Answer: if you know the square find the GCF
Step-by-step explanation: List the prime factors of each number.
Circle every common prime factor — that is, every prime factor that's a factor of every number in the set.
Multiply all the circled numbers. The result is the GCF. Remember, the square of a number is that number times itself. The perfect squares are the squares of the whole numbers. The square root of a number, n, written below is the number that gives n when multiplied by itself.

P IS A RECTANGLE WITH A LENGTH OF 80 AND WIDTH OF X.Q IS A RECTANGLE WITHA A WIDTH OF 9.THE LENGTH OF Q IS 25 %MORE THEN THE LENGTH OF P.AREA OD Q IS 20% LESS THEN THE AREA OF P.WORK OUT THE RATIO OF X;Y
Answers
Answer:
X:Y = 3/20
Step-by-step explanation:
Given -
Length of rectangle P = 80
Width of rectangle P = X
Length of rectangle Q, Y = 25% more than the length of rectangle P
Length of rectangle Q = 1.25 X
Width of rectangle Q = 9
Area of rectangle P = 80X
Area of Q = 0.75 % of area of rectangle P
Area of Q = 0.75 * 80X = 60 X
or 9Y = 60 X
X:Y = 9/60
X:Y = 3/20

Which image shows a translation?
Answers
Answer:
The option C
Step-by-step explanation:
In the option A and B the image is been showed in either up-side down or mirror image. Only the option C has the image in a correct way and just moved the shape in a different position
The solution is Option C.
The image which shows a translation is Figure C.
What is Translation?
A translation moves a shape up, down, or from side to side, but it has no effect on its appearance. A transformation is an example of translation. A transformation is a method of changing a shape's size or position. Every point in the shape is translated in the same direction by the same amount.
Given data ,
Let the figure be represented as F
Now , the figure is translated up , down, or from side to side
The size of the figure does not change on translation
a)
The figure A has been inverted and it is not a transformation of translation
So , the Figure A is false
b)
The Figure B has been reflected by a factor , and reflection changes the coordinates of the figure F
So , Figure F is False
c)
The Figure C is translated by a factor of x to the left and y to downwards
The size of the figure remains the same
So , Figure C is a translation of Figure F
Hence , the figure C is a translation

4b. Laura has a 12-foot ladder. The safety instructions recommend the
base of the ladder be placed 4 feet from the base of the wall. How highwill the ladder be able to reach on the wall? WRITE YOUR ANSWER AS A SIMPLIFIED RADICAL. (HINT: Use the abbreviation sqrt to mean "square root of." For example an answer might look like 5sqrt3, and be read "five times the square root of 3".)
Answers
Answer:
8√2 feet
Step-by-step explanation:
We solve the above question using the Pythagoras theorem
Laura has a 12-foot ladder. The safety instructions recommend the
base of the ladder be placed 4 feet from the base of the wall.
Hypotenuse² = Opposite ² + Adjacent ²
Hypotenuse = 12ft
Adjacent = 4ft
Opposite = Height = x
Opposite ² = Hypotenuse ² - Adjacent
Opposite = √Hypotenuse ² - Adjacent
Opposite = √12² - 4²
Opposite = √144 - 16
Opposite = √128
Opposite = √64 × 2
Opposite = 8√2 feet
Therefore, the ladder will be 8√2 feet high on the wall

What is the right triangle?A right triangle is defined as a triangle in which one angle is a right angle or two sides are perpendicular.
A boat leaves the dock and travels 7 miles due south, then 24 miles due west which is given in the question.
According to Pythagoras's theorem,
In a right-angled triangle, "the square of the hypotenuse is equal to the sum of the squares of the other two sides."
perpendicular²+base²=hypotenuse²
The hypotenuse = c
Here , perpendicular = 7 and base = 24
⇒ 24² + 7² = c²
⇒ 576 + 49 = c²
⇒ 625 = c²
⇒ c² = 625
⇒ c = 25
Therefore, the boat is a distance of 25 miles far away from the dock.

Find the magnitude and direction angle of the resultant vector.
7) First vector: (8,240°)
Second vector: (10, 80°)
Answers
9514 1404 393
Answer:
3.694∠127.8°
Step-by-step explanation:
A suitable calculator makes short work of this.
(8; 240°) +(10; 80°) ≈ (3.694; 127.8°)
_____
If you like, you can add the components of the vectors and figure the magnitude and direction of the result.
a = 8(cos(240°), sin(240°)) ≈ (-4.0000, -6.9282)
b = 10(cos(80°), sin(80°)) ≈ (-1.7365, 9.8481)
r = a + b ≈ (-2.2635, 2.9199)
|r| = √(2.2635² +2.9199²) ≈ 3.69448
∠r = arctan(2.9199/-2.2635) ≈ 127.783°
The resultant is approximately 3.694∠127.78°.
Esme earns a net salary of $2,400 per month. She already has a savings account that has $100 in it. After paying her expenses every month, she'll be able to add $100 to her savings account. Esme also plans to purchase a car priced at $20,000 using a no-interest loan. She will make a $300 payment on the loan every month. In how many months will Esme have enough money saved to pay off her loan completely?
Answers
Answer:
She will be able to pay off her loan completely in approximately 50 months
Step-by-step explanation:
The amount Esme earns as net salary = $2,400
The amount she already has in a savings account = $100
The amount she would be able to add to her savings account every month = $100
The cost of the car Esme plans to purchase on the no interest loan, A = $20,000
The amount she will make as payment on the loan every month, P = $300 per month
Let 'x' represent the number of month Esme will be able to pay off her loan completely, we have
The number of month Esme will have enough money to pay off her loan completely is given by the following equation;
20,000 = 100 + 300 × x + 100 × x = 100 + 400·x
∴ x = (20,000 - 100)/400 = 49.75
Therefore, the number of months she will be able to pay off her loan completely = 49.75 months ≈ 50 months.

What is the diameter of a hemisphere with a volume of 85962 ft^3, to the nearest
tenth of a foot?
Answers
Answer: D= 69.0
Step-by-step explanation: Recall that the volume of a sphere is V = (4/3)πr^3
A hemisphere is half of a sphere, so the volume of a hemisphere is V = (1/2)(4/3)πr^3 or V = (2/3)πr^3
Now we can plug in the volume given to us by the problem to solve for the radius r
V = (2/3)πr^3
85962 = (2/3)πr^3
Use your calculator to multiply by 3, divide by 2π, and take the cube root to find r.
r ≈ 34.4947
The diameter is twice the radius, so
d ≈ 69.0
