Following the order of operations, exponents should be simplified after completing all multiplication and division. True False well PEMDAS ^ its 2nd in line... i dont understand what they mean

Unless the exponet is on the outside of a parentheses then the exponet should be done first.

Example

(5x5)^2 - Inside the parentheses should be done first
and it ends up being - 625

But if the exponet is on the inside

(5x5^2) Then do the math for the exponet first
Then it becomes - 125

Braden has 10 red model cars, which are 2/5 of the total number of cars in his collection. How many cars does Braden have in his collection? A) 4 B) 10 C) 25 D) 50

25 cars, because if 10 cars = 2/5 of his collection that means 5 cars are 1/5. Since 1/5 x 5 = 1, that means there are 25 cars in his collection. (5x5 = 25)

A boat that costs $8550 decreases in value by 12% per year. How much will the boat be worth after 3 years?

You have to take $8,550 times 0.12 (12%) to find out the number it is being decreased by.
8,550 x 0.12 = 1,026
And then, you have to subtract 1,026 from 8,550 three times for three years and your answer becomes 5,472.
$5,472

The digit in my hundreds place and the digit in my ones place are the same. The digit in my tens place is 1. The digit in my ones place is 5 more than 2. What number am I

The number is 717, 
You would simply get the answer by looking at all context clues. Hundreds = same as digit in ones, which is 700. Tens = 10. And ones = 7. Therefore, your answer would be 700. Also can be put as 700 + 10 + 7 = 717.

QUESTION POSTED AT 23/09/2019 - 04:25 AM

On a recent day, 8 euros were worth $9 and 24 euros were worth $27. Write an equation of the form y = kx to show the relationship between the number of euros and the value in dollars.

Y = kx
We have to find k value, so lets say x is euros and y is American dollars
so we have
9 = k(8)
k = 1.125
so the equation will be  y = 1.125x
to prove it use another value given
y = 1.125x
y = 1.125 (24)
 y = 27
Thus 24 euros is 27 dollars.
Hence the equation y =1.125x is correct.

You are given the table below. x 4 8 12 16 20 f(x) 11 25 16 9 31 Use the table and n = 4 to estimate the following. Because the data is not monotone (only increasing or only decreasing), you should sketch a possible graph and draw the rectangles. 20 (integral) f(x)dx 4

Solution:

X      4      8       12       16          20

F(x)   11      25      16       9           31

A function is said to be increasing if , x_{1}> x_{2}, then f(x_{1})>f(x_{2}) {\text{and decreasing if } x_{1}> x_{2}, then f(x_{1})<f(x_{2}).

As you can see from the table given as x increases , f(x) increases as well as decreases.

So it is increasing as well as decreasing function.

Now plotting the graph on two dimensional coordinate plane and drawn perpendicular from these points on X axis.

\int_{4}^{20}f(x)dx=\int_{4}^{8}f(x)dx+\int_{8}^{12}f(x)dx+\int_{12}^{16}f(x)dx+\int_{16}^{20}f(x)dx

Equation of line joining two points (x_{1},y_{1}), and (x_{2},y_{2}) is \frac{y-y_{1}}{x-x_{1}}=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

Equation of line joining two points (4,11) and (8,25) is

4(y-11)=14(x-4)

4 y -44 = 14 x -56

4 y = 14 x -12

y= \frac{7x}{2}-3 --------(1)

Area under line (1) is

\int_{4}^{8}f(x)dx=\int_{4}^{8}(\frac{7x}{2}-3) dx=\frac{7x^2}{4}-3x\left \{ {{x=8} \atop {x=4}} \right. =112-24-28+12=72

Equation of line joining (8,25) and (12,16) is

4(y-25 )= -9(x-8)

4 y - 100= -9 x + 72

4 y = -9 x + 172

y = \frac{-9x}{4} +43--------(2)

Area under line 2 is

\int_{8}^{12}f(x)dx=\int_{8}^{12}(\frac{-9x}{4} +43)dx=\left \{ {{x=12} \atop {x=8}}   \frac{-9x^2}{8} +43x = -162 +516+72-344=82

Equation of line joining (12,16) and (16,9) is

-4(y-16) = 7(x-12)

-4 y + 64= 7 x -84

-4 y = 7 x -148

y = \frac{-7x}{4} +37-----------(3)

Area under the line 3 is

\int_{12}^{16}f(x)dx=\int_{12}^{16}(\frac{-7 x}{4} +37)dx=\left \{ {{x=16} \atop {x=12}}   \frac{-7x^2}{8} +37 x = -224 +592+126-444=50

Equation of line joining (16,9) and (20,31) is

4(y-9) = 22(x-16)

4 y - 36 = 22 x - 352

4 y = 22 x - 316

y= \frac{11x}{2}-79---------(4)

Area under the line 4 is

\int_{16}^{20}f(x)dx=\int_{16}^{20}(\frac{11 x}{2} -79)dx

=\left \{ {{x=20} \atop {x=16}}   \frac{11x^2}{4} -79 x = 1100-1580-704+1264=2364-2284=80


Total Area = Area under the line (1+2+3+4)

=\int_{4}^{20}f(x)dx=\int_{4}^{8}f(x)dx+\int_{8}^{12}f(x)dx+\int_{12}^{16}f(x)dx+\int_{16}^{20}f(x)dx

= 72 +82+50+80

= 284 square units

You can find area using the formual of area of trapezoid which is = \frac{1}{2}[Sum of parallel sides]× [perpendicular distance between them]

Which inequality can be used to find the maximum number of fill-ups she can purchase during the rest of the month, assuming each fill-up costs $30 A. 30n + 60 ≥ 150 B. 30n + 60 ≤150 C. 60n + 30 ≤ 150 D. 60n + 30 ≥ 150

Answer: B.  30n + 60 \leq150

Step-by-step explanation:

Given : Nala can spend no more than $150 per month on gasoline.

She has already purchased $60 in gas this month.

The cost of each fill-up = $30

Let x be the number of fill-ups she can purchase during the rest of the month.

Then , the cost of fill-ups she can purchase during the rest of the month = 30x

Then , the inequality can be used to find the maximum number of fill-ups she can purchase during the rest of the month is given by :-

30n + 60 \leq150
