What is the degree?

Answer:

I havn't gotten c and d yet, but:

a) They are similar because of the Angle Angle Theorem

b) JN=4ft

Answer:

Yes

Step-by-step explanation:

You can use the perpendicular bisector theorem, because the bisecting line is intersecting at a right angle, which means it is actually perpendicular. Along with IJ and IH being congruent (equal)

Answer:

Stamp collected in June = 33

Step-by-step explanation:

Total stamp = 94

Stamp collected in April = 27

Stamp collected in May = 34

Stamp collected in June = x

Total stamp = April stamp + May stamp + June stamp

94 = 27 + 34 + x

94 = 61 + x

x = 94 - 61

x = 33

Stamp collected in June = 33

Answer:

We can determine from their equations whether two lines are parallel by comparing their slopes. If the slopes are the same and the y-intercepts are different, the lines are parallel. If the slopes are different, the lines are not parallel. Unlike parallel lines, perpendicular lines do intersect

Answer:

The answer to this equation is 3 3/16

Step-by-step explanation:

the area is 254.34 sq. ft.

Answer:

254.34 ft²

Step-by-step explanation:

diameter = 18 feet

radius = 18/2 = 9 feet

Area = pi x r²

= pi x 9²

= pi x 81

= 254.34 ft²

9514 1404 393

Answer:

  9 square units

Step-by-step explanation:

Pick's theorem is a useful relationship in circumstances like these. It tells you the area is ...

  A = i + b/2 - 1

where i is the number of interior points (8), and b is the number of points on the border (4).

The area of this figure is ...

  A = 8 + 4/2 -1 = 9

The area of the polygon is 9 square units.

_____

You can also get there by realizing the bounding rectangle is 4 units square. From that, corner triangles are cut. CW from upper left, those triangles have (base, height) dimensions of (3, 2), (1, 3), (3, 1), and (1, 2). So, the total of their areas is (1/2)(6 +3 + 3 +2) = 7 square units. The shaded area is then 16-7 = 9 square units, same as above.

Answer:

i dont know the system of equations since i only calculated it until i got the right answer but sara did 28 laps and mike did 14

Answer:

(x + 1)² + (y + 1)² = (√6)²

Step-by-step explanation:

Group the x- and y- terms together:

9x^2 + 18x + 9y^2 + 9y = 36

Factor out the coefficient 9:

x^2 + 2x + y^2 + y = 4

Complete the square of x^2 + 2x and then do the same for y^2 + 2y:

x^2 + 2x + 1 - 1 + y^2 + 2y + 1 - 1 = 4

Rewrite x^2 + 2x + 1 as the square of the binomial x + 1:

(x + 1)^2 + (y + 1)^2 - 2 = 4

Collect the constant terms on the right side:

(x + 1)^2 + (y + 1)^2 = 6

Rewrite 6 as (√6)^2:

(x + 1)² + (y + 1)² = (√6)² is the equation in standard form (x - h)² + (y - k)² = r²

Completing the square is done as follows:  x^2 + 2x

Start with x^2 + 2x

1.  Take half of the coefficient of x, which results in 2/2, or 1

2.  Square this result and add it to, and subtract it from x^2 + 2x

     x^2 + 2x + 1 - 1

3.  Rewrite the first three terms as the square of a binomial:  

     x^2 + 2x + 1 - 1 = (x + 1)² - 1.

Do the same for y² + 2y.

Answer: (x−3)(x+7)

Step-by-step explanation:

=(x+−3)(x+7)

=(x)(x)+(x)(7)+(−3)(x)+(−3)(7)

=x^2+7x−3x−21

=x^2+4x−21

Answer:

A. X^2+4x-21

Step-by-step explanation:

(x−3)(x+7)

=(x+−3)(x+7)

=(x)(x)+(x)(7)+(−3)(x)+(−3)(7)

=x2+7x−3x−21

=x2+4x−21

Answer:

That it's confusing to you is understandable, these problems are confusing, They take a bunch of real world things and put it into abstract concepts. The graph of the line is just that, an idea of how math represents the cost of the milk.

Step-by-step explanation:

the graph you are given is a straight line, not all graphs are straight lines, but b/c it's a straight line we get to "categorize" it as linear.  linear graphs are nice to work with,  as compared to curvey  ones.  aka  non-linear. There are a few famous formulas that go along with linear graphs.  Remember graphs are just representations of info in a way that we can use math to understand that real thing in abstract ways.  

the problem asks what is the slope of the line.  Think of the idea of a mountain slope here,  when we look at the graph.. and move over it like we would read,  from left to right, the graph moves up hill.. or positive,  so this graph is a positive slope graph.  now we just need to figure out a way to say that with numbers.  

often times slope is represented with the variable 'm' .  why 'm' you ask?  it's just a convention, it's not important which letter you use to represent slope but by convention we use 'm'   There is a formula for slope that goes like this,

m = (y2-y1) / (x2-x1)

we can use that to find the slope of this line, but we already know it's positive just by quickly looking at the graph.

the x's and y's in the formula are the x and y points of some exact point on the graph that we can find just by looking at the graph. :)  yes we get to make our own points.  P1  and P2  ( point 1  and point 2)

somebody has already made two nice black dots, on your graph for you, let's use those two black dots, you don't have to, but those do look convenient.  :)

using those two black dots and going from left to right.. I see the 1st point as P1 = (x1,y1) =( 2,10)  and the second point as P2 = (x2,y2) = (4,20)

then plug those into the above fomula

m = (20-10) / (4-2)

m = 10 / 2

m = 5

yep,  it's positive and steep up , that the answer to (a)

for (b)

we just need the formula called the point slope

y = mx + b

since we know m

y = 5x + b

for use b = 0

so just

y = 5x

now plug in x= 1/2, for the 1/2 gallon of milk

y = 5(1/2)

y = 2/5  

that's (b)  :)

Answer:

4 years

Step-by-step explanation:

Given data

Principal P=$5000

Rate r= 7.5%

Final amount A=$6500

The expression for the simple interest is

A=P(1+rt)

Substitute

6500=5000(1+0.075*t)

6500=5000+375t

6500-5000=375t

1500=375t

t= 1500/375

t= 4 years

Hence, the time is 4 years

DOES ANYONE KNOW THE ANSWER

Answer:

2

Step-by-step explanation:

when x is 2 y = 0.

lets start with writing the function's equation;

it has a slope of 2 so 2x + k = y

given in the question when x = -3, y = -10

so k = -4

y = 2x - 4, 0 = 2x-4 then x = 2
