Steph makes and sells birthday cakes. Each cake costs £54 to make.
She makes a profit of 15% on each cake.
What is the selling price of Steph's birthday cakes?
(2 marks)
£=
Answers
The selling price of Steph's birthday cakes such that the profit is 15% will be £62.1.
What is the percentage?The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.
As per the given,
Cost per cake = £54
15% of £54 = 0.15 x 54 = £8.1
Selling price = £54 + £8.1 = £62.1
Hence "The selling price of Steph's birthday cakes such that the profit is 15% will be £62.1".

. When 12 is subtracted from 4 times a number, the result is 24. Which equation can be used to find the number?
Answers
Answer:
12 + 24 divided by 4
Step-by-step explanation:
12 + 24 is 36, so divide that by 4, that gives you the answer, which is 9
The equation that represents the situation is 12 - 4x = 24. Then the solution of the equation will be negative 3.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
When 12 is subtracted from 4 times a number, the result is 24.
Let the number be 'x'. Then the equation is given as,
12 - 4x = 24
Simplify the equation, then we have
12 - 4x = 24
- 4x = 24 - 12
- 4x = 12
4x = - 12
x = - 12 / 4
x = - 3
The equation that represents the situation is 12 - 4x = 24. Then the solution of the equation will be negative 3.

A wire 45 meters long is cut into two pieces, One piece is 5 meters longer than the other. What is the length of the two pieces? Create an equation and solve .
Answers
Given:
A wire 45 meters long is cut into two pieces
One piece is 5 meters longer than the other.
To find:
The length of the two pieces.
Solution:
Let length of one piece be x.
One piece is 5 meters longer than the other. So,
Length of another piece = x+5
Total length of wire is 45. So,
[tex]x+(x+5)=45[/tex]
[tex]2x+5=45[/tex]
Subtract 5 from both sides.
[tex]2x=45-5[/tex]
[tex]2x=40[/tex]
Divide both sides by 2.
[tex]x=\dfrac{40}{2}[/tex]
[tex]x=20[/tex]
Now,
Length of one piece = 20 meters
Length of another piece = 20 + 5
= 25 meters
Therefore, the length of two pieces are 20 and 25 meters.

January 30,2019 was the coldest day in minieapolis-St. Paul in over 20 years. The lowest tempeauture recorded that day was -28F. The warmest temperature was 15 higher
Answers
Answer:
The warmest temperature was -13FStep-by-step explanation:
We are expected to compute the warmest temperature recorded at Minneapolis
Step one:
We are told that on January 30th of 2019 was the coldest day at Minneapolis
hence the temperature reading= -28F------this is like 28 points away from 0 on the number line
Step two:
We are given that the warmest temperature recorded is 15F higher.
since the -ve sign represent cold or snowy weather, the warm temperature
is gotten by adding 15F to the negative temperature
=-28+15
= -13F
The warmest temperature was -13F

an equation of the line with a slope of 2/3 and y-intercept of −8.
Answers
Answer:
y = 2/3x - 8
Step-by-step explanation:
Use the slope intercept form, y = mx + b, where m is the slope and b is the y intercept
Plug in the slope and y intercept:
y = mx + b
y = 2/3x - 8
So, y = 2/3x - 8 is the equation of the line.

Base is 40 ft (horizontal length)
Height is 83 ft (vertical height)
A = [tex]\frac{1}{2}[/tex](b x h)

Step-by-step explanation:
If we assume the short vertical edge at top center is 10 yards, as it was in two previous problems with this geometry, then we can find the area of the present parking lot as ...
(x-2)(3x) + x(3x -10) +2x(40) = 6x^2 +64x
where the left vertical rectangle is 3x high and x-2 wide; the center area between vertical rectangles is (2x-2)-(x-2) = x wide and (3x-10) high; and the right vertical rectangle is (x-2 +3x)-(2x-2) = 2x wide and 40 high.
As we said, the right vertical rectangle is 2x wide, so the area that has P as one of its dimensions is ...
A = LW = P(2x)
We want this to be the same as the existing area, so ...
2Px = 6x^2 +64x
P = 3x +32 . . . . . divide by 2x

x+59 = 52º
x+51 = 44º
Step-by-step explanation:
84 + (x+59) + (x+51) = 180º
180 - 84 = 96
x+59 + x+51 = 96
2x + 110 = 96
2x = -14
x = -7
proof:
-7+59 = 52º
-7+51 = 44º
the sum of angles in a triangle must be 180º so:
84 + 52 + 44 = 180
Answer:
∠A = 44°Step-by-step explanation:
84 + x + 59 + x + 51 = 180
2x = 180 - 84 - 59 - 51
x = -14/2
x = -7
∠A = x + 51
∠A = -7 + 51
∠A = 44°
