1. Which of the following is not a linear equation in one variable?
Lorico [155]

\huge \boxed{\mathbb{QUESTION} \downarrow}

Which of the following is not a linear equation in one variable?

a) 33

b) 33(x+y)

c) 33x

d) 33y

\large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}

  • Option <em><u>b) 33 (x + y)</u></em> is not a linear equation in 1 variable.
  • Here, we can see that there are 2 variables used ⇨ x & y. Hence, even though it's a linear equation, it's not in 1 variable.
  • All the other options are in 1 variable or don't have a variable at all.

If the sphere shown above has a radius of 11 units then what is the approximate volume of the sphere
adell [148]

Answer:

Volume of the sphere=5563.58units^3

Step-by-step explanation:

Volume of the sphere= \frac{4}{3} *\pi *r^3

The sphere has given radius(r)= 11 units

Putting the value of the radius in the formula;

     Volume of the sphere:

                                     = \frac{4}{3} *3.14*11*11*11

                                 =1.33*3.14*11*11*11

                                =4.18*11*11*11

                               =4.18*1331

            Volume   =5563.58units^3

The volume of the sphere with radius of 11 units is 5563.58units^3

24 times 4 tons 2 pounds
Iteru [2.4K]
Ayy, so your question is kinda weirdly worded. But I think your asking what is 24 multiplied by 4 tons and 2 pounds.

Well, 2 pounds is equal to 0.00090718 tons.
There is a converter here: https://www.bing.com/search?q=pounds+to+tons&qs=AS&pq=pounds+to+tons&sc=8-14&sp=1&cvid=7BC591B75A8B4......

But now we have 0.00090718 tons as well as 4 tons. Add those together and you get 4.00090718. Now, multiply this by 24. You get: 96.02177232.

Fine the equation, in standard form, of the line passing through the points (3,-4) and (5,1)
Talja [164]

The point-slope form:

y-y_1=m(x-x_1)\\\\m=\dfrac{y_2-y_1}{x_2-x_1}

We have the points (3, -4) and (5, 1). Substitute:

m=\dfrac{1-(-4)}{5-3}=\dfrac{5}{2}\\\\y-(-4)=\dfrac{5}{2}(x-3)

The standard form: Ax+By=C

y+4=\dfrac{5}{2}(x-3)           <em>multiply both sides by 2</em>

2y+8=5(x+3)           <em>use distributive property</em>

2y+8=5x+15            <em>subtract 2y from both sides</em>

8=5x-2y+15          <em>subtract 15 from both sides</em>

-7=5x-2y

<h3>Answer: 5x - 2y = -7</h3>
