What is the area of the figure below?

Answer:

Max is 9 feet above Brett.

Step-by-step explanation:

If you subtract how far Max is below the surface to how far Brett is below the surface you find the difference of how much more above Brett Max is.

This would be the mathematical process:

34-25=9

Max is 9 feet above Brett.

Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.

The operator that performs the arithmetic operation is called the arithmetic operator.

Operators which let do a basic mathematical calculation

+ Addition operation: Adds values on either side of the operator.

For example 4 + 2 = 6

- Subtraction operation: Subtracts right-hand operand from the left-hand operand.

for example 4 -2 = 2

* Multiplication operation: Multiplies values on either side of the operator

For example 4*2 = 8

Given that Brett is 34 feet below the surface and Max is 25 feet below the surface.

Max is more than twice as deep below the surface as Brett,

Thus we can determine this difference by subtracting Max's depth from Brett's.

The mathematical solution would be as follows:

⇒ 34 - 25

⇒ 9

Hence, Max is 9 feet above Brett.

Take a look at the image below.

Answer:

CBE = 112.5 degrees

Answer:

A linear sequence

Step-by-step explanation:

In this sequence, the difference between the first two terms is  70−35=35 , we can check this is correct by finding the difference between the 2nd and 3rd terms, which is  105−70=35 . This means the first difference is 35.

The first difference gives us the number we multiply  n  by, or the quotient of n.

This means we get the nth term as  35n+c .

To get  c , we check the difference between the first term and the number we get when we multiply  n  by  35 , when  n=1 .

This gives us:

35n+c=35  

c=35−35n  

c=35−35(1)  

c=35−35  

c=0  

Once we have  c , we get the nth term of  35,70,105  to be  35n .

Answer:

The numbers are 37, 39 and 41.

Step-by-step explanation:

Let the smallest number be [tex]x\\[/tex].

Then the other numbers will be [tex]x+2, x+4[/tex] (as they are consecutive odd numbers, their difference will be 2).

As per the given statement:

LHS(Left Hand Side) : Sum of five times the smaller number and twice the larger number.

i.e. five times the smaller number = [tex]5\times x[/tex]

twice the larger number = [tex]2 \times (x+4)[/tex]

Their sum:

The Left Hand Side becomes:

[tex]5x+2(x+4)[/tex]

RHS(Right Hand Side):

33 more than six times the median number:

i.e. [tex]6\times(x+2) +33[/tex]

Equating LHS and RHS:

[tex]5x+2(x+4) = 6x+12 +33\\\Rightarrow 7x+8=6x+47\\\Rightarrow \bold{x =37}[/tex]

Therefore, the numbers are 37, 39 and 41.

Answer:

y = 17.5

Step-by-step explanation:

y is directly proportional to x means that

y = k.x

when y=5, x=2 --> k = y/x = 5/2

when x=7

y = k.x = 5/2 . 7 = 35/2 = 17.5

If y is directly proportional to x and y = 5 when x = 2 the value of y is 17.5

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.

Given that  y is directly proportional to x

y = 5 when x = 2

We need to find the value of y when x is 7

To find the value of y when x is 7 we have to construct a proportional formula as below

2/5=7/y

Apply cross multiplication

2y=35

Divide both sides by 2

y=35/2

y=17.5

Hence, If y is directly proportional to x and y = 5 when x = 2 the value of y is 17.5

Answer:

n = 4

Step-by-step explanation:

3 + 4n + n = 2n +15

3 + 5n = 2n + 15

5n - 2n = 15 - 3

3n = 12

n = 12 / 3

  = 4

Answer:

N=4

Step-by-step explanation:

Simplifying

3 + 4n + n = 2n + 15

Combine like terms: 4n + n = 5n

3 + 5n = 2n + 15

Reorder the terms:

3 + 5n = 15 + 2n

Solving

3 + 5n = 15 + 2n

Solving for variable 'n'.

Move all terms containing n to the left, all other terms to the right.

Add '-2n' to each side of the equation.

3 + 5n + -2n = 15 + 2n + -2n

Combine like terms: 5n + -2n = 3n

3 + 3n = 15 + 2n + -2n

Combine like terms: 2n + -2n = 0

3 + 3n = 15 + 0

3 + 3n = 15

Add '-3' to each side of the equation.

3 + -3 + 3n = 15 + -3

Combine like terms: 3 + -3 = 0

0 + 3n = 15 + -3

3n = 15 + -3

Combine like terms: 15 + -3 = 12

3n = 12

Divide each side by '3'.

n = 4

I have  gotten it correct on ED

Answer:

the answer is 9

Step-by-step explanation:

I took the test edg 2020

Answer: (a) [tex]A = x^{2}-7x[/tex]

              (b) x = 12 or x = -5

              (c) Length = 12cm

                   Width = 5cm

Step-by-step explanation: Area of a rectangle is calculated as:

A = length*width

(a) If length = x,

width = x - 7

Then, equation is:

A = x(x - 7)

[tex]A = x^{2} - 7x[/tex]

(b) Solving for x:

[tex]A = x^{2} - 7x[/tex]

[tex]x^{2} - 7x = 60[/tex]

[tex]x^{2} - 7x - 60=0[/tex]

Using Bhaskara to solve equation:

[tex]x = \frac{7+\sqrt{(-7)^{2}-4.1.(-60)} }{2}[/tex]

[tex]x =\frac{7+\sqrt{289} }{2}[/tex]

[tex]x =\frac{7+17}{2}[/tex]

[tex]x_{1} = \frac{7+17}{2}[/tex] = 12

[tex]x_{2}=\frac{7-17}{2}[/tex] = -5

The quadratic equation gives two values for x: x = 12 or x = -5

(c) Dimensions are positive numbers, so the value of x used is x = 12.

