Isabella made $154 in interest by placing $700 in a savings account with simple interest for 2 years. What was the interest rate?
Use the formula i = prt, where i is the interest earned, p is the principal (starting amount), r is the interest rate expressed as a decimal, and t is the time in years.
Answer:
11%/ 0.11
Step-by-step explanation:
I=prt
154=700*x*2
154=1400x
divide 1400 by both sides
=0.11
or 11%
plz help me!!!!!!! its hard
For no. 1
Diameter (d) = 12 ft
Radius (r) = 12 /2 =6 ft
Area of the circle
= πr²
= 3.14 *6²
= 113.04 ft²
For no. 2
radius (r) = 12 in
Area of the circle
= πr²
= 3.14 * 12²
= 452.16 in²
Hope it helps :)❤

Which value of x is a solution to this equation?
2x^2 - 4x + 16 = 0
A. X = 3
B. X = -2
C. X = -3
D. X = 2
9514 1404 393
Answer:
no solution
Step-by-step explanation:
The discriminant is ...
b^2 -4ac = (-4)^2 -4(2)(16) = 16 -128 = -112
A negative discriminant means there are no real solutions to the equation.
_____
The complex solutions are 1±i√7.
If we assume the equation has a typographical error and is intended to be ...
2x^2 -4x -16 = 0
The solutions are x = -2 and x = 4.

Answer:
3x + y = 20 and x - 2y = - 4
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
(a)
Given
3x + y = 17 ( subtract 3x from both sides )
y = - 3x + 17 ← in slope- intercept form
with slope m = - 3
Para;;el lines have equal slopes , then
y = - 3x + c ← is the partial equation
To find c substitute (4, 8) into the partial equation
8 = - 12 + c ⇒ c = 8 + 12 = 20
y = - 3x + 20 ← in slope- intercept form
Add 3x to both sides
3x + y = 20 ← in standard form
--------------------------------------------------------
(b)
Given
y + 2x = 13 ( subtract 2x from both sides )
y = - 2x + 13 ← in slope- intercept form
with slope m = - 2
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-2}[/tex] = [tex]\frac{1}{2}[/tex] , then
y = [tex]\frac{1}{2}[/tex] x + c ← is the partial equation
To find c substitute (2, 3) into the partial equation
3 = 1 + c ⇒ c = 3 - 1 = 2
y = [tex]\frac{1}{2}[/tex] x + 2 ← in slope- intercept form
Multiply through by 2 to clear the fraction
2y = x + 4
x - 2y = - 4 ← in standard form

B. (x,y) → (x - 4, y – 10)
C. (x,y) → (x - 4, y + 10)
D. (x,y) → (x - 10, y - 4)
Answer:
B
Step-by-step explanation:
4 units to the left is subtracting
10 units down is subtracting too

The value of a stock increases by 8% each year.
1. Explain why the stock value does not increase by 80% each decade.
2. Does the value increase by more or less than 80% each decade?
Answer:
if it increases 8% each year, the next year it's not 8% of the original, but 8% of the 108% and so forth.
The increase after 10 years is (108%)^10 - 100% which is bigger than 80%.
If the value of a stock increases by 8% each year, then, that is not equal to the value of a stock increases 80% each decade.
What is Percentage Increase?The degree to which a value increases expressed in percent form is known as percentage increase.
Given that, The value of a stock increases by 8% each year.
a) If it increases 8% each year, the next year it's not 8% of the original, but 8% of the 108% and so forth, the incasement in percentage is an exponential increase not a linear increase, so we can't say that, the value of the stock increases 80% each decade
b) Since, (108%)¹⁰ > 80%
Hence, the increase after 10 years is (108%)¹⁰, will be bigger than 80%.
Hence, If the value of a stock increases by 8% each year then, that is not equal to the value of a stock increases 80% each decade

The value of w varies jointly with x and y, and w = 5 when x = 3/4 and y =2. What is the value of w when x = 4 and y = 3?
Answer:
A ∝ BCD or A = kBCD (k = constant ), then A varies jointly as B, C and D.
Step-by-step explanation:
The value of 'w' when x = 4 and y = 3 is, 40.
What are ratio and proportion?In its most basic form, a ratio is a comparison between two comparable quantities.
There are two types of proportions One is the direct proportion, whereby increasing one number by a constant k also increases the other quantity by the same constant k, and vice versa.
If one quantity is increased by a constant k, the other will decrease by the same constant k in the case of inverse proportion, and vice versa.
Given, The value of w varies jointly with x and y.
Let, w ∝ xy ⇒ w = kxy.
5 = k×(3/4)×2.
5 = (3/2)k.
k = 10/3.
Now, x = 4 and y = 3.
Therefore,
w = (10/3)×4×3.
w = 40.

Answer:
1005.3 ft³
Step-by-step explanation:
cylinder has a base diameter of 8ft and a height of 20ft. What is it's volume in cubic ft, to the nearest 10th place?
Given that:
Base diameter = 8feets
Radius, r = 8/2 = 4 feets
Height h, = 20 feets
Volume of cylinder, V = πr²h
V = π * 4² * 20
V = π * 16 * 20
V = 1005.3096
V = 1005.3096 ft³
