Lines A and b are parallel and lines e and f are parallel. If m<1=89, what is the measure of <5?
M<5=?
Answers
Answer:
Given the statement:
Lines a and b are parallel and lines e and f are parallel.
if [tex]m \angle 1 = 89^{\circ}[/tex]
By supplementary angles:
[tex]m\angle 1+ m\angle 2 = 180^{\circ}[/tex]
⇒[tex]89^{\circ}+ m\angle 2 = 180^{\circ}[/tex]
Subtract 89 degree from both sides we have;
[tex]m \angle 2 = 91^{\circ}[/tex]
Since,
m∠4 = m∠5 [Vertically Opposite angles] .....[1]
m∠4 = m∠3 [Alternate Interior angle] .....[2]
By [1] and [2] we have;
m∠5 =m∠3 ....[3]
Also;
m∠2 = m∠3 [Alternate interior angle] ....[4]
by [3] and [4] we have;
m∠5 = m∠2
Substitute the given values we have;
[tex]m \angle 5 = 91^{\circ}[/tex]
Therefore, the measure of [tex]m \angle 5[/tex] is, [tex]91^{\circ}[/tex]

What is the value of this expression? (-8)3
Answers
Answer:
Step-by-step explanation:
You could, if you wished, take out the negative sign, obtaining -(8)(3). That would be -24.
But if you meant exponentiation, it would look like (-8)^3, or (-8)³, and that would be equal to 8*8*8 = 512.
Erica bought 3 1/2 yards of Frederick if she uses 2/3 of the fabric to make a curtain how much will she have left
Answers
3 1/2
3*2=6
6+1=7
3 1/2 as an improper fraction would be 7/2
Now we multiply the fractions.
7/2*2/3
7*2=14
2*3=6
14/6
Now we can convert the improper fraction back into a proper fraction.
How many times does 6 fit into 14? 2 with a remainder of 2
The Fraction would be: 2 2/6 or reduced to 2 1/3
She used 2 1/3 yards of fabric.
The question asks for how much she has left so, we must subtract 2 1/3 from 3 1/2
However, we must have a common denominator to subtract.
To find this, we can list the multiples of both of the denominators:
2: 2,4,6,8,10
3: 3,6,9,12,15
The LCM (Lowest Common Denominator) is 6.
2*3=6
3*2=6
We must do the same for the numerator as what is done for one-half has to be done for the other.
1*3=3
1*2=2
The New fractions would be:
3 3/6
and
2 2/6
Now we can subtract ;
3-2=1
3-2=1
We don't subtract the denominator
The answer is 1 1/6.
Erica would have 1 1/6 of the curtain left.

The directions for mixing an insect spray say to use 1 3/4 ounces of chemical in each gallon of water. How many ounces of chemical should be mixed with 4 1/5 gallons of water?
Answers
Now convert the new water gallons to an improper fraction: 4 1/5 gallons
--> 21/5 gallons
Now 21/5 gallons water × 7/3oz./gallon water = 21×7/5×3 = 7×7/5 = 49/5oz.--> convert to mixed number: 9 4/5oz. chemical in order to make 4 1/5 gallons of mixture.
7 7/20 ounces of chemical should be mixed with 4 1/5 gallons of water.
To determine the amount of chemical to mix with 4 1/5 gallons of water, you need to use the given ratio of 1 3/4 ounces of chemical per gallon of water.
1.) Convert 4 1/5 gallons to a mixed number:
4 1/5 = 21/5 gallons.
2.) Multiply the amount of water by the chemical-to-water ratio:
(21/5) gallons * (7/4) ounces = 147/20 ounces.
3.) Convert 147/20 ounces to a mixed number:
147/20 = 7 7/20 ounces.
Therefore, 7 7/20 ounces of chemical should be mixed with 4 1/5 gallons of water.

