Answer:

777.9 meters

Step-by-step explanation:

From the given figure the angle adjacent to 40 degree is 50 degree

because it forms a right angle triangle (90 degree)

Now we use trigonometric ratio to find out the hypotenuse x

cos = adjacent side / hypotenuse

cos(50)= \frac{adjacent}{hypotenuse}

cos(50)= \frac{500}{x}

Cross multiply it

x= \frac{500}{cos(500)}

x=777.8619

So x= 777.9 meters

Answer:

777.9 meters

Step-by-step explanation:

Notice that the angles of the right triangle are 40 and 50 degrees, with the 500 meter side adjacent to the 50 degree angle. Now, we can set up an equation: cos (50 degrees) = 500 / x. Use a calculator to find that the answer is 777.9.

Five pounds of birdseed is used to fill 4 identical bird feeders.
enyata [817]

Answer:

a. We need 1/4 for each feeder  

b. To fill each feeder we need 1.25 pounds

c.  We need 60 ounces to fill three bird feeders

Step-by-step explanation:

Five pounds of birdseed is used to fill 4 identical bird feeders,  

a. We divide all the birdseed in 4 feeders, so,  we need 1/4 for each feeder.

b. If we use 5 pounds for the 4 feeders,  so each feeders will take 1/4 of the 5 pounds

=1/4 x 5=1.25 pounds

c. To fill three bird feeders we have to multiply the amount of pounds by feeder by 3 feeders

=1.25 pounds x 3

= 3,75 pounds

If 16 ounces are a pound

so,  16 x 3.75 = 60 ounces

a cone has a volume of 6 cubic inches. what is the volume of a cylinder that the cone fits exactly inside of
ella [17]

Answer:

= 18 cubic inches

Step-by-step explanation:

The volume of a cone is given by the formula;

V = 1/3 × base area × height

While that of cylinder is given by the formula;

Volume = Base area × height

Since we need the cylinder to fit exactly inside the cone, then it  means that their bases are the same and heights are the same.

Therefore;

The cone has three times less volume compared to the cylinder.

Thus;

Volume of the cylinder = Volume of cone × 3

                                       = 6 In³ × 3

                                       <u>= 18 cubic inches</u>

Find the area and perimeter.
DanielleElmas [232]

Step-by-step explanation:

Perimeter = 12 + x + 6 + 2x + 5

Perimeter = 3x + 23.

Area = ½ × b × h

Area = ½ × 12 × (x + 6)

Area = 6(x + 6)

Area = 6x + 36
