Answer:

x = -2.2

Step-by-step explanation:

-2x - 14 = 7x + 6

-2x - 7x = 6 + 14

-9x = 20

x = 20/-9

x = -2.2222

x = -2.2   (nearest tenth)

Answer:

7

Step-by-step explanation:

A line segment partitioned by a ratio of 3:4 can be thought of as having 7 congruent sections

According to the ratio in which it is partitioned, the line segment can be thought as having 7 congruent sections.

If it can be divided into a ratio of a:b, it can be partitioned into a + b congruent segments.

In this problem, it has a ratio of 3:4, hence, the line segment can be thought as having 7 congruent sections.

Answer:

Height of the triangle is 6 feet and base of the triangle is 4 feet.

Step-by-step explanation:

Area of a triangle is given by the formula,

Area = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]

Let the height of triangle = h feet

Since, base of the triangle is 2 feet less than its height then base of the triangle = (h - 2) feet

Area = [tex]\frac{1}{2}h(h-2)[/tex]

[tex]12=\frac{1}{2}h(h-2)[/tex]

h² - 2h - 24 = 0

h² - 6h + 4h - 24 = 0

h(h - 6) + 4(h - 6) = 0

(h + 4)(h - 6) = 0

h = -4, 6 feet

Since height of the triangle can not be negative, therefore, height of the triangle = 6 feet.

And base of the triangle = (h - 2) = 6 - 2

                                         = 4 feet

Height of the triangle is 6 feet and base of the triangle is 4 feet.

[tex]k=5.2[/tex]

Step-by-step explanation:

So we have the equation:

[tex]9.3=k+4.1[/tex]

To solve for k, subtract 4.1 from both sides:

[tex](9.3)-4.1=(k+4.1)-4.1[/tex]

The right cancels. Simplify the left:

[tex]5.2=k\\k=5.2[/tex]

Thus, the value of k is 5.2

Answer:

[tex]\huge \boxed{k=5.2}[/tex]

Step-by-step explanation:

[tex]9.3=k+4.1[/tex]

Subtract 4.1 from both sides.

Answer:

3

Step-by-step explanation:

3 because 3 is a good number....lol

Answer:

I will answer in English:

We first have a rational number, the quotient between 2 positive integer numbers is 0.57....

And we want to find which number we should add in order to get 1.

Then we have:

A/B = 0.5757...

So if we have:

x = 0.5757....

we have two periodic decimals, then we multiply by 100 (the number of zeros is equal to the number of periodic decimals)

100*x = 57.575757

Now we subtract the original number:

100*x - x = 99*x = 57.575757... - 0.5757 = 57.

Then we have:

99*0.5757... = 57

0.575757... = 57/99

Now that we know the original fraction, if we want to find a fraction such that:

0.57... + a/b = 1

57/99 + a/b = 1

we should use the same denominator in both fractions:

b = 99

57/99 + a/99 = 1

57 + a = 99

a = 99 - 57 = 42

Then the fraction is 42/99

Answer:

[tex]n = 500e^{-4.1589x}[/tex]

Step-by-step explanation:

Using the exponential growth equation [tex]N(t) = N_0e^{-kt}[/tex] where;

N₀ is the initial population of the bacteria

N(t) is the population of the bacteria during time t

If a biologist puts an initial population of 500 bacteria into a growth plate, this means that N₀ = 500 at t = 0

[tex]N(t) = N_0e^{-kt}\\N(t) = 500e^{-k(0)}\\N(t) = 500e^0\\N(t) = 500[/tex]

If the population is expected to double every 4 hours, this means when t = 4, N₀  = 2(500) = 1000

[tex]N(t) = N_0e^{-kt}\\500 = 1000e^{-4k}\\\frac{500}{1000} = e^{-4k}\\0.5 = e^{-4k}\\ln(0.5) = lne^{-4k}\\ln(0.5) = -4k\\k = \frac{ln0.5}{-4} \\k = 0.1733[/tex]

The equation that will give the expected number of bacteria, n, after x days, can be gotten by substituting N(t) = n and t = x days = 24x hours

[tex]N(t) = N_0e^{-kt}\\n = N_0e^{-0.1733(24x)}\\n = 500e^{-4.1589x}[/tex]

Hence the equation that will give the expected number of bacteria, n, after x days is [tex]n = 500e^{-4.1589x}[/tex]

Answer:

-15 meters

Step-by-step explanation:

If it goes up 50 meters from the ground, it will be 0+50 which is 50.

