Two angels re supplementary. The larger angle is 48 degrees more than the 10 times the smaller angle. Find the measure of each angle.
Answers
STEP 1:
find the value of x
x= smaller angle
10x + 48= larger angle
Add the two angles above to equal 180.
x + (10x + 48)= 180
combine like terms
11x + 48= 180
subtract 48 from both sides
11x= 132
divide both sides by 11
x= 12° smaller angle
STEP 2:
find the value of the second angle
=10x + 48
=10(12) + 48
=120 + 48
=168° larger angle
CHECK:
12° + 168°= 180°
180°= 180°
ANSWER: The smaller angle is 12° and the larger angle is 168°.

Mark runs 3/4 of a mile each day for 5 days. What is the total distance that Mark has run after 5 days? A.3 3/4 B.4 1/4 C.5 3/4 D.6 2/3
Answers
Your answer is A.
Final answer:
To find the total distance Mark has run after 5 days, multiply his daily distance of 3/4 mile by 5 days, resulting in A.3 3/4 miles.
Explanation:
The question asks us to find the total distance that Mark runs over 5 days, given that he runs 3/4 of a mile each day. To find the total distance, we simply multiply the daily distance by the number of days.
Multiply the daily distance (3/4 mile) by the number of days (5 days):
(3/4) × 5 = 15/4
Convert the improper fraction to a mixed number:
15/4 is equivalent to 3 whole miles and 3/4 of a mile, which can be written as 3 3/4 miles.
Therefore, after 5 days, Mark has run a total distance of A.3 3/4 miles.

need help for question one in polynomials
Answers
Answer:
a) monomial
b) constant
c) binomial
d) trinomial
e) binomial
f) constant
g) monomial
Step-by-step explanation:
Let's start by defining the terms in the question:
A monomial is an expression with a single term, regardless of how many variables are in the term.
A binomial is an expression with two different terms, which cannot be combined into a single term due to their variables not matching.
A trinomial is an expression with three different terms, which cannot be combined into a binomial or monomial because their variables do not match.
A constant is an integer that lacks a variable attached to it. An integer with a variable attached to it would be a monomial, and the integer itself would be called a coefficient.
Now, we can get into the parts of the question:
a) 8a²b is two variables however it is still a single term so this is a monomial.
b) -39 is an integer with no variables attached. Therefore, it is a constant.
c) x + y is two variables and two different terms that cannot be combined into one single term. It is a binomial.
d) -12xy + 5y - x² showcases three different variables and three different terms that cannot be consolidated. Thus, it is a trinomial.
e) 2x² + 2y² demonstrates two different variables and two different terms that are not alike. As such, we have a binomial.
f) 3/4 is an integer with no variables in sight. We have here a constant.
g) -32m²n² has two variables but is only a single term on its own. This is a monomial.

A.17.8%
B.23.7%
C.42.2%
D.31.6%
Answers
Answer:
The correct answer is C. 42.2%
Step-by-step explanation:
Total number of cards in the deck of playing cards = 52
Number of spades in the deck of playing cards = 13
Number of cards other than spade = 52 - 13
= 39
If she draws a card 3 times and doesn't get a spade, she loses.
So, She loses only if he gets all the three cards other than spade
[tex]\text{Probability that she does not get a spade in first draw = }\frac{39}{52}[/tex]
Now, The card is replaced if she does not get a spade.
[tex]\text{So, Probability that she does not get a spade in second draw = }\frac{39}{52}[/tex]
[tex]\text{Similarly, Probability that she does not get a spade in third draw = }\frac{39}{52}[/tex]
[tex]\text{Thus, Probability that she will lose the game = }\frac{39^3}{52^3}=0.422[/tex]
[tex]\text{Also, The percentage of Probability that she will lose the game = }0.422\times 100=42.2\%[/tex]
Hence, The correct answer is C. 42.2%

