Tyler needs to complete this table for his consumer science class. He knows that 1 tablespoon contains 3 teaspoons and that 1 cup contains 16 tablespoons. What belongs in cell A?

Answer:

b) 8.

Step-by-step explanation:

The tens digit must be 2, 4, 6 or 8.

The units digit must be 0 or 5 ( as the 2 digit number must be divisible by 5).

So they are:

20, 25, 40, 45, 60, 65 , 80 and 85.

Answer:The tens digit must be 2, 4, 6 or 8.

The units digit must be 0 or 5 ( as the 2 digit number must be divisible by 5).

So they are:

Answer:

1.   [tex]TV = 68[/tex]

2.  [tex]x = 7[/tex]

3.   [tex]x = 21[/tex]

4.    [tex]CD = 8[/tex]

Step-by-step explanation:

Solving (1):

Given

[tex]RT = 63[/tex]

[tex]RV = 131[/tex]

Required

Determine TV

To solve TV, we make use of the following formula;

[tex]RV = RT + TV[/tex]

Substitute values for RT and RV

[tex]131 = 63 + TV[/tex]

Make TV the subject of formula

[tex]TV = 131 - 63[/tex]

[tex]TV = 68[/tex]

Solving (2):

Given

[tex]MN = 26[/tex]

[tex]MP = x + 4[/tex]

[tex]PN = 2x + 1[/tex]

Required

FInd x

To solve x, we make use of the following formula;

[tex]MN = MP + PN[/tex]

Substitute values for MP, MN and NP

[tex]26 =x + 4 + 2x + 1[/tex]

Collect Like Terms

[tex]2x + x = 26 - 4 -1[/tex]

[tex]3x = 21[/tex]

Divide both sides by 3

[tex]x = 7[/tex]

Solving (3):

Given

[tex]HM = 4x - 12[/tex]

[tex]MJ = 3x + 9[/tex]

Required

Find x

Since M is the midpoint;

[tex]HM = MJ[/tex]

This gives

[tex]4x - 12 = 3x + 9[/tex]

Collect Like Terms

[tex]4x - 3x = 12 + 9[/tex]

[tex]x = 21[/tex]

Solving (4):

Given

[tex]CE = 6x + 2[/tex]

[tex]DE = 2x + 4[/tex]

Required

FInd CD

Since D is the midpoint;

[tex]CD= DE[/tex]

and

[tex]CE = CD + DE[/tex]

Substitute CD for DE

[tex]CE = DE + DE[/tex]

[tex]CE = 2DE[/tex]

Substitute values for CE and DE

[tex]6x + 2 = 2(2x + 4)[/tex]

Open Bracket

[tex]6x + 2 = 4x + 8[/tex]

Collect Like Terms

[tex]6x - 4x = 8 - 2[/tex]

[tex]2x = 6[/tex]

Divide both sides by 2

[tex]x = 3[/tex]

Recall that;

[tex]CD= DE[/tex]

So;

[tex]CD = 2x + 4[/tex]

Substitute 2 for x

[tex]CD = 2 * 2 + 4[/tex]

[tex]CD = 4 + 4[/tex]

[tex]CD = 8[/tex]

Answer:

x=-6

For PA:  78-29=49

For AQ:  48+3=51

Step-by-step explanation:

The line is from left to right PAQ

It says PQ is 100 which is the whole line

PA +AQ is PQ so that means:

-13x-29-8x+3=100

-21x-26=100

-21x=126

x=-6

Plug in the x values to PA and AQ

For PA:  78-29=49

For AQ:  48+3=51

Answer: 93

Step-by-step explanation:

To solve this problem, we need to use the order of operations, or PEMDAS.

Parenthesis

Exponent

Multiply

Divide

Add

Subtract

For multiply/divide and add/subtract, you don't necessarily go in that specific order. You go from left to right, depending on what comes first. For example, if division comes before multiply, you would divide first, then multiply. Same goes for add/subtract.

9²+3×(9-5)²/4                          [solve parenthesis]

9²+3×(4)²/4                              [solve exponent]

81+3×16/4                                [solve multiply or divide, whichever comes first]

81+12                                        [solve add or subtract, whichever comes first]

93

Now, we know that 93 is our final answer.

Answer:

All real numbers

Step-by-step explanation:

Solution set of -2(x +3) = -2x -6 is all x ∈R (real numbers).

" Equation is defined as when two algebraic expression which are related with the sign of equality."

According to the question,

Given,

-2(x + 3) = -2x - 6

Open the brackets of the equation we get,

-2(x) + (-2)(3) = -2x - 6

⇒ -2x - 6 = -2x - 6

Add 6 on both the sides of the equation we get,

-2x = -2x

Divide by -2 of the equation both sides

x = x                                 _____(1)

Add (-x) both the sides we get,

0 = 0                                 _____(2)

From (1) and (2) we conclude ,

Solution is true for all  the real values of x.

Hence, solution set of -2(x +3) = -2x -6 is all x ∈R (real numbers).

Answer:

12 boxes an hour

Step-by-step explanation:

If Adsila made 9 boxes an hour for 6 hours,she made 54 boxes (9*6=54). Take how many she made away from the total (126-54=72). If Carlos made 72 boxes in 6 hours, divide 72 by 6 to get 12 (72/6=12). Carlos made 12 boxes an hour.

