Can I have Brainliest?

Answer:

$225

Step-by-step explanation:

25% of 300 is also 1/4 of 300 which is 75

you take the discounted price away from the original price

300-75=225

Given:

The function is

[tex]y=3x[/tex]

Domain of the function is {9, 15, 18, 21, 27}.

To find:

The range of the function.

Solution:

We have,

[tex]y=3x[/tex]

Domain is set of input (x-values) and range is the set of output (y-values).

Domain =  {9, 15, 18, 21, 27}

For x=9,

[tex]y=3(9)=27[/tex]

For x=15,

[tex]y=3(15)=45[/tex]

For x=18,

[tex]y=3(18)=54[/tex]

For x=21,

[tex]y=3(21)=63[/tex]

For x=27,

[tex]y=3(27)=81[/tex]

So, the y-values are 27, 45, 54, 63, 81.

Therefore, the range of the function is {27, 45, 54, 63, 81}.

Answer:

1,047

Step-by-step explanation:

n = distance from Boston to St. Louis

2410 is 230% of n

2410 = 2.3n

2410/2.3 = n

1,047 miles = n

Answer:

4.66

Step-by-step explanation:

Cause 4 would be 4.0 and then you take 100 and divide by the denominator and you get .33 for every 1/3. Since you have 2/3 it would be .66, then your answer would be 4.66

Step-by-step explanation:

From the picture attached,

Given:

SE ≅ EP

∠ESA ≅ ∠ EPN

To Prove:

ΔSEA ≅ ΔPEN

Solution:

             Statements                        Reasons

1). SE ≅ EP                                1). Given

2). ∠ESA ≅ ∠ EPN                   2). Given

3). ∠SEA ≅ ∠NEP                    3). Vertical angles theorem

4). ΔSEA ≅ ΔPEN                    4). By ASA postulate

Therefore, Option C is the correct option.

Step-by-step explanation:

Answer:

180 X 365 = 65700 litres

65700/1000 = 65.7 cubic metres

65.7 X 91.22 = 5993.154

5993.154 / 100 = 59.93154

59.93 + 28.20 = 88.13

Answer:

C. 5.8

Step-by-step explanation:

We use the Pythagoras theorem here. which is a²+b²=c².

a and b are the replacements for the 5miles and  3miles here.

They are a and b because a  and b are always on the right angle side.

The longest side of this triangle is called a hypotenuse which is the c in this case.

the other sides (a and b) are called the adjacent and the opposite.

it doesn't matter if you use adjacent or opposite for a and b in this case.

the only important thing is the hypotenuse here.

So it's a²+b²=c², which is 5²+3²=c².

5² is 25 and 3² is 9, so we add them and we get 34.

so c²=34, we don't want the square on c  so we send it to 34 which becomes √34.

√34 gives us 5.8 miles which is up to just only one decimal place.

You might need to use calculators for square roots because they take long to calculate.

Answer:

The slope between (8, 10) and (14, -5) will be:

Step-by-step explanation:

Given the points

Finding the slope between (8, 10) and (14, -5)

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(8,\:10\right),\:\left(x_2,\:y_2\right)=\left(14,\:-5\right)[/tex]

[tex]m=\frac{-5-10}{14-8}[/tex]

[tex]m=-\frac{5}{2}[/tex]

Therefore, the slope between (8, 10) and (14, -5) will be:

Answer:

The distributive property of multiplication states that a ( b + c ) = a b + a c . It's often used for equations when the terms within the parentheses can't be simplified because they contain one or more variables.

Answer:

  y = 0.5x +14

Step-by-step explanation:

If we let x and y represent the number of chores and Hari's allowance, respectively, then we have the two points (16, 22) and (4, 16). We can use the 2-point form of the equation for a line to find the equation.

  y = (y2 -y1)/(x2 -x1)(x -x1) +y1

  y = (16 -22)/(4 -16)(x -16) +22 . . . . substitute

  y = -6/-12(x -16) +22 . . . . simplify

  y = 1/2x -8 +22 . . . . eliminate parentheses

  y = 0.50x +14
