Answer:

B

Step-by-step explanation:

To calculate the area of this triangle we can use the Heron’s formula

Mathematically we have the Heron’s formula as;

A = √s(s-a)(s-b)(s-c)

where s = (a + b + c)/2

Thus, s = (15 + 12+ 10)/2 = 18.5

a = 15, b = 12 and c = 10

Plugging these values into the equation, we have

√18.5(18.5-15)(18.5-12)(18.5-10)

= √18.5(3.5)(6.5)(8.5)

= √ 3,577.4375

A = 59.8116

which is approximately 59.8 square units

Answer:

3x^2 - 15 = 0

-x^2 + 14 = 0

-2x^2 + 4x - 5 = 0

Step-by-step explanation:

3x^2 = 15

3x^2 - 15 = 0

-x^2 = -14

-x^2 + 14 = 0

4x - 2x^2 = 5

-2x^2 + 4x - 5 = 0

Answer: A = {2, 6 ,6 , 6 , 7 ,9}

Step-by-step explanation:

As the mode is 3, we must have a number that repeats 3 times.

As the median is 6, the number in the middle must be 6

then with this we can construct a set with 3 times the number 6.

Now, knowing that the range is 7. the difference between the larger number and the smaller number is 7, so suppose the larger number is 9 and the smaller number is 2 (9 - 2 = 7)

Then the numbers in our set are:

2 6 6 6 9

lets find the last one.

We know that the mean is 6, then we have

6 = (1/6)*( 2 + 6 + 6 + 6 + 9 + x) = (1/6)(29 + x)

6*6 = 29 + x

36 - 29 = x

x = 7

Then our set is:

A = {2, 6 ,6 , 6 , 7 ,9}

Where the number in the middle is 6, the mean is 6, the mode is 3 and the range is 7

Step-by-step explanation:

it takes to long to explain

Answer:

37 years

Step-by-step explanation:

If the mean age of 5 people in that room was 25 years,

∴ Sum₍₅₎= (25×5)years

              = 125 years

When a person enters that room, the mean age was now 27.

∴ Sum₍₆₎=(27×6) years

              = 162 years

∴ The age of the person who entered the room = Sum₍₆₎ - Sum₍₅₎

                                                                                 = (162-125) years

                                                                                 = 37 years

∴ The age of the person who entered the room is 37 years.

Answer:

The ball is 7 feet above the ground 2 seconds after it is thrown.

Step-by-step explanation:

As per the given statement, we are given a graph of function [tex]f(x)[/tex] where 'x' is time (in seconds) in the current scenario.

Time is plotted on x axis and height of football is plotted on y axis.

[tex]f(x)[/tex] is the height of football according to change in time.

Following are the few things that can be observed from the given curve:

1. Initial Height of football is ~4.8 feet i.e. at 0 seconds of time.

2. Football reaches a maximum height of ~7.2 feet at 1.5 seconds.

3. After 1.5 seconds, the height of football starts decreasing.

Here f(2) means, the height of ball at 2 seconds of time.

It is clearly visible from the given graph that height is 7 feet at 2 seconds.

Please refer to the attached answer image. Height at 2 seconds is marked as point P.

Hence, The ball is 7 feet above the ground 2 seconds after it is thrown.

Answer:

When given a percentage of growth or decay, determined the growth/decay factor by adding or subtracting the percent, as a decimal, from 1. In general if r represents the growth or decay factor as a decimal then: b = 1 - r Decay Factor. b = 1 + r Growth Factor. A decay of 20% is a decay factor of 1 - 0.20 = 0.

Step-by-step explanation:

The growth factor is 1.24, and the decay factor is 0.76 for the 24% growth add one as a decimal and for decay subtract one as a decimal.

It is defined as the factor that represents the increase and decreases in value by that factor. For the growth add one as a decimal and for the decay subtract one as a decimal.

For the growth factor:

F(g) = 1+r

Here r = 24% = 0.24

F(g) = 1+0.24 = 1.24

For the decay factor:

F(d) = 1-r

Here r = 24% = 0.24

F(d) = 1-0.24 = 0.76

Thus, the growth factor is 1.24, and the decay factor is 0.76 for the 24% growth add one as a decimal and for decay subtract one as a decimal.

Answer:

RC1.  5

RC2. 8

RC3. a

RC4. 3

Step-by-step explanation:

So basically what you need to start with is the fact that the second triangle is 2 times larger than the first.

so,

8 = 8

C = 10

A = 6

---------------------------------------------------------------------

the next important part is that the opposite sides of the fraction, when multiplied are equal to each other.

( for example 1/2 = 2/4, because 1*4 = 4 and 2*2 = 4)

RC1. a/3 = C/_

substitute

6/3 = 10/_

3 * 10 = 30

6 * _ =30

30/6 = 5.

Rc2. 4c = 5_

4*10 = 5*_

40/5 = 8

RC3. 3c = 5*_

3*10 = 5*_

30/5 = 6

RC4. 4a = 8*_

4 * 6 = 8*_

24/8 = 3

good luck with your schoolwork/homework!

Step-by-step explanation:

use the Pythagoras' theorem

formula for an ABC triangle( right angled)

AB is height

BC is hypotenuse

CA is length

[tex]BC^{2}[/tex] = [tex]AB^{2}[/tex] + [tex]CA^{2}[/tex]

in your case

AB is 7

BC is 8

CA is unknown so we write x

Answer:

P(red) = .3

P(yellow) = .3

75 cubes in the box

Step-by-step explanation:

The probability has to add to 1

Since the number of red cubes equals the number of yellow cubes the probability has to be the same

.4 + x+x = 1

.4 +2x = 1

2x = 1-.4

2x = .6

Divide by 2

x = .6/2

x = .3

P(red) = .3

P(yellow) = .3

We know that

P(blue) = .4 = number of blue cubes/ total number of cubes

                 .4 = 30/total

                  total = 30/.4

                   total = 75

Answer:

Aloy has $55 initially

Benjamin has $95 initially

Step-by-step explanation:

In this question, given the order in which the money flowed in the question, we want to know how much each of the two had initially.

let what Aloys have be x and what Benjamin has be y.

Together, they had 150

x + y = 150 ••••••••(i)

Aloys mother gave him 40, new money is x + 40, Benjamin spent 10, new money is y-10

the new difference is 10

Thus;

(x + 40)-(y-10) = 10

x + 40 -y + 10 = 10

x+ 40 = y

substitute this into the first equation

x + 40 + x = 150

2x + 40 = 150

2x = 150-40

2x = 110

x = 110/2

x = $55

y = x + 40 = 55 + 40 = $95
