Well, It depends. It is either the mathematical term for 100% - 50%, or 6e*Ehq8deh.  So, It is either 1389D9238 or c793-sk2.  So try plotting the database point. Hope this helps :)

PLZ HELP ANSWER AND EXPLAIN. (photo) #8

The picture shown is a unfolded rectangular prism.

The formula to find the surface area of a rectangular prism is:

A = 2(WL+HL+HW)

(W = width, L = Length, H= Height)

So we would need to determine the Height, Length, and Width first, and then plug them into the formula and solve for the area.

In this case:
The height is: 4 cm 
The length is: 10.5 cm
The width is: 6.4 cm

Now that we have determined the height, length, and width, we simply plug them into the formula I showed earlier. 

In this case the answer would be 269.6.

D. 269.6

Colin invests £2350 into a savings account. The bank gives 4.2% compound
marin [14]

Answer:

Answer:

£3692

Step-by-step explanation:

A = p(1 + r/n)^nt

Where,

A = future value

P = principal = £2350

r = interest rate = 4.2% = 0.042

n = number of periods = 1(annual)

t = time = 4 years

A = p(1 + r/n)^nt

= 2350(1 + 0.042/1)^1*4

= 2350(1 + 0.042)^4

= 2350(1.042)^4

= 2350(1.5789)

= 2770.42

A = £2770.42

Total years = 10

Remaining years = 10 – 4

= 6 years

Remaining 6 years

P = £2770.42

r = 4.9% = 0.049

n = 1

t = 6

A = p(1 + r/n)^nt

= 2770.42(1 + 0.049/1)^1*6

= 2770.42(1 + 0.049)^6

= 2770.42(1.049)^6

= 2770.42(1.3325)

= 3691.59

A = £3691.59

Approximately £3692

Thank you!
