prim numbers between 30 and 60 are
31, 37, 41, 43, 47, 53, and 59

Answer:

The three prime numbers are, 31, 37, and 41.

How I got the answer:

1. 31 is a prime number: 31 x 1 = 31  

                                        1 x 31 = 31

2. 37 is a prime number: 37 x 1 = 37

                                          1 x 37 = 37

Chalene wants to cut her hair but is a little nervous. She decides to cut it off slowly so she can get used to it as it gets shorter. Right now, her is is 11.5 inches past her shoulders. She decides to cut an inch and a half off her hair every week. Write an expression to describe the length of her hair in relationship to her shoulders.

Answers

Final answer:

The length of Chalene's hair in relation to her shoulders can be described using the expression:

Length of hair = 11.5 - 1.5n,

where 'n' represents the number of weeks. Each week, Chalene cuts 1.5 inches off her hair.

Explanation:

To describe the length of Chalene's hair in relation to her shoulders, we can use the expression:

Length of hair = 11.5 - 1.5n

where 'n' represents the number of weeks.

Each week, Chalene cuts 1.5 inches off her hair, so we subtract 1.5 from the previous length to get the new length.

For example, after 1 week, the length of her hair will be 11.5 - 1.5(1) = 10 inches past her shoulders.

Shaylyn measured her house as 5 meters tall. Which of these is an equivalent measurement?a. 0.3 milesb. 7.3 yardsc. 16.4 feetd. 27.2 inches

Answers

To solve this equation, you would convert 5 meters to miles, yards, feet, and inches. 

5 meters = 0.00310686 miles (doesn't match answer given)
5 meters = 5.46807 yards (doesn't match answer given)
5 meters = 16.4 feet (matches answer given)
5 meters = 196.85 inches (doesn't match answer given)

So, your answer would be C. 16.4 feet

Solve the following proportion for x 6/7 = 48/x

Answers

The answer is:  " x = 56 " .
____________________________
Given :  " 6/7 = 48/x ;  Solve for "x" ;

Method 1):   "Cross multiply" ;

6x = 7 * 48 ;

6x = 336 ;

Divide each side by "6" ;  as follows:
__________________________________
 6x / 6 = 336 / 6 ;
______________________________________
to get:
______________________________________
   x = 56 .
______________________________________

Method 2):   Given:  " 6/7 = 48/x " ; Solve for "x" ;
______________________________________
  Cross-multiply:
______________________________________
                    6x = 7 * 48 ;
______________________________________
  Now, divide EACH SIDE of the equation by "6" ;  
    to isolate "x" on one side of the equation; 
 & to solve for "x" ;
______________________________________
                      6x = 7 * 48 ;
______________________________________
Divide EACH side of the equation by "6" :
______________________________________

 [tex] \frac{6x}{6} [/tex]  = [tex] \frac{7*48}{6} [/tex]  ;
______________________________________
On the "left-hand side" of the equation, the "6 's " cancel out to "1" ; 

{since:  (6÷6=1) ; & we are left with "x" on the left-hand side of the equation} ;

On the "right-hand side" of the equation; the "48" in the denominator

  cancels out to an "8" ; and the "6" cancels to a "1" ; 

{since: (48÷6=8); & (6÷6=1) ; and the denominator gets "eliminated"; 

{since the denominator is equal to "1" ;

    & any value (including the numerator),  divided by "1" (the denominator),

  is equal to that same value (the numerator);

so there is no need for the "denominator".
________________________________________
We can rewrite the equation as:

        x = 7 * 8 ; and solve;    7 * 8 = 56 ;

          →  x = 56 .
_____________________________________

Method 3):  Given:  " 6/7 = 48/x " ; Solve for "x" ;
____________________________________________________
    →  6/7 = 48/x ;  

   → Comparing the "numerators" ;  " [ 6 * (what value?)  = 48 ?] " ??

                                                       [ (48 ÷ 6 = (what value?) ] ??
                                         
                                                        48 ÷ 6 = 8 /

So:  "6/7" = (6*8) / (7*8) = 48/56 = 48/ x ??  ;
   
                                                          → x = 56 .

A bread making machine costs $99.The ingredients to make a one pound loaf of bread costs $0.45 .At store, you pay 2.19 for the same size loaf of bread.How many whole loaves of bread will you have to make in order for the cost of the machine and ingredients to be less than the cost of buying an equivalent Amount of bread at the store.

Answers

Hi there! I can help! So we already know that $99 is the cost of the bread making machine. Buying the first loaf of bread would be $2.19 and the total cost of machine and loaf is $99.45. For two loafs of bread is $4.38 store bough and $99.90 hand made. Three slices of bread bought from the store would be $6.57 and $100.35 hand made. If you keep doing the same pattern, the answer will eventually come up, but even after 50 loaves of store bought bread, the total would still be $109.50 and $121.50 for bread and hand made total costs. On 57th slice of bread, buying from the store would total $124.83 and having it hand made would be $124.65. You would have to make 57 whole loaves of bread in order for the cost of the machine and ingredients to be less than the cost of buying the same size loaves from the store.
Final answer:

To determine the number of loaves of bread needed to make the cost of the machine and ingredients less than buying bread at the store, set up an inequality and solve for 'x'. With the given values, you would need to make at least 5 whole loaves of bread.

