Evaluate u + xy, for u = 18, x = 10 and y = 8

Answers

Answer 1

Salutations!

Evaluate u + xy, for u = 18, x = 10 and y = 8

This is just substituting values.

u = 18

x=10

y = 8

18 +10 * 8 = ?

Multiply 10 and 8

18 + 80 = 98.

Hope I helped (:

Have a great day!

Answer 2

U+xy

Where u=18,x=10,y=8

Sub in all these values

The argument is invalid because the premises are not true.

Answers

Answer:

The argument is valid by the law of syllogism.

Step-by-step explanation:

The law of syllogism is also called the law of transitivity. It is based on the transitive property, which states "if a = b and b = c, then a = c."

In our problem, our statement a would be "A quadrilateral has two pairs of parallel sides". Our statement b would be "It is a parallelogram." Our statement c would be "Its opposite angles are congruent."

That would make "if a = b"

"If a quadrilateral has two pairs of parallel sides it is a parallelogram."

Then "b = c" would be

"If a quadrilateral is a parallelogram, its opposite angles are congruent."

"a = c" would then be

"If a quadrilateral has two pairs of parallel sides its opposite angles are congruent."

This is the conclusion we were given, so this is the law of syllogism.

what is the solution of x^2+x-6≤0?

Answers

1) Factor the polynomial

x^2 + x - 6 = (x + 3) (x - 2)

So, can solve (x + 3)(x - 2) ≤ 0

The condition for the product of two factors be zero or negative is that the both are zero or have different signs (one positive and the other negative)

a) when x + 3 ≤ 0 and x - 2 ≥ 0

x + 3 ≤ 0 => x ≤ - 3

x - 2 ≥ 0 => x ≥ 2

Given that it is imposible that x be less or equal tha - 3 and greaer or equal than 2, this solution is empy.

b) when x + 3 ≥ 0 and x - 2 ≤ 0

x + 3 ≥ 0 => x ≥ - 3

x - 2 ≤ 0 => x ≤ 2

Solution: - 3 ≤ x ≤ 2 or [-3,2]

The iq scores of the five members of the duluth family are 100, 82, 104, 96, and 118. for this distribution of scores, the range is:

Answers

The range is the difference between the biggest and smallest number.

Let R = range

R = 118 - 82

R = 36

The range is 36.

Final answer:

The range of the IQ scores (100, 82, 104, 96, and 118) for the Duluth family is calculated by subtracting the lowest score from the highest (118 - 82), resulting in a range of 36 points.

Explanation:

The IQ scores of the five members of the Duluth family are 100, 82, 104, 96, and 118. To find the range of this distribution of scores, you first identify the highest and lowest scores in the set. The highest IQ score is 118, and the lowest is 82. The range is the difference between the highest and lowest scores, so:

Range = Highest score - Lowest score

Range = 118 - 82

Range = 36

Therefore, the range of the distribution of IQ scores for the Duluth family is 36 points.

A total of 231 tickets were sold for the school play. They were either adult tickets or student tickets. The number of student tickets sold was two times the number of adult tickets sold. How many adult tickets were sold?

Answers

well if there are 231 tickets, then divide 231 by three, that will equal 77, so if you see what i am doing,i am diving all tickets by 3 so that the students get 2/3 and the adults get the pther 1/3. so the answer is 77.

Final answer:

To determine the number of adult tickets sold for the school play, an equation was set up using algebra with x representing adult tickets, which turned out to be 77 after solving the equation x + 2x = 231.

Explanation:

The student has asked to find out how many adult tickets were sold when a total of 231 tickets were sold for a school play, with the number of student tickets being two times the number of adult tickets. To solve this, we can use algebraic methods and set up an equation.

Let x be the number of adult tickets sold, then the number of student tickets sold would be 2x. Given that the total number of tickets is 231, we can write the equation as:

x + 2x = 231

Simplifying, we get:

3x = 231

Dividing both sides by 3, we find that:

x = 77

Therefore, 77 adult tickets were sold.

To the nearest tenth, find the perimeter of ∆ABC with vertices A(2,4), B(-2,1) and C(2,1). Show your work.

Answers

First, we should calculate the lengths of the three sides (see the figure below).

