Answer:

13 of August,

Step-by-step explanation:

All of them worked together at day number zero (August 1).

We know that Elvis works every 3rd day

So he will work at:

day 3, day 6, day 9, etc.

We know that Izzy works every 4th day, then she will work at:

day 4, day 8, day 12, etc.

We know that Janaisa works every 6th day, so she will work at:

day 6, day 12, etc.

We just need to find a day where the 3 of them work, this is equivalent to finding a common multiple of the numbers: 3, 4 and 6.

To do it, we can just write the multiples of each one of these numbers and see which one is the first common multiple:

3)

3*1 = 3

3*2 = 6

3*3 = 9

3*4 = 12

3*5 = 15

...

4)

4*1 = 4

4*2 = 8

4*3 = 12

4*4 = 16

...

6)

6*1 = 6

6*2 = 12

So we can see that 12 is a common multiple of the 3 numbers.

Then they will work together 12 days after August 1th.

That would be the 13 of August,

Answer:

The value of x is 55, because the two angles shown in each diagram are supplementary.

Answer:

A and B ( page 12 and page 20 )

Step-by-step explanation:

1/4 of an hour he read 9 pages ( 15 mins ) ( 60 / 1 hour divided by 4 = 15 ) In other words 9 pages in 15 mins. To get to an hour u gotta multiply by 4. 15x4=60 9x4=36 ( 1 hour of reading is 36 pages read )

60 divided by 3 = 20

36 divided by 3 = 12 for sure it’s A and B

Answer:

Answer:

d. (600 - 81π) units ³

Step-by-step explanation:

Volume of the shaded portion = volume of triangular pyramid - volume of cone

= ⅓*A*h - ⅓πr²h

Where,

A = 15*10 = 150 units²

r = ½(9) = 4.5 units

h = 12

Plug in the values

Volume of the shaded portion = ⅓*150*12 - ⅓*π*4.5²*12

= (600 - 81π) units³

Answer:

Step-by-step explanation:

Let's take a look at the given angle 135°

The sketch of the angle which corresponds to [tex]-\dfrac{3\pi}{4}[/tex] unit circle and can be seen in the attached image below;

The trigonometric ratios are as follows for an angle θ on the unit circle:

Trigonometric ratio           related ratio on coordinate axes

sin θ                                     [tex]\dfrac{y}{1}[/tex]

cos θ                                    [tex]\dfrac{x}{1}[/tex]

tan θ                                     [tex]\dfrac{y}{x}[/tex]

csc θ                                     [tex]\dfrac{1}{y}[/tex]

sec θ                                     [tex]\dfrac{1}{x}[/tex]

cot θ                                      [tex]\dfrac{x}{y}[/tex]

From the sketch of the image attached below;

The six trigonometric ratio for 135° can be expressed as follows:

[tex]sin (-\dfrac{3\pi}{4})= \dfrac{y}{1}[/tex]

[tex]sin (-\dfrac{3\pi}{4})=- \dfrac{\sqrt{2}}{2}[/tex]

[tex]cos (-\dfrac{3\pi}{4})= \dfrac{x}{1}[/tex]

[tex]cos (-\dfrac{3\pi}{4})= -\dfrac{\sqrt{2}}{2}[/tex]

[tex]tan (-\dfrac{3\pi}{4})= \dfrac{y}{x}[/tex]

[tex]tan (-\dfrac{3\pi}{4})= \dfrac{-\dfrac{\sqrt{2}}{2}}{-\dfrac{\sqrt{2}}{2}}[/tex]

[tex]tan (-\dfrac{3\pi}{4})= -\dfrac{\sqrt{2}}{2}} \times {-\dfrac{2}{\sqrt{2}}[/tex]

[tex]tan (-\dfrac{3\pi}{4})= 1[/tex]

[tex]csc (-\dfrac{3\pi}{4})= \dfrac{1}{y} \\ \\ csc (-\dfrac{3\pi}{4})=\dfrac{1}{-\dfrac{\sqrt{2}}{2}} \\ \\ csc=1 \times -\dfrac{2}{\sqrt{2}} \\ \\csc =-\sqrt{2}[/tex]

[tex]sec (-\dfrac{3 \pi}{4})=\dfrac{1}{x} \\ \\ sec = \dfrac{1}{(-\dfrac{\sqrt{2}}{2})} \\ \\ sec = 1 \times -\dfrac{2}{\sqrt{2}} \\ \\ sec = - \sqrt{2}[/tex]

