Answer: a. 3.4t (miles)

b. 2.125 miles

c. t = 1.6 hours

Step-by-step explanation:

A) We will use the relation:

Distance = Speed × Time

Distance= 3.4 × t

= 3.4t (miles)

B) If t= 5/8

Distance d= 3.4 × 5/8

= 3.4 × 0.625

= 2.125 miles.

C) If the distance d= 5.44,

Time will be:

d= 3.4t, and we know that d=5.44

Therefore, 5.44 = 3.4t

t = 5.44/3.4

t = 1.6 hours

Johnny's town is having an old-fashioned circus under a large tent. In order to keep the tent from falling down, workers must ti

Zepler [3.9K]

Answer: 62 feet approximately.

Step-by-step explanation:

1. Based on the information given in the problem, you can draw a right triangle as the one shown in the image attached, where the height of the tent is represented with $x$ . Therefore, you can calculate it as following:

$sin\alpha=\frac{oppostite}{hypotenuse}$

Where:

$\alpha=62\°\\opposite=x\\hypotenuse=70$

2. Substitute values and solve for $x$ , then the height of the circus tent is:

$sin(62\°)=\frac{x}{70}\\x=70*sin(62\°)$

$x=61.81$ ≈ $62ft$

How would I start to solve number 15? Would I use distributive property?

natita [175]

$-5-x=2x-(4x+6)$

Using the distributive property is the correct first step. $(4x+6)$ is being multiplied by -1, so distributing gives

$-5-x=2x+(-4x-6)$
$-5-x=2x+((-4x)+(-6))$

Now, using the associative property of addition, you get

$-5-x=(2x+(-4x))+(-6)$
$-5-x=(2x-4x)-6$

Simplify the right hand side:

$-5-x=-2x-6$

Add 5 and $2x$ to both sides.

$(2x+5)-5-x=(2x+5)-2x-6$

On the left side, use the associative property. On the right, commutativity and associativity:

$2x+(5-5)-x=5+(2x-2x)-6$

Simplify.

$2x-x=-1$
$x=-1$

I have 3 countries (Germany, usa, China) with 3 statistics (people per square km, internet users per 100 people, cell phone owne

kolbaska11 [484]

Alright, so if we wanted to take, for example, cell phone owners per 100 people and compare Germany to the USA, we can start by making up a number for Germany - 80 - and a number for the USA - 70. Next, the ratio of people using cell phones is 80/70=8/7 with the numerator being the people from Germany and the denominator being the number from the USA.
