Answer:
1728
Step-by-step explanation:
1200 borrowed for 2 years at 20% compounded annually ;
Using the compound interest formula :
A = P(1 + r/n)^nt
P = 1200 = principal
Time, t = 2 years
Rate, r = 20% = 0.2
A = 1200(1 + 0.2)^2
A = 1200(1.2)^2
A = 1200 * 1.44
A = 1728
Final amount to be repayed = 1728
x2-7x+12byx-3 divide of algebraic expression
Answer:
x - 4
Step-by-step explanation:
Please write X2-7x+12 by x-3 as x^2 - 7x + 12. The " ^ " represents exponentiation.
Notice that x^2 - 7x + 12 factors as follows: (x - 3)(x - 4), and so the original division problem
x^2 - 7x + 12 (x - 3)(x - 4)
-------------------- becomes -------------------- = x - 4
x - 3 x - 3
for all x except x = 3 (because we cannot divide by zero).

HELP ASAP!! PLEASE!! Which ordered pair is not a solution to the equation y = 6.15 + x?
A) (2.41, 8.56). B) (6.09. 12.24). C) (9.72, 15.87). D) (12.42, 18.09)
Answer: D (12.42, 18.09)
Explanation:
For A, if you substitute them, 6.15+2.41(x because x always is first), you get 8.56 but y is 8.56. So therefore, A is wrong cause it is a solution but it asks us for an incorrect solution.
For B, if you substitute the numbers, 6.09+6.15 = 12.24 but y is 12.24 meaning 12.24 = 12.24 which is true. But the question asks us which is not true/a solution, so therefore, B is also wrong.
For C, if you substitute the numbers, you get 9.72+6.15 which is 15.87. Since y is 15.87, the substituted question is 15.87=15.87 which is true and therefore, C is also wrong since it is true but it is asking us for an incorrect solution.
We are then left with D, which is the correct option. I'm guessing you want an explanation for why it is correct. So if you substitute the numbers, you would get y = 12.42+6.15 and 12.42+6.15 is 18.57 but y is 18.09. So the equation is 18.09 = 18.57 which doesn't make sense and is false. Thus, D is the correct answer because it provides a set of numbers that is a false solution to the equation.
REMEMBER:
In an ordered pair, x is the first number while y is the second, so make sure you substitute correctly!

What is the measure of angle D
Answer:
52 degrees
Step-by-step explanation:
A triangle's angles all add up to 180 degrees so we can create this equation:
x + 20 + 3x + 32 = 180
Combine like terms.
x + 3x + 20 + 32 = 180
4x + 52 = 180
Subtract 52 from both sides.
4x = 128
Divide.
128 / 4 = 32
x = 32
Plug in the value of x.
x + 20
32 + 20
52
Angle D is equal to 52 degrees.

Two highways meet at right angles in a town. Both highways are exactly straight
lines. Two cars leave the intersection at exactly the same time. One car starts traveling East
at 40mph and is decelerating at a rate of 1mph per hour. The other car starts traveling North
at 30mph and is accelerating at a rate of 0.5mph. At what rate is the distance between them
increasing 4 hours after they leave the intersection?
Answer:
Step-by-step explanation:
Using the relation :
S = ut + 1/2at²
S = distance
Car A :
Initial speed, u = 40 mph
a = negative acceleration = - 1 mph
At time, t = 4
S = 40(4) - 0.5(1)(4²)
S = 160 - 8
S = 152 miles
Car B :
Initial speed, u = 30 mph
a = acceleration = 0.5 mph
S = 30(4) - 0.5(1)(4²)
S = 120 - 8
S = 118 m
Change in distance / time
Rate of change = (152 - 118)m / 4 hours
Rate of change = 34 mi / 4 hr
Rate of change = 8.5 miles per hour

Answer:
x = 5
Step-by-step explanation:
Since both triangles are similar hence;
m<CAB = m<CDE
Given theta
m<CAB = 50degrees
m<CDE = 10x
Substitute the given angles
50 = 10x
Swap
10x = 50
Divide both sides by 10
10x/10 = 50/10
x = 5
Hence the value of x is 5

What is the greatest common factor of 18, 24, and 40?
Answer:
The factors of 18 are: 1, 2, 3, 6, 9, 18
The factors of 24 are: 1, 2, 3, 4, 6, 8, 12, 24
The factors of 40 are: 1, 2, 4, 5, 8, 10, 20, 40
Then the greatest common factor is 2.
The greatest common factor of 18 , 24 and 40 is HCF = 2
What is HCF and LCM?The Greatest Common Divisor GCF or the Highest Common Factor HCF is the highest number that divides exactly into two or more numbers. It is also expressed as GCF or HCF
Least Common Multiple (LCM) is a method to find the smallest common multiple between any two or more numbers. A common multiple is a number which is a multiple of two or more numbers
Product of HCF x LCM = product of two numbers
Given data ,
Let the HCF be represented as H
Let the first number be represented as p
Now , the value of p = 18
Let the second number be represented as q
Now , the value of q = 24
Let the third number be represented as r
Now , the value of r = 40
And , the factors of 18 = 1, 2, 3, 6, 9 and 18
The factors of 24 = 1, 2, 3, 4, 6, 8, 12 and 24
The factors of 40 = 1, 2, 4, 5, 8, 10, 20 and 40
So , the HCF of 18 , 24 and 40 is the number 2
Hence , the HCF is 2

Answer:
x=7.5
Step-by-step explanation:
first find the hypotenuse of the first right angles triangle a^2+b^2=c^2. 4^2+3^2=squareroot 25 (5)that 5 is the height of the second right angled triangle thus c^2-a^2=b^2. 9^2-5^2= 56 (squareroot is 7.48) round off 7.48 to the nearest tenth which is 7.5 since the hundredths value is more than 5hence answer is 7.5Fannie is making a rectangular blanket. The length of the blanket is 10 inches greater than its width, w, in inches. Write the function, f(w), that describes the area, in square inches, of Fannie's blanket as a function of the width, w
Answer:
The function f(w) = w²+ 10w gives the area of the rectangular blanket.
It can be written as
f(w) = (w+10) w.
Step-by-step explanation:
Let the width of the rectangular blanket be given by w and the length be given by l. According to the given condition length = 10+ width
Area of the rectangular blanket= length * width
A= l*w ( as l= w+10)
A = (w+10) w
A= w²+ 10w
The function f(w) = w²+ 10w gives the area of the rectangular blanket.
It can be written as
f(w) = (w+10) w.
The function f(w) = w²+ 10w gives the area of the rectangular blanket.
What is the area of a rectangle?The area of the rectangle is the product of the length and width of a rectangle.
Area of rectangle = L × W
Let the width of the rectangular blanket be given as w and the length be given by l.
The length is given as 10 inches greater than its width
length = 10+ width
Area of the rectangular blanket= length × width
A= l × w
also, A = (w+10) w
A= w²+ 10w
Therefore, the function f(w) = w²+ 10w gives the area of the rectangular blanket.
