A boat can travel 260 kilometers on 65 liters of gasoline. how much gasoline will it need to go 72 kilometers?
Answer:
0.28
Step-by-step explanation:
72/260=0.276...
0.276...×1
=0.28
18 liters of gasoline will need to go 72 kilometers.
What are Arithmetic operations?Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.
- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.
for example 4 -2 = 2
* Multiplication operation: Multiplies values on either side of the operator
For example 4*2 = 8
/ Division operation: Divides left-hand operand by right-hand operand
For example 4/2 = 2
Let the p liters of gasoline will need to go 72 kilometers
Given that boat can travel 260 kilometers on 65 liters of gasoline
To determine the gasoline will need to go 72 kilometers
⇒ (260 km)/(65 L) = (72 km)/(p L)
⇒ 260/65 = 72/p
⇒ 260p = 65×72
⇒ 260p = 4680
⇒ p = 4680/260
⇒ p = 18
Hence, 18 liters of gasoline will need to go 72 kilometers

What do solving absolute value equations and solving quadratic equations have in common?
Answer:
They often have more than one solution.
Answer:
Step-by-step explanation:
Quadratic equations are equations that when rearranged using the 5 operations can yield a polynomial of degree 2 on one side of the equation and 0 on the other. There are 3 commonly taught methods for solving quadratic equations. These methods are factoring, completing the square, and the quadratic formula. These functions are most commonly used to model projectiles, disregarding air resistance.
When using the factoring method one attempts to write a degree 2 polynomial as the product of two degree 1 polynomials. This method works because if we multiply two degree one polynomials together we find
For example: When factoring , we want to find two number a, b whose product is 6 and sum to 5. The values of a and b we are looking for are 2 and 3.
The method of completing the square centers around using the five operations to replace the original equation with an equivalent equation of the form by taking advantage of the fact that
The absolute value function takes the value of a number, regardless of whether it is positive or negative. Some problems that the absolute value is useful for modeling include an object bouncing on the ground.
For example, , since we do not care about the negative sign.
Example: Solve
Solution: Since the absolute value does not care about whether a number is positive or negative, if then or . Then we can solve each equation individually to find that x = 1 or 5.

What are the basic equations?When two expressions are connected with the equals sign (=) in a mathematical formula, it expresses the equality of the two expressions. An equation is an algebraic statement that demonstrates two mathematical expressions are equivalent in algebra, and this is how it is most usually used. In the equation 3x + 5 = 14, for instance, the two expressions 3x + 5 and 14 are separated by the symbol "equal." When two expressions are joined by an equal sign, a mathematical statement is called an equation. An equation is something like 3x - 5 = 16. By solving for x, we discover that x equals 7, which is the value for the variable.
(1) The sum of the given expressions is given as
(-2×-5-3)+(2×-2)

For each system, choose the method of solving that seems easier to use. Explain why you made each choice. Solve each system.
y= (2/3)x-3
-x+3 y=18
The solution to the system of equations is x = -81 and y = -57. The method of substitution seems easier to use.
To solve the given system of equations, the method of substitution seems easier to use. This choice is made because one of the equations, y = (2/3)x - 3, is already solved for one variable (y). By substituting this expression for y into the second equation, we can solve for the value of x and then substitute it back to find the corresponding value of y.
Using the method of substitution, we substitute (2/3)x - 3 for y in the second equation:
-x + 3((2/3)x - 3) = 18
Simplifying the equation, we have:
-x + (2/3)x - 9 = 18
(2/3)x - x - 9 = 18
(-1/3)x - 9 = 18
Next, we isolate the variable term:
(-1/3)x = 18 + 9
(-1/3)x = 27
To solve for x, we multiply both sides of the equation by -3:
x = -3 * 27
x = -81
Now that we have found the value of x, we can substitute it back into the first equation to find the value of y:
y = (2/3)(-81) - 3
y = -54 - 3
y = -57
Therefore, the solution to the system of equations is x = -81 and y = -57.

Answer:
Lines a and b are perpendicular.
Step-by-step explanation:
When you find the slope of each line, you should use the formula \(\frac{y2-y1}{x2-x1}\). For line a you get the slope to be \(-\frac{4}{3}\), for line b the slope is \(\frac{3}{4}\), for line c the slope is \(\frac{4}{3}\). Because line b is the opposite reciprocal of slope a, we know that these two lines are perpendicular. (opposite reciprocal means to flip the sign in front of the slope and flip the denominator and numerator of the slope)

3- Find all values of Z such that e² = 2+i√3
The values of Z such that e² = 2 + i√3 are Z = ln(2 + i√3) + 2πik, where k is an integer.
To find the values of Z, we can start by expressing 2 + i√3 in polar form. Let's denote it as re^(iθ), where r is the modulus and θ is the argument.
Given: 2 + i√3
To find r, we can use the modulus formula:
r = sqrt(a^2 + b^2)
= sqrt(2^2 + (√3)^2)
= sqrt(4 + 3)
= sqrt(7)
To find θ, we can use the argument formula:
θ = arctan(b/a)
= arctan(√3/2)
= π/3
So, we can express 2 + i√3 as sqrt(7)e^(iπ/3).
Now, we can find the values of Z by taking the natural logarithm (ln) of sqrt(7)e^(iπ/3) and adding 2πik, where k is an integer. This is due to the periodicity of the logarithmic function.
ln(sqrt(7)e^(iπ/3)) = ln(sqrt(7)) + i(π/3) + 2πik
Therefore, the values of Z are:
Z = ln(2 + i√3) + 2πik, where k is an integer.
The values of Z such that e² = 2 + i√3 are Z = ln(2 + i√3) + 2πik, where k is an integer.

Step-by-step explanation:
the measure of the chord- chord angle x is half the sum of the measures of the arcs intercepted by the angle and its vertical angle, that is
x = \(\frac{1}{2}\) (27 + 210)° = \(\frac{1}{2}\) × 237° = 118.5°
The value of x in the given circle by secant lines is 118.5 degrees.
What is Circle?A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.
A straight line that intersects a circle in two points is called a secant line
A chord is in a unique secant line and every secant line defines a unique chord.
The measure of the angle x is half the sum of the measures of the arcs intercepted by the angle and its vertical angle
x=1/2(210+27)
x=1/2(237)
