There are a few questions that I need help with. any answers would be a great.

1. 11 cm sq

2. $48

3. 2,697,986

4. (can't see the whole thing)

Step-by-step explanation:

1st one

I just tested out all the possibilities and that is the smallest it can get

2nd one

First, we add up 1/4 and 1/3

1/4 = 3/12

1/3 = 4/12

3/12+4/12 is 7/12 this is how much money she spent in total

5/12 is remaining which we know is $20 so if we find what 1/12 is we can multiply to find the original. 20/5=4. 1/12 = 4 now we do 4*12 which is 48 so she had $48 originally.

3rd one

This one the wording is weird, so they are just asking what minus 2 700 000 is 2014. We can just do 2,700,000-2014 which is 2,697,986

4th one

I cant see the whole problem, ill be glad to help but I cant see it rn.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
