Answer:
£2088
or
US$ 2,536.48 dollars (2021)
Step-by-step explanation:
4% of 1800 = 72
72 x 4 = 288
1800 + 288 = 2088
He has £2088 at the bank after 4 year
Answer:
sinA(cosA+sinA)*cosA
Step-by-step explanation:
(sinA(2cosA+sinA-cosA))/secA
sinA(cosA+sinA)/secA
sinA(cosA+sinA)*cosA
Let L be the length
Let w be the width
Let p be the perimeter
L+w+L+w=p
L=w+20
3L+2w+3L+2w=240
Sub the first equation in for L in the second equation and solve for w
3(w+20)+2w+3(w+20)+2w=240
3w+60+2w+3w+60+2w=240
10w+120=240
10w=240-120
10w=120
W=120/10
W=12
Sub w into the first equation and solve for L
L=w+20
L=12+20
L=32
Hope this helps!
Answer:
35
Step-by-step explanation:
Make equations, l = w+5 and 2l + 2w = 150
Substitute w+5 into 2l + 2w = 150
Simplify to get 4w + 10 = 150
Subtract 10 from both sides to get 4w = 140
Divide both sides by 4 and you get 35 as width
345 in Standard Form is 3.45 x 10^2
This is because when in standard form the decimal should move to the right 2 times.
