Answer:

13

Step-by-step explanation:

78 + b = 91            Equation: Subtract 78 from both sides.

b = 91 - 78            

b = 13

You don't need her position in the game or the fact that 91 placed her second.  

=====================================================

Explanation:

Refer to the diagram below. I've drawn diagonal that slopes upward. This diagonal cuts the quadrilateral into two triangles: One is equilateral and the other is isosceles.

The equilateral triangle marked in blue has all three angles 60 degrees each.

Note that the 60 and y angles combined to form 130, so,

60+y = 130

y = 130-60

y = 70

Then focus on the isosceles triangle (angles y, w and w). These three interior angles must add to 180

y+w+w = 180

70+2w = 180

2w = 180-70

2w = 110

w = 110/2

w = 55

This adds onto its adjacent neighbor of 60 to get w+60 = 55+60 = 115 degrees which is the value of x.

Answer:

1440 in^3

Step-by-step explanation:

The formula for finding volume is l*h*w.

l*h*w is length multiplied my height multiplied my width. Lets use this formula to find the volume of the rectangular prism.

Here is the information we know about the rectangular prism:

the length is 20 inches

the height is 6 inches

the width is 12 inches

Lets put this information into the formula to find the volume of the rectangular prism. I will show the work in steps so it is easy to follow.

Step one: plug the given information into the formula.

l*h*w = 20*6*12

Step two: Solve the equation.

20*6*12 = 120*12 = 1440

And there you have it! Our final answer is 1440 in^3.

Answer:

Step-by-step explanation:

(a + b)² = a² + 2ab + b²

a = 2x   ;  b = 3y

(2x)²= 2x * 2x = 4x²

(3y)²  =3y * 3y = 9y²

(2x + 3y)² = (2x)² + 2 *2x*3y + (3y)²

              = 4x² + 12xy + 9y²

Answer:

43°

Step-by-step explanation:

to calculate this angle you have to find the value of angle x because the two are equal since they originate from the same arc to find angle y,you subtract the sum of 90 and 47 by 180, because they form a triangle and the top part of that triangle is 90°( the angle at the circumference is half the angle at the center 180/2=90°)

90+47+x=180

x=180-137

x=43°

therefore y=43

Answer:

Step-by-step explanation:

The body of the Cylinder.

Formula

Area of the body = circumference * length

circumference = 2*pi * r

r = 6 m

Circumference = 2 * 3.14 * 6

Circumference = 12 * pi

Area of body = 12*pi * length

area of body = 12*9 * pi

Area of body = 108* pi

Two ends

The diagram is not complete enough to know whether or not there are 2 ends or one. I'll assume 2.

Area = 2 * pi r^2     For both

Area = 2 * pi * 6^2

Area = 72 pi

Total Area

Total area = 72 pi +108 pi

Total area = 180 pi

Total Area = 180 * 3.14

Total Area = 565.2

(w + 4)(w^2 + 3w - 6)

w^3 + 3w^2 - 6w + 4w^2 + 12w - 24

w^3 + 7w^2 + 6w - 24

We are required to find the volume of the object which comprises of a cylinder and a cone

The volume of the object is 108 in³

Volume of a cylinder = πr²h

π = 3

r = diameter / 2 = 4 in / 2 = 2 in

h = 8 in

Volume of a cylinder = πr²h

= 3 × (2 in)² × 8 in

= 3 × 4 in² × 8 in

= 96 in³

Volume of a cone = πr²h/3

= (3 × (2 in)² × 3 in) / 3

= (3 × 4 in² × 3 in) / 3

= 36 in³ / 3

= 12 in³

The volume of the object can be found by adding the volume of the cylinder and the volume of the cone

Total volume = Volume of a cylinder + Volume of a cone

= 96 in³ + 12 in³

= 108 in³

Answer:

27 inches

Step-by-step explanation:

We can use The Pythagorean theorem

a^2+b^2 = c^2  where a and b are the legs and c is the hypotenuse

21.6 ^2 + 16.2^2 = c^2

466.56+262.44 = c^2

729 = c^2

Taking the square root of each side

sqrt(729) = sqrt(c^2)

27  = c

1. (-(2^(-3)))*(-(3^(-2.)))=0.01388888888

2. -294912

3. 16

Answer:

It's False Because Hypotenuse will be the longest side of leg here

For the equation (2k + 1)x² + 2x = 10x - 6 to have two real and equal roots, the value of k = 5/6.

Since the equation is (2k + 1)x² + 2x = 10x - 6, we collect subtract 10x from both sides and add 6 to both sides.

So, we have (2k + 1)x² + 2x - 10x + 6 = 10x - 6 - 10x + 6

(2k + 1)x² - 8x + 6 = 0

For the equation, (2k + 1)x² + 2x = 10x - 6 to have two real and equal roots, this new equation (2k + 1)x² - 8x + 6 = 0 must also have two real and equal roots.

For the equation to have two real and equal roots, its discriminant, D = 0.

D = b² - 4ac where b = -8, a = 2k + 1 and c = 6.

So, D =  b² - 4ac

D =  (-8)² - 4 × (2k + 1) × 6 = 0

64 - 24(2k + 1) = 0

Dividing through by 8, we have

8 - 3(2k + 1) = 0

Expanding the bracket, we have

8 - 6k - 3 = 0

Collecting like terms, we have

-6k + 5 = 0

Subtracting 5 from both sides, we have

-6k = -5

Dividing through by -6, we have

k = -5/-6

k = 5/6

So, for the equation (2k + 1)x² + 2x = 10x - 6 to have two real and equal roots, the value of k = 5/6.
