Answer:
-4,-1
Step-by-step explanation:
So how I did it is, I made a mintale picture of it in my head. Then, I "counted" how much space I had to go for the next point. And that's how I got the answer of -4,-1.
1 hour 42 minutes 1 hour 32 minutes+1 hour 38 minuts+1 hour 30 minutes
Answer:
382
Step-by-step explanation:
Just add all of them and 1 hour equals 60 mins
First, lets add the hours.
1 hour + 1 hour + 1 hour = 3 hours
Now, let's add the minutes,
42 minutes + 32 minutes + 38 minutes + 30 minutes = 142 minutes
1 hour = 60 minutes
How many grouped 60's are there in 142? There are 2 full 60s in 142 minutes.
2 60s = 120 minutes
Add 2 hours, but subtract 120 minutes.
142 minutes - 120 minutes = 22 minutes
So, the final answer is 5 hours and 22 minutes.

Answer: C
Step-by-step explanation:
A binary star system consists of two stars of masses m1 and m2. The stars, which gravitationally attract each other, revolve around the center of mass of the system. The star with mass mi has a centripetal acceleration of magnitude a1.
Find a2, the magnitude of the centripetal acceleration of the star with mass m2 Express the acceleration in terms of quantities given in the problem introduction.
Answer:
a₂ = G(m₁ + m₂)/(R - √[G(m₁ + m₂)/a₁])²
Step-by-step explanation:
Since the gravitation force of attraction of the center of mass on m₁ equals the centripetal force, then
G(m₁ + m₂)m₁/R₁ = m₁a₁ where (m₁ + m₂) = total mass of the system and R₁ = distance of m₁ from the center of mass
So, G(m₁ + m₂)m₁/R₁² = m₁a₁
G(m₁ + m₂)m₁/m₁a₁ = R₁²
R₁² = G(m₁ + m₂)/a₁
R₁ = √[G(m₁ + m₂)/a₁]
The distance of m₂ from the center of mass is thus R₂ = R - R₁ = R - √[G(m₁ + m₂)/a₁] where R is the distance between the two stars.
Also, the gravitation force of attraction of the center of mass on m₂ equals the centripetal force, then
G(m₁ + m₂)m₂/R₂ = m₂a₂ where (m₁ + m₂) = total mass of the system and R₂ = distance of m₂ from the center of mass
So, G(m₁ + m₂)m₂/R₂² = m₂a₂
G(m₁ + m₂)m₂/m₂R₂² = a₂
a₂ = G(m₁ + m₂)/R₂²
Substituting R₂ into the equation, we have
a₂ = G(m₁ + m₂)/(R - √[G(m₁ + m₂)/a₁])²

What is a trapezoid?An open, flat object with four straight sides and one set of parallel sides is referred to as a trapezoid or trapezium. A trapezium's non-parallel sides are referred to as the legs, while its parallel sides are referred to as the bases.
Given:
The parallel sides of the trapezium are 9 cm and 6 cm respectively
and the distance between these sides is 15 cm.
We know that,
Area of a trapezium= 1/2 × Sum of parallel sides × distance between them.
The area of a trapezium = 1/2 x 15 x 15
The area of a trapezium = 112.5 square centimeters.
Therefore, the area is 112.5 square centimeters.

Little's law can be applied to any part of the store, such as a particular department or the checkout lines. The store owner determines that, during business hours, approximately 84 shoppers per hour make a purchase and each of these shoppers spend an average of 5 minutes in the checkout line. At any time during business hours, about how many shoppers, on average, are waiting in the checkout line to make a purchase at the Good Deals Store?
Number of shoppers per hour (during business hours) = 84
Time spent by each shopper (average) = 5 mins
Now,→ 60 mins (1 hour) = 84 shoppers
→ 60 = 84
→ 84/60
→ 1.4
→ 1.4 × 5 = 7
→ 7 shoppers on an average, are waiting in the checkout line to purchase at the "Good Deals store"

What is the answer to 7x-7=12x+13
Answer:
x = − 4
Step-by-step explanation:
Answer:
x = -4
Step-by-step explanation:
First, add 7 to both sides:
7x - 7= 12x + 13
7x = 12x + 20
Subtract 12x from both sides:
-5x = 20
Divide each side by -5:
x = -4
So, the answer is x = -4
