Answer:

Im too lazy to put here

Step-by-step explanation:

10% off --> 90% the actual cost

25 x 90% = 22.50

$22.50

20% off --> 80% the actual cost

25 x 80% = 20.00

$20.00

30% off --> 70% the actual cost

25 x 70% = 17.50

$17.50

40% off --> 60% the actual cost

25 x 60% = 15.00

$15.00

50% off --> 50% the actual cost

25 x 50% = 12.50

$12.50

Answer:

1:   −5y+8x=−18  

Slope = 3.200/2.000 = 1.600

 x-intercept = -18/8 = -9/4 = -2.25000

 y-intercept = 18/5 = 3.60000

2:   Slope = -0.800/2.000 = -0.400

 x-intercept = 58/2 = 29

 y-intercept = 58/5 = 11.60000

Step-by-step explanation:

1: Step  1  :

Equation of a Straight Line

1.1     Solve   -5y+8x+18  = 0

Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).

"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.

In this formula :

y tells us how far up the line goes

x tells us how far along

m is the Slope or Gradient i.e. how steep the line is

b is the Y-intercept i.e. where the line crosses the Y axis

The X and Y intercepts and the Slope are called the line properties. We shall now graph the line  -5y+8x+18  = 0 and calculate its properties

Graph of a Straight Line :

Calculate the Y-Intercept :

Notice that when x = 0 the value of y is 18/5 so this line "cuts" the y axis at y= 3.60000

 y-intercept = 18/5  =  3.60000  

Calculate the X-Intercept :

When y = 0 the value of x is -9/4 Our line therefore "cuts" the x axis at x=-2.25000

 x-intercept = -18/8 = -9/4  = -2.25000  

Calculate the Slope :

Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 3.600 and for x=2.000, the value of y is 6.800. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 6.800 - 3.600 = 3.200 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

2: Same thing

Answer:

[tex]t \approx 50.4\,min[/tex]

Step-by-step explanation:

The time constant of the element X is:

[tex]\tau = \frac{13\,min}{\ln 2}[/tex]

[tex]\tau = 18.755\,min[/tex]

The decay function has the following form:

[tex]\frac{m}{m_{o}} = e^{-\frac{t}{\tau} }[/tex]

[tex]t = -\tau \cdot \ln \frac{m}{m_{o}}[/tex]

[tex]t = -(13\,min)\cdot \ln \left(\frac{11\,g}{530\,g} \right)[/tex]

[tex]t \approx 50.4\,min[/tex]

answer3

beacuse to find the x-intercept, substitute in  0  for  y  and solve for  x .

Answer:

x ⠀⠀200⠀⠀ ⠀500

y⠀⠀⠀ 11⠀⠀⠀⠀⠀a

As x directly varies with y

200 × a = 500 × 11

a = 5/2 × 11 = 27.5

Answer:

y = 27.5

Step-by-step explanation:

We know that directly proportional equations usually come in the format of  

y =  k × x  where 'k' is the constant. In this problem we are presented with a directly proportional questions asking us to find y when x= 500 considering that y varies directly with x and x = 200 when y = 11. So let's substitute in the values

→ y = k × x

⇒ Substitute in the first set of values which is x = 200 and y = 11

→ 11 = k × 200

⇒ Divide both sides by 200 to isolate 'k'

→ 0.055 = k

Now we know that the constant is 0.055 we can substitute the second set of values in,

→ y = 0.055 × x

⇒ Substitute in the second value which is x = 500

→ y = 0.055 × 500

⇒ Simplify

→ y = 27.5

If y varies directly with x and x = 200 and y = 11, the value of y when x = 500 is 27.5

Answer:

1/8

Step-by-step explanation:

It's 1/8 because you're halving the radius 3 times. and 1^-3 is 1/8

Answer is in the file attached below. But basically its 1/4 on both sides.

Hope this helps!

Answer:

Step-by-step explanation:

You must assume that N is the center of the circle.

NTP  is a right triangle.

