first we can separate the values ​​with exponents that having the same base can be reduced

so

now do the multiplication between 4.8 and 2.2 and reduce the fraction

so, the right option is B

The mixed fraction form

is equivalent to

since 5/6 is equal to 0.8333, then

Therefore, since 5.83333 is greater than 5.6, then 5 5/6 is greater than 5.6

To first start our problem, we will draw some coordinate axis at point E, since we are rotating the figure around this vertex. We get something like this

We are going to fix the point E. But we are going to rotate the figure in the direction in which the arrow shows. Since it is a 90° rotation, our goal is to align the blue vertical line, with the red horizontal line, following the direction of the black arrow. The picture would look like this

Note that the lengths of the new figure should remaing the same. That is, the side H' E should have a length of 3 squares and the length of H' G' should be 2 squares.

a) From the graph,

shortest side length of original figure = 1/2 units

By dilating the original figure by 4, we would multiply each length by 4

Thus,

shortest side length of final figure = 1/2 x 4 = 2 units

b) shortest side length of the final figure = 4 x shortest side length of the original figure

c) A dilation with a positive scale factor greater than 1 gives an enlarged figure.Thus, the answer is False

d) After dilation, the original and final figures are similar. Thus, the answer is False

Triangles that have two sides at least equally spaced apart are said to be isosceles. As three-sided enclosed polygons with three sides, triangles are known to exist. Depending on the length of their sides, triangles can be categorized as equilateral, isosceles, or scalene.

The three interior angles of a triangle will always have a sum of 180°. A triangle cannot have an individual angle measure of 180°, because then the other two angles would not exist (180°+0°+0°).

So ,

x +x+38 = 180

2x = 180 -38

2x = 142

x = 71

Answer:

No, it is not proportional because 7.5 miles in 6 hours is not equivalent to 12 miles in 8 hours.

Step-by-step explanation:

The correct relationship between the hikers distance and time is;

No, it is not proportional because 7.5 miles in 6 hours is not equivalent to 12 miles in 8 hours.

What is Proportional?

Any relationship that is always in the same ratio and quantity which vary directly with each other is called the proportional.

Given that;

A group of hikers tracked how long it took to hike a 20-mile trail.

And, They hiked 3.75 miles in 3 hours, 7.5 miles in 6 hours, and 12 miles in 8 hours.

Now,

Find the proportional as;

For hiked 3.75 miles in 3 hours,

Proportional = 3.75 / 3

                   = 1.25

For hiked 7.5 miles in 6 hours,

Proportional = 7.5 / 6

                   = 1.25

For hiked 12 miles in 8 hours,

Proportional = 12 / 8

                   = 1.5

Thus, The correct relationship between the hikers distance and time is;

No, it is not proportional because 7.5 miles in 6 hours is not equivalent to 12 miles in 8 hours.

Cost of 1 slice of pizza and 3 sodas = $5.25

When the requirements of a mathematical model are represented by linear relationships, the best result can be obtained using a technique known as linear programming (LP), also known as linear optimization. A particular type of mathematical programming is linear programming. Formally speaking, linear programming is a method for optimising a linear objective function under the constraints of linear equality as well as linear inequality. Convex polytopes, a set defined as that of the intersection of a finite number of half spaces, which are defined by a linear inequality, make up its feasible region. A real-valued affine (linear) function defined on the this polyhedron serves as its objective function. If there is a point in the polytope in which this function does have the smallest (or largest) value, a linear programming algorithm locates it.

Let the cost of 1 slice of pizza be x and cost of 1 soda be y.

Now,

Richard bought 3 slices of pizza and 2 sodas for $8.75

Therefore, [tex]3x+2y=8.75[/tex]

Jordan bought 2 slices of pizza and 4 sodas for $8.50

Therefore, [tex]2x+4y=8.50[/tex]

Solving above equations, we get         [tex]x=2.25[/tex] and [tex]y= 1[/tex].

Cost of 1 slice of pizza and 3 sodas = 2.25 + 3*1

                                                           = 2.25 +  3

                                                            = 5.25

Hence, Cost of 1 slice of pizza and 3 sodas = $5.25

Substitute the given values into the formula:

[tex]\implies (6, 0)=\left(\dfrac{k-3+3h+4}{2},\dfrac{k-2+1-2h}{2}\right)[/tex]

[tex]\implies (6, 0)=\left(\dfrac{k+3h+1}{2},\dfrac{k-2h-1}{2}\right)[/tex]

Equating the x-values to create an expression for k:

[tex]\implies \dfrac{k+3h+1}{2}=6[/tex]

[tex]\implies k+3h+1=12[/tex]

[tex]\implies k+3h=11[/tex]

[tex]\implies k=11-3h[/tex]

Equating the y-values to create an expression for k:

[tex]\implies k-2h-1=0[/tex]

[tex]\implies k-2h=1[/tex]

[tex]\implies k=2h+1[/tex]

Equate the expressions for k and solve for h:
