<u>Answer:</u>
Cost of sand = £150
Cost of bricks = £157.5
Cost of cement = £134
Total cost = £441.50
<u>Step-by-step explanation:</u>
We are given that:
2 tonnes of sand is for £75.00 per tonne,
20 bags of cement are for £6.70 per bag,
350 bricks at 45p each,
So, 2 tonnes of sand at £75.00 per tonne = 2 * £75.00 = £150.00
20 bags of cement at £6.70 per bag = 20 * £6.70 = £134.00
350 bricks at 45p each = 350 * £0.45 = £157.50
Therefore, the total cost of all the materials = £150 + £134 + £157.5 = £441.50
Answer:
x=-17
Step-by-step explanation:
subtract 6 from each side and simplify and you'll get -17
X equals one. Hope this helps!
A and e are congruent so e is 105 since h and e make a line they will add up to 180
180=105+h
H= 75
If the triangles are similar then
8~y and 6~9 divide 9 by 6 to get the scale factor this is how much the triangle enlarges by or shrinks by
9/6= 1.5 now that you know the scale factor you can find y y/8=1.5
Y= 12
