1) 728.41m of 20th day for Daniella.
Didn't find n, sorry.
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.
Answer:
472 in²
Step-by-step explanation:
This net is made up of 3 identical rectangles and 2 identical triangles.
Area of a rectangle = width x length
Area of a triangle = 1/2 x base x height
<u>Rectangle</u>
- width = 8 in
- length = 19 in
<u>Triangle</u>
<u>Surface Area</u>
SA = 3(8 x 19) + 2(0.5 x 8 x 2)
⇒ SA = 456 + 16
⇒ SA = 472 in²
<h3>f(x) is equal to 4.5 when x = 1/2</h3>
<em><u>Solution:</u></em>
Given that,
We have to find f(x) when x = 1/2
We can solve by substituting x = 1/2 in given function
Thus f(x) is equal to 4.5 when x = 1/2
