Answer:

3 divided by 1 equals 3

How :

We can write 3 divided by 1 as a ratio, fraction, or equation. Let's try writing this statement in all these ways

3:1

3/1

3÷1

The easiest way for me to solve this question is as a fraction so let's solve it like that. If the denominator is a 1, we immediately know that the answer is the numerator and that you don't need the denominator. so we can take away the 1 from 3/1 and that is how our answer is 3!

Hope this Helps!!! :)

Let me know in the comments if the answer was perfect or if I should change anything!!! :)

What is the length of ST, to the nearest tenth of a yard?
rewona [7]
Let's say that ST is side b
<span><span>Use the Law of Sines to find side b.</span><span> 
   b / sin(B) = a / sin(A)</span><span> 
b / sin(59°) = 7 / sin(79°)</span><span> 
                b = (sin(59°) x 7) / sin(79°)</span><span> 
                b = 6.112

That is answer B.) 6.1 yards

Hope this helps!</span></span>

Can someone please help me solve these two problems and explain them to me? About the one with proportions though... I've always
NeTakaya

Answers:

A) -\frac{11}{4}

C) m_{1}=\frac{Fr^{2}}{G m_{2}}

Step-by-step explanation:

<u>Part 1:</u>

We have the followig equation:

\frac{x-1}{3}-\frac{x+4}{5}=\frac{4x-1}{8}

Calculating the least common multiple (l.c.m) in the denominator in the left side of the equation, being l.c.m=15:

\frac{5(x-1)-3(x+4)}{15}=\frac{4x-1}{8}

Solving for the left part of the equation:

\frac{2x-17}{15}=\frac{4x-1}{8}

Operating with cross product:

8(2x-17)=15(4x-1)

Applying the distributive property:

16x-136=60x-15

Isolating x:

x=-\frac{121}{44}

Dividing numerator and denominator by 11:

x=-\frac{11}{4} Hence, the correct option is A

<u>Part 2:</u>

We have the followig equation:

F=\frac{G m_{1} m_{2}}{r^{2}}

Operating with cross product:

Fr^{2}=G m_{1} m_{2}

Isolating m_{1}:

m_{1}=\frac{Fr^{2}}{G m_{2}} Hence, the correct option is C
