A measuring cylinder of radius 3cm contains water to a height of 49cm. if this water is poured into a similar cylinder of radius 7cm, what will be the height of the water column​

Answers

Answer 1

Hey there! I'm happy to help!

Hey there! I'm happy to help!

First, let's find the area of the circle of the first cylinder. To do this, we square the radius and multiply by 3.14.

3²=9

9×3.14=28.26

Now we multiply by our height of 49 cm to see how much water there is.

28.26×49=1384.74

Now, let's find the area of the circle of the 7 cm cylinder.

7²=49

49×3.14=153.86

Now, we will take our liquid amount (volume) and divide by this circle amount (base) to find the number of centimeters of height of the water column.

1384.74÷153.86=9

So, the height of our water column will be 9 cm.

Have a wonderful day and keep on learning! :D

What is the probability of a red on this spinner?
Be sure to reduce.

Answers

Answer:

2/8 or 1/4 simplified

Step-by-step explanation:

If you count how many equal sections there are, you will see there are 8, and 2 or those 8 sections are red so that would easily give you your answer, 2/8.

And to simplify it divide both the top and the bottom by 2 and that gives you 1/4.

Hope the helps! :)

The probability of a red on this spinner would be 1/4.

Used the concept of probability that states,

The term probability refers to the likelihood of an event occurring. Probability means possibility.

Given that,

A spinner is shown in the image.

Since there are a total of 8 parts with different colors.

And, the number of red colors on this spinner is 2.

Hence, the probability of a red on this spinner would be,

P = 2 / 8

P = 1 / 4

Therefore, the probability is 1/4.

Step-by-step explanation:

as a fraction it is per definition a rational number.

and the real numbers are a superset of radical numbers.

but 3/2 is not a natural, integer or whole number, as they can all be written as numbers without digits after the decimal point.

and it is a a rational number not irrational, as that would be all numbers with digits after the decimal point, that cannot be expressed as fractions.

Ellie wants to double her savings
of $5000 by investing her money
for 20 years.
What interest rate does
she need to look for?
Give your answer to 1 d.p.

Answers

Answer: Interest rate she needs to look for is 5%

Step-by-step explanation:

P = 5000

A = 5000*2 = 10,000

T = 20 yrs

R = ?

now

I = A-P

I = 10,000-5000

I = 5000

Now

R = 100*I/P*T

R = 100*5000/5000*20

so, R = 5%

How many number less than 300 is exactly divisible by 8, 12, 18?​

Answers

Count how many multiples of 8, 12, or 18 there are in the range {1, 2, 3, …, 300}:

⌊300/8⌋ = 37

⌊300/12⌋ = 25

⌊300/18⌋ = 16

(where ⌊n⌋ denotes the floor of n, i.e. the largest integer that is smaller than n; for instance, 300/8 = 37.5, so ⌊300/8⌋ = ⌊37.5⌋ = 37)

Take pairwise LCMs, as well as the LCM of all three numbers:

LCM(8, 12) = LCM(2³, 2²×3) = 2³×3 = 24

LCM(8, 18) = LCM(2³, 2×3²) = 2³×3² = 72

LCM(12, 18) = LCM(2²×3, 2×3²) = 2²×3² = 36

LCM(8, 12, 18) = LCM(2³, 2²×3, 2×3²) = 2³×3² = 72

Count how many multiples there are of each of these LCMs that are less than 300:

⌊300/24⌋ = 12

⌊300/72⌋ = 4

⌊300/36⌋ = 8

Then, using the inclusion/exclusion principle, the number of numbers less than 300 that are exactly divisible by 8, 12, or 18 is

{multiples of 8} + {multiples of 12} + {multiples of 18}

- {multiples of 24} - {multiples of 72} - {multiples of 36}

+ {multiples of 72}

= 37 + 25 + 16 - 12 - 4 - 8 + 4 = 58

Is (7,0) a solution to the equation y = x - 2?

Step-by-step explanation:

because 7-7=0 and it doesn't subtract by 2

Answer:

no

Step-by-step explanation:

y = x-2

Let x = 7 and y=0

The ratio of Mitchell's age to Connor's age is 8:5. In thirty years, the ratio of their ages will be 6:5. How much older is Mitchell than Connor now?

Answers

Answer:

9 years older

Step-by-step explanation:

The ratio of their ages is 8 : 5 = 8x : 5x ( x is a multiplier )

In 30 years their ages will be 8x + 30 and 5x + 30 and the ratio 6 : 5 , so

[tex]\frac{8x+30}{5x+30}[/tex] = [tex]\frac{6}{5}[/tex] ( cross- multiply )

5(8x + 30) = 6(5x + 30) ← distribute parenthesis on both sides

40x + 150 = 30x + 180 ( subtract 30x from both sides )

10x + 150 = 180 ( subtract 150 from both sides )

10x = 30 ( divide both sides by 10 )

x = 3

Then

Michell is 8x = 8 × 3 = 24 years old

Connor is 5x = 5 × 3 = 15 years old

Mitchell is 24 - 15 = 9 years older than Connor

Answers

Answer:

IU=161

Step-by-step explanation:

Angle Formed by Two Secants=  1/2 (difference of Intercepted Arcs)

42 = 1/2 (7m+5 - (3m-1))

Distribute the minus sign

42 = 1/2 (7m+5 - 3m+1))

Combine like terms

42 = 1/2 ( 4m+6)

Distribute the 1/2

42 = 2m+3

Subtract 3 from each side

42-3 = 2m+3-3

39 = 2m

Divide by 2

19.5 = m

The sum of the arcs = 360

IU+ 3m-1 + 7m+5 = 360

IU +10m+4 = 360

IU +10(19.5) +4 = 360

IU +195+4 = 360

IU = 360 - 199

IU=161

If LM = 9x + 27 and RS = 135, find x.

Answers

Answer:

x=12

Step-by-step explanation:

LM = RS

9x+27 = 135

Subtract 27 from each side

9x+27-27 =135-27

9x=108

Divide each side by 9

9x/9 = 108/9

x = 12

the boxes are equivalent so the one with a single dash is equal to the other with a single dash.

the one with 2 dashes is equal to the other with 2 dashes so on and so forth

SR=LM

LM=9x+27

RS=135

9x+27=135

so I solve it in my own weird way but you can solve it differently. 135-27=108

108/9=12

so your answer is 12

difference of the roots in terms of p and q.

Answers

Answer:

√(p²-4q)

Step-by-step explanation:

Using the Quadratic Formula, we can say that

x = ( -p ± √(p²-4(1)(q))) / 2(1)  with the 1 representing the coefficient of x². Simplifying, we get

x = ( -p ± √(p²-4q)) / 2

The roots of the function are therefore at

x = ( -p + √(p²-4q)) / 2 and x = ( -p - √(p²-4q)) / 2. The difference of the roots is thus

( -p + √(p²-4q)) / 2 - ( ( -p - √(p²-4q)) / 2)

= 0 + 2 √(p²-4q)/2

= √(p²-4q)
