Answer:
The answer is 1 5/12 or 17/12.
Step-by-step explanation:
First we turn 5 2/3 into a Improper fraction.
5 2/3 = 17/3
Next we change 4 to 1/4 then multiply 1/4 by 17/3.
17/3 * 1/4 = 17/12
17/12 = 1 5/12
Hope this helps! :)
Answer:

5[tex]\frac{2}{3}[/tex] / 4 = [tex]\frac{17}{3}[/tex] / [tex]\frac{4}{1}[/tex] = [tex]\frac{17}{3}[/tex] * [tex]\frac{1}{4}[/tex] = 17/12
Which ratio represents the cotangent of angle B in the right triangle below?
A. 5/3
B. 3/5
C. 3/4
D. 4/3
Answer:
C. 3/4
Step-by-step explanation:
Using the SOH CAH TOA identity;
tan theta = opposite/adjacent
From the diagram
Opposite = x
Adjacent = 12
tan <B = x/12
Since cot <B = 1/tan <B
cot <B = 12/x
Get x using pythagoras theorem
x² = 20²-12²
x² = 400 -144
x² = 256
x = 16
Hence cot <B = 12/16
cot <B =3/4

A gardener has 60 feet of fencing to keep
animals out of the garden. Find the LARGEST
AREA of garden that this fence will enclose.
Answer:
225 ft^2
Step-by-step explanation:
From what we have in the question, we have 60 ft of fencing
To maximize the area, we will need to have a square
For a square, the length of all sides are equal
Let us call one of the sides s
Thus, from the perimeter of the square;
4s = 60
s = 60/4
s = 15 ft
The area is thus, the product of the side length of the square
15 * 15 = 225 ft^2
At the end of the year, cars made in the current year are marked down to make room for
next year's models. One particular model had a sticker price of $45,160 when it was new. It
has just been marked down by 5%. What is the sale price of the vehicle?
Answer:
The sale price of the vehicle is $36885
Step-by-step explanation:
One particular model had a sticker price of $49,180 when it was new. This means that the initial cost of the car was $49,180. It has just been marked down by 25%. This means the initial price of the car was reduced by an amount. The amount by which the initial price of the car was reduced would be
25/100 × 49180 = 0.25 × 49180 = $12295.
The sale price of the vehicle would be
49180 - 12295 = $36885
Aiku has one piece of rope that is 45 centimeters long and another that is 367 centimeters long.
How many meters of rope does Aiku have in all?
0.0412 m
0.412 m
4.12 m
41.2 m
Answer:
the 3rd one.
Step-by-step explanation:
Option D is correct, Aiku has a total of 4.12 meters of rope in all.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
To find the total length of the rope in meters, we need to convert the lengths of the two ropes from centimeters to meters and then add them together.
The length of the first rope is 45 centimeters, which is equal to 0.45 meters (since 1 meter = 100 centimeters).
The length of the second rope is 367 centimeters, which is equal to 3.67 meters.
Adding these two lengths together, we get:
0.45 meters + 3.67 meters = 4.12 meters
Therefore, Aiku has a total of 4.12 meters of rope in all.

A chess club with 45 members is electing a new president. Bob received 18 votes. What percentage of the club members voted for Bob?
Given:
A chess club with 45 members is electing a new president.
Bob received 18 votes.
To find:
The percentage of the club members who voted for Bob.
Solution:
We have,
Total number of members = 45
Votes received by bob = 18
Now, the percentage of the club members who voted for Bob is
[tex]\%=\dfrac{\text{Number of members voted for bob}}{\text{Total members}}\times 100[/tex]
[tex]\%=\dfrac{18}{45}\times 100[/tex]
[tex]\%=\dfrac{2}{5}\times 100[/tex]
[tex]\%=\dfrac{200}{5}[/tex]
[tex]\%=40[/tex]
Therefore, 40% of the club members voted for Bob.

a 33.4 inches
b. 35.6 inches
C. 37.5 inches
d. 39.3 inches
Answer:
d. 39.3 inches
Step-by-step explanation:
We are to find the Arc length of the circle
To solve the above question, the formula is given as:
Arc length = Central angle × radius
From the above Question, we are given:

Unit test, Part 2: Measurement of Two-Dimensional Figures Please help!!!
Answer:
Step-by-step explanation:
1. Area of the composite figure = Area of the sector + Area of rectangle
Area of sector = (θ/ 360) x [tex]\pi[/tex][tex]r^{2}[/tex]
From the figure,
θ = 30, and r = 65
Area of sector = [tex]\frac{30}{360}[/tex] x [tex]\frac{22}{7}[/tex] x 65 x 65
= 1 1065.55[tex]m^{2}[/tex]
Area of rectangle = length x width
= 65 x 4
= 260 [tex]m^{2}[/tex]
Area of the composite figure = 1 1065.55 + 260
= 11325.55
Area of the composite figure is 11326 [tex]m^{2}[/tex].

