Answer:for the one with 16 is 28 and the one with 7 is 4
Step-by-step explanation:
Since none of these are like terms, none of these could be added together. All you need to do is to order these by alphabetical order. Therefore, the simplified form of this expression is an+bn+7a+7b
£1400
A reduction of 40% means that £840 is 60% of the original price
Divide £840 by 60 to find 1% then multiply by 100 to find original price
original price = £840 × = £1400
Answer:
When a wire is bent to form a circle then its length represents the circumference of the circle formed. Therefore in our case the circumference of the circle is 50 cm. we can use this to determine the radius of the circle and then determine the area. Circumference of a circle is given by \pi × diameter, (\pi = 3.142)
thus diameter will be given by 50 cm ÷ 3.142 = 15.9134 cm
the radius will be 15.9134 ÷2 = 7.9567 cm or ≈ 7.96 cm
The area of a circle is given by \pi × square of radius
Area = 3.142 × 7.96×7.96 = 199.0821 square cm
Thus the area of the circle formed is ≈ 199.08 square cm ( 2 decimal places)
