A 1,300 kg car moving at 20 m/s and a 900 kg car moving at 15 m/a in precisely opposite directions crash head on. If we consider this event to be a perfectly inelastic collision, what is the speed of the cars after the impact?
Answer:
17.96m/s
Step-by-step explanation:
Based on law of conservation of momentum;
m1u1 +m2u2 =(m1+m2)v
v is the velocities of the car after impact
Substitute the given values
1300(20)+900(15) = (1300+900)v
26000 + 13500 = 2200v
39500 = 2200v
v = 39500/2200
v = 17.96m/s
Hence the speed of the cars after impact is 17.96m/s

Q1Skew lines are two lines that do not intersect and are not parallel.
AB and HG are parallel, BC is intersecting lineBG is skew line with CDCorrect option is C. BG
Q2Corresponding parts are congruent in congruent figures
∠H ≅ ∠F4x + 5 = 1054x = 100x = 25Q3Parallel line have same slopes

y = -3x + 7The only line with same slope of -3 is the last one:
3x + y = 10 ⇒ y = -3x + 10Correct option is D
B-30.45=95.28 what is the answer
Answer:
[tex]B = 125.73[/tex]
Step-by-step explanation:
Step 1: Add 30.45 to both sides
[tex]B - 30.45=95.28[/tex]
[tex]B +(- 30.45 + 30.45)=(95.28 + 30.45)[/tex]
[tex]B = 125.73[/tex]
Answer: [tex]B = 125.73[/tex]

In the x-values, there is a repeating 8.
Tell whether the angles are adjacent or vertical. Then find the value of x.
Answer:
Adjacent angles. x = 55
Step-by-step explanation:
Adjacent angles are angles that are right next to each other, sharing one side.
Since that is a right angle (90º):
X + 35 = 90
X + (35-35) = 90 - 35
X = 55
Hope this helps! Have a great day!
Answer:
Adjacent, X= 55
Step-by-step explanation:
90-35= 55

.The measures of the angles of a triangle are in the extended ratio 6: 1: 5. What is the measure of the largest angle?
9514 1404 393
Answer:
90°
Step-by-step explanation:
The largest angle is 6 of the 6+1+5 = 12 ratio units, so is 6/12 = 1/2 of the total number of degrees in a triangle.
The largest angle is 1/2(180°) = 90°.
A designer jacket was purchased for $140. Since it was purchased, the price has decreased by 18%. What is the price now?
Answer:

The ratio of cakes to cookies in the bakery was 3:5. If there were 90 cakes, how many cookies were in the bakery?
plz help
Answer:
150 cookies
Step-by-step explanation:
Using the ratio as an equation we can divide 90 by 3 to find the common multiple used to simplify this equation into a more usable ratio.
3 : 5 90 : 5x (x is the common multiple)
90 / 3 = 30, so x is 30
Then we multiply both sides of the original ratio by the common multiple to get our answer.
3 : 5 is equal to 90 : 150
what is the solution to the system of equations? please help im struggling really bad ):
Answer:
[tex] - 11 \frac{1}{2} [/tex]
Step-by-step explanation:
8x + 5y = 7
4x - 5y = 11
If you all it all up we have
8x + 4x +5y - 5y = 18
12x=18
x=18/12=1.5=3/2 = 1 whole number 1 over 2(1 1/2)
subtituting the value of x into equation 1(8x + 5y = 7)
8(1.5) + 5y = 7
5y=7-12
5y = -5
y=-5/5
y= -1
Marley walked around 2 rectangular parks. One measures 54 feet by 38 feet and the other measures 32 feet by 22 feet. How far did she walk?
Answer:
Step-by-step explanation:
Perimeter of Park 1 = 2*(54+38)
= 2 * 92
=184 feet
Perimeter of park 2 = 2*(32+ 22)
= 2 * 54
= 108 feet
Total distance = Perimeter of park 1 + perimeter of park 2
= 184 + 108
= 292