How is inductive reasoning used in geometry?
Answers
Answer:
Inductive reasoning draws general conclusions from specific details / observations - in other words, going from specific --> general.
Example:
Specific: I break out when I eat peanuts.
Observation: This is a symptom of being allergic.
General Conclusion: I am allergic to peanuts.
hope this helps! <3
Final answer:
Inductive reasoning in geometry involves observing patterns in specific instances and formulating general rules or hypotheses, such as the sum of angles in a triangle or the properties of parallel lines intersected by a transversal.
Explanation:
Inductive reasoning in geometry is used to derive broad generalizations from specific observations or instances. One way inductive reasoning is applied is by observing patterns or properties in a set of geometric figures and then formulating a hypothesis or general rule that applies to all similar figures. For example, after measuring the angles of several triangles and finding that they always add up to 180 degrees, one might assume that all triangles have this property. Another example is when looking at multiple parallel lines cut by a transversal and noticing the corresponding angles are equal, thus generalizing that this is the case for any parallel lines intersected by a transversal.
Scientists, including mathematicians, use inductive reasoning to construct hypotheses, which are then tested using deductive reasoning. The conclusions drawn from inductive reasoning may not always be correct, but they are essential for advancing scientific and mathematical knowledge by suggesting relationships and rules that can be rigorously tested.

For what value of a does 9=(1/27)^a+3
Answers
[Note: Please review rules of PEMDAS.
The question posted as is means
9=[(1/27)^a]+3 which is probably not what you mean. It has been interpreted with (a+3) as the exponent, please check.]
Need to find value of a that satisfies above.
We will first isolate a in order to solve for its value.
9=(1/27)^(a+3)
Switch unknown to the left
(1/27)^(a+3) = 9
Since both 27 and 9 are powers of 3, we can take log to base 3.
take log (base 3) on both sides, applying rule of logarithm of exponents.
(a+3)log_3(1/27)=log_3(9)
(a+3)log_3(3^(-3))=log_3(3^2)
Apply definition of logarithm [log_a(a^k)=k]
(a+3)(-3)=2
(a+3)=-2/3
a=-3 2/3=-11/3
Check: (1/27)^(-11/3+3)=(1/27)^(-2/3)=(3^(-3))^(-2/3)=3^(-3(-2/3))=3^2=9 ok
Answer: a=-11/3 or a=-3.667 (approx.)
The value of a in the equation [tex]9=(\frac{1}{27})^{a+3}[/tex] is a = -11/3
Solving indical equationsThe given equation is:
[tex]9=(\frac{1}{27})^{a+3}[/tex]
This can be rewritten as:
[tex]9=27^{-1(a+3)}[/tex]
Which can be further simplified as:

Since the bases are equal, they cancel out
The equation becomes:
2 = -3(a + 3)
2 = -3a - 9
2+9 = -3a
-3a = 11
a = -11/3
Therefore, the value of a in the equation [tex]9=(\frac{1}{27})^{a+3}[/tex] is a = -11/3

now, how many days? simply multiply t * 365.
It would take approximately 39 years and 183 days for the deposit to grow to $1 million.
Use the concept of compound interest defined as:
The interest that is computed using both the principal and the interest that has accrued during the previous period is called compound interest. It differs from simple interest in that the principal is not taken into account when determining the interest for the subsequent period with simple interest.
Given that,
Initial deposit: $1300
Target amount: $1 million
Interest rate: 17%
Compounding: Continuous
Time to calculate: To the nearest day
To find the amount of time it would take,
Use the formula:
[tex]t = \dfrac{ln(\frac{M}{P})}{r}[/tex]
Where,
t = time in years
M = final amount ($1 million)
P = initial deposit ($1300)
r = interest rate (17% or 0.17)
Find the natural logarithm of the ratio M/P:
ln(1,000,000 / 1,300) ≈ 6.64
Divide the result by the interest rate:
t = 6.64 / 0.17
t ≈ 39.05 years
So, it would take approximately 39 years to grow the deposit to $1 million.
To determine the number of days,
Multiply the decimal part of the years by 365 (assuming a non-leap year):
0.05 x 365 ≈ 183 days
Hence,
Rounding to the nearest day, it would take approximately 39 years and 183 days for the deposit to grow to $1 million.

