Answer: 495
Step-by-step explanation: If the car traveled for 90 miles on 2 gallons of gas and we now have 11 gallons Divide 2÷11 = 5.5 or
90×5.5 = 495
The number of miles Aubrey's car can travel is 495 miles
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the distance traveled by Aubrey's car for 11 gallons be = A
Now , the equation will be
The distance traveled by Aubrey's car for 2 gallons = 90 miles
So ,
The distance traveled by Aubrey's car for 1 gallon = distance traveled by Aubrey's car for 2 gallons / 2
The distance traveled by Aubrey's car for 1 gallon = 90 / 2
The distance traveled by Aubrey's car for 1 gallon = 45 miles
So , the equation will be
The distance traveled by Aubrey's car for 11 gallons A = The distance traveled by Aubrey's car for 1 gallon x 11
The distance traveled by Aubrey's car for 11 gallons A = 45 x 11
The distance traveled by Aubrey's car for 11 gallons A = 495 miles
Therefore , the value of A is 495 miles
Hence , The number of miles Aubrey's car can travel is 495 miles

Bill Murray has 16 3/4 days of vacation per year. To date, he has taken 1 3/4 days in January, 4 2/3 days in February, and 2 1/6 days in March. How much more vacation time is Bill entitled to?
Step-by-step explanation:
16 3/4 days in total.
that are (16×4 + 3)/4 = 67/4 days.
he has taken
1 3/4 = (1×4 + 3)/4 = 7/4 days
4 2/3 = (4×3 + 2)/3 = 14/3 days
2 1/6 = (2×6 + 1) = 13/6 days
to be able to add abd subtract them directly, we need to bring all fractions to the same denominator.
we have 3, 4, 6 : the smallest common multiple is 12 (can be divided without remainder by 3, 4 and 6).
we need to multiply each fraction by a fitting n/n factor to bring the denominators to 12 and keep the overall value of the fraction unchanged.
67/4 = 67/4 × 3/3 = 201/12
7/4 = 7/4 × 3/3 = 21/12
14/3 = 14/3 × 4/4 = 56/12
13/6 = 13/6 × 2/2 = 26/12
the remaining vacation time is
201/12 - 21/12 - 56/12 - 26/12 = 98/12 = 49/6
49/6 = 8 and remainder 1 = (8×6 + 1)/6 = 8 1/6 days
9 less than 18 times a number x
Answer: 18x- 9
Step-by-step explanation:
1.) Put the numbers in their correct lineup. 18 * x - 9
2. Add parentheses around 18 * x, secluding them away from the -9.
(18 * x) -9
3.) Remind yourself of PEMDAS (Parentheses, Exponents, Multiplication, Division, Add, and Subtract). In this equation, 18 * x are in parentheses().
(18 * x)
4.) Multiply 18 * x... Which equals 18x.
5. Equation should now look like : 18x - 9
6. You can't combine those two numbers because the coefficiant (The coefficiant is 18.) and the regular number (-9) are not equal.
8. Answer : 18x-9

In figure , ABllEF, angle ABC=
[tex] {70}^{0} [/tex]
and angle EFD =
[tex] {40}^{0} [/tex]
then find x
Answer:
x = 110°
Step-by-step explanation:
It is given that,
→ AB || EF
→ <ABC = <CEF
→ <CEF = <DEF
Then the value of <DEF will be,
→ <DEF = 70°
Now according to Exterior angle property of a triangle the value of x will be,
→ x = <DEF + <EFD
→ x = 70 + 40
→ [ x = 110° ]
Hence, the value of x is 110°.
Answer:
x = 110°
Given:
AB||EF means the sides are parallel and the angle is same in both.
[tex]\triangle ABC = \triangle FED[/tex]Find the missing angle inside the triangle:
= 180° - (40° + 70°)
= 180° - 110°
= 70°
Now the missing angle and x sum ups to 180° on a straight line:
x + 70° = 180°x = 180° - 70°x = 110°Un ganadero tiene tiempo suficiente para alimentar 220 vacas durante 45 días. ¿cuántos días podrá alimentar con la misma cantidad de tiempo a 450 vacas?

