53 + 44 + X = 180
X = 83

We know, sum of all angles in a triangle is equal to 180
So, x + 44 + 53 = 180
x + 97 = 180
x = 180 - 97
x = 83

In short, Your Answer would be 83

Hope this helps!

Can someone answer B please???
lbvjy [14]
A)

150 were surveyed, possible outcomes, and 132 said they prefer dogs, favorable outcomes,   132/150 or 22/25 or 0.88, now 0.88 * 100 is just 88, namely 88% is the probability.

b)

since we know is 88%, what is 88% of 100?  (88/100) * 100, 0.88 * 100, or just 88 students.

c)

18/150 or 3/25 or 0.12 namely 12%,

what's 12% of 300?  (12/100) * 300, or 0.12 * 300, so just 36 students.

From a thin piece of cardboard 30 in. by 30 in., square corners are cut out so that the sides can be folded up to make a box. Wh
Brilliant_brown [7]

Answer:

Dimensions 5in x 10in x 10in will yeild a box with a max. volume of  500 cubic inches

Step-by-step explanation:

Volume =  height x length x width

considering 'x' as the length of the square corners that has been cut out from the cardboard and also, that is height of the cardboard box.

square corners are cut out so that the sides can be folded up to make a box, cardboard sides would reduce by 2x

therefore,

V = x  (30-2x) (30-2x) ---> eq(1)

V=( 30x - 2x²) (30-2x)

V= 900x- 60x² - 60x² + 4x³

V=  4x³ - 120 x²+ 900x

Taking derivative w.r.t 'x'

dV/dx = 12x² - 240 x +900

dV/dx = 4 (3x² - 60x +225)

For maximum dV/dx, make it equal zero

dV/dx = 0

so,  4 (3x² - 60x +225)=0

3x² - 60x+225=0   (taking 3 common)

x² - 20x + 75 =0

Solving this quadratic equation

x² - 15x -5x + 75 =0

x(x-15) - 5(x-15) =0

Either (x-15)=0

x=15

Or x-5=0

x = 5

if we substitute x=15 in eq(1), volume becomes zero.

therefore, x cannot be 15

When x= 5

eq(1)=>V = 5  (30-2(5)) (30-2(5))

V= 5 (10) (10)

V= 500 cubic inches,

Therefore, Dimensions 5in x 10in x 10in will yeild a box with a max. volume of  500 cubic inches
