Sergio [31]

Answer:

her weekly allowance is $16

Step-by-step explanation:

Let x represent Imani's weekly allowance.

Imani spent half of her weekly allowance playing Mini-golf. This means that the total amount that she spent playing Mini-golf is x/2. The amount that she is left with would be

x - x/2 = x/2

In order to earn more money her parents let her wash the car for $4. This means that the total amount left with her is

x/2 + 4

if she ended with $12, it means that

x/2 + 4 = 12

x/2 = 12 - 4 = 8

x = 2 × 8 = $16

No, if you were to convert 9/4 into a decimal it would be 2.25.

An equilateral triangle has an apothem of 5 cm. Find the perimeter of the triangle to the nearest centimeter.

san4es73 [151]

The apothem is the distance from the center to the midpoint of one of the sides of a regular polygon. You can make a right triangle with the apothem, the line from the midpoint to the corner and the line from the center to the corner. An equilateral triangle has 60 degree angles (180/3). The right triangle has half of one of those angles so 30 degrees. Now we have a 30-60-90 triangle where the short leg is 5cm. The long leg, which is also half of one side of the triangle is thus $5\sqrt{3}$ . A whole side of the triangle is $10\sqrt{3}$ . Multiply that by 3 to get the perimeter of <span> $30\sqrt{3}$ .</span>
