Algebraically manipulating the formula FV = P +Prt, find the time period in years (to the nearest whole year) it would take to q
ICE Princess25 [194]

Answer:

55years

Explanation:

According to the given expression

FV = P +Prt

P is the initial deposit = $1000

FV is the future value = 4(1000) = $4000

r is the rate = 5.5% = 0.055

Required

Time t

Substitute the given values into the expression as shown;

FV = P +Prt

4000 = 1000 + 1000(0.055)t

4000 - 1000 = 55t

3000 = 55t

Swap

55t = 3000

t = 3000/55

t = 54.5years

t = 55years

This means it will take the deposit of $1000 55years to quadruple

The area of a rectangle is 63m^2 and the length of the rectangle is 11m more than twice the width. Find the length and width.
AleksandrR [38]

Answer:

width = 3.5 m

length = 18 m

Step-by-step explanation:

area = length x width

x is the width then length = 2x + 11

x(2x + 11) = 63

2x^2 + 11x - 63 = 0

The formula to solve a quadratic equation of the form ax^2 + bx + c = 0 is equal to x = [-b +/-√(b^2 - 4ac)]/2a

with a = 2

       b = 11

       c = -63

substitute in the formula

x = [-11 +/- √(11^2 - 4(2)(-63))]2(2)

x = [-11 +/- √(121 + 504)]/4

x = [-11 +/- √625]/4

x = (-11 +/- 25)/4

x1 = (-11 + 25)/4 = 14/4 = 3.5

x2 = (-11 - 25)/4 = -36/4 = -9

since width can't be a negative number, x is 3.5

length = 2x + 11 = 2(3.5) + 11 = 18

State if the two triangles are congruent. If they are, state how you know.
Gwar [14]

Answer:

The triangles can be congruent.

Step-by-step explanation:

They are congruent if proven by SSS: 2 sides are clearly stated that they are congruent due to the marks they have.

The last side can be congruent if the diagonals are congruent in length by proving.

They can also be congeuent due to SAS because there is gonna be alternate interior angles due to the transversal.
