Find the area of Khianna's fish. I WILL GIVE YOU 90 POINTS. IF IT'S AN IRRELEVANT ANSWER JUST FOR POINTS IT WILL BE DELETED.

Soloha48 [4]

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

total area of khianna's fish is 75.75 cm.

hope this helps

The table below represents a linear function f(x) and the equation represents a function g(x):

Goshia [24]

The slope of f is 10 because as x increases by 1, f(x) increases by 10.The slope of g is lesser at 5, because every time x increases it only increases by 5. By plugging in 1 and 2 to g(x), we can see that g(2)=11, which is 5 more than g(1)=6.

A right rectangular prism has edges of 8 feet, 4 feet, and 1/2 foot. How many cubes with side lengths of 1/2 foot would be neede

Ksenya-84 [330]

Answer:

Step-by-step explanation:

From the question we are told that

Edges of 8 feet, 4 feet, and 1/2 foot

Generally the volume V_p of the right rectangular prism is mathematically represented as

$V_p=8*4*0.5$

$V_p=16$

Generally volume of the cube V_c is mathematically given as

$V_c =(\frac{1}{2})^3$

$V_c =\frac{1}{6}$

Therefore total number of cubes is given as

$V=\frac{V_p}{V_c}$

$V=\frac{16}{\frac{1}{6}}$

$V=96$
