Write the ratio as a fraction in simplest form.<br><br> 10.8 seconds : 36 feet <br><br> (Show work)
vodka [1.7K]

Answer: Ratio as a fraction in simplest form is :

\frac{27}{1}=27

Step-by-step explanation:

Since we have given that

10.8 seconds : 36 feet

As we know that

1\ second=\frac{1}{60}\ mile\\\\1\ second=90\ feet

So, we use it :

10.8 seconds : 36 feet

=10.8\times 90\ feet:36\ feet\\\\=972:36\\\\=27:1

Hence, Ratio as a fraction in simplest form is :

\frac{27}{1}=27

Find the equation of the line with a slope of 12 that passes through the point (3, -1)
Anon25 [30]

Answer:

y = 12x - 37

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

here m = 12, thus

y = 12x + c ← is the partial equation

To find c substitute (3, - 1) into the partial equation

- 1 = 36 + c ⇒ c = - 1 - 36 = - 37

y = 12x - 37 ← is the equation of the line

Aleksandr [31]

<em>The given equation is:  E=17/20 D  , where  E=amount of Euros and D= amount of U.S dollar. </em>

<em> </em>

<em>Now for 1 U.S dollar, we need to plug D=1 into the above equation. So, we will get......... </em>

<em> E=17/20(1)</em>

<em>E=1/20=0.85</em>

<em>0.85 Euros have the same amount as 1 U.S dollar. </em>

Nia solved the equation -1.98 = 5.2v + 13.1. Her answer was v = -2.9. She is fairly confident about her answer, but wants to do
d1i1m1o1n [39]
To solve this, just round each number. -1.98≈-2, 5.2≈5, -2.9≈-3, 13.1≈13. The only answer choice which correctly rounds these is A, -2=5(-3)+13
