This is an exponential growth question, specifically population growth. We will use the following equation to help us solve this situation:
P(t) = a(1+r)t
P(t) = total population (??)
a = initial population = 260,000
r = growth factor (the percent as a decimal) = 0.055
1 + r = 1 + 0.055 = 1.055
t = time in years = 12
So, we can substitute all our information and solve:
P(12) = 260,000(1.055)12 = 494,313.95
Rounding to the nearest whole person, 494,314 people in 12 years.

A) CD is an altitude of ΔABC
B) AE is a median of ΔABC
C) AD is an altitude of ΔABC
D) AD is an median of ΔABC
Answer:
option B and Option C are correct since
AE divides BC into 2 equal parts so AE is Median of ∆ABC
AD makes a 90° Angle with BC Therefore AD is Altitude.
A football field measures 300 feet in length. It can also be expressed as approximately 5. 7 times 10 Superscript n miles. If there are 5,280 feet in 1 mile, which is the most reasonable value of n? Negative 3 Negative 2 2 3.
The most reasonable value of n n = -2.
We have given that the length of the football field = 300 feet
It can also be expressed as approximately [tex]5.7\times 10^{n}miles[/tex]
What is the value of one mile in feet?Also, 1 mile = 5280 feet....(1)
We have to find 1 feet so divide both side of equation (1)by by 5280 we get,
[tex]1feet=\frac{1}{5280}[/tex]
Now, for 300 feet is,
[tex]300feet=\frac{1}{5280}(300)[/tex]
[tex]300 feet=0.056818181=0.057miles[/tex]
In scientific notation we have,
[tex]300 feet=5.7\times 10^{-2}miles[/tex]
Therefore we get n = -2.

volume is 180 cubic inches.
What is the height of the box?
A. 12 inches
B. 15 inches
C. 18 inches
D. 10 inches
Answer:
A
Step-by-step explanation:
Volume of a rectangular prism = l*b *h
Where base area = l*b
Volume = base area * h
Base area * height = Volume
15 * height = 180
height = 180/15
height = 12 inches

Kabita has two bags. In the first bag there are 5 blue discs and 3 red discs. In the second bag there are 7 blue discs and 4 red discs. Kabita takes at random a disc from the first bag. She then takes at random a disc from the second bag
Work out the probability that kABITA takes 2 red discs
The probability that Kabita would take 2 red discs from the bags is 3/22.
What is probability?Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.
The probability that Kabita would take 2 red discs = (number of red discs in bag 1 / total number of discs in bag 1) x (number of red discs in bag 2 / total number of discs in bag 2)
(3/8) x (4/11) = 3/22

5. For the data in the table below, find the sum of the absolute deviations for the predicted values
given by the median-median line, y = 3.6x-0.4.
Based on the absolute deviations and the predicted values, the sum of absolute deviations will be 4.8.
What would be the sum of absolute deviations from predicted values?This can be found as:
= ∑ (Observed value - Predicted value)
The observed values are given in the table and the predicted values will be calculated using y = 3.6x - 0.4.
Solving gives:
= [3 - (3.6 x 1 - 0.4)] + [7 - (3.6 x 2 - 0.4)] + [ 9 - (3.6 x 3 - 0.4)] + [14 - (3.6 x 4 - 0.4)] + [15 - (3.6 x 5 - 0.4)] + [21 - (3.6 x 6 - 0.4)] + [25 - (3.6 x 7 - 0.4)]

(q+4)(9q+5)=0 solve for q
Answer:
q = -4
q = -5/9
Step-by-step explanation:
Hi!
To solve this question, we can use the zero product property.
The zero product property states that if one factor is equal to 0, then the whol equation is equal to 0.
We have (q+4)(9q +5) = 0
That means either q + 4 = 0, or 9q + 5 = 0.
Solve:
q + 4 = 0q = -49q + 5 = 09q = -5q = -5/9We can check both cases:
(-4 + 4)(-36 + 5) = 0
0(-31) = 0
0 = 0
(-9/5 + 4)(9(-5/9) + 5) = 0
(2.2)(-5 + 5) = 0
(2.2)0 = 0
0 = 0

