Answer:

choice b)

h = 13

g = 18.38 or 13sqrt 2

Step-by-step explanation:

tan 45 = h/13

1 = h/13

h = 13

cos 45 = 13/g

0.7071 = 13/g

g = 18.38

Solve.<br> 4(y + 4) = 32
MakcuM [25]

Answer:

y = 4

Step-by-step explanation:

4*y = 4y

4*4 = 16

4y+16=32

to get 4y alone, we subtract 16 from 32.

32-16 = 16

4y = 16

to get y alone, we divide 4 by 16

16/ 4 = 4

so, y = 4

You fly a helicopter for 20 minutes that goes at a speed of 240 km per hour.how far did you go
alina1380 [7]
80 km
You do 240/60 which is 4 and then times that by 20. By dividing 240 by 60 you are finding how far it goes per minute and then you times that by how many minutes(20) which is 80 km

Help please help me its a hard one
DanielleElmas [232]

Answer:

The sum of a and b is 12.

Step-by-step explanation:

Try drawing this figure. ABCD would actually be a triangle, rather than the common quadrilateral you would expect -  considering there are 4 points plotted. Therefore, we would have to find the distance between respective points ( 0, 1 ) and ( 2, 5 ) / ( 2, 5 ) and ( 7, 0 ) / ( 0, 1 ) and ( 7, 0 ). Let's apply the distance formula and calculate the distance between each point, therefore determining the perimeter.

Distance between points ( 0, 1 ) and ( 2, 5 )

= \sqrt{(2-0)^2+(5-1)^2}

= \sqrt{(2)^2+(4)^2}

= \sqrt{4+16}

= \sqrt{20} = 2\sqrt{5}

Distance between points ( 2, 5 ) and ( 7, 0 )

= \sqrt{(7-2)^2+(0-5)^2}

= \sqrt{5^2+(-5)^2}

= \sqrt{25+25}

= \sqrt{50} = 5\sqrt{2}

And you can calculate the distance between points ( 0, 1 ) and ( 7, 0 ) to be exactly 5\sqrt{2} as well. Therefore, you can say that the perimeter of this triangle is 2(5\sqrt{2}) + 2\sqrt{5} = 10\sqrt{2} + 2\sqrt{5}. Note that this is similar to the form we are given. Thus, a = 10, and b = 2 - making it's sum 10 + 2 = 12.
