Answer: $3.20

Step-by-step explanation:

We have

15-mile stretch = $0.60

80-mile stretch = x

Cross Multiply

15 × x = 80 × $0.60

x = 80 × $0.60/15

x = $3.20

Hence, the cost to drive an 80-mile stretch is $3.20

6 [tex]\frac{2}{3}[/tex] cups

Step-by-step explanation:

we can set up a proportion:

[tex]\frac{4}{3}[/tex] = [tex]\frac{t}{5}[/tex]     't' equals the number of cups of peanuts to make 5 cups trail mix

now we can cross-multiply to get:

3t = 20

t = 20/3 or 6 2/3 cups

The final velocity in the given equation is −0.5, when the acceleration is -5.

The distance covered by a body in one unit of time in a specific direction is referred to as velocity. M/s is always the only metric unit of velocity.

Speed and velocity are different in that:

v = u + at

here,

a = average acceleration

v = final velocity

u = initial velocity

t = time

given,  u = 2

a = -5

t = 1/2 = 0.5

putting the values

v = 2 + (-5)(0.5)

v = 2 - 2.5

v = −0.5

Thus, The final velocity in the given equation is −0.5, when the acceleration is -5.

As a result, the answer to the provided coordinate plane problem is only choice C), which is the right answer.

The term "coordinate plane" refers to a two-dimensional region that consists of two number lines. It emerges when the X-axis & Y-axis intersect at a location known as the origin. Using the numbers on a coordinate grid, one can locate points.

Here,

Since, If there is a coordinate plane with both parallel lines, go with option A.

Therefore, there is no cure.

There are hence a finite number of solutions that could be found.

If two lines cross, there is only one potential result for Option B. Consequently, the quantity of potential solutions is.

According to Option C, there must be an endless number of solutions to the system because there are two coinciding lines that provide us an infinite number of junction sites.

The difference between Option D) and Option B) is noted.

A transformation modifies the parent function's graph.

The graph of a parent function is changed by a transformation. Transformations come in three different flavors: translations, reflections, and dilations.

A point, line, or geometric object can be changed in four different ways that are all collectively referred to as transformations. The pre-image is the shape of the object as it was originally, and the transformed shape of the object is termed the image.

Making pictures or replicas of an object is part of transformation geometry. You are introduced to transformation geometry in grade 9 through the use of translation, reflection, dilation, and rotation.

The foundation of the problem transformation approach is the notion that, if we are unable to address the given problem directly, we will move it to a setting where we can do so. The method's fundamental component is how the problem is broken down into smaller tasks.

The zeros of the polynomial x3 + 2x2 - x - 2 are -1, -2 and 4.

The given polynomial is x3 + 2x2 - x - 2. To find the zeros of this polynomial, we need to solve the equation x3 + 2x2 - x - 2 = 0.

Rewrite the equation as x3 + 2x2 - x - 2 = 0.

Factor the equation.

Set each factor equal to zero and solve for x.

(x + 2)(x2 - x - 1) = 0

x + 2 = 0

x = -2

(x2 - x - 1) = 0

x2 - x - 1 = 0

x2 - 1x - 1 = 0

Apply the quadratic formula to solve for x.

x = [-b ± √(b2 - 4ac)] / 2a

x = [(-1) ± √(1 - 4*1*(-1))] / 2*1

x = [(-1) ± √(5)] / 2

x = [-1 ± √5] / 2

x = [(-1 + √5) / 2] and [(−1 - √5) / 2]

Simplify the solutions and find the zeros of the polynomial.

x = (-1 + √5) / 2  and x = (-1 - √5) / 2

The longitudes are also referred to as meridians and they are used to measure the exact location of any place on the earth's surface. This helps in navigation and also in mapping the world. Each meridian is assigned a numerical value, ranging from 0 degrees at the Prime Meridian to 180 degrees at the International Date Line.

What is slope intercept form?

The equation of the line can be written in different ways. One of the methods of writing equations of a line is slope intercept form.

The line with m as the slope, and c as the y-intercept is the graph of the linear equation y = mx + c. This form of linear equation is known as slope intercept form. The values of m and c are real integers in the slope-intercept form of the linear equation.

The slope, m, is a measure of how steep a line is. A line's y-intercept, c, denotes the y-coordinate of the location where the line's graph crosses the y-axis.

For farmer Dubble,

      Number of elentires in beginning c = 87

      Number of elentires destroyed every month m = -5

Answer: The measure of the third side of a triangle, when the measures of the other two sides are 13 in and 27 in, must be greater than the difference between the measures of the other two sides (which is 27 in - 13 in = 14 in) and less than the sum of the measures of the other two sides (which is 27 in + 13 in = 40 in).

This is because according to the triangle inequality theorem, the sum of the lengths of any two sides of a triangle must be greater than the length of the third side. So the measure of the third side must be between the difference of the two given sides and the sum of the two given sides.

Therefore the range of the measure of the third side of a triangle with side lengths 13 in and 27 in is:

(14 in < x < 40 in)

or

[x > 14 in and x < 40 in].

It is also important to note that any value of x within this range will produce a valid triangle, however any value less than 14 in or greater than 40 in will not.

The amount of time he spent on the bicycle is 5.5 hours.

Jim began a 167​-mile bicycle trip to build up stamina for a triathlete competition.​ Unfortunately, his bicycle chain​ broke, so he finished the trip walking.

The whole trip took 6 hours. Jim walks at a rate of 4 miles per hour and rides at 30 miles per​ hour.

The amount of time he spent on the bicycle can be calculated as follows;

speed = distance / time

distance = speed × time

Therefore, total distance is as follows:

let

x = time spent walking

167 = 4x + 30(6 - x)

167 = 4x + 180 - 30x

167 = -26x + 180

167 - 180 = -26x

x = -13 / -26

x = 1 / 2

By Using Pythagorean Theorem, the value of x is 6.2 units.

Pythagorean Theorem:

In mathematics, the Pythagorean Theorem or Pythagorean Theorem is the fundamental relationship in Euclidean geometry between the three sides of a right triangle. It states that the area of ​​a square whose side is the hypotenuse (opposite the right angle) is equal to the sum of the areas of the squares on the other two sides. This theorem can be written as an equation for the lengths of sides a, b and hypotenuse c and is often called the Pythagorean equation.

                              a² +b² =c²

Now,

By using the Pythagorean theorem:

Hypotenuse² =  Perpendicular² + Base²

Now,

In the Δ ABD

As given

DB² = DA² + AB²

As given

DB = 13 units

AB = 9 units

Putting values in the above

13² = 9²+ DA²

169 - 81 = DA²

88 = DA²

Now,

In ΔABC

AB² = AC² + CB²

(As given AB = 9 units , CB = x)

9² = AC² + x²

AC ² = 81 - x²

Now in ΔADC.

AD² = AC² + DC ²

As

AC ² = 81 - x²

DC = 13 - x

AD = [tex]\sqrt{88}[/tex]

(√88)² = 81 -x² +( 13 - x²)

By using the formula (a + b)² = a² + b² + 2ab

    88 = 81 - x² + 13²- 2 × 13 × x + ²

⇒ 88 = 81 - x² + 13² - 26x + x²

⇒ 88-81 - 169 = -26x

⇒ 88-250 =-26x

⇒ -162 = - 26x
