Answer:
8640 m, or 8.64 km, assuming it flew in a straight line
Step-by-step explanation:
Distance = rate (or speed) * time (d = rt)
The rate is 4 m/s and the time is 2160 s.
d = rt
d = 4 * 2160
d = 8640 m, or 8.64 km, assuming it flew in a straight line
Which measurement is greater:640 ft or 0.5 mi
Answer:
0.5 mi (2640 feet)
Step-by-step explanation:
Answer:
0.5 mi
Step-by-step explanation:
1 mile = 5280 feet
1 foot = 0.000189394 miles
0.5 miles = 2640 feet
640 feet = 0.121212
therefore, 0.5 mi is greater
(2.3 x 10^-4)(4.5 x 10^6)=
does anyone know the answer to this
Answer:
1035
Step-by-step explanation:
(2.3 × 10^4)(4.5 × 10^6)
First we do the exponents:
10^-4 = 0.0001
10^6 = 1,000,000(1 mil)
Now we plug them into the equation:
(2.3 × 0.0001)(4.5 × 1,000,000)
Now we multiply the numbers in the paranthesis:
(0.00023)(4,500,000) = 0.00023 × 4,500,000
Now we multiply both of them:
0.00023 × 4,500,000 = 1035
I am thinking of a number. When you add the
number to itself then multiply by 3 you get 36.
What is the number?
Hi there! :)
Answer:
[tex]\huge\boxed{6}[/tex]
Let "x" represent a number.
Adding the number to itself gives us x + x, or 2x.
Multiplying by 3 gets 36, therefore:
36 = 3 · 2x
Simplify:
36 = 6x
Divide both sides by 6:
36/6 = 6x/6
x = 6.
Can you help me with that?

(the quantity x to the one-sixth power end quantity to the power of 3.)
Answer:
[tex]\sqrt{x}[/tex]
Step-by-step explanation:
If we have that worded expression, we can convert it into actual mathematical terms.
x to the one sixth power: [tex]x^{\frac{1}{6}}[/tex]
That to the power of 3:
[tex](x^{\frac{1}{6}})^3[/tex]
Using exponent rules, since we have a power to a power, the powers multiply, so:
[tex]x^{\frac{1}{6}\cdot 3}\\\\x^{\frac{3}{6}}\\\\ x^{\frac{1}{2}}[/tex]
If we have a number to a fraction power, the denominator becomes the “find the (denominator) root of x.
So:
[tex]x^{\frac{1}{2}} = \sqrt{x}[/tex]

x 1/2 took the quiz
if the distance between the points (2, -2) and (1, x) is 5 one of the values of x is
Answer:
2.899
Step-by-step explanation:
The formula for calculating the distance between two points P(x1, y1) and (x2, y2) is expressed as:
D = √(x2-x1)²+(y2-y1)²
Given the points (2,-2) and (1,x) and the distance between the point as 5, we are to get x. To get x we will substitute the points and the distance given into the formula.
Given x1 = 2, y1 = -2, x2 = 1, y2 = x and D = 5
On substitution:
5 = √(1-2)²+(x-(-2))²
5 = √1²+(x+2)²
5 = √1+(x+2)²
Square both sides of the equation
5² = (√1+(x+2)²)²
25 = 1+(x+2)²
(x+2)² = 25-1
(x+2)² = 24
Square both sides
√(x+2)² = √24
x+2 = √24
x = √24- 2
x = 4.899-2
x = 2.899
Hence the other value is 2.899
What was the political impact of the Justinian Code?
It reformed old, existing Greek laws.
It made women and enslaved people citizens.
It made Justinian I the emperor of Rome.
It influenced the laws of other countries.
Answer:
The correct option is;
It influenced the laws of other countries
Step-by-step explanation:
The Justinian Code was the rationalization of previous existing Roman laws so as to remove contradiction and eliminate conflicting statutes including the repeal of laws not included in the code.
For close to a millennia, the Justinian Code served as the bedrock of the Byzantine Judiciary and of civil law, fostering law and order for the people of Byzantines and civil law spread to Europe and Latin America.
The Justinian Code influenced the laws of other countries.
The Justinian Code consisted of a collection of older imperial regulations and especially rescripts, which mainly applied during the early 2nd century.It was directly and continuously valid until 1946 in various states and countries that previously belonged to the Eastern Roman Empire. Not only in the East, but also in the West, the creation of Justinian has been attributed authority for centuries by legal scholars, even in areas that had previously fallen outside the Roman sphere of influence. During the Middle Ages, and in many areas afterwards, this law was regarded by legal scholars as an important source of law.Learn more in https://brainly.com/question/1892861

