Answer:
two nickles and six dimes
Step-by-step explanation:
x= dimes
y=nickles
.10x+.05y=0.70
plug in random whole numbers that add up to eight 8 for example you can do x=5 and y=3
that gives you .5+.15=.65
keep doing that until you get x=6 and y=2
It is important because it is more easy to do your work of math
Answer:
Four 10s and seven 5s
Step-by-step explanation:
If you start with one 10, you have to have four 5s. After that you add one of each until you reach 75
The diagonal of the rectangle is equivalent to finding the length of the hypotenuse of a right triangle with sides 3 and 4. Using the Pythagorean Theorem:
32+42=hypotenuse2
25=hypotenuse2
The two ways to find the ratio of the length is to turn the inches into feet or the feet into inches
So the answer can be solved like this:
1/36ft to 1/4ft which is 9:1 (blueprint size to actual size)
or
1/3in to 3in which is also 9:1 (blueprint size to actual size)
