Answer:
5.02655 units
Step-by-step explanation:
A circle consists of 360 degrees. Thus, 48 degrees is 48/360 of a circle. This relationship transfers to the arc length. The arc length with a central angle of 48 degrees is 48/360 of the entire circle's circumference. Thus:
[tex]Arc(Length) = \frac{48}{360}* 6*2*\pi = 5.02655[/tex]

A traveler is driving across the country and spots Gateway Arch in St. Louis, Missouri. She has read that the arch is 630 feet tall. Her angle of elevation to the top of the arch is 3º. How far away is Gateway Arch, to the nearest tenth of a mile?
Answer:
d = 12,021.1 ft
The Gateway Arch is 12,021.1 ft away
Step-by-step explanation:
Given;
Angle of elevation = 3°
Height of arch = 630 ft
Tanθ = opposite/adjacent
Opposite = 630 ft
Adjacent = d
Substituting the values;
Tan3 = 630/d
d = 630/tan3
d = 12,021.1 ft
The Gateway Arch is 12,021.1 ft away
Answer:
[tex]x = 12021.1\,ft\,(2.3\,mi)[/tex]

The hypotenuse of a right triangle is 10m and the length of one of the legs is 8m , find the length of the other leg of the triangle
Answer:
6 m
Step-by-step explanation:
a squared + b squared = c squared
8 squared plus ? squared = 10 squared
64 + ? = 100
100 - 64 = 36
the square root of 36 is 6
Final answer:
Using the Pythagorean theorem, the length of the other leg of the right triangle is found to be 6 meters.
Explanation:
The student is asking to find the length of the other leg of a right triangle, given the lengths of the hypotenuse (10m) and one leg (8m). To solve this problem, we use the Pythagorean theorem, which relates the lengths of the sides of a right triangle: a² + b² = c², where c is the hypotenuse and a and b are the legs of the triangle. Since the hypotenuse length (c) is 10m and one leg (a) is 8m, we can solve for the length of the other leg (b) using the equation 8² + b² = 10².
First, square the known length of one leg: 8² = 64.
Next, square the hypotenuse: 10² = 100.
Now, subtract the squared length of the known leg from the squared hypotenuse to find b²: 100 - 64 = 36.
Finally, take the square root of 36 to find b: √36 = 6m. So, the length of the other leg is 6 meters.

Use a calculator to solve for xin the equation 2e^3x = 400. Round your answer to
three decimals.
To solve the equation 2e^3x = 400, we isolate e^3x and then use the natural logarithm to solve for x, which gives x ≈ 2.995 when rounded to three decimals.
Explanation:The question asks us to solve the equation 2e^3x = 400 for the variable x. First, we isolate e^3x by dividing both sides of the equation by 2. We get: e^3x = 400/2 which is e^3x = 200. Finding x means solving for 'x' in an exponential equation, which involves using the natural logarithm.
So, our equation becomes: x = ln(200)/3. Using a calculator, x ≈ 2.995 when rounded to three decimals.

Given a+b=7 and a–b=3, find:
3^a/3^b
Answer:
A=-2 and B=3
Step-by-step explanation:
Step 1) Solve the first equation for A:
a+3b=7
a+3b-3b=7-3b
a+0=7-3b
a=7-3b
Step 2) Substitute (7-3b) for a in the second equation and solve for b:
2a=b-7 becomes:
2(7-3b)=b-7
(2*7)-(2*3b)=b-7
14-6b=b-7
14+7-6b+6b=b+6b-7+7
21-0=1b+6b-0
21=(1+6)b
21=7b

Tim's piggy bank contains dimes and nickels worth $5.50. He has 70 coins in all. Use substitution to solve the system of equations to find out how many of each coin Tim has.
Tim has a total of 30 nickels and 40 dimes.
What is Linear Equation?Linear equations are the equations which consist of two or more variables having the exponent of the variable equals 1.
Total number of coins in the Tim's piggy bank = 70 coins
Let d be the number of dime coins and n be the number of nickel coins.
So d + n = 70
Total dollars = $5.50
10 dimes = 1 dollar
1 dime = 1/10 dollar = 0.1 dollar
20 nickels = 1 dollar
1 nickel = 1/20 dollar = 0.05 dollar
0.1 d + 0.05 n = 5.50
So we have two linear equations here : d + n = 70 and 0.1 d + 0.05 n = 5.50.
d + n = 70 ⇒ d = 70 - n
Substituting d = 70 - n in the equation 0.1 d + 0.05 n = 5.50,
0.1 (70 - n) + 0.05 n = 5.50
(0.1 × 70) - 0.1n + 0.05n = 5.50
7 - 0.05n = 5.50
-0.05n = -1.5
n = 30
So d = 70 - n = 70 - 30 = 40
Hence the number of nickel coins is 30 and number of dime coins is 40.

