Which number line represents all of the values of x for the equation x2 = 64?

Answers

Answer 1
x^2 = 64
x = + - 8

hope it helps
Answer 2

Answer:

We are asked to find all the values of x on the number line that satisfies the given quadratic equation:

[tex]x^2=64[/tex]

We know that this is a quadratic equation so the number of values that we get on the number line is maximum 2.

on taking the square root on both the side of the equation we obtain:

[tex]x=\pm 8[/tex]

Hence we get two points on the number line.

x=8   and x= -8.

These are the discrete values we did not get any interval of the solution.

This is a Joint variation problem which is solved using the equation y = k*x*z.

Solve for "k" using y=72 when x=6 and z=4.
72 = k*6*4
k = 3

Now put k back into the original equation of y= k*x*z and solve.

y = 3*3*6

suppose you earn $7.25 per hour working part-time for a florist. Write and solve an inequality to find how many full hours you must work to earn at least $125

Answers

7.25x > 125 because x equals amount of hours times 7.25 is greater that 125
Let's say t is the amount of time (in hours) it takes to make $125,
with that out of the way, the keyword "at least" makes it so that you can get 125 or more in t hours.
The inequality is $125<=7.25t.
Now you can use the guess and check method, for this example we'll use t=18 and t=17. 
7.25(18)=$130.5
7.25(17)=$123.25

Therefore, the answer is 18, because 18 gives you a number greater than or equal to $125

In 34 pound of a spice mix, there is 56 cup of cinnamon.
How much cinnamon does the spice mix contain per pound?

5/8 cup

​ 9/10 ​ cup

​ 1 1/9 ​ cups

​ 1 3/5 ​ cups

Answers

Find the unit rate:

56 cups cinnamon
------------------------- = 1.64 cups of cinnamon per pound.
  34 pounts

This result (11/17 cups/lb) does not match any of your 4 answer choices, but is closest to 1 3/5 cups/lb.
Final answer:

To determine the amount of cinnamon per pound of the spice mix, divide the total cups of cinnamon (56) by the total pounds of the mix (34), resulting in approximately 1.647 cups per pound. This equates to 1 3/5 cups of cinnamon per pound, which is the closest option.

Explanation:

The question asks us to calculate how much cinnamon is contained in each pound of a spice mixture if we know that there are 56 cups of cinnamon in 34 pounds of the spice mix. To find the cinnamon content per pound, we'll divide the total number of cups of cinnamon by the total number of pounds of the spice mix.

Here is the calculation:
56 cups cinnamon / 34 pounds spice mix = cups per pound.

Doing the division, we get: 56 / 34 = 1.647 cups, which we need to express as one of the provided options. The nearest option to 1.647 is 1 3/5 cups, or 1.6 cups, when rounded to the nearest fraction.

Therefore, the spice mix contains 1 3/5 cups of cinnamon per pound.

c) 5/6 is a rational number. This is because the quotient is a terminating decimal.

Long division is a technique for dividing two numbers that involves working through the remainder and quotient step-by-step. When dividing a larger number (dividend) by a smaller number (divisor) that is difficult to divide in one step, it is usually utilized.

Until there are no more dividend digits, the procedure entails dividing the dividend by the divisor several times, multiplying the divisor by the quotient gained in each step, removing the product from the partial remainder, and bringing down the next dividend digit.

How can area models be used to solve multiplication problems

Answers

When using an area model, each factor in the multiplication problem is used as a dimension of a rectangle.
Final answer:

Area models can be used to solve multiplication problems by visually representing the multiplication as the area of a rectangle or square. The model is divided into equal-sized sections, with the number of sections representing one factor and the size of each section representing the other factor. The total area of the model gives the product of the two factors.

Sophia needs $47 to go on a field trip. She has saved $11.50. She earns $6.50 per hour cleaning her neighbor's garden, and she earns $5.25 per hour selling cakes at a store. Can Sophia go on the field trip if she works at the garden for 4 hours and at the store for 2 hours?