Explanation:

To determine how many loaves of bread will need to be made for the cost of the machine and ingredients to be less than the cost of buying bread at the store, we need to compare the costs of making bread and buying bread.

The cost of making a one pound loaf of bread using the machine and ingredients is $0.45. The cost of buying a one pound loaf of bread at the store is $2.19.

Let's assume the cost of making each whole loaf of bread is $0.45. We can set up an inequality to represent the situation:

0.45x < 2.19

Where 'x' is the number of loaves of bread that need to be made.

To solve for 'x', we divide both sides of the inequality by 0.45:

x > 2.19/0.45

Using a calculator, we find that x > 4.87. Rounded up, this means you would need to make at least 5 whole loaves of bread in order for the cost of the machine and ingredients to be less than buying bread at the store.

A coral reef grows 0.13 m every week how much does it grow in 12 weeks

Answers

Final answer:

To find out how much a coral reef grows in 12 weeks, with a weekly growth of 0.13 m, multiply the growth rate by the number of weeks, resulting in a total growth of 1.56 m.

Explanation:

If a coral reef grows 0.13 m every week, to find out how much it grows in 12 weeks, we simply need to multiply the weekly growth rate by the number of weeks:

Weekly growth rate = 0.13 m

Number of weeks = 12

Therefore, the total growth over 12 weeks is:

0.13 m/week × 12 weeks = 1.56 meters.

In 12 weeks, the coral reef grows by a total of 1.56 meters.

What values are needed to make each expression a perfect square trinomial?
x2 + 4x +_____________
x2 – 10x + ____________

Answers

Answer:

Part a) [tex]x^{2}+4x+4[/tex]

Part b) [tex]x^{2}-10x+25[/tex]

Step-by-step explanation:

we know that

A perfect square trinomial is equal to

[tex](x+a)^{2} =x^{2}+2ax+a^{2}[/tex]

Part a) we have

[tex]x^{2}+4x[/tex]

Compare with the formula of a perfect square trinomial

[tex]x^{2}+4x=x^{2}+2ax+a^{2}[/tex]

so

[tex]4x=2ax[/tex]

[tex]4=2a[/tex]

[tex]a=2[/tex]

therefore

[tex](x+a)^{2} =(x+2)^{2}=x^{2}+4x+4[/tex]

Part b) we have

[tex]x^{2}-10x[/tex]

Compare with the formula of a perfect square trinomial

[tex]x^{2}-10x=x^{2}+2ax+a^{2}[/tex]

so

[tex]-10x=2ax[/tex]

[tex]-10=2a[/tex]

[tex]a=-5[/tex]

therefore

[tex](x+a)^{2} =(x-5)^{2}=x^{2}-10x+25[/tex]

The values are needed to make each expression a perfect square trinomial x^2 + 4x + 4 and x^2 – 10x + 25.

What is a perfect square?

A perfect square is a number system that can be expressed as the

square of a given number from the same system.

A. [tex]x^{2} +4x+4[/tex]

A perfect square trinomial is

[tex](x+a)^2 = x^2 + 2ax + a^2[/tex]

Compare with the formula of a perfect square trinomial

4x = 2ax

4 = 2a

a = 2

Therefore, [tex](x+a)^2 = (x+2)^2 = x^{2} +4x+4[/tex]

B. [tex]x^{2} -10x + 25[/tex]

A perfect square trinomial is

[tex](x+a)^2 = x^2 + 2ax + a^2[/tex]

Compare with the formula of a perfect square trinomial

-10x = 2ax

-10 = 2a

a = -5

Therefore, [tex](x+a)^2 = (x-5)^2 = x^{2} -10x+25[/tex].

A train travels at a constant speed of 75 mi/h. The function f(x) = 75x gives the distance that the train travels in x hours. Graph this function and give its domain and range.

Answers

Final answer:

f(x) = 75x represents the distance covered by a train traveling at a constant speed of 75 mi/h. The graph is a line with a constant slope of 75, originating from (0,0). The domain and range of the function are both all non-negative real values ([0, +∞)).

Explanation:

To graph the function f(x) = 75x, where x represents time in hours and f(x) represents distance in miles, we construct a simple 2D graph. In this case, the graph will be a straight line sloped upward, starting from the origin (0,0), since the time and distance both start from zero. The slope of the line corresponds to the speed of the train, 75 mi/h, indicating that the train covers 75 miles each hour.

The domain, or possible x-values, of this function are all non-negative real numbers since time cannot be negative. In mathematical terms, this is [0, +∞). The range, or possible f(x)-values, are also all non-negative real numbers as the distance covered also cannot be negative. So, the range is also [0, +∞).
