Tom is tiling a wall.
He needs to buy at least 100 tiles. The tiles are sold in large packs and small packs.
Large pack = 40 tiles £18
Small pack = 28 tiles £14
Special offer = 25% reduction when you buy 3 or more large packs.
Work out the cheapest cost for Tom to buy the packs of tiles he needs.
Answer £
Answers
Answer:
The correct answer is - £ 40.5 for 3 large packs.
Step-by-step explanation:
Given:
Large pack = 40 tiles £18
Small pack = 28 tiles £14
Special offer = 25% reduction when you buy 3 or more large packs.
Solution:
Following combinations are possible for tom to get the tiles he needs:
1. 3 large packs
40*3 = 120 tiles with 25% discount
cost = 18*3 - 0.25*18*3 = 40.5
2. 4 small packs
28*4 = 112 tiles
cost = 14*4 = 56
3. 2 large packs and 1 small pack
40*2 + 28 = 108 tiles
cost = 18*2 + 14 = 50
4. 1 large pack and 3 small packs
40 + 28*3 = 124 tiles
cost = 18 + 14*3 = 60
Thus, the correct answer is - 1st case with three large packs.
R and S are two observation posts on the same horizontal ground as the foot P of a vertical tower PQ The tower is 18m due north of S and 24m east of R. The angle of elevation of Q from S is 35°.Calculate the height PQ.
Answers
Answer: [tex]12.6\ m[/tex]
Step-by-step explanation:
Given
Distance of Point S is 18 m from tower
Distance of point R is 24 m form tower
Suppose the height of tower PQ is h
angle of elevation of Q from S is [tex]35^{\circ}[/tex]
from the figure, we can write
[tex]\Rightarrow \tan 35^{\circ}=\dfrac{h}{18}\\\\\Rightarrow h=18\tan 35^{\circ}\\\Rightarrow h=12.60\ m[/tex]

60=70-h I can't seem to find my answer and it a bit hard
Answers
Answer:
10
Step-by-step explanation:
We need to solve the equation . The equation is z
→ 60 = 70 - h
Subtracting 70 both sides .→ 60 - 70 = 70 - h - 70
→ -10 = -h
Dividing both sides by -1 .→ -h/-1 = -10/-1
→ h = 10
• Hence the value of h is 10 .Farmer Brown grows corn on his 110 acre farm. The yield for his farm is 17,600 bushels of corn. Farmer Diaz grows wheat on his farm.

A.35
B.105
C.140
D.3850
Answers
Answer:
Difference of density per acre of wheat and corn = 105
Step-by-step explanation:
Given:
Yield in 110 acre farm = 17,600 Bushes of corn
Yield in 250 acre farm = 13,750 Bushes of wheat
Find:
Difference of density per acre of wheat and corn
Computation:
Yield per acres Bushes of corn = 17,600 / 110
Yield per acres Bushes of corn = 160
Yield per acres Bushes of wheat = 13,750 / 250
Yield per acres Bushes of wheat = 55
Difference of density per acre of wheat and corn = Yield per acres Bushes of corn - Yield per acres Bushes of wheat
Difference of density per acre of wheat and corn = 160 - 55
Difference of density per acre of wheat and corn = 105

A man travels in a taxi for 12.2 miles.
What is the cost of his journey?
Show your working
Answers
Answer:
£23.30
Step-by-step explanation:
First, find the cost from traveling 12.2 miles. Since the cost is £1.50 per mile, multiply 12.2 by 1.5:
12.2(1.5)
= 18.3
Add the standing charge to this:
18.3 + 5
= 23.3
So, the cost of his journey is £23.30
