A water pipe floods 50 square feet every 1/5 minute.what is the flooded area after 6 minutes
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.
Find the Sum.

How do you find a volume of a sphere? Please explain. (Also if you can please someone answer the other questions I asked but it has not been answered.)
Thanks!
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:
Measure the radius r of the sphere.Cube the radius (multiply it by itself three times): r³.Multiply the cubed radius by π (pi).Multiply the result from step 3 by 4/3.what is 738 divided by 13 in fraction form

Answer:
See explanation
Step-by-step explanation:
Prove that

in an arithmetic series a1= -14 and a5=30 find the sum of the first 5 terms
The sum of the 5 terms in the arithmetic series is 40.
Step-by-step explanation:
Step 1; First we need to determine the three values between a1= -14 and a5=30. The difference between the first and fifth value = 30 - (-14) = 30 + 14 = 44.
Since there are 4 values after a1 we divide the difference by the number of terms, the difference between each term = 44 / 4 = 11. So the difference between each term is 11.
Step 2; To find out the terms we just add the difference to the previous number.
a1 = -14.
a2 = -14 + 11 = -3.
a3 = -3 + 11 = 8.
a4 = 8 + 11 = 19.
a5 = 19 + 11 = 30.
So a1 + a2 + a3 + a4 + a5 = -14 -3 + 8 + 19 + 30 = 40.
The sum of the first 5 terms in this arithmetic series is 40, calculated based on the formulas for an arithmetic series involving the first term, the fifth term, and the common difference.
Explanation:In an arithmetic sequence or series, the difference between each term (the common difference) is constant. We can represent this as: an = a1 + (n - 1) * d, where d is the common difference. Given in this problem that a1 = -14, a5 = 30, and n = 5.
First, we can find the common difference d using the formula: d = (a5 - a1) / (5 - 1) . So, d = (30 - (-14)) / (5 - 1) = 44 / 4 = 11.
Then, we can find the sum of the first 5 terms using the formula: Sn = n / 2 * (2a1 + (n - 1) * d). That gives us: S5 = 5 / 2 * (2(-14) + (5 - 1) * 11) = 5 / 2 * (-28 + 44) = 5 / 2 * 16 = 40.

for every $50 of candy you sell, you get to keep 7% of it. how much commission do you make if you sell $200 worth of candy?
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.

One side of a triangle is 2 times the second side. The third side is 5 feet longer than the second side. The perimeter of a triangle is 81 feet. Find the length of each side.
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

Approximately 68% of films are rated R. If 720 films were recently rated, how many were rated R?
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]

there are 25 animals in the field. Some are horses, some are ducks. There are 84 legs in all. How many of animal are in the field?
Answer:
Ducks = 8
Horses = 17
Step-by-step explanation:
From the question;
Total number of animals = 25 Total number of legs = 84 legsWe 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

3. Bill's baseball bag weighs 4 pounds. If he takes out a pair of cleats
that weigh 6 ounces, how much will his bag weigh?
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.

A, E
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

A oth grade student can complete 20 multiplication facts in 1 minute. If he works at the same rate, how long should it
take him to complete 35 multiplication facts? (Type your answer as a decimal number]
minutes
It should take the student 1.75 minutes to complete 35 multiplication facts.
To determine how long it will take the 5th grade student to complete 35 multiplication facts at the same rate as 20 facts in 1 minute, we can set up a proportion or use unit rates. Since the student can complete 20 facts in 1 minute, we find the time per fact by dividing the total time by the number of facts:
1 minute / 20 facts = 0.05 minutes per fact
Then, we multiply the rate by the number of new facts:
0.05 minutes per fact * 35 facts = 1.75 minutes
Therefore, it should take the student 1.75 minutes to complete 35 multiplication facts.

Which quadrilateral can be inscribed in a circle?
A) A
B) B
C) C
D) D
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.
