1. 2x2 (3+8)
I need the answer

Answers

Answer:

the answer is 44

Step-by-step explanation:

Because (3+8) is in paranthesis, you should do this first: 2x2(11)

Now, because there is no sign between the second 2 and the parantheses, this simply means they are multiplied so now you have: 2x2x11

Now, because they all have the same sign, you can just multiply across:

2x2x11 = 44

A plane leaves the airport in galisteo and flies 170 km at 68 degrees east of north; then it changes direction to fly 230 km at 36 degrees south of east, after which it makes an immediate emergency landing in a pasture. When the airport sends out a rescue crew, in which direction and how far should this crew fly to go directly to this plane?

Answers

Answer:

4.68° south east 317.36 km

Step-by-step explanation:

We can find the angle between the two distances (vectors) because according to the diagram, we can draw two right triangles between them.

The complement of the 36 degree angle is 54 (90-36=54), and the complement of the 68 angle is 22, (90-68=22) the sum of 22 and 54 is 76. So the angle between the two distances is 76.

Then we apply the cosine law

$b^(2) =a^(2) +c^(2) -2*a*c*cosB\n \nb^(2) =230^(2) +170^(2) -2*230*170*cos(76)\n\nb=\sqrt{230^(2) +170^(2) -2*230*170*cos(76)} \n\nb=317.36 km$

then we apply the sin law

$(sin(C))/(c) =(sin(B))/(b) \n\nsin(C)=c*(sin(B))/(b)\n\nsin(C)=170*(sin(76))/(317.36)\n\nsin(C)=0.52\n\narcsin(0.52)=C=31.32\n\n$

and because in any triangle, the sum of the inside angles is equal to 180

$180=76+31.32+68+y\n\ny=180-76-31.32-68\n\ny=4.68^(o)$

180= 76+C+(68+Y)

y=180-76-C-68

So the emergency plane has to travel 317.36 km, 4.68° southeast.

Help!! Is anyone good at algebra??

Answers

Answer:

h = 20 m

Step-by-step explanation:

So you know volume of a cylinder = π*(r^2) * h

and you also know volume of this cylinder = 180π

(volume is also in meters^3)

you can set these volumes equal to one another

180π = π*(r^2) * h

by dividing by π you get this:

180 = (r^2) * h

you need h so you can divide by r^2 to get this

h = 180 / (r^2)

now you just need to plug in the radius you are given which was 3 meters

h = 180 m^3 / (3 m^2)

h = 180 m^ 3 / 9 m^2

h = 20 m

Write an equation for the graph, where y depends on x.

Answers

Answer:

y = -3x + 6

Step-by-step explanation:

Equation of straight line is given by,

y = mx + b

m = slope of the line

b = y-intercept

From the graph attached,

m = $\frac{\text{Rise}}{\text{Run}}$

= $(-6)/(2)$

= -3

y intercept 'b' = 6

Therefore, equation of the line will be,

y = -3x + 6

Question 2Which collection of three side lengths will NOT form a triangle?

6 in, 10 in, 18 in

10 in, 12 in, 15 in

10 in, 15 in, 6 in

10 in, 18 in, 12 in

Answers

Side lengths with 6 in, 10 in, 18 will not form a triangle 'cause we know, that sum of shorter sides must be greater than the longer side but here it's not.

In short, Your Answer would be Option A

Hope this helps!

6 in, 10 in, 18 in
The sides need to be in between (10-6) and (10+6) or between 4 and 16. But the third side here is 18, so that cannot qualify as a side.

Hope this helps.
