Answer:
A. t=13 B. K= 23 C. t= 1 3/8
Step-by-step explanation:
A. 2t-30m=20
30 x 1/5= 6
2t-6+6=20+6
2t/2=26/2
t=13
B. 14+m=2k
14+12=2k
14+12=46
46/2=23
k=23
C. 1/8r+t=1
1/8 x (-3)= -3/8
1 - (-3/8)= 1 3/8
t= 1 3/8
Hope it helps!

Given;

Required; To determine where 1 banana went if 29 bananas are accounted for.
Step 2
Here is the break down; the balance should be like this;

Hence, there is no extra 1 banana, The monkeys spent 27 bananas of which the bellboy took 2 bananas and 25 bananas went to the room, and 3 bananas where returned to them. A total of 30 bananas
Answer:
yes, this is a triangle. It is a right triangle
Step-by-step explanation:
The three angles of a triangle add to 180 degrees
27+90+63 = 180
180=180
This is true so it is a triangle.
Because one of the angles is 90 degrees, it is a special type of triangle called a right triangle.
Answer:
The top 30% is defined with a score greater than or equal to 431.44 so she will not be admitted (D)
Step-by-step explanation:
Mean m = 400
Standard deviation S = 60
Firstly, we have to determine the cut off mark,
Since Only students who score in the top 30% are accepted, the cut off mark can be determined from 70% of the mark.
P(cut off mark = X) = Z[( X -m)/S) <x]
=¢(X-400/60) = 0.7
From Normal distribution table,
X-400/60 = 0.524
X = 431.44
Therefore, the cut off mark is 431.44
Since Amy scores 425 on the test.
Therefore, The top 30% is defined with a score greater than or equal to 431.44 so she will not be admitted (D)
