Answer:

10/11

Step-by-step explanation:

35 stringed , 5 string and brass, 10 brass, 5 play neither string nor brass

P (A or B ) = students that play string or brass / total number of students = 35+5+10/ 35+5+10+5 = 50/55 = 10/11

Describe the relationship between the values of the given digit. The 4s in 44,000
Juli2301 [7.4K]

Answer:

  one of them has a value that is ten times the value of the other one

Step-by-step explanation:

The most-significant 4 has a value of 40,000.

The least-significant 4 has a value of 4,000.

The most-significant 4 has a value that is 40,000/4,000 = 10 times that of the least-significant 4.

_____

The basis of a place-value number system is that the value of a digit is multiplied by the value of the base when the digit is placed one more place to the left in the number. That is, the digit in the 5th place to the left of the decimal point will have a value that is 10 times the value of the same digit in the 4th place to the left of the decimal point.

What are the endpoint coordinates for the mid segment of △PQR that is parallel to PQ?
diamong [38]

Answer:

So the end points of the mid segment are:

S(-3.5,0.5)

T(-1,-0.5)

Step-by-step explanation:

First of all we need to list the co-ordinates of the points of the triangle shown.

P\rightarrow(-3,3)

Q\rightarrow(2,1)

R\rightarrow(-4,-2)

We need to find mid segment of the triangle which is parallel to segment PQ. This would mean we need to find midpoints of segment PR and QR and then join the points to get mid segment.

Midpoint Formula:

(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})

Midpoint of PR:

S((\frac{-3+(-4)}{2},\frac{3+(-2)}{2})\\\\(\frac{-3-4}{2},\frac{3-2}{2})\\\\(\frac{-7}{2},\frac{1}{2} )

S(-3.5,0.5)

Midpoint of QR:

T(\frac{2+(-4)}{2},\frac{1+(-2)}{2})\\\\(\frac{2-4}{2},\frac{1-2}{2} )\\\\(\frac{-2}{2},\frac{-1}{2}

T(-1,-0.5)

So the end points of the mid segment are:

S(-3.5,0.5)

T(-1,-0.5)

By mid segment theorem we know that the line joining midpoints of two sides of a triangle is parallel to the 3rd side.

∴ We know ST is parallel to PQ
