Answer:

two consecutive numbers are 14 and -15

Step-by-step explanation:

let the number be x and x + 1.

x(x + 1) = 210

x^2 + x = 210

x^2 + x - 210 = 0

(x + 5) (x - 14) = 0

x = -15 and 14

Rachel invested $15,000 in a nine-year CD giving 8.5% interest, but needed to withdraw $4,000 after two years. If the CD's penal
drek231 [11]
Given:
Principal = 15,000
interest = 8.5%
term = 9 years

I = 15,000 * 8.5% * 9 years = 11,475
total amount after 9 years = 15,000 + 11,475 = 26, 475

Preterm after 2 years. wdl of 4,000. penalty is 6 months interest of 4,000

I = 4,000 * 8.5% * 6/12 = 170  amount of penalty
I = 15,000 * 8.5% * 2 years = 2,550 interest earned for 2 years

15,000 + 2,550 = 17,550
17,550 - 4,000 - 170 = 13,380 amount to be invested for another 7 years

I = 13,380 * 8.5% * 7 years = 7,961.10
total amount after 9 years with pretermination
 13,380 + 7,961.10 = 21,341.10

Waclaw needs to drive 478 miles on Oak Street and 434 miles on Pine Street to get to the nearest gas station.
Mekhanik [1.2K]

Answer:

1. can

2. less

3. 5

Step-by-step explanation:

To find out if Waclaw could make it to the gas station using 10 miles, we need to add the number of miles he has to go in order to reach his destination.

4\frac{7}{8}+4\frac{3}{4}  = 9\frac{5}{8}\\

9 5/8 is less than 10, so he can make it to the gas station.

We can also find out the answer without even adding the numbers together, because both values are less than five, and when that happens, the sum cannot be 10 or more, so Waclaw can make it to the gas station.
