2 biscuits cost 80p how much do 12 cost
Well to find how much 12 biscuits cost, you must first find how much each biscuit costs. Therefore, you divide 80p by 2, and get 40p. Then multiply 40p by 12 (the total amount of biscuit). You get the answer, which is 480p.

Answer:
It would be 2%
Step-by-step explanation:
Hope this helps! :D
The simple annual interest rate for this loan will be 2%.
What is the definition of simple interest?Simple interest is extra money paid by the person borrowing the money. The formula for the simple interest is;
[tex]\rm SI = \frac{P \times R \times T}{100}[/tex]
Given data;
P(Principal) =$1500
R(Rate)=?
T)TIme)=5year
SI(Simple interest)=$ 150
The simple interest is calculated as ;
[tex]\rm SI = \frac{P \times R \times T}{100} \\\\ 150 = \frac{1500 \times R \times 5 }{100} \\\\ R=2 \%[/tex]

Tom is trying to write 3/47 As a decimal. He used long division and divided until he got the quotient 0.638297872, at which point he stopped. Since the decimal doesn’t seem to terminate or repeat, he concluded that 3/47 is not rational. Do you agree or disagree? Why?
Answer:
3/47 is rational because it is a ratio of two integers.

You can straight away discard answer D because it is less than both 5/12 and 5/11.
Also you can discard Answer C because 25/264 is very small (less than 1/10=0.1)
[tex]\frac{11}{23} =0.4782[/tex], therefor this is not in between those two numbers.
Then it has to be [tex]\frac{115}{264} =0.4356[/tex]

What is the length of leg y of the right triangle?
A right triangle with hypotenuse 85 and legs 84 and y
Solution :
Given a right triangle with hypotenuse 85 and legs 84 and y.
Use Pythagoras theorem, to find the length of the leg y of the right triangle.
According to Pythagoras theorem,
[tex](hypotenuse)^{2} = leg_{1}^{2}+leg_{2}^{2}[/tex]
As given in the question,
[tex]hypotenuse = 85 \\\\leg_{1} = 84\\\\leg_{2} = y[/tex]
Put these values,
[tex]\Rightarrow 85^{2}=84^{2} +y^{2} \\\\\Rightarrow y^{2}=85^{2}-84^{2}\\\\\Rightarrow y =\sqrt{85^{2}-84^{2}} \\\\\Rightarrow y =\sqrt{169}\\\\\Rightarrow y =13[/tex]
Hence, the length of leg y =13.
Answer:
The length of leg y=13

The same four friends buy tickets for two shows on consecutive nights. They use a coupon for $5 off each ticket. They pay a total of $416 for 8 tickets. Write and solve an equation to find the original price of the tickets.
Answer:
Original price of the ticket was $57.
Step-by-step explanation:
Four friends buy tickets for two shows.
Let the price of a ticket was $c
Then cost of 4 tickets = $4c
They use a coupon to get the discount = $5 on each ticket
So total discount on 4 tickets = 4×5 = $20
Cost of the tickets after discount = 4c - 20
Cost of the tickets for two consecutive nights = 2(4c - 20)
If they paid total amount = $416 for 8 tickets
Then the equation will be 2(4c - 20) = 416
Now we can solve this equation to get the original price of the ticket.
2(4c - 20) = 416
4c - 20 = 208
4c = 208 + 20
4c = 228
c = [tex]\frac{228}{4}[/tex]
c = $57
Therefore, original price of a ticket was $57.
Answer:
57

How do I solve w-w*2+-2w*2
Answer:
See two different cases, below:
Step-by-step explanation:
You cannot "solve" w-w*2+-2w*2, because this is not an equation. Rather, you want to simplify w-w*2+-2w*2 by combining like terms. You have w - 2w - 4w, or -5 w.
If, however, you meant "exponentiation" by " * " then you have w^1 - w^2 - 2w^2, which in turn equals w - 3w^2, or, in descending order by powers of w, -3w^2 + W.
Solve for sss.
0.5s+1=7+4.5s
The value of s from the given equation is -1.5.
The given equation is 0.5s+1=7+4.5s.
We solve the given equation for s.
What is an equation?Equations are mathematical statements containing two algebraic expressions on both sides of an 'equal to (=)' sign. It shows the relationship of equality between the expression written on the left side with the expression written on the right side. In every equation in math, we have, L.H.S = R.H.S (left hand side = right hand side). Equations can be solved to find the value of an unknown variable representing an unknown quantity.
Now, the given equation can be solved as follows:
0.5s+1=7+4.5s
⇒0.5s-4.5s=7-1
⇒-4s=6
⇒s=-6/4
⇒s=-1.5
Therefore, the value of s is -1.5.

