Ed buys a box of eggs costing £2.80, two packs of bacon for £2.40 each and two tins of baked beans. He pays with a £10 note and gets 80p change. How much does a tin of beans cost in pounds, £?

Answers

Answer 1

Answer:

£0.8

Step-by-step explanation:

egg = 2.80

Bacon = 2 * 2.40 = 4.80

Baked beans = 2 tins

Amount issued = 10

Change obtained = 80p = 0.8

Let cost per baked beans = x

Hence,

2.80 + 4.80 + 2x = 10 - 0.8

7.60 + 2x = 9.20

2x = 9.20 - 7.60

2x = 1.6

x = 1.6 / 2

x = 0.8

Hence, a tin of baked beans cost £0.8

Answer 2

Answer:

£0.80

Step-by-step explanation:

egg = 2.80

Bacon = 2 * 2.40 = 4.80

Baked beans = 2 tins

Amount issued = 10

Change obtained = 80p = 0.8

Let cost per baked beans = x

lol

2.80 + 4.80 + 2x = 10 - 0.8

7.60 + 2x = 9.20

2x = 9.20 - 7.60

2x = 1.6

x = 1.60 / 2

x = 0.80

YES WE GOT IT, a tin of baked beans cost £0.80

a sphere has a volume of 905cm. what is the radius of the sphere rounded to the nearest whole number ?

Answers

Answer:

r = 6

Step-by-step explanation:

The value of radius of the sphere rounded to the nearest whole number is,

⇒ r = 6 cm

We have to given that,

Volume of a sphere = 905 cm

Since, We know that,

Volume of sphere = 4/3 (πr³)

Where, 'r' is radius of sphere.

Now, Substitute the given value, we get;

⇒ 905 = 4/3 (πr³)

⇒ 905 × 3 = 4 × 3.14 × r³

⇒ 2,715 = 12.56 × r³

⇒ r³ = 216.16

⇒ r = ∛216.16

⇒ r = 6 cm

Thus, The value of radius of the sphere rounded to the nearest whole number is,

⇒ r = 6 cm

Answers

Answer:

explaination

Step-by-step explanation:

# carry on learning

The solution is, A. y = 5x, the equation represents the relationship between x and y.

What is equation?

An equation can be stated as a mathematical statement that is made up of two expressions connected by an equal sign. In its normal form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.

here, we have,

Direct proportion equation:

y = kx, where k is the coefficient of proportionality

We have:

x = 3 and y = 15

Using the equation to find the value of k:

15 = 3k

k = 15/3

k = 5

The equation of the line:

y = 5x

Correct choice is A

Hence, The solution is, A. y = 5x, the equation represents the relationship between x and y.

The sum of 22 and 33 by using distributive property will be; 55.

How to find Greatest common factor?

The greatest common factor, as the name implies, is the greatest among all common factors among the quantities given.

We can factorize the quantities in the smallest relative factors possible (one level of factors over which all quantities can form themselves), and collect as many common factors as we could.

Factors:

22: 1 ,2, 11, 22

33: 1, 3, 11, 33

Both the numbers have a GCF of 11. Then by removing 11 from both numbers you end up with:

22 = 2 x 11

33 = 3 x 11

Now replace the values on the right of the equals sign into the original equation then;

(2 x 11) + ( 3 x 11)

The distributive property allows us to remove the common values and rewrite them;

11(2 + 3)

11(5)

The sum of 22 and 33 by using distributive property will be; 55.

A rectangular dining room has an area of 20 square meters. It's perimeter is 18 meters. What are the dimensions of the dining room?

Answers

Answer:

The dimensions are:

Length = 5m and Width = 4m

Length = 4m and Width = 5m

Step-by-step explanation:

A rectangular dining room has an area of 20 square meters. It's perimeter is 18 meters. What are the dimensions of the dining room?

Area of a rectangle = Length × Width

= LW = 20 m²

Perimeter of a rectangle =

2L + 2W = 18 m

Hence:

LW = 20...... Equation 1

L = 20/W

2L + 2W = 18 ...... Equation 2

We substitute

20/W for L in Equation 2

2(20/W) + 2W = 18

40/W + 2W = 18

Multiply through by W

40 + 2W² = 18W

2W² - 18W + 40 = 0

2W² - 10W - 8W + 40 = 0

(2W - 8 )(W - 5) = 0

2W - 8 = 0

2W = 8 , W = 8/2 = 4m

W - 5 = 0

W = 5m

W = 4m or 5 m

Solving for L

When W = 5 m

L = 20/W

L = 20/5

L = 4m

When W = 4m

L = 20/W

L = 20/4

L = 5m

Therefore, the dimensions are:

Length = 5m and Width = 4m

Length = 4m and Width = 5m
