Answer:

x = 9

Step-by-step explanation:

We need to find the value of x if the polygons in each pair are similar.

As they are similar, the ratio of their sides are equal.

The sides of first polygon are 6,12 and 4.8. On the other hand, the sides of second polygon are (2x-9) and 18.

So,

[tex]\dfrac{6}{2x-9}=\dfrac{12}{18}\\\\\dfrac{6}{2x-9}=\dfrac{2}{3}\\\\\dfrac{3}{2x-9}=\dfrac{1}{3}\\\\x=9[/tex]

So, the value of x  is equal to 9.

Answer:

Yes

Answer:

40 children went on the cruise.

Step-by-step explanation:

This question can be solved by a system of equations.

I am going to say that:

x is the number of adults on the cruise

y is the number of children on the cruise.

57 tickets were sold:

This means that [tex]x + y = 57[/tex], and since we want the number of children y, [tex]x = 57 - y[/tex]

Each adult had to pay $22 for the cruise and each child had to pay $10. The company's total receipts were $774.

This means that:

[tex]22x + 10y = 774[/tex]

Since [tex]x = 57 - y[/tex]

[tex]22(57 - y) + 10y = 774[/tex]

[tex]1254 - 22y + 10y = 774[/tex]

[tex]12y = 480[/tex]

[tex]y = \frac{480}{12}[/tex]

[tex]y = 40[/tex]

40 children went on the cruise.

Answer:

[tex] x = \dfrac{5}{2} \pm {\dfrac{\sqrt{57}}{2} [/tex]

Step-by-step explanation:

[tex] x^2 - 5x = 8 [/tex]

[tex] x^2 - 5x + \dfrac{25}{4} = 8 + \dfrac{25}{4} [/tex]

[tex] (x - \dfrac{5}{2})^2 = \dfrac{57}{4} [/tex]

[tex] x - \dfrac{5}{2} = \pm \sqrt{\frac{57}{4}} [/tex]

[tex] x = \dfrac{5}{2} \pm {\dfrac{\sqrt{57}}{2} [/tex]

Answer:

[tex]b2 = 3[/tex]

Answer:

j(x)=a(x+9)(x-2)

j(x)=1(x+9)(x-2) < final answer

F- test

Step-by-step explanation:

Testing the hypothesis about the equality of  k (k>2) population means

Test statistic F is used to find the whether there is no difference in the average age of each group.

Test statistic to be used

F= Between Mean Square/ Within Mean Square

F= s1²/s2²   where s1 and s2 are  independent unbiased estimates of the variance and their values do not differ greatly.

Which have  v1= k-1 and v2= n-k degrees  of freedom

The analysis of variance F -t est is always a one tailed test with rejection region located in the right tail of the F- distribution.

Mrs. Lopez need to sew a piece of cloth whose length be 150.72 inches.

A circumference gives the length around a circular object, it is the perimeter used for the circular objects.

Given that a circular tablecloth has a radius of 24 inches, we need to find the length around it,

So, the length around a circular object is its circumference,

We know that circumference of the circular object = π × diameter,

Diameter = 2 × radius = 48 inches.

So, the length around the circular cloth = π × 48

= 3.14 × 48
= 150.72

Hence Mrs. Lopez need to sew a piece of cloth whose length be 150.72 inches.
