A bag contains only red and blue marbles. Yasmine takes one marble at random from the bag. The probability that she takes a red marble is 1 in 5. Yasmine returns the marble to the bag and adds ﬁve more red marbles to the bag. The probability that she takes one red marble at random is now 1 in 3. How many red marbles were originally in the bag?

In a water treatment plant, water passes through a cone-shaped filter with a height of 4 m and a diameter of 9 m. The water flows from the filter into a cylinder below it. One full cone-shaped filter fills one-fifth of the cylinder.What are the dimensions of the cylinder? Use 3.14 to approximate pi.

A.
h = 3 m; r = 3 m

B.
h = 4.23 m; r = 5 m

C.
h = 15 m; r = 6 m

D.
h = 33.75 m; r = 2 m

so volume of a cone=1/3 times (area of base) times height

area of base=circle so
1/3 times pi times radius^2 times height

height=4
diameter=2radius
diameter/2=radius
9/2=4.5=radius

height=4
radius=4.5
aprox pi at 3.14
1/3 times (3.14 times 4.5^2) times 4=84.78
that's the volume of the cone

volume of cone=1/5 of cylinder

84.78=1/5cylinder
multiply both sdies by 5
423.9=volume of cylinder

volume of cylinder=height times area of base
area of base=3.14 times r^2
v=h3.14r^2
423.9=3.14hr^2
divide both sdies by 3.14
135=hr^2
sincewe are not given the specific ratio of height to radius or such to thecone to the cylinder, we must use trial and error to elimninate wrongchoices

135=hr^2
let's try A

A
135=3(3^3)
135=3(9)
135=27
false
A is wrong

B
4.23=h 5=r
135=4.23 times 5^2
135=4.23 times 25
135=105.75
false
B is wrong

C
h=15 r=6
135=15 times 6^2
135=15 times 36
135=540
false
C is wrong

D
33.75=h 2=r
135=33.75 times 2^2
135=33.75 times 4
135=135

the answer is D since it fitst the dimentions

$(9/2*9/2*4* \pi )/(3)$
= $(81*3.14 )/(3)$
=27*3.14 (the cone's v)
so multiply 5 to the v = 135*3.14 (cylinder's v)
A:3*3*3*3.14=27*3.14 X
B:5*5*4.23*3.14=105.75*3.14 X
C:6*6*15*3.14=540*3.14 X
D:2*2*33.75*3.14=135*3.14 O

If I have 5 potatoes weighing a total of 1 kg what would each potato weigh?

Answers

From the information given, we don't know how much each potato weighs. All we know is that when you add up all 5 of them you get one kilogram.
If all five have exactly the same weight then it's 200 grams.

Each potato would weigh 200 grams. 1 kg is the equivalent to 1000 grams. So, if you divide 1000 by 5, you get 200 grams. Good luck!

What Is The Slope-Intercept Form Of This Equation 3x+9y=18

Answers

Y= -1/3x+2 because The Change in x and the change in y come out to -1/3x then you plug in the coordinates and solve for b. Hope i helped

Answer:

Solve the given equation for y to obtain the slope and y-intercept of this equation: -3x + 9y = 18

Add 3x to both sides: 3x - 3x + 9y = 18 + 3x

Simplifying, 9y = 3x + 18

Dividing both sides by 9 to solve for y:

y = (3/9)x + 2 or (after reduction) y = (1/3)x + 2

The slope is 1/3 and the y-int. is (0,2).

F. 15 times as much as 1 fifth of 12.

Answers

15 × ( ¹/₅ × 12 ) = 36

Further explanation

Order of Operations in Mathematics follow this following rule :

Parentheses

Exponents

Multiplication and Division

Addition and Subtraction

This rule is known as the PEMDAS method.

In working on a mathematical problem, we first calculate operation that is in parentheses, follow by exponentiation, then multiplication or division, and finally addition or subtraction.

Let us tackle the problem!

1 fifth of 12

$(1)/(5) * 12$

15 times as much as 1 fifth of 12

$15 * ((1)/(5) * 12)$

Let's solve the above operations!

$15 * ((1)/(5) * 12) = 15 * ((1 * 12)/(5))$

$15 * ((1)/(5) * 12) = 15 * ((12)/(5))$

$15 * ((1)/(5) * 12) = (15 * 12)/(5)$

$15 * ((1)/(5) * 12) = (180)/(5)$

$15 * ((1)/(5) * 12) = \boxed {36}$

Conclusion:

15 times as much as 1 fifth of 12 → 15 × ( ¹/₅ × 12 ) = 36
