Starting on a platform 2 feet above sea level, dive down to a location that is 20 feet below sea level, and then rise 8 feet.
Starting 2 feet below sea level, dive down 20 more feet, and then rise to a location that is 8 feet below sea level.
Starting 2 feet below sea level, dive down 18 more feet, and then rise to a location that is 8 feet below sea level.

Answer:

45/4

Step-by-step explanation:

We can interpret the question to have two equation which can be solve simultaneously

a+b=7------------(1)

a-b=2------------(2)

From eqn(2) make a subject of formula

a=2+b--------(3)

Substitute the (3) into eqn(1)

a+b=7------------(1)

2+b+b=7

2b=7-2

2b=5

b=5/2

From equation (3) substitute value of b to find a

a=2+b--------(3)

a= 2+5/2

a=9/2

Then What is the value of a x b ?

9/2× 5/2

=45/4

Answer:

11 1/4

Step-by-step explanation:

a+b=7

a-b=2

adding equations gives us 2a=9  so a= 9/2

b= 7- 9/2= 14-9/2=5/2

therefore a x b= 9/2 x 5/2 =45/4

45/4 in a mixed number is 11 1/4

Answer: 15 feets

Step-by-step explanation:

Given that :

Area of square shaped lawn = 224.9 ft²

Measurement closest to side length of the lawn :

Since the length is square shaped ;

Area of square formula = a²; where a = side length of the square

Area = a²

224.9 ft² = a²

Take the square root of both sides

√224.9ft² = √a²

14.996666 ft = a

a = 14.996666 ft

a = 15 ft

Hence, the side length of the lawn is closest to 15 feets

Answer:

first equation and second equation

Step-by-step explanation:

it is more easier because both of them have the same y

Answer:

Use equation (1) and equation(2) and eliminate 4y+z

Step-by-step explanation:

3x-4y+z=-5     ...(1)

6x-4y+z=1        ...(2)

x+y+z=6          ...(3)

First, you find the equation that you can use the elimination method on;

there are multiples of them.

However, I would use equation (1) and equation(2) and eliminate 4y+z :

 3x-4y+z=-5

- 6x-4y+z=1  

         -3x=-6

            x=2

As you can see, both the terms with y and z are eliminated in one step, exposing the variable x.

From here is just my advice:

There are multiple ways for you to answer this question. In math, the process may sometimes not matter if the answer was correct. Nevertheless, you should try finding one way that fits you or makes it easier to solve. I personally think that how I have been trying this helped me later when math got more complicated. (Also, it was fun for me to find another way that I was not taught of)

GOOD LUCK!! and I HOPE THIS HELPS YOU!!!!

Step-by-step explanation:

Answer:

60.96cm

Step-by-step explanation:

So if 12 beads=4 inches

        72 beads=72 beads*4 inch

                            12 beads

That will give you 24inches. inch-cm multiply by 2.54cm

=60.96cm of rope

The alternative hypothesis is [tex]H_a : p > 0.9[/tex] and it is found the statistic is 1.04 Test the claim with 5% significance level. is the test left right or two tailed and what is the p value

Answer:

    This a right tailed test

  The p-value is   p-value  = 0.14917

Step-by-step explanation:

From the question we are told that

   The alternative hypothesis is [tex]H_a : p > 0.9[/tex]

   The test statistics is  [tex]z = 1.04[/tex]

    The level of significance is  [tex]\alpha = 0.05[/tex]

Generally this a right tailed test because from the alternative hypothesis p > 0.9 i.e due to the greater than sign signifying that test will be focusing on the right tail of the normal curve

From the z table the area under the normal curve to the right corresponding to 1.04 is  

     P( Z>  1.04 )  = 0.14917

Generally the p-value is mathematically represented as

      p-value  =  P( Z>  1.04 )  = 0.14917

The remainder when 73,847 is divided by 43 will be 16.

What is Division method?

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.

For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

The mathematical expression is,

''73,847 is divided by 43''

Now,

Find the remainder when 73,847 is divided by 43 as;

43 ) 73,847 (1717

    - 43

   --------

      308

    - 301

     -------

          74

          43

        -------

          317

        - 301

         ------

           16

Thus, The remainder when 73,847 is divided by 43 will be 16.

Answer: I’ll explain it in simpler terms for you. A proportional relationship is one in which two quantities vary directly with each other. Ratios are proportional if they represent the same relationship. One way to see if two ratios are proportional is to write them as fractions and then reduce them. If the reduced fractions are the same, your ratios are proportional. An example of a proportional relationship is simple interest, tax, markups and markdowns, gratuities and commissions, fees, percent increase and decrease, percent error. Hope this helps! :D