Circle sector is a section of a disk encompassed by two radii and an arc. The area of the composite figure is 29.9194 m².
What is a sector of a circle?A circular sector, also known as a circle sector or a disk sector, is a section of a disk encompassed by two radii and an arc, with the minor sector being smaller and the main sector being bigger.
[tex]\text{The area of the sector of the circle }= \pi r^2 \times \dfrac{\theta}{360^o}[/tex]
The area of the composite figure is the sum of the area of the sector of the circle and the area of the rectangle.
The area of the sector of the circle whose angle at the centre of the circle is 30°, while the radius of the circle is the length of the reactangle which is 5.5 cm.
[tex]\text{The area of the sector of the circle }= \pi r^2 \times \dfrac{\theta}{360^o}[/tex]
[tex]= \pi (5.5)^2 \times \dfrac{30}{360^o}\\\\=7.9194\rm\ m^2[/tex]
Thus, the area of the sector of the circle is 7.9194 m².
The area of the reactangle whose length is 5.5 inches while the width is 4 m.
[tex]\rm \text{Area of the rectangle} = Length \times width[/tex]
[tex]= 5.5 \times 4\\\\= 22\rm\ m^2[/tex]
Thus, the area of the rectangle is 22 m².
Now, the total area of the composite figure can be written as,
Area of the composite figure = Area of the sector of circle+Area of rectangle
Area of the composite figure = 7.9194 +22 = 29.9194 m²
Hence, the area of the composite figure is 29.9194 m².

For what values of x:
Is the trinomial x^2−11x+31 equal to 1?
are the values of the polynomials x^2−5x−3 and 2x−5 equal?
Is the binomial 7x+1 equal to the trinomial 3x^2−2x+1?
Is the trinomial −2x^2+5x+6 equal to the binomial 4x^2+5x?
Answer:
A) x = 5 or x = 6
B) x = 0.298 or 6.702
C) x = 3
D) x = ±1
Step-by-step explanation:
A) Values of x for which;
x² − 11x + 31 = 1
x² - 11x + 30 = 0
Using quadratic formula, we have;
x = 5 and x = 6
B) Values of x for which;
x² − 5x − 3 = 2x − 5
x² − 5x - 2x - 3 + 5 = 0
x² - 7x + 2 = 0
Using quadratic formula, we have;
x = 0.298 or 6.702
C) Values of x for which;
7x + 1 = 3x² − 2x + 1
3x² - 2x - 7x + 1 - 1 = 0
3x² - 9x = 0
3x² = 9x
Divide both sides by 3x to get;
x = 3
D) Values of x for which;
−2x² + 5x + 6 = 4x² + 5x
Rearranging, we have;
4x² + 2x² + 5x - 5x - 6 = 0
6x² - 6 = 0
x² = 6/6
x² = 1
x = √1
x = ±1
The values of [tex]x[/tex] for the given situations would be as follows:
A). [tex]x = 5[/tex] or [tex]x = 6[/tex].
B). [tex]x = 0.298[/tex] or [tex]6.702[/tex]
C). [tex]x = 3[/tex]
D). [tex]x =[/tex] ±[tex]1[/tex]
Find the value of xa). [tex]x^2 - 11x + 31 = 1[/tex]
⇒ [tex]x^2 - 11x + 30 = 0[/tex]
by employing the quadratic equation, we have the values of [tex]x[/tex];
Considering
a = 1
b = -11
c = 30
⇒ {[tex]-(-11)[/tex] ± [tex]\sqrt{(-11)^2 -4 .1. 30 }[/tex]}[tex]/2.1[/tex]
Now,
[tex]x =[/tex] ([tex]11[/tex] ± [tex]1)/2[/tex]
Thus, the values for which the given trinomial would be equivalent to 1 would be:
∵ [tex]x = 5[/tex] and [tex]x = 6[/tex]
b). [tex]x^2 - 5x - 3 = 2x - 5[/tex]
⇒ [tex]x^2 - 5x - 2x - 3 + 5 = 0[/tex]
⇒ [tex]x^2 - 7x + 2 = 0[/tex]
by employing the quadratic equation, we have the values of [tex]x[/tex];
Therefore, the values of polynomials [tex]x^2 - 5x - 3 = 2x - 5[/tex] when:
∵ [tex]x = 0.298[/tex] or [tex]x = 6.702[/tex]
c). [tex]7x + 1 = 3x^2 - 2x + 1[/tex]
⇒ [tex]3x^2 - 2x - 7x + 1 - 1 = 0[/tex]
⇒ [tex]3x^2 - 9x = 0[/tex]
⇒ [tex]3x^2 = 9x[/tex]
by dividing both the sides by [tex]3x[/tex] to receive;
Hence, the binomial and trinomial [tex]7x + 1 = 3x^2 - 2x + 1[/tex] when:
∵ [tex]x = 3[/tex]
d). [tex]-2x^2 + 5x + 6 = 4x^2 + 5x[/tex]
by arranging them again, we get;
[tex]4x^2 + 2x^2 + 5x - 5x - 6 = 0[/tex]
⇒ [tex]6x^2 - 6 = 0[/tex]
⇒ [tex]x^2 = 6/6[/tex]
The trinomial and binomial [tex]-2x^2 + 5x + 6 = 4x^2 + 5x[/tex] would be when:

Answer:

Step-by-step explanation:
====================================================
Explanation:
Since x and y are in a proportional relationship, this means that y = kx. This is a direct variation equation.
k is the proportionality constant
To find k, we'll use any nonzero x and y pairing. Let's say we use the second row with x = -3 and y = 1
This leads to
y = kx
y/x = k
k = y/x
k = 1/(-3)
k = -1/3
Or we could use the third row to get
k = y/x
k = 2/(-6)
k = (1*2)/(-3*2)
k = -1/3
We get the same value of k for that row as well. I'll let you check the other rows. You cannot use the first row because dividing by zero is not allowed.
Since k = -1/3, this means y = kx updates to y = (-1/3)x which matches with choice A. So effectively, whatever the x input is, we multiply that by -1/3 to get the y output.
Multiplying by -1/3 is the same as dividing by -3. This means that y = (-1/3)x is the same as y = -x/3
