Pythagoras theorem

diagonal² = length² + width²

13² = 12² + width²

169 = 144 + width²

25 = width²

width = 5m

so, Oakdale Avenue is 5m wide.

Step-by-step explanation:

I assume they intersect at a right angle (90°).

then the intersection is a rectangle with one side being 12 m, and the diagonal being 13 m long.

the diagonal is the Hypotenuse (baseline) of a right-angled triangle with the length and the width of the rectangle as legs.

so, by using Pythagoras we have

diagonal² = length² + width²

13² = 12² + width²

169 = 144 + width²

25 = width²

width = 5 m

so, Oakdale Avenue is 5 m wide.

A scientist is cooling a liquid at a steady rate. The temperature of the liquid changed by −82 1/2 °C over 2 1/5 minutes. What w
dangina [55]

Answer: 37.5^{\circ}  or  37\dfrac{1}{2}^{\circ}

Step-by-step explanation:

Given : The temperature of the liquid changed by -82\dfrac{1}{2}^{\circ}C over 2\dfrac{1}{5} minutes.

We can write [tex]82\dfrac{1}{2}=\dfrac{82\times2+1}{2}=\dfrac{165}{2}

2\dfrac{1}{5}=\dfrac{11}{5}

Now, the statement becomes ,

The temperature of the liquid changed by -\dfrac{165}{2}^{\circ}C over \dfrac{11}{5} minutes.

i.e. temperature changed in \dfrac{11}{5} minutes =  -\dfrac{165}{2}^{\circ}C

Now, by Unitary method,

The temperature changed in 1 minute =   \dfrac{165}{2}\times\dfrac{5}{11}^{\circ}C

⇒ The temperature changed in 1 minute = 37.5^{\circ} or  37\dfrac{1}{2}^{\circ}

A woman bought 100 Christmas cards. For the ones that sing a song when you open them, she paid 30 cents each. For the rest she p
lapo4ka [179]
.05c+.3s=10.25, c+s=100, c=100-s  (c is for cards that don't sing and s is for those that do :P)

.05c+.3s=10.25 and c=100-s makes the equation become:

.05(100-s)+.3s=10.25

5-.05s+.3s=10.25

.25s=5.25

s=21, and since c=100-s

c=79

So she bought 21 of the more expensive singing cards...
