Answer:

1500^2-800^2=1268.85

A=1268.85

1500+800=2300

2300-1268.85=1031.15

B=1031.15

Answer:

a) 1700 meters

b) 600 meters

Step-by-step explanation:

a) use pythagorean theorm to calculate the distance between the two boat ramps, since it is the hypotenuse of a right triangle.

1500^2+800^2

2250000+640000=2890000

square root of 2890000=1700.

The distance from boat ramp a to boat ramp b is 1700 meters.

b) to find the distance by road, you just add the two legs of the triangle.

1500+8=2300

the difference means you have to subtract the distance by canoe from the distance by road.

2300-1700=600

It is 600 meters farther to travel by road from ramp a to ramp b than to canoe between the two ramps.

Mr .Baker has baked some muffins. If he packs them in boxes of 4, he will have 3 left over. If he packs them in boxes of 5, he w

Answer:

$\boxed{43}$

Step-by-step explanation:

I think the easiest way to solve this problem is by brute force: trial and error.

We must find numbers that when divided by

4 leave 3 (4n + 3)
5 leave 3 (5n + 3)
6 leave 1 (6n + 1)

Here is a list of multiples of the integer n that satisfy the three conditions. $\begin{array}{c|ccc}\mathbf{n} & \mathbf{4n+ 3} & \mathbf{5n + 3} & \mathbf{6n + 1}\\1 & 7 & 8 & 7\\2 & 11 & 13 & 13\\3 & 15 & 18 & 19\\4 & 19 & 23 & 25\\5 & 23 & 28 & 31\\6 & 27 & 33 & 37\\7 & 31 & 38 & \mathbf{43}\\8 & 35 & \mathbf{43} & 49\\9 & 39 & 48 & 55\\10 & \mathbf{43} & 53 & 61\\\end{array}\\\text{The only number that is common to all three lists is $\mathbf{43}$.}\\\text{The smallest possible number of muffins Mr. Baker could have baked is $\boxed{\mathbf{43}}$.}$

Check:

$43 \div 4 = 10R3\\43 \div5 = 8R3\\43 \div 6 = 7R1$

OK .

Can someone help me please.

The first fraction is 7/10.
The second bag has the same probability as the top so just copy the fractions into the boxes.
To calculate the probability of the same colour being chosen you follow these steps.
P(RR) = 3/10 x 4/9 = 12/90
P(GG) = 7/10 x 5/9 = 35/90
Then add the two fractions.
12/90 + 35/90 = 47/90
The last box is 47/90.
