Angle of elevation is the angle from the banana up to the plane, which is 23 degrees.

The distance from the banana to the plane is the angle line labeled x.

The distance from the plane to the ground is the vertical line labeled 2500m.

Nothing important would be j.

The perimeter of a building is 900 feet. If the length of the building is 400 feet, find the width. How many lights will be need

Helen [10]

Answer:

The width of the building is 50 lamps and 60 lamps will be needed.

Step-by-step explanation:

The perimeter is computed by the sum of the sides of the building, since the length and width are equal on the oposite sides of the building, the perimeter is given by:

perimeter = 2*length + 2*width

900 = 2*(400) + 2*width

2*width + 800 = 900

2*width = 900 - 800

2*width = 100

width = 100/2 = 50 feets

To know how many lights bulbs will be needed we need to take the perimeter of the building and divide it by the space between the lamps. We have:

number o lamps = 900/15 = 60 lamps

If x^2 = 30, what is the value of x?

Lapatulllka [165]

$x= +\sqrt{30} ~or ~ -\sqrt{30}$
I'm not sure why ± that sybol isn't working
all together you can write $x=±\sqrt{30}$

Ughh just ignore the "A" symbol .-.

Sharonda is plotting quadrilateral PQRS on the graph below. She will plot the fourth and

lana [24]

Answer:

11 units

Step-by-step explanation:

Length of side PS can be calculated using the distance formula, $d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

Where,

$P(-2, 5) = (x_1, y_1)$ (the coordinate of P is gotten from the graph)

$S(9, 5) = (x_2, y_2)$ (given)

$PS = \sqrt{(9 - (-2))^2 + (5 - 5)^2}$

$PS = \sqrt{(11)^2 + (0)^2}$

$PS = \sqrt{121} = 11 units$

PLS HELP ME ASAP WITH 1, 2, 5, 6, 11, and 12 PLS!!

melamori03 [73]

1-

number 2) is correct

2- 3) is true

11) Jacob is not correct. because 6radical 5 is irrational

12) radical 20 is an irrational number but

so a+b is irrational

but
$\sqrt{225} = 15 \\ it \: is \: rational$

so b+c is rational

good luck
