If the length of a rectangle is decreased by 6 cm and the width is increased by 3 cm, the result will be a square, the area of which will be 27 cm^2 smaller than the area of the rectangle. Find the area of the rectangle.
Answers
Answer:
252 centimeters squared is the answer.
The area of the rectangle is 252 cm².
What is a rectangle?A rectangle is a plane shape that has pair of opposite sides and angles equal
To calculate the area of a rectangle, we use the formula below.
Formula:
Area of a rectangle(A) = Length(L)×Width(W).............. Equation 1
⇒ Let the length of the rectangle be x and the width of the rectangle be y.
If the length is decreased by 6 cm
new length = (x-6) cmAnd if the width is increased by 3 cm
new width = (y+3) cmSince the new length and the new width form a square,
Note: In a square, all sides are equal
(x-6) = (y+3)x = y+9...................... Equation 2Also, The area of the new square formed is smaller than the area of the rectangle by 27 cm²
xy = (y+3)²+27............ Equation 3Substitute these values of x in equation 2 into equation 3
(y+9)(y) = (y+3)²+27y²+9y = y²+6y+9+27y²+9y = y²+6y+36Collect like terms
y²-y²+9y-6y = 363y = 36y = 36/3y = 12 cm.Substitute the value of y into equation 1 to get x
x = 12+9x = 21 cm.Area of a rectangle = Length×width = 12×21 = 252 cm²Hence, The area of the rectangle is 252 cm².

h
w = 11.3
A. h = 7.0 inches
B. h = 12.9 inches
C. h = 10.7 inches
D. h = 9.9 inches
Answers
Given:
[tex]d = 13.3\ in[/tex]
[tex]w = 11.3\ in[/tex]
[tex]d=\sqrt{w^2+h^2}[/tex]
To find:
The value of h.
Solution:
We have,
[tex]d=\sqrt{w^2+h^2}[/tex]
Substituting [tex]d = 13.3, w = 11.3[/tex], we get
[tex]13.3=\sqrt{11.3^2+h^2}[/tex]
Taking square on both sides.
[tex]176.89=127.69+h^2[/tex]
[tex]176.89-127.69=h^2[/tex]
[tex]49.2=h^2[/tex]
Taking square root on both sides, we get
[tex]\pm 7.01427=h[/tex]
[tex]h\approx \pm 7[/tex]
Height cannot be negative so [tex]h=7\ in[/tex].
Therefore, the correct option is A.

Do people who are the only child have more pets?
Would surveying only the people in your class give you enough information to answer this new question? Explain your reasoning.
Answers
Answer: t does sound logical that an only child may be more inclined to have a pet than children in larger families. However we haven’t located any statistics that support that thought.
Our own dad was a single child and did have a dog while growing up. Times were tough back in the those days 1920s to 1945 so he couldn’t have a lot of pets growing up. During WWll he adopted a dog on Siapan and smuggled her home on the ship with him when the war was over.
Growing up he always dreamed of raising dogs, but ended up raising three kids instead. The first born, a boy, loved cats but never had one of his own until he was grown up and had a place of his own. The reason he didn’t have a pet of his own as a child was because 4 years after he was born his twin sisters entered.
We hit the ground with an insatiable need to interact with animals of all kinds. Sure we had each other for companionship but some people are just born with a great need to converse with other species. From the time we entered the household all pets became ours.
As far as statistics go, they do find that families with children are more likely to have pets. It just doesn’t stipulate how many children are in the family.
One of the interesting finds though is that the percentage of childless families are increasing but pet ownership is continuing to grow as well.
Step-by-step explanation:
Answer:
Only children do have more pets because it's something to do. If your class has a mix of only children and people with siblings then you would have enough information.

A 15 ft tree casts a 9 foot shadow on the ground. What is the angle of elevation formed by the tree’s shadow and the sun? (Round to the nearest hundredth)
Answers
Answer:
59.04
Step-by-step explanation:
If you were to make a right triangle, 15 would be the altitude (height), and 9 would be the base. You need the angle of elevation which is going the angle of the hypotenuse going upwards. (Bottom Left/Right Corner.) From that angle you need to solve for arctan (Used for solving the measure of angle.) Simply plug into your calculator arctan(15/9) to get the answer.
