The inequality that represents the possible area of the triangle is 2/7a < 10

The solution to the inequality is a < 35

From the question, we are to write and solve an inequality that represents the possible area, a, of the triangle

From the given information,

The base of the triangle is given by

b = 2/7a

Also, from the given information,

The base of the triangle is less than 10

That is,

b < 10

Then,

we can write that

2/7a < 10

This is the inequality that represents the possible area of the triangle

Now, solve the inequality

2/7a < 10

Multiply both sides of the equation by 7/2

7/2× 2/7a < 7/2× 10

a < 7 × 5

a < 35

Hence, the inequality that represents the possible area of the triangle is 2/7a < 10

The solution to the inequality is a < 35

Answer:

y=-5x-7

Step-by-step explanation:

For lines to be parallel with one another, that means they have to have the same slope. The slope of this equation is -5

From there we have to find the b (or the y-intercept) of the new equation. To do this we plug in the slope and the x and y from the given point (-2,3) into the equation y=mx+b and solve for b:

3=-5(-2)+b

3=10+b

-7=b

Finally, we make a new equation with the b (-7) and slope (-5):

y=-5x-7

DON'T READ IF YOU DON'T WANT TO/ALREADY KNOW HOW TO DO THIS FOR A LINE PERPENDICULAR TO THE GIVEN LINE:

To find a line perpendicular to (y=-5x+1), you do everything the same as before but instead of using -5 as the slope for your new equation (including the one you use for solving for the new b) you use it's negative reciprocal. That basically means you switch the numbers numerator and denominator and switch the sign. Remember, every whole number has a denominator of 1, so it'll look like this:

-5/1 turns into 1/5

Then you use 1/5 as the slope for the new equation by plugging in the x and y of the given point and solving for b like we did before. Finally you take the 1/5 as the slope and the b you solved for and put those into a equation like you did before and bam.

The piecewise function represented by the graph is:

A piecewise function is a function that has different definitions, depending on the input.

For x to the left of 0, inclusive, the function is constant at y = -3, hence the definition is:

f(x) = -3, x ≤ 0.

For x to the right of 0, with an open interval, the function is linear, with an intercept of 3(when x = 0, y = 3) and a slope of -3(the function fell from y = 3 to y = 0 when x moved from x = 0 to x = 1), hence:

f(x) = 3 - 3x, x > 0.

According to the question, let us consider the random variable for the discrete uniform distribution to be x.

What is the discrete uniform distribution?

Uniform distribution is another name for the rectangular distribution. And it is the family of the symmetric probability distribution. It has constant probability and the outcomes are equal in nature.

The standard formula for the mean and the variance of the distribution in terms of the lower bounds(L) and the upper bounds(U) is as follows:

Mean = (L+U)/2 ;

Variance = (L+U)/12

The value of the lower bound(L) is 1000 and the upper bound(U) is 1500.

The calculation is as follows:

Mean = (1000+1500)/2 = 1250

Variance =  (1000+1500)/12 = 208.3

Therefore, the values are: mean = 1250 and variance = 208.3

Step-by-step explanation:

50 books can be purchased with $ 350.

We have the data:

Books Cost (dollars)    Amount left (dollars)

            1                                    343

            2                                   336

            3                             336 - 7 = 329

            4                             329 - 7 = 322

            7                             322 - 21 = 301

           14                             301 - 49 = 252

Cost of 1 book = $ 7

Cost of b books = 7 × b = 7 b    

Amount of budget after b books = 350 - 7 b

We can buy = 350 / 7 = 50 books before spending the entire amount.

Therefore, we get that 50 books can be purchased with $ 350.

It will take 4 hours for both companies to equal the same price and it will cost $ 90 at that time.

There are two companies:

Company A-
It charges $ 50 to come and $ 10 per hour to work.

Let the number of hours worked be x

The equation will be:

Price of Company A = 50 + 10 x   …(1)

Company B-

It charges $ 30 to come and $ 15 per hour to work.

