The most efficient way of finding the answer to this question is first reducing 10-24-26 and comparing it with the first 5 combinations for right-angled triangles:
First, reduce 10-24-26 by dividing it by the GCF (greatest common factor).
10-24-26 divided by its GCF, 2, is: 5-12-13
Now comparing it with the first 5 combinations for right-angled triangles:
1) 3-4-5
2) 5-12-13
3) 7-24-25
4) 8-15-17
5) 20-21-29
As you can see, number 2 is the same as our reduced example. Therefore, we know that 10-24-26 is a right triangle.
Hope this helps!
Answer:
A
Step-by-step explanation:
Since DE is parallel to AB and intersects the other 2 sides, it divides those sides proportionally, that is
=
Note that AD = 33 - 22 = 11
Substitute values into the ratio
= = ( cross- multiply )
2x = 16 ( divide both sides by 2 )
x = 8
To find y use similar triangles
Δ ABC is similar to Δ DEC, thus ratios of corresponding sides are equal
= , substitute values
= = ( cross- multiply )
3y = 36 ( divide both sides by 3 )
y = 12
Thus y = 12, x = 8 → A
Answer:
C. 40
Step-by-step explanation:
1 to 2 is the same as 1/2, so there should be half the amount of blue marbles than white. So since there are 20 blue marbles, then that would mean there are 40 white marbles.

Answer:
26.96 inches of fabrics per person
Step-by-step explanation:
Headband
Number of players = 32
Number of coaches = 2
Total people = 32 + 2 = 34
Total fabrics used for headband = 623.22 inches
Fabrics per person = Total fabrics used for headband / Total people
= 623.22/34
= 18.33 inches per person
Wristband
Number of players = 32
Total fabrics used for wristband = 276.16 inches
Fabrics per person = Total fabrics used for wristband / Number of players
= 276.16 / 32
= 8.63 inches per person
Total fabrics used for headband and wristband for each player = 18.33 inches + 8.63 inches
= 26.96 inches of fabrics per person
Subtract 1.65 by .75, which will give you 90 cents as the answer!