Vishal wants to burn at least 2,400 calories during his weekly workouts. He burns 400 calories per hour swimming and 600 calories per hour rollerblading. He decides to swim for 3 hours this week. How many hours must he rollerblade to reach his goal?
Answer:
2 hours
Step-by-step explanation:
given that the calorie burn rates are:
swimming: 400 cal / hour
rollerblading: 600 cal / hour
If he swims for 3 hours, he will burn:
400 cal / hour x 3 hours
= 1200 cal
Since his goal is 2400 calories, the number of calories that he has left to burn after swimming is:
2400 - 1200
= 1200 calories.
Number of hours of rollerblading to burn 1200 calories
= 1200 calories ÷ 600 calories per hour
= 2 hours

The following list details the numbers of tickets sold for a talent show grade 9:22; grade 10:32; grade 11: 41; and grade 12:30. What are the domain and range of this relation? A domain: (22, 32, 41, 30); range: {9, 10, 11, 12} B. domain: {9, 22, 10, 32); range: {11, 41, 12, 30} C. domain: {9, 10, 11, 12); range: (22, 32, 41, 30) D domain: {11, 41, 12, 30}; range: {9, 22, 10, 32)
Answer:
The correct option is;
C. Domain: {9, 10, 11, 12}; range {22, 32, 41, 30}
Step-by-step explanation:
The given parameters are;
The ticket sold at the talent show for different grades;
For grade 9, 22 tickets were sold
Grade 10, had 32 tickets sale
The number of tickets sold for grade 11 = 41 tickets
The number of tickets sold for grade 12 = 30 tickets
We note that the domain are the inputs and independent variables, x, of a function,f(x), while the range is the set of outputs, dependent, variables, of the function or the values of f(x)
Therefore, given that the domain are the independent variable, that is their values are not influenced by other variables, then the domain are the grades, which are 9, 10, 11, 12, while the range are the range are the number of tickets sold (22, 32, 41, 30) which are dependent on the grades
In a basketball arena, all four sides are filled with people. If each side of the arena is 20 ft. X 30 ft., and each person takes up 2.5 square feet, approximately how many people are in the arena?
Answer:
960 peopleStep-by-step explanation:
If each side of the basketball arena is 20 ft. X 30 ft, the area of each side of the basketball arena = 20ft * 30ft = 600ft².
Since all the four sides are filled with people, the total area of the 4 sides will be expressed as 4*600 = 2400ft²
If each person takes up 2.5ft², total number of people in the arena will be gotten by simply dividing the area of all the four sides by the area took up by each person.
Total number of people in the arena = area of all the four sides by the area/ area took up by each person.
Total number of people in the arena = 2400/2.5
Total number of people in the arena = 960 people.
Hence there are approximately 960 people in the arena.

