Answer:

20/9

Step-by-step explanation:

16/9 * 5/4

4/9 * 5

20/9

The quotient of dividing the given fractions is 20/9.

Given that, 1 7/9=16/9 and 4/5.

From the given fractions we need to divide 16/9  by 4/5.

A fraction represents a part of a whole or, more generally, any number of equal parts.

The first step to dividing fractions is to find the reciprocal (reverse the numerator and denominator) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. Finally, simplify the fractions if needed.

Now, 16/9÷4/5

Change ÷ to × and reciprocate 4/5 to 5/4.

Then, 16/9÷4/5=16/9×5/4=20/9

Therefore, the quotient of the given fraction is 20/9.

Answer:

[tex]r=0.75 = 75[/tex]%

Step-by-step explanation:

Equation of General exponential growth function is

[tex]f(x)=a(1+r)^{x}[/tex] ------------ (1)

Where a is initial value x is time and r is growth rate

Given function can be written in following form

[tex]f(x)=2500(1+0.75)^{x}[/tex] ------------ (2)

After comparing (1) and (2) we can conclude that

[tex]r=0.75 = 75[/tex]%

In ΔVWX, w = 780 cm, ∠X =21° and ∠W=146°. Find the length of x, to the nearest 10th of a centimeter.

Answer:

499.9cm

Step-by-step explanation:

We solve for length x using the Sine rule

w/ sin W = x /sin X

Cross Multiply

x × sin W = w × sin X

x = w × sin X/ sin W

x = 780 × sin 21°/ sin 146°

x = 499.88 cm

Approximately to nearest tenth = 499.9cm

Answer:

3x^2 + 3  -->  6, 15, 30, 51

2x^2 - 1    -->  1, 7, 17, 31

x^2 + 2     -->  3, 6, 11, 18

Step-by-step explanation:

Let's start with the first equation; 3x^2 + 3

Substitute 1 (the first digit in a sequence) for x.

3(1^2) + 3

3(1) + 3

3 + 3 = 6

3(2^2) + 3 Then the second digit.

3(4) + 3

12 + 3 = 15

Since the two numbers we have so far are 6 and 15, there is only one sequence this could match. 6, 15, 30, 51.

2(1^2) - 1

2(1) - 1

2 - 1 = 1

This equation represents 1, 7, 17, 31.

These same steps apply to the other equation as well.

1^2 + 2, then 2^2 + 2, then 2^2 + 2, and so on. (But we don't need to do extra work to figure that out.)

Step-by-step explanation:

The cucumber were sold at $224.

A single unit's value may be determined from the values of multiple units, and multiple units' values can be determined from the values of single units using the unitary technique. We typically utilise this technique for math computations.

This approach allows us to calculate both the value of many units from the value of one unit and the value of many units from the value of one unit.

Given:

area of garden = 56 square feet.

1 cucumber = 72 square inches = 0.5 square feet

Number of cucumbers

= 56 / 0.5

= 112 cucumbers

Price for each cucumber = $2

So, price for 112 cucumber = 112 x 2

                                            = $224

Hence, the cucumber were sold at $224.

Consider the below figure attached with this question.

[tex]\angle ABO=20^\circ[/tex]

[tex]\angle ACO=30^\circ[/tex]

To find:

The value of x.

Solution:

Draw a line segment OA as shown below.

In triangle ABO,

[tex]OA=OB[/tex]      [Radii of same circle]

[tex]m\angle BAO=m\angle ABO=20^\circ[/tex]        [Base angles of an isosceles triangle]

In triangle ACO,

[tex]OA=OC[/tex]      [Radii of same circle]

[tex]m\angle CAO=m\angle ACO=30^\circ[/tex]        [Base angles of an isosceles triangle]

Now,

[tex]m\angle BAC=m\angle BAO+m\angle CAO[/tex]

[tex]m\angle BAC=20^\circ+30^\circ[/tex]

[tex]m\angle BAC=50^\circ[/tex]

Central angle is always twice of angle subtended by two points on the circle.

[tex]m\angle BOC=2\times m\angle BAC[/tex]

[tex]x=2\times (50^\circ)[/tex]

[tex]x=100^\circ[/tex]

Therefore, the value of x is 100°.

The Fourth coordinate is (4, 3) and 35 unit squared.

A pair of numbers called coordinates are used to locate a point or a form in a two-dimensional plane. The x-coordinate and the y-coordinate are two numbers that define a point's location on a 2D plane.

Given:

From the graph the fourth coordinate of rectangle is

At x axis = 4