Answers

47 - 11.50 = $35.50 needs to be earned.

If she works 6 hours:
6.50 x 4 = 26
5.25 x 2 = 10.50

26 + 10.50 = $36.50 how much she would earn by working 6 hours.

when you add the amount of money she would earn for working 6 hours $36.50 plus the money she had already had saved up $11.50 the total amount of money she would have is $48.00

So, yes. She would be able to go on the field trip if she worked at both jobs to 6 hours.

_____________________________________
Explanation:
_____________________________________
1)  "Rename one-eight as a percent". 
  
→  [tex] \frac{1}{8}[/tex] = 1 ÷ 8 = 0.125 ;

→ [tex] \frac{x}{100}[/tex] = 0.125 ;  
        
       →  x = 0.125 * 100 = {move the decimal point in the number, "0.125"; two spaces forward, since we are MULTIPLYING, by "100" (which has 2 zeros); 
       →  x = 12 * 100 = 12.5 .

So:  → [tex] \frac{12.5}{100}[/tex] = 12.5 % ;  since "12.5 % = 12.5/100 "
_____________________________________
Other method:
_____________________________________
     → [tex] \frac{x}{100}[/tex] = [tex] \frac{1}{8}[/tex] ; 

               →  x = 100 * [tex] \frac{1}{8}[/tex] ;

               →  x  = [tex] \frac{100}{1}[/tex] * [tex] \frac{1}{8}[/tex] ;

                         =   [tex] \frac{100*1}{1*8} [/tex] ;

                         =   [tex] \frac{100}{8} [/tex] ;

               →   x  =  12.5 ;

               →   [tex] \frac{x}{100} [/tex] = [tex] \frac{12.5}{100} [/tex] = 12.5% ;

                      → 12.5 % =  [tex] \frac{12.5}{100} [/tex] ; 
                                      =  ?

→ {Take the "12.5" & move the decimal backward TWO (2) places, since we              are "dividing" by "100" (which has 2 "zeros") ;
 
                                     = 0.125 = [tex] \frac{125}{100}[/tex] = [tex] \frac{1}{8} [/tex].
_________________________________________________
2)  "Rename "0.709" as a percent."

===>  [tex] \frac{x}{100} [/tex] = 0.709 ;  

    → x = 0.709 * 100 = ? ;

Note:  Take the "0.709" ; & move the decimal place "2 (TWO)" spaces forward, since are MULTIPLYING by "100" (which has 2 zeros); to get:
    → x = 70.9 ;

    → x = 0.709 * 100 = 70.9  ;

→ [tex] \frac{x}{100} [/tex] =  [tex] \frac{70.9}{100} [/tex] = 70.9% ;
                                            → which is:  Answer choice:  [B] .

    →  70.9% = [tex] \frac{70.9}{100} [/tex] = ?  ; 

     {take the "70.9" ; and move the decimal point backwards TWO (2) decimal places; since we are DIVIDING by "100" (which has "2 (two) zeros") ;

x = [tex] \frac{2}{3} [/tex]*100 ;

    = [tex] \frac{2*100}{3*1} [/tex] ;

    = [tex] \frac{200}{3} [/tex] ;

                                                 or, write as:  66.666666....% ; or, round to:

______________________________________________

One-eighth, when converted to a percent, is 12.5%. The decimal 0.709 is equivalent to 70.9% when converted to a percent. Two-thirds is roughly equivalent to 66.7% after conversion and rounding.

Converting Fractions and Decimals to Percents

To convert a fraction to a percent, you can either first convert it to a decimal or multiply the fraction straightaway by 100. For one-eighth, we multiply 1/8 by 100 to get 12.5%. So one-eighth as a percent is 12.5%.

To rename 0.709 as a percent, you move the decimal point two places to the right or multiply by 100, which gives us 70.9%. Therefore, 0.709 as a percent is 70.9%.

Lastly, two-thirds is equivalent to the decimal 0.666... (repeating). To turn this into a percent, we again multiply by 100, yielding approximately 66.7%, after rounding.
