4= 4/1 as a fraction, and you must make 2 3/5 into a improper fraction, to do that you must multiply the denominator times the whole number and add the numerator so 5x2=10 and 10+3=13 so the numerator now turns into 13 and the denominator stays the same (5) so now you have 4/1 - 13/5 but you can’t still subtract that so find the least common denominator of 4/1 and 13/5 which is 5 so now we have 20/5 - 13/5 which equals 7/5 now you have your answer

Can someone help me with this please??

Answer:

z=20.8

x=16.97

y=12

Step-by-step explanation:

The triangle on the right is a 30,60,90 triangle, a special right triangle with simple rules to find the side lengths. sides A,B, and C where C is the hypotenuse (24 in your diagram). The short side A is= 1/2 of side C (12 in your diagram). The long side B is= side A*√3 (20.8 in your diagram).

The triangle on the left is another special right triangle called a 45,45,90. The rules for this triangle are C= A*√2, and B=A. Because of the rules in the 30,60,90 triangle, we know that side A is 12. This means that side B (y)=12. Side C (x)= 16.97.

Hope this helped! Sorry if my explanation is confusing, but the rules for special right triangles can be easily found online and then calculated :)

Three points lie on the same straight line. If each point can act as an endpoint, how many distinct line segments can be formed
lesantik [10]
Assume that the points are A, B, and C, B is between A and C, and note that a distinct line segment means that, at most, one point can intersect. This means that if we have AB and AC, AB has more than one point and AB is part of AC, so they are not two distinct lines. However, AB and BC are distinct due to that they only intersect at B. Our options to connect points are AB, AC, and BC. Since AC overlaps BC and AB, if AC is used, we have 1 as our answer. However, we can use AB and BC, increasing our limit to 2.


 Look at the picture for a visual (B is the black, and A and C can be interchangeable with the other points), and feel free to ask further questions!

. In April, it rained 1/4 of an inch on 15 different days. How many inches of rain fell
notka56 [123]

Answer:

3.75, or \frac{15}{4} inches of rain during the 15 days of April.

Step-by-step explanation:

All you have to do is add \frac{1}{4} 15 times to get that number.

\frac{1}{4} +\frac{1}{4} +\frac{1}{4} +\frac{1}{4} +\frac{1}{4} +\frac{1}{4} +\frac{1}{4} +\frac{1}{4} +\frac{1}{4} +\frac{1}{4} +\frac{1}{4} +\frac{1}{4} +\frac{1}{4} +\frac{1}{4} = 3.75

You can also do 15 times \frac{1}{4}, which will result in the same thing.