Answer:
Length of the shadow is 11.8 meters.
Step-by-step explanation:
In the figure attached,
AB is a 34 meter tall building casting a shadow BC.
Let the measure of BC = x meters
It is given that the distance between A and C is 36 meters.
To find the length of BC we will apply Pythagoras theorem in the triangle.
AB² + BC² = AC²
(34)² + x² = (36)²
1156 + x² = 1296
x² = 1296 - 1156
x² = 140
x = √140
x = 11.832 meters
≈ 11.8 meters
Therefore, length of the shadow will be 11.8 meters.

vito just put some money into a cd that pays 12.7 interest compound quarterly. according to the rule of 72,in the approximately how years will he have 4 times the amount of money that he has now
Answers
Answer:
11.34 years.
Step-by-step explanation:
We have been Vito put some money into a cd that pays 12.7 interest compound quarterly.
Since the rule of 72 states that to find the number of years it will take an amount to double, we need to divide 72 by annual interest rate.
First of all let us find the number of years it will take to double Vito's money by dividing 72 by 12.7.
[tex]\text{Time it will take to double Vito's money}=\frac{72}{12.7}[/tex]
[tex]\text{Time it will take to double Vito's money}=5.66929133858\approx 5.669[/tex]
Since it will take 5.669 years to double Vito's money, so to find the time it will take Vito to have 4 times the money, we will multiply 5.669 by 2.
[tex]\text{Time it will take to have 4 times Vito's money}=5.669*2[/tex]
[tex]\text{Time it will take to have 4 times Vito's money}=11.338\approx 11.34[/tex]
Therefore, approximately in 11.34 years Vito will have 4 times the amount of money that he has now.

an ellipse has a center at the origin, a vertex along the major axis at (13, 0), and a focus at (12, 0). What is the equation of the ellipse?
Answers
Answer: The equation of the ellipse is
[tex]\dfrac{x^2}{169}+\dfrac{y^2}{25}=1.[/tex]
Step-by-step explanation: We are given to find the equation of an ellipse that has a center at the origin, a vertex along the major axis at (13, 0) and a focus at (12, 0).
Since the focus lies on the X-axis, so the standard equation of an ellipse with major axis as X-axis is given by
[tex]\dfrac{x^2}{a^2}+\dfrac{y^2}{b^2}=1~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]
According to given information, we have
a vertex along the major axis, (a, 0) = (13, 0)
⇒ length of the major axis, a = 13,
co-ordinates of focus, (c, 0) = (12, 0)
⇒ c = 12.
We know that
[tex]c^2=a^2-b^2.[/tex]
Therefore,
[tex]12^2=13^2-b^2\\\\\Rightarrow 144=169-b^2\\\\\Rightarrow b^2=169-144\\\\\Rightarrow b^2=25\\\\\Rightarrow b=5.[/tex]
Thus, from equation (i), we get
[tex]\dfrac{x^2}{a^2}+\dfrac{y^2}{b^2}=1\\\\\\\Rightarrow \dfrac{x^2}{13^2}+\dfrac{y^2}{5^2}=1\\\\\\\Rightarrow \dfrac{x^2}{169}+\dfrac{y^2}{25}=1.[/tex]
The equation of the ellipse is
[tex]\dfrac{x^2}{169}+\dfrac{y^2}{25}=1.[/tex]
The equation of the ellipse along the major axis at (13, 0), and a focus at (12, 0) is; x²/169 + y²/25 = 1
Equation of an ellipseThe equation of an ellipse whose center is the origin, (0,0) usually takes the form;
x²/a² + y²/b² = 1The coordinates of the vertex on the major axis is given as; (13,0) and the focus at (12,0)
Hence, the square of the length of the minor axis;
b² = a² - c²b² = 169 - 144b² = 25.Hence, the equation of the described ellipse is;
x²/169 + y²/25 = 1Read more on equation of an ellipse;
