Change the mixed numbers from mixed numbers into fractions, so you would have:
16/3 + 22/5
Now to add these two together, they have to have the same denominator. To do that, multiply 16/3*5/5 and 22/5*3/3 and your new terms would be:
80/15 + 66/15
Now you can add the numerators together:
146/15
and simplify for your answer:
9 11/15

What is the volume of this sphere?
Natasha_Volkova [10]

Answer:

Option c. 11,488.21 cm3

Step-by-step explanation:

<u><em>The picture of the question in the attached figure</em></u>

we know that

The volume of the sphere is equal to

V=\frac{4}{3}\pi r^{3}

we have

r=28/2=14\ cm ---> the radius is half the diameter

\pi =3.14

substitute

V=\frac{4}{3}(3.14)(14)^{3}

V=11,488.21\ cm^3

Steven has $25 dollars to spend. He spent $10.81, including tax, to buy a new DVD. He needs to save $10.00 but he wants to buy a
Yuliya22 [10]

(25 - 10.81) - 1.38p = 10

p = package of peanuts  

25 - 10.81 = 14.19

14.19 - 1.38p = 10

Subtract 14.19 from each side

10 - 14.19 = -4.19

-1.38p = -4.19

Divide both sides by -1.38

p = 3 (roughly, but because you can only buy the whole package, this is the amount you can buy)

He can buy a maximum of 3 packages of peanuts.

Write and solve a system of equations. Be sure to label the variables. The sum of two numbers is fourteen. Two times the first n
goldfiish [28.3K]

Answer:

First number = 33, Second number = -19

Step-by-step explanation:

We can use F to represent the first number and S to represent the second number.

Our two equations then are F + S = 14 and 2F + 3S = 9

We can use substitution:

F+S = 14\\2F+3S=9\\F=14-S\\2(14-S)+3S=9\\28-2S+3S=9\\28+S=9\\S=-19\\\\F-19=14\\F=33
