What is the base of a triangle with an area of 207 in.² and a height of 18 inches

Answers

Answer 1

We just need to divide so we can find the base length of the triangle:

207 / 18 = 11.5

Therefore, the base length of the triangle is 11.5 inches.

Best of Luck!

Answer 2

Answer:

23 inches

Step-by-step explanation:

A = [tex]\frac{1}{2}[/tex] bh

207 = [tex]\frac{1}{2}[/tex] b x 18

[tex]\frac{207}{9}[/tex] = b

b = 23

You can replace u with -3 since u = -3. You should get something like this: -3 - 4(-3) + 3. This can be turned into -3 + 12 + 3, and subtracting negative numbers are the same as adding the positive version. -3 plus 12 is 9, and 9 plus 3 is 12. The final answer is 12. Hope this helps!

How do you do this question?

Answers

Answer:

9.29

Step-by-step explanation:

S₄ is the area using Simpson's rule and 4 intervals.

Simpson's rule can be calculated as:

Sᵢ = Δx/3 (f(x₀) + 4f(x₁) + 2f(x₂) + 4f(x₃) + ... + 4f(xᵢ₋₂) + 2f(xᵢ₋₁) + f(xᵢ))

Or, Simpson's rule can be calculated as a combination of midpoint and trapezoid sums:

S₂ᵢ = (2Mᵢ + Tᵢ) / 3

Using the first method:

Δx = (4−0)/4 = 1

S₄ = 1/3 (1.00 + 4(1.41) + 2(2.24) + 4(3.16) + 4.12)

S₄ = 1/3 (27.88)

S₄ ≈ 9.29

Using the second method:

S₄ = (2M₂ + T₂) / 3

The midpoint area for 2 intervals is:

M₂ = (2) (1.41) + (2) (3.16) = 9.14

The trapezoid area for 2 intervals is:

T₂ = ½ (1.00 + 2.24) (2) + ½ (2.24 + 4.12) (2) = 9.60

Therefore:

S₄ = (2 (9.14) + 9.60) / 3

S₄ ≈ 9.29

Find the midpoint of the segment with the following endpoints.
(-6, -6) and (4, -2)

Answers

(-1,-4) Just find the middle of the x coordinates, and the middle of the y coordinates.

Answer:

(-1,-4)

Step-by-step explanation:

USE A1 + A2 / 2 AND B1 + B2 / 2

A1 + A2 / 2

= (-6+4) / 2

= -2/2

= -1

B2 + B1 / 2

= (-6+(-2)) / 2

= -8 / 2

= -4

therefore, (-1,-4) is your midpoint.

Alkena and Hsu together earn $84,369 per year, If alkena earns $12,468 more per year than Hsu, the how much of them earn per year?

Answers

Answer:

Hsu makes $35,950.50 and Alkena makes $48,418.50

Step-by-step explanation:

Create a system of equations, where h is the amount Hsu makes and a is the amount Alkena makes:

a + h = 84,369

a = h + 12,468

Solve by substitution by plugging in h + 12,468 as a:

h + 12,468 + h =  84,369

2h + 12,468 = 84,369

2h = 71,901

h = 35,950.50

Plug this into the equation, a = h + 12,468 , to solve for a

a = 35,950.50 + 12,468

a = 48,418.50

So, Hsu makes $35,950.50 and Alkena makes $48,418.50

The height of a door is 1.4 feet more than 2.3 times its width. If the height of the door is 8.5 feet, which equation can be used to determine x, the width of the door.

Answers

Answer:

[tex]2.3x+1.4=8.5[/tex], width = 3.087 feet.

Step-by-step explanation:

Let as consider width of the door be x feet.

It is given that height of a door is 1.4 feet more than 2.3 times its width. So,

[tex]Height=2.3x+1.4[/tex]

The height of the door is 8.5 feet.

[tex]2.3x+1.4=8.5[/tex]

Therefore, the required equation is [tex]2.3x+1.4=8.5[/tex].

[tex]2.3x=8.5-1.4[/tex]

[tex]2.3x=7.1[/tex]

[tex]x=\dfrac{7.1}{2.3}[/tex]

[tex]x\approx 3.087[/tex]

So, the width of the door is about 3.087 feet.

Which of the following is an odd function? f(x) = 3x2 + x f(x) = 4x3 + 7 f(x) = 5x2 + 9 f(x) = 6x3 + 2x

Answers

The odd function from the following function is f(x) = 6x³ + 2x.

What is an odd function?

The function f(x) is said to be an odd function if the output value of f(-x) is the same as the negative of f(x) for all values of x in the domain of f.

f(-x) = -f(x)

The functions are given below.

f(x) = 3x² + x

f(x) = 4x³ + 7

f(x) = 5x² + 9

f(x) = 6x³ + 2x

f(x) = 3(-x)² + (-x) = 3x² - x

f(x) = 4(-x)³ + 7 = -4x³ + 7

f(x) = 5(-x)² + 9 = 5x² + 9

f(x) = 6(-x)³ + 2(-x) = -6x³ - 2x = - (6x³ + 2x)

Toss 3 dice. What's the probability that a 4 will come up exactly twice?

