1a) so for this problem, I took what they gave you, 637.5 and divided it by .75 and got 850
so .75 * 850 = the gallons, so just take the number of hours and multiply it by 850 to get your gallons
0.25 x 850 = 212.5
1.5 x 850 = 1,275
2.5 x 850 = 2,125
1b) the unit rate is 850
1c) 5.5 x 850 = 4,675 gallons
1d) So 850 gallons can be filled in an hour, you only need 100 gallons
850/100 = 17/2 (simplified)
17 gallons/hour 60 minutes
------------------------- x ---------------------
2 gallons 1 hour
the gallons cancel out and the hours cancel out which leaves us with:
17 x 60 = 1,020 / 2 = 510
510 minutes
2) I don't know how to do two sorry

Answer:
- JK slope: -1/3
- KL slope: 3
- JL slope: -7
- is
- two of the slopes have a product of -1
Step-by-step explanation:
The slope formula is useful.
m = (y2 -y1)/(x2 -x1)
__
JK slope = (1 -2)/(3 -1) = -1/3
KL slope = (-5-1)/(1-3) = -6/-2 = 3
JL slope = (-5-2)/(1-0) = -7
We observe that slopes (-1/3) and (3) have a product of -1, so those line segments are perpendicular. The triangle is a right triangle.
Answer:
3 x 5 divided by 1/3
45
Step-by-step explanation:
Answer:
Side MQ is similar to side MR.
- This is because since M is the mid point of QR, both MQ and MR are half of QR.
Angle MXQ and MYR are 90°
Sides QX and RY are similar.
- This is because angle X and Y are 90° and MQ and MR are equal.
∴ MQX is congruent to MRY.
