Answer:
1440 degrees.
Step-by-step explanation:
125 + 140 + 160 = 425 degrees.
The remaining angles are each 145.
The exterior angles of all polygons sum to 360 .
So we have exterior angles sum of the 3 given angles
= (180-125) + ( 180-140) + (180-160)
= 55 + 40 + 20 = 115.
So the remaining vale of the sum is 360 - 115
= 245 degrees.
An internal angle of 145 will give an external one of 35 degrees.
245/35 = 7.
So there are 7 145 degree angles in the polygon.
Sum of the interior angles is therefore:
425 + 7*145
= 1440 degrees.
This is a 10 sides polygon ( a decagon).
The equation A= 1750(1.04)t represents an account balance t years after the account was created. Which statement is correct?
A. The account balance will decrease 0.04% each year.
B. The account balance will increase 0.04% each year.
C. The account balance will decrease 4% each year.
D. The account balance will increase 4% each year.
Answer:
D. The account balance will increase 4% each year.
Step-by-step explanation:
Given the equation :
A= 1750(1.04)t
This is an exponential growth rate equation which has it's general format as :
A = A0 * (1 + r)^t
A0 = initial value,
Since (1 + r) is greater Than 1 ; then we conclude that it is a growth relation.
1 + r = 1.04
The rate, r = (1.04 - 1) = 0.04
r = 0.04 = (0.04 * 100%) = 4%
Hence, The account balance will increase 4% each year.
Suppose that a family has an equally likely chance of having a cat or a dog. If they have two pets, they could have 1 dog and 1 cat, they could have 2 dogs, or they could have 2 cats.
What is the theoretical probability that the family has two dogs or two cats?
Describe how to use two different coins to simulate which two pets the family has.
Flip both coins 50 times and record your data in a table like the one below.
Result Frequency
Heads, Heads
Heads, Tails
Tails, Heads
Tails, Tails
Total 50
Based on your data, what is the experimental probability that the family has two dogs or two cats?
If the family has three pets, what is the theoretical probability that they have three dogs or three cats?
How could you change the simulation to generate data for three pets?
The theoretical probability that the family has two dogs or two cats is 1/3.

Step-by-step explanation:
whats the measure of angle E ?
Answer:
57degrees
Step-by-step explanation:
The triangle is an isosceles triangle, hence m<D = m<E (base angles are equal)
Taking the sum of the angles and equating to 180
5x-4 + 4x+1 + 4x+1 = 180
5x+4x+4x-4+1+1 = 180
13x - 2 = 180
13x = 180 + 2
13x = 182
x =182/13
x = 14
Get m<E
m<E = 4x+ 1
m<E = 4(14)+ 1
m<E = 56+1
m<E = 57degrees
Hence the measure of m<E is 57degrees

Seth bought glow-in-the-dark stars to
put on his ceiling. There are 5 big stars
and 25 little stars. He wants to make
constellations that each have 1 big
star. If he uses the same amount of
stars for each constellation, how many
little stars will each have?
Answer:
Each constellation will have 5 little stars.
Step-by-step explanation:
First, let's organize the information we have:
5 big stars25 little starsEach constellation should have 1 big starEach constellation should have the same amount of starsNow, let's solve the problem:
Each constellation should have 1 big star, and Seth has 5 big stars, so we can infer that there would be 5 constellations.Since each constellation have 1 big star, and the amount of stars in each constellation is the same, the amount of little stars in each constellation are the same.We have 25 little stars, and there are 5 constellations; 25 ÷ 5 = 5, so each constellation have 5 little stars.it's been 2 hours and no one answered my question what the heck

Question of
Two sides of a trangle have the following measures 7, 10 Find the range of possible measures for the third side.
Answer:
3 < x < 17
Step-by-step explanation:
Given 2 sides of a triangle then the third side x is in the range
difference of 2 sides < x < sum of 2 sides , that is
10 - 7 < x < 10 + 7
3 < x < 17
Q9 The number that happens the most: *
A Mean
B Median
C Mode
D Range
Answer:
C
Step-by-step explanation:
The mode is the value that appears most often in a set of data values. If X is a discrete random variable, the mode is the value x at which the probability mass function takes its maximum value. In other words, it is the value that is most likely to be sampled.
Which of the following would not be a line in solving the equation:
7x-8-5x = 52
12x = 60
12x = 44
12x - 8 = 52
x = 5
Answer:
Step-by-step explanation:
Let's actually solve the equation. By doing so we should readily see which of the given equatins are not part of the solution.
7x - 8 - 5x = 52 becomes 2x - 8 = 52 if we consolidate the x terms. Next, we consolidate the constant terms on the right, obtaining 2x = 60.
Then x = 30 is the solution.
12x = 60 would not be part of the solution.
12x = 44 would not either.
12x - 8 = 52 would not either.
x = 5 would not be part of the solution.
Again: The solution is x = 30.
A triangular pyramid has a volume of 48 in3. The base edge is 9 in and the base height is 4 in. Find the height of the pyramid.
Answer:
8 in
Step-by-step explanation:
First of all we have to find the area of the base triangle.
For do this we can use this formula:
A = (base edge x base height)/2
A = (9 x 4)/2 = 18 in^2
The formula for find the volume of a pyramid is:
V= Base area x height)/3
So the height can be find in this way
3 x V = base area x height
height = (3 x V)/base area
height = (3 x 48)/18 = 8 in
Answer:
pretty sure it is 8in I think

HELP!!!!!! BRAINLIEST AWARD!!!!!!
help with math problem below:
Answer:
Antonio is the right one
Answer:
∠ A = 123°
Step-by-step explanation:
The central angle A is equal to the arc that subtends it , so
∠ A = arc DE = 5x - 2
The angles subtended by the radii and tangents of a circle are supplementary
2x + 7 + 5x - 2 = 180 ← Antonio is correct
7x + 5 = 180 ( subtract 5 from both sides )
7x = 175 ( divide both sides by 7 )
x = 25
Then
∠ A = 5 - 2 = 5(25) - 2 = 125 - 2 = 123°

Indicate the equation of the given line in standard form.
The line that contains the point Q( 1, -2) and is parallel to the line whose equation is
y - 4 = 2/3 (x - 3)
Answer:
The equation of the line is;
3y = 2x-8
Step-by-step explanation:
Firstly, we need the to get the slope of the given line
To do this, we will write the equation of the line in the standard form
the standard form
is;
y = mx + b
where m is the slope and b is the y-intercept
y -4 = 2/3(x-3)
y -4 = 2x/3 - 2
y = 2x/3 -2 + 4
y = 2x/3 + 2
with respect to the given equation, the slope of the line is 2/3
Mathematically, when two lines are parallel, the slopes of the line are equal
So now, we want to find the equation of the line that has a slope of 2/3 and passes through the point (1,-2)
so;
y = 2x/3 + b
So substitute the values of (1,-2)
1 for x and -2 for y
-2 = 2/3(1) + b
-2 = 2/3 + b
b = -2 - 2/3
b = (-6-2)/3 = -8/3
So the equation of that line is;
y = 2/3x - 8/3
Multiply through by 3
3y = 2x - 8
