In rhombus ABCD, AB=12 and AC=22. Find the area of the rhombus to the nearest 10.
a) 195
b) 221.3
c) 105.5
d) 100.8
Answer:
c) 105.5 square units
Step-by-step explanation:
The area of a rhombus can be computed as half the product of the diagonal lengths.
__
Half the diagonal BD will be one leg of the right triangle formed by the diagonals and the sides of the rhombus. The length of that leg is found using the Pythagorean theorem:
a² +b² = c²
11² +b² = 12²
b² = 144 -121 = 23
b = √23 ≈ 4.796
This value is half the length of diagonal BD, so multiplying it by the length of diagonal AC will give the area of the rhombus.
Area = 1/2(AC)(BD) = (22)(4.796) ≈ 105.5 . . . . square units

Answer:
x=2, y=-4
Step-by-step explanation:
If you put a vertical or horizontal line straight through the shape and it looks the same, then it is symmetrical. You can put a symmetrical line both vertically AND horizontally. To do this, you just need a line going through the points at the tips and the points at the sides of the quadrilateral. A line that is vertical will be an x=, because it only covers one x-value. So, the line for x will be x=2, because it goes through both tips of the quadrilateral. A horizontal line will be y= because it only covers one y-value. So, the line for the horizontal line will by y=-4, because this goes through both sides of the quadrilateral.

Step-by-step explanation:
How does the slope of g(x) compare to the slope of f(x)? the slope of g(x) is the opposite of the slope of f(x). the slope of g(x) is less than the slope of f(x). the slope of g(x) is greater than the slope of f(x). the slope of g(x) is equal to the slope of f(x).
The statement that correctly compares the slopes of the linear functions is: the slope of g(x) is less than the slope of f(x).
How to Find Slope of a Linear Function?Slope of a linear function = change in y / change in x = rise/run
Given the linear functions, g(x) and f(x) as shown in the image attached:
Slope of g(x) = 1/2 = 0.5
Slope of f(x) = 2/1 = 2
Therefore, we can conclude that: the slope of g(x) is less than the slope of f(x).

What is the approximate length of arc s on the circle below? use 3.14 for pi. round your answer to the nearest tenth. a circle is shown. 2 rays form an angle of 45 degrees. the length of the rays is 8 inches. arc s contains the angle measuring 45 degrees. 5.6 in. 6.3 in. 14.3 in. 25.1 in.
The length of an arc with central angle of 45 degrees and radius of 8 inches is 6.3 inches.
How to find length of an arc?length of an arc = ∅ / 360 × 2πr
where
∅ = central angler = radiusHence,
r = 8 inches

What’s the volume of the figure below
Answer:
41.89 cm3
Step-by-step explanation:
Given : Height = 10 cm
Given: Radius = 2 cm
Find the volume,
The formula for volume is,
V = π([tex]r^2[/tex])[tex]\frac{h}{3}[/tex]
Fill in the formula with the given values,
π · [tex]2^2[/tex] · [tex]\frac{10}{3}[/tex]
= 41.8879.....
Round answer to the nearest hundredth,
(The Rule For Rounding: the last digit is less than 5, keep the previous digit the same. If it's 5 or more then you should round the previous digit up.)
41.8879
7 is more than 5 so bring the 8 up to a 9,

division equation where 13 is quotient with the dividend a whole number and a unit fraction is the divisor
The division equation that satisfies the required parameters where 13 is the quotient is 1/1/13 = 13
How to determine the equation?The given parameters are:
Quotient = 13Dividend = Whole numberDivisor = Unit fractionA division equation is represented as:
Dividend/Divisor = Quotient
Substitute Quotient = 13
Dividend/Divisor = 13
A unit fraction is represented as 1/n, where n is an integer.
So, the divisor can be represented as 1/13
Dividend/1/13 = 13
Divide both sides by 13
Dividend = 1
So, we have:
1/1/13 = 13

A chef has two dozen meatballs to add to a pot of sauce. Each meatball has a two-inch diameter. Before the meatballs are added, the sauce is 2 inches from the top of the 14-inch diameter pot. Will the sauce spill over when the chef adds the meatballs to the pot? Show all of your work to justify your answer.
Given the volume of the space in the pot and the volume of the meatballs, the sauce will not spill over.
Will the sauce spill over?
The first step is to determine the volume of the remaining space that the sauce is yet to fill. A pot usually has the shape of a cylinder, so the formula for the volume of a cylinder would be used.
Volume of a cylinder = πr²h
π x (14/2)³ x 2 = 98 in³
The second step is to determine the volume of the two dozen meatballs.
Volume of a sphere = 4/3πr³
24 x (4/3 x π x (2/2)³) = 32π in³

The sauce will spill over if the volume of the pot is less than 146π in³ and it will not spill over if the volume of the pot is more than 146π in³.
Volume of the sauce in the potThe volume of sauce in the pot is calculated as follows;
V = πr²h
V = π x (7)² x (2)
V = 98π in³
Volume of the two dozen meatballsArea of 1 meatball = πr² = π x (1)² = π in²
Area of the 2 dozen = (2 x 12) x A
= 24 x π in² = 24π in²
the height of each meatball = 2 in,
Volume of the 2 dozens = 2 in x 24π in² = 48π in³
Total volume of the meatball and sauce in the pot = 98π + 48π = 146π in³
Thus, the sauce will spill over if the volume of the pot is less than 146π in³ and it will not spill over if the volume of the pot is more than 146π in³.
