tail: 4.5x5/2=11.25, 4.5x3/2=6.75, 11.25+6.75=18

top fin: 3x2.25/2=3.375, 3x0.75/2=1.125, 3.375+1.125=4.5

bottom fin: 1x1/2= 0.5, 1x0.5/2=0.25, 0.5+0.25=0.75

nose: 4.5x2=9

between tail and body: 2.5x2=5

corners on body: 1.5x0.5/2x4=1.5

top and bottom on body: 0.5x5x2=5

body: 1.5x2+5=8, 2x2=4, 4x8=32

total: 18+4.5+0.75+9+5+1.5+5+32=75.75

____ [38]

When adding two rational numbers,if a pair of addends has opposite signs ,then the sum will have the sign of the addenda with the greater value among the two.

These examples can better illustrate this concept:
Example 1:
23 + (-3) = 20 (The greater among the two is positive and the result is also positive)

Example 2:
-23 + 3 = -20 (The greater among the two is negative and the result is also negative)

Find the sum. Express your answer in simplest form. 4x+6/y^2-9 + 8x-7/y^2-9

Amanda [17]

It looks like you already have a common denominator (y^2-9). So, you can just add the two numerators and put that over the common denominator. Hope this helps!

Thereare 30 students in mr.holland's music class.if 30% of the students play in the school band,how many students in the class p

stiv31 [10]

9 students in the class play in the school band.

30% of 30
Well, when doing a percentage you first turn the percentage into a decimal (move the % two units to the left). So 30% = 0.3

In math, the word of means multiplication, so: 0.3 x 30
Which equal 9.

You can also turn the percentage into a fraction, it's really up to preference.

30/100 of 30 = 3/10 of 30 = 3/10 x 30 = 3/10 x 30/1 = 9/1 or 9
