astra-53 [7]

Answer: C.186


Step-by-step explanation:

1. You know that he read 6 books when he was 6 years old and every year he doubled the number of books he read the previous year.

2. Let's call n the number of book he read each year and n_t the number of books he read between the ages of 6 and 10, then:

 - At 6 years old:

n=6

- At 7 years old:

n=6*2=12

- At 8 years old:

n=12*2=24

- At 9 years old:

n=24*2=48

- At 10 years old:

n=96

The total books he read between the ages of 6 and 10 is:

n_t=6+12+24+48+96\\n_t=186

A mother wants to invest ​$6000 for her​ children's education. She invests a portion of the money in a bank certificate of depos
mariarad [96]

Answer:

Money invested in CD account: $2000

Money Invested in Savings Bond: $4000

Step-by-step explanation:

Given

Total amount=$6000

Let  

x be the amount invested in CD at 4%

And

6000-x be the remaining amount invested in savings bond at 7%

So mathematically writing

0.04x+0.07(6000-x)=360

0.04x+420-0.07x=360

-0.03x+420=360

-0.03x=360-420

-0.03x= -60

x= -60/(-0.03)

x=$2000

So the amount invested in CD is $2000.

And the amount invested in savings bond is:

=6000-x

=6000-2000

=$4000  ..

Question 1. What will Amanda pay if she rents a truck and drives 45 miles and splits the total cost with two friends? Explain wi
BabaBlast [244]

Answer:

A) Amanda will pay $47.5

B) 0.5

C) $120

Step-by-step explanation:

A) From the graph given, at 45 miles, the total cost of rentage = $142.50

She now splits this cost with 2 of her friends. Thus each of them will pay;

Amount = 142.5/3 = $47.5

So,Amanda will pay $47.5

B) To find the slope, we will pick two points on the graph and use their respective coordinates to find the slope.

Coordinates we pick are;

(0, 120) and (50, 145)

Thus, slope; m = (y2 - y1)/(x2 - x1)

m = (145 - 120)/(50 - 0)

m = 25/50

m = 0.5

C) The equation for the graph will now be; y = mx + c

Where m is slope and c is y - intercept.

Thus;

y = 0.5x + 120

Coincidentally, c = 120 will be the fixed price of the truck while 0.5x will be the variable cost depending on how many miles are driven.

Thus renting for a day is simply the fixed cost of $120
