Which best completes the following sentence? triangles are congruent if they have the same

Answer: n/2, n/2+1

Step-by-step explanation:

Consecutive numbers are always 1 more than the previous (n, n+1, n+2, n+...), and their sums are (like) n+n+1 or 2n+1 (n is the first number).

So in this situation (x is the first number);

n+1=x+x+1

n=x+x, n=2x

n/2=x

Meaning that the first number is n/2, and the second (n/2)+1 or just n/2+1.

Answer:

1600cm³

Step-by-step explanation:

Volume of a cylinder = πr²h

area of a circle = πr²

area of base circle = 200cm²

h = 8

200 * 8

= 1600cm³

Answer:

Volume is 1600 cm ^3

Step-by-step explanation:

V= Base area x Height

h= 8 cm

B.A.= 200 cm^2

Step-by-step explanation:

A(3,7) B(-2,1) C(2,0) D(5,-6)

180 rotation around origin = (-x,-y)

A(3,7) - A(-3,-7)

B(-2,1) - B(2,-1)

C(2,0) - C(-2,0)

D(5,-6) - D (-5,6)

Answer:

A(-3, -7)  B(2,-1)  C(-2,0)  D(-5,6)

Step-by-step explanation:

A(3,7) B(-2,1) C(2,0) D(5,-6)

180 rotation around the origin would equal (-x,-y)

A(3,7) - A(-3,-7)

B(-2,1) - B(2,-1)

C(2,0) - C(-2,0)

D(5,-6) - D (-5,6)

Answer:

SA. = 62.8 +87.92= 150.72

Step-by-step explanation:

surface area of cone without base = pi*r*s = 3.14 * 2* 10 = 62.8

Surface area of cylinder without base = 2*pi*r*h + pi*r*r

                                                               = 2* 3.14 * 2 * 6 + 3.14*2*2

                                                               = 75.36 + 12.56 = 87.92

SA. = 62.8 +87.92= 150.72

The required surface area of the solid is 150.72.

Given
slant length of cone = 10
length of cylinder = 6  
Common radius = 2

Surface area is defined as the area of the surface that are uncovered.

Surface area of cone = π x r xs
= 3.14 x 2 x 10
= 62.82

Surface area of cylinder  = 2 x π x r x h + π x r²
= 2 x 3.14 x 2 x 6 + 3.14 x 2 x 2
= 87.9
The required surface area of solid= surface area of cone + surface area of cylinder
= 62.80 + 87.9
= 150.72

Thus, the required surface area of the solid is 150.72.

Answer:

t= 30/7 or 4 and 2/7 (depend on if the answer calls for improper or mixed number form. they're the same answer written in different forms.)

Step-by-step explanation:

First, you must simplify. 2/3 minus 1/5 equals 7/15. So, the simplified expression is 7/15t=2. Then you have to divide each side by 7/15 to separate t from its coefficient. 2 divided by 7/15 is equal to 2 times 15/7 becausedivision of fractions is done by multiplying by the reciprocal. 2 times 15/7 equals 30/7, or 4 and 2/7 when simplified.

Answer:

460 kilometers

Step-by-step explanation:

The 262,400 solar cells cover around 27,000 square feet (2,500 m2) of space. 240 kilowatts of electricity can be generated from these solar arrays.which is an acre of solar panels and enough to power 10 average- sized homes with 110 kilowatts of power. The ISS orbits between 370 and 460 kilometers (230–286 miles) above Earth's surface.

Answer:

The total area of the top surface of all 16 solar panels should be 153,600 feet because the total area of one solar panel is 9,600 feet so since i need the total area of 16 i just multiply the total area of one solar panel with the amount of solar panels that i was given.

x = 30

Step-by-step explanation:

The figures are similar, thus the ratios of corresponding sides are equal, that is

[tex]\frac{x}{18}[/tex] = [tex]\frac{45}{27}[/tex] ( cross- multiply )

27x = 810 ( divide both sides by 27 )

x = 30

The answer is at least 360 degrees.

Step-by-step explanation: A circle can't have more that a 360 degrees!

The correct option is B.

A mathematical phrase, rule, or law that establishes the link between an independent variable and a dependent variable (the dependent variable).

As per the given data:

We are given 2 graphs in the diagram.

We are also given the equation of f(x) with its graph.

Furthermore, we have to find out the equation of g(x) from its graph.

We can see that the blue graph is just the red graph with its axis moved 2 units to the right.

We can find the horizontal transformation by:

g(x) = f(x - h)

Where h is the number of units we shift (to the right).

Since we shifted two units to the right, h = 2.

So, our new function will be:

g(x) = (x - 2)²

The correct option is B.

Hence, The correct option is B.

2)y=-2x+13

3) Parallel lines have same slope, different y intercept and perpendicular lines have opposite reciprocal slopes.

Step-by-step explanation:

Answer:

Below in bold.

Step-by-step explanation:

Y = mx + b is the slope-intercept form of a straight line where  m = the slope of the line and b is the y-intercept.

Parallel lines have the same slope so the equation of a line parallel to

y = 1/2x + 13 could be  y =1/2x + 10 as they have the same slope of 1/2.

Equations which are perpendicular:

If the slope of one  is m then the slope of the perpendicular equation is -1/m.

So for y = 1/2 x + 13  an equation perpendicular could be y=  -(1 / 1/2) + 13

= y = -2x +  13
