Answer:

If it is a rectangular prism (this formula only works with that 3d shape, the answer is 2016 cm²

Step-by-step explanation:

SA=2(hl+hw+lw)

SA=2(18×19+18×18+18×19)

Sa=2(342+324+342)

sa=2(1008)

Find the unknown side of a rectangle solid. V=30 cm3, H=3 cm, W=5 cm

Alex17521 [72]

V = 30cm³
H = 3cm
W = 5cm
L = ?

V = H × W × L

therefore:
3 × 5 × L = 30
15L = 30
L = 30 : 15
<u>L = 2 (cm)</u>

A bank offers two interest plans Plan A gives you 6% interest compounded annually Plan B gives you 13% annual simple interest yo

xxTIMURxx [149]

Plan A gives you 6% interest compounded annually so after 4 years

$2000 becomes $2000*(1.06)^4 = $2524.95

Plan B gives you 13% annual simple interest so after 4 years

$2000 becomes $2000*(1+0.13*4) = $3040

so Plan B earns more

suppose you deposit $2,475 in a savings account that earns 6.25% simple interest per year. How much simple interest would be ear

Nikolay [14]

$116.02 interest will be earned in 9 months

Step-by-step explanation:

The formula for simple interest is given by:

$I = Prt$

Here

P is the initial amount

r is the interest

t is the time measured in years

Given

P = $2475

r = 6.25% = $\frac{6.25}{100} = 0.0625$

t = 9 months

Converting time into year by dividing by 12

$t = \frac{9}{12}\ years = 0.75\ year$

Putting the values in the formula

$I = 2475 * 0.0625 * 0.75\\I = 116.0156$

Rounding off to nearest hundredth

I = $116.02

Hence,

$116.02 interest will be earned in 9 months
