Answer:

$11.50

Step-by-step explanation:

Percentage Increase=(Final Value−Starting Value/Starting Value)×100

so its x-7.50/7.50 = 50%

rearranging this it the original price will equal $11.25

Answer:

45 Degrees

Step-by-step explanation:

This would be a right angle. The other side would be 45 Degrees. Which when you add them equals 90.

Answer:

45 degrees

Step-by-step explanation:

The following figure shown is a square

All of the angles in a square are right angles meaning that they equal 90

If a diagonal line cuts through the middle then it splits the right angle into to 45 degree angles therefore your answer is 45 degrees

Given:

Line segment XY is located at X(2, 6) and Y(4,8).

The line segments is dilated by a scale factor of 2 with a center of dilation of T(-3, 4).

To find:

The coordinates of X'

Solution:

If a figure dilated by a scale factor k with a center of dilation (a,b), then the rule of dilation is:

[tex](x,y)\to (k(x-a)+a,k(y-b)+b)[/tex]

The line segments is dilated by a scale factor of 2 with a center of dilation of T(-3, 4). So, the rule of dilation is

[tex](x,y)\to (2(x-(-3))+(-3),2(y-4)+4)[/tex]

[tex](x,y)\to (2(x+3)-3,2y+2(-4)+4)[/tex]

[tex](x,y)\to (2x+6-3,2y-8+4)[/tex]

[tex](x,y)\to (2x+3,2y-4)[/tex]

The coordinate of X are (2,6).

[tex]X(2,6)\to X'(2(2)+3,2(6)-4)[/tex]

[tex]X(2,6)\to X'(4+3,12-4)[/tex]

[tex]X(2,6)\to X'(7,8)[/tex]

Therefore, the coordinates of X' are (7,8).

Answer:

the third one

Step-by-step explanation:

bc like there are 2 boxes of 1 and 5 boxes of 1/6 so thats already 2 and 5/6 which applies to all of them. then there is 1 box of 1 and 2 boxes of 1/3 so thats 1 and 1/3 which applies to all of them also but when you make them have the same denominator you get 2 and 5/6 + 1 and 4/6 which deletes the second one. When you add you should get the same denominator so that deletes the first one so then you simplify that and the fraction should still be equal to the unsimplified fraction so you should get 4 and 1/2 if that makes sense

Answer:

2280

Step-by-step explanation:

As in understandable steps,

1512x12 = 18144

18144 / 7

= 2592

2592 - 312

= 2280

An equation is formed of two equal expressions. John's salary before the pay raise is $2280.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Let the pay of John before the raise be x.

As it is stated that John's pay was increased by $312. And he saves 7/12 of his pay which is equal to $1512. Therefore, the equation that can represent the current saving John has,

[tex]\dfrac{7}{12}(x+312)=1512\\\\(x+312) = \dfrac{1512 \times 12}{7}\\\\x+312= 2592\\\\x =2592-312\\\\x = 2280[/tex]

Hence, John's salary before the pay raise is $2280.

Answer:

a-10 - 6/a+2

Step-by-step explanation:

The simplification of the expression (a²- 8a - 26) / (a + 2) is (a - 10) - 6/(a + 2).

The number system is a way to represent or express numbers.

A decimal number is a very common number that we use frequently.

Since the decimal number system employs ten digits from 0 to 9, it has a base of 10.

As per the given b,

(a²- 8a - 26) / (a + 2)

First quotient = a

Remainder = -10a - 26

Second quotient = -10

Remainder = -6

By quotient remainder theorem,

(a²- 8a - 26) = (a + 2)(a - 10) - 6

Thus,

[(a + 2)(a - 10) - 6]/(a + 2) = (a - 10) - 6/(a + 2)

Hence "The simplification of the expression (a²- 8a - 26) / (a + 2) is (a - 10) - 6/(a + 2)".

Answer:

Population of wolves in 2016 = 23

Step-by-step explanation:

Equation of the line of best fit has been given as,

y = 1.5x - 1

Here, y = population of a pack of wolves

x = duration (in years) since year 2000

Duration between year 2000 and 2016 = 16 years

Now we substitute the value x = 16 in the equation of line of best fit,

y = 1.5(16) - 1

y = 24 - 1

y = 23

Therefore, population of wolves in 2016 = 23