If the parent function f(x) = |x| is transformed to g(x) = |x + 5|, what transformation occurs from f(x) to g(x)?
The transformation that occurs from f(x) to g(x) is the graph of f(x) is shifted to the left to create g(x).
What transformation occurs from f(x) to g(x)?The equations of the functions are given as
f(x) = |x|
g(x) = |x + 3|
The above implies that
g(x) = f(x + 3)
When a function is shifted to the left by h units, it is represented as
g(x) = f(x + h)
This means that
h = 3
So, the transformation that occurs from f(x) to g(x) is the graph of f(x) is shifted to the left to create g(x).
Hence, the required transformation that occurs from f(x) to g(x) is the graph of f(x) is shifted to the left to create g(x).

log_(4)9x^(2)=log_(2)(5x-8). Solve for x
The value of x in the logarithm equation log₄(9x²) = log₂(5x - 8) is x = 4
How to solve for x in the equation?The equation is given as
log₄(9x²) = log₂(5x - 8)
Apply the change of base law of logarithm
So, we have
log(9x²)/log(4) = log₂(5x - 8)
Express 4 s 2^2 and 9 as 3^2
So, we have
log(3x)²/log(2²) = log₂(5x - 8)
Apply the power law of logarithm
So, we have
2log(3x)/2log(2) = log₂(5x - 8)
Evaluate the quotient
So, we have
log(3x)/log(2) = log₂(5x - 8)
Apply the change of base law of logarithm
So, we have
log₂(3x) = log₂(5x - 8)
Cancel out the common base
So, we have
3x = 5x - 8
Collect the like terms
So, we have
3x - 5x = - 8
Evaluate the like terms
So, we have
-2x = - 8
Divide both sides by -2
So, we have
x = 4
Hence, the value of x in the logarithm equation log₄(9x²) = log₂(5x - 8) is x = 4

Step-by-step explanation:
so, first $300 must be paid without any ifs and whens.
for the rest of the amount the insurance will cover 70%.
the bills total to
700 + 930 = $1630
he must pay $300 of that directly.
that leaves 1630 - 300 = $1330 for the 70/30 split between insurance and patient.
the patient must pay 30% of these $1330.
100% = 1330
1% = 100%/100 = 1330/100 = $13.30
30% = 1% × 30 = 13.30 × 30 = $399
so, the patient pays
300 + 399 = $699
of the $1630 bill.
if the hypotenus of a right triangle is 6 m and one side is 4 m, what's the length of the other side
Answer:
[tex]\sqrt{20} \text{ or } 2\sqrt{5}[/tex]
Step-by-step explanation:
So in this question we want to use the Pythagorean Theorem which essentially gives us a relationship between the sides of a triangle and is as follows: [tex]a^2+b^2=c^2[/tex]
In this formula the "a" and "b" represent the base and the height and "c" represents the hypotenuse of the triangle
The order in which you assign "a" and "b" do not matter, so let's just say that: [tex]a=4\ \text{and}\ c=6[/tex]
Although it is important that you assign the hypotenuse to "c".
So plugging in known values we have the equation:
[tex]4^2 +b^2=6^2[/tex]
Square the values
[tex]16+b^2=36[/tex]
Subtract1 16 from both sides
[tex]b^2=20[/tex]
take the square root of both sides
[tex]b=\sqrt{20}[/tex]
This "b" represents our other side, which we did not initially know, so this is our answer :)
You can simplify this further by separating the radical into: [tex]\sqrt{20} = \sqrt{4} * \sqrt{5} = 2\sqrt{5}[/tex]

Slope = 2/3
Equation of a line, y = mx + c
Where, m is the slope and c is the y-intercept.
Here, m is 2/3.
The point at the x-intercept has co-ordinates : (-3, 0)
Where, x is -3 and y is 0.
So, substitute the values in equation:
