Answer:     " 1 lb ,  14 oz. " .

_________________________________________________

Step-by-step explanation:

_________________________________________________

Note the exact conversion:    " 16 oz.  =   1 lb.  " .

→  {that is:  " 16 ounces  =  1 pound " .}.

_________________________________________________

  30 oz. * ( 1 lb / 16 oz). =  [tex]\frac{30}{16}[/tex]  lbs. ;

                                      = (30/2) / (16/2)   lbs.

                                      =  (15 / 8) lbs.  ;

_________________________________________________

       1

8 ┌ 15

    -  8                            

        7  ;              

______________________

The answer is equal to:  " 1  7/8  lbs. " .  

           →   (1 lb)  + (7/8) (lb).  ;

______________________

 →  (7/8) lb.   =  how many "oz." ??

_______________________

Note the exact conversion:   " 1 lb.   =   16 oz.  " .

_______________________

 →   [tex]\frac{7 lb}{8}[/tex] * [tex]\frac{16 oz}{1 lb}[/tex]  ;

                    =  [tex]\frac{7}{8} * \frac{16}{1}[/tex]  oz.   ;

 →  The "8" cancels to a "1" ; and the "16" cancels to a "2" ;

                   →  {since:  " {16 ÷ 8 = 2 } " ;  

             and:   {since:  " {8 ÷ 8 = 1 } " .

_______________________________________________

 →  So we can rewrite as:  

_______________________________________________                  

                  →  [tex]\frac{7}{1} *  \frac{2}{1}[/tex]  oz. ;

                         =  { 7  *  2 }  oz.  ;

                         =   14  oz.

_______________________________________________

→  So:        

_______________________________________________  

 →   " 30 oz. "  =  " (1 lb)  + (7/8) lb.  "  ;

                        =  "  1 lb. + 14 oz. "  ;

                        =  " 1 lb ,  14 oz. " .

_______________________________________________

        →  The answer is:  " 1 lb ,  14 oz. " .

_______________________________________________

Let us check our answer:

  →   Does:     " 1 lb.  +   14 oz. = ?  30 oz. ? " ;

_______________________________________________

Note the exact conversion:  " 1 lb.  =  16 oz. " .

_______________________________________________

  →   Does:  " 16 oz.   +   14 oz.   =  ?   30 oz. ??  " ;

_______________________________________________

  ₁

  16 oz            

+ 14 oz            

  30  oz.

_______________________________________________

→   Does:   " 30 oz.  = ?  30 oz. ? "  ??? ;  →   Yes!

A. 3

Fill in the given values in the formula (h=0, r=48) and solve for t.

... 0 = 48t -16t²

... 0 = 16t(3 -t)

This is true for t = 0 and for t = 3.

The ball will take 3 seconds to hit the ground.

Answer:

A.3

Step-by-step explanation:

Answer:

f(x) and g(x) have the same x-intercepts (is not true)

Step-by-step explanation:

g(x) is a reflection across the y-axis and a horizontal compression of f(x). In general those transformations will move the x-intercepts. (The y-intercept and the number of x-intercepts will remain unchanged.)

_____

Comment on the question/answer

f(x) = x^3 is a 3rd degree polynomial. When transformed to g(x) = -8x^2, its only x-intercept (x=0) remains the same. The answer above will not apply in any instance where the only x-intercept is on the line of reflection. (The question is flawed in that it does not make any exception for such functions.)

Answer:

71.79 degrees

Step-by-step explanation:

The cosine is (adjacent side to angle) / (hypotenuse)

so the cosine of x = 5/16

to get x you multiply cosine by its inverse

(cos^-1 x)(cos x) = (cos^-1 x)(5/16)

= 71.79 degrees

Answer:

The correct answer is:    [C]:

"Answer choices:

[A]:  "The figure is a square..." ;

________________________________________________

[B]:   "The figure is a rectangle..." ;  AND :

________________________________________________

[D]: "The figure is a square..."  .

