2 miles per hour
all you have to do is multiply 1/3 by 6 since she only walks 1/3 miles in 1/6 of an hour and you want to find the miles walked in a hour<span />

6.2 yd
krok68 [10]

Answer:

60.26yd³

Step-by-step explanation:

Since we are not given the diagram, let us assume that;

Length of the base = 5.4yd

Height of the pyramid = 6.2yd

volume of the square pyramid = BH/3

B is the base area = L^2

B = 5.4²

B = 29.16yd²

H = 6.2yd

Get the volume

volume of the square pyramid = 29.16*6.2/3

volume of the square pyramid = 180.792/3

volume of the square pyramid = 60.26yd³

Hence the volume of the square pyramid to nearest hundredth is 60.26yd³

Please help<br><br> Boats A, B, C, and D are all the same distance from Boat O.
BlackZzzverrR [31]

Answer:

α = 62°

β = 56°

gamma = 90°

Step-by-step explanation:

ΔAOB is isosceles, so m∠A = m∠ABO = 28

28 + 28 + m∠AOB = 180

m∠AOB = 180 - 28 - 28 = 124

β = 180 - 124 = 56

arcAB = 124

ΔBOC is isosceles.  α = m∠BCO = 1/2(arc AB) = 1/2(124) = 62

∠D is inscribed in a semicircle

m∠D = gamma = 90°

1. If the same number is added to the numerator and subtracted from the denominator of 23/12, the resulting fraction is equivale
ICE Princess25 [194]

Answer:

The number is -2

Step-by-step explanation:

step 1

Find the reciprocal of 2/3

Remember that when multiply a number by its reciprocal, the result is 1

so

The reciprocal of 2/3 is 3/2

step 2

Let

x-----> the number added to the numerator and denominator

\frac{23+x}{12-x}=\frac{3}{2}

Solve for x

2(23+x)=3(12-x)\\46+2x=36-3x\\2x+3x=36-46\\5x=-10\\x=-2

step 3

verify

\frac{23+x}{12-x}

substitute x=-2

\frac{23-2}{12+2}

\frac{21}{14}

Simplify

\frac{3}{2} ----> is ok

therefore

The number is -2

Which equation results from adding the equations in this system?
eimsori [14]

Answer: 3x=3

Step-by-step explanation: Let's divide this into parts--

1. Adding the x variables: -2x+5x or 5x-2x = 3x.

2. Adding the y variables: y-y or -y+y = 0. (The negative and the positive y cancel each other out.)

3. Adding the numbers: 8-5 or -5+8 = 3.

Now just put it back into an equation: 3x + 0 = 3.

We don't need to add the 0, so the equation changes into 3x = 3.
