Answer:
So K + L + T = 682. So Lou has 62 songs on his device. If Kelly has four times the number of songs that Lou has, then she has 4 x 62 = 248 songs. If Tiffany has six times the number of songs that Lou has, then she has 6 x 62 = 372 songs.

Answer:
28.3 square inches
Step-by-step explanation:
In the question, we are asked to calculate the portion of the area of the cake eaten by Ellie’s sister.
To calculate this, the first thing to do is to calculate the area of the cookie cake. Now, since it’s a round cake, then it must be circular in shape.
Hence we calculate the area.
mathematically the area of a circle can be calculated using the formula;
A = pi * r^2
here our r =6 inches
Substituting this, we have
A = 22/7 * 6 * 6 = approximately 113 sq. inches
we now move on to calculate the portion ate, which is a quarter
That would be 1/4 * 113 = 28.3 sq. inches was eaten
Answer:2
Step-by-step explanation: .5 multiplied by 2. This equals .25, multiply 8 and .25.
Answer:
4,8,9 is not a right triangle
Step-by-step explanation:
<h2><u>A right angled triangle </u></h2>
a right angled triangle makes use of the following equation
c^2 = a^2 + b^2
the values given are 4,8,9
c would be 4
a and b would be e and 9
put these values in the equation
4^2 = 8^2 + 9^2
16 = 145
hence the side lengths<u> 4,8,9 is not a right triangle</u>
Its the last answer because you would move the decimal to the right three places