Answer:

option no D

Step-by-step explanation:

AS it given that it is a random generator

so it will generate random integers between 1 and 3

so

possible sample space = {1,2,3}

Total no of out comes = 3

Estimated probability that 3 will occur will be obtained by dividing total no of outcomes with total no of possible events to occur

as the occurrence of event is only 1

so

Estimated probability = 1 /3 = 0.33333

Now

The experiment is performed

total outcomes = 14

Total no of like able events that 3 occurred = 4

Actual probability = 4 / 14

                             = 0.2857

Difference between actual and estimated probability is = 0.3333-0.2857

                                                                                            =0.0421

                                                                                           ≅0.04

which is option D

Final answer:

The actual probability of a 3 being generated is 1/3, and the estimated probability from the given sequence is 4/14. The difference between the two probabilities is roughly 0.05, which corresponds to answer choice C.

Explanation:

The question refers to the probability of a random generator selecting the number 3 from a set of integers ranging from 1 to 3, where each number has an equal chance of being selected. The actual probability of the random generator selecting a 3 is 1/3, as there are three possible outcomes and each is equally likely. To find the estimated probability, we can look at the frequency of the number 3 in the provided set of generated numbers: (1 2 3 3 3 2 2 1 1 1 2 3 1 1). In this set, there are 4 occurrences of the number 3 out of 14 total numbers. Therefore, the estimated probability is 4/14 or approximately 0.2857. The difference between the estimated and actual probabilities is 0.3333 (actual) - 0.2857 (estimated) = 0.0476. When rounded to two decimal places, the difference is approximately 0.05. Thus, the correct answer to the question would be C. 0.05.

Answer:

2.3 × 10^18

Step-by-step explanation:

Your formula tells you ...

... F × (1.3 × 10^-8) = 3.0 × 10^10

Dividing by the coefficient of F, you have ...

... F = 3.0/1.3 × 10^(10-(-8))

... F ≈ 2.3 × 10^18

1. A line has only a length dimension. It has no width or height. It is a one-dimensional object.

2. Points on the same line are collinear. On the same plane, they are called coplanar. Coordinates locate a point relative to some measurement reference.

So with this system of equations, I will be using the elimination method. With the two equations, add them together and you will get:

[tex]2x=6[/tex]

Since the y-variable has been eliminated, we can solve for x. With this, divide both sides by 2:

[tex]x=3[/tex]

Now that we know the value of x, substitute it into either equation to solve for y:

[tex]3+y=2\\y=-1\\\\3-y=4\\-y=1\\y=-1[/tex]

In (x,y) form, your answer is (3,-1).

Answer:

x=3, y=-1

Step-by-step explanation:

x+y = 2  

x -y =4  

I will use elimination to eliminate the variable y.  Add the two equations together.

x+y = 2  

x -y =4  

-------------

2x = 6

Divide each side by 2

2x/2 = 6/2

x = 3

But we still don't know y

x+y =2

Substitute x=3 into the equation

3+y =2

Subtract 3 from each side

3-3 +y =2-3

y =-1

Answer:

[tex]24p[/tex]

Step-by-step explanation:

There's a very useful pattern in factoring and multiplying binomials called a difference of squares, and it looks like this:

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

We can use this difference of squares to factor the expression we've been given, setting [tex]x=2p+3[/tex] and [tex]y=2p-3[/tex] to obtain the expression

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

tackling each of the multiplicands on the right:

[tex](2p+3)+(2p-3)=2p+2p+3-3=4p[/tex] (Left)

[tex](2p+3)-(2p-3)=2p-2p+3-(-3)=3+3=6[/tex] (Right)

This simplifies the expression on the right of (1) to [tex]4p\cdot6[/tex], or simply [tex]24p[/tex].

Answer:

D. $5.37

Step-by-step explanation:

We need to figure out how much grapes cost per pound

Change the mixed number to an improper fraction

7 1/5 = (5*7+1) /5 = 36/5

$12.89 / 36/5

Copy dot flip

12.89 * 5/36 = 1.79 per lb

If we are purchasing 3 pounds, we will multiply by 3

3 lbs * $1.79 / lb = $5.37

7 months

After Carter makes his $500 payment, the balance on the loan is -1596.37. We want to find the number of months (m) such that ...

... -1596.37 +250m ≥ 0

... m ≥ 1596.37/250 . . . . add 1596.37, divide by the coefficient of m

... m ≥ 6.4

The least number of months that is more than 6.4 is 7 months.

