The price of a toy usually costing £50 is increased to £65. Work out the percentage increase.
Unfortunately the answer doesn't seem obvious to me. If i could have the answer as quickly as possible it would be very helpful. Thank you
Answer:
115%
Step-by-step explanation:
115% percent increase in usual value, I may guess see other answrrs too
Answer:
30%
Step-by-step explanation:
The percentage increase is calculated as
[tex]\frac{increase}{original}[/tex] × 100%
increase = £65 - £50 = £15 , then
percent increase = [tex]\frac{15}{50}[/tex] × 100% = 15 × 2% = 30%
Sketch a possible curve of f(x) given the graphs of f ‘ (x) and f’’ (x) below:
Step-by-step explanation:
Graph 1 is a parabola and has 2 x points and a turning point
meaning it has a minimum and a maximum point.
conclave points are the highs and lows, once you show this in table then you can interpreted them on a graph see the examples attached.
Graph 1 is opposite to shown interpreted conclave so instead of --c++
we write + + c - - and draw on quadrant 1 instead of quadrant 3
graph 2 is decreasing so instead of -+ c then + + it would show + - c then - - so the curve stays in quadrant 3 and 4. Also where c is we draw a 0 and say whether it is minimum or maximum point.
Both graph 1 and 2 demonstrate minimum points for their f(x) for c.
so in your workings within the table you write min as seen in red within the attachment. They wrote max, but you write min as you are in decreasing conclave fx values that reach min point c then they increase and become parabolas.

The length of one of the equal sides of an isosceles triangle is 4 cm. If its base is 2 cm, then what is its area?
Answer:
A = 1/2bh
b = 2cm
h will be found using the side of the triangle with Pythagoras theorem
h² + 1² = 4²
h² = 15
h = √15 cm
then,
A = 2*√15

A = √15cm²

true or false? A subtraction expression with a positive integer and a negative can have a difference of zero
Answer:
False
Step-by-step explanation:
Subtracting a negative integer is equivalent to adding a positive integer. So adding a positive integer to a positive integer can never be zero.

What equation, in point-slope form, matches the graphed line shown?
Question 3 options:
y−5=−23(x+9)
y−6=45(x−2)
y−2=−34(x−6)
y+6=45(x+3)
Answer:
Here’s the graph
Step-by-step explanation:
The equation of the line in point-slope form that matches the graph passing through the points (6, 2) and (10, -1) is:
y = (-3/4)x + 13/2
The correct answer is: Option C: y - 2 = -3/4(x - 6).
Here, we have to find the equation of the line in point-slope form that matches the graph passing through the points (6, 2) and (10, -1), we first need to find the slope (m) of the line using the formula:
[tex]m = (y_2 - y_1) / (x_2 - x_1)[/tex]
where [tex](x_1, y_1) = (6, 2) ; (x_2, y_2) = (10, -1)[/tex].
m = (-1 - 2) / (10 - 6)
m = (-3) / 4
Now that we have the slope (m), we can use the point-slope form of the equation of a line:
[tex]y - y_1 = m(x - x_1)[/tex]
Using the point (6, 2):
y - 2 = (-3/4)(x - 6)
Now, simplify the equation:
y - 2 = (-3/4)x + 9/2
Finally, move -2 to the other side to get the equation in the point-slope form (y = mx + b):
y = (-3/4)x + 9/2 + 2
y = (-3/4)x + 9/2 + 4/2
y = (-3/4)x + 13/2
So, the equation of the line in point-slope form that matches the graph passing through the points (6, 2) and (10, -1) is:
y = (-3/4)x + 13/2
The correct answer is: Option C: y - 2 = -3/4(x - 6).

Plot the ordered pairs from the table.
The ordered pair is plotted in the graph attached in the solution.
Given that Timony has three friends, the table shows the time taken by him to reach at his friends place and the distance of the homes of each of his friend.
We need to plot the ordered pair formed by the time and distance on the graph,
The ordered pair are:
(5, 10)
(11, 15)
(18, 20)
Plot the ordered pairs on the graph according to the given values:
The first ordered pair is (5, 10). This means that Timony took 5 units of time to reach a friend's place that is located 10 units of distance away. Mark this point on the graph.The second ordered pair is (11, 15). Timony took 11 units of time to reach a friend's place that is located 15 units of distance away. Mark this point on the graph.The third ordered pair is (18, 20). Timony took 18 units of time to reach a friend's place that is located 20 units of distance away. Mark this point on the graph.Hence the ordered pair is plotted.

Answer:
mark me barinlest
Step-by-step explanation:
supplement angles have sum = 180, complement angles have sum = 90
180-x = 4(90-x)
180-x = 360 -4x
3x = 180
x = 180/3

Supplementary angles sum to 180°.
Let the angle be x then the other angle is 4x.

Which expressions have exactly two factors? Choose ALL that apply.
A) a+ 7
B)4•n•n
C)3(b-1)
D)xy
E)m•m+8
F)2•2•2•2•2
Answer: The answer is F.
Step-by-step explanation: It’s F because the number would be multiplied equally because all of the number are multiplied by 2. The rest of them either have variables or variables with numbers in them, which looks kind of funky, so F is the answer. I hope you get it right :).

Answer:
The number is -100, Jill can think of something else, now.
Step-by-step explanation:
x = the number
x/4 - 20 = -45 {twenty less than one-fourth of the number is -45}
x/4 = -25 {added 20 to each side}
x = -100 {multiplied each side by 4}
Answer:
-31.25
Step-by-step explanation:
Jill's number=[1/4×(-45)]-20
=-11.25-20
=-31.25
when a number divides another number exactly the smaller number is called
Answer:
1) A number that divides another number evenly is called a factor of that number. For example, 16 can be divided evenly by 1, 2, 4, 8, and 16. So the numbers 1, 2, 4, 8, and 16 are called factors of 16.
2) A number that divides a given set of numbers is called a common factor of the numbers.
