Result: 4m

Detailed explanation:

Important note: midpoints split a line into equal halves.

To find the length of SA;

We observe the larger triangle QRS, which includes

Two midpoints:

A located on line QS, QA = 4m;

and B on line RS where RB = 3m

Based on the midpoint definition:

QS = QA + AS

where QA = AS

QS = 2QA = 2AS

Hence,

QA = QS

4m = 4m

A national survey of 50,000 sixth graders asked if they know what they would like to do when they get older. Suppose you ask 350
AnnZ [12381]

You surveyed 350 students, out of which 182 were unsure.

The calculation gives: 182/350 = 0.52, indicating that 52% of the students were uncertain.

Now, apply this percentage to the national survey total:

50,000 x 0.52 = 26,000

The final result is 26,000 students who wouldn't know.

A pair of events are observed to have coordinates (0s,0m) and (50.0s,9.00×109m) in a frame s. what is the proper time interval δ
zzz [12365]
To determine the time interval δt, we must subtract the starting time from the ending time. In this scenario, the first value in the coordinates signifies time:

δt=50 - 0
δt= 50s

The time interval is 50s.

PIT_PIT [12445]

Answer:

8

Step-by-step explanation:

The task is to evaluate:

0.1m + 8 - 12n

When m=30, n=\frac{1}{4}

By substituting these values into the expression, we have:

0.1m+8-12n=0.1(30)+8-12(\frac{1}{4})\\=3+8-\frac{12}{4}\\=3+8-3\\=8