_____

Comment on this answer

Carter's loan balance may also be affected by interest charged on the loan amount. We don't expect those charges to be so high as to require an additional month's payment.

Answer:

96°

Step-by-step explanation:

ΔKLM is isosceles, so base angle KML will be half the supplement of ∠MLK, or ...

.... ∠KML = (180° -48°)/2 = 66°

ΔKJM is also isosceles, so base angle JMK will be the same measure as ∠JKM, 30°.

∠JML = ∠JMK + ∠KML = 30° +66°

∠JML = 96°

All of them

A. 3/7 ≈ 0.43

B. 4/9 ≈ 0.44

C. 33/50 = 0.66

D. 9/14 ≈ 0.64

All of the above numbers are 0.66 or less.

Answer:

The correct answer is 5.34

Step-by-step explanation:

you can double check this by multiplying .6 and 8.9

Answer:

x = 5.34

Step-by-step explanation:

x/ .6 = 8.9

We want to solve for x, which means we want x by itself.

Multiply each side by .6

x/ .6  * .6= 8.9 * .6

x = 5.34

[tex]\frac{x}{8} + 19 = 30[/tex] - subtract 19 from both sides

[tex]\frac{x}{8} = 11[/tex] - multiply both sides by 8

[tex]x = 88[/tex]

In this equation, x = 88.

Answer:

14z + 16 is your perimeter

Step-by-step explanation:

To solve the perimeter, add all sides together. Note that in a rectangle, the opposite sides are congruent and parallel to each other.

Let Perimter = p

p = 2(4z + 3) + 2(3z + 5)

Simplify. Distribute the numbers.

2(4z + 3) = 8z + 6

2(3z + 5) = 6z + 10

Simplify. Combine like terms

p = 8z + 6 + 6z + 10

p = 14z + 16

14z + 16 is your perimeter

Answer:

f=0.02b

Step-by-step explanation:

So we want to figure out the fee (f) therefore our answer will be in terms of f=(something).  Now since the fee is 2% and 2% is decimals is 2÷100=0.02  then:

f=0.02b

Meaning that the fee is 2% of the balance (b).

Answer:

26 most years; 27 some years

Step-by-step explanation:

1 day out of 14 is 1/14 of the number of days in a year.

The number of days in a year depends on the year or years you're talking about. In all cases, there are not an integer number of weeks in a year, so days are left over. 365/14 = 26 1/14.

For example, if you're concerned with every other Monday, most years, there will be 26 of them, but every few years there will be 27. Over a period of 800 years, there will be exactly 71 years with 27 days of interest instead of 26. 800 is not divisible by 71, so the spacing will be uneven.

Answer:

Additive identity.

Step-by-step explanation:

The zero is the additive identity. It is so named because when you add 0 to anything, you leave the unchanged.  To give you a better idea about what this is, the multiplication identity is 1

One times anything does not change anything's value. 1 * 33 = 33. 33 is left unchanged.

Answer:

93 °F

Step-by-step explanation:

At 7 am, the temperature was 55 °F + 2×7 °F = 69 °F.

At 10 am, the temperature was 69 °F + 3×8 °F = 93 °F.

Since the temperature was constant until 3 pm, it was 93 °F at noon.

Answer:

$13

Step-by-step explanation:

$26,555 ÷ 36 = 737.6388889 ≈ $738 per month

36 × 738 = $26,568

= $13

Answer:

$13 will be overpaid after 36 months if payments are rounded of to nearest whole number dollar.

Step-by-step explanation:

We are given the following in the question:

Total cost of car = $26,555

Number of equal installments made = 36

Payment of 1 installment =

[tex]\displaystyle\frac{\text{Toatl cost}}{\text{Number of installments}} = \frac{26555}{36} = 737.6389\$[/tex]

Rounding of to nearest whole number, payment of one installment =  $738

Value of 36 installments of $738 each =

[tex]36\times 738 = 26568\$[/tex]

Money overpaid after 6 months =

[tex]26568 - 26555 = 13\$[/tex]

Thus, $13 will be overpaid after 36 months if payments are rounded of to nearest whole number dollar.
