Brainliest! 1. estimate the sum or difference. use the benchmarks 0, 1/2 and 1

a. 0

b. 1/2

c. 1

2. tom walked 1/5 of a mile on monday and 6/7 of a mile on tuesday. how far did he walk in all?

a. about 1/2 mile

b. about 1 mile

c. about 1 1/2 miles

d. about 2 miles.

3. tom read for 7/8 of an hour on monday and 2/8 of an hour on tuesday. how much longer did he read on monday than tuesday?

a. 1/2

b. 5/8

c. 3/4

d. 1 1/8

A) The sum or difference of the numbers is , option B

B)  The total distance cover by Tom is 1 miles

C)  The longer duration of Tom on Monday than Tuesday is hours , option B              

Step-by-step explanation:

Given as :

A) The given benchmarks as 0 , , 1

From the given number , the mid number is  

So, The sum of the number = 0 +  

I,e The sum of the number =  

And The difference of number = 1 -  

Or, The difference of number =  

Or, The difference of number =

Hence The sum or difference of the numbers is  Answer

B) The distance cover by Tom on Monday = miles

The distance cover by Tom on Tuesday = miles

So, The total distance cover = The distance cover on Monday + The distance cover on Tuesday

I.e  The total distance cover =   miles +   miles

Now, taking LCM

Or, The total distance cover =   miles

Or, The total distance cover =   miles

I.e The total distance cover =  1 miles

Hence The total distance cover by Tom is 1 miles Answer

C) The time period of Tom reading on Monday = hours

The time period of Tom reading on Tuesday = hours

The longer duration of Tom on Monday than Tuesday = x hours

So, x =   The time period of Tom reading on Monday -  The time period of Tom reading on Tuesday

I.e x = hours - hours

∴ x = hours

I,e x = hours

So, The longer duration of Tom on Monday than Tuesday = x =   hours

Hence  The longer duration of Tom on Monday than Tuesday is hours   . option B  Answer

answer: c, the green line

step-by-step explanation:

there is no black line, eliminate b.

simple interest implies periodic payments, but the red line shows no payments, eliminate d.

simple interest has equal payments. if paid say every day, the graph is about a straight line (actually a stairstep).

the yellow line is not straight, eliminate a.

check: the green line is straight, answer is c.

simple interest with positive interest rate gives a straight line sloping up to the right. green line:

g(t) = $100 + ($200-$100) ÷ (20 years) × (t years)

= $100 + (4%/year) × ($100)(t years)

incidentally, the yellow line curving upward represents continuously compounded interest

y = $100 × 2^(t years / (14 assuming the yellow line hits $200 at 14 years. 2^0 is 1, so y(0) = $100; 2^(14/14) is 2, so y(14) = $200.
