Given data

The Given figure is already a whole number

Say the figure is $495.566

Then we can round this up to the nearest cent by considering the third decimal place

Hence the rounded figure will be

=$495.57

Answer:

0.125

Step-by-step explanation:

For a fair coin, H and T is the same probability. To get zero tails, we need to toss a head, then a head, and again a head - each time we succeed with probability of 0.5, so succeeding 3 times happens 0.5^3 of the time = 0.125

Alternatively, look at all the options:

HHH

HHT

HTH

HTT

THH

THT

TTH

TTT

Only one option has no tails, and because the coin is fair, each option is equally probable, so the probability of HHH is 1/8 = 0.125

Answer:

x=100, hope this helped.

Answer:

Step-by-step explanation:

Sum of all angles of triangle = 180

90 + 50 +10x = 180     {Combine like terms}

  140 + 10x = 180    {Subtract 140 from both sides}

             10x = 180 - 140

             10x = 40 {Divide both sides by 10}

                x = 40/10

x = 4

Answer:

5. 28

6. 6

8. 1,232

9. 2

Step-by-step explanation:

When you know both numerators (the numbers on top) or both denominators (numbers on bottom), you can divide the second by the first and then apply that to the other side. For example, on question five, I divided twenty by fifteen. The answer is 1.33333... or [tex]1\frac{1}{3}[/tex], or [tex]\frac{4}{3}[/tex]. So I multiply 21 by this number and my answer is 28. If visualization helps:

[tex]\frac{15}{21} =\frac{20}{y}[/tex]

Step 1: 20 ÷ 15 = [tex]\frac{4}{3}[/tex] (second number divided by first number, using the side where we know both numbers)

Step 2: 21 × [tex]\frac{4}{3}[/tex] = 28 (y = 28. solved!)

You can do the same thing on question nine, even though the known numbers are on the bottom instead of the top. Fifteen divided by 120, then multiply sixteen by your answer - 0.125 - and you will see that j (i?) = 2 :)

If you have any questions, feel free to ask. Hope this helped!

Step-by-step explanation:

In order to find a linear equation you need the slope and y intercept.

Answer:

The answer is 20 meters squared

base area = side^2 = 2^2 = 4 m^2

base perimeter = (2 x 4) = 8 m

lateral surface = (base perimeter x slant height)/2 = (8 x 4)/2 = 16 m^2

surface area = (base area + lateral surface) = (4 + 16)= 20m^2

Answer:

20m^2

Step-by-step explanation:

base area = side^2 = 2^2 = 4 m^2

base perimeter = 2 x 4 = 8 m

lateral surface = (base perimeter x slant height)/2 = (8 x 4)/2 = 16 m^2

surface area = base area + lateral surface = 4 + 16= 20m^2

Answer:

x = 14

Step-by-step explanation:

Hi,

To begin, distribute the 2 to the x and -9.

So...

2 ( x - 9 ) = 10

2x - 18 = 10

2x = 28

x = 14

I hope this helps :)

Answer:

It is growth if the number in the parenthesis is greater than 1.

It is decay if the number in the parenthesis is less than 1.

For example y = 300[tex](2)^{x}[/tex] is growth and [tex]y = 100(.5)^{x}[/tex] is decay

1. cos(F) = 2. 5/13

tan (F) = 3. 12/5

sin (F) = 1. 12/13

2. Sin (R) = 1. 60/68 = 30/34 = 15/17

cos (R) = 2. 32/68 = 16/34 = 8/17

tan (R) = 3. 60/32 = 30/16 = 15/8

Step-by-step explanation:

Angle 3 is a vertical angle of angle 1 and will always be identical to what angle 1 is.

Angle 2 and angle 4 are supplementary angles to angle 1 and will always be the difference between 180 and what angle 1 is.

For example if angle 1 was 45 degrees, angle 3 would also be 45 degrees and angle 2 and angle 4 would be 180-45 = 135 degrees.

Answer:

PC = 12 , AP = 10

Step-by-step explanation:

For each median the distance from the vertex to the centroid is twice as long as the distance from the centroid to the midpoint, then

(1)

PC = 2 × PF = 2 × 6 = 12

(2)

AP = [tex]\frac{2}{3}[/tex] × AD = [tex]\frac{2}{3}[/tex] × 15 = 2 × 5 = 10

Step-by-step explanation:

Answer: 1/4 0.25  2 out of 8

Step-by-step explanation:

Answer:

first use the equation m = y2 - y1 / x2- x1 to get the slope

m = -2 - 2 = -4

m = 3 + 7 = 10 when there is a negative for x1 it turns positive

the slope is -4/10 or -2/5

now plus the info into the point slope equation

y - y1 = m (x-x1)

this is in point slope form y - 2 = -2/5 (x + 7)

This is how to get it in y-intercept form

y -2 = -2/5x + -2.8

now add -2 on both sides to the -2.8

y = -2/5x (Slope)  + -0.8 y- intercept

Hopefully this is right becuase this is just what i learned

Answer:

The simplest answer is to make the fraction 27/1, using the denominator 1. The number 27 is equal to 27 units. Also it can be written as 54/2 or 81/3 or 108/4 or 135/5, etc. In general you have 27n for the numerator and n for the denominator, where n is an integer greater than zero.

Answer:

1.4 hours

Step-by-step explanation:

Runner A:

Speed = 8.1 mph

Time, = t

Runner B :

Speed = 6.3 mph

Time, = t

Distance apart = 20.16 miles

Distance = speed * time

Distance of Runner A + Distance of runner B = distance apart

8.1t + 6.3t = 20.16

14.4t = 20.16

t = 20.16 / 14.4

t = 1.4 hours

Number of hours, t = 1.4 hours
