8 0

Given parameters:

        1.        -\frac{7}{8}  + \frac{1}{4}  

 

         -\frac{7}{8}  + \frac{1}{4}; find the LCM = 8

 

             =    \frac{-7  +  2 }{8}        

             =     \frac{-5}{8}

   

       2.   -\frac{12}{5}  + 15.3  

            Make the fraction decimal;

             -\frac{12}{5}   = -2.4

            So;

                        -2.4 + 15.3  = 12.9

Find the slant height l of the cone given the surface area S.
Oduvanchick [21]

9514 1404 393

Answer:

  15 cm

Step-by-step explanation:

The formula for the surface area of the cone is ...

  A = πr² +πrL =  πr(r +L)

The radius of this cone is half its diameter so is (12 cm)/2 = 6 cm. Then the slant height L can be found from ...

  126π cm² = π(6 cm)(6 cm +L)

  21 cm = 6 cm +L . . . . . . . . . . . . . . divide by 6π cm

  15 cm = L . . . . . . . . . . . . . . . . subtract 6 cm

The slant height is 15 centimeters.

GrogVix [38]

Answer:

35 plants

Step-by-step explanation:

For this case we can make the following rule of three:

4 gallons --------------> 14 plants

x --------------------------> 35 plants

From here, we clear the value of x.

We have then:

therefore, 10 gallons are needed to irrigate 35 plants.

Answer:

it will take 10 gallons to water 35 plants

Gage is building a model rocket for a science fair project. He attaches a nosecone to a cylindrical body to form the rocket's fu
denpristay [2]

Answer:

305.78 in2

Step-by-step explanation:

The rocket has two parts: one is a cylinder and the other is a cone.

To find the total volume of the rocket, we need to find firstly the volume of each part.

The cylinder has a radius of 2 inches and a height of 2*12 + 5 - 7 = 22 inches, so its volume is:

V1 = pi * r^2 * h = pi * 2^2 * 22 = 276.46 in2

The cone has a radius of 2 inches and a height of 7 inches, so its volume is:

V2 = (1/3) * pi * r^2 * h = (1/3) * pi * 2^2 * 7 = 29.32 in2

Then, we have that the volume of the rocket is:

V = V1 + V2 = 276.46 + 29.32 = 305.78 in2
