Ms. Murray has a collection of 25 dimes and nickels. How many nickels does Ms. Murray have if she has a total of $2.30?

Olenka [21]

Four nickels,
because 1 dime=10¢ and so 21 x .10 = 2.10 and 1 nickel=5¢ so .05 x 4 = .20

2.10 + .20 = 2.30

I’m not sure if the explaining made sense but it’s 4 nickels :)

Solve to find missing length

shutvik [7]

Answer:

$m = 4\sqrt 3\\n = 6$

Step-by-step explanation:

$\tan \: 60 \degree = \frac{n}{2 \sqrt{3} } \\ \\ \sqrt{3} = \frac{n}{2 \sqrt{3} } \\ \\ n = \sqrt{3} \times 2 \sqrt{3} \\ \\ n = 2 \times 3 \\ \\ \huge \red { \boxed{ n = 6}} \\ \\ \cos \: 60 \degree = \frac{2 \sqrt{3} }{m} \\ \\ \frac{1}{2} = \frac{2 \sqrt{3} }{m} \\ \\ m = 2 \times 2 \sqrt{3} \\ \\ \huge \purple{ \boxed{ m = 4\sqrt{3} }}$

A group of tourists went downstream a river and are supposed to return in 3 hours. How far can the tourists travel down the rive

Olenka [21]

D=vt

So they will travel downstream and upstream the same distance. Downstream they will travel:

d=(2+18)t1

Upstream they will travel:

u=(18-2)t2

Since d=u we can say:

20t1=16t2

We are told the trip lasts 3 hours so t1+t2=3, t2=3-t1, using this in the equation above we have:

20t1=16(3-t1)

20t1=48-16t1

36t1=48

t1=4/3 hours, and from earlier we saw that d=20t1 so:

d=20*4/3

d=80/3 miles

d=26 2/3 miles.
