30. The table below shows the number of ants in an ant farm on differentdays. The number of ants doubles every ten days. MAFS.J.
Day
71
51
320
61
640
Number of Ants
1,280
a. How many ants were in the farm on Day 1?
b. How many ants will be in the farm on Day 91?

Answers

Answer:

a)10

b)5120

Step-by-step explanation:

Given that number of ants double after every ten days, form a table that shows numbe of ants from day 1 to day 91

Day                                                  Number of Ants

1                                                                       10

11                                                                      20

21                                                                     40

31                                                                     80

41                                                                     160

51                                                                    320-----------------given

61                                                                    640------------------given

71                                                                    1280----------------given

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

The sum of the measure of the interior angles of a polygon is 2160°. What polygon is it? 14-gon 12-gon 13-gon 15-gon

Answers

Answer:

It is a 14-gon.

Step-by-step explanation:

Sum of internal angles of an  n sided polygon =  180(n - 2) degrees.

2160 = 180(n - 2)

2160 = 180n - 360

`180n =  2520

n = 2520 / 180

= 14.

Answer:

12-gon

Ms. johnson is in charge of decorations for a party. She bought 6 bags of balloons. Each bag has 25 balloons. She fills all the balloons and puts 5 balloons in each bunch. How many bunches can she make?

Answers

the answer to your question is 30
Well first you have to do 25 × 6 which is 150. Then you have to do 150 ÷ 5 which  is 30. So the answer is 30 bunches. Hope this helped.

Approximate the real zeros of f(x)=2x^4-x^3+x-2 to the nearest tenth. a. , 1 c. 0, 1 b. , d. , 0 Please select the best answer from the choices provided

Answers

ANSWER

-1.0, 1.0

EXPLANATION

The given polynomial function is

f(x) = 2 {x}^(4) - {x}^(3) + x - 2

According to the Rational Roots Theorem, the possible roots of this function are;

\pm1,\pm (1)/(2)

We now use the Remainnder Theorem to obtain;

f(1) = 2 {(1)}^(4) - {(1)}^(3) + 1 - 2

f(1) = 2 - 1+ 1 - 2 = 0

f( - 1) = 2 {( - 1)}^(4) - {( - 1)}^(3) - 1 - 2

f( - 1) = 2 + 1 - 1 - 2 = 0

But;

f( (1)/(2) ) = - 1.5

f( - (1)/(2) ) = - 2.25

Since f(1)=0 and f(-1)=0, the real zeros to the nearest tenth are:

-1.0 and 1.0
