An air conditioner manufacturer recommends that its portable units provide between 4 and 6 BTUs of cooling per cubic foot to operate most efficiently. Which statement is true?

A 16,000-BTU air conditioner meets the manufacturer recommendation for a room measuring 20 feet by 20 feet with a standard 8-foot ceiling.
A 14,000-BTU air conditioner meets the manufacturer recommendation for a room measuring 10 feet by 20 feet with a standard 8-foot ceiling.
A 20,000-BTU air conditioner will be too large for a room measuring 20 feet by 40 feet with an 8-foot ceiling.
A 12,000-BTU air conditioner will be too small for a room that is 15 feet by 10 feet with a 10-foot ceiling.

so let's start ~

General term , [tex] A_{n} [/tex] = 3n + 10

let's consider certain values of n to get some information with us which will help us solve the problem further !

let's first consider , n = 1 ! then ,

[tex]3n + 10 = 3(1) + 10 \\ \dashrightarrow \: 13[/tex]

now , let's consider n = 2

[tex]3n + 10 = 3(2) + 10 = 6 + 10 \\ \dashrightarrow \: 16[/tex]

then , let's consider n = 3

[tex]3n + 10 = 3(3) + 10 = 9 + 10 \\ \dashrightarrow \: 19[/tex]

hence ,

now we've with us an AP which is as follows -

[tex]13 \: , \: 16 \: , \: 19 \: ......[/tex]

from this Arithmetic Progression ,

we can know that

a = first term = 13

d = common difference = 16 - 13 = 19 - 16 = 3

now ,

[tex]A _{n} = a + (n - 1)d \\ \implies \: A _{150} = 13 + (149)(3) \\ \implies \: A _{150} = 13 + 447 \\ \pink{\implies \: A _{150} = 460}[/tex]

Answer:    [tex]-\frac{240}{289}[/tex]

=========================================================

Explanation:

Use the pythagorean trig identity [tex]\sin^2(\theta)+\cos^2(\theta) = 1[/tex] and plug in the fact that [tex]\cos(\theta) = \frac{8}{17}\\\\[/tex]

Isolating sine leads to [tex]\sin(\theta) = -\frac{15}{17}\\\\[/tex]. I'm skipping the steps here, but let me know if you need to see them.

The result is negative because we're in quadrant 4, when y < 0 so it's when sine is negative.

Therefore,

[tex]\sin(2\theta) = 2\sin(\theta)\cos(\theta)\\\\\sin(2\theta) = 2*\left(-\frac{15}{17}\right)*\left(\frac{8}{17}\right)\\\\\sin(2\theta) = -\frac{240}{289}\\\\[/tex]

Answer:

39.5 in^3

Step-by-step explanation:

lol someone had the same question

The formula for a cone is (pi)(r^2)(h/3)

Since we have to use 3.14 for pi, we plug 3.14 in for pi:

(3.14)(r^2)(h/3)

The radius is 2 and the height is 8, so we plug in those numbers:

(3.14)(2^2)(8/3)

Simplify:

(3.14)(4)(2.666...)

Multiply:

(12.56)(2.666...) -> 39.49333...

Finally, we round 39.49333... to the tenths place:

39.5

Answer:

Answer:

1 hour and 15 minutes=75 mins.

Step-by-step explanation:

Answer:

4/x-8=8/2

4/x-8=4

4=4(x-8)

4=4x-32

4+32=4x

36=4x

dividing through by 4

x=9

converting to the nearest tenth will be 9.0

therefore x=9.0

Answer:

• No

• Yes

• Yes

• No

Step-by-step explanation:

To determine if the 4 given values of y are solutions to the inequality, start by solving the inequality. Solving an inequality is just like that of an equation, except that the direction of the sign changes when the inequality is divided by a negative number.

-2y +7≤ -5

Subtract 7 on both sides:

-2y≤ -5 -7

-2y≤ -12

Divide by -2 on both sides:

y≥ 6

This means that the solution can be 6 or greater than 6.

-10 and 3 are smaller than 6 and are not a solutions, while 7 and 6 satisfies the inequality and are therefore solutions.

_______

Alternatively, we can also substitute each value of y into the inequality and check if the value is less than or equal to -5.

Here's an example to check if -10 is a solution.

-2y +7≤ -5

When y= -10,

-2y +7

= -2(-10) +7

= 20 +7

= 27

Since 27 is greater than 5, it is not a solution to the inequality.

Total amount of tickets is 48

Step-by-step explanation:

Step 1:  Determine the amount of tickets they solid in all

We see that the movie theater has a ratio of 4 adult tickets for every children ticket which means that wen a child purchases a ticket there are 2 adult tickets that come along.

32 adult tickets / (2 adult tickets per child)

16 children tickets

Total tickets: 32 adult tickets + 16 children tickets = 48 tickets

Answer:  Total amount of tickets is 48

Answer:

False

According to the question, there are 37000 plants per hectare, the total corn plan required is 475,665.75 corn plants

The trapezium is a 2 -dimensional plane shape with the area calculated as shown below:

The formula for calculating the area of a trapezoid is expressed as:

Area = 0.5(a + b)h

Given the following parameters

Substitute the given parameters
Area = 1/2 (500 + 900) * 800
Area = 1/2 (1400) * 800
Area = 560000 square feet

Since 1 acre is equivalent to 43560 square feet, hence the total acre required is expressed as:

Total acre = 560000/43560
Total  acre = 12.856 acres

Also since there are 37000 plants per hectare, the total corn plan required is 475,665.75 corn plants

The number of people who voted for Cat-urday Night Fever as the best comedy film is given by the equation A = 182 people

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the number of people who voted for the comedy film be = A

Now , the equation will be

The total number of people = 280 people

The percentage of people who voted for the best comedy film = 65 %

So , number of people who voted for the comedy film A = percentage of people who voted for the best comedy film x total number of people

Substituting the values in the equation , we get

Number of people who voted for the comedy film A = ( 65 / 100 ) x 280

On simplifying the equation , we get

Number of people who voted for the comedy film A = 0.65 x 280

Number of people who voted for the comedy film A = 182 people

Therefore , the value of A is 182 people

Hence , the number of people is 182 people
