Answer:

28. x=6  29. x=15  30. -56/5  31. -3   32. -10   33.  9.6

Step-by-step explanation:

The statement "y varies inversely as x" means that there is a constant (a number that doesn't change)  k  so that

[tex]y=\frac{k}{x}[/tex]

28. y = 12 when x = 3, so [tex]12=\frac{k}{3} \Rightarrow k=(12)(3)=36[/tex].  Now that you know the value of  k  (in THIS problem!), plug in 6 for  y  to find  x.

[tex]6=\frac{36}{x}\\6x=36\\x=6[/tex]

All these problems work the same way.

29. [tex]5=\frac{k}{6} \Rightarrow 5(6)=k \Rightarrow k=30[/tex]  Then, [tex]2=\frac{30}{x} \Rightarrow 2x = 30 \Rightarrow x=15.[/tex]

30.  

 [tex]4=\frac{k}{14} \Rightarrow (4)(14)=k \Rightarrow k=56\\-5=\frac{56}{x} \Rightarrow -5x=56 \Rightarrow x = -\frac{56}{5}[/tex]

31.

[tex]9=\frac{k}{9} \Rightarrow 81=k\\\\y=\frac{81}{-27}=-3[/tex]

= 3 × 4

= 3 × 2²

x = 1

= 3 × 15 = 5x

= 45 /5 = x

equation for surface area: A=5 /4tan(54°)a2+5a /2h2+(atan(54°) /2)2

5 /4·tan(54°)·72+5·7 /2·7.972+(7·tan(54°) /2)2

round to nearest hundredth: 247.21

Answer:

f(10) = 3

Step-by-step explanation:

If f(x) = [tex]-\frac{3}{5} x + 9[/tex] , in order to find the result for f(10) we just need to substitute 10 instead of x and we will get...

[tex]f(x) = -\frac{3}{5} x + 9\\\\f(10) = -\frac{3}{5} (10) + 9\\f(10) = - 6 + 9\\f(10) = 3[/tex]

Answer:

12.2

Step-by-step explanation:

Answer:

12.2

Step-by-step explanation:

the tenth is shown       12.23

                                          I

                                          I

                                          I

after locating the tenth, we follow rounding principles. if the number to the right is 0-4, the place value you are looking at stays the same (which happens in our case). If the number to the right is 5+, we round the number to the left up so if it was 12.27, it would be 12.3

Answer:

Regular pizza: £5

Small pizza: £4

Step-by-step explanation:

Let x = regular pizza

Let y = small pizza

6x + 12y = 78

2x + 3y = 22

I'm going to use elimination method to solve for y

6x + 12 y = 78

-3(2x + 3y = 22) = -6x -9y = -66

Eliminate the x

3y = 12

Divide both sides by 3

3y/3 = 12/3

y = 4

Substitute the y in one of the original equations

2x + 3(4) = 22

2x + 12 = 22

Subtract both side by 12

2x + 12 - 12 = 22 - 12

2x = 10

Divide both sides by 2 to solve for x

2x/2 = 10/2

x = 5

Answer:

small  $3.4   regular $6.2

Step-by-step explanation:

2r +3s = 22.6

6r *12s = 78

Multiply the first  by -3

-6r -9s = -67.8

6r +12 s = 78

Add both (6r will be cancelled)

   3s = 10.2

s = 3.4   small = 3.4   (3 small = 10.2)  

2r +10.2 = 22.6

2r =  12.4

r = 6.2

Answer:

The Réaumur scale also known as the "octogesimal division", is a temperature scale in which the freezing and boiling points of water are set to 0 and 80 degrees respectively. The scale is named after René Antoine Ferchault de Réaumur, who first proposed something similar in 1730.

Fahrenheit is a thermodynamic temperature scale, where the freezing point of water is 32 degrees Fahrenheit (°F) and the boiling point 212°F (at standard atmospheric pressure). This puts the boiling and freezing points of water exactly 180 degrees apart. Therefore, a degree on the Fahrenheit scale is 1/180 of the interval between the freezing point and the boiling point of water. Absolute zero is defined as -459.67°F.

Step-by-step explanation:

first you divide 5,500 by 485(5,500/485), then you will get 11.34, and since you cannot buy half of something, you will have to round down to 11. then you multiply 11 by 15 (11 X 15) and you will get 165, so then you go back and subtract 165 from 5,500 (5,500-165)  and there is your answer (5335).

Answer:

the answer is 5335.

Answer:

x= -4 and  x=6

Step-by-step explanation:

what ever x is that makes (x+4) = 0, so -4

and (x+6)=0, so -6. In other words, solve for x in the factored equations (the equation here is factored) and just solve for zero

Answer:

x = -3, 0, 2

Step-by-step explanation:

=> x³ + x² - 6x = 0

=> x(x² + x - 6) = 0

=> x² + x - 6 = 0 or x = 0

=> x² + 3x - 2x - 6 = 0 or x = 0

=> x(x + 3) - 2(x + 3) = 0 or x = 0

=> (x + 3)(x - 2) = 0 or x = 0

=> x = - 3 or x = 2 or x = 0

Answer:

Step-by-step explanation:

The congruence theorems or postulates that could be given as reasons why triangles ABC and LMN are congruent are: LL, HL and SAS

From the figure, we can see that the hypotenuse of both triangles are congruent; this represents the HL theorem

Also, the acute legs of both triangles are congruent;

This represents the LL theorem

One angle is between two congruent sides in both triangles.

This represents the SAS theorem

Hence, the congruence theorems or postulates that could be used are: LL, HL and SAS

Answer:

P'(7, 5)

Step-by-step explanation:

Rule for the transformation of a point [tex]R_{x=1}(P)[/tex] defines,

Reflection of a point P(x, y) about a line, x = 1 which is parallel to y-axis.

Line x = 1 works like a mirror so the distance between the line and the image point will be equal to the distance between the line and the original point.

Distance between the line and a point (-1, 5) = 4

Therefore, distance between the line and the image point = 4

Coordinates of the image point will be,
