Answer:

Wanda and Dave will catch each other in 54 seconds after Dave starts walking.

Step-by-step explanation:

Let Wanda and Dave catch each other when x be the time after Dave starts walking and y be the distance covered by them

It is given that Wanda started walking along a path 27 seconds before Dave and the constant speed of Wanda is 3 feet per second.

speed=\frac{distance}{time}

3=\frac{y}{x+27}

y=3(x+27)

 y=3x+81                          .... (1)

The constant speed of Dave is 4.5 feet per second.

4.5=\frac{y}{x}

y=4.5x                                .... (2)

Equate equation (1) and (2).

3x+81=4.5x

81=1.5x

Divide both sides by 1.5.

\frac{81}{1.5}=x

54=x

Therefore, Wanda and Dave will catch each other in 54 seconds after Dave starts walking.

Someone explain!! geometry
ikadub [295]

Step-by-step explanation:

sin 0 = opposite ÷ hypothenus

sin 0 = 3 / 5

3 / 5 = x / 15

5 × n = 15

n = 3

x = 3 × 3 = 9

y = use pythagoras

= 12

tan 0 = opposite ÷ adjacent

tan 0 = 9/12

Which is the correct way to evaluate the expression 48 - (29-17)
Nadusha1986 [10]

Answer:

The correct way to evaluate this expression is my following the order of operations PEMDAS

P=Paranthesis

E=Exponents

M/D=multiply/divide

A/S=add/subtract

The first step in 48-(29-17) is to do what's inside the paranthesis

48-12 (29-17=12)

Then you would subtract 48-12

48-12=36

Your final answer is

36

Hope this helps ;)
