The percentage discount for the pair of sneakers is 10%.

A percentage is a value per hundredth. Percentages can also be fractions and decimals by decimals by dividing by 100 and vice versa. To obtain a percentage of a given value we divide the given percentage by a hundred and multiply the value with it.

The percentage discount can be determined by putting the discounted value upon the price multiplied by a hundred and subtracting the obtained percentage from the hundred percentage.

∴ The percentage discount on the pair of sneakers is,

= (22.50/25)×100.

= 0.9×100.

= 90%.

So, the percentage discount is (100 - 90)% = 10%.

Step-by-step explanation:

It is assumed you are looking for the missing value of r.

Use the intersecting secants theorem:

Substitute known values and solve for r:

Answer:

(a) FB = 24 cm

(b)  r = 10

Step-by-step explanation:

Find the length, in cm, of FB.

Intersecting Secant and Tangent Theorem

When a secant segment and a tangent segment meet at an exterior point, the square of the measure of the tangent segment is equal to the product of the measures of the secant segment and its external secant segment.

Given:

[tex]\begin{aligned}\implies FB^2 & =FE \cdot FD\\FB^2&=32 \cdot 18\\FB^2&=576\\\sqrt{FB^2}&=\sqrt{576}\\FB&=24\end{aligned}[/tex]

Therefore, the length of FB is 24 cm.

Find the value of r.

Triangle FBO is a right triangle with side lengths:

Pythagoras Theorem

[tex]a^2+b^2=c^2[/tex]

where:

Therefore, substitute the side lengths of triangle FBO into Pythagoras Theorem and solve for r:

[tex]\begin{aligned}\implies BO^2+FB^2&=OF^2\\r^2+24^2&=(r+16)^2\\r^2+576&=r^2+32r+256\\576&=32r+256\\32r&=320\\r&=10\end{aligned}[/tex]

Therefore, the value of r is 10.

The correct option D) Add 48 to 52 is the conjecture that describes for the  7th term in the sequence.

For the given question, the sequence is given as;

4, 20, 36, 52,

Where, the first term a₁ is 4.

Second term a₂ is 20 and,

Third term a₃ is 36

Common difference d for each case is;

d = a₂ - a₁

d = 20 - 4 = 16

d = a₃ - a₂

d = 36 - 20 = 16

as, common difference is same, the sequence is said to be in AP.

Then, the formula for finding the 7th term is -

a₇ = a₁ + 6d

a₇ = 4 + 6×16

a₇ = 100

Now, this 7th term from the options can be found as;

Add 48 to 52 = 100.

Step-by-step explanation:

i dont see this as an option but i believe that there was a mistake i dont believe that any of theese are correct

The total cost of the hire purchase for the bicycle is  $19,145.

The difference between the hire purchase price and the cost price for the bicycle is  $2,825.50

The difference as a percentage of cash price 17.31%.

The total cost of the hire purchase is the sum of the deposit and the total monthly instalment.

Total cost of the hire purchase = amount deposited + total instalment paid

Total instalment paid = number of month x payment per month

$1224.50 x 10 = $12,245

Total cost of the hire purchase = $6,900 +  $12,245 = $19,145

The difference = cost of hire purchase + cash price

$19,145 - $16 319.50 = $2,825.50

The difference as a percentage of cash price = (2,825.50 / $16,319.50) x 100 = 17.31%

The three relations given all represent functions because each has exactly one y-value that corresponds to each x-value.

A relation can be defined as a function if the x-values (input/domain element) each has exactly one y-value (output value/range element) that is related to or it corresponds to.

A function can have two x-values that have the same y-value but cannot have two y-values that corresponds to one x-value.

In the first relation showing a graph, each x-value on the graph has exactly one y-value it corresponds to. Therefore, it is a function.

In the second relation that is represented by the set of ordered pairs, every x-value also have only one y-value it is related to. Therefore, it represents a function.

The third function given shows a table of values of a relation that has exactly only one y-value that is assigned or related to each x-value. This also is a relation that represents a function.

Answer:

s:[-2,-3] is the answer

The set S:{ - 2 , - 3 } will make the inequality 2p - 8 < 5p + 4 true

What is an Inequality Equation?

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.

