Answer:
175.84 m
Step-by-step explanation:
Given that:
A circular garden which has a radius of 28 m.
[tex]\pi[/tex] = 3.14
To find:
The fencing required to enclose the circular garden ?
Solution:
Here, we are given a circle and its radius.
We are required to find the perimeter of the circle in order to find the fencing required to enclose the circular garden..
Formula for finding the perimeter of a circle is:
Perimeter = [tex]2\pi r[/tex]
where [tex]r[/tex] is the radius of the circle.
Using the given values in the formula:
Perimeter = [tex]2\times 3.14 \times 28[/tex] = 175.84 m
Therefore, 175.84 m of fencing is required.
y = pq/p+q
p = 2.4×10^5
Answer:
Step-by-step explanation:
p=2.4×10^5.
q=3.7×10^5
pq = 2.4 * 10⁵ * 3.7 * 10⁵
= 2.4 * 3.7 *10⁽⁵⁺⁵⁾
= 8.88 * 10¹⁰
p + q = 2.4 * 10⁵ + 3.7 * 10⁵
= ( 2.4 + 3.7) * 10⁵
= 6.1 * 10⁵
[tex]y = \frac{pq}{p+q}\\\\ = \frac{8.88*10^{10}}{6.1*10^{5}}\\\\= 1.46 * 10^{10-5}\\= 1.46 * 10^{5}[/tex]

Juana went shopping with $ 50 and spent $ 45. What percentage of her money did she spend?
Answer: 90%
Step-by-step explanation:
Answer:
90%
Step-by-step explanation:
In order to find the percentage of the money Juana spent while shopping, you must take the amount of money spent and divide it by the total amount of money.
$45 dollars spent divided by $50 dollars total will give you your fraction, in decimals:
45 / 50 = 0.90
Multiply by 100% to find your percentage
0.90 * 100% = 90.0%

Answer:
[tex] slope (m) = \frac{1 - (-5)}{2 - (-1)} [/tex]
[tex] = \frac{1 + 5}{2 + 1} [/tex]
[tex] = \frac{6}{3} = 2 [/tex]
Step-by-step explanation:
Find the slope (m) using the two points given, (-1, -5) and (2, 1):
[tex] slope (m) = \frac{rise}{run} = \frac{y_2 - y_1}{x_2 - x_1} [/tex]
Let,
[tex] (-1, -5) = (x_1, y_1) [/tex]
[tex] (2, 1) = (x_2, y_2) [/tex]
Plug in the values into the equation:
[tex] slope (m) = \frac{1 - (-5)}{2 - (-1)} [/tex]
[tex] = \frac{1 + 5}{2 + 1} [/tex]
[tex] = \frac{6}{3} = 2 [/tex]

A boat travels 21 miles due north and then 28 miles due east.Then the boat travels in a straight line back to its starting point.Solve to find the straight line distance of the boat to its starting point.
A.28 miles
B.33 miles
C.35 miles
D.49 miles
When the boat headed 21 miles north then 28 miles to the east then back to its starting point, it formed a right angle triangle. And that straight line the question is talking about is the hypotenuse.
Use the Pythagorean Theorem to solve for hypotenuse.
The Pythagorean Theorem states that for any right triangle the following is true: when you take the sum of both of the legs squared it will equal to the hypotenuse squared.
In equation form: a^2+b^2=b^2
Where the variables a and b are the legs. And the variable c is the hypotenuse.
Plug in the values.
21^2 + 28^2 = c^2
441 + 784 = c^2
1225 = c^2
35 = c
So, the straight line is 35 miles long.

A grain silo is in the shape of a cylinder with a hemisphere top. They cylinder is 20 feet tall. The volume of the silo is 2106 cubic feet. Find the radius of the silo.
Answer:
The radius of the silo is 5.788 feet.
Step-by-step explanation:
Since the silo has the shape of a cylinder, then;
Volume of the silo = Volume of a cylinder = [tex]\pi[/tex][tex]r^{2}[/tex]h
Where: r is the radius of the silo, and h is the height.
Given that: volume = 2106 cubic feet, and height = 20 feet.
Then,
2106 = [tex]\frac{22}{7}[/tex] x [tex]r^{2}[/tex] x 20
2106 = [tex]\frac{440}{7}[/tex][tex]r^{2}[/tex]
2106 x 7 = 440[tex]r^{2}[/tex]
14742 = 440[tex]r^{2}[/tex]
[tex]r^{2}[/tex] = [tex]\frac{14742}{440}[/tex]
[tex]r^{2}[/tex] = 33.5045
⇒ r = [tex]\sqrt{33.5045}[/tex]
= 5.78831
r = 5.788 feet
The radius of the silo is 5.788 feet.

