Estimate the total weight of two million pounds worth of two pence coins in kilograms. A two pence coin weighs 7.1g.
Answer: 710,000 kg
Step-by-step explanation:
There are 100 pence in one pound.
The number of two pence coins in 1 pound is therefore:
= 100 / 2
= 50 coins
In 2 million pounds therefore, there will be:
= 50 * 2,000,000
= 100,000,000 two pence coins
If one coin weighs 7.1g, weight is:
= 100,000,000 * 7.1
= 710,000,000 g
A kg is 1,000 grams so the weight in kg is:
= 710,000,000/1,000
= 710,000 kg

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

Pick the answer that best fits the description
Answer:
Cannot be determined
Step-by-step explanation:
You cannot assume the function travels down infinitely, because the function is not given to you. The graph could go up down left or right for all you know, you just cannot see it.
? divided by 1/3= 9/10
Answer:
3/10
Step-by-step explanation:
because if you use a calculator that answer would be 0.9 which is 9/10 as a decimal and if u did it yourself then you would do 1/3 x 9/10 and you would get 9/30 which is 3/10 if u simplify it

Step-by-step explanation:
Use the Distributive Property to solve the equation.
- 8(x + 7) = 16
Apply the Distributive Property and simplify.
- 8(x + 7) = 16
- 8x + = 16
Answer:
x= - 9
Step-by-step explanation:
- 8(x +7) = 16-8x - 56 = 16 -8x = 16 + 56-8x = 72x = 72 ÷ (-8) x = -9Hey there!
Use the Distributive Property and simplify:
-8(x+7)=16
-8x-56=16
Notice we write -8 right next to x.
Add 56 to both sides:
-8x=16+56
-8x=72
Divide both sides by -8:
x=-9
Hope everything is clear.

I need help on this homework
Answer:
(4,0) and (2,0)
Step-by-step explanation:
For an x-intercept, y=0, so now we have:
(x-4)(x-2)=0
Anything multiplied by 0 is 0, so (x-4)=0 and/or (x-2)=0
(x-4)=0
x=4
(x-2)=0
x=2
The x-intercept co-ordinates are: (4,0), (2,0)
Answer:
x-intercepts are (4,0) and (2,0)

What is the greatest surface area of a rectangular solid that can be built from 16 identical unit cubes?
Answer and explanation:
The surface area of a solid is the sum of the areas of all faces of the solid. The surface area of a cube is calculated using the formula 6a² since a cube has 6 faces in total likewise a cuboid.
We can say the rectangular solid is a cuboid and to find the surface area of the cuboid we add up the surface area of all 16 cubes
Surface area is therefore 16×6a²

Maria is a florist in a small boutique. If Maria paid her supplier 8.50$/dozen for roses and sold them for 19.95$, what was the mark up in percent?
Answer:
The markup percentage was 135%.
Step-by-step explanation:
In order to find the markup percent, you have to take the sales price minus the cost and divide that by the cost. Then, you have to multiply by 100 to establish the markup percentage:
markup percentage=((19.95-8.50)/8.50)*100
markup percentage=(11.45/8.50)*100
markup percentage=135%
According to this, the answer is that the markup percentage was 135%.
Karen bought 8 pounds of fruit to make 3 equal-sized fruit salads. What is the weight of each fruit salad? 2 pounds 223 2 2 3 pounds 3 pounds 313 3 1 3 pounds
Answer: 2²/₃ pounds
Step-by-step explanation:
There are 8 pounds of fruit.
These are to be used to make 3 equal sized fruit salad.
The weights of each fruit salad will therefore be:
= Pounds of fruit/ Number of fruit salads
= 8 / 3
= 2²/₃ pounds

1) 8 bananas cost £4
Work out the cost of 5 bananas.
Work out the size of angle x.
Not drawn accurately
132°
X Х
54°
Answer:
x = 84
Step-by-step explanation:
The sum of the angles around a point = 360°
sum the given angles and equate to 360
x + 132 + 54 + 90 = 360
x + 276 = 360 ( subtract 276 from both sides )
x = 84
Answer:
x = 84°
Step-by-step explanation:
→ Recall the fact that angles around a point add up to 360°
360 - (90 + 54 + 132 ) = x
→ Simplify
360 - 276 = x
→ Simplify again
84 = x ∴ x = 84°
