Step-by-step explanation:

Please mark brainliest...

multiply each value of the C. by 1,000 to get the # of C.s divide the # of C.s / T.s this gives you C.s per T.Convert to ratio formatthere is on average 15 to 20 C.s per T.5250/273 = 14.0756250/325 = 19.2307250/377 = 19.2309250/273 = 19.230    6250  =  y  

             377        572

    2.  multiply both sides by 572

    3. 572 .  6250 = y

                   377

   4. divide known pair

572 x 19.230 = y

   5. solve for y

   6. y = 10999.56

   7. divide y value by 1000

   8. 10.99956

Answer:

4[tex]\frac{7}{12}[/tex]

Step-by-step explanation:

Give make the fractions improper first!

3[tex]\frac{1}{4}[/tex] -> [tex]\frac{13}{4}[/tex]

1[tex]\frac{1}{3}[/tex] -> [tex]\frac{4}{3}[/tex]

Now give them the same denominator, making it easy to solve.

[tex]\frac{13(3)}{4(3)}[/tex] -> [tex]\frac{39}{12}[/tex]

[tex]\frac{4(4)}{3(4)}[/tex] - >[tex]\frac{16}{12}[/tex]

now add!

[tex]\frac{55}{12}[/tex] - > 4[tex]\frac{7}{12}[/tex]

Need help, What is the volume? and can you explain how you got the answer :)

Answers

Answer/Explanation:

To find out the volume of this Rectangular Prism you have to multiply by length * width * height.

So what's [tex]3\frac{3}{8} *2?[/tex] It's [tex]\frac{27}{4}[/tex], and since there are [tex]2[/tex] sides of the same length * width * height, so [tex]\frac{27}{4} *2=\frac{27}{2}[/tex].

So now the upper and bottom face of the Rectangular Prism are figured out.

Now we have to do [tex]2*2[/tex], so what's [tex]2*2?[/tex] It's [tex]4[/tex]. Now like before there are [tex]2[/tex] sides of the same length * width * height, so we do [tex]4*2[/tex], and what's [tex]4*2?[/tex] It's [tex]8[/tex], now we add them together which is [tex]\frac{27}{2} +8=\frac{43}{2}[/tex], or we can say the answer is [tex]21.5[/tex] in decimal form.

So the Volume = [tex]21.5[/tex] or [tex]\frac{43}{2}[/tex]

Wait it's actually [tex]\frac{27}{4} *4[/tex] which is [tex]27[/tex], so then we actually do [tex]27+8[/tex], which is [tex]35[/tex].

SO IT'S ACTUALLY 35
The answer is 35. Hope this helps:)

Answer:

27. C

28. D

Step-by-step explanation:

The average of all grades in his fencing class, including the upcoming one, (all grades summed up divided by the amount of grades) must be equal to 86 (percent), hence C is the right answer for 27.

Solving this equation gives:

[tex]\frac{75+88+62+100+x}{5} = 86\\325 + x = 86 \cdot 5\\x = 430 - 325 = 105[/tex]

So D is the right answer for 28.

27 is c And 28 is d.
