Answer:

ABCD is an isosceles trapezoid.

Step-by-step explanation:

The line AB will be horizontal (parallel to the x axis), because the y values are both 3. It is 9--2 = 11 units long.

CD is also parallel to the  x axis because the y values of C and D are both 6. Itis 5 - 2 = 3 units long.

The x values of the four points are all different so ABCD is a trapezoid.

Let's check the lengths of the line segments AC and BD:

AC = √((5--2)^2 + (6-3)^2 = √58.

BD =  √((9-2)^2 + (3-6)^2 = √58.

They are equal in length so:

ABCD is an isosceles trapezoid.

Answer:

B. The graph rises on the left side.

Step-by-step explanation:

The limit provided on the image is interpreted as; The limit of the function f(x) as x approaches negative infinity is infinity.

X is approaching negative infinity, this means that along the x-axis we are moving towards the left where the values of x become increasingly negative.

On the other hand, f(x) is approaching positive infinity, meaning that along the y-axis we are moving upwards where the values of y become increasingly positive.

This typically implies that as we move towards the left the graph of f(x) is moving upwards or basically the graph rises on the left side.

Answer:

b. the graph rises on the left side

The formula of the surface area of a cube is 6 x s²

→ s = 9

→ s² = 9²

→ s² = 81

→ 6 x 81 = 486

So, the surface area of the cube is 486 units².

Answer:

28

Step-by-step explanation:

Add 42, 85, and 69 together and you get 196 but you need to divide that by 7 and you get 28

Answer:

28

Step-by-step explanation:

We are given that

June has sports books=42

June has mystery books=85

June has nature books=69

Total number of shelves=7

We have to find the number of books are on each shelf.

Total number of books=42+85+69=196

To find the number of books on each shelf we will divide the total number of books by 7.

Number of books on each shelf=[tex]\frac{196}{7}[/tex]

Number of books on each shelf=28

Hence, number of books on each shelf=28

Answer:

if you take into consideration the run from yesterday,

Joe needs to run at least three more days

y > = 3

if you don't take into consideration the 3 mile run from yesterday,

The answer is

He needs to run 4 or more days toachieve his goal

y > = 4

Step-by-step explanation:

12 miles as a minimum

that means

let x be the total amount of miles ran

x > = 12

Let y be the number of days in which Joe runs

3*y > = 12

y > = 4

Joe needs to run for at least 3 more days to meet his goal of running at least 12 miles this week, considering that each run is 3 miles.

We can set up an inequality. Joe has already run 3 miles, so we need to find out how many more miles he needs to run. If Joe runs 3 miles each day, the inequality representing the situation is 3d + 3 \\geq 12, where d is the number of additional days Joe must run.

We can solve the inequality as follows:

This means Joe needs to run for at least 3 more days to meet his goal of 12 miles.

Answer:

25

Step-by-step explanation:

The radius of the circle, which is the perpendicular bisector of a 48-inch diameter kitchen breakfast bar template, is 30 inches. The correct option is C).

Let's break down the information given in the problem:

PQ is the perpendicular bisector of VW, and Q is the midpoint of VW. This means that PQ passes through the center of the circle.

The length of PQ (perpendicular bisector) is 18 inches.

VW is 48 inches in diameter, which means its radius is half of that, i.e., 48 inches / 2 = 24 inches.

Since PQ is the radius of the circle, and it is also the perpendicular bisector of VW, it divides VW into two equal parts, each measuring 24 inches (as VW has a diameter of 48 inches, and Q is the midpoint).

Now, we have a right-angled triangle, with PQ as the hypotenuse and two legs measuring 18 inches and 24 inches. We can use the Pythagorean theorem to find the length of PQ (the radius of the circle):

PQ² = 18² + 24²

PQ² = 324 + 576

PQ² = 900

PQ = √900

PQ = 30 inches

So, the radius of the circle is 30 inches.

The correct answer is option c) 30 inches.