Step-by-step explanation:
since 'A' is the final amount it acts as the 'y' value, and if it's 150 per month then you would multiply the number of months (m) by 150 plus the 400 that was already there.
In a class of 150 students, 95 are taking Math, 75 are taking Science and 55 are taking both.What is the probability that a student is taking neither Math or science?
Answer:
[tex] \frac{7}{30} [/tex]
Step-by-step explanation:
In a class of 150 students, 95 are taking Math, 75 are taking Science and 55 are taking both.
We want to determine the probability that a student is taking neither Math or science.
The number taking only Math is
[tex] = 95 - 55 = 40[/tex]
The number taking only Science
[tex] = 75 - 55 = 20[/tex]
The number of students taking Math, Science, or both
[tex] = 40 + 55 + 20 = 115[/tex]
The number taking neither Mathematics or Science
[tex] = 150 - 115 = 35[/tex]
The probability that a student is taking neither Math or science
[tex] = \frac{35}{150} [/tex]
[tex] = \frac{7}{30} [/tex]

4 strips of paneling 40cm long and 4cm wide are arranged to form a square. What is the area of the inner square in cm
The area of the square will be 640 sq cm.
Step-by-step explanation:
Given,
Number of strip = 4
Length (l) of each strip = 40 cm
Width (b) of each strip = 4 cm
To find the area of the inner square.
Formula
The area of rectangle = l×b
If the area of a square is A, each side will be √A
Now,
Area of each strip = 40×4 sq cm = 160 sq cm
Area of 4 strips = 160×4 sq cm = 640 sq cm
Hence,
The area of the square will be 640 sq cm.

Does anyone knows how to solve this question??
Answer:
24
Step-by-step explanation:
cos(x) is just a trigonometric function. To find it on a right triangle, you take the "adjacent" side, which should be the side next to the angle x, and divide it by the hypotenuse.
In this case, the adjacent side is 12. We don't know the hypotenuse, but we can figure it out using the Pythagorean Theorem: [tex]\sqrt{9^{2}+12^{2}}[/tex] = [tex]\sqrt{225}[/tex] = 15. So, the hypotenuse is 15.
Thus, cos(x) = 12/15 = 4/5. We want 30 * cos(x), so we get: 30 * (4/5) = 24, and that is our answer.
Answer:
24
Step-by-step explanation:
From the mnemonic SOHCAHTOA you would know that cos x = adjacent/hypotenuse.
Adjacent side is given as 12, but we must calculate the hypotenuse.
For that we use Pythagoras.
hypotenuse = √(9²+12²) = 15
Now you can calculate
30×cos(x) = 30×12/15 = 24
Amber is on a family cell phone plan with the other 3 members of her family. The family gets 840 shared cell phone minutes a month, and each family member is limited to his or her equal share of the minutes. The only free calls are calls between family members.
How many minutes per day can Amber talk on her cell phone with her friends during a 30-day month, without going over her share of the minutes?
Minutes per day can Amber talk on her cell phone with her friends during a 30-day month, without going over her share of the minutes will be 7 minutes
ConceptFirst of all we will find the total minutes per family member will get by dividing the total minutes of cell phone plan to total family memberAfter finding total minutes each family member will get we will divide it by 30 to get how many minutes per day Amber will get to talk on her cell phone with her friend.How to solve this problem?The steps are as follow:
Given, there are total 4 family members including Amber.Also the family gets 840 minutes shared cell phone minutes for a monthTo find total minutes per family member we will using following formula:total minutes per family member = total minutes / number of family member
total minutes per family member = 840 / 4
total minutes per family member = 210 minutes
To find the minutes per day Amber will get we will use following formula:Minutes per day Amber will get = total minutes per family member / total days in month
Minutes per day Amber will get = 210 / 30 = 7 minutes per day
So Amber will get 7 minutes per day to talk on her cell phone with her friends during a 30-day month, without going over her share of the minutes
