Once the Bolsheviks seized control of Russia’s government Lenin began to negotiate an armistice with the Central Powers. Why were many Russians concerned with Lenin’s plan to end Russia’s participation in the war?
Answer:
I'm reading about it and mostly they're saying they were concerned with internal conflict within Russia. I'm not positive, it could be because of the loss of land, but it appears to be more politically motivated. uprisings with in the country. so my best guess would be none of the above

Line AB connects the ends of the horseshoe and passes through the stake at point (x,y). If the equation for line AB is x = 6, which of these might be the coordinates of the stake? Assume that all the points lie in a rectangular coordinate system.
https://portal.achieve3000.com/images/uploads/m910_teensatcamp09.gif
Answer:
(6,0), (6,1), (6,2) (6,3)...
Step-by-step explanation:
x = 6
This means that 6 is the x-intercept since this is the equation for a verticle line, this means that x remains in 6 and y is the only number that moves so the AB stake point could be any number where x is 6, it could even be (6,0),
(6,1) e.t.c.

Given the diagram below, find the height of the shorter tree.
16.2 m
7 m
13 m
19.7 m
Answer:
h = 13 m
Step-by-step explanation:
The triangles are similar, so the ratios of corresponding sides are equal, that is
[tex]\frac{h}{39}[/tex] = [tex]\frac{16}{48}[/tex] = [tex]\frac{1}{3}[/tex] ( cross- multiply )
3h = 39 ( divide noth sides by 3 )

The price of a visit to the dentist is $50. If the dentist fills any cavities, an additional charge of $100 per cavity
gets added to the bill.
If the dentist finds n cavities, what will the cost of the visit be?
Answer:
I believe the answer will be 50+100n dollars
Step-by-step explanation:
n is the number of cavities so however many cavities there is, it gets multiplied by 100, in this case, it is 100*n which is 100n. So your final cost would be 50+100n dollars.
What is the amount of interest that Sam will pay on his $5000 loan if his monthly payment for three years is 150
Answer:
Amount of interest pay by Sam = $400
Step-by-step explanation:
Given:
Amount of loan taken by Sam = $5,000
Monthly payment made by Sam = $150
Number of year payment made by Sam = 3 Year
Find:
Amount of interest pay by Sam
Computation:
Total amount pay by Sam in 3 year = Monthly payment made by Sam x 12 x 3
Total amount pay by Sam in 3 year = 150 x 12 x 3
Total amount pay by Sam in 3 year = $5,400
Amount of interest pay by Sam = Total amount pay by Sam in 3 year - Amount of loan taken by Sam
Amount of interest pay by Sam = $5,400 - $5,000
Amount of interest pay by Sam = $400
What is the equation of a circle with a center located at (-3, 4) and a diameter of 14?
Answer: (x + 3)^2 + (y - 4)^2 = 49
Step-by-step explanation:
The equation of a circle given the center and radius: (x - h)^2 + (y - k)^2 = r^2
Given: center (-3,4) ; h = -3 and k = 4
diameter = 14
To find the radius: divide the diameter by 2 = 14/2 = 7 = r
Center: (-3,4) and radius: 7
Equation of a circle: (x - h)^2 + (y - k) ^2 = r^2
Substitute h = -3, k = 4, r = 7
(x - (-3))^2 + (y - 4)^2 = 7^2
Answer:
Equation of the circle: (x + 3)^2 + (y - 4)^2 = 49
Write the equation for a circle with a center at (-7 , -4) and a radius of 2.
Answer:
(x + 7)² + (y + 4) ² = 2²
Step-by-step explanation:
Start with the standard equation of a circle with center at (h, k) and radius r:
(x - h)² + (y - k)² = r²
Here we are given that h = -7, k = -4 and r = 2, and so we obtain:
(x + 7)² + (y + 4) ² = 2²
Step-by-step explanation:
The answer is above, as well as the equation used to get to the answer.
