Determine if the two triangles are congruent. If they are, state how you know.

Answer:

1 is inequality

replace the value were _2.

Answer:

84 tiles

Step-by-step explanation:

Given that :

Figure 2 = 8 tiles

Figure 5 = 14 tiles

Growth rate :

(Figure 5 - figure 2)x= 14 - 8

3x = 6

x = 6/3

x = 2

(Figure 40 - figure 2) = 38 * x

Initial number of tiles + 38x

8 + 38(2)

8 + 76

= 84

Figure 40 = 84 tiles

Given:

The equations of a system of equations are

[tex]y=-2x^2+3x-1[/tex]

[tex]x+y=-1[/tex]

To find:

The solution of the given system of equations.

Solution:

We have,

[tex]y=-2x^2+3x-1[/tex]           ...(i)

[tex]x+y=-1[/tex]                      ...(ii)

Using (i) and (ii), we get

[tex]x+(-2x^2+3x-1)=-1[/tex]

[tex]x-2x^2+3x-1+1=0[/tex]

[tex]-2x^2+4x=0[/tex]

Taking out the common factors.

[tex]2x(-x+2)=0[/tex]

Using zero product property,we get

[tex]2x=0[/tex] and [tex]-x+2=0[/tex]

[tex]x=0[/tex] and [tex]2=x[/tex]

For x=0, we have

[tex]0+y=-1[/tex]

[tex]y=-1[/tex]

For x=2, we have

[tex]2+y=-1[/tex]

[tex]y=-1-2[/tex]

[tex]y=-3[/tex]

Therefore, the two solutions of the given system of equations are (0,-1) and (2,-3).

Step-by-step explanation:

Given data

Cost of dinner= $32

TIp=18%

Let us find the amount of the tip

=18/100*32

=0.18*32

=$5.76

Hence the total amount paid is

=5.76+32

=$37.76

The Tip is

=$5.76

Answer:

A.2 Hours.

B.2 Inches.

Step-by-step explanation:

Its easy,

A. 8 inches = 4 hours, 4 inches = .... hours

4 inches = 8 ÷ 2

Hours: 4 hours ÷ 2 = 2 hours

B. 8 inches = 4 hours, .... inches = 1 hour

1 hour = 4 ÷ 4

Inches: 8 inches ÷ 4 = 2 inches.

Answer:

a) 40 inches

b) No it will not fit inside

Step-by-step explanation:

Angharad is buying a new 50-inch screen TV (remember that TV screens are measured along the diagonal )

a) If it is 30 inches tall, how wide is the screen ?

Diagonal ² = Width² + Height²

Diagonal = 50 inches

Height = 30 inches

50² = Width² + 30²

Width² = 50² - 30²

Width = √50² - 30²

Width = √(1600)

Width = 40 inches

b) Her TV cabinet is 30 inches wide .will the TV fit inside it ?

No it will not fit inside

This is because, the width of the TV is the above calculation is 40 inches. This is wider than the width of the TV cabinet, hence, it won't fit inside

Answer:

x = - 3.75

y = 28.75

Step-by-step explanation:

[tex] \begin{cases} x + y = 25\\\\ 5x + y = 10 \end{cases} [/tex]

Since, x + y = 25

Therefore, y = 25 - x..... (1)

5x + y = 10......(2)

Plug y = 25 - x in equation (2), we find:

5x + 25 - x = 10

5x - x = 10 - 25

4x = - 15

x = - 15/4

x = - 3.75

Plug x = - 3.75 in equation (1), we find:

y = 25 - (- 3.75)

y = 25 + 3.75

y = 28.75

(x, y) = (-3.75, 28.75)

Answer:

B

Step-by-step explanation:

The function's zeroes results in vertical asymptotes. As one is at x = 1 and the other at x = -2, the zeroes must be (x-1) and (x+2), which only B contains in the numerator.

Answer:

868.3%

Step-by-step explanation:

8.683 x 100 =  868.3%

Answer: 868.3%

All you need to do to convert a decimal to a percentage is multiply by 100. In this case we have to multiply 8.683 by 100 which gives us 868.3%

Answer: k = 27

Step-by-step explanation:

Here's the complete question:

Write the word sentence as an equation. Then solve the equation. A number k increased by 7 is 34.

An increase in k simply means that there's an addition. This will be:

k + 7 = 34

k = 34 - 7

k = 27

Therefore, the value of k is 27

Answer:

A=20

Step-by-step explanation:

a+b+c=180

A+A+40+5A=180

7A+40=180

7A=140

/7

A=20

20+(20+40)+20*5=180

20+40=60

60+20=80

20*5-100

100+80=180

Answer:

A=20

Step-by-step explanation:

a+b+c=180

A+A+40+5A=180

7A=140

/7

A=20

20+(20+40)+20*5=180

20+40=60

60+20=80

20*5-100

100+80=180

B is 4x bigger than A

Answer:

35

Step-by-step explanation:

Since you know that a triangle must have a total of 180 degrees and a right triangle is 90 degrees then you just subtract 90 from 180 and you get 90. Then subtract 55 from 90 and you get 35 which is the only possible answer.

Answer:

3.2 + 8.4 /6 equal to 4.6

Step-by-step explanation:

Answer:

B: Using x and y factor results in an expression of greater value than using x and y as terms.

Step-by-step explanation:

For her first expression, x and y are factors;

xy

For her second expression, x and y are written as terms;

x + y

For x and y are both negative integers, then;

-x * -y = xy  ............... 1

-x + (-y) = - x - y

            = - (x + y)  .............. 2

Therefore, the value of x and y factors is greater than that when x and y are as terms. Thus the correct option is B.
