Can anybody help me on this i don't get it

Answer:

18%

Step-by-step explanation:

Express the ending population as a percentage of the starting population:

270000 divided by 330000=0.82

0.82 *100=82

subtract from the 100% we started with to get the percent decrease:

100% - 82% = 18

Answer:

1. 2268.

2. 12.

Step-by-step explanation:

1. Given the mathematical expression; 2 * 2 * 9 * 7 * 9

We would simplify the expression;

2 * 2 * 9 * 7 * 9 = 4 * 81 * 7

2 * 2 * 9 * 7 * 9 = 28 * 81

2 * 2 * 9 * 7 * 9 = 2268

2. Given the mathematical expression; 2² + 2 * 2²

From BODMAS (Bracket Of Division Multiplication Addition Substraction), we would first of all multiply before performing an addition operation.

Therefore,

2² + 2 * 2² = 4 + 2 * 4  

2² + 2 * 2² = 4 + 8

2² + 2 * 2² = 12

Answer:

1. 2268 2. 12

No,  5/8 cannot make the equation [tex]\frac{8}{15}-x=\frac{3}{7}[/tex] to be true

The given fractional equation is:

[tex]\frac{8}{15}-x=\frac{3}{7}[/tex]

To calculate the fraction that will make the equation [tex]\frac{8}{15}-x=\frac{3}{7}[/tex], solve for x in the given equation:

[tex]\frac{8}{15}-x=\frac{3}{7}[/tex]

Collect like terms

[tex]x=\frac{8}{15}-\frac{3}{7}[/tex]

Simplify the resulting fraction as follows:

[tex]x=\frac{56-45}{105} \\\\x=\frac{11}{105}[/tex]

Therefore, the missing fraction that will make the equation [tex]\frac{8}{15}-x=\frac{3}{7}[/tex] true is 11/05

We can conclude that 5/8 cannot make the equation [tex]\frac{8}{15}-x=\frac{3}{7}[/tex] to be true

Since [tex]\frac{5}{8} \neq\frac{11}{105}[/tex], hence [tex]\frac{5}{8}[/tex] will not make the equation true.

Given the equation

a is the fraction that will make the equation to be equal

Subtract [tex]\frac{8}{15}[/tex] from both sides;

[tex]\frac{8}{15}-a-\frac{8}{15} =\frac{3}{7}-\frac{8}{15}\\-a= \frac{3}{7}-\frac{8}{15}\\-a=\frac{3(15)-7(8)}{105} \\-a=\frac{45-56}{105}\\-a=\frac{-11}{105}[/tex]

Multiply both sides by a negative sign to have:

[tex]-(-a)=-(-\frac{11}{105} )\\a=\frac{11}{105}[/tex]

Since [tex]\frac{5}{8} \neq\frac{11}{105}[/tex], hence [tex]\frac{5}{8}[/tex] will not make the equation true.

Answer: (12, 5)

Step-by-step explanation:

3x + 2y = 46 x + y = 17

Subtract y from both sides of the equation.

x = 17 − y 3x + 2y = 46

Replace all occurrences of x with 17 − y in each equation.

   51 − y = 46

x = 17 − y

Solve for y in the first equation.

Move all terms not containing y to the right side of the equation.

Subtract 51 from both sides of the equation.

   −y = 46 − 51

   x = 17 − y

Subtract 51 from 46.

   −y = −5

   x = 17 − y

Multiply each term in −y = −5 by −1

Multiply each term in −y = −5 by −1. (−y) ⋅ −1 = (−5) ⋅ −1

   x = 17 − y

Multiply (−y) ⋅ −1.

   y = (−5) ⋅ −1

   x = 17 − y

Multiply −5 by −1.

y = 5

x = 17 − y

Replace all occurrences of y with 5 in each equation.

Replace all occurrences of y in x = 17 − y with 5. x = 17 − (5)

y = 5

Simplify 17 − (5).

Multiply −1 by 5.

x = 17 − 5

y = 5

Subtract 5 from 17.

x = 12

y = 5

The solution to the system is the complete set of ordered pairs that are valid solutions.

Step-by-step explanation:

Answer:

the value of x is 25 degrees

Step-by-step explanation:

Here, we want to get the value of x

we use an important triangle angular principle here

And the principle is that when we add two opposite interior angles, we get the value of the exterior angle on the third side

Thus, mathematically;

x + 75 = 4x

4x-x = 75

3x = 75

x = 75/3

x = 25 degrees

It is a acute triangle

Answer:

[tex]y = \frac{3}{2} x + 13[/tex]

Step-by-step explanation:

1) Use point-slope formula [tex]y-y_1 = m (x-x_1)[/tex] to find the slope-intercept form (or y = mx + b form) of the equation. m represents the slope, and [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of a point the line intersects. So, substitute [tex]\frac{3}{2}[/tex] for m, -4 for [tex]x_1[/tex], and 7 for [tex]y_1[/tex]. Then, simplify and isolate y on the left side like so:

[tex]y-(7) = \frac{3}{2} (x - (-4)) \\y -7 = \frac{3}{2} (x + 4) \\y - 7 = \frac{3}{2} x + 6\\y = \frac{3}{2} x + 13[/tex]

Answer:

x = 45.6

Step-by-step explanation:

NOTE: Please double-check my answer.

