Packet of 12 pencils = p
Packet of 30 rulers = r
p = £2.15
r = £6.00
£35 = 4r + xp
£35 = 4(£6.00) + x(£2.15)
£35 = £24 + £2.15x
£11 = £2.15x
x = 5.12
Since she can buy 5.12 packets of pencils, it is equal to 5 packets of pencils.
Given:
uniforms in a package of 8.
127 people with 3 uniforms each.
127 x 3 = 381 uniforms
381 ÷ 8 = 47.625 ⇒ 48 packages
The store will need to order 48 packages of uniforms to fulfill the uniform requirement of 127 people. There will also be 3 uniforms left in excess of the 48 packages.
48 * 8 = 384
384 - 381 = 3 excess uniform
Answer: (-5)¹¹ of (-5)^11
Step-by-step explanation:
Since the base of the two exponents are teh same at -5, we can subtract the exponents.
5-(-6)=11
Now, we know that the new exponent will be 11, with the base staying the same.
The answer is B.
Explanation:
In scientific notation, a number must be put in an expression multiplied by ten to a given power. An example of this would be 3 x 10^2 because it is a form of saying 3 x 100. In B, 10 is accompanied by a degrees sign instead of a power. Therefore, this expression is not shown in scientific notation.