The accompanying diagram shows a flagpole that stands on level ground. Two cables, r and s, are attached to a pole at a point 20 feet above the ground. The combine length of the two cables is 70 feet. If cable r is attached to the ground 8 feet from the base of the pole, what is the measure of the angle, x, to the nearest degree, that cable s makes with the ground? N = 20 ft S 8 t
Answer:
[tex]x\approx24^\circ[/tex]
Step-by-step explanation:
We know that r and s have a combined length of 70. Therefore:
[tex]r+s=70[/tex]
Notice that we can determine r by using the Pythagorean Theorem. In this case, r is the hypotenuse, and 20 and 8 are the legs. Therefore:
[tex]a^2+b^2=c^2[/tex]
Substituting 20 and 8 for a and b and r for c yields:
[tex]20^2+8^2=r^2[/tex]
Compute:
[tex]464=r^2[/tex]
Therefore:
[tex]r=\sqrt{464}=\sqrt{16\cdot 29}=4\sqrt{29}[/tex]
Now, we can determine s. We know that:
[tex]s+r=70[/tex]
So, by substitution:
[tex]s+4\sqrt{29}=70[/tex]
Therefore:
[tex]s=70-4\sqrt{29}[/tex]
Now, notice that, with respect to x, 20 is the opposite side and s is the hypotenuse.
Therefore, we can use the sine ratio. The sine ratio is the ratio between a right triangles opposite side to its hypotenuse.
In this case, the opposite to x is 20, and the hypotenuse is s, or 70-4√29. Therefore:
[tex]\displaystyle \sin(x^\circ)=\frac{20}{s}[/tex]
By substitution:
[tex]\displaystyle \sin(x^\circ)=\frac{20}{70-4\sqrt{29}}[/tex]
Take the inverse sine of both sides:
[tex]\displaystyle x^\circ=\sin^{-1}\Big(\frac{20}{70-4 \sqrt{29}} \Big)[/tex]
Use a calculator. Therefore:
[tex]x\approx24.37^\circ\approx24^\circ[/tex]
Sara can complete 3/4 of a puzzle in 7/8 of an hour. How much a puzzle can she complete in an
hour?
Answer:
x = 6/7 of a puzzle
Step-by-step explanation:
Number of puzzle : time taken
= 3/4 : 7/8
How much a puzzle can she complete in an hour?
Let
x = number of puzzle to complete
Number of puzzle : time taken
= x : 1
Equate both ratios to solve for x
3/4 : 7/8 = x : 1
3/4 ÷ 7/8 = x / 1
3/4 × 8/7 = x / 1
24/28 = x / 1
Cross product
24 * 1 = 28 * x
24 = 28x
x = 24/28
= 6/7
x = 6/7 of a puzzle

Step-by-step explanation:
Tyler is riding his bike from his house to the store, which is 4 MI away. Tyler gets to the store it 18 minutes after he leaves his house.Find Tyler speed in miles per minute.
The formula for speed is given as:
Distance/Time
Hence:
Tyler's distance = 4 miles
Time = 18 minutes
Speed(Miles/ minute) = 4 miles/18 minutes
= 0.2222222222 miles per minutes
= 0.22 miles/minute

Find the maximum walking speed of giraffe with leges 6.03 feet long
Answer:
13.89 ft/s
Step-by-step explanation:
We know that the cheetah is the fastest land animal on Earth, but what if it were not allowed to run? Biologists model maximum walking speed by the equation = √, where g is the acceleration due to gravity (9.8 m/s2 or 32 ft/s2) and L is the length of the leg (in metric or standard units). In the situations below, use this information to answer the questions.
(Hint: It will be useful to know 1 m = 3.23 ft for conversions)
1. Find the maximum walking speed of a giraffe with legs 6.03 feet long.
Solution:
Speed is the ratio of the total distance travelled to the time taken to reach this distance. Speed is given by the formula:
Speed = distance / time
Given that the maximum walking speed (s) is given by the equation:
= √, where g is the acceleration due to gravity (9.8 m/s² or 32 ft/s²) and L is the length of the leg (in metric or standard units).
The giraffe has a length of leg (L) of 6.03 feet, hence:
s = √(32 ft/s² * 6.03 ft)
s = √192.96
s = 13.89 ft/s
WILL GIVE BRAINLIEST IF YOU GIVE AN EXPLANATION. In the packaging part of a warehouse, boxes of blue cups must be moved from the staging area located at an origination point along a conveyor belt described by a vector with components ⟨6, 30⟩. If boxes of red cups are moved 2.5 times the distance along the same belt, which describes the vector that shows the path of the boxes of red cups? Round the magnitude to the nearest whole number if necessary.
Answer:
components: ⟨15, 75⟩, magnitude: about 76
I got this right edge 2020
Component: (15, 75), magnitude about 76 is our correct answer.
Boxes of blue cups moving along a conveyor belt are described by a vector with components (6, 30).
Boxes of red cups are moving along the same conveyor belt but 2.5 times the distance blue cups moved.
We need to find the vector that describes the boxes of red cups and the magnitude of this vector.
What is a vector?A vector is a quantity that has magnitude and direction denoted by:
[tex]V = (V_x, V_y)\\\\Where~~V_x = Vcos\theta~~and~~V_y = Vsin\thetaV_x ~and~V_y~are~ its~ components.[/tex]
Its magnitude is given by:
[tex]|V| = \sqrt{V_x+V_y}[/tex]
Since boxes of red cups move 2.5 times the distance along the same belt as blue cups moved.
We can describe the vector that shows the path of the boxes of red cups as:
= 2.5 x (6, 30)
= ( 2.5x6, 2.5x30 )
= ( 15, 75 )
The magnitude of the vector ( 15, 75 ) is:
[tex]|V| = \sqrt{15^2+75^2}\\\\|V| = \sqrt{225+5625}\\\\|V| = \sqrt{5850}\\\\|V| = 76.48\\\\|V| = 76[/tex]
Rounding 76.48 to its nearest whole number we get,76.
Thus, we have the required vector along with its component as (15, 75) and the magnitude about 76.
