Answer:

if your base is 14 and your height is 18 or the other way around then its:

14 x 18 = 252

252 divided by 2 = 126

Step-by-step explanation:

Formula of a triangle:

BH x 1/2 (basically dividing by 2)

B is your base which is the length on the bottom of the triangle and the height is the line that is put in between the triangle. You multiply those then divide by 2 since your multiply 2 with it.

Answer:

21

Step-by-step explanation:

add both and make it equal to 180

9x-9=189

x=21

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

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

18+1.08=19.08

Answer:

Ralph walked to Sherwood at a constant speed.

Step-by-step explanation:

Any horizontal lines on a distance time graph represent a moment where you are still, so that rules out graph 4 and graph 3. Because Ralph is at a constant speed, the gradient of the line won’t change, meaning the answer has to be Ralph walked to Sherwood at a constant speed.

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

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:

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. 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:

1 picture:

sin = Opp/Hyp

cos = adj/hyp

Answer:

Length = 75 ft

Width = 72 feet

Volume = 32,400 ft3

Water is around 242,998 gallons

Step-by-step explanation:

Just convert the yards to feet

25 yards long = 75 ft in length

8 lanes * 3 yards wide = 24 yards = 72 feet wide

And then for the volume, since it's a swimming pool, the formula will be l*w*h, and if we plug in the numbers (75 * 72 * 6 (it's 6 because they said the depth was six and in a pool the depth = height)) and that'll equal 32,400 ft to the third power

For the water, we just have to multiply the volume by 7.5 gallons by converting 7.5 gallons to feet, and then multiplying that by the volume, and then converting that to feet, and the final answer is about 242,998 gallons

Answer:

Length; 75 ft  

Width; 72 feet  

Volume; 32,400  

Water is around 243k gallons

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

Step-by-step explanation:

Area of a rectangle = length x width

8/3 x 3/4 = 2

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!

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:

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

The answer u have is the answer for a^2

Answer:

Root (c square -9)

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