The spanish song Decima has ten lines

Final answer:

A decima is a Spanish form of poetry that consists of ten lines per stanza, with a fixed rhyme pattern of ABBAACCDDC, representing a distinct structure from other forms like sonnets or haikus.

Explanation:

The decima is a form of Spanish poetry. Unlike a sonnet, which typically comprises fourteen lines and may follow various rhyme schemes such as the Shakespearian or Petrarchan forms, the decima is characterized by its ten-line stanzas. These stanzas adhere to a specific rhyme pattern and are traditionally written in eight-syllable lines. Each line in a decima ends with a rhyme following the pattern ABBAACCDDC. The form is quite popular in Spanish literature and folk music, and it is distinct in its total line count from other forms like the sonnet, sestina, and haiku.

Answer:

Step-by-step explanation:By AA similarity postulate

therefore the sides of the triangles are proportional, in particular

ADAB=ABAC ACBC=BCDC

By algebra we have the following equations

this is the same as

"Equals added to equals are equal" allows us to add the equations

AD⋅AC+AC⋅DC=AB2+BC2

By distributive property

AC(AD+DC)=AB2+BC2

but by construction AD+DC=AC.

Substituting we have

AC⋅AC=AB2+BC2

this is equivalent to

AB2+BC2=AC2

which is what we wanted to prove

The Pythagorean theorem uses similar triangles, This is equivalent to AB^2+BC^2=AC^2.

Answer:

c. first year: 240,000  

second year: 150,000

Step-by-step explanation:

We let the number of cars made in the second year be X. Consequently, the number of cars made in the first year would be X+90000 since we are told that 90,000 more cars were made in the first year than in the second year. Furthermore, we are also told that the total number of cars constructed in these two years is 390,000, implying that;

X+X+90000=390000

2X+90000=390000

2X=390000-90000

2X=300000

X=150000; number of cars made in second year

The number made in the first year is thus;

150000+90000 = 240000

Answer:

Option c is correct

So, the cars made in 1st year = x = 240,000

and the cars made in 2nd year = 150,000

Step-by-step explanation:

in this question we have to find the number of cars made in each year by The Flat Rock auto assembly plant.

Given:

the plant constructed a total of 390,000 cars and 90,000 more cars were made in the first year than in the second year

Let cars made in 1st year = x

and cars made in 2nd year = y

then the plant constructed a total of 390,000 will be :

x+ y = 390,000       (i)

and

90,000 more cars were made in the first year than in the second year can be written as:

x=90,000 +y         (ii)

Solving equation (i) and (ii) we can find the values of x and y

Putting value of x from eq (ii) into eq(i)

(90,000 + y) + y = 390,000

90,000 +y +y =390,000

2y = 390,000 - 90,000

2y= 300,000

y= 150,000

Putting value of y in equation (ii) we can find the value of x

x= 90,000 + y

x= 90,000 + 150,000

x= 240,000

So, the cars made in 1st year = x = 240,000

and the cars made in 2nd year = 150,000.

Let n represent the number. The stated relationship is ...

  5n -(-10) = -30

  5n = -40 . . . . . . . add -10

  n = -8

The number is -8.

Final answer:

To solve the equation given in the student's question, convert the operation of subtracting a negative number into addition, subtract 10 from both sides to isolate the term with x, and then divide by 5 to find that the number in question is -8.

Explanation:

The student's question is a linear algebra problem, which can be turned into a simple equation to find the unknown number.

According to the question, we multiply a number by five and then subtract a negative ten to get a difference of negative thirty.

Mathematically, this can be expressed as the equation 5x - (-10) = -30, and we can solve for x. First, we should simplify the equation by turning the subtraction of a negative number into an addition. This makes our equation 5x + 10 = -30.

To find the value of x, we then subtract 10 from both sides of the equation, which gives us 5x = -40.

Finally, we divide both sides by 5 to solve for x, leading us to an answer of x = -8.

where b is the base and h the perpendicular height

Using b = 20 and h = 12, then

A = 0.5 × 20 × 12 = 120 ft²