Answers

Answer:

[tex]\bold{\dfrac{1}{12}}[/tex]

Step-by-step explanation:

The dice is rolled 3 times.

To find:

The probability that a 4 will come up exactly twice = ?

Solution:

Let 4 comes up exactly twice, let the third number be [tex]x[/tex].

The possible outcomes can be:

([tex]x[/tex], 4, 4) where [tex]x[/tex] can be any number between 1 to 6 , so 6 outcomes.

(4, [tex]x[/tex], 4) where [tex]x[/tex] can be any number between 1 to 6 , so 6 outcomes.

(4, 4, [tex]x[/tex]) where [tex]x[/tex] can be any number between 1 to 6 , so 6 outcomes.

So, the total number of favorable outcomes possible = 6 + 6 + 6 = 18

Total number of outcomes that can be possible at roll of 3 dice:

6 [tex]\times[/tex] 6 [tex]\times[/tex] 6  = 216

Formula for probability of an event E is given as:

[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}[/tex]

[tex]P(\text{exact 2 fours}) = \dfrac{18}{216}\\\Rightarrow \bold{P(\text{exact 2 fours}) = \dfrac{1}{12}}[/tex]

Which statement is true about the expression 12 minus 7 + 3? The expression is equivalent to 12 minus (7 + 3) because of the associative property. The expression is equivalent to 12 + 3 + (negative 7) because of the associative property. The expression is equivalent to 12 minus 3 + 7 because of the commutative property. The expression is equivalent to 12 + 3 + (negative 7) because of the commutative property.

Answers

Answer:

The Expression is equivalent to 12+3+ negative 7

Step-by-step explanation:

When you sub tract something for example 5-3 the three can be looked at as a negative number. 5-3=2 but 5+ (-3)=2 as well

The associative property indicates that the true statement about the expression is the option;

''The expression is equivalent to 12 + 3 + (negative 7) because of the associative property''

What is the associative property?

The associative property is related to the grouping of the numbers in an operation. According to the associative property changing the grouping of numbers does not change the result of addition and multiplication.

The associative property allows us to change the grouping of the addition operation, so we can rewrite the expression as follows; (12 + 3) + (negative 7), which simplifies to 15 + (negative 7) or 8. The commutative property on the hand, allows us to change the order of the addition operation. However, with regard to the question, it is not relevant because the expression involves addition and subtraction

If  all prime numbers are odd, then 2 is  odd.

2 is not odd.

Therefore, it is not the case that all prime numbers are odd.

Step-by-step explanation:

Considering part A

 The  first sentence is  

If all computer programs contain errors, then this program contains an error.

   The second sentence is

This program does not contain an error.

     The third  sentence is

Therefore, it is not the case that all computer programs contain errors.

Now we will use  a and  b  as the letter to denote the component sentences and   [tex]\neg a[/tex]  and [tex]\neg b[/tex] when the component sentences is not the case

So  a =  If all computer programs contain errors

and  

     b =  this program contains an error.

Generally then is represented as [tex]\to[/tex]

Hence the first sentence is denoted as  

         [tex]a \to b[/tex]

The  second sentence is represented as

            [tex]\neg b[/tex]

The  third sentence is represented as

           [tex]\neg a[/tex]

So part a can be represented as

      [tex]a \to b[/tex]

         [tex]\neg b[/tex]

         [tex]\neg a[/tex]

Considering part B

Here the objective is to fill in the blank spaces so that the logic of the sentence in part b is as that in part a

    Now comparing the second statement  a and  b

                "This program does not contain an error" = "2 is not odd" = [tex]\neg b[/tex]

Hence      "this program contains an error." =  "2 is  odd" =  b

     Now comparing the third  statement  a and  b

Therefore, it is not the case that all computer programs contain errors.  

                                                =

     Therefore, it is not the case that all prime numbers are odd  

                                                =

                                                [tex]\neg a[/tex]

Hence

If all computer programs contain errors, = if all prime numbers are odd.= a

Find k if 3k, k-2, and k + 7 are consecutive terms of an arithmetic sequence.

Answers

This is 1:25 (C)

Explanation:

The value of k is equal to -5.5

How to calculate the value of k in this arithmetic sequence?

In Mathematics and Geometry, the nth term of an arithmetic sequence can be calculated by using this equation:

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

Where:

d represents the common difference.a₁ represents the first term of an arithmetic sequence.n represents the total number of terms.

Based on the the common difference of an arithmetic sequence, we have:

k - 2 - 3k = k + 7 - (k - 2)

-2k - 2 = k + 7 - k + 2

-2k - 2 = 9

-2k = 11

k = -11/2

k = -5.5