What is the exact circumference of a circle with a diameter of 43 cm in terms of pi?
So the corcumference is equal to the diameter tiems pi.
Youre given the diameter, so just multiply it by pi.
The answer is 43pi.
The circumference of a circle with a diameter of 43 cm can be calculated using the formula C = πd. Substituting 43 for d, the exact circumference in terms of pi is 43π cm.
Explanation:The circumference of a circle is determined by the formula C = πd, where C is the circumference, d is the diameter of the circle, and π (Pi) is a mathematical constant whose approximate value is 3.14. If we plug the given diameter of 43 cm into the formula, we get C = π * 43. Thus, the exact circumference in terms of pi is 43π cm.

What is the value of x and y?
The 2 angles on the left need to equal 180:
3y +5 + 85 = 180
Combine like terms:
3y+90 = 180
Subtract 90 from each side:
3y = 90
Divide both sides by 3:
y = 90 /3
y = 30
Now solve the equation with y:
3(30) +5 = 90+5 = 95
Now the two equations also need to equal 180:
95 + 2x +1 = 180
Combine like terms:
2x + 96 = 180
Subtract 96 from each side:
2x = 84
Divide both sides by 2:
x = 84 /2
x = 42
X = 42, y = 30

Prove that the sum of the length of the diagonals of a quadrilateral is less than the perimeter, but greater than the half of the perimeter of this quadrilateral.
and
Prove that the sum of the lengths of the three medians in a triangle is smaller than the perimeter of the triangle. (The statement is true for the altitudes as well.)
Answer: Consider a quadrilateral ABCD such that AC ans BD are the two diagonals of ABCD.
With reference to figure 1 .
In triangle ABC and triangle ADC ,by using triangle inequality we have
AB +BC > AC .......(1)
and AD + CD >AC......(2)
adding (1) and (2) we have
AB+ BC+CD+AD>2AC....(3)
Similarly we get for diagonal BD
AB+BC+CD+AD>2BD....(4)
Adding (3) and (4) we get
2(AB+BC+CD+AD)> 2(AC+BD)
⇒(AB+BC+CD+AD)> AC+BD where (AB+BC+CD+AD) = perimeter of quadrilateral.
Hence, the sum of the length of the diagonals of a quadrilateral is less than the perimeter.
Now 2 diagonal divides quadrilateral into 4 quadrilaterals
Therefore AO+OD>AD
OD+OC>CD
OC+OB>BC
And OA+OB>AB
Adding all these conclude that
2(AC+BD)>AB+BC+CD+AD
⇒AC+BD>1/2(AB+BC+CD+AD) where (AB+BC+CD+AD) = perimeter of quadrilateral.
Hence,the sum of the length of the diagonals is greater than the half of the perimeter of this quadrilateral.
Now consider a triangle ABC as given in figure (2)
As we now,the sum of two sides of a triangle is greater than twice the median bisecting the third side.
Therefore AB+BC>2BE
Similarly,
AB+AC>2AD
BC+AC>2CF
By adding all these we get ,
2(AB+BC+CA)>2(AD+CF)
⇒AB+BC+CA>AD+CF
Hence, the sum of the lengths of the three medians in a triangle is smaller than the perimeter of the triangle.

The total height of all three of Thumbelina’s sisters is 60 cm. If the heights of the three sisters are in the ratio 4:3:5, find the height of the shortest sister.
Answer: 15 cm
Step-by-step explanation:
Given : The total height of all three of Thumbelina’s sisters is 60 cm.
The heights of the three sisters are in the ratio 4:3:5 .
Let the heights of the three sisters are 4x , 3x and 5x.
According to the question , we have the following equation :-
[tex]4x+3x+5x=60\\\\\Rightarrow\ 12x=60\\\\\Rightarrow\ x=\dfrac{60}{12}=5[/tex]
Now, the height of the shortest sister will be :-
[tex]3x=3(5)=15\ cm[/tex]
Hence, the height of the shortest sister = 15 cm

Mr. Davies opened a new retail store. During the first week, 360 customers visited the store. During the second week, 300 customers visited the store. What is the percentage change of the number of customers that visited the store in the first week to the number of customers that visited the store in the second week?
the answer is 16.7 because you need to do 60/360
The answer is 16.67%
Explanation:
Number of customers who visited in the first week = 360
Number of customers who visited in the second week = 300
Number of customers decreased in the second week =