As length is x:

length = 12cm

Width is 7 less than length:

width = x - 7

width = 5cm

The rectangle has length of 12cm and width of 5cm.

Answer:

0

Step-by-step explanation:

So we have the function:

[tex]p(x)=(x-1)(x+1)[/tex]

To find p(1), substitute x for 1:

[tex]p(1)=((1)-1)((1)+1)\\[/tex]

Simplify:

[tex]p(1)=(0)(2)\\p(1)=0[/tex]

Thus, p(1) is 0.

Restrictions are that 'a' and 'b' cannot be zero. We could write [tex]a \ne 0[/tex] and [tex]b \ne 0[/tex] as shorthand.

The restrictions are put in place to ensure that you can't divide by zero.

=========================================

Explanation:

The coefficients -12 and 4 divide to -12/4 = -3 which is the coefficient for the answer in the numerator.

The 'a' terms divide to (a^3)/(a^2) = a^(3-2) = a^1 = a. We subtract the exponents to simplify.

The b terms are handled in a similar manner to get (b^5)/(b^7) = b^(5-7) = b^(-2) = 1/(b^2)

Putting all three results together has us end up with (-3a)/(b^2) where neither 'a' nor b are zero to prevent a division by zero error. We cannot have 0 in the denominator.

Answer:

Data Set 1:

Mean= 5.73

Median= 5

Shape of distribution: skewed right

Data Set 2:

Mean: 5.27

Median: 6

Shape of distribution: Skewed left

Step-by-step explanation: Edmentum

The mean of Data set 1 is approximately 5.727 and the median is 5.

The mean of Data set 2 is approximately 5.273 and the median is 6.

The median is defined as the value range. To get it, arrange the numbers in ascending order from smallest to largest, then hide one number on either end until you reach the center.

For Data set 1:

The sum of all values in the dataset is:

5 + 8 + 9 + 6 + 3 + 2 + 10 + 8 + 5 + 4 + 3 = 63

The number of values in the dataset is 11.

The mean of the dataset is:

63 / 11 = 5.727 approx.

Sort the values in ascending order:

2, 3, 3, 4, 5, 5, 6, 8, 8, 9, 10

Since there are 11 values, the median is the middle value, which is 5.

Therefore, the mean of Data set 1 is approximately 5.727 and the median is 5.

The distribution of the dataset seems to be slightly skewed to the right.

For Data set 2:

The sum of all values in the dataset is:

8 + 7 + 3 + 2 + 4 + 6 + 2 + 7 + 4 + 9 + 6 = 58

The number of values in the dataset is 11.

The mean of the dataset is:

58 / 11 = 5.273 approx.

Sort the values in ascending order:

2, 2, 3, 4, 4, 6, 6, 7, 7, 8, 9

Since there are 11 values, the median is the middle value, which is 6.

Therefore, the mean of Data set 2 is approximately 5.273 and the median is 6.

The distribution of the dataset seems to be slightly skewed to the left.

#SPJ2

Answer:

Can you please make it more spicific or add a picture

Step-by-step explanation:

We start with m < A + m < B = m < B + m < C as the given equation. We can rearrange the two terms on the right hand side to get m < A + m < B = m < C + m < B. From here, subtract m < B from both sides to end up with m < A = m < C. The angle B terms go away entirely. This rule I used was the subtraction property of equality. The next rule to use is the symmetric property to go from m < A = m < C to m < C = m < A. This rule is basically where we can flip the two sides of the equation and the equation is the same.

Answer:

Height of building is 115.86 m.

Step-by-step explanation:

This is problem of proportion.

a:b = c:d

____________________________________________________________

height of pole = 3.3 m

length of shadow of pole = 1.36 m

ratio

height of pole: length of shadow of pole = 3.3 : 1.36

________________________________________________

let the height of building= x m

length of shadow of building= 47.75 m

ratio

height of building: length of shadow of building= x: 47.75

ratio in both the cases will be same

thus,

x/47.75 = 3.3 / 1.36

=> x = 3.3 / 1.36 * 47.75 = 115.86

Thus, height of building is 115.86 m.

Answer:

y = -1

Step-by-step explanation:

1y + 14 = -4y + 9

Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Add 4y and subtract 14 from both sides:

1y (+4y) + 14 (-14) = -4y (+4y) + 9 (-14)

1y + 4y = 9 - 14

5y = -5

Divide 5 from both sides:

(5y)/5 = (-5)/5

y = -5/5 = -1

-1 is your answer for y.
