Answer:
Step-by-step explanation: option b
d. Could the triangle have 110 cans? 140 cans? Explain.
NO, for such a triangle to exist is impossible.
We are given two angles of 110° and 140°.
We have to find whether Triangle with given angles (110° and 140°) is possible or not.
We will utilize the basic knowledge of triangles and their angles to solve this problem. As we know, the sum of all triangle angles is 180°.
If
let the third angle be x
110° + 140° + x = 180
according to the angle sum property of triangles
then,
x = 180° - 250°
which is not possible.
And if we add 110 and 140, we will get 250° as a resultant, which is much greater than the sum of the three angles.
Therefore, a triangle with 110° and 140° as two of its angles is not possible.

Determine whether each sequence is arithmetic. If so, identify the common difference. 100,10,1,0.1, ...........
The given sequence 100,10,1,0.1, ........... does not form an AP as the common difference is not same.
What is the sequence of AP arithmetic progression?In Arithmetic Progression, the difference between two mathematical orders is a fixed number (AP). Arithmetic Sequence is another name for it.
We'd come across a few key concepts in AP that had been labeled as:
The first term (a)Common difference (d)Term nth (an)The total of first n terms (Sn)As shown below, the AP can also be referred to in terms of common differences.
The following is the procedure for evaluating an AP's n-th term: an = a + (n − 1) × dThe arithmetic progression sum is as follows:Sn = n/2[2a + (n − 1) × d].Common difference 'd' of an AP: d = a2 - a1 = a3 - a2 = a4 - a3 = ...... = an - an-1.Now, the stated sequence is; 100,10,1,0.1, ...........
The series comprises of four defined terms.
Consider the initial term be 'a₁' = 100.
Consider the second term be 'a₂' = 10.
Consider the third term be 'a₃' = 1.
And, consider the fourth term is 'a₄' = 0.1.
The AP must have the equal common difference. So,
d₁ = a₃ - a₂
Substitute the values.
d₁ = 1 - 10
d₁ = -9
Thus, the computed common difference is -9.
or d₂ = a₄ - a₃ (Substitute the values)
d₂ = 0.1 - 1
d₂ = -0.9.
As, for the result it is clear that the value of both common difference is not same. That is,
d₁ ≠ d₂.
Therefore, the given sequence doesn't not form an arithmetic sequence.

The 20th term of the given geometric sequence, 3, 12, 48, 192, . . . , is 8.246337208 x 10^11.
A geometric sequence refers to a sequence of numbers, which the next term is obtained by multiplying the previous term with a constant, called a ratio.
a(n) = a r^(n-1)
Where:
a(n) = nth term
r = ratio
Given the geometric sequence 3, 12, 48, 192, . . .
Find the ratio,
r = a(n)/a(n-1)
r = a(2)/a(1)
r = 12/3
r = 4
Notice that the ratio between two succeeding terms is always 4.
Use the formula to find the 20th term of the geometric sequence.
a(20) = a r^(20-1)
a(20) = 3[4^(20-1)]

∠AHF is the exterior angle to the triangle GHI, so m∠AHF = 116°.
What is exterior angle?
When one side of a triangle is stretched, an external angle is generated. An external angle of a triangle is a non-straight angle (one that is not merely an extension of a side) that is outside the triangle but next to an interior angle.
From figure, m∠CIH = 105° (given)
so, m∠GIH = (180° - m∠CIH) = (180° - 105°) = 75° (complementary angles)
And m∠BGD = 41°
So, m∠IGH = M∠BGD = 41° (vertically opposite angles)
Now, m∠AHF = m∠GIH + m∠IGH (exterior angle)
= 75° + 41°
= 116°