[tex]cot(-\dfrac{3 \pi}{4}) = \dfrac{x}{y} \\ \\ cot(-\dfrac{3 \pi}{4}) = \dfrac{-\dfrac{\sqrt{2}}{2} }{-\dfrac{\sqrt{2}}{2}} \\ \\ cot(-\dfrac{3 \pi}{4})= -\dfrac{\sqrt{2}}{2} } \times {-\dfrac{2}{\sqrt{2}}} \\ \\ cot (-\dfrac{3 \pi}{4}) = 1[/tex]

I got it wrong but it showed me the right answer so, yea

Answer:

Let the length of the sari be xm

cost of

2

1

=Rs 220

then cost of 1m=2(Rs220)=Rs440

Cost of the sari =x(Rs440)=Rs440x

But given that the cost of sari =Rs2640

Implies that

440x = 2640

Implies that

x=

440

2640

x=6

Answer:

A= 63

Step-by-step explanation:

the both sides are equal so it will be 63 and 63

angle c would be 54

Adding all the sides would give 180 as all sides equal 180

A = p(1+r)^t

1600 = p(1+0.08)¹⁰

P = 1600/2.1589

P= 741.12

Answer:

x is 0 or -7

Step-by-step explanation:

[tex]4x^{2} +28x=0\\4x(x} +7)=0\\4x=0 x=0\\x+7=0\\x=-7[/tex]

Answer:

x = {-7, 0}

Step-by-step explanation:

4x^2 + 28x = 0

Divide both sides by 4

x^2 + 7x = 0

Factor out x

x(x + 7) = 0

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

From the zero product rule

x = 0

and

x + 7 = 0

subtract 7 from both sides

x = -7

x = {-7, 0}

Answer: -6.8

Answer:

[tex]3)\ x = 8[/tex]

[tex]4)\ x = 12[/tex]

Step-by-step explanation:

Given

The similar triangles

Required

Solve for x

TUV to TLM implies that, the corresponding sides are:

[tex]TU \to TL[/tex]

[tex]TV \to TM[/tex]

[tex]UV \to LM[/tex]

To solve for x, we use the following equivalent ratios

[tex]TV : TM =TU:TL[/tex]

This gives:

[tex]24 : x + 8=36 : 24[/tex]

Express as fraction

[tex]\frac{24 }{ x + 8} =\frac{36 }{ 24}[/tex]

Cross Multiply

[tex]36(x + 8) =576[/tex]

Divide both sides by 36

[tex]x + 8 =16[/tex]

Subtract 8 from both sides

[tex]x = 8[/tex]

FGH to WVU implies that, the corresponding sides are:

[tex]FG \to WV[/tex]

[tex]FH \to WU[/tex]

[tex]GH \to VU[/tex]

To solve for x, we use the following equivalent ratios

[tex]FH : WU =FG:WV[/tex]

This gives:

[tex]x + 3 : 5 = 27 : 9[/tex]

Express as fraction

[tex]\frac{x + 3 }{ 5 }= \frac{27 }{ 9}[/tex]

[tex]\frac{x + 3 }{ 5 }= 3[/tex]

Cross Multiply

[tex]x + 3 = 3 * 5[/tex]

[tex]x + 3 = 15[/tex]

Subtract 3 from both sides

[tex]x = 12[/tex]

Answer:

Length = 33 m

Width = 11 m

Step-by-step explanation:

l = 3w

2l + 2w = 88

l + w =44

Subsitiute for l

3w + w = 44

4w = 44

w = 11

l = 3(11)

l = 33

Answer:

0.1248 = 12.48% probability of getting 3 blues.

Step-by-step explanation:

The M&Ms are chosen without replacement, which means that the hypergeometric distribution is used to solve this question.

Hypergeometric distribution:

The probability of x successes is given by the following formula:

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]

In which:

x is the number of successes.

N is the size of the population.

n is the size of the sample.

k is the total number of desired outcomes.

Combinations formula:

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

In this question:

7 + 4 + 4 + 2 + 3 + 3 = 23 total M&Ms, which means that [tex]N = 23[/tex]

Sample of 5 means that [tex]n = 5[/tex]

7 blue means that [tex]k = 7[/tex]

What is the probability of getting 3 blues?

This is P(X = 3).

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]

[tex]P(X = 3) = h(3,23,5,7) = \frac{C_{7,3}*C_{16,2}}{C_{23,5}} = 0.1248[/tex]

0.1248 = 12.48% probability of getting 3 blues.
