-Lemony Snicket

Answer:

Hema - 9 stickers Rekha - 21 stickers

Step-by-step explanation:

Total Number of stickers given - 30

Ratio of stickers divided between Hema and Rekha - 3:7

Let the number of stickers Hema have be 3x

Let the nunber of stickers Rekha have be 7x

According to question,

3x+7x=30

10x=30

x=30/10

x=3

Therefore,

Number of stickers Hema got = 3x

= 3*3

= 9

Number of stickers Rekha got = 7x

= 7*3

= 21

Hence,

Hema will get 9 stickers

Rekha will get 21 stickers

Answers:

24 quarters

22 nickels

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

Work Shown:

q = number of quarters

n = number of nickels

q+n = 46 coins total which solves to n = 46-q

25q = value of all the quarters in cents

5n = value of all the nickels in cents

25q+5n = value (cents) of all the coins of both types

25q+5n = 710 cents total = $7.10

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

Apply substitution.

25q+5n = 710

25q+5(46-q) = 710

25q+230-5q = 710

20q+230 = 710

20q = 710-230

20q = 480

q = 480/20

q = 24

They have 24 quarters

This yields 25*q = 25*24 = 600 cents = $6.00 so far.

Use that value of q to find n

n = 46-q

n = 46-24

n = 22

They also have 22 nickels.

They have an additional 5n = 5*22 = 110 cents = $1.10

In total, they have 6.00+1.10 = 7.10 dollars which confirms we have the correct coin counts. Also, q+n = 24+22 = 46.

[tex]i^{157} = i\\\\i^{315} = -i\\\\i^{102} = -1\\\\i^{76} = 1\\\\[/tex]

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

Explanation:

By definition, [tex]i = \sqrt{-1}[/tex]

Squaring both sides gets us [tex]i^2 = -1[/tex]

Then multiply both sides by i to get [tex]i^3 = -i[/tex]

Repeat the last step and you should get [tex]i^4 = -i^2 = -(-1) = 1[/tex]

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

Notice we have this pattern going on:

[tex]i^0 = 1\\\\i^1 = i\\\\i^2 = -1\\\\i^3 = -i\\\\i^4 = 1\\\\[/tex]

Once we reach i^4, we start the process over again.

It repeats every 4 terms.

This means we'll divide the exponent over 4 and look at the remainder. We ignore the quotient completely.

157/4 = 39 remainder 1

That remainder 1 is the exponent of the simplified term

[tex]i^{157} = i^1 = i[/tex]

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

Similarly,

315/4 = 78 remainder 3

So [tex]i^{315} = i^3 = -i[/tex]

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

102/4 = 25 remainder 2

[tex]i^{102} = i^2 = -1[/tex]

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

76/4 = 19 remainder 0

[tex]i^{76} = i^0 = 1[/tex]

4:7

Step-by-step explanation:

The ratio of the number of corn tortillas to flour tortillas is 3:4. So this means there are at least 3 corn tortillas and 4 flour tortillas.

We need to add 3 and 4 to see the simplified total of tortillas. 3+4=7.

There is a total of 7 tortillas regardless of their type.

Now we just need to compare this with the number they already gave us for flour tortillas, which is 4.

4:7 or 4 flour:7 in total

The ratio of flour tortillas to total tortillas is 4:7.

[tex]\cos(2\theta)=cos^2(\theta)-sin^2(\theta)[/tex]

Jouc ÷4 i for number 69263

hope it helps

Answer:

Step-by-step explanation:

Place : y+x=2 <==> y = 2-x

and now replace y with the x-expression:

2x-(2.x)=-4 <==> 2x-2+x= 4 <==> 3x-2 =4 <==> 3x = 6 --> x = 2

and y = 2-x so y = 2-3 = -1

so the solution is S = {(2; .1)}

Answer should be:

y = -3x - 3

Answer:

The equation is y = - 3x - 3

Step-by-step explanation:

Step 1:

Equations always start with y = (unless you are in grade 11) in which case you start with f(x) =

Step 2:

Use rise over run to find the slope (since its based on graph, if not there is a formula to find it when given coordinate points only)

So to use rise over run, you count how many squares upwards starting from a point that aligns in the graph (in this case the bolded dots)

So you start at (-2, 3) and count how many squares up or down to the next bolded dot (if its up its positive, if you have to go down then its negative).

Then once youve reached the same y-value as the the other dot, count how many squares to the right.

So in this case, you have to go down 6 times and right 2 times.

So as a fraction its -6/2 but that can be simplified to just -3

So thats the slope: -3

Step 3

then you need to find the y-intercept (where the line touches the y-axis)

Its easy: you can visually see that the line crosses at -3.

and the format for the equation is y = mx + b

m = slope

b= y-intercept

SO: y= -3x - 3

Answer:

1: y=-2x+5

Step-by-step explanation:

When two lines are parallel, the slopes are equivalent.

First, you have to turn 2x+y=7 into standard form.

2x+y=7

y=-2x+7

The slope is -2 so then you find an answer choice with -2 as the slope.

Turn all the answers into standard form first:

2: x+2y=4

2y=-x+4

y=-1/2x+4  Not choice 2 since the slope is -1/2.

3: y-2x=2

y=2x+2 Not choice 3 because the slope is positive 2.

Therefore, choice 1 is parallel to equation 2x+y=7.

Answer:

value of a is -19

value of b is 10

Step-by-step explanation:

Given

p(x) = 6x³ + ax² + 9x + b

Since it is given (x-2) & (2x-1) are the factors of given polynomial p(x) .

So, x = 2 & x = -1/2 are the solutions of given polynomial .

when x = 2

p(2) = 6(2)³ + a(2)² + 9 (2) + b = 0

p(2) = 6×8 + 4a + 18 + b = 0

p(2) = 48 + 4a + 18 + b = 0

p(2) = 66 + 4a + b = 0

4a + b = -66 -------(i)

Now ,

when x = -½

p(-½) = 6(-½)³ + a (-½)² + 9(-½) + b = 0

6 × (-⅛) + a/4 - 9/2 + b = 0

-3/4 + a/4 - 9/2 + b = 0

-3 + a -18+4b/4 = 0

-21 + a + 4b = 0

a + 4b = 21 -------(ii)

Now, multiplying the equation (ii) by 4 we get

4a + 16b = 84 -----(iii)

Substracting equation (i) from (iii) we obtain

15b = 150

b = 150/15

b = 10

Now, putting the value of b = 10 in equation (ii) we get

a + 40 = 21

a = 21-40

a = -19

So, the required value of a & b are 10 & -19 respectively .

Answer:

3

Step-by-step explanation:

N*(2/3)=4

N=4*(3/2)=6

1/2 of N is 3

If the 2/3rd fraction of N is 4, then 1/2 fraction of N is 3.

Fractions are representations of equal parts of a whole number.

It is written as a/b, read as "a by b", and represents 'a' equal parts of 'b' equal parts.

'a' is called the numerator, and 'b' is called the denominator.

In the question, we are asked if 2/3 N is 4, then what is 1/2 of N.

We can represent the first fractional expression as:

2/3 of N = 4.

Now, we will solve the above expression by replacing of with multiplication.

2/3 * N = 4,

or, 2N/3 = 4.

Now, we will cross-multiply to get:

N = (4*3)/2 = 6.

Now, we are asked to find 1/2 of N.

We simply multiply (1/2) to the value of N:

(1/2)*N = (1/2)*6 = 3.

Thus, if the 2/3rd fraction of N is 4, then 1/2 fraction of N is 3.
