4) From 11:00 AM to 4 PM, a whale's elevation changed from -60 meters to-105
meters. If the whale's elevation continues changing at a constant rate, at what time
was the whale's elevation -213 meters?
Answer:
Step-by-step explanation: It sinks 45 metres every time, so you would keep adding 45 until you got to 195, which would need 18 to finish. 18 would equate to around 1.5 hours, so around 3:30 am ish.

The clock shows the time that Ron left his home in the morning. He came home 7
hours and 35 minutes later. What time did Ron come home?
Answer: 14:35 hrs
Step-by-step explanation:
Missing time that Ron left was 07:00 hrs
Ron left the house at 07:00 hrs. If he arrived back to the house 7 hours and 35 minutes later, you can find out what time he arrived by simply adding the time he left to the time he stayed outside:
= 7 + 7hrs 35 minutes
= 14 hrs 35 minutes
= 14:35 hrs

Suppose your school costs for this term were $4780 and financial aid covered 3/4 of that amount. How much did financial aid cover? How much do you still have to pay?
Answer: Amount covered by financial aid=$3,585
Amount left that you have to pay =$1,195
Step-by-step explanation:
School cost for the term = $4780
Amount covered by financial aid = 3/4 of $4780
= 3/4 x 4780
Amount left that you have to pay=School cost for the term -Amount covered by financial aid
= $4,780 - $3,585
Amount left that you have to pay =$1,195

A circular oil spill has a radius of 2 miles. After a day, the radius of the oil spill increases by 3 miles. By how many square miles does the area of the oil spill increase? Round to the nearest thousandth, if necessary.
Answer:
65.974 Square-miles
Step-by-step explanation:
We do 3.14*2^2=12.566
We then do 3.14*5^2=78.54
78.54-12.566=65.974
The change in the area of the circular oil spill is given by the equation
A = 65.973 miles²
What is a Circle?A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “center”. Every line that passes through the circle forms the line of reflection symmetry. Also, the circle has rotational symmetry around the center for every angle
The perimeter of circle = 2πr
The area of the circle = πr²
where r is the radius of the circle
The standard form of a circle is
( x - h )² + ( y - k )² = r²,
where r is the radius of the circle and (h,k) is the center of the circle
Given data ,
Let the change in area of circular oil spill be A
Now , the equation will be
The initial radius of the circular oil spill r = 2 miles
The increased radius of the circular oil spill R = r + 3
R = 5 miles
Now , the initial area of the circular oil spill = πr²
Substituting the values in the equation , we get
The initial area of the circular oil spill = 4π miles²
Now ,
The increased area of the circular oil spill = πR²
Substituting the values in the equation , we get
The increased area of the circular oil spill = 25π miles²
And , change in area of circular oil spill A = 25π miles² - 4π miles²
On simplifying the equation , we get
The change in area of circular oil spill A = 21π miles²
The change in area of circular oil spill A = 65.973 miles²
Therefore , the value of A is 65.973 miles²
Hence , the change in circular area is 65.973 miles²

Find the value of x and y,
Can someone help???
Answer:
x is 30° and y is 20°.
Step-by-step explanation:
In an equilateral triangle all the angles form 60°.
1) 2x = 60
x = 60/2
x = 30°.
2) 3y = 60
y = 60/3
y = 20°.
x is 30° and y is 20°.
Answer:
y=20
x=30
Step-by-step explanation:
All the angles in an equilateral triangle is equal to 60 degrees. Knowing this, we can set up the following equations:
3y=60
2x=60
3y=60
Divide both sides by 3
3y/3=60/3
y=20
2x=60
Divide both sides by 2
2x/2=60/2
x=30

How do you find the area of the shaded sector of the circle? The radius is 10in and the sector is 45 degrees
Given:
Radius of the circle = 10 in
Central angle of the sector = 45 degrees
To find:
The area of the sector.
Solution:
Area of a sector is
[tex]A=\dfrac{\theta}{360^\circ}\pi r^2[/tex]
Where, [tex]\theta[/tex] is the central angle in degrees.
Putting r=10 and [tex]\theta=45^\circ[/tex], we get
[tex]A=\dfrac{45^\circ}{360^\circ}\pi (10)^2[/tex]
[tex]A=\dfrac{1}{8}\pi (100)[/tex]
[tex]A=12.5\pi[/tex]
Therefore, the area of the sector is 12.5π sq. inches.

- 2x2 + 5y2 + xy - 6x +9y
- 5x2 + 5y2 + xy + 3x + 9y
- 5x2 + 5y2 + xy - 6x + 9y
Note: In option A, it should be "+" instead of "(".
Given:
The expression is
[tex]-2x(x+y-3)+3(-x+4y)+y(3x+5y-3)[/tex]
To find:
The equivalent expression.
Solution:
We have,
[tex]-2x(x+y-3)+3(-x+4y)+y(3x+5y-3)[/tex]
Using distributive property, we get
[tex]=-2x(x)-2x(y)-2x(-3)+3(-x)+3(4y)+y(3x)+y(5y)+y(-3)[/tex]
[tex]=-2x^2-2xy+6x-3x+12y+3xy+5y^2-3y[/tex]
On combining like terms, we get
[tex]=-2x^2+5y^2+(-2xy+3xy)+(6x-3x)+(12y-3y)[/tex]
[tex]=-2x^2+5y^2+xy+3x+9y[/tex]
The expression [tex]-2x^2+5y^2+xy+3x+9y[/tex] is equivalent to the given expression.
Therefore, the correct option is A.
