Answer:

8 feet

Step-by-step explanation:

you have to calculate :(19+2x)(6+2x)=770

you will get X1=8,X2= negetive some value but measurement cant be negative .if you put X=8 you'll find LHS=RHS

Answer:

x= \frac{-25}{4}+\frac{1}{4}  \sqrt{3705}  or  x= \frac{-25}{4} + \frac{-1}{4}\sqrt{3705}

Step-by-step explanation:

So first you need to find the area of the swimming pool:

19*6 = 114

Next you add the area of the swimming pool and the area of the walkway:

114 + 770 = 884

After this you solve for x using this equation:

(19 +2x) * (6 + 2x) = 884

This would normally find the area of the whole swimming pool area and the walkway but because we know that we can use it to solve for x.

The step-by-step is this:

4x^{2} +50x+114=884

4x^2+50x+114-884=884-884

 4x^2+50x+114-884=0

Now we'll use the quadratic formula to simplify it farther:

x= \frac{-(50) + \sqrt{(50)^2-4(4)(-770)}  }{2(4)}

x=\frac{-50 + or - \sqrt{14820} }{8}

x= \frac{-25}{4}+\frac{1}{4}  \sqrt{3705} or x= \frac{-25}{4} + \frac{-1}{4}\sqrt{3705}

Yuk noticed that out of 24 students entering the building at Willowville Elementary School this morning, 8 of them were carrying
nordsb [41]

Answer:

the students that brought a lunch box is 28

Step-by-step explanation:

The computation of the students that brought a lunch box is shown below:

= Entire school students × students that carry a lunch box ÷ entering students

= 84 students × 8 ÷ 24 students

= 28 students

Hence, the students that brought a lunch box is 28

For each of the following studies, say whether you would use a t test for dependent means or a t test for independent means.
Shtirlitz [24]

Answer:

1. T test for independent means

2. T test for dependent means

3. T test for dependent means

Step-by-step explanation:

In number 1, the two groups are unrelated. The first group has 25 subjects and they're all unemployed. The second group has 24 subjects and their employment status is not stated and might not be the same all through. Also, the first group is receiving a new type of job skills program while the second group is taking the standard job skills program.

- The groups in the experiment are unrelated

- The tests in the research are unrelated

- The purpose of the research is unreasonable - the researcher seeks to measure how well all 49 subjects perform on 'a' job skills test! No comparison between the scores or mean scores of the two groups.

In number 2, the researcher uses the same subjects and also measures the same variable but twice. This is a good example of a study where the t test for dependent means can be taken. Same applies in case 3.

Find the value of x.<br> 6<br> 14<br> 8<br> 0<br> 21<br> x = [ ? ]<br> 3x-12
love history [14]

Answer: 7

Step-by-step explanation:

By the angle bisector theorem,

\frac{21}{14}=\frac{3x-12}{6}\\21(6)=14(3x-12)\\126=14(3x-12)\\9=3x-12\\21=3x\\x=\boxed{7}

If x varies directly as y, and x=18 when y=6 find x when y= 10!!!!!!
tensa zangetsu [6.8K]
First thing you need to do is find your k in y = kx

So to do that insert 18 for x and 6 for y and then solve for k
y = kx
6 = k18
6/18 = k18 /18
1 / 3 = k
k = 1 /3
So now that we know what k is we can find x when y = 10. Once again insert the numbers we know. We know k = 1/3 and y = 10 and we need to find x
y = kx
10 = (1/3)x
3* 10 =  3*(1/3)x
30 = x
x = 30
