Answer:

Neither are correct.

Step-by-step explanation:

The number of legs = the number of ants * 6.

The relationship is L = 6 a   so neither are correct.

Answer: Both equations are incorrect.

Step-by-step explanation:

Ants have 6 legs:

The equation of Elena is:

a = 6*L

where a is ants and L is legs.

this equation says that are equal number of ants tan 6 times the number of legs, this is is not the case;

the number of legs is six times the number of ants, because each ant has 6 legs: L =6*a

the Andre equation is:

L = 0.166*a

Which, again, it is incorrect.

in this case the equation should be:

a = 0.166*L

and the ratio of ants to legs is 1:6 wich means that there is one ant for each 6 legs.

Both options are incorrect

frozen [14]

Answer:

96π

Step-by-step explanation:

You will need the formula for the volume of a cone.

V=\frac{1}{3}πr^{2}h

r= 6 cm

To find the height, you need to use the Pythagorean theorem.

a²+ b² = c² (a and b are the 2 legs and c is the hypotenuse)

b = \sqrt{{c^{2}-a^{2} }

b= \sqrt{10^{2}-6^{2}  } = 8

h= 8 cm

remember PEMDAS!

V=\frac{1}{3}π(6)^{2}8

V=\frac{1}{3}π(36)8

V= π(12)8

V= 96π

Answering in terms of π is more accurate because it is actually infinite so when it gets rounded to 3.14, that is only an approximation of pi. (π is actually 3.1415926535897932384626433 etc.)

Serena has attached a 10 inch ribbon to the corners of a frame to hang it on the wall. The frame 9 inches wide. How far above th
kherson [118]

Answer: The hook would be 2.2 inches (approximately) above the top of the frame

Step-by-step explanation: Please refer to the picture attached for further details.

The top of the picture frame has been given as 9 inches and a 10 inch ribbon has been attached in order to hang it on a wall. The ribbon at the point of being hung up would be divided into 5 inches on either side (as shown in the picture). The line from the tip/hook down to the frame would divide the length of the frame into two equal lengths, that is 4.5 inches on either side of the hook. This would effectively give us two similar right angled triangles with sides 5 inches, 4.5 inches and a third side yet unknown. That third side is the distance from the hook to the top of the frame. The distance is calculated by using the Pythagoras theorem which states as follows;

AC^2 = AB^2 + BC^2

Where AC is the hypotenuse (longest side) and AB and BC are the other two sides

5^2 = 4.5^2 + BC^2

25 = 20.25 + BC^2

Subtract 20.25 from both sides of the equation

4.75 = BC^2

Add the square root sign to both sides of the equation

2.1794 = BC

Rounded up to the nearest tenth, the distance from the hook to the top of the frame will be 2.2 inches
