A field is a rectangle with a perimeter of 1160 feet. The length is 400 feet more than the width. Find the width and length of the rectangular field.

Answer:

B.

Step-by-step explanation:

$2.25 is the cost of each video that is rented, so $2.25 times v (or 2.25v) represents the cost of 'v' videos.

$20 is the constant, as it costs $20 to join the club. Since this doesn't change, it is the constant.

So, we would have the equation:

f(v) = 2.25v + 20

f(v) is the total cost.

B is your answer because it is the only one with the correct equation.

Hope this helps!

Answer:

1536 boys.

Step-by-step explanation:

Quite simple! 51.2% is 0.512, which we can use to calculate the number.

[tex]3000 * 0.512 = 1536[/tex] boys.

Alternative notation: 3000 * 51.2% = 1536

Answer:

I think the answer is 75.

Step-by-step explanation:

because 35 + 70 is equal to 105. So now we will just subtract 105 by 180. which will give us 75.

Answer:

Radius, r = 2.50 inches

Step-by-step explanation:

Given the following data;

Slant height of cone = 6 inches

Lateral surface area (LSA) of cone = 47.1 sq inches

To find the radius of the cone;

Mathematically, the lateral surface area of a cone is given by the formula;

LSA = πrl

47.1 = 3.142 * r * 6

47.1 = 18.852r

Radius, r = 47.1/18.852

Radius, r = 2.50 inches

Answer:

Number 2 is 3:4.

Number 1 is d.

Step-by-step explanation:

Boxers and collies added together gives you 12:16. Divide them both by 4 and you get 3:4.

Answer:

i)  Speed and travel time

ii) Coffee and car

Step-by-step explanation:

i) Example of a pair of variable that have a negative Linear correlation

A negative correlated pair of variables simply means that the variables are inversely proportional to each other .and an example of such pair of variables is

Speed and Travel Time

Increase in speed causes a decrease in travel time. ( because the faster a car travels the shorter the travel time spent by the car while the slower a car travels the longer the travel time spent by the car )

ii) Example of a pair of variable with no linear correlation ( almost zero )

A close to zero linear correlation shows that there i no actual relationship between the variables.

Coffee and car

Increase or decrease in the cost of coffee will have no significant effect ( either negative or positive ) on the price of cars in the open market.

A = p(1+r)^t

Answer:

Simple interest:  Principal = $2000

Annual compound interest:  Principal = $1380.59

Step-by-step explanation:

As the question does not stipulate which type of interest was applied, please find below calculations for both simple interest and annual compound interest.

Simple Interest Formula

I = Prt

where:

Given:

Substitute the given values into the formula and solve for P:

[tex]\implies \sf 1600=P(0.08)(10)[/tex]

[tex]\implies \sf 1600=0.8P[/tex]

[tex]\implies \sf P=\dfrac{1600}{0.8}[/tex]

[tex]\implies \sf P=2000[/tex]

Therefore, the initial deposit (principal) was $2000.

.....................................................................................................

Annual Compound Interest Formula

[tex]\large \text{$ \sf I=P\left[\left(1+r\right)^{t} -1\right]$}[/tex]

where:

Given:

Substitute the given values into the formula and solve for P:

[tex]\implies \sf 1600=P\left[\left(1+0.08)^{10}-1\right][/tex]

[tex]\implies \sf 1600=P\left[\left(1.08)^{10}-1\right][/tex]

[tex]\implies \sf 1600=P\left[2.15892...-1\right][/tex]

[tex]\implies \sf 1600=P\left[1.15892...\right][/tex]

[tex]\implies \sf P=\dfrac{1600}{1.15892...}[/tex]

[tex]\implies \sf P=1380.5897...[/tex]

Therefore, the initial deposit (principal) was $1380.59 (nearest cent).

Answer: Crissy is correct

Step-by-step explanation:

Given

The volume of the rectangular prism is [tex]360\ units^3[/tex]

The height of the prism is [tex]h=10\ units[/tex]

Suppose A is the area of the base

So, the volume is given by

[tex]\Rightarrow V=A\times h[/tex]

Insert the values

[tex]\Rightarrow 360=A\times 10\\\Rightarrow A=36\ \text{or}\ 6\times 6\ units^2[/tex]

As 36 is the perfect square of 6, therefore, the base is a square with the dimension of [tex]6\times 6\ units^2[/tex]

Crissy's claim is correct.

The length of the arc is 6.28 inches

Step-by-step explanation:

Given

[tex]\theta = 60[/tex]

Required

Length of the arc

This is calculated as:

[tex]L = \frac{\theta}{360} * 2\pi r[/tex]

So, we have:

[tex]L = \frac{60}{360} * 2 * \frac{22}{7} * 6[/tex]

Answer:

Option (D)

Step-by-step explanation:

Given equation is,

[tex]8e^{2x+1}=4[/tex]

Taking natural log on both the sides of the equation,

[tex]\text{ln}(8e^{2x+1})=\text{ln}(4)[/tex]

[tex]\text{ln}(2^3)+\text{ln}(e^{2x+1})=\text{ln}(2^2)[/tex]

3ln(2) + (2x + 1)[ln(e)] = 2ln(2)

2n(2) - 3ln(2) = (2x + 1)

2x = -ln(2) - 1

[tex]2x=\text{ln}(\frac{1}{2})-1[/tex]  [Since, -ln(2) = ln(1) - ln(2) = [tex]\text{ln}(\frac{1}{2})[/tex]]

[tex]2x=\text{ln(0.5)}-1[/tex]

[tex]x=\frac{\text{ln(0.5)-1}}{2}[/tex]

Therefore, Option (D) will be the correct option.
