% of 50 is 3.5.

If you add 3.5 four times you'll get 14.

200 - 7% is 186.

200 - 14 is 186.

Answer:

$14

Step-by-step explanation:

Well, first find 7% of 50.  To do this you need to make the percent a decimal by moving the decimal that is already(7 is the whole number, if there were any fractions it would be 7.00%) there two space to the left, adding zeros as needed.  

0.07 x 50 = x

3.5 = x

Now you can multiply it by whatever you want.  In this case it would be 4 since 50 time 4 is 200.

3.5 x 4 = 14

So the amount of money that you would make would be $14.

Hope this helped you out.

The actual length of car is 42.857 foot

Solution:

Given that,

The scale of a railroad train set is 3.5 mm to 1 foot

The link of the model car in this it is 150 mm

To find: Length of actual car

Let "x" be the length of actual acr

From given,

Scale is:

3.5 mm : 1 foot

Then, given that link of the model car in this it is 150 mm

Then we get,

3.5 mm : 1 foot

150 mm : x foot

This forms a proportion and we can solve the sum by cross multiplying

[tex]3.5 \times x = 1 \times 150\\\\x = \frac{150}{3.5}\\\\x = 42.857[/tex]

Thus the actual length of car is 42.857 foot

Answer:Type of Angle Description

Acute Angle is less than 90°

Right Angle is 90° exactly

Obtuse Angle is greater than 90° but less than 180°

Straight Angle is 180° exactly

Step-by-step explanation:

Answer:

∠ABC = 62°, ∠DBE = 62°, ∠CBE = 118°, ∠ABD = 118°

Step-by-step explanation:

We can say that angle ABC and angle DBE are vertically opposite angles because there are only two intersecting lines. Vertically opposite angles are equal so we can form an equation:

4x + 2 = 5x - 13

5x - 4x = 2 + 13

x = 15

Now we can substitute x into the equation and find out the value for angles ABC and DBE.

4(15) + 2 = 60 + 2 = 62°, just to make sure we need to substitute x into the other equation to see whether we get the same answer:

5(15) - 13 = 75 - 13 = 62°, now we can confirm that angles ABC and DBE are 62°.

Now we can use the rule, angles on a straight line add up to 180°, to find the other two angles, because these two angles are vertically opposite, they are also equal to each other.

180 - 62 = 118°

Angles CBE and ABD are both 118°

D and E are the only ones true.

Step-by-step explanation:

We want to write 11 out of 40 batters as a decimal.

We can write 11 out of 40 as a fraction to get:

[tex] \frac{11}{40} [/tex]

Note that:

[tex] \frac{11}{40} = \frac{1}{4} \times \frac{11}{10} [/tex]

This implies that:

[tex] \frac{11}{40} = 0.25 \times 1.1[/tex]

This gives us

[tex] \frac{11}{40 } = 0.275[/tex]

Answer:

  V = (4/3)πr³

Step-by-step explanation:

The formula usually used to find the volume of a sphere is ...

  [tex]V=\dfrac{4}{3}\pi r^3[/tex]

where r represents the radius of the sphere.

The actual math involved will depend on what information about the sphere you are given. If you are given the radius or diameter (twice the radius), then this formula will be directly useful.

To determine the volume of a sphere, use the formula V = ([tex]\frac{4}{3}[/tex])πr³. Measure the radius, cube it, multiply by pi, and then multiply by 4/3.

To find the volume of a sphere, you use the formula:

V = ([tex]\frac{4}{3}[/tex])πr³

Here, V stands for volume, r represents the radius of the sphere, and π (pi) is approximately 3.14159.

Step-by-step explanation:

I think it is obtuse and scalene, but I don't think that is the only answer. Hope that can help a little.

The triangle is an isosceles and an obtuse triangle.

A triangle with two sides of equal length is an isosceles triangle. The isosceles triangle has three acute angles, meaning that the angles are less than 90°. The sum of three angles of an isosceles triangle is always 180°.

In an isosceles triangle, the two equal sides are called legs, and the remaining side is called the base. The angle opposite the base is called the vertex angle

The three types of Isosceles Triangles are :

Isosceles acute triangle

Isosceles right triangle

Isosceles obtuse triangle

Given data ,

Let the triangle be represented as ΔABC

Now , the measure of ∠ABC = 120°

So , it is an obtuse triangle with angle > 90°

Now , the measure of sides AB = measure of BC

So , an isosceles triangle, the two equal sides are called legs, and the remaining side is called the base

Therefore , it is an Isosceles obtuse triangle

Hence , the triangle is isosceles

Answer:

Ducks = 8

Horses = 17

Step-by-step explanation:

From the question;

We are required to determine the number of ducks and horses;

We need to know that;

A duck has two legs while a horse has four legs;

Assuming there were x ducks and y horses

Then;

x + y = 25 ................................Eqn 1

And;

2x + 4y = 84 .............................Eqn 2

Solving the two equations simultaneously we can get the number of each animal.

x + y = 25

2x + 4y = 84

Multiplying the first equation by 2, we get

2x + 2y = 50

2x + 4y = 84

Subtracting the two equations;

2x + 2y = 50

2x + 4y = 84

........................................................

      - 2y = -34

          y = 17

Solving for x

x = 25 -17

    = 8

Therefore; there were 8 ducks and 17 horses in the field
