it due in a lil bit

Answers

The answer is D. You’re welcome.

Step by step: it’s asking you to find side BD, which is the adjacent to angle B.
And you know the opposite of angle B is AC or 3 inches.

This operation calls for TOA. T stands for Tan, OA stands for Opposite over Adjacent.
So we would do:
tan 60 = 3/x
And then next would be
x = 3/tan 60
Then, you probably have a calculator, so on a calculator do 3 divided by 60 and then press tan and press equal. You will get 1.73 which rounds to 1.7

15 dance tickets were sold in one half hour. If this rate continues, how many hours would you expect it to take to sell 270 tickets?

Answers

First, you would divided 270 by 15

270 ÷ 15 = 18

Then, you would divide 18 by 2 because it only takes half an hour to sell 15.

18÷2 = 9

Therefore, it would take 9 hours!

-----

Another Way!

First, multiply 15 by 2 because it only takes half an hour to sell 15.

15×2 = 30

Then, divide 270 by 30!

270÷30 = 9

Therefore, it would take 9 hours!

A young sumo wrestler decided to go on a special diet to gain weight rapidly. He gained weight at a constant rate.

The table compares the wrestler's weight (in kilograms) and the time since he started his diet (in months).

How fast did the wrestler gain weight?

___ kilograms per month​

Answers

Finding the rate of the weight gain, we divide the total weight gained with the total number of months that took to gain that weight.

Total time (months) = 0.5 + 2 + 3.5 = 6 months

Total weight (kg) = 80.6 + 88.4 + 96.2 = 265.2 kilograms

Rate = Kg ÷ Months

Rate = 265.2 ÷ 6 = 44.2

44.2 kilograms per month​

Please help!!! The function d= 16t2 models the distance d, in feet, that an object falls in t seconds.
Find the inverse function and use the inverse function to estimate the time it takes an
object to fall 100 feet.
The inverse function is t = d/4
The time the object falls is 5 seconds.
The inverse function is t = d/16
The time the object falls is 0.625 seconds.
The inverse function is t = d/4
The time the object falls is 2.5 seconds.
The inverse function is t = d/16
The time the object falls is 6.67 seconds.

Lena drove 355 miles using 17 gallons of gas. At this rate, how many gallons of gas would she need to drive 284 miles.​

Answers

Answer:

13.6 gallons

Step-by-step explanation:

Miles Driven = Gallons Burnt * Miles Per Gallon

 

So if yo drive 20.88 miles on one gallon how many gallons does it take to drive 284 miles.  This is 284/20.88 = 13.6 gallons

 

Whilst the numerical answer is correct the previous answer, it does not maintain the validity of the units - in which things are measured.  You will see this is very important in science

 

What can we learn from this.  As an intermediate step we have learnt that the car does 20.88 mpg, lets call it 21.  So a car that has a sticker at the show room with an MPG of more than 21 will consume less gas and one that has a smaller mpg will consume more.

the sum of two and a number is less than five

Answers

Answer:

Please check the explanation.

Step-by-step explanation:

Given the English statement

''The sum of two and number is less than five''.

Let us breakdown the statement.

Let 'n' be the number. The sum of two and number = 2 + n

We know that the less than symbol is denoted by '<' which is used for comparison.

Thus, the statement 'The sum of two and a number is less than five' is algebraically represented as:

2 + n < 5

Let us solve the algebraic expression.

[tex]2+n<5[/tex]

Subtract 2 from both sides

[tex]2+n-2<5-2[/tex]

Simplify

[tex]n<3[/tex]

Thus, the solution is:

[tex]2+n<5\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:n<3\:\\ \:\mathrm{Interval\:Notation:}&\:\left(-\infty \:,\:3\right)\end{bmatrix}[/tex]

Answers

The domain of the function f(x) = 2x² + 2x + 4  is (-∞, ∞).

What is Quadratic equation?

The polynomial equation whose highest degree is two is called a quadratic equation or sometimes just quadratics. It is expressed in the form of:

ax² + bx + c = 0

where x is the unknown variable and a, b and c are the constant terms.

You have the quadratic function

f(x) = 2x² + 2x + 4 ,

and remember that all quadratic functions are parabolas opening at point called the vertex.

Since you can plug any real number in our parabola here, its domain is all the real numbers, and this is true for all the quadratic functions of the form ax² + bx + c = 0.

Thus, in interval notation the domain of the function  is (-∞, ∞).