Answer:

The answer is below

Step-by-step explanation:

a) Food I contains 3 g of carbohydrate and food II 5 g of carbohydrate. x is the number of ounce of food I while y is the number of ounce of food II.

Therefore, the amount of carbohydrate in food 1 is 3x while that of food II is 5y. Since the blend contains  exactly 73 g of carbohydrate, the total number of carbohydrate in both food I and food II is 73 g. Hence:

3x + 5y = 73                    (1)

Food I contains 2 g of protein and food II 3 g of carbohydrate. Therefore, the amount of protein in food 1 is 2x while that of food II is 3y. Since the blend contains  exactly 46 g of protein, the total number of protein in both food I and food II is 46 g. Hence:

2x + 3y = 46                   (2)

Using geogebra to Sketch the graphs of both equations.

b) The point of intersection is gotten from the graph, this gives x = 11, y = 8.

The point of intersection shows the amount of food I and food II that give the required amount of protein and carbohydrate.

11 ounce of food I and 8 ounce of food II would produce the required amount of protein and carbohydrate

(-1,-4)

Step-by-step explanation:

(-5,-3) if we're moving four units right on the x axis, it would be a bigger number near the center.  Think of it as adding -5 and 4, which would get you -1 for x (-1,x)

Now to get y, we would basically do the same thing except if it's going down, it would be a negative.  We would add both -1 and -3 together to get -4, hence the answer, (-1,-4)

Answer:

The test statistics is  [tex]t  =  -1.727[/tex]

Step-by-step explanation:

From the question we are told that

The data given is  

   330 620 1870 2410 4620 6396 7822 81028309 12882 14419 16092 18384 20916 23812 25814

 The population mean is  [tex]\mu  =  14400[/tex]

    The  sample  size is  n =  16

  The  null hypothesis is  [tex]\mu \le  14400[/tex]

    The  alternative hypothesis is  [tex]H_a  :  \mu > 14400[/tex]

The sample mean is mathematically evaluated as

  [tex]\= x  =  \frac{\sum x_i}{n}[/tex]

So

   [tex]\= x  =  \frac{330+ 620+ 1870 +2410+ 4620+ 6396+ 7822+ 8102+8309+ 12882+ 14419+ 16092+ 18384 +20916+ 23812+ 25814 }{16}[/tex]

=>  [tex]\= x = 10799.9[/tex]

The  standard deviation is mathematically represented as

      [tex]\sigma =\sqrt{\frac{ \sum (x_i - \=x)^2}{n}} [/tex]

So

[tex]\sigma =\sqrt{\frac{(330- 10799.9)^2 + (620- 10799.9)^2+ (1870- 10799.9)^2 +(2410- 10799.9)^2 + (4620- 10799.9)^2 +(6396- 10799.9)^2 +(7822- 10799.9)^2 }{16}}  \ ..[/tex]

   [tex]..\sqrt{ \frac{(8102 - 10799.9)^2 +(8309 - 10799.9)^2 + (12882 - 10799.9)^2 + (14419 - 10799.9)^2 + (16092 - 10799.9)^2 + (18384 - 10799.9)^2 +(20916 - 10799.9)^2  }{16}} \ ...[/tex]

  [tex]\ ... \sqrt{\frac{(23812 - 10799.9)^2 +(25814 - 10799.9)^2 }{16}}[/tex]

=>  [tex]\sigma  =  8340[/tex]

  Generally the test statistic is mathematically represented as

  [tex]t =  \frac{10799.9- 14400}{ \frac{8340}{\sqrt{16} } }[/tex]

[tex]t  =  -1.727[/tex]

From the z-table  the p-value is  

     [tex]p-value  = P(Z > t) =  P(Z >  -1.727) =  0.95792[/tex]

 From the values obtained we see that

        [tex]p-value  >  \alpha[/tex]  so we fail to reject the null hypothesis

Answer:

The answer is D.

Step-by-step explanation:

We have to apply Discriminant Law. When a quadratic equation, ax² + bx + c = 0 has equal roots so the discriminant will be 0. Then, you have to substitute the values into the formula :

[tex]D = {b}^{2} - 4ac[/tex]

[tex]let \: D = 0 ,a = 2,b = k,c = k[/tex]

[tex]0 = {k}^{2} - 4(2)(k)[/tex]

[tex] {k}^{2} - 8k = 0[/tex]

[tex]k(k - 8) = 0[/tex]

[tex]k = 0[/tex]

[tex]k - 8 = 0[/tex]

[tex]k = 8[/tex]

Answer:

n - 6 = 5 * ( n + 2 ) ; n = -4

Step-by-step explanation:

For this problem, we will use the words to create an equation.  The left hand side of the equation will be the difference of a number and 6 and the right hand side of the equation will be 5 times the sum of the number and 2.  Hence, we can build the equation:

n - 6 = 5 * ( n + 2 )

If we wanted, we can solve the equation for the number, n.

n - 6 = 5 * ( n + 2 )

n - 6 = 5 * n + 5 * 2

n - 6 = 5n + 10

-16 = 4n

-4 = n

Thus, we have found the missing number to be negative four.
