Answer:

Bill does.

Step-by-step explanation:

10 is a whole number while 2 3/5 is a mixed number and 10 is greater than 2 3/5 so Bill covered the farther distance

The problem gives a distance with a fraction (not a decimal); there is absolutely no reason to convert it to a decimal.

In 4 days, Val walks

4*(2 3/5) miles

4*(13/5) miles 52/5 miles

10 2/5 miles

Compare that to Bill, who runs 10 miles every 4 days.

Answer:

What is typed in the attached Excel file is =FV(B4,B5,-B3,0,0).

Step-by-step explanation:

Note: See the attached excel file for the calculation of future value of an ordinary annuity.

Since we want to find the balance after 30 years, the function in the Excel is the FV function which is used to calculate the future value (FV) of an ordinary annuity as follows:

=FV(rate,nper,-pmt,0,0) …………………… (1)

rate = Monthly interest rate = APR / 12 = 8.99% / 12 = 0.0899 / 12 = 0.00749166666666667. Note: This is typed in cell B4 in attached excel file.

nper = periods = number of months = 30 years * 12 months = 360. Note: This is typed in cell B5 in attached excel file.

pmt = monthly payment = $300. Note: This is typed in cell B3 in the attached excel file. And also typed as a negative value in cell B7, i.e. as -B3.

pv = present value = 0. Note: This is the first 0 typed in cell B7 in the attached excel file.

type 0 = 0 this is typed to indicate that deposit is made at end of period as a regular or ordinary annuity. This is the second 0 typed in cell B7 in the attached excel file.

Based on the above, the FV function in equation (1) above is converted to the following which is typed in the attached Excel file to find the balance after 30 years:

=FV(B4,B5,-B3,0,0)

The above then gives a future value of $548,080.11 which is the balance after 30 years.

2. The width of a rectangle is 5 units less than the length. If the area is 150 square units, then find the dimensions of the re

xz_007 [3.2K]

Answer:

The length = x = 15 units

The width = x-5 = 10 units

Step-by-step explanation:

Let 'x' be the length of a rectangle

As the width of a rectangle is 5 units less than the length.

width of rectangle will be = w = x - 5 units

Area = 150 square units

Using the formula

Area = length × width

$150=\left(x\right)\left(x-5\right)$

$150=x^2-5x$

$x^2-5x=150$

Subtract 50 from both sides

$x^2-5x-150=150-150$

$x^2-5x-150=0$

$\left(x+10\right)\left(x-15\right)=0$

$ab=0\:\mathrm{then}\:a=0\:\mathrm{or}\:b=0\:\left(\mathrm{or\:both}\:a=0\:\mathrm{and}\:b=0\right)$

$x+10=0\quad \mathrm{or}\quad \:x-15=0$

$x=-10,\:x=15$

As length can not be negative. so

x = 15 units

Hence,

The length = x = 15 units

The width = x-5 = 15-5 = 10 units

I need help pleasssss

Answer:

3) 16.2

Step-by-step explanation:

The supplement to the 115° angle on the right is 65°, the same as the angle at upper left. The vertical angles at C are the same measure, so this tells you that the two triangles FCB and ACD are similar by the AA similarity postulate. That being the case, corresponding sides are proportional:

CB/CD = CF/CA

CB = CD·CF/CA = 7.2·21.6/9.6

CB = 16.2

_____

When given two "point-to-point" triangles like this, quite often there is some sort of similarity relationship involved. First, you need to figure out what it is; then you need to make use of it as needed to answer the question being asked.