Answer:
[tex]x=11[/tex]
Step-by-step explanation:
So we have the equation:
[tex]\frac{-2-2x}{3} =-8[/tex]
First, multiply both sides by 3. This cancels out the denominator:
[tex]3(\frac{-2-2x}{3} )=3(-8)[/tex]
The left side cancels. Multiply the right:
[tex](-2-2x)=-24[/tex]
Add 2 to both sides. The 2s on the left cancel:
[tex](-2-2x)+2=(-24)+2\\-2x=-22[/tex]
Divide both sides by -2. The -2 on the left cancel.
[tex](-2x)/-2=(-22)/-2\\x=11[/tex]
Therefore, the answer is 11.
Answer:
x = 11
Step-by-step explanation:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation:
*(-2-2*x)/(3)-(-8)=0
Simplify:
*-2 - 2x / 3
Pull out like factors:
*-2 - 2x = -2 • (x + 1)
Now It should look like this:
-2 • (x + 1) / 3 - (-8) = 0
Rewrite the whole as a equivalent fraction using 3 as the denominator:
*-8 = -8 / 1 = -8 • 3 / 3
Add the two equivalent fractions which now have a common denominator
-Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
*-2 • (x+1) - (-8 • 3) / 3 = 22 - 2x / 3
Pull out like factors:
*22 - 2x = -2 • (x - 11)
Now you should have this:
*-2 • (x - 11) / 3 = 0
Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
-Now, to get rid of the denominator, multiply both sides of the equation by the denominator.
*-2•(x-11) / 3 • 3 = 0 • 3
-Now, on the left hand side, the 3 cancels out the denominator, while, on the right hand side, zero times anything is still zero.
Now you should have this:
*-2 • (x-11) = 0
Now Solve:
x-11 = 0
-Add 11 to both sides of the equation:
x = 11

Answer:
D.
Step-by-step explanation:
4.526 x 10^6 = 4,526,000.
55,246,900 is greater than this.
Answer: Hi!
First, we will find value of the equation given, 4.526 * 10^6.
We will solve the exponent first.
10^6 = 10*10*10*10*10*10 = 1,000,000
Now, we will multiply 1,000,000 by 4.526.
4.526 * 1,000,000 = 4,526,000
4,526,000 is the value of 4.526 * 10^6.
We can automatically tell that d), 55,264,900 is greater than 4,526,000. Therefore, d) is your answer.

What is the length of the diagonal of a square of side 8cm, after getting your answer, put it in one decimal place. 13.1cm 12cm 11.4cm 11.3cm
Answer:
11.3 cm
Step-by-step explanation:
The diagonal d divides the square into 2 right triangles with legs 8 and hypotenuse the diagonal d.
Using Pythagoras' identity in one of the right triangles, then
d² = 8² + 8² = 64 + 64 = 128 ( take square root of both sides )
d = [tex]\sqrt{128}[/tex] ≈ 11.3 cm
Answer:
[tex]\huge\boxed{c = 11.3 cm}[/tex]
Step-by-step explanation:
Using Pythagorean Theorem:
[tex]c^2 = a^2 + b^2[/tex]
Where c is the length of diagonal and a and b are the sides of the square
[Remember that all sides of the square are equal]
=> [tex]c^2 = 8^2 + 8^2[/tex]
=> [tex]c^2 = 64+64\\[/tex]
=> [tex]c^2 = 128[/tex]
Taking sqrt on both sides
=> c = 11.3 cm

Answer:
Option C: x = 300
Step-by-step explanation:
Step 1. Expand the brackets.
When factorising (putting into brackets) and expanding (taking out of brackets), it is always important to remember that the number on the outside multiplies everything on the inside. It is also important to remember the signs of the outside and inside numbers (i.e. if the numbers are positive or negative).
[tex]\frac{1}{3}[/tex](x - 15)
= ([tex]\frac{1}{3}[/tex] × x) - ([tex]\frac{1}{3}[/tex] × 15)
= (x ÷ 3) - (15 ÷ 3)
= [tex]\frac{x}{3}[/tex] - 5
Step 2. Solve the equation.
[tex]\frac{x}{3}[/tex] - 5 = 95
What we want to do is to get x on its own on one side, so that we can figure out the value of x.
[tex]\frac{x}{3}[/tex] - 5 = 95
+ 5 to both sides (do the opposite of what is there, [tex]\frac{x}{3}[/tex] is subtracting 5 right now, but we want to cancel that subtraction out, so we do the opposite of subtraction, i.e. addition)
[tex]\frac{x}{3}[/tex] = 95 + 5
[tex]\frac{x}{3}[/tex] = 100
× 3 to both sides (do the opposite of what is there: x is divided by 3 right now, but we want to cancel that division out, so we do the opposite of division, i.e. multiplication)
[tex]\frac{x}{3}[/tex] x 3 = 100 x 3
x = 100 x 3
x = 300
Step 3. We look for out answer within the options given.
As we can see, the option of [x = 300] is option C, so the answer we would give would be "C".
