The lengths of the diagonals of a rhombus are 2x and 10x. What expression gives the perimeter of the rhombus?
A. 42
B.
196
Answer:
[tex]P=4x\sqrt{26}\ units[/tex]
Step-by-step explanation:
we know that
The sides of a rhombus are all congruent and the diagonals are perpendicular bisectors of each other
so
Applying the Pythagorean Theorem
[tex]c^2=a^2+b^2[/tex]
where
c is the length side of the rhombus
a and b are the semi-diagonals
we have
[tex]a=2x/2=x\ units\\b=10x/2=5x\ units[/tex]
substitute the values
[tex]c^2=x^2+(5x)^2[/tex]
[tex]c^2=26x^2[/tex]
[tex]c=x\sqrt{26}\ units[/tex]
To find out the perimeter of the rhombus multiply the length side by 4
[tex]P=(4)(x\sqrt{26})[/tex]
[tex]P=4x\sqrt{26}\ units[/tex]
What is the slope of the line passing through the point 3,5 and -1,7
Answer:
m = -1/2
Step-by-step explanation:
As we move from the point (-1, 7) to the point (3, 5), x increases by 4 (this is the "run") and y decreases by 2 (this is the "rise").
Thus, the slope of the line connecting these two points is
m = rise / run = -2/4, or m = -1/2.
Answer:
1/2
Step-by-step explanation:
Name two coordinates that are on the line: [tex]y = 12[/tex]
Name two coordinates that are on the line: [tex]x = -5[/tex]
Answer:
(1,12) and (2,12).
(- 5,1) and (- 5, 2).
Step-by-step explanation:
y = 12 is a line that is parallel to the x-axis and at a constant distance of 12 units above the x-axis. Therefore, the points on the line will have any x-coordinate but have a constant y-coordinate i.e. 12.
Therefore, the two points on the line y = 12 can be (1,12) and (2,12).
x = - 5 is a line that is parallel to the y-axis and at a constant distance of 5 units left of the y-axis. Therefore, the points on the line will have any y-coordinate but have a constant x-coordinate i.e. - 5.
Therefore, the two points on the line x = - 5 can be (- 5,1) and (- 5, 2). (Answer)

6 ins
3
in.
5
in
8 in
Option A
Volume of bed is [tex]2\frac{2}{3}[/tex] cubic inches
Solution:
Given are the dimensions of bed
To find: volume of bed
Since bed is generally of cuboid shape, we can use the volume of cuboid formula
volume of cuboid is given as:
[tex]\text{ volume of cuboid } = l \times w \times h[/tex]
Where, "l" is the length and "w" is the width and "h" is the height of cuboid
From attached figure in question
[tex]l = 2\frac{2}{3} inches = \frac{3 \times 2 + 2}{3} = \frac{8}{3} inches[/tex]
[tex]w = 3 inches[/tex]
[tex]h = \frac{1}{3} inches[/tex]
Substituting the values in formula,
[tex]v = \frac{8}{3} \times 3 \times \frac{1}{3}\\\\v = \frac{8}{3} = 2\frac{2}{3}[/tex]
Therefore volume of bed is [tex]2\frac{2}{3}[/tex] cubic inches
A camping leader bought the items listed in the table for his team. What is the average cost of an item in his purchase?
A. $7.75
B.$7.58
C.$6.60
D.$5.44
The right answer is Option D: $5.44
Step-by-step explanation:
Given,
Cost of one sun visor = $6.25
Cost of 11 sun visors = 6.25*11 = $68.75
Cost of one sunglasses = $8.90
Cost of 4 sunglasses = 8.90*4 = $35.60
Cost of one water bottle = $9.50
Cost of 8 water bottles = 9.50*8 = $76
Cost of one whistle = $1.75
Cost of 15 whistles = 1.75*15 = $26.25
Total number of items = 11+4+8+15 = 38
Total cost of items = 68.75+35.60+76+26.25 = $206.60
Average = [tex]\frac{Sum\ of\ prices}{No.\ of\ items}[/tex]
[tex]Average=\frac{206.60}{38}\\Average=\$5.436[/tex]

Which of the following shows that polynomials are closed under subtraction when two polynomials, (5x2 + 2x − 6) − (3x2 − 6x + 2), are subtracted?
2x2 − 4x − 4; will be a polynomial
2x2 − 4x − 4; may or may not be a polynomial
2x2 + 8x − 8; will be a polynomial
2x2 + 8x − 8; may or may not be a polynomial
Answer:
For [tex](2x^2 + 8x - 8)[/tex], the group is CLOSED as it a polynomial.
Step-by-step explanation:
Here, the given polynomials are:
[tex]P(x)=(5x^2+2x-6)\\Q(x)=(3x^2-6x+2)[/tex]
Now, a group G is said to be CLOSED UNDER SUBTRACTION if,
a and b are he elements of G ⇒ (a-b) is ALSO AN ELEMENT of G
Now, here:
[tex]R(x) = P(x) - Q(x) = (5x^2+2x-6) - (3x^2-6x+2) = (2x^2 + 8x - 8)[/tex]
or, [tex]R(x) = (2x^2 + 8x - 8)[/tex]
Also, R(x) is a POLYNOMIAL.
So, R(x) is an Element of group G.
So, the set G of polynomials.
Hence, for the polynomial [tex](2x^2 + 8x - 8)[/tex], it will be a polynomial the group is CLOSED.

