Bella earned $216 in interest after 4 years on a principal of $1,500. What is her interest rate?
Answer:
R = 148.6111%/year
Equation:
r = (1/t)(A/P - 1)
Calculation:
Solving our equation:
r = (1/4)((1500/216) - 1) = 1.48611111
r = 1.48611111
Converting r decimal to R a percentage
R = 1.48611111 * 100 = 148.6111%/year
The interest rate required to get a total amount, principal plus interest, of $1,500.00 from simple interest on a principal of $216.00 over 4 years is 148.6111% per year.
Answer: 3%
Step-by-step explanation:
216 / 1500 = 14.4
14.4/ 48 months = .003
.003 x 100 = 3%
Find 3 consecutive odd integers such that 10 times the first is 59 more than the third
9514 1404 393
Answer:
7, 9, 11
Step-by-step explanation:
Let x represent the middle integer. Then the first is x-2, and the third is x+2. The given relation is ...
10(x -2) = 59 +(x +2)
10x -20 = x +61 . . . . eliminate parentheses
9x = 81 . . . . . . . . . . . add 20-x
x = 9 . . . . . . . . . . . . . divide by 9
The integers are 7, 9, 11.

I NEED HELP!!
7÷7/11=
Please explain for me
Answer:
11
Step-by-step explanation:
You have to first make the 7 into a fraction (7/1) then keep, change, flip.
You keep the 7/1 as it is, you change the division sign into a multiplication sign, and you flip the 7/11 to 11/7. You then just multiply straight across to get 77/7 which is the same thing as 11/1 which is the same thing as 11!
Final answer:11

f=4x-3)²-(2x+4)²
a) factorise l'espression:
b)déduis en les solutions de l'equation: 4x-3)²-(2x+4)²=0
Answer:
A)(6x+1)(2x-7)
B)x={-1/6,7/2}
Step-by-step explanation:
A) (4x-3)²-(2x+4)²
(4x-3+2x+4)(4x-3-2x-4) (as a²-b²= (a+b)(a-b) )
(6x+1)(2x-7) (ans)
B) (4x-3)²-(2x+4)²=0
=>(6x+1)(2x-7)=0 (as we have gotten from a that (4x-3)²-(2x+4)² is equal to (6x+1)(2x-7) )
=>6x+1=0
=>2x-7=0
=>6x=-1
Therefore
x=-1/6
=>2x-7=0
=>2x=7
Therefore
x=7/2

I need the value of X
Answer:
x=36
Step-by-step explanation:
By vertical angles we know that
[tex]72 = 2x\\\\x=\frac{72}{2}\\\\x=36[/tex]
Answer:
x = 36
Step-by-step explanation:
72 and 2x are vertical angles, so they are equal.
2x = 72
2x/2 = 72/2
x = 36

Lin found the area of a rectangle with a of length 5 in and a width of 3 inches, to be 15 square inches. Lin creates another rectangle that is a scaled copy with a scale factor of 2. What is the area of the new rectangle? How did you find it?
Answer:
60in^2Step-by-step explanation:
Step one:
given data
lenght L= 5in
width W= 3 in
area= L*W
area= 5*3= 15in^2
Step two:
The rectangle was scaled by 2, this means that the dimensions were doubled
therefore the lenght and width will be
L=5*2= 10
W=3*2= 6
hence the area is
Area= 10*6= 60in^2

Rules & Examples of Integers multiplication.
Step-by-step explanation:
A rational number is a number that can be expressed as a fraction of integers (positive or negative numbers). Every integer is a rational number.
They are multiplied based on following rules :
Positive (+) x Positive (+) = Positive (+) , +2 x +2 = 4 Positive (+) x Negative (-) = Negative (-) , +2 x -2 = -4 Negative (-) x Positive (+) = Negative (-) , -2 x +2 = -4 Negative (-) x Negative (-) = Positive (+) , -2 x -2 = 4Answer:

What is the sum of the measures of the exterior angles of this triangle
Answer:
180°
Step-by-step explanation:
because because that's how much the angle of this triangle is
The sum of the exterior angles is always 360. This applies to any polygon.

Lines and Angles
When lines cross, the angles formed in the intersections meet certain properties that help us to solve some geometry problems.
We must recall the so-called linear angles, defined as the adjacent angles formed in the point where two lines cross.
Linear angles always add up to 180°
We can see line m intersects with the horizontal (unnamed) line forming two pair of linear angles, thus:
29x - 3 + 15x + 7 = 180
Simplifying:
44x +4 = 180
Subtracting 4:
44x = 176
Dividing by 44:
x = 176/44
x = 4
Now below the horizontal line, we find other pair of linear angles, thus:
13y - 17 + 15x + 7 = 180
Substituting x=4:
13y - 17 + 60 + 7 = 180
Simplifying:
13y + 50 = 180
Subtracting 50:
13y = 180 - 50 = 130
Dividing by 13:
y = 130/13 = 10
y = 10
Answer: x=4, y=10
A recipe for shepherd's pie uses 3 cups potatoes, 2 cups carrots, 1 cup onions, 1 ½ cups ground round to create enough for 6 people. If you need to feel 16 people, how many cups of carrots do you need? Use scale factors and ratios to solve this problem. Remember to show your work.
Answer:
[tex]5\frac{1}{3}[/tex] cups of carrot.
Step-by-step explanation:
Let's set up proportional equation.
6 people need 2 cups of carrots
Let 16 people need x cups of carrots.
We could form ratio for number of people to cups of carrot used as
6:2
16:x
So, proportional equation would be
[tex]\frac{2}{6} =\frac{x}{16}[/tex]
Cross multiply
32=6 x
Divide both sides by 6.
x=[tex]\frac{32}{6}[/tex]
Divide to get mixed number
x=5[tex]\frac{2}{6}[/tex]
Simplify the fraction
x=[tex]5\frac{1}{3}[/tex] cups of carrot.
