you found a recipe which calls for 1/2 pound of chicken per person, if 4 pounds of chicken costs $8, what is the cost per person for the recipe you are using?

Answers

9514 1404 393

Answer:

  $1 per person

Step-by-step explanation:

The per-person cost (x) can be found from the proportion ...

  x/(0.5 lb) = $8/(4 lb)

Multiplying by 0.5 gives ...

  x = (0.5 lb) × ($8 /(4 lb)) = $1 . . . . . . units of lb cancel

The cost per person will be $1.

if f(x)=2x^2-5 and g(x)=5x+7 g(x)=

Answers

☆Answer :

Answer in the picture.

A function assigns the values. The value of f(g(x)) is 50x² + 140x + 93.

What is a Function?

A function assigns the value of each element of one set to the other specific element of another set.

Given the value of f(x)=2x²-5 and g(x)=5x+7, therefore, the value of f(g(x)) can be written as,

f(g(x)) = 2(5x+7)²-5

f(g(x)) = 2(25x²+49+70x)-5

f(g(x)) = 50x² + 98 + 140x - 5

f(g(x)) = 50x² + 140x + 93

Hence, the value of f(g(x)) is 50x² + 140x + 93.

Use elimination to solve.
3y-6x=7
-4y-3x=9

Answers

Answer:

x = -5/3, y = -1 or [tex](-\frac{5}{3}, -1)[/tex]

Step-by-step explanation:

Solving systems of linear equations using process of elimination involves eliminating one of the variables (and its coefficient) in order to solve the other variable either through addition or subtraction. However, there may be other mathematical operations necessary before one of the variables can be eliminated.  

Equation 1:   3y - 6x = 7

Equation 2:  -4y - 3x = 9          

Step 1:  Multiply Equation 2 by -2:

(-2)(-4y - 3x) = 9 (-2)

8y + 6x = -18

Step 2: Add "8y + 6x = -18" to Equation 1:

  8y + 6x = -18

+ 3y - 6x = 7

11y = -11

Step 3: Divide both sides by 11 to solve for y:

[tex]\frac{11y}{11} = \frac{-11}{11}[/tex]

y = -1

Step 4: Substitute y = -1 into Equation 2 to solve for x:

-4(-1) - 3x = 9      

    4 - 3x = 9

Step 5: Subtract 4 from both sides:

    4 - 4 - 3x = 9 - 4

   - 3x = 5

Step 6: Divide both sides by -3 to solve for x:

[tex]\frac{-3x}{-3} = \frac{5}{-3}[/tex]

[tex]x = - \frac{5}{3}[/tex]

Verify whether the values for x and y are correct by substituting their values into both equations:

x = -5/3, y = -1

Equation 1:   3y - 6x = 7

[tex]3(-1) - 6(-\frac{5}{3}) = 7[/tex]  

-3 + 10 = 7

7 = 7 (True statement).

Equation 2:  -4y - 3x = 9          

-4(-1) - 3 (-5/3)  = 9          

[tex]-4(-1) - 3(-\frac{5}{3}) = 9[/tex]

4 + 5 = 9

9 = 9  (True statement).

Therefore, x = -5/3 and y = -1 are the solutions to the given systems of linear equations.  

Write the ratio in simplest form. 10 seconds to 5 min

Answers

Answer:

10:5

Step-by-step explanation:

The simplest form of the ratio 10 seconds to 5 min will be;

⇒ 1 : 30

What is mean by Ratio?

A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y.

Where, x and y are individual amount of two quantities.

And, Total quantity gives after combine as x + y.

Given that;

The ratio is,

⇒ 10 seconds to 5 minutes.

Now,

Since, The ratio of two numbers has always same units.

So, We change 5 minutes into seconds as;

Since, 1 minutes = 60 seconds

Hence, 5 minutes = 5 x 60 seconds

                            = 300 seconds

Thus, The ratio becomes,

⇒ 10 seconds to 300 seconds

⇒ 10 : 300

⇒ 10 / 300

⇒ 1 / 30

⇒ 1 : 30

Thus, The simplest form of the ratio 10 seconds to 5 min will be;

⇒ 1 : 30

4 boys weighed themselves in different pairs and alone. The weights of the pairs were 110kg, 112 kg, 113kg, 118kg, 121 kg, and the weight of one pair was lost. The total weight of the 4 boys was 230kg. What was the lost weight?

Answers

Answer:

116

Step-by-step explanation:

you can use variables

a+b=110

a+c=112

a+d=113

b+c=118

b+d=121

add up the weights and you get 574 kg (you need to find c+d)

3a+3b+2c+2d=574

a+b+c+d = 230 as given then you multiply by 3 so you can cancel out 3a and 3b and subtract 690-574 because we multiplied by 3

you are left with c+d=116

The number of coupons x used by a customer in a grocery store is a random variable with the probability density function f(x) = 4x + 3 27 , [0, 3] Find the expected number of coupons a customer will use.

Answers

Applying the integral formula, it is found that the expected number of coupons a customer will use is of 1.83.

The probability density function is given by:

[tex]f(x) = \frac{4x + 3}{27}, [0,3][/tex]

The integral formula for the expected value is:

[tex]E(x) = \int_0^3 xf(x) dx[/tex]

Hence, applying the formula for f(x) given in this problem, the expected number of coupons a customer will use is:

[tex]E(x) = \int_0^3 \frac{4x^2}{27} + \frac{x}{9} dx[/tex]

[tex]E(x) = \frac{4x^3}{81} + \frac{x^2}{18}|_{x = 0}^{x = 3}[/tex]

[tex]E(x) = 1.83[/tex]

The expected number of coupons a customer will use is of 1.83.

Step-by-step explanation:

The interior angle at E is (180 -4x), the supplement of the exterior angle there, 4x. The sum of angles 2x and (180-4x) will be equal to 6x, because alternate interior angles at transversal BE are congruent:

  2x +(180 -4x) = 6x
