If i read this correctly then the answer would be
57-12= 45
45/9= 5
The answer is 5
9514 1404 393
Answer:
a = 7
Step-by-step explanation:
The Pythagorean theorem tells you the value of 'a' is ...
a^2 = b^2 - c^2
a^2 = 25^2 -24^2 = 625 -576 = 49
a = √49 = 7
The length of side 'a' is 7 units.
Answer:
D) 5/8
Step-by-step explanation:
Since Susie has 5 books and 8 hair pins, you get 5:8 which can be transferred into a fraction of 5/8.
Answer:
We know that an isosceles triangle has 2 of its sides being equal
With R, being the midpoint of PS, we can say that
PR=RS
Noting that, with R as midpoint, we can conclude that RT is a straight line which divides angles TPR and TSR into 2 right angle triangles
Step-by-step explanation:
therefore angle at P is 45°. Angle at S also 45°
Therefore PT = TS
This is because T is 45 degrees as well as P which is also 45 degrees
angle in triangle PTS is 180 degrees
R is 90 degrees, P is 45 degrees and the whole of T is also 45 degrees(which has been split into 2)

Answer: 4/21
Step-by-step explanation:
Total number of tiles(possible outcomes) = 7
Number of green tiles(required outcomes) =2
Number of Blue tiles(required outcomes) = 4
Recall :
Probability (P) = Required outcome / total possible outcomes
First pick (without replacement) :
P(picking a green tile) = 2/7
Second pick :
Tiles left after first pick = 6
P(picking a blue tile) = 4/6 = 2/3
Compound probability :
P(picking a green tile) × p(picking a blue tile)
(2/7) × (2/3) = 4/21
