Answer:
34
Step-by-step explanation:
:)
Answer:
34
Step-by-step explanation:
Remember that the sum of the angles of a triangle is 180
And since two sides are congruent b = 73
So 180-(73+73) = 34
Which equation represents a circle that contains the point (-5, 3) and has a center at (-2, 1)? Distance formula: vaa -02 (x - 1)2 + ( + 2)2 = 25 (x + 2)2 + (-1)=5 O (* + 2) + (-1) - 25 (x-1) + ( + 2) = 5
Given:
The center of the circle = (-2,1).
Circle passes through the point (-5,3).
To find:
The equation of the circle.
Solution:
Radius is the distance between the center of the circle and any point on the circle. So, radius of the circle is the distance between the points (-2,1) and (-5,3).
[tex]Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
[tex]r=\sqrt{(-5-(-2))^2+(3-1)^2}[/tex]
[tex]r=\sqrt{(-5+2)^2+(2)^2}[/tex]
[tex]r=\sqrt{(-3)^2+(2)^2}[/tex]
On further simplification, we get
[tex]r=\sqrt{9+4}[/tex]
[tex]r=\sqrt{13}[/tex]
The standard form of a circle is:
[tex](x-h)^2+(y-k)^2=r^2[/tex]
Where, (h,k) is the center of the circle and r is the radius of the circle.
Substitute h=-2, k=1 and [tex]r=\sqrt{13}[/tex].
[tex](x-(-2))^2+(y-1)^2=(\sqrt{13})^2[/tex]
[tex](x+2)^2+(y-1)^2=13[/tex]
Therefore, the equation of the circle is [tex](x+2)^2+(y-1)^2=13[/tex].

The short sides of a rectangle are 2 inches. The long sides of the same rectangle are three less than an unknown number of inches.
If the area of the rectangle is 22 square inches, what is the value of the unknown number?
Given:
Short sides of a rectangle = 2 inches.
Area of the rectangle = 22 square inches.
The long sides of the same rectangle are three less than an unknown number of inches.
To find:
The unknown number.
Solution:
Let x be the unknown number. Then the longer side of the rectangle is (x-3) inches.
We know that the area of a rectangle is
[tex]A=length\times width[/tex]
The area of the rectangle is 22 square inches.
[tex]22=2(x-3)[/tex]
Divide both sides by 2.
[tex]11=x-3[/tex]
Add 3 on both sides.
[tex]11+3=x-3+3[/tex]
[tex]14=x[/tex]
Therefore, the value of the unknown number is 14.
Calculate the distance Katie rides her bike if she rides 7/10 mile each day for 9 days?
Answer:
6.3 miles
Step-by-step explanation:
7/10 = 0.7
0.7 x 9 = 6.3 miles after 9 days
The distance Katie rides her bike if she rides 7/10 mile each day for 9 days is 6.3 miles.
What is Distance ?Distance is the total movement of an object without any regard to direction.
We can define distance as to how much ground an object has covered despite its starting or ending point
Katie rides her bike 7/10 mile each day for 9 days
In 1 day she covers a distance of 0.7 mile
so in 9 days she will cover
=0.7 * 9
= 6.3 miles
Therefore the distance Katie rides her bike if she rides 7/10 mile each day for 9 days is 6.3 miles.

The average number of people who attended football games at a stadium increased from 8000 people in the year 2005 to 12500 people in the year 2012. By what percentage did the average number of people at the games increase from 2005 to 2012?
Answer: 43.75%
Step-by-step explanation:
The percentage change is given by:
= [Final value - initial value / Initial value] x 100
The percentage increase in the average number of people from 2005 to 2012 is 56.25%.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying it by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
We have,
The average number of people in 2005 = 8000.
The average number of people in 2012 = 12500.
The change in the average number of people from 2005 to 2012.
= 12500 - 8000
= 4500
The percentage change in the average number of people at the games from 2005 to 2012.
= [Change in the average number of people / Average number of people in 2005] x 100
= (4500 / 8000) x 100
= 450/8
= 56.25%
Thus,
The percentage increase in the average number of people from 2005 to 2012 is 56.25%.

if m<AFC= 150°, what is m<CFD
Answer:
30
Step-by-step explanation:
These are djacent angles ( two angles that have the same vertex, share a side, and do not overlap) The 2 angles form a linear pair The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.
If one angle is 150 then the other angle must be 30
150+30 = 180

The graph models the value of a vehicle over x years following its purchase for $25,000.
Which interpretation is correct?
(A) The asymptote indicates that the original value of the vehicle approached $25,000
(B) The point (40, 0) contains the x-intercept
(C) The line x=25,000 is an asymptote of the graph
(D)The line y=0 is an asymptote of the graph
Answer: it’s D. I took the test
The correct interpretation are,
The asymptote indicates that the original value of the vehicle approached $25,000
The line y=0 is an asymptote of the graph
Graph of function:From the given graph,
It is observed that graph is never intersect the x- axis. Therefore, x-axis will be the asymptote.
The equation of x- axis is y= 0.
Since at x= 0, the value of y = 25,000 , It means that the original value of the vehicle approached $25,000.
The x- intercept is the point where graph crosses the x-axis.

You and Mr. Fowles have decided to race each other at the Boston Marathon (26 miles long). Mr. Fowles runs at a steady 4.2 miles per hour. He knows your best time is 3 miles per hour so he gives you a 3 mile lead. When will he catch you? How far behind are you when Mr. Fowles finishes the race? How much longer will it take for you to finish?
Answer:
The answer is below
Step-by-step explanation:
Speed is the time rate of change of velocity, it is the ratio of distance to time.
Mr. Fowles runs at a steady 4.2 miles per hour. The time taken to cover 26 miles is:
speed = distance / time
time = distance / speed = 26 / 4.2 = 6.19 hour
I run at 3 miles per hour. I was given 3 mile lead, so the remaining distance is 23 miles (26 - 3). The time needed to complete the 23 miles is:
time = distance / speed = 23 / 3 = 7.67 hour
a) Let d be the distance Mr Fowles catches me. Hence:
time = (d + 3)/4.2; also time = d/3
(d + 3)/4.2 = d/3
3d + 9 = 4.2d
1.2d = 9
d = 7.5 miles
He would catch me at 10.5 (7.5 + 3) miles from the starting point.
b) Mr. fowles finishes after 6.19 hour. At that time, the distance is have covered is:
distance = 6.19 * 3 mi/hr = 18.57 mile
Distance behind = 23 mile - 18.57 = 4.43 mile
c) time longer = 7.67 hour - 6.19 hour = 1.48 hour
