Answer:
A and D
Step-by-step explanation:
Given that the area of a square = 400 units² = s²
Where s is one side length of the square.
It means that the side length (s) = √400 = 20
If the length of each side length increase by 1 units, new side length = 21 units
Area of new square = 21² = 441
The following statements would be true if the side length was increased by 1 units:
A. "The area of the square would be a rational number"
441 is a rational number, because a rational number is a quotient of two integers.
441 and 1 are two integers. Their quotient = 441. I.e. 441 ÷ 1 = 441
D. "The area of the square would be a perfect square".
A number is considered a perfect square if it can be expressed as a product of two equal integers.
441 can be expressed as 21*21

Two cruise ships left the same port. After two hours, Ship A is 30 miles west and 18 miles north of the port and Ship B is 10 miles west and 27 miles south of the port. If there is a tug boat located one-fifth of the way from Ship A to Ship B, find the location of the tug boat relative to the port.
Answer:
1.10
Step-by-step explanation:
that's your answer
The location of the tug boat relative to the port will be 30.83 miles.
What is trigonometry?Trigonometry is the branch of mathematics that set up a relationship between the sides and angles of right-angle triangles.
The distance of ship A from the port is x
X²= 18²+30²
X²= 324+900
X²=1224
X=34.9857 miles
Bearing from port:-
Tanθ= 18/30
θ = tan^-1 3/5
θ= 31°
N 31° E
The distance of ship B from the port is y.
Y²= 27²+10²
Y²= 729+100
Y²= 829
Y=28.7924 miles
Bearing from port:-
Tanθ = 2.2
θ = 69.7°
90-69.7= 20.3
N 20.3°W
The distance between the two ships is z.
Z²=34.9857²+28.7924²-2(24.9857)(28.7924)cos(31+69.7°)
Z²= 2053+267.1
Z²= 2320.1
Z=48.18 miles
One-fifth of 48.18
=9.63 miles
The distance of the boat is D.
D/sin 60 = 34.9857/sin 100.7
D=30.83 miles
Therefore, the location of the tug boat relative to the port will be 30.83 miles.

An emu that measures 22 inches in height is 14 inches less than 2 times the height of a stuffed toy canary. What is the height of the stuffed toy canary? Jesus thinks the height of the canary is 18 inches. Is this true or false?
Answer: The height of the stuffed toy canary is 18 inches so Jesus is right.
Step-by-step explanation:
We can represent the first statement by the equation 22= 2x - 14 where x is the height of the stuffed toy canary so solve for x
22 = 2x -14 Add 14 to both sides
+14 +14
36 = 2x Divide both sides by 2
x = 18
Jesus is right.

Solve each system of equations of equations.
x + y = -6
2x - y = 3
Answer:
x = -1, y = -5
Step-by-step explanation:
x + y = -6
2x - y = 3
Add the two equations together to eliminate y
x + y = -6
2x - y = 3
------------------
3x = -3
Divide by 3
3x/3 = -3/3
x = -1
Now find y
x+y = -6
-1+y = -6
Add 1 to each side
-1+1 +y = -6+1
y = -5
Solve for r:
B=dPIEr^2
Answer:
C
Step-by-step explanation:
So we have the equation:
[tex]B=d\pi r^2[/tex]
And we want to solve for r.
So first, isolate the r variable. Divide both sides by dπ. So:
[tex]\frac{B}{d\pi}=\frac{d\pi r^2}{d\pi}[/tex]
The right side cancels:
[tex]\frac{B}{d\pi}=r^2[/tex]
Take the square root of both sides:
[tex]r=\sqrt\frac{B}{d\pi}[/tex]
We can rearrange the terms:
[tex]r=\sqrt\frac{B}{\pi d}[/tex]
Our answer is C.

7x-5y=2
Answer:
y = (7x-2)/5Step-by-step explanation:
Given the expression 7x-5y = 2, we are to write y in terms of x. to do that, we will have to make y the subject of the formula from the given expression as shown;
7x-5y = 2
subtract 7x from both sides of the equation
7x-5y-7x = 2-7x
-5y = 2-7x
Multiply through by minus sign
-(-5y) = -(2-7x)
5y = -2+7x
5y = 7x-2
Divide both side by 5;
5y/5 = (7x-2)/5
y = (7x-2)/5
Hence the expression y as a function of x is given as y = (7x-2)/5
