Solve for the missing side round to the nearest 10th (look at image)
SIZIF [17.4K]

Answer:

14.3

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem

a^2 + b^2 = c^2   where a and b are the legs and c is the hypotenuse

14^2 + 3^2 = c^2

196 + 9 = c^2

205 = c^2

Take the square root of each side

sqrt(205) = sqrt(c^2)

14.31782106 = c

Rounding to the nearest tenth

14.3 = c

Can u guys help me with this problem
netineya [11]

Answer:

-0.7 or -\frac{7}{10}

Step-by-step explanation:

-0.75-(-\frac{2}{5})+0.4+(-\frac{3}{4})

The opposite of -\frac{2}{5} is \frac{2}{5}

-0.75 + \frac{2}{5} +0.4 - \frac{3}{4}

Convert decimal number −0.75 to fraction -\frac{75}{100}.

​Reduce the fraction-\frac{75}{100} to lowest terms by extracting and canceling out 25.

-\frac{3}{4} + \frac{2}{5}+0.4-\frac{3}{4}

Least common multiple of 4 and 5 is 20. Convert -\frac{3}{4} and \frac{2}{5} to fractions with denominator 20.

-\frac{15}{20}+ \frac{8}{20} +0.4 - \frac{3}{4}

Since -\frac{15}{20} and \frac{8}{20} have the same denominator, add them by adding their numerators.

\frac{-15 +8}{20} +0.4-\frac{3}{4}

Add -15 and 8 to get -7

-\frac{7}{20}+0.4-\frac{3}{4}

Convert decimal number 0.4 to fraction \frac{4}{10}. Reduce the fraction \frac{4}{10} to lowest terms by extracting and canceling out 2.

-\frac{7}{20}+\frac{2}{5}-\frac{3}{4}

Least common multiple of 20 and 5 is 20. Convert -\frac{7}{20} and \frac{2}{5} to fractions with denominator 20.

-\frac{7}{20}+\frac{8}{20}-\frac{3}{4}

Since -\frac{7}{20} and \frac{8}{20} have the same denominator, add them by adding their numerators.

20-7+8-\frac{3}{4}

Add -7 and 8 to get 1.

\frac{1}{20}-\frac{3}{4}

Least common multiple of 20 and 4 is 20. Convert \frac{1}{20} and \frac{3}{4} to fractions with denominator 20.

\frac{1}{20}-\frac{15}{20}

Since \frac{1}{20} and \frac{15}{20} have the same denominator, subtract them by subtracting their numerators.

\frac{1}{20}-15

Subtract 15 from 1 to get -14.

20-14

Reduce the fraction -\frac{14}{20} to lowest terms by extracting and canceling out 2.

-\frac{7}{10} or -0.7

Hope this helps! Brainliest would be much appreciated! Have a great day! :)

There are 12 boys and 15 girls in my classroom. What is the ratio of girls to total students in the classroom?
Anit [1.1K]

I acidently removed the stuff but anyways the answer is 12:27 or 12 to 27

do 12 + 15 = 27, and so 12 to 27 :)

Find the value of x and y in the parallelogram. Explain.
Ray Of Light [21]

x = 26


Because 26-2=24 which would be right because it needs to equal the same size as the other side that is across from it.


y = 11


Because it’s the same size as the bottom side, which is also the side across from it.



This is true because a parallelogram has 2 sets of parallel side!!!



I hope this helps! :)

a survey conducted in a school showed that 65% of the students walked to school. The remaining students took buses to school. Th
Feliz [49]
I fear that there is an error copying your assignment.  
65% of the students walked.  Are all of the other students on buses?  Are there both public buses AND private buses?
Assuming that you need to know BOTH kinds of buses, try this:

65% of the students walked, so since 100% - 65% = 35% then this means that 35% of the students were on buses.
Since we know that there are 360 more walkers than bus riders, then one equation we know is:  65% of S = 360 + 35% of S  (let S = total # of students)
              .65 S     = 360 + .35 S
           <u> - .35 S   </u>  =     <u>   - .35 S</u>      Subtract .35 S from both sides
             <u> .30  S   </u> = <u> 360</u>                 Divide both sides by .30 (or .3)
                .30           .30
                      S   =  1,200  so we know that this is the total number of students, but that is not what was asked.  
They want to know how many are on buses and specifically how many are on public buses, if I read this correctly.
   Since the walkers = 65% of 1,2000 and we know of means TIMES, then
                                  .65 (1,200) =  780 walkers
 1,200 total students minus 780 walkers = 420 bus riders

Now, if there is not a misprint and we really have to figure out the public bus riders as compared to the private bus riders, then remember the ratio from above in the question:   4 bus: 3 public buses
Now if I read this right, that means that 3/4ths of the bus riders were on public buses
so 3/4 of 420 means 3/4 times 420  = 3 times 105 = 315 public bus riders (which coincidentally leaves 105 private bus riders, but since they are private we don't know much about them.  Ha-Ha..... I made a lame joke.)

So your answer is 315 public bus riders
