<em><u>Question:</u></em>
How fast should the ant walk to go around the rectangle in 4 minutes if the sides are 12 inches and 16 inches
<em><u>Answer:</u></em>
The ant should walk 14 inches per minute
<em><u>Solution:</u></em>
Given that,
Dimensions of rectangle are 12 inches and 16 inches
<em><u>Find the perimeter of rectangle</u></em>
Perimeter = 2(length + width)
Perimeter = 2(12 + 16)
Perimeter = 2(28) = 56
Thus perimeter of rectangle is 56 inches
Time taken = 4 minutes
We have to find the speed at which ant covers 56 inches in 4 minutes
<em><u>The speed is given by formula:</u></em>


Thus the ant should walk 14 inches per minute
Answer:
C) Subtraction property of equality.
Step-by-step explanation:
Given that, two lines
and
intersect to make pairs of vertical angles:
and
.
Kindly refer to the attached image for details of the given angles and lines.
Proof that
:

Here, subtraction property of equality is used in the last step shown in the above.
As per the <em>Subtraction property </em>of equality, when some value is subtracted from both the sides of the equality, equality remains the same.
The equation of the circle x² +y² – 8x – 6y + 21 = 0 is equal to the equation (x + 4)² + (y − 3)² = 2². Then the correct option is C.
<h3>What is a circle?</h3>
It is a locus of a point drawn an equidistant from the center. The distance from the center to the circumference is called the radius of the circle.
The equation of the circle is given as
x² + y² – 8x – 6y + 21 = 0
The equation can be written as
x² – 8x + 16 + y² – 6y + 9 = 4
(x + 4)² + (y − 3)² = 2²
Then the center of the circle is at (-9, 6) and the radius of the circle is 10 units.

on the bad side
For a score with a range between 300-850, a credit score of 700 or above is generally considered good. A score of 800 or above on the same range is considered to be excellent. Most credit scores fall between 600 and 750. Hope that this helps you and have a great day :)
Answer:
Length of the shorter diagonal is 8.68 cm.
Step-by-step explanation:
Length of the side AB = 11 cm
Length of side BC = 5 cm
Angle between these sides, m∠ABC = 50°
By cosine rule in ΔABC,
AC² = AB² + BC² - 2AB.BC.cos B
AC² = (11)² + 5² - 2(11)(5)cos50°
AC² = 121 + 25 - 70.71
AC = √(75.29)
AC = 8.68 cm
By the property of parallelogram,
m∠B + m∠C = 180° [Interior consecutive angles]
50° + m∠C = 180°
m∠C = 130°
Similarly, In ΔBCD,
BD² = BC² + CD² - 2BC.CD.cos130°
BD² = (5)² + (11)² - 2(5)(11)cos130°
BD² = 25 + 121 + 70.71
BD² = 216.71
BD = 14.72 cm
Therefore, length of the shorter diagonal will be 14.72 cm.