The distance between two coordinates (x₁, y₁) and (x₂, y₂) is given by the formula
[tex]d= \sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}} [/tex]

Because the triangle is a right angle (indicated by the figure), we can determine the lengths of BC and AC easily.
The length of BC is the change in the x-coordinates, and AC is the change in the y-coordinates.
BC = 2 - (-2) = 4
AC = 4 - 1 = 3

To find AB, use the distance formula (the same as the Pythagorean theorem).
AB = √[(2-(2)) ²+ (4-1)² ] = √(4²+3²) = √25 = 5

The area of the triangle is (1/2)*BC*AC = (1/2)*4*3 = 6

The line from the point to its reflection should be perpendicular.If we imagine a line from (5,7) to (2,2), it would have a slope of (2-7)/(2-5) = 5/3.

For that line to be perpendicular to y=-2/5x+6, their slopes should be each other's negative reciprocals.

-2/5 negative reciprocal is 5/2, which is not equal to our calculated 5/3, so (2,2) cannot be the reflected point. Evan was wrong.

A. about 0.52 of the field
B. about 0.64 of the field
C. about 0.71 of the field
D. about 0.87 of the field

Answers

Roni would mow about 0.71 of the field.

Answer: C. about 0.71 of the field

Step-by-step explanation:

Since, Roni can mow the field in 30 minutes.

Thus, the work done by Roni in one day = 1/30

And, Allie can mow the field in 75 minutes.

Thus, the work done by Allie in one day = 1/75

⇒ The total work done by Roni and Allie in one day when they worked simultaneously,

= [tex]\frac{1}{30} + \frac{1}{75}[/tex]

= [tex]\frac{5}{150} + \frac{2}{150}[/tex]

= [tex]\frac{7}{150}[/tex]

[tex]\implies \text{The part of work done by Roni} = \frac{\text{the work done by her in one day}}{\text{Total work they done in one day}}[/tex]

[tex]= \frac{1/30}{7/150}[/tex]

[tex]= \frac{5}{7}=0.714285714\approx 0.71[/tex]

Sue: 18 - x - 5 = 13 - x

Tony: 18 + x - (1/2)x = (3/2)x + 18

Here's a breakdown of the calculations:

Sue's sweets:

Sue starts with 18 sweets.

She gives Tony x sweets.

She then eats 5 of her sweets.

Therefore, Sue now has 18 - x - 5 sweets, which can be simplified to 13 - x.

Tony's sweets:

Tony starts with 18 sweets.

Sue gives him x sweets.

He then eats half of his sweets.

Since Tony eats half of his sweets, he is left with (1/2) of his sweets. Therefore, Tony now has 18 + x - (1/2)x sweets, which can be simplified to (3/2)x + 18.

The equation of a parabola is given.y=1/8x^2+4x+20 What are the coordinates of the focus of the parabola?

Answers

he equation of a parabola is x = -4(y-1)^2. What is the equation of the directrix?
You may write the equation as
(y-1)^2 = (1) (x+4)
(y-k)^2 = 4p(x-h), where (h,k) is the vertex
4p=1
p=1/4
k=1
h=-4

The directrix is a vertical line x= h-p
x = -4-1/4
x=-17/4

-------------------------------
What is the focal length of the parabola with equation y - 4 = 1/8x^2
(x-0)^2 = 8(y-4)
The vertex is (0,4)
4p=8
p=2 (focal length) -- distance between vertex and the focus
-------------------------------
(y-0)^2 = (4/3) (x-7)
vertex = (7,0)
4p=4/3
p=1/3
focus : (h+p,k)
(7+1/3, 0)

Convert it to vertex form we get

y = 1/8(x + 16)^2 - 12

so the vertex is at (-16,-12) and the x coordinate of the focus will be -16)

The focus will be at (-16, k + p) Here k = -12 from the vertex equation and p = 1 / 4a where a = 1/8 so p = 1 / 1/2 = 2 So k + p = -12 + 2 = -10

So the coordinates of the focus are (-16, -10) answer

The answer is 5. The question wants you to compose the functions to get g(x) composed of f(x). Typically, when composing functions your substitute the second function into the first function in place of x. However, the function g(x) is constant at 5 since it has no x values. g(x)=5 means that g(x) is 5 at all values of x. Thus, in this case, it doesn't matter that we are doing a composition because the top-level function is g(x) and g(x) is 5 no matter what.

133° = mes ∠ AKD + 87°

Final answer:

To find m∠AKD, subtract the measure of ∠AKG from 180 degrees.

Explanation:

To find the measure of ∠AKD, we need to use the fact that the sum of the measures of angles in a triangle is 180 degrees. Since we know that ∠AKG is 133 degrees, we can subtract this from 180 to find the remaining angle.
