A village is 10km on a bearing 050° from a point O. Calculate how far the village is north of O.
Answer:
7.66 km
Step-by-step explanation:
Let distance village is ; north of O = x
Using Pythagoras rule :
Sinθ = opposite / hypotenus
Opposite = x
Hypotenus = 10
θ = 50°
Sin50 = x / 10
0.7660444 = x / 10
x = 0.7660444 * 10
x = 7.6604444
x = 7.66

A sphere and a cylinder have the same radius and height. The volume of the cylinder is 11 feet cubed.
A sphere with height h and radius r. A cylinder with height h and radius r.
Which equation gives the volume of the sphere?
V = four-thirds (11) pi
V = two-thirds (11) pi
V = four-thirds (11)
V = two-thirds (11)
9514 1404 393
Answer:
V = (2/3)(11)
Step-by-step explanation:
The given cylinder has a height of 2r, so its volume is ...
V = πr²(2r) = 2πr³
The volume of a sphere is given by ...
V = 4/3πr³
Then the ratio of the volume of the sphere to the volume of the cylinder is ...
(4/3πr³)/(2πr³) = (4/3)/2 = 2/3
So, the volume of the sphere is 2/3 times the volume of the cylinder:
V = (2/3)(11)

The distance from Charles's house to his school is 3 miles. His father gave him a ride for 1,760 yards, and he walked the rest of the way. The distance that Charles walked is miles or yards. (Hint: 1 mile = 1,760 yards.)
Answer:
2 miles or 3520 yards
Step-by-step explanation:
The distance from Charles's house to his school is 3 miles. His father gave him a ride for 1,760 yards, and he walked the rest of the way. The distance that Charles walked is miles or yards. (Hint: 1 mile = 1,760 yards.)
From the Question, we know that
1 mile = 1,760 yards..
His father gave him a ride for 1,760 yards,
Hence, the number of miles Charle's father drove him was 1 mile
The distance that Charles walked in miles is calculated as:
3 miles - 1 mile
= 2 miles
Converting to yards
1 mile = 1,760 yards..
2 miles = x
Cross Multiply
x = 2 × 1760 yards
= 3520 yards
What is 11 divided by 5 as a fraction
11 divided by 5 is equal to the fraction 11/5, which can also be expressed as the mixed number [tex]2\frac{1}{5}[/tex] .
What is 11 divided by 5 as a fraction?To convert the division of 11 by 5 into a fraction, we can express it as a ratio of two integers. Here's how we can derive the fraction:
When we divide 11 by 5, we get a quotient of 2 with a remainder of 1. So, we can write the division as:
11 ÷ 5 = 2 + 1/5
Since 2 is a whole number, we can express it as a fraction with a denominator of 1:
2 = 2/1
Now, we can rewrite the division using the same denominator:
11/5 = 2/1 + 1/5
To combine the fractions, we need a common denominator. The least common multiple (LCM) of 1 and 5 is 5. Therefore, we can multiply the fractions by appropriate values to make their denominators equal to 5:
11/5 = (2/1) × (5/5) + (1/5) = 10/5 + 1/5
Now that the denominators are the same, we can add the fractions:
11/5 = (10 + 1)/5 = 11/5
Therefore, the division of 11 by 5 can be expressed as the fraction 11/5.
The fraction 11/5 represents the result of dividing 11 into 5 equal parts. Each part would be equal to 11/5. It can also be simplified to a mixed number as 2 1/5, where the whole number part is 2 and the fractional part is 1/5.
So, 11 divided by 5 is equal to the fraction 11/5, which can also be expressed as the mixed number 2 1/5.

Ronald is buying a rectangular chest to store his carpentry tools. The height of the chest, in feet, is represented by the function H(x) = x+6.
The area of the base of the chest, in square feet, is represented by the function A(x)= 20 square root x/ 3. In both functions, x represents the width of the
chest in feet.
To find a function that represents the volume of the chest, Ronald should ? Functions H(x) and A(x)

Answer:
Multiply ; 40
Step-by-step explanation:
Given that :
Height, H of rectangular chest = H(x) = x+6.
Area of rectangular chest, A(x) = 20√x /3
Recall; Volume of chest = Base area * Height
(X + 6) * 20√x /3
(20x√x /3 ) + (20 * 6√x/3)
(20x√x /3 ) + (20 * 2 * 3√x/3)
(20x√x/3) + 40√x
The correct answer for the drop-down menu is that the first blank is multiply and the second blank is 40.
What is the function about?Based on the fact that we have been given the Height =H of rectangular chest to be:
= H(x) = x+6.
When the Area of rectangular chest:
A(x) = 20√x /3
Note that: Volume of chest = Base area x Height
Therefore:
(X + 6) * 20√x /3
(20x√x /3 ) + (20 * 6√x/3)
(20x√x /3 ) + (20 * 2 * 3√x/3)
(20x√x/3) + 40√x
Therefore, the correct answer for the drop-down menu is that the first blank is multiply and the second blank is 40.

What is a Polynomial?Polynomial, a mathematical expression made comprised of numbers and variables arranged in specific patterns.
As per the given data:
We are given the equation of a cubic polynomial x³ + 3x² - x - 3.
The zeroes of the given cubic polynomial are also given.
We have to verify that the zeroes of the cubic polynomial are correct, and they satisfy the relationship between zeroes and the coefficient.
For a polynomial p(x) is p(a) = 0 then a is a zero of p(x).
Checking the given zeroes similarly:
For 1:
1³ + 3(1)² - 1 - 3 = 0
1 + 3 - 1 - 3 = 0
0 = 0
1 is a zero
For -1:
(-1)³ + 3(-1)² - (-1) - 3 = 0
-1 + 3 + 1 - 3 = 0
0 = 0
-1 is a zero
For -3:
(-3)³ + 3(-3)² - (-3) - 3 = 0
-27 + 27 + 3 - 3 = 0
0 = 0
-3 is a zero
For ax³ + bx² + cx + d = 0, the sum of all the roots should be equal to
= (-b)/a
Similarly, for x³ + 3x² - x - 3:
1 + (-1) + (-3) = (-3)/1
1 - 1 - 3 = -3
-3 = -3
1,-1,-3 are the zeroes and the relationship between zeroes and the coefficient is verified.
Hence, 1,-1,-3 are the zeroes and the relationship between zeroes and the coefficient is verified.
