Answer:

  2/3

Step-by-step explanation:

Your model may show you that 1/4 = 2/8. Of course that will be 2 out of 3 of the 3/8 making up the other fraction of the same whole.

  1/4 = 2/3 of the fraction 3/8

Answer:

x = 27

Step-by-step explanation:

4(x−9)=4(9+1/3x).

Divide each side by 4

(x−9)=(9+1/3x)

Subtract 1/3 x from each side

x - 1/3x -9 = 9+1/3x -1/3x

2/3x -9 = 9

Add 9 to each side

2/3x -9+9 = 9+9

2/3x = 18

Multiply each side by 3/2

3/2 * 2/3x = 18*3/2

x = 27

Answer:

27

Step-by-step explanation:

4(x−9)=4(9+1/3x)

4x-36=36+(4/3)*x

(12/3)*x-36=36+(4/3)*x

(8/3)*x=72

8x=216

x=27

Answer:

in 6.36004793262 seconds

Step-by-step explanation:

h(t) = –16t^2 + v*t + h

0=-16t^2 + 70*t+ 202

t=(-70 ± sqrt((70^(2)-4*(-16)*202))/(2*(-16))

t=(-70 ± sqrt(4900+64*202))/-32

t=(-70 ± sqrt(4900+12928))/-32

t=(-70 ± sqrt(17828))/-32

t=(-70 ± sqrt(2*2*4457))/-32

t=(-70 ± 2 sqrt(4457))/-32

t=(-70 + 2 sqrt(4457))/-32

t=-1.98504793262

t=(-70 - 2 sqrt(4457))/-32

t=6.36004793262

since we need the time it will fall to the ground after it was thrown and time can't be negative, answer is

Answer:

the answer is A

Step-by-step explanation:

i went but the all the other answers in and it was left to  A

Option A is the correct answer.

What is the cost of one item if the cost of m items is x?

The cost of one item is obtained by dividing the total cost of m items by the number of items.

Given

The total amount spent by Sal > $24,

cost of 3 tennis balls = $2.

Cost of n tennis balls

Divide the cost of three tennis balls by 3 to get the cost of one tennis ball, which is $2/3.

Let the number of balls bought by Sal be n, and P be the cost of n tennis balls.

Total amount spent by him, P = cost of one ball × number of balls bought = ($2/3) × n = $(2/3)n.

Obtain the inequality

Since the total amount spent by him > $24, using the above value of P we obtain,

$(2/3)n > $24.

The inequality to be used to find n is (2/3)n > 24.

Answer: 465 π

Step-by-step explanation:

Hi, to answer this question we have to apply the next formula:  

Volume of a cylinder (V): π x (diameter /2) ² x height  

Replacing with the values given and solving for v (Volume)  

V = π x (6/2)²x 50

V = 450π

And then for the bottom part:

Volume of a cone = 1/3 x π x (diameter/2)^2 x height  

Replacing with the values given:  

V = 1/3 π (6/2) ^2 (5) = 15π

Finally we add the volumes:

450π+15π = 465 π

In conclusion, the volume of the solid is 465π m3.

Answer:  31 bacteria per square centimiter.

Step-by-step explanation:

The correct number of bacteria in the question is 2,450.

Hi, to answer this question we have to apply the next formula:

Area of a circle = π x (diameter/2) ^2

Replacing with the values given:

A = π x (10/2) ^2

A = π x (5) ^2

A = π x 25 = 78.54 cm2

Next, we have to divide the number of bacteria (2,450) by the area of the dish  

2450 / 78.54 = 31.19 = 31 bacteria per square centimiter.

Answer:

C

Step-by-step explanation:

C is the only viable answer, because it it the only one that decreases as x approaches infinity. Exponential decay decreases, hence the decay part.

The graph of the unknown function C represents exponential decay.

The correct option is C.

An exponential function's curve is created by a pattern of data called exponential decay, which exhibits higher decreases over time.

The exponential decay function:

Aₙ = A₀(1-r)ˣ, where y = Final amount, A₀ = Initial amount, r = Rate of decay in decimal form, x = Time.

Given:

Two graphs of the unknown functions are given.

And when the value of x approaches to positive infinity,

the value of y decrease exponentially.

And from the above definition,

the graph is C.

Therefore, the graph is C.

Answer:

D

Step-by-step explanation:

f(x) has a horizontal asymptote of -4 while g(x) has horizontal asymptote of zero, in both functions, y is closer to infinity as x is closer to negative infinity,

A and B are definitely incorrect

while x gets closer to infinity, in f(x) y gets closer to -4, while in g(x) y gets closer to 0, thus they have a different end behavior as x approaches infinity

So, C is wrong, since it says that they have the same end behavior as x approaches infinity

Thus, D is correct

Answer:

-200, -300, -450, -675

The geometric sequence which shows a pattern in which each term is 1.5 times the previous term is A = -200 , -300 , -450 , -675 ...

A geometric progression is a sequence in which each term is derived by multiplying or dividing the preceding term by a fixed number called the common ratio.

The nth term of a GP is aₙ = arⁿ⁻¹

The general form of a GP is a, ar, ar2, ar3 and so on

Sum of first n terms of a GP is Sₙ = a(rⁿ-1) / ( r - 1 )

Given data ,

Let the geometric progression be represented as A

Now , the value of A is

A = -200 , -300 , -450 , -675 ...

The common ratio of the GP = second term / first term

On simplifying , we get

r = -300 / -200

r = 3/2

r = 1.5

Therefore , each term is 1.5 times the previous term

Hence , the GP is solved

Answer:

Option B.

Step-by-step explanation:

The given exponential equation is

[tex]y=ab^x[/tex]  ...(1)

It is given that the graph of above equation passes through points (−3, 24) and (−2, 12).

The graph passes through the point (-3,24), so substitute  x=-3 and y=24 in equation (1).

[tex]24=ab^{-3}[/tex]   ...(2)

The graph passes through the point (-2,12), so substitute  x=-2 and y=12 in equation (1).

[tex]12=ab^{-2}[/tex]   ...(3)

Divide equation (3) by equation (2).

[tex]\dfrac{12}{24}=\dfrac{ab^{-2}}{ab^{-3}}[/tex]

[tex]0.5=b[/tex]

Substitute b=0.5 in equation (2).

[tex]24=a(0.5)^{-3}[/tex]

[tex]24=\dfrac{a}{(0.5)^{3}}[/tex]

[tex]24=\dfrac{a}{0.125}[/tex]

[tex]24\times 0.125=a[/tex]

[tex]3=a[/tex]

Substitute a=3 and b=0.5 in equation (1).

[tex]y=3(0.5)^x[/tex]

Therefore, the correct option is B.
