Answer:

8.5 hours

Step-by-step explanation:

We know that it takes Nikki 1 hour to walk 4.2 miles.

We need to figure out how long it will take her to walk 35.7 miles.

This is our expression; 35.7 ÷ 4.2.

Let's go ahead and divide these two numbers.

(35.7 ÷ 4.2) = 8.5

So It will take Nikki 8.5 hours to walk 35.7 miles.

From the given tabular data,

Volume of water (V) = 50.0 ml

Mass of water (m) = 49.7 g

So, the density of water (ρ) = Mass / Volume

or, = 49.7 g /50.0 ml = 0.994 g / ml

Actual value of the density of water (ρ') = 0.998 g /ml

So, the percentage error in the density of water

= [( actual value - observed value) / actual value ] ×100

or, = [ (0.998 g /ml - 0.994 g / ml ) / 0.998 g /ml ] ×100

or, = 0.4 %

Hence, the required % error in the density of water will 0.4 %.

Two Step Equations with Fractional Coefficients 23+2/3c=45

Firlakuza [10]

Answer:

c = 33

Step-by-step explanation:

23 + 2/3c = 45

Subtract 23 from oth sides

2/3c = 22

multiply both sides by 3/2

c = 33

Find the value of xxx in the isosceles triangle shown below.

Ivahew [28]

Answer:

$x=10\ units$

Step-by-step explanation:

The picture of the question in the attached figure

we know that

The height of an isosceles triangle divide the triangle into two congruent right triangles.

Applying the Pythagorean Theorem

$(\sqrt{74})^2 =7^2+(\frac{x}{2})^2$

solve for x

$74 =49+\frac{x^2}{4}$

$\frac{x^2}{4}=74-49$

$\frac{x^2}{4}=25$

$x^2=100\\x=10\ units$

For f(x)=2x+1 and g(x)=x^2-7, find (f+g)(x)

labwork [276]

For this case we have the following functions:

$f (x) = 2x + 1\\g (x) = x ^ 2-7$

We must find the following sum of functions:

(f + g) (x)

By definition we have to:

$(f + g) (x) = f (x) + g (x)\\(f + g) (x) = 2x + 1 + x ^ 2-7\\(f + g) (x) = x ^ 2 + 2x-6$

So, we have to:

$(f + g) (x) = x ^ 2 + 2x-6$

Answer:

$(f + g) (x) = x ^ 2 + 2x-6$
