To ensure that the car has enough petrol of a trip, we get that it should have 52.58 liters of petrol.
We are given that:
For 27 liters of petrol, we can drive a car for 95 km.
SO, by using the unitary method, we get that:
for 1 km of journey, the liters of petrol that we need is = 27 / 95 liters.
1 km = 27 / 95 liters
For 185 km, we get that:
185 km = 27 / 95 × 185 liters
185 km = 52.58 liters.
Therefore, to ensure that the car has enough petrol of a trip, we get that it should have 52.58 liters of petrol.

Bronson is creating a right triangular flower bed. If two of the sides of the flower bed are 7 feet long each, what is the length of the third side to the nearest foot?
The length of the third side of the right triangular flower bed is 10 feet.
A right-angled triangle is a triangle with one of its interior angles equal to 90°. The side opposite to the right angle is the largest side and is referred to as the hypotenuse. Hypotenuse is always greater than any of the other two sides.
If two of the sides of the flower bed are 7 feet long each, then these are the sides adjacent to the right angle. We are to find the length of the third side, which is the hypotenuse, using the Pythagorean theorem.
Pythagorean Theorem states that the square of the length of the hypotenuse of a right-angled triangle is equal to the sum of the squares of the two other sides.
c^2 = a^2 + b^2
where a and b are the adjacent sides to the right angle
c is the hypotenuse
c^2 = 7^2 + 7^2
c^2 = 49 + 49
c^2 = 94
c = 9.899
Hence, he length of the third side of the right-angled triangular flower bed is 10 feet.

An airplane on a long-distance flight flew the first 1295 miles of it's journey on 3 hours and 33 minutes. After that, the wind changed, and it took the plane 1 hour and 47 minutes to cover the remaining 738 miles. What was the plane's average speed during the flight?
Round to the nearest tenth
The plane's average speed during the flight is 381.43 miles per hour.
What is the average speed?The average speed is the quotient of the total distance covered during the flight divided by the total time used.
The Average Speed is the scalar quantity that shows the rate of change in displacement from one point to another.
Data and Calculations:The distance for the first miles = 1,295 miles
The time it took the plane to cover the distance = 3 hours 33 minutes
The distance for the last lap = 738 miles
The time it took the plane to cover the last distance = 1 hour 47 minutes
The total distance covered for the journey = 2,033 miles (1,295 + 738)
The total time for the journey = 5 hours 20 minutes or 5.33 hours
Average Speed = 2,033/5.33
= 381.43 miles per hour
Thus, the plane's average speed during the flight is 381.43 miles per hour.

How is -89 represented using 8-bit two's compliment? (the answer should be 8 binary digits)
-89 can be represented by using 8-bit two's compliment as 10100111.
What is binary encoding?Binary encoding can be defined as a standard technique that is designed and developed to convert data in plain text (source alphabets) to a form that is easily used by different operating systems (OS), especially through the use of a binary digit (bit) or two-symbol system.
In Computer programming, two's complement of base-10 is generally easier to implement because it has a single representation of 0 only.
How to convert a binary (base-10) to decimal (base-2)?First of all, we would determine the positive version of -89, which is 89:
2 | 89
2 | 44 R 1
2 | 22 R 0
2 | 11 R 0
2 | 5 R 1
2 | 2 R 1
2 | 1 R 0
2 | 0 R 1
Next, you would read the decimal number (base-2) upward and this gives:
89₂ = 01011001.
For the negative integer number representation on 8-bits, we would replace all the 0s with 1s and the 1s with 0s as follows:
01011001 = 10100110
For the 8-bit two's complement, we would add 1 to the above number:
-89 = 10100110 + 1
-89 = 10100111.

Two angles form a linear pair. The measure of one angle is 3.5 times the measure of the other angle. Find the measure of each angle.
Given that the two angles form a linear pair, the measure of each angle is 40° and 140°.
What is the measure of each angle?The sum of angles of a linear pair is always equal to 180°.
Given the data the data in the question;
Let x represent the measure of the first angle.
Measure of angle 1 = xMeasure of angle 2 = 3.5xSince the sum of angles of a linear pair is always equal to 180°.
m∠1 + m∠2 = 180
x + 3.5x = 180

x-y=4 et xy=21 calculer x^3-y^3
Answer:
316 or -316.
Step-by-step explanation:
x^3 - y^3 = (x - y)(x^2 + xy + y^2)
= 4(x^2 + y^2 + 21)
x - y = 4
xy = 21
Substitute x = 4 + y in the last equation
(4 + y) y = 21
y^2 + 4y - 21 = 0
(y + 7)(y - 3) = 0
y = 3, -7.
So, x = 7, - 3.
So, x and y are 7 and 3 or -7 and -3.
But x^2 + y^2 = 9 + 49 = 58 whichever is true,
So, x^3 - y^3
= 4(x^2 + y^2 + 21)
= 4 (58 + 21)
= 316,
If x = -3 and y = -7 , then the answer is
-316.
Make a conjecture about the measure of an exterior angle and the sum of the measures of its nonadjacent interior angles.
Here we can conjecture that :
The measure of an exterior angle is equal to the sum of measures of its nonadjacent interior angles.
What is interior and exterior angle ?The exterior angle of any polygon is defined as the angle which is at the outside boundaries of that polygon. whereas, the interior angle is defined as the angle which is inside the polygon. In the other words if the polygon has the point within the angle it is in the interior of the angle , but if the point is outside then is it said to be in the exterior of the angle.
What is Non adjacent interior angle ?Non adjacent angles are those angles which are not adjacent to each other. The non adjacent angles follow one of the properties which are listed below:
They do not share a common vertex or common side.They can share a side, but not share the common vertex.They share a common vertex, but not share the common side.In the given question,
taking a example say a triangle ABC with ∠A=64, ∠B = 45 and an external angle x to the side AC.
as sum of angles equal to 180
thus, ∠A + ∠B + ∠C = 180
64 + 45 + ∠C = 180
∠C = 180-109 = 71
now as x is external to ∠C,
therefore x = 180 - ∠C = 180 - 71
x = 109 = ∠A + ∠B
Hence we can make the conjecture that, the measure of an exterior angle is equal to the sum of measures of its nonadjacent interior angles.

We have an equation 2/x = x/2.
As we know that, as we know that, an equation is a condition on a variable such that two expressions in the variable should have equal value.
Therefore, the solution of the equation 2/x = x/2 is given by
2/x = x/2
⇒ 2 = (x/2)x (multiplying both the sides by x)
⇒ 2 = x^2/2
⇒ 2(2) = x^2 (multiplying by 2 both the sides by 2)
⇒ 4 = x^2
⇒ x^2 = 4
⇒ x = √4
⇒ x = ±2

Now we will check 2 is the solution of the given equation or not.
Therefore,
LHS = 2/2 = 1
RHS = 2/2 = 1
Here, LHS = RHS. Therefore, 2 is the solution of the given equation.
Similarly, for -2
LHS = 2/-2 = -1
RHS = -2/2 = -1

Further, at 4 minutes, the distance covered increases to 0.8 miles. At 6 minutes, the distance covered again increases by 0.4 miles and is 1.2 miles. At 8 minutes, the distance covered in 1.6 miles, which again increases by 0.4.