To find x, I used Sine Law.

[tex]\frac{x + 5}{sin65}[/tex] = [tex]\frac{x}{sin40}[/tex]

(x+5)sin40 = xsin65

xsin40+ 5sin40 = xsin65

xsin40 - xsin65 = -5sin40

x(sin40 - sin65) = -5sin40    (I factored out the "x")

x = [tex]\frac{-5sin40}{sin40 - sin65}[/tex]

x = [tex]\frac{-3.725565802}{0.74511316 - 0.826828679}[/tex]

Answer:

Alex is reading faster by 5 more pages per hour.

Step-by-step explanation:

Alex's rate of reading is 1/2 pages per minute, or 1 page every 2 minutes. To convert his rate to pages per hour, we can divide 60 (minutes in an hour) by 2 (minutes it takes Alex to read a page) which is equal to 30 (pages read in an hour). Therefore, Alex is reading at 30 pages an hour and reading 5 more pages an hour than Sammie.

Answer:

1). Yes

2). Yes

3). No

Step-by-step explanation:

1). y = 3

  We can rewrite this equation in the slope-intercept form as,

   y = 0.x + 3

  Here, slope = 0

  y-intercept = 3

  Therefore, it's a linear relation.

  YES.

2). 2x - 5y = 10

   5y = 2x - 10

   y = [tex]\frac{2}{5}x-2[/tex]

   Therefor, it's a linear function.

   YES

3). y = x(x + 3)

   y =x² + 3x

   Since, this equation is a quadratic equation,

   It's not a linear function.

   NO

Answer:

For 1 copy it takes 5 seconds, for 2 copy it takes 7 seconds, and for 3 copy it takes 9 seconds.

For each copy, it takes 2 seconds more.

Step-by-step explanation:

A teacher is making multiple copies of a 1-page homework assignment. The time it takes her in seconds is 2 times the number of copies she makes plus 3. What is the total number of seconds it takes for the teacher to make 1 copy? 2 copies? 3 copies? By how many seconds does the total time increase for each copy?

Let the number of copies represented by x and y is the time taken.

The time It takes her in seconds is 2 times the number of copies she makes plus 3.

So the required equation is [tex]y=2x+3[/tex].

To calculate the time taken for the first copy put x=1 in the above equation.

[tex]y=2(1)+3[/tex]

[tex]y=5[/tex]

To calculate the time taken for the first copy put x=2 in the above equation.

[tex]y=2(2)+3[/tex]

[tex]y=7[/tex]

To calculate the time taken for the first copy put x=3 in the above equation.

[tex]y=2(3)+3[/tex]

[tex]y=9[/tex]

Hence, For each copy, it takes 2 seconds more.

Answer:

[tex]12x\leq 24[/tex]; [tex]x\leq 2[/tex]

Step-by-step explanation:

So you have 12 math problems that each take x amount of minutes, and have 24 minutes to finish them. Remember, you can't exceed the 24 minutes (but you are allowed to equal that time). So:

[tex]12x\leq 24[/tex]

Then you can simplify by dividing both sides by 2:

[tex]x\leq 2[/tex]

Step-by-step explanation:

By Exterior Angle Theorem, the sum of the 2 inner angles of the triangle is equal to the exterior angle by a straight line.

Therefore we have x + 72° = 90° + 34°.

=> x + 72° = 124°, x = 52°.

Hence the value of x is 52°.

Answer:

Step-by-step explanation:

Step-by-step explanation:

[tex] \tt{3x + 8 = 2x - 8}[/tex]

We want to get all the constants on the right hand side of the equation. So , Add 8 on both sides of the equation.

⤏ [tex] \tt{3x + 8 + 8= 2x - 8 + 8}[/tex]

⤏ [tex] \tt{3x + 16 = 2x}[/tex]

Move 2x to left hand side and change it's sign. Similarly , Move 16 to right hand side and change it's sign :

⤏ [tex] \tt{3x - 2x = - 16}[/tex]

Since , 3x and 2x are like terms , they can be added or subtracted. Subtract 2x from 3x :

⤏ [tex] \sf{x = - 16}[/tex]

[tex] \red{ \boxed{ \boxed{ \tt{Our \: final \: answer : \boxed{ \underline{ \tt{x = - 16}}}}}}}[/tex]
