Answer: I replaced pi with 3.14 in my calculator just so you know.

Cylinder: 251.2, Cone 1: 83.7, Cone 2: 251.2, Sphere: 62.8, 25 times

Step-by-step explanation:

<em>Cylinder:</em>

Cylinder equation: volume = π · r2 · h

High 8, radius is 5-

π · 5 · 2 · 8 = 251.2

<em>Cone 1:</em>

Cone equation: volume = (1/3) · π · r2 · h

High 8, radius is 5

(1/3) · π · 5 · 2 · 8 = 83.7

<em>Cone 2:</em>

Cone equation: volume = (1/3) · π · r2 · h

High 24, radius is 5

(1/3) · π · 5 · 2 · 24 = 251.2

<em>Sphere:</em>

Sphere equation: volume = (4/3) · π · r3

Radius is 5

(4/3) · π · 5 · 3 = 62.8

<em>Amount times:</em>

62.8/83.7 = 0.75....

0.75 = 75%

100-75 = 25

I think it is 25, not 100% sure.

By the way im not 100% sure with my answers! But if this is right and you found this helpful that is all that counts!

Given that the value of b can never be equal to -1, determine if the equations are intersecting, parallel, or coincident.
eimsori [14]
<h3>Answer: A) intersecting</h3>

-----------------------------------------------

Work Shown:

Solve the first equation for y

x+y = ab

y = -x+ab

y = -1x + ab

slope = -1, y intercept = ab

-----------

Solve for y in the second equation

bx - y = a

bx - y - a = 0

bx-a = y

y = bx - a

Slope = b, y intercept = -a

-----------

The first equation has a slope of -1. The second equation has a slope of b.

Since b cannot equal -1, this means the two equations have different slopes. It is impossible for these two lines to be parallel, because parallel lines have equal slopes. The different slope values tell us the lines cross at exactly one point.

a group of students decided to collect as many paise (1/100 RS.) from each member of the group as is the number of members. If t
Softa [21]

Answer:

Let the no. Of members be x

Rs. 59.29 = 5929 paise

5929/x = x

x^2 = 5929

Therefore x = 77

No. Of members = 77

Hope this helps!

Write the quadratic equation whose roots are 6 and 3, and whose leading coefficient is 4
nekit [7.7K]

If α and β are the Roots of a Quadratic Equation ax² + bx + c then :

✿  Sum of the Roots : α + β \mathsf{= \frac{-b}{a}}

✿  Product of the Roots : αβ \mathsf{= \frac{c}{a}}

Let the Quadratic Equation we need to find be : ax² + bx + c = 0

Given : The Roots of a Quadratic Equation are 6 and 3

⇒ α = 6 and β = 3

Given : The Leading Coefficient of the Quadratic Equation is 4

Leading Coefficient is the Coefficient written beside the Variable with Highest Degree. In a Quadratic Equation, Highest Degree is 2

Leading Coefficient of our Quadratic Equation is (a)

⇒ a = 4

⇒ Sum of the Roots \mathsf{: (6 + 3) = \frac{-b}{4}}

⇒ -b = 9(4)

⇒ b = -36

⇒ Product of the Roots \mathsf{: (6 \times 3) = \frac{c}{4}}

⇒ c = 18 × 4

⇒ c = 72

⇒ The Quadratic Equation is 4x² - 36x + 72 = 0