Given :-We have given two parallel lines and two lines intersecte each other and act as a transverse Due to the intersection between two parallel and two traverse lines a triangle is formed. The measurements of the given triangle are 60° , 20° and C To Find :-We have to find the values of angles A, B and C Let's Begin :-Here, we have
1 triangle whose measures are 60° , 20° and CTherefore,By using Angle sum property
ASP states that the sum of all angles of triangles are equal to 180°That,
[tex]\bold{\angle{X + }}{\bold{\angle{Y + }}}{\bold{\angle{Z = 180}}}{\degree}[/tex]
Subsitute the required values,
[tex]\sf{ 60{\degree} + 20{\degree} + C = 180{\degree}}[/tex]
[tex]\sf{ 80{\degree} + C = 180{\degree}}[/tex]
[tex]\sf{ C = 180{\degree} - 80{\degree}}[/tex]
[tex]\sf{ C = 100}{\degree}[/tex]
Thus, The value of C is 180°
Now,We have to find the measurement of Angles A and B
Here,
Angle B , unknown angle and Angle C lie on a straight line and we know that the angle formed by straight line is 180°Let the unknown angle be x which is equal to 20° ( Alternative interior angles) Therefore,[tex]\sf{\angle{B + }}{\sf{\angle{ x + }}}{\sf{\angle{C = 180}}}{\degree}[/tex]
[tex]\sf{\angle{ B + 20{\degree}+ 100{\degree} = 180{\degree}}}[/tex]
[tex]\sf{\angle{ B + 20{\degree} = 180{\degree}- 100{\degree}}}[/tex]
[tex]\sf{\angle{ B = 80{\degree} - 20{\degree}}}[/tex]
[tex]\sf{\angle{ B = 60{\degree}}}[/tex]
Now, A, B and 100° lie on a straight line and we know that the angle formed by straight line is equal to 180°Therefore ,[tex]\sf{\sf{A + }}{\sf{\angle{B + }}}{\sf{ 100{\degree} = 180}}{\degree}[/tex]
[tex]\sf{\angle{ A + 60{\degree} = 180{\degree} - 100{\degree}}}[/tex]
[tex]\sf{\angle{ A = 80{\degree} - 60{\degree}}}[/tex]
[tex]\sf{\angle{ A = 20{\degree}}}[/tex]
Hence, The measure of Angles A, B and C are 20° , 60° and 100° .
What is the value of w?
Answer:
w = 60
Step-by-step explanation:
the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
w + 20 is an exterior angle of the triangle , then
w + 20 = w - 10 + w - 30
w + 20 = 2w - 40 ( subtract w from both sides )
20 = w - 40 ( add 40 to both sides )
60 = w
Answer:
w=60°
Step-by-step explanation:
triangle=180°
angle on a straight line=180°
using that,
we need to find the angle on the same line with that of "w+20°" angle, so we name it as "X"
so, 180-(w+20)=X
expand bracket by multiplying it with the "-"
so it'll be: 180-w-20=X
then rearrange to get like terms together
180-20-w=x
160-w=x
so the missing angle in the triangle is now (160-w)°
now using the angles in a triangle =180°
we add all the angles and equate it to 180, so:
w-30+w-10+160-w=180°
collect like terms again:
w+w-w-30-10+160=180
2w-w+120=180
w+120=180
move 120 to the other side and remember the sign changes, so:
w=180-120
therefore w=60°
now you can substitute w=60 into the triangle and see you'll get 180°
hope that helps

Answer:
x ≈ 44°
Step-by-step explanation:
We will use a trigonometry function to solve for x. We can see that we have values for the adjacent side and hypotenuse. This means we will be using cosine. Cosine is [tex]\frac{adjacent }{hypotenuse}[/tex]
cos(x) = [tex]\frac{adjacent }{hypotenuse}[/tex] [Given]
cos(x) = [tex]\frac{4.9}{6.8}[/tex] [Plug-in the values we have]
x ≈ 43.8969 [Find the inverse cosine function of both sides]
x ≈ 44° [Rounding to nearest degree]
