2. Jacob Thomas had a deposit of two checks: $341.79 and $17.96;
Novosadov [1.4K]

Answer:

$938.66

Step-by-step explanation:

Cheque = $341.79 + $17.96 =$359.75

<u>Cash</u>

Paper Currency:

=(35 X $1)+(17 X $5)+(44 X $10)

= 35+85+440

=$560

Coins

=(54 X $0.25)+(36 X $0.10)+ (32 X $0.05) + (21 X $0.01)

=13.5+3.6+1.6+0.21

=$18.91

Total Cash Deposit = Paper Currency + Coins

=$560+18.91

=$578.91

Therefore, Jacob's Total Deposit

= Total Cheque Deposit+ Total Cash Deposit

=$359.75+578.91

=$938.66

A cone has a volume of 2560π cm cubed and a heigh of 30 cm.
Korolek [52]

Answer:

r = 16 cm

g = 34 cm

LA = 1708.16 cm^2

Step-by-step explanation:

We have that for the cone, the formula is as follows:

v = pi / 3 * r ^ 2 * h

the first thing they ask is to calculate the radius, therefore we solve for r

r ^ 2 = 3 * v / (pi * h)

replacing the volume and height, it remains:

r ^ 2 = 3 * 2560 * pi / (pi * 30)

r ^ 2 = 3 * 2560/30 = 256

r = 16

Now, to calculate the slant height, that is to say g, we can calculate it knowing the height and the radius:

g ^ 2 = r ^ 2 + h ^ 2

g ^ 2 = 16 ^ 2 + 30 ^ 2

g ^ 2 = 1156

g = 34

The lateral area of the cone is given by the following equation:

LA = pi * r * g

replacing

LA = 3.14 * 16 * 34

LA = 1708.16 cm ^ 2

the lateral area is 1708.16 cm ^ 2
