A blueprint for a house has a scale factor = 10. A wall in the blueprint is 8 in. What is the length of the actual wall?
oksian1 [2.3K]

Answer: 6.67 feet (check to see if you made a typo)

Step-by-step explanation:

if the scale factor is ten than we multiply 8 by 10

8 * 10 = 80

important to remember this is 80 INCHES not 80 FEET

to convert 80 inches into feet, we divide by 12 because there are 12 inches in a foot

80/12 = 6.67 feet

check to make sure that the first option is actually 6.67 inches because it would make more sense for it to be in feet

Day                                                  Number of Ants

1                                                                       10

11                                                                      20

21                                                                     40

31                                                                     80

41                                                                     160

<em>51                                                                    320-----------------given</em>

<em>61                                                                    640------------------given</em>

<em>71                                                                    1280----------------given</em>

81                                                                   2560

91                                                                    5120

Using the given values for number of ants and the number of days, you can notice the trend for values of days and number of ants.After every ten days, number of ants doubles.Using this information, you can navigate backwards up to day 1 and forward up to day 91

Carter invested $16,000 in an account paying an interest rate of 5.6% compounded monthly. Assuming no deposits or withdrawals ar
jenyasd209 [6]

Answer:

11 years.

Step-by-step explanation:

Given that Carter invested $ 16,000 in an account paying an interest rate of 5.6% compounded monthly, to determine, assuming no deposits or withdrawals are made, how long would it take, to the nearest year, for the value of the account to reach $ 29,600, the following calculation must be performed:

16,000 x (1 + 0.056 / 12) ^ Yx12 = 29,600

Y = 11

16,000 x 1.4666 ^ 132 = X

29,581.70 = X

Thus, rounded to the nearest year, it would take 11 years for the account to reach $ 29,600.
