A. 20H + 58 is your answer

The car is already 20 miles north of the city at time zero.  If the car continues north at the rate 58 mph, for h hours, the additional distance is then (58 mph)h.  Thus, at any zero or positive time h, the car's distance "d" from the city is 
d=20 miles + (58 mph)*h.

3. A square metal plate has a density of 10.2 g/cm3 and weighs 2.193 kg.
MakcuM [25]

Answer:

215 cm³

8.6 cm

Step-by-step explanation:

given,

density = 10.2 g/cm³

mass = 2.193 kg = 2193g

a. Volume = mass / density

=2193 / 10.2

= 215 cm³

b. given that base area = 25cm²

volume = base area x thickness

thickness = volume / base area

= 215 / 25

= 8.6 cm

10x + 7y=1<br> -5x-7y=24
nikitadnepr [17]
Okay, so since both y values share the same number, let's add both equations so the y values cancel out leaving us to solve for x.

10x+(-5x)=5x

7y+(-7y)=0

1+24=25

Now we have 5x=25

divide both sides by 5 and we have x=5

Now that we know x=5, we can plug it into one of the problems to find y.

Let's do 10(5) +7y=1   

50+7y=1  subtract 5 and we get 7y=-49

divide -7 from both sides and we get y=-7

so there you have it x=5 and y=-7

if £2000 is placed into a bank account the pays 3percent compound interest per year, how much will be in the account after 2 yea
Nastasia [14]

Answer:

£2,120.00

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 3%/100 = 0.03 per year.

Solving our equation:

A = 2000(1 + (0.03 × 2)) = 2120

A = $2,120.00

The total amount accrued, principal plus interest, from simple interest on a principal of £2,000.00 at a rate of 3% per year for 2 years is £2,120.00.
