Answer:

12%

Step-by-step explanation:

Interés simple = Principal × Tasa × Tiempo

Tasa = Interés simple / Principal × Tiempo

Principal = 1700 soles

Tiempo = 1 año y 3 meses

12 meses = 1 año

3 meses = 3/12 = 1/4 = 0.25

Tiempo = 1.25 años

Tasa = 255 /1700 × 1.25

= 0.12

= 0.12 × 100

= 12%

Answer:

2√3 = hypotenuse

√3 = side

Step-by-step explanation:

$\sqrt{3^{2} +x^{2} } = 2x \\\sqrt{9 +x^{2} } = 2x\\9+x^{2} =(2x)^{2} \\9+x^{2} = 4x^{2} \\9 = 4x^{2} - x^{2} = 3x^{2} \\3 = x^{2}\\\sqrt{3} = x\\\\2x = 2\sqrt{3}\\$

The double number line shows that 444 bottles of water cost 101010 dollars at a music festival. Based on the ratio shown in the

MrRissso [65]

Answer:

Please see the attachment for double number line.

Explanation:

We are given cost of 4 water bottles is $10

We can write ,

Cost of 4 bottles = $10

Cost of 1 bottle = $2.5

Cost of 2 bottles =$5

Cost of 3 bottles = $3\times 2.5$ = $7.5

Cost of n bottles = $2.5n

Now we draw the double number line.

Bottom line(Line 1) will take as number of bottles:

1 2 3 4 5 6

Above line (Line 2) will show the cost of corresponding number of bottles:

2.5 5 7.5 10 12.5 15

You are facing North. Turn 90 degrees left. Turn 180 degrees right. Turn around to reverse your direction. Turn 45 degrees left.

North
You are facing north. 90 degrees left is west. 180 degrees is now east. Reversing your direction is the same as 180 so your now back to facing west. Turn 45 left you’re now facing south. Reverse again and you’re facing north.

HELP MEEEEEEEEEEEEEEEEEEEE

$A=0.25^2+2*0.25\sqrt{\frac{0.25^2}{4}+ 1.2^2}$ Alright, lets get started.

The side of square base is given 0.25 in. (say a)

The height of pyramid is given 1.2 in. (say h)

The formula for surface area A is given below:

A=a^2+2a √(a^2/4+ h^2 )

Putting the value of a and h .

$A=a^2+2a\sqrt{\frac{a^2}{4}+ h^2}$

Putting the value of a and h

$A=0.25^2+2*0.25\sqrt{\frac{0.25^2}{4}+ 1.2^2} \\A=0.0625+ 0.5\sqrt{\frac{0.0625}{4}+ 1.44} \\A=0.0625+ 0.5\sqrt{0.015625 + 1.44} \\A=0.0625+ 0.5\sqrt{1.455}\\A=0.0625+ 0.5*1.20\\A=0.0625+ 0.60\\A = 0.6625 square inches$

Hence the area of pyramid is 0.6625 square inches. : Hope it will help :)
