Answer:
Beatrice's age is 34
Step-by-step explanation:
Beatruce = B
Andrew = B+2
Chris= B-3
B+(B+2) +(B-3 )= 67-B
3B-1 = 67-B
2B -1 = 67
2B= 68
B = 34
Beatrice is 34
Andrew is 36 (34+2)
Chris is 31 (34-3)
36+31 = 67
Answer:
Step-by-step explanation:
To solve this, we can imagine a line drawn directly down from the point (10,4) to the x-axis. This would make a right triangle with length 10 and height 4.
is equal to the length of adjacent leg to the angle divided by the length of the hypotenuse of the triangle. From the picture, we can see the adjacent leg is 10.
We can use Pythagorean's Theorem to find the hypotenuse (let 
represent the length of the hypotenuse):
Thus, we know the adjacent is 10, and the hypotenuse is 
. This means .

Answer:
they are asking which claims are true vs false
Step-by-step explanation:
I totally get not wanting to bother our teachers again,... (that is why we're here)
m (AB = 20
m<ABD = 140
m (AD = 60
I think they want to know which ones (based on the "graph") are true,...
Answer:
-24
Step-by-step explanation:
So in short this is what it means:
-4×-2×-3
So to work it out this is what you do:
Deal with the first two numbers; -4 × -2=8
It becomes an eight without a negative because when multiplying numbers with the same signs(positive or negative) the answer is always a positive number thus the answer becomes 8.
Then 8×-3=-24
This is because when multiplying a negative and positive numbers the answer is always a negative numbers thus -24.
So automatically the answer is -24.

Answer:
Option A= 250
Step-by-step explanation:
Coterminal angles are angles in standard positions having thesame terminal .
Coterminal angles are always negative and positive.
For example:
The coterminal angle of 30° is-
30 - 360 = -330
30 + 360 = 390
Therefore, -330 and 390 are coterminal.
So, to the question:
The angles between 0 -360 coterminal to -110 is 250.
Prove:
250 - 360 = -110
250 + 360 = 610
Option A is correct