The width of a rectangle is 6 kilometers less than twice its length. if its area is 108 square kilometers, find the dimensions of the rectangle.
Answers
2x - 6 = the width as given in the description.
Area of a rectangle is length * width. Now we plug in.
108 = x(2x - 6)
108 = 2x² - 6x
We are going to get all terms on the same side and factor.
2x² - 6x - 108 = 0
Factor out and divide each term by a GCF of 2 to get:
x² - 3x - 54 = 0
x² + 6x - 9x - 54 = 0
x(x + 6) - 9(x + 6) = 0
Your factors are (x + 6)(x - 9) = 0. Now we set each binomial equal to zero. This gives us x = - 6 and x = 9. Distance cannot be measure in negative numbers so we know to use x = 9 to find our measurements.
The length (x) is 9 kilometers. The width (2x - 6) is 12 kilometers when you plug in 9 where the x is.
The dimensions of the rectangle are [tex]\( \boxed{9 \text{ km} \times 12 \text{ km}} \)[/tex].
Let's denote the length of the rectangle as [tex]\( l \)[/tex] kilometers, and its width as [tex]\( w \)[/tex] kilometers.
From the problem statement, we have two pieces of information:
1. The width is 6 kilometers less than twice the length:
[tex]\[ w = 2l - 6 \][/tex]
2. The area of the rectangle is 108 square kilometers:
[tex]\[ lw = 108 \][/tex]
Now we can substitute the expression for \( w \) from the first equation into the second equation:
[tex]\[l(2l - 6) = 108\][/tex]
Expand and simplify the equation:
[tex]\[2l^2 - 6l = 108\][/tex]
Subtract 108 from both sides to set the equation to zero:
[tex]\[2l^2 - 6l - 108 = 0\][/tex]
Divide every term by 2 to simplify:
[tex]\[l^2 - 3l - 54 = 0\][/tex]
Now, we'll solve this quadratic equation using the quadratic formula, [tex]\( l = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \)[/tex], where [tex]\( a = 1 \)[/tex], [tex]\( b = -3 \)[/tex], and [tex]\( c = -54 \)[/tex]:
[tex]\[l = \frac{-(-3) \pm \sqrt{(-3)^2 - 4 \cdot 1 \cdot (-54)}}{2 \cdot 1}\][/tex]
[tex]\[l = \frac{3 \pm \sqrt{9 + 216}}{2}\][/tex]
[tex]\[l = \frac{3 \pm \sqrt{225}}{2}\][/tex]
[tex]\[l = \frac{3 \pm 15}{2}\][/tex]
This gives us two possible solutions for [tex]\( l \)[/tex]:
[tex]\[l = \frac{18}{2} = 9 \quad \text{or} \quad l = \frac{-12}{2} = -6\][/tex]
Since length cannot be negative, we take [tex]\( l = 9 \)[/tex] kilometers.
Now, substitute [tex]\( l = 9 \)[/tex] back into the expression for [tex]\( w \)[/tex]:
[tex]\[w = 2l - 6 = 2 \cdot 9 - 6 = 18 - 6 = 12\][/tex]
Therefore, the dimensions of the rectangle are:
- Length [tex]\( l = 9 \)[/tex] kilometers
- Width [tex]\( w = 12 \)[/tex] kilometers
To verify, calculate the area:
[tex]\[l \times w = 9 \times 12 = 108 \text{ square kilometers}\][/tex]
Since this matches the given area, the dimensions [tex]\( l = 9 \)[/tex] kilometers and [tex]\( w = 12 \)[/tex] kilometers are correct.
Thus, the dimensions of the rectangle are [tex]\( \boxed{9 \text{ kilometers} \times 12 \text{ kilometers}} \)[/tex].

Given that ABCD is a rhombus, find the value of x (x-10)
Answers
To start, a rhombus will have perpendicular bisectors.
With that, we know that the section where these bisectors cross will create 90 degree angles.
So now we have angles: x, (x-10), and 90.
A triangle will total 180 degrees in total. So if we add up all of these angles, it will total to exactly 180.
In other words: 90+x+(x-10)=180.
So, in this situation, we want to isolate the variables, and find the value of x.
This is the easy part:
Here's that equation again
90+x+(x-10)=180
Subtract 90 from both sides
90-90+x+(x-10)=180-90
x+(x-10)=90
Add 10 to both sides
x+x-10+10=90+10
x+x=100
2x=100
Divide by 2 on both sides
2x/2=100/2
x=50
There's your x value.

Hence, the perfect fifth above E₃ will have a frequency of 247.21Hz which corresponds to a B₃.
Answer: 247.215 Hz
Step-by-step explanation:
We know that in music theory, a perfect fifth is a musical interval having inverse perfect fourth that corresponds a pair of pitches with a frequency ratio of 3:2.
Let the frequency of the note a perfect fifth above [tex]E_3[/tex] be x, then we have the following proportion.
[tex]x:164.81::3:2\\\\\Rightarrow x=\dfrac{3\times164.81}{2}=247.215[/tex]

Finish the indicated multiplication and addition to obtain your final answer.
The area of the rectangle at L = 14 cm and B = 9 cm is increasing at 97 cm²/s.
What is the area of rectangle?
The area of a rectangle is given by -
A[R] = L x B
Given is the length of a rectangle is increasing at a rate of 3 cm/s and its width is increasing at a rate of 5 cm/s.
Now, we can write -
dL/dt = 3 cm/s
dB/dt = 5 cm/s
We know, that the area is -
A = LB
differentiating both sides with respect to [t], we get -
dA/dt = L dB/dt + B dL/dt
dA/dt = 5L + 3B
At L = 14 cm and B = 9 cm.
(dA/dt) [14, 9] = 5 x 14 + 3 x 9 = 70 + 27 = 97 cm²/s
Therefore, the area of the rectangle at L = 14 cm and B = 9 cm is increasing at 97 cm²/s.