The equation will be:

Price of Company B = 30 + 15 x    …(2)

Now, for the same prices, we will equate (1) with (2):

50 + 10 x = 30 + 15 x

15 x - 10 x = 50 - 30

5 x = 20

x = 20 / 5

x = 4

At x = 4, price of the companies will be:

A = 50 + 10 (4) = 50 + 40

A = $ 90

B = 30 + 15(4)

B = 30 + 60

B = $ 90.

The smallest n such that 1 can be written as a sum of n

special numbers is 8.

A number is a mathematical concept that is used for counting, measuring, and labeling. The natural numbers 1, 2, 3, 4, and so forth are the original examples. Number terms in language can be used to represent numbers. More commonly, individual numbers can be represented using symbols known as numerals; for instance, the numeral "5" stands in for the number five. Basic numerals are frequently arranged in a numeral system, which is an ordered manner to represent any number, as only a very small number of symbols can be learned. The most widely used numeral system is the Hindu-Arabic numeral system, which enables the depiction of any number using a combination of 10 basic numerical symbols, or "digits."

Calculations:

Suppose 1 = x1 + x2 + · · · + xn where x1, x2, . . . , xn are special and

n ≤ 9. For k = 1, 2, 3, . . . , let ak be the number of elements of {x1, x2, . . . , xn}whose kth decimal digit is 7. Then

1 =7a1}/10 +7a2/10 +7a3/10 + ... ,

which yields

1/7 = 0.142857 =a1 /10 +a2/[tex]10^{2}[/tex] +a3/[tex]10^{3}[/tex] + ... ,

Hence a1 = 1, a2 = 4, a3 = 2, a4 = 8, etc. In particular, this implies that n ≥ 8. On

the other hand,

x1 = 0.700, x2 = x3 = 0.07, x4 = x5 = 0.077777, and x6 = x7 = x8 = 0.000777

are 8 special numbers whose sum is

The correct option is b. 16.67 acres would the lot next to it contain if it has a 900' frontage and is the same width as the first rectangular lot.

The quantity of space occupied by a flat surface with a specific shape is referred to as the area. It is calculated as a "number of" square units (square centimeters, square inches, square feet, etc.). The quantity of unit squares that can fit inside a rectangle called its area. Blackboards, painting canvases, laptop monitors, and other flat surfaces are a few instances of rectangular shapes.

Area of a Rectangle = (Length × Breadth) square units.

We know that the Area = Length × Width.

For first lot:

43,560 (sq. ft. in acre) × 25 acres = 1,089,000 sq. ft.

We know that 1,089,000 sq. ft. = Width × 1,350 (length). Therefore width =1,089,000 / 1,350 = 806.67.

From the problem the lots were of the same width.

In second lot: Area =806.67 (width) × 900( length)= 726,000 sq. ft. Therefore:

⇒726,000 (area) / 43,560 = 16.67 acres.

The measure of angle COD will be 85° and it will be an acute angle.

If an angles is less than 90°, it is known as an acute angle. If it is more than 90°, it will be an obtuse angle. And if it is equal to 90, then it is called a right angle.  

Here, we are given a a figure and we need to find the measure of ∠COD.

∠COD can be written as ∠AOB - ∠AOC - ∠DOB

Here, ∠AOB = 180° (straight line)

∠AOC = 30°

and ∠DOB = 65°

Thus, ∠COD = 180 - 30 - 65

Supplementary angles have a sum of 180°

Therefore, we can add the expressions for Angles A and B and set their sum equal to 180.

( 7x - 15 ) + ( 2x - 3 ) = 180

Now we can combine like terms and use inverse operations to find the value of x:

( 7x - 15 ) + ( 2x - 3 ) = 180

9x - 18 = 180

9x - 18 + 18 = 180 + 18

9x  = 198

9x/9 = 198/9

x = 22

Then Angle A will have a measure of 7x - 15 or 7• 22 -15 = 154 - 15 = 139°

m∠A = 139°

The measure of Angle b will be 2x - 3 = 2 • 22 - 3 = 44 - 3 = 41°
