Answer:

Irrational numbers are numbers that cannot be expressed as the ratio of two whole numbers. This is opposed to rational numbers, like 2, 7, one-fifth and -13/9, which can be, and are, expressed as the ratio of two whole numbers.

Answer:

880 cm²

Step-by-step explanation:

Given that :

Curved surface area of a cone : πrl

r = base Radius = 14 cm

l = slant height = 20 cm

Hence,

Curved surface area = π * 14 * 20

Curvwd surface are = π * 14 * 20

Curved surface area = 879.64594 cm²

Curved surface area = 880 cm²

Answer: The angles are vertical. The value of x=25

Step-by-step explanation:

4x-25=75

 +25  +25

4x=100

/4    /4

x=25

I hope this help you! :)

Step-by-step explanation:

Evelyn: Y=89x + 19

Brenda: Y=87x + 21

Punch in numbers for X until you get the same for both. Remember that X is hours and Y is total. the numbers with no letters is the fixed booking amount. cheers. Good luck :)

Answer:

First two (S = 9.20   K = 10.15)

Step-by-step explanation:

Hours = x

Money Earned (AED) = y

Shamael

y = 9.2x

AED = 9.2(hours)

$9.20 an hour

Kamla

y = kx

  ([tex]x_{1} ,y_{1}[/tex]) = (5, 50.75)

  ([tex]x_{2}, y_{2}[/tex]) = (4, 40.60)

  k = [tex]\frac{y_{1}-y_{2}}{x_{1}-x_{2}}[/tex] = [tex]\frac{50.75-40.60}{5-4}[/tex] = [tex]\frac{10.15}{1}[/tex] = 10.15

AED = 10.15(hours)

$10.15 an hour

4 (CIE 2012, w, paper 22, question 8)

Step-by-step explanation:

Answer:

The length has increased by a factor of 4/3 or 1 1/3

Step-by-step explanation:

To find the initial length.: root 36.

Root 36 = 6

Then to find the increased version, first find the area: 36 + 28 = 64

Now, the length.

Root 64 = 8

To find the factor it increased by:

6x = 8

x = 8/6 = 4/3

The length has increased by a factor of 4/3 or 1 1/3

Answer:

.10 + 11u or 11u + 10

Step-by-step explanation:

combine like terms:

. 5u + 6u = 11u

. 9 + 1 = 10

Answer:

10+11u

Step-by-step explanation:

9+5u+6u+1

1. add the numbers that are the same. 9+1= 10

2.do the same thing to the other number(s) 5u+6u= 11u

3. add both you're answers together 10+11u

1.88*10^10 miles

Step-by-step explanation:

(430,000m/h)*(24 hours/ 1 day)*(365 days/ 1 year)*(5years)

Everything but miles cancels out,

430,000*(24*365*5) = 18,834,000,000miles

Or, 18.8 billion miles

Or, 1.88*10^(10) miles

Answer:

3052.08

Step-by-step explanation:

since there is nothing next to the hundredths place its 3052.08, unless your taking about the hundreds place then it would be 3100.00.

Answer:

it's the second choice (3=3)

Answer:

y = - x + 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (1, 3) and (x₂, y₂ ) = (3, 1)

m = [tex]\frac{1-3}{3-1}[/tex] = [tex]\frac{-2}{2}[/tex] = - 1 , then

y = - x + c ← is the partial equation

To find c substitute (1, 3 ) into the partial equation

3 = - 1 + c ⇒ c = 3 + 1 = 4

y = - x + 4 ← equation of line

Answer:

A 180° angle is called a straight angle. Angles such as 270 degrees which are more than 180 but less than 360 degrees are called reflex angles. A 360° angle is called a complete angle.

Answer:

A. 4

B. 2

C. 3

D. 2

Step-by-step explanation:

Multiplication!!! Always remember that a right angle is 90 degrees, also a straight angle is 180 degrees..

Remember like this:

90 x 1 =90

90 x 2 =180

90 x 3 = 270

90 x 4 = 360

71.78? (not sure)

Step-by-step explanation:

To find 3% of 74, 74*.03 = 2.22

Subtract 3%, 74-2.22 = 71.78

Answer:

Answer is B

Step-by-step explanation:

SohCahToa

[tex]tan = \frac{o}{a} [/tex]

Hypotenuse : Opposite the right angle. : 13

Opposite : Opposite the B angle : 5

Adjacent : The only side left : 12

we need opposite and adjacent, hypotenuse is irrelevant in this question.

Substitute the numbers

[tex]tan( \frac{5}{12} )[/tex]

Answer: 54 square feet

Step-by-step explanation:

To find perimeter of a rectangle we must use the formula l+l+w+w=p where l and w represent width and length

Since we know length and width is x=12 just substitute so

15+15+12+12=54 so 54 is the perimeter
