Answer:

14.4 units

Step-by-step explanation:

In Trigonometry

$\cos \theta =\frac{Adjacent}{Hypotenuse}\\$

In Triangle DEF,

$\cos F =\dfrac{EF}{DF}\\\cos 26^\circ =\dfrac{EF}{16}\\EF=16 \times \cos 26^\circ\\=14.4$ units (correct to the nearest tenth).$

Suppose the radius of a circle is \color{purple}{3}3start color purple, 3, end color purple. what is its circumference?either en

Vlada [557]

$\text{Consider the circle of radius 3.}\\
\\
\text{we need to find the cirumference of the circle.}\\
\\
\text{we know that the circumference of the circle of radius r is given by}\\
\\
\text{circumference}=2\pi r\\
\\
\text{so using this formula, the circumference of the given circle is}$

$\text{Circumference}=2\pi r\\
\\
=2\pi \times 3\\
\\
=6\pi
\\
\text{so the circumference of the circle is}=6\pi\\
\\
\text{and in decimals, it gives}=6\times 3.14\\
\\
\Rightarrow \text{circumference}=18.84$

Hence the circumference of the circle is: 6π or 18.84 units

The distance between New York and Philadelphia by railroad is 90 miles; the distance between them by river and ocean is 240 mile

VladimirAG [237]

Start with 90/240, then reduce the fraction
you can reduce by dividing each by 10 to get 9/24
reduce more from there, seeing that each number can be divided by 3
9/3 = 3
24/3 = 8
answer 3/8

Victoria filled up her car with gas before embarking on a road trip across the country. The car uses 1.75 gallons of gas for eve

lozanna [386]

Answer:

G = 14 - 1.75(t)

Where G is the number of gallons of gas remaining;

14 represents the amount of gas in gallons in the full gas tank of the vehicle

t is the number of hours

Step-by-step explanation:

Here, we want to write an equation.

We are told that the car uses 1.75 gallons of gas every hour and after 4 hours 7 gallons were left

In the 4 hours, the amount of fuel used will be 1.75 * 4 = 7 gallons

So therefore since we have 7 gallons left, the amount of gallons in the full tank of the vehicle will be 7 + 7 = 14 gallons

Hence, the equation we want to write will be;

G = 14 - 1.75(t)

The populations and areas of four states are shown. A 3-column table has 4 rows. The first column has entries State A, State B,

dedylja [7]

Answer:

Step-by-step explanation:

First, pop. density for State A:

population/area : 1,055,173 / 2,677 = 394.16

For State B:

pop./A : 1,333,089 / 36,418 = 36.61

For State C:

pop.A : 3,596,677 / 5,543 = 648.87

For State D:

pop./A : 6,745,408 / 10,555 = 639.07

Okay!

So with this data, we can easily rule out the first option (State A has the least population, but it isn't the most densely populated). Moving on to the second option, we see that the state with the second-lowest population, State B, also has the lowest population density! Thus, our answer is B (haha which is coincidentally the State name).