Then it says it drops 65 meters into an underground tunnel.  So at 50 meters, it dropped 65 meters.  That means you subtract this: 50-65, which equals -15 meters because 50 goes into 65 but there is still 15 left, so the 15 is negative.

The ground level is at 0.  And we just found out that the tunnel is at -15 meters.  To find out how many meters the tunnel is below the ground, just do 0-15, which is still -15 meters.   :)

Answer:

C. 14%

Step-by-step explanation:

We know that Dallas's wage increased from $9 to $10.25.

Let's say the percent increase is x. Then we write the expression:

9 + x * 9 = 10.25

Divide by 9 from both sides:

1 + x = 10.25 / 9 ≈ 1.14

Subtract 1 from both sides:

x = 1.14 - 1 = 0.14

Since x is a percent, that means x = k/100, where k is an integer. So we have:

x = k/100 = 0.14

Multiply both sides by 100:

k = 0.14 * 100 = 14%

The answer is thus C.

Answer:

width = 6 ft

Step-by-step explanation:

let  A = 24 3/5 = (24*5 +3)/5 = 123/5 ft^2 the area

l = 4 1/10 = (4*10 + 1)/10 = 41/10 ft the length

w = the width, w>0

since the area = length*width we have:

l*w = A

(41/10)*w = 123/5

by solving we find:

w = 6 ft

Answer:

(3,0)

Step-by-step explanation:

Co-ordinates of J =(4,3)

Co-ordinates of K = (2,-3)

Midpoint formula :

 = [tex]\frac{x_{1}+x_{2} }{2} , \frac{y_{1} +y_{2} }{2} \\ \frac{4+2}{2} ,\frac{3+(-3)}{2}\\\frac{6}{2},\frac{3-3}{2}\\3, 0[/tex]

Coordinates of the midpoint M (3,0)

The coordinates of the midpoint M is (3,0) and the distance between J(4,3) and K(2,-3) is 6.32 units.

The distance between two points of the xy-plane can be found using the distance formula. The distance formula is:

√[(x₂ - x₁)² + (y₂ - y₁)²].

Now given coordinates of two points are,

J(4,3) and K(2,-3)

Therefore we have,

x₁ = 4

y₁ = 3

x₂ = 2

y₂ = -3

To find the midpoint between J and K we have,

{[(x₁+x₂ )/2] , [(y₁+y₂ )/2]}

Put the values, we get

{[(4+2)/2] , [(3+(-3)/2]}

solving them,

{(6/2) ,(0/2)}

or,

(3,0)

which is the required midpoint M.

Now distance between J(4,3) and K(2,-3) = √[(x₂ - x₁)² + (y₂ - y₁)²]

= √[(2 - 4)² + (-3 - 3)²]

= √[(- 2)² + (-6)²]

= √4 +36

= √40

= 6.32 units

Thus, the coordinates of the midpoint M is (3,0) and the distance between J(4,3) and K(2,-3) is 6.32 units.

Answer:

2(x+4)

Step-by-step explanation:

Tom ate four more pieces of fruit than Janet. Sylvia ate twice as many pieces of fruit as Tom. If x represents the number of pieces of fruit that Janet ate, write an expression to represent the amount of fruit that Sylvia ate.

Janet: (X)

Tom: X+4

Sylvia: 2(X+4)

I started by making listing out who did what. Janet is stated as clearly X, so that's all we need for her.

The question says Tom ate four more pieces of fruit than Janet. This is simple addition since you're adding four to Janet's amount of fruit. Therefore this makes Tom's equation X+4.

Then Sylvia eats TWICE the amount as Tom. In simpler terms, she's doubling the amount of food Tom eats. Doubling something is simply multiplying it by two. Therefore, we take Tom's amount eaten, which we made into an equation in the paragraph before this one, and multiply it by two.

Placing parenthesis around Tom's equation means that that part is solved before its multiplied. We do this because we need to acknowledge that X+4 is its own equation that needs to be clarified/solved before being doubled. So, the answer is 2(X+4)
