Mixed number is the combination of the whole number and the proper fraction. One is integer and other is fraction in a mixed number. When you multiply a mixed number by another mixed number the product is equal to the another mixed number. For exact same mixed number, when you multiply a mixed number by one  number the product is equal to the mixed number.

Mixed number is the combination of the whole number and the proper fraction. One is integer and other is fraction in a mixed number. As it is the combination of two types of number thus it is known as mixed number.

Mixed number are used to count the whole and part of a thing together.

For example five and a half of a thing can be written as,

[tex]5+\dfrac{1}{2} =5\dfrac{1}{2}[/tex]

Now when a mixed number is multiplied by the another mixed number the product of both is a another mixed number.

For example let multiply 2 and a half with 3 and a half. The result is,

[tex]2\dfrac{3}{2} \times3\dfrac{3}{2} =\dfrac{7}{2} \times \dfrac{9}{2}[/tex]

[tex]2\dfrac{3}{2} \times3\dfrac{3}{2} =\dfrac{63}{4}[/tex]

[tex]2\dfrac{3}{2} \times3\dfrac{3}{2} =15\dfrac{3}{4}[/tex]

Thus when you multiply a mixed number by another mixed number the product is equal to the another mixed number.

If the product should be equal to the given mixed number thus it need to be multiplied by the one. Thus when you multiply a mixed number by one  number the product is equal to the mixed number.

Answer:

B, D, D, B, C

Step-by-step explanation:

1) The part of the equation that tells us the graph would open downward would be B, the negative coefficient of [tex]x^{2}[/tex].

We know this because, if we reorganize the equation into the standard form  y = mx + b, we get y = -(x²) + 1. This means that for any value we substitute for x, y will always be negative. The answer is B.

2) To find the zeroes of this function, we just have to see which answer makes the function, well, zero.

We have the equation y = (-16t - 2) (t - 1)

We set the equation equal to zero like this:

0 = (-16t - 2) (t - 1)

We also know that anything multiplied by zero will equal zero, so:

0 = (-16t - 2) and 0 = (t - 1)

Now we just solve for t in both equations:

0 = -16t - 2

-16t = 2

t = 2/-16 or -1/8

0 = t - 1

t = 1

So our answer will be D.

3) This time, we are given the same equation but the variable t represents time and y represents the height.

The zeroes are when y = 0, so the zeroes (which are 1 and -1/8 from the last problem) mean that the height is also at zero (which is the ground).

Furthermore, time cannot be negative, so the correct answer choice would be D.

4) We are given the same equation and story problem, but instead we are asked to find the height when the ball was thrown. In other words, we need to find the y-intercept.

The y-intercept is when t = 0, so:

y = (-16t - 2) (t - 1)

y = (-16(0) - 2) (0 - 1)

y = (-2) (-1)

y = 2

So, the correct answer is B, 2 feet.

5) This problem is a simple theoretical question. We know that the constant c will represent the vertical translation or y-intercept, so the correct answer is C.

Answer:

A = 22.5 sq units

Step-by-step explanation:

A = 1/2h(sum of bases)

A = 1/2(5)(3+6)

A = 2.5(9)

A = 22.5

The triangle EFG is an isosceles triangle as side EF is congruent to side EG.

In this question we have a triangle whose vertices are known. We need to define the figure according to the congruency among its sides. Two sides are congruent when both have the same length. There are three kinds of triangles:

Sides are formed each pair of vertices. The length of each side can be found by means of Pythagorean theorem:

l = √[(Δx)² + (Δy)²]

First, write the locations of the vertices:

E(x, y) = (1, 4), F(x, y) = (5, 4), G(x, y) = (1, 0)

Second, determine the length of every side of the triangle:

EF = √[(5 - 1)² + (4 - 4)²]

EF = 4

FG = √[(1 - 5)² + (0 - 4)²]

FG = √[4² + (- 4)²]

FG = 4√2

EG = √[(1 - 1)² + (0 - 4)²]

EG = 4

By direct comparison, we conclude that the triangle EFG is an isosceles triangle.

Answer:

angle B = 127.5 degrees

angle D = 127.5 degrees

Step-by-step explanation:

The above figure is of a kite.

the non-vertex angles( I. e angle B and angle D) are congruent to each other in a kite.

Let angle B be x.

therefore, angle D is also x. ......(as they are congruent to each other)

The sum of all the angles in a quadrilateral is 360 degrees.

therefore,

65 + 40 + x + x = 360

105 + 2x = 360

2x = 360 - 105

2x = 255

x = 255/2

x = 127.5

therefore, angle B and Angle D are 127.5 degrees each.

Answer:

x = 9

Step-by-step explanation:

(3x-20)/9 = 56/72

72(3x-20) = 9(56)

216x-1440 = 504

add 1440 to each side

216x = 1944

divide both sides by 216

x = 9

Answer:

9

Step-by-step explanation:

If you draw a segment parallel to a side of triangle that intersects two sides of the triangle, that segment divides the intersected sides into segments of proportional lengths.

9/72 = (3x - 20)/56

1/8 = (3x - 20)/56

3x - 20 = 1/8 * 56

3x - 20 = 7

3x = 27

x = 9

6x - 5y = 12

Put the value of y in 2nd equation

6x - 5( -2x +20 ) = 12

6x +10x -40 = 12

16x = 12 +40

16x = 52

x = 13/4
