Since the numerator is an even number, you can simply remove half of it.

Answer:

93/100

Step-by-step explanation:

In a group of 100 students, 60 are freshman, 55 are female, and 22 are female freshman. Find the probability that a student picked from this group at random is either a freshman or female

Number of Freshman = 60

Number of female = 55

Number of Freshman female 22

Total number of students = 100

The probability that a student picked from this group at random is either a freshman or female

Thus P(freshman or female) = 60/100 + 55/100 - 22/100 = 93/100

Answer:

(a) 60.45 m2.

(b) 332.475 m^3.

Step-by-step explanation:

(a) area =  length * width

= 9750 * 6200

= 60450000 mm^2

There are 1000*1000 = 1,000,000 mm^2 in 1 m^2 so the area in m^2

= 60.45 m^2.

(b) The height in meters is 5500 / 1000 = 5.5 m

Volume = area of floor * height

= 60.45 * 5.5

= 332.475 m^3.

Answer:

The given line has slope m=1

the perpendicular line MUST have slope -1

Since it MUST eat (-3,2), the intercept formula says

B = y - mx = 2 - (-1)(-3)  = 2 - 3 = -1

so the equation of the perpendicular line that eats point W is

y = -x -1

The lines y=x+3 and it's perpendicular y = -x-1 intersect at

  y = x+3 = -x-1

   2x+3 = -1

  2x = -4

  x = -2

THe intersection point is

(-2,1)

Finally by distance formula,

The distance between (-3,2) and (-2,1) is

 sqrt ( (-3 - -2)^2 + ( 2-1)^2)

= sqrt( (-3 + 2)^2 + (2-1)^2)

 = sqrt( (-1)^2 + 1^2)

  = sqrt ( 1+1)

 = sqrt(2)

Step-by-step explanation:

The distance between line l and the point E (-7, 0) will be;

D = 3.

What is distance between point and line?

The distance between a line ax + by + c = 0 and point (p, q) will be;

D = |ap + bq + c|/√a² + b²

Given that;

Equation of line;

y = -3

And, Point = E (- 7, 0)

Hence, The distance between a line and point is calculated as;

Equation of line;

y = -3

y + 3 = 0

Compare with ax + by + c = 0, we get;

a = 0, b = 1 and c = 3

And, Point = (p, q) = (-7, 0)

Thus, The distance between a line and point is;

D = |0 + 0 + 3|/√0+1

D = 3

So, The distance between line l and the point E (-7, 0) will be;

D = 3.

1) A circle has a diameter of 16 cm. Find its circumference=πd=π×16=16π=50.265=50.27=50cm

Let's see

L=

The arc length with central angle 60° and radius 10 cm is 10.47 cm.

An angle exists the figure formed by two rays, named the sides of the angle, sharing a common endpoint, reaching the vertex of the angle. Angles formed by two rays lie in the plane that includes the rays. Angles are also created by the intersection of two planes. These exist named dihedral angles.

If length of arc with central angle 360° is 2*[tex]\pi[/tex]*r (r-Radius)

Then length of arc with central angle 60° is [tex]\dfrac{2\pi r}{6}[/tex].

That is [tex]\pi[/tex]r/3 =3.14*10/3

                   =10.47 cm

Therefore, the arc length is 10.47 cm.

Answer:

  arc MKL ≈ 19.02 m

Step-by-step explanation:

The figure shows angle KNL is the complement of angle KNJ, so is ...

  ∠KNL = 90° =∠KNJ

  ∠KNL = 90° -52° = 38°

We know that KM is a diameter, so arc MJK = 180°, and ...

  arc MKL = 180° +38° = 218°

In radians, that angle measure is ...

  218° × π/180° rad = 109π/90 rad

An arc length is given by the formula ...

  s = rθ . . . . . where r is the radius and θ is the radian measure of the arc

For this problem, the radius is MN = 1/2MK = 5 m, and the length of arc MKL is ...

  s = rθ

  arc MKL = (5 m)(109π/90) = 109π/18 m

  arc MKL ≈ 19.02 m

Answer:

2.5 years

Step-by-step explanation:

Given data

Principal= Rs 24000

Final amount A= Rs 30000

Rate r= 10%

The simple interest expression is

A=P(1+rt)

substitute

30000=24000(1+0.1*r)

30000=24000+2400t

30000-24000=2400t

6000=2400t

t= 6000/2400

t=2.5

Hence the time is 2.5 years

Answer:

Step-by-step explanation:

It x=2

The value of the angles should be. (x-40°). , (x-20°), (½x-10°) , not (x-40°) + (x-20°)+(½x-10°)

Sum of all the interior angles of a triangle is 180°.

So a equation can be made by the given data,

(x-40°) + (x-20°) + (½ x-10°) = 180°

x-40°+x-20°+½x-10° = 180°

2x+½x -60°-10° = 180°

5/2 x - 70° = 180°

5/2 x = 180° + 70°

5/2 x = 250°

x = 250° × 2/5

x = 50° × 2

x = 100°

So the angles are

x-40° = 100°-40° = 60°

x-20° = 100°–20° = 80°

½x-10° = ½(100)° - 10° = 50° -10° = 40°

The answer can be checked by putting the values of the angle we got in the second statement i.e. Sum of all the interior angles of a triangle is 180°.

60° + 80° + 40° = 100° + 80° = 180°

Answer:

Option D

Step-by-step explanation:

For addition we move right on the number line and for subtraction we move left.

So, (-7) represents a 7 units to the left from the zero.

Then move 10 units right from (-7),

Therefore, (-7) + 10 = 3

Or (-7) - (-10) = 3

Option D is the correct option.

Answer:

1 quarts of red paint

2.4 quarts of blue paint

Step-by-step explanation:

Let :

a = quarts of blue paint

b = quarts of red paint

a + b = 3 2/5

a + b = 3.4 - - - (1)

Ratio of a and b :

a/b = 4/5 ÷ 1/3 = 4/5 * 3/1 = 2.4

a/b = 2.4

a = 2.4b - - (2)

From (1)

2.4b + b = 3.4

3.4b = 3.4

b = 1

a + b = 3.4

a + 1 = 3.4

a = 3.4 - 1

a = 2.4

a + a + a is the same as multiplying a by 3 so you would have 3a

b + b is the same as multiplying b by 2 so you would have 2b

Combing everything together you would have the final answer of :

3a + 2b + c

Step-by-step explanation:

20 is 16% of what number?

20 = .16n

n = 20/.16 = 125

Answer:

A= $1406

Step-by-step explanation:

The formula for simple interest is A=P(1+rt), where P=Principal, R=Rate, and T=Time. Before you plug your numbers into your formula, you must first convert 12% to a decimal (This is simple because all you have to do is divide 12 by 100.)- 0.12.

Now, you can plug your numbers into the formula: A=950(1+0.12x4). To make this less complex, I suggest working in the parenthesis first- specifically simplifying rt, or multiplying 0.12 by 4 (you should get 0.48)! Now, you are just about ready to go. A=950(1+0.48)- You can plug this into your calculator as is, or you can go on ahead and add the numbers in the parenthesis if that makes you feel better! (You should get 1.48).

Your final formula should be 950(1.48), and you should plug this into a TEACHER-APPROVED CALCULATOR to save time!

Your final answer should be $1406, otherwise you did something wrong! XD!
