<h2><u><em>BRAINLIEST PLEASE</em></u></h2>

Answer:

27 mph

Step-by-step explanation:

Let the rate of snowmobile be s and the rate at which the pack ice is drifting be z

distance is equal to speed times time

330 = (s + z ) x 12

330 = (s + z ) x 15

solve and get 54 = 2s

that makes s = 27

making your answer 27mph (C)

Find an angle between 0 degrees and 360 degrees that is coterminal with 950 degrees

QveST [7]

Answer:

40 degrees

Step-by-step explanation:

(to find coterminal angles to a given angle, we add 360 degrees to the given angle or subject 360 degrees from the given angle any angle any number of time).

-1400 degrees is negative angl, so to get the coterminal angle between 0 degrees and 360 degrees ( the smallest positive coterminal angle), we must add multiples of 360 degrees until we get a possitive coterminal angle:

-1400 degrees+(360 degrees*4)

=-1400 degrees+1440

=40 degrees

so the answer is 40 degrees

X^3 = 125 over 27 CAN I PLEASE GET HELP

Zinaida [17]

X³ = 125/27

Cube root both sides to isolate the variable:

∛x³ = ∛(125/27)

x = ∛(125/27)

∛125 = 5, ∛27 = 3

x = 5/3

In March, there will be two conferences: one for math and one for history. So far, 7 people have signed up for the math conferen

otez555 [7]

Answer:

After 4 days, the number of people attending both conferences be the same.

Step-by-step explanation:

We are given the following in the question:

Maths conference:

Number of people already signed = 7

Number of people who sign up each day = 2

Thus, the number of people who will sign up for maths conference in x days will be given by the linear function:

$f(x) = 7+2x$

History conference:

Number of people already signed =11

Number of people who sign up each day = 1

Thus, the number of people who will sign up for maths conference in x days will be given by the linear function:

$g(x) =11+x$

Both conference will have same number of people when

$f(x) = g(x)\\\Rightarrow 7 + 2x = 11+x\\\Rightarrow x = 4$

Thus, after 4 days, the number of people attending both conferences be the same.

The length of a rectangular garden is 3 inches greater than twice it’s width find the dimensions if the perimeter is 24 inches

mel-nik [20]

Answer:

width=3

length=9

Step-by-step explanation:

1/2 perimeter: 24/2=12

let x: width; y: lenght

y=2x+3

x=12-y

y=2(12-y)+3

y=24-2y+3

y+2y=27

y=9

x=12-9=3