Andre is working from home to a festival that is 1 5/8 km away. He takes a quick rest after walking 1/3 km what fraction of the trip has Andre completed
Answer:
The fraction of trip completed by Andre is [tex]\frac{31}{24}[/tex] km
Step-by-step explanation:
Given as :
The Total distance between the home to a festival = 1 [tex]\frac{5}{8}[/tex] km
I.e The total distance between the home to a festival = [tex]\frac{13}{8}[/tex] km
The distance cover by Andre before taking rest = [tex]\frac{1}{3}[/tex] km
Let The fraction of trip completed by Andre = x km
So, According to question
The fraction of trip completed by Andre = The Total distance between the home to a festival - The distance cover by Andre before taking rest
or, x = [tex]\frac{13}{8}[/tex] km - [tex]\frac{1}{3}[/tex] km
or, x = [tex]\frac{39 - 8}{24}[/tex] km
∴ x = [tex]\frac{31}{24}[/tex] km
Or, The fraction of trip completed by Andre = x = [tex]\frac{31}{24}[/tex] km
Hence , The fraction of trip completed by Andre is [tex]\frac{31}{24}[/tex] km Answer
Answer:
[tex]\frac{4}{15}[/tex]
Step-by-step explanation:
We know that the total distance is
[tex]1\frac{5}{8}km[/tex] which is standard fraction would be [tex]\frac{13}{8}km[/tex].
So, Andre walks [tex]\frac{1}{3}km[/tex], that means he needs to walk the following distance to get to the festival
[tex]\frac{13}{8}-\frac{1}{3}=\frac{39-8}{24}=\frac{31}{24}km[/tex]
Now, to find the fraction of the tripe that represents the distance he already completed, we have to divide
[tex]\frac{1}{3} \div \frac{13}{8}=\frac{1}{3} \times \frac{8}{13}=\frac{8}{30}=\frac{4}{15}[/tex]
Therefore, we completed a [tex]\frac{4}{15}[/tex] part of the total distance.

Answer:
Neither
Step-by-step explanation:
Can be determined because there is enough information (Length, width, and height).
Not congruent because from the picture itself, the figures are in different sizes.
Not similar because:

A line passes through the point (-8,8) and has a slope of -3/2. Write an equation in point-slope form for a this line.
Answer:
y-8=-3/2(x+8)
Step-by-step explanation:
y-y1=m(x-x1)
y-8=-3/2(x-(-8))
y-8=-3/2(x+8)
Final answer:
The equation of the line in the point-slope form that passes through (-8, 8) with a slope of -3/2 is y - 8 = (-3/2)(x + 8).
Explanation:
To write an equation in point-slope form for a line that passes through a given point with a known slope, we use the formula y - y1 = m(x - x1), where (x1, y1) is the point the line passes through and m is the slope of the line.
For the line that passes through the point (-8, 8) with a slope of -3/2, we substitute these values into the point-slope form equation:
y - 8 = (-3/2)(x + 8)
This equation represents the specific line asked in the problem.
Which would you rather have: 21% of $3,876 or 17% of $4,552? choose an inequality sign.
Step-by-step explanation:
21 percent of 3,876 is 813.96$, and 17 percent of 4552 is 773.67$. 813.96>773.67
21% of $3,876 is $813.96, while 17% of $4,552 is $773.84. Therefore, 21% of $3,876 inequality sign is greater than 17% of $4,552.
Explanation:Choosing between 21% of $3,876 or 17% of $4,552 involves calculating each percentage of the given amounts to compare which is greater. To do this:
Calculate 21% of $3,876: 0.21 × 3876 = $813.96.
Calculate 17% of $4,552: 0.17 × 4552 = $773.84.
Comparing these two amounts using an inequality sign, we see that $813.96 is greater than $773.84. So, you would rather have 21% of $3,876 than 17% of $4,552.

Answer:
[tex]y=1500\cdot(0.902)^T[/tex]
Step-by-step explanation:
Let T be the number of years since the start of the study and y be the area that the forest covers in [tex]\text{km}^2[/tex].
We have been given that at the beginning of an environmental study a forest cover an area of 1500 [tex]\text{km}^2[/tex]. Since then this area has decreased by 9.8% each year.
We know that an exponential function is in form [tex]y=a\cdot(1-r)^x[/tex], where,
y = Final amount,
a = Initial amount,
r = Decay rate in decimal form,
x = Time.
Let us convert 9.8% into decimal as:
[tex]9.8\%=\frac{9.8}{100}=0.098[/tex]
We have been given that initial value (a) is [tex]1500[/tex].
Upon substituting our given values, we will get:
[tex]y=1500\cdot(1-0.098)^T[/tex]
[tex]y=1500\cdot(0.902)^T[/tex]
Therefore, our required exponential function would be [tex]y=1500\cdot(0.902)^T[/tex].

Answer:
The coordinates of the mid-point are :
[tex](\frac{1}{2}, \frac{5}{2})[/tex]
Step-by-step explanation:
We know that, the coordinates of the mid-point (x, y) of a line segment joining the points (x₁, y₁) and (x₂, y₂) is given by
[tex](x, y) = (\frac{x_{1} +x_{2} }{2},\frac{y_{1}+y_{2} }{2} )[/tex]
Now, we have the given points as (3, 5) and (-2, 0).
By using the above formula, coordinates of the mid-point (x, y) of the line-segment joining the points (3, 5) and (-2, 0) is given by,
[tex]x = \frac{3+(-2)}{2} = \frac{3-2}{2} = \frac{1}{2}[/tex]
[tex]y = \frac{5+0}{2} = \frac{5}{2}[/tex]
∴ coordinates of the mid-point of the line-segment joining the points (3,5) and (-2,0) is [tex](\frac{1}{2}, \frac{5}{2})[/tex].
