Nasreen bought 3 m 20 cm cloth for her shirt and 2 m 5 cm cloth for her trouser. Find the total length of cloth bought by her.

Step-by-step explanation:

the easiest approach seems to be the law of sines :

a/sin(A) = b/sin(B) = c/sin(C)

where the sides and the angles are always opposite of each other.

we have here a right-angled triangle, so the angle opposite of 10 is 90 degrees.

10/sin(90) = 10/1 = 10 = y/sin(37)

y = 10×sin(37) = 6.018150232 ≈ 6.0

Step-by-step explanation:

but then you did already the most work.

because just think : when is the expression

(x+3)(x+2) equal to 0 ?

only, if at least one factor of the multiplication is equal to 0.

you know, for example, 5×0 = 0, or 0×3 = 0.

that means either (x+3) or (x+2) must be 0.

x + 3 = 0

x = -3

and

x + 2 = 0

x = -2

and there you have it.

a quadratic equation (with the highest x exponent is 2) has 2 solutions for being 0.

and this one here has the 2 solutions

x = -3 and

x = -2

again, by finding the factors you did already the biggest and most difficult part yourself. congratulations !

Answer:

p = 2a + 2b

Step-by-step explanation:

The perimeter p is the sum of the 4 sides , then

p = a + a + b + b = 2a + 2b

Answer:

x = -5

y = -6

Step-by-step explanation:

5x - 6y = 11

-7x + 5y = 5

We could eliminate the 'y' by multiplying the first equation by 5 and the second equation by 6 to get the following:

5(5x - 6y) = 11(5)     → 25x - 30 y = 55

6(-7x + 5y) = 5(6)    → -42x + 30y = 30

Now we can add the two equations to get:

-17x = 85

x = -85/17 which is x = -5

Now we can plug in -5 into the first equation to solve for 'y':

5(-5) - 6y = 11

-25 - 6y = 11

-6y = 36

y = -6

CHECK:

-7(-5) + 5(-6) should equal 5

35 + (-30) = 5

5 = 5

Answer:

1 pound of gummy bears = $3.20

1 pound of jelly beans = $7.50

Step-by-step explanation:

1.8 pounds of gummy bears + 0.6 pounds of jelly beans

= $10.26

1.2 pounds of gummy bears + 1.5 pounds of jelly beans

= $15.09

2.5 × (1.8 pounds of gummy bears + 0.6 pounds of jelly beans) = 2.5 × $10.26

--> 4.5 pounds of gummy bears + 1.5 pounds of jelly beans = $25.65

(4.5 pounds of gummy bears + 1.5 pounds of jelly beans) - (1.2 pounds of gummy bears + 1.5 pounds of jelly beans) = 3.3 pounds of gummy bears

3.3 pounds of gummy bears

= $25.65 - $15.09

= $10.56

1 pound of gummy bears

= $10.56 ÷ 3.3

= $3.20

1 pound of jelly beans

= [$10.26 - ($3.20 × 1.8)] ÷ 0.6

= $4.50 ÷ 0.6

= $7.50

Answer:

Step-by-step explanation:

First term in the sequence is given as 30. The common difference (difference between first term and next term) is -7. Since we are looking for the 12th term we can do 30 - (11 * -7) = -47. It's 11 * -7 because we already are given one term in the problem statement.

Answer:

13/15

Step-by-step explanation:

"Or" in probability means to add. Therefore, we would do 2/3 + 1/5:

First, we need a common denominator: 2/3 + 1/5 → 10/15 + 3/15 (I multiplied the first fraction by 5/5 and the second fraction by 3/3).

Now, we can add the numerators: 10/15 + 3/15 = 13/15.

Answer:

y=2x+7

Step-by-step explanation:

you would substitute so x=-2 and y=3

All lines parralel always have the same x so

y=2x-c (c means crossing point of y)

then substitute

3=(2x-2)-c

3=-4-c

c= +7

so just put in the equation and the answer is:

y=2x+7

Step-by-step explanation:

[tex]81x^{3}-36x[/tex]

9(9x³ - 4x)

9x(9x² - 4)

Since both terms are perfect squares factor using the difference of squares formula,  a² - b² = (a + b) (a - b)

Answer:

81z^3-36z = 9z(3z-2)(3z+2)

Step-by-step explanation:

(81z^3-36z)=9z(9z^2-4)

9z(9z^2-4)=9z(3z-2)(3z+2)

81z^3-36z=9z(3z-2)(3z+2)

81z^3-36z=9z(3z-2)(3z+2)

Answer:

Step-by-step explanation:

First things first, you need to find out how many minutes it took Corrine to run one mile each day. To do this, you divide 4 by 4 and 28 by 4

4 ÷ 4 = number of miles

4 ÷ 4 = 1 mile

28 ÷ 4 = number of minutes for one mile

28 ÷ 4 = 7 minutes for one mile

Next, you need to divide 5.5 by 5.5 and 32 by 5.5

5.5 ÷ 5.5 = number of miles

5.5 ÷ 5.5 = 1 mile

32 ÷ 5.5 = number of minutes for one mile

32 ÷ 5.5 = 5.81818181818

So, Corrine ran one mile in 7 minutes yesterday and ran one mile in 5.81818181818 today.

All in all, Corrine ran faster today than yesterday.

Since the probabilities must add up to 1, we have to solve this equation :

1/5 + 1/5 + 1/2 + x = 1

2/5 + 1/2 + x = 1

4 / 10 + 5 / 10 + x = 1

9/10 + x = 1

x = 1 - 9/10

x = 10/10 - 9/10

x = 1/10

So the value of x is 1/10

Option A is correct, the value of x should be 1/10.

It is a branch of mathematics that deals with the occurrence of a random event.

In a valid probability distribution, the sum of all probabilities must be equal to 1.

We know that the given probability distribution is 1/5, 1/5, 1/2, x. Therefore, we can write an equation:

1/5 + 1/5 + 1/2 + x = 1

Simplifying the equation, we get:

2/5 + x = 1/2

Subtract 2/5 from both sides

x=1/2-2/5

x=5-4/10

x=1/10

Hence, option A is correct, the value of x should be 1/10.

Step-by-step explanation:

1) 4, -3, -10, -17,...

d = -3 - 4 = -7 or -10 - (-3) = -7

Arithmetic , d = -7

2) 4, 8, 16, 32,...

d = 8 - 4 = 4, 16 - 8 = 8,