A bee flies at 6 feet per second directly to a flowerbed from its hive. The bee stays at the flowerbed for 11 minutes, and then flies directly back to the hive at 4 feet per second. It is away from the hive for a total of 15 minutes. a. What equation can you use to find the distance of the flowerbed from the hive? b. How far is the flowerbed from the hive?
Answer:
576 feet
Step-by-step explanation:
The bee is at the flowerbed for 11 minutes so we can subtract that form the 15 minutes. The bee travels for 4 minutes.
So now we have that it flew to the flowerbed at 6 feet per second and back at 4 feet per second.
We have a total of 4 minutes or 240 seconds. we now have two speeds where one is 50% faster than the other. We then find the two percents that one is 50% greater than the other percent and both add up to 100. 40% +50% of 40% is 60. 60%+40% is 100%
We know it spent 40% of 240 seconds flying to the flowerbed at 6 feet per second.
40% of 240 is 96
96 seconds at 6 feet per second is 576 feet
Miranda purchased a coat for $101.50 that was regularly priced at $145, not including tax. what percentage did miranda save by purchasing a coat on sale?
If Miranda purchased a coat for $101.50 that was regularly priced at $145, not including tax then the percentage Miranda saved by purchasing the coat on sale is equal to 30%.
Percentage in mathematics can be described as a number expressed as a fraction of 100. The symbol % is used to indicate a percent.
The percentage Miranda saved by purchasing the coat on sale can be calculated as follows,
First, subtract the regular price from the price at which she purchased
145 - 101.50 = 43.5
Now, divide this number by the regular price of the coat,
43.5 ÷ 145 = 0.3
Now, the percentage Miranda saved can be calculated by multiplying the result by 100,
0.3 × 100 = 30%
Hence, the percentage Miranda saved by purchasing the coat on sale is calculated to be 30%.

Your teacher invested twice as much in the income fund as in the money market fund. How much money was invested in each fund?
Using a system of equations, the amounts invested in each fund are given as follows:
Growth: $2,000.Income: $2,000.Market: $2,000.What is a system of equations?A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
For this problem, the variables are given as follows:
Variable x: amount invested into the growth fund.Variable y: amount invested into the income fund.Variable z: amount invested into the market fund.The teacher invested 5000, hence:
x + y + z = 5000.
After a year, the amount was of $5,450, hence, considering the return rates:
1.12x + 1.08y + 1.05z = 5450.
The teacher invested twice as much in the income fund as in the money market fund, hence:
y = 2z.
Then, replacing y = 2z in the first two equations:
x + 3z = 5000 -> x = 5000 - 3z.1.12x + 3.21z = 5450.Replacing the first equation into the second.
1.12(5000 - 3z) + 3.21z = 5450.
0.15z = 150
z = 150/0.15
z = 1000.
Hence:
y = 2z = 2000.x = 5000 - 3z = 2000.The amounts invested in each fund are given as follows:

{y | −∞ < y < ∞}
{y | −3 ≤ y < ∞}
{y | 0 ≤ y < ∞}
{y | 3 ≤ y < ∞}
A function is defined as a relation between a set of inputs having one output each.
The inputs are called the domain and the outputs are called the range.
The range for the function f(x) = |x| + 3 is {y | 3 ≤ y < ∞}.
What is a function?A function is defined as a relation between a set of inputs having one output each.
The inputs are called the domain and the outputs are called the range.
We have,
f(x) = |x| + 3
We need to find the range of f(x).
We can have x values of any real numbers.
For x = 0,
f(0) = 0 + 3 = 3
For x = 1,
f(1) = 1 + 3 = 4
For x = 2,
f(2) = 2 + 3 = 5
For x = 3
f(-3) = |-3| + 3 = 6
For x = -1,
f(-1) = |-1| + 3 = 1 + 3 = 4
For x = -2,
f(-2) = |-2| + 3 = 2 + 3 = 5
For x = -3,
f(-3) = |-3| + 3 = 3 + 3 = 6
We see that,
If we take x = 0, 1, 2, 3, 4, .... the f(x) values increases from 3, 4, 5, 6 and so on.
If we take x = 0 , -1, -2, -3, ..... the f(x) values increases from 3, 4, 5, 6 and so on.
This means that f(x) values are from 3 to infinity for x ∈ R
