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:

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

tan (F) = 3. 12/5

sin (F) = 1. 12/13

Answer:

8m

Step-by-step explanation:

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:

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

Step-by-step explanation:

Answer:

option 3)

14% approx

Step-by-step explanation:

Given data

Initial= $18.00

final =$20.50

% increase= final - initial/initia *100

% increase= 20.50-18.0/18*100

% increase=2.5/18*100

% increase=0.138*100

% increase=13.8%

Hence the increase is 13.8%

=14% approx

Answer:

I am sorry but i do not have any information in order to answer this question

Step-by-step explanation:

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

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:

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

Step-by-step explanation:

Answer:

[tex]-\frac{17}{4}[/tex] is 27th term of the given sequence.

Step-by-step explanation:

Given sequence is [tex]2\frac{1}{4},2,1\frac{3}{4},......[/tex]

Here, first term of the sequence,

[tex]a_1=2\frac{1}{4}[/tex]

By subtracting first term from the second term of the sequence,

[tex]T_2-T_1=2-2\frac{1}{4}[/tex]

            = [tex](2-2)-\frac{1}{4}[/tex]

            = [tex]-\frac{1}{4}[/tex]

Similarly, difference in second and third term,

[tex]1\frac{3}{4}-2=(1-2)+\frac{3}{4}[/tex]

           = [tex]-1+\frac{3}{4}[/tex]

           = [tex]\frac{3-4}{4}[/tex]

           = [tex]-\frac{1}{4}[/tex]

Therefore, there is a common difference (d) of [tex](-\frac{1}{4})[/tex].

Hence, the sequence is an Arithmetic sequence.

Explicit formula of an Arithmetic sequence is given by,

[tex]T_n=a_1+(n-1)d[/tex]

Here, n = number of term

If, [tex]T_n=-\frac{17}{4}[/tex]

By substituting these values in the formula,

[tex]-\frac{17}{4}=2\frac{1}{4}+(n-1)(-\frac{1}{4})[/tex]

[tex]-\frac{17}{4}-2\frac{1}{4}=(n-1)(-\frac{1}{4})[/tex]

[tex]-\frac{17}{4}-\frac{9}{4}=-(n-1)(\frac{1}{4})[/tex]

[tex]-(\frac{17+9}{4})=(n-1)(\frac{1}{4})[/tex]

[tex]\frac{26}{4}=\frac{1}{4}(n-1)[/tex]

n - 1 = 26

n = 27

Therefore, [tex]-\frac{17}{4}[/tex] is 27th term of the given sequence.

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

Answer:

4/5 of 90 is 72°

supplement=angle1+angle 2= 360°

so if 1 angle is 72°

then the other angle is 360-72=288°

Step-by-step explanation:

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:

x=100, hope this helped.

Answer:

21

Step-by-step explanation:

add both and make it equal to 180

9x-9=189

x=21

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

Step-by-step explanation:

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:

(x+10)+(×+50)=180(exterior co- interior angel

2x+60=180

2×=180-60

×=120/2

×=60

(6x+3)=(7x-12)(corresponding angle )

3+12=7×-6×

x=15

4x-2=3x-19(vertically opposite angle)

4x-3×=-19+2

x=-17

Mark me brainiest please and this is for K12

Answer: It's the second answer. Subtract 22 from 50, then divide the result by 3.

Step-by-step explanation: 3x+22= 50. You need to subtract 22 to both sides which will become 3x=28. Then you need to divide each side by 3, and the answer is 9.3 (With 3 repeating).
