distance between A (2, -1) and (2,a) is 4 units. Find the value of a where a is positive.

Answer:

y = 40             x = 80

Step-by-step explanation:

520 = 3.25x + 6.5y     and   x+y=120

x+y=120

x = 120-y

520 = 3.25(120-y)+6.5y

520 = 390-3.25y+6.5y

520 = 390+3.25y

130=3.25y

40 = y

x = 120-y

x = 120-(40)

x = 80

The number of integers that satisfies the inequalities, -5 ≥ -7•x and -15 ≥ 5•x is zero or non

The given inequalities are;

-5 ≥ -7•x and -15 ≥ 5•x

Simplifying the inequalities gives;

-5 ≥ -7•x

Dividing both sides by -7 gives;

-5/-7 ≤ -7•x/-7 = x

Therefore;

5/7 ≤ x

Which gives;

The second inequality is simplified as follows;

-15 ≥ 5•x

-15/5 ≥ 5•x/5

-3 ≥ x

Which gives;

x ≤ -3

Therefore;

-3 ≥ x and x ≥ 5/7

5/7 ≤ x ≤ -3

However, 5/7 > -3

The number of integers that satisfies the inequality, 5/7 ≤ x ≤ -3, is zero (no integer satisfies the inequality).

Therefore;

Non of the integers satisfies both -5 ≥ -7•x and -15 ≥ 5•x

Answer:

Let's create this right triangle.  We will call it triangle ABC with angle B as the right angle, angle A being the larger of the angles A and C.  If the ratio is 5:4, then it is A:C.  5+4 = 9.  The measure of the right angle, angle ABC = 90, and 90 divided by 9 is 10.  So angle A is 5 * 10 which is 50 degrees, and angle C is 4 * 10 which is 40 degrees.  The smallest angle, angle C, is 40 degrees.

Answer:

A. How to determine the constant

  Let the total cost be C

   Let the number of acres be A

From the question given above,

C ∝ A

C = KA

K = C / A

   Total cost (C) = $ 551520

   Number of acres (A) = 20 acres

   Conctant (K) =?

K = C / A

K = 551520 / 20

K =  27576 dollar/acre

B. How to determine the number of acres

   Total cost (C) = $ 441216

   Constant (K) =  27576 dollar/acre

   Number of acres (A) =?

C = KA

Divide both side by K

A = C / K

A = 441216 / 27576

A = 16 acres

Answer: x=5.75

Step-by-step explanation:

4x+5=28

subtract 5 from both sides

4x=23

divide both sides by 4

x=5.75

In the given figure it looks like rhombus , so we know that all sides of rhombus are equal

Thus

FG=EG

28=4x+5

28-5=4x

23=4x

x=23/4

Considering the definition of an inequality, you get:

a. the numbers of glass bottles your class needs to collect if no plastic bottles are collected is 2000.

b. the numbers of plastic bottles your class needs to collect if no glass bottles are collected is 1000.

c. the inequality that represents how many of each type of bottle your class can collect to reach the goal is 0.05×g + 0.10s≥100.

An inequality is the existing inequality between two algebraic expressions, connected through the signs:

An inequality contains one or more unknown values ​​called unknowns, in addition to certain known data.

Solving an inequality consists of finding all the values ​​of the unknown for which the inequality relation holds.

In this case, you know that:

Being:

a. the numbers of glass bottles your class needs to collect if no plastic bottles are collected is calculated as:

0.05×g≥100

Solving:

g≥100÷ 0.05

g≥2000

b. the numbers of plastic bottles your class needs to collect if no glass bottles are collected is calculated as:

0.10×s≥100

Solving:

s≥100÷ 0.10

s≥1000

c. the inequality that represents how many of each type of bottle your class can collect to reach the goal is:

0.05×g + 0.10s≥100

In summary, you get:

a. the numbers of glass bottles your class needs to collect if no plastic bottles are collected is 2000.

b. the numbers of plastic bottles your class needs to collect if no glass bottles are collected is 1000.

c. the inequality that represents how many of each type of bottle your class can collect to reach the goal is 0.05×g + 0.10s≥100.

Step-by-step explanation:

p^2 - 11p + 30

find what two numbers added together is -11 but multiplies together is 30, its' -5 and -6 so:

(p - 5)(p - 6)

Answer:

(p - 5)(p - 6)

Step-by-step explanation:

Given

p² - 11p + 30

Consider the factors of the constant term (+ 30) which sum to give the coefficient of the x- term (- 11)

The factors are - 5 and - 6, since

- 5 × - 6 = + 30 and - 5 - 6 = - 11 , thus

p² - 11p + 30 = (p - 5)(p - 6) ← in factored form

Answer:

Step-by-step explanation:

The first two problems can be solved in your head by working backward from the end result.

__

1. After 3/2 is added, the result is 4. Then we must be adding 3/2 to 4 -3/2 = 5/2. We notice that 5/2 already has the numerator 3 more than the denominator, so the fraction of interest is 5/2.

__

2. If 3/8 is added to a number giving a result of 1, the number must be 1 -3/8 = 5/8. That is 5 times 1/8. The number of interest is the reciprocal of 1/8, so is 8.

__

3. Let x represent the speed of the faster car. Then x-3 is the speed of the slower car, and the two times are ...

  time = distance/speed

  390/x = 372/(x-3)

  390(x -3) = 372x . . . cross multiply

  18x = 1170 . . . . . . . add 1170-372x

  x =  65 . . . . . . . . . . divide by 18

The speeds of the cars are 65 mph and 62 mph.

An equation of the parabola with focus (2, 2) and vertex (2, 6) is  mathematically given as

(x-2)^2=-16(y-6)

This is further explained below.

Generally, A planar curve that is mirror-symmetrical and has an approximation of the form of the letter U is called a parabola.

It agrees with a number of mathematical descriptions that, at first glance, seem to be very distinct from one another, but which can be shown to describe the same curves. A point and a line are two components that may be used to describe a parabola.

In conclusion, It can be shown theoretically that the equation of the parabola with focus (2, 2) and vertex (2, 6) is as follows:

(x-2)^2=-16(y-6)