Given data ,

The set S : { - 2 , - 3 , - 4 , - 5 }

The inequality relation is 2p - 8 < 5p + 4

Now , substituting the value from set S in the inequality , we get

When p = - 2 :

2p − 8 < 5p + 4

2(-2) − 8 < 5(-2) + 4

-4 − 8 < -10 + 4

-12 < -6  TRUE

When p = - 3

2p − 8 < 5p + 4

2(-3) − 8 < 5(-3) + 4

-6 − 8 < -15 + 4

-14 < -11  TRUE

When p = - 4

2p − 8 < 5p + 4

2(-4) − 8 < 5(-4) + 4

-8 − 8 < -20 + 4

-16 < -16  FALSE

When p = - 5

2p − 8 < 5p + 4

2(-5) − 8 < 5(-5) + 4

-10 − 8 < -25 + 4

-18 < -21  FALSE

Therefore , the value of p = - 2 , - 3 will satisfy the given inequality relation

Answer:

y = 4x+2

Step-by-step explanation:

To find an equation that runs through (-4,1) and (4,3) first find the difference between the two y numbers and x number to find the slope. between the two y numbers you go left or right 8 units, and difference between the two x numbers, which is 2. making the slope 4. looking at a graph and marking the two points, draw a line connecting the two given points, find the y intercept. the y intercept is at coordinates (0, 2) making the y intercept 2. making that into an equation is y = 4x + 2

Answer:

slope of 1/2

Step-by-step explanation:

x-2y=-18

First, get the equation in slope intercept form

y = mx+b  where m is the slope and b is the y-intercept

-2y = -x -18

Divide each side by -2

y = 1/2 x + 9

The slope is 1/2

Parallel lines have the same slope, so lines that are parallel will have a slope of 1/2

Answer:

3 seconds

Step-by-step explanation:

We can solve this in either of two ways:  Graphing or taking the first derivative,  I'll use both,

Graphing

Plot the equation.  My DESMOS graph is attached.  One can find the vertex of this curve at 3 seconds.  Bonus:  It reaches a height of 144 units at this point.

Derivative

The first derivative of this function will produce an equation that returns the slope of the line at any point x.

S(t) = 96t - 16t^(2)

S'(t) = 96 - 2*16t

S'(t) = 96 - 32t

The slope of the curve will be 0 when the ball reaches it's maximum height and begins to fall.  Since we want the time it takes to reach a slope of zero, we can set S'(t) to 0 and solve:

S'(t) = 96 - 32t

0 = 96 - 32t

32t = 96

t = 3 seconds

3:5 is equivalent to Aiyana’s ratio

Since 3 and 5 are both prime numbers, you must multiply them by the same number (or any other integer) in order to have a ratio that is the same as Aiyana's. Ex 3:5=6:10=9:15 etc. The three ratios are identical.

A ratio displays the multiplicity of two numbers. For instance, if a dish of fruit contains eight oranges and six lemons, the ratio of oranges to lemons is eight to six. The ratio of oranges to the overall amount of fruit is 8:14, while the ratio of lemons to oranges is 6:8.

The streets where Elmwood and Taylor drive are neither perpendicular nor parallel.

Elmwood Drive passes through R(4,-11) and S(0,-9)

Slope of this line is (y₁-y₂)/(x₁-x₂)

Here (x₁,y₁) is (4,-11) and (x₂,y₂) is (0,-9)

slope of this line is (-11 - (-9))/(4-0)

= (-11 + 9)/4

= -2/4 = -1/2

Taylor Road passes through J(6,-2) and K(4,-5)

Slope of this line is (y₁-y₂)/(x₁-x₂

Here (x₁,y₁) is (6,-2) and (x₂,y₂) is (4, -5)

slope of this line is (-2 - (-5))/(6 - 4)

= (5 - 2)/2

= 3/2

The slopes of both the line is not same, so they are not parallel.

The product of slopes of both the lines is equal to 1, then it can be said as perpendicular lines.

The product of slope of streets passed by Elmwood and Taylor is

- 1/2 x 3/2 = -3/4

The result is not equal to 1, so they are not perpendicular lines.

Therefore, the streets where Elmwood and Taylor drive are neither perpendicular nor parallel.