NM is the radius

NT is also a radius

The area of the circle is 25pi

25 pi = pi r^2

r^2 = 25

r = 5

The right angle triangle can be solved by

PT^2 + NT^2 = (r + 4)^2

PT^2 + 25 = (5+4)^2

PT^2 + 25 = 81

PT^2 = 56

PT = sqrt(56)

PT = 7.48

Answer:

f(x) = -4x² + 19x - 18

Step-by-step explanation:

[tex]f(x) = 2x^2 - 1.5x - 5[/tex]

i) If it is translated 2 units in the positive x direction, therefore we use f(x-2)

[tex]y=f(x-2) = 2(x-2)^2 - 1.5(x-2) - 5\\y = 2(x^2-4x+4) - 1.5x+3 - 5\\y=2x^2-8x+8-1.5x+3-5\\y=2x^2-9.5x+6[/tex]

f(x) = 2x² - 9.5x + 6

If it is then translated 3 units in the positive y, we add 3 to the input function to get:

[tex]y=f(x)+3=2x^2-9.5x+6+3\\y = 2x^2-9.5x+9[/tex]

ii) stretched vertically by a factor of 2, we multiply the function by 2 to get:

[tex]y =2( 2x^2-9.5x+9) = 4x^2-19x+18\\y= 4x^2-19x+18[/tex]

iii) reflected across the x-axis

we multiply the parent function by –1, to get a reflection about the x-axis.

[tex]y= -1(4x^2-19x+18)=-4x^2+19x-18\\y=f(x)=-4x^2+19x-18[/tex]

Answer:

Step-by-step explanation:

Step 6: as the line on the line graph moves from left to right, the line falls.

step 7: (idk)

Answer:

See answer for Step 6 below.

Step 7: the slope is "-1/2" (negative 1/2)

Step-by-step explanation:

Step 6: A negative slope means that as the value of the coordinate "x" increases,the value of the coordinate "y" decreases, and the rate of change for points on the line is therefore negative. The line goes "DOWN" as you read the graph from left to right.

In order to calculate the slope, we can use the triangle defined by the points (0, 5), (4, 3)  and (0, 3) as shown in the attached image:

Where the "run" is from 0 to 4 , that is:  4 - 0 = 4

and the rise is negative (from 5 to 3: that is 3 - 5 = -2

Therefore, the rise over the run becomes: -2 / 4 = -1/2

assuming b is the underscript of log, the formula is log _b_3=-8.

the formula for log is usually log_b_x=n, and to convert it to exponential would be the same as b^n=x

just fill in the numbers, b is still b, and -8 will be the in place of n, equal to 3.

b^-8=3

Answer:

x = 6 m

Step-by-step explanation:

The area (A) of a trapezium is calculated as

A = [tex]\frac{1}{2}[/tex] h (a + b)

where h is the perpendicular height and a, b the parallel bases

Here A = 60, h = 8, a = 9 and b = x , thus

[tex]\frac{1}{2}[/tex] × 8 × (9 + x) = 60, that is

4(9 + x) = 60 ( divide both sides by 4 )

9 + x = 15 ( subtract 9 from both sides )

x = 6 m

Answer:

About 2/3 of the animals at the shelter are dogs

Step-by-step explanation:

Let's first transform the mixed number to the corresponding improper fraction.

67 2/3 is equivalent to (3*67 + 2)/3 = 203/3

we are asked to find a fraction equivalent to 203/3%. To do this, we have to divide the fraction by 10, as follows:

203/3% = (203/3)*(1/100) = 203/300 ≈ 2/3

A. [tex]11 + 3\frac{5}{8}[/tex]

Step-by-step explanation:

Subtracting a positive number is like adding a negative number, as in you move to the left on a number line. A negative number is the opposite of the positive, so you move to the right instead, which is equivalent to adding.

Make sure there are parenthesis around the negative number, otherwise, you might be seeing one minus sign as two!

Hope this helps!

Answer:

C= 2 radians.

Step-by-step explanation

Length of arc = r C where r = the radius and C is the angle in radians.

Area of the sector = 1/2 r^2 C

So we have:

30 = rC  and

900 = 1/2 r^2 C

From the first equation we have  r = 30/C so substituting for r:

900 = 1/2 (30/C)^2 * C

900 = 0.50 (900/C^2) * C

900 =  450/C

C= 2 radians.

Answer:

111 boxes

Step-by-step explanation:

He bought 223 feet of wood

Each box will take 2 feet

To determine the total number of box he'll make from 223,

1 box = 2 feet of wood

X box = 223 feet of wood

X = (223 × 1) / 2

X = 111.5 box approximately 112 boxes

But technically, since its 111.5, he'll be able to make 111 boxes completely with 0.5 feet of wood left

130 degrees because x would be 60. 60-10 would be 50 which would make both angles add up to 180.

Answer: The measure of angle TRV is 130 degrees.

Step-by-step explanation:

(x - 10) +  (2x +10) =180

3x = 180

x= 60

2(60) + 10  = 130
