The normal price of a bicycle is £120
In a sale, there is 1/5 off the normal price of the bicycle.
Work out the price of the bicycle sale?
Answer:
76
Step-by-step explanation:
100% = 120
1/5 of 100% = 20%
20% = 120÷100×20
= 24
100-24= 76

shopkeeper sells tins of the same dog food in packs of four or packs of six.
Packs of four tins cost £1. Packs of six tins cost £1.20
Which is the best value for money?
You must show your working.
Answer:
Pack of 6
Step-by-step explanation:
Pack of 4 = £1
Packs of 6 = £1.20
Price per unit of each pack:
Pack of 4 ;
Unit price : cost / units
Unit price = £1 / 4 = £0.25
Pack of 6 ;
Unit price : cost / units
Unit price = £1.20 / 6 = £0.20
Pack of 6 is the best value for money as it has a lower unit price
What is the domain. How do I find it?
Answer:
All real numbers
Step-by-step explanation:
Here, we want to get the domain
The domain refers to the possible x values of the function
As we can see, the plot extends thoroughout the entirety of the graph
This extends from positive infinity to negative infinity
This means that the domain is all real

Five students each wrote an expression to represent the perimeter of the given rectangle. Terrell wrote this correct expression: (2x + 2x) + (5x + 5x) + (1 + 1). Circle the name of the student who wrote an incorrect expression. Explain why the expression is incorrect. Anya: 2x + 2x + 5x + 1 + 5x + 1 Katrin: 2(5x + 1) + 2x Luis 2(2x) + 2(5x + 1) Steve: 1 + 1 + x(2 + 2 + 5 + 5)
Answer:
Luis wrote an incorrect expression.
Step-by-step explanation:
As per Terrell, the correct expression is (2x+2x) + (5x+5x) + (1+1) which is equal to 12x + 2
For you who got incorrect answer, the answer if you simplified it must be 12x + 2. Let's check:
Anya 2x+2x+5x+1+5x+1 =
12x + 2 [CORRECT]
Katrin 2(5x+1) + 2x
10x+2+2x
12x + 2 [CORRECT]
Luis 2(2x) + 2(5x+1)
4x+10x+2
14x + 2 [INCORRECT]
Steve 1+1+ x(2+2+5+5)
2+ x(12)
12x + 2 [CORRECT]
Factor the quadratic 27x2-3
(x2 is X squared) please help.
Answer:
3(3x-1)(3x+1)
Step-by-step explanation:
27x²-3
You can factor out a 3
3(9x²-1)
Now we can use the difference of perfect squares formula
x²-y²=(x+y)(x-y) which means that 9x²-1=
(3x-1)(3x+1)
put it all together and get
3(3x-1)(3x+1)

(Equivalent Expressions) Which expression is equivalent to 3 + 2x + 6y + 6x + 2 – 2y?
Does the table represent an exponential function? Explain.
A. Yes, the x-values decrease by a constant amount and the y-values are multiplied by a constant amount.
B. No, the x- and y-values show a quadratic relationship only.
C. Yes, the x-values increase by a constant amount and the y-values are multiplied by a constant amount.
D. Yes, the y-values increase by a constant amount and the x-values are multiplied by a constant amount.
Answer:
No, because as the x-values are increasing by a constant amount, the y-values are not being multiplied by a constant amount.
Step-by-step explanation:
We have a set of ordered pairs of the form (x, y)
If a function is exponential then the ratio between the consecutive values of y, is always equal to a constant.
This means that:
\frac{y_2}{y_1}=\frac{y_3}{y_2}=\frac{y_4}{y_3}=by1y2=y2y3=y3y4=b
This is: y_2=by_1y2=by1
Now we have this set of points {(-1, -5), (0, -3), (1, -1), (2, 1)}
Observe that:
\begin{gathered}\frac{y_2}{y_1}=\frac{-3}{-5}=\frac{3}{5}\\\\\frac{y_3}{y_2}=\frac{-1}{-3}=\frac{1}{3}\\\\\frac{3}{5}\neq \frac{1}{3}\end{gathered}y1y2=−5−3=53y2y3=−3−1=3153=31
Then the values of y are not multiplied by a constant amount "b"
The solution to 5 - 3x > 35 is either x > -10 or -10 > x. Which soultion is correct? Explain how you know.
Answer:
x < - 10
Step-by-step explanation:
5 - 3x > 35
-3x > 35 - 5
-3x > 30
Divide both sides by 3
-x > 10
Divide both sides by - 1
x < - 10
The inequality sign will change due to the negative sign.

solve the simultaneous Equation
3/x- 4/y= 1/3
Answer:
a simultaneous equation is a set of equations. you need at least another equation.
Answer:
Step-by-step explanation:
Let's solve for x.
3x−4y= 1/ 3
Step 1: Add 4y to both sides.
3x−4y+4y= 1/ 3 +4y
3x=4y+ 1/ 3
Step 2: Divide both sides by 3.
3x/ 3 = 4y+ 1/ 3
3 x= 4/ 3 y+ 1/ 9
Answer:
x= 4/ 3 y+ 1/ 9
Let's solve for y.
3x−4y= 1/ 3
Step 1: Add -3x to both sides.
3x−4y+−3x= 1/ 3 +−3x
−4y=−3x+ 1/ 3
Step 2: Divide both sides by -4.
−4y/ −4 = −3x+ 1/ 3
−4 y= 3/ 4 x+ −1/ 12
Answer:
y= 3/ 4 x+ −1/ 12

A paperweight in the shape of a rectangular prism is shown: A right rectangular prism is shown with length 10 cm, width 4 cm, and height 4 cm. If a cross section of the paperweight is cut diagonal to the base, which shape describes the cross section?
Answer:
Square
Step-by-step explanation:
CHECK THE ATTACHMENT FOR THE FIQURE OF THE QUESTION
✓We were given the dimension of the rectangular prism as 10cm × 4cm × 4cm,
✓The cross section of the paperweight can be cut into half to it's base. Then the new dimension will be 4cm × 4cm which is a quadrilateral.
✓ Then width= 4cm, and height=4 cm are of the same values, hence the shape it forms is a SQUARE. and also the their angles is 90° each.
Find the volume of a cylinder with a height of 6 cm and a radius of 3 cm.

Answer: 1/14, 2/28.
Step-by-step explanation:
2/7 x 0.25 =
Convert 0.25 into a fraction.
0.25 = 1/4.
Multiply the numerators together and then multiply the denominators with each other.
1/4 x 2/7 = 2/28.
Therefore, the answer is 2/28, but it can also be simplified to 1/14. So the answer is the first one, or 1/14.
Answer:
1/14 or A
Step-by-step explanation:
0.25 as a fraction is 1/4
1/4 x 2/7 = 2/28, simplify to become 1/14, and there is your answer

do i add 40 + 45? Or multiply
Answer:
you add 40+45
Step-by-step explanation:
40+45=85
then you subtract 180 - 85 = 95
then divide x into 95 that will give you x=95
When placed near a second charge, a 60-μC charge experiences a force of 0.30 N. What is the electric field strength at the location of the 60-μC charge? What is the strength of the electric field at the location of the test charge?
Answer:
[tex]E=5000N/C[/tex]
Step-by-step explanation:
From the question we are told that
Charge [tex]q= 60 \mu C[/tex]
Force [tex]F_=0.30N[/tex]
Generally the equation for electric field strength is mathematically given as
[tex]E=F/q[/tex]
[tex]E=\frac{0.30}{60*10^-^6}[/tex]
Therefore
[tex]E=5000N/C[/tex]
