A snail travels at a rate of 2.58 feet per minute. How gas will he travel in 9 minutes?

alukav5142 [94]

A snail travels at a rate of 2.58 feet PER MINUTE. After 9 minutes, it will travel 2.58 * 9 feet.

2.58 * 9 = 23.22 feet.

The snail travels 23.22 feet in 9 minutes.

You can see that it travels 2.58 feet per minute. In the next minute, it will travel another 2.58 feet. And so on until the 9th minute passes. This is the same as:

2.58 + 2.58 + 2.58 + 2.58 + 2.58 + 2.58 + 2.58 + 2.58 + <span>2.58 = 9 * 2.58 = 23.22</span>

A Square has the vertices at (-2,6) (6,1) (1,-7) (-7,-2). At what point do the diagonals of the square intercect

DerKrebs [107]

Answer: At point ( $-\frac{1}{2},-\frac{1}{2}$ )

Step-by-step explanation: <u>Diagonal</u> is a line uniting two opposite points. In a square, the diagonals intersect in a 90° and bisect each other, i.e., divides each diagonal into two segments of the same length.

In other words, the diagonals of a square meet at their midpoint, which is found as the following:

(x,y) = $(\frac{x_{1}+x_{2}}{2} ,\frac{y_{1}+y_{2}}{2})$

The opposite vertices of the given square are (-2,6) and (1,-7).

So, the intersection is

(x,y) = $(\frac{-2+1}{2} ,\frac{6-7}{2})$

(x,y) = $(-\frac{1}{2},-\frac{1}{2} )$

The diagonals of square with vertices (-2,6)(6,1)(1,-7)(-7,-2) intersect at point $(-\frac{1}{2},-\frac{1}{2} )$ .

Hailey is scuba diving in the ocean. Her boat is anchored 300 feet away at a 30° angle of depression. If her diving partner is 2

victus00 [196]

Answer:

B)313 ft

Step-by-step explanation:

Hello,I think I can help you with this

to solve this you need to find all the measures of the rigth triangle formed by Hailey, the boat, and the point on the surface of the sea just above the head of Hailey

Step 1

define

triangle

Hypotenuse=300 feet

opposite side=y

adjacent side=x

angle of depression =30°

Step 2

find the distances

$cos\alpha =\frac{adjancent\ side}{hypotenuse}\\\\hypotenuse*cos\alpha =adjancent\ side\\ so\\x=adjancent\ side=hypotenuse*cos\alpha\\\\x=300\ft*cos 30 \\\\x=259.8076$

so, the point on the surface of the sea just above hailey is 259.8076 ft from the boat

$sin\alpha =\frac{opposite\ side}{hypotenuse}\\\\hypotenuse*sin\alpha \\y=opposite\ side\\ so\\y=opposite\ side=hypotenuse*sin\alpha\\\\y=300\ft*sin 30 \\\\y=150$

hailey is at a depth of 150 feet

Step 3

now,her partner is 25 feet directly below her,it is

partner's depth is =hailey is at a depth of 150 feet+25

Y=175

he is at the same distance from de boat ( horizontal),because it is the same point in the sea surface.

X=259.80

Step 4

to find the distance between the partner and the boat we can use

Pythagoras theorem

$adjacentside^{2} +opposite side^{2} =hypotenuse^{2} \\\sqrt[2]{adjacentside^{2} +opposite side^{2}} =Hypotenuse\\Hypotenuse=\sqrt[2]{175^{2} +259.8076^{2}} \\\\Hypotenuse=313.24 ft$

so, Hailey's diving partner is 313 ft away from the boat(B)

Have a great day.

How many ways can 5 books be arranged on a shelf

Zielflug [23.3K]

There are very many ways to this!
We can have horizontal, vertical, some can be laying down wile others are standing up, some could be standing up and the others layed down on top of them etc.
but in this case it would be 120 ways.
