Answer:

Step-by-step explanation:

hello :

-75-(-55) = (-55)-(-35) = (-35)-(-15)=-20

the ratio diff is : d=-20

the nth term is :An=A1+(n-1)d      A1 =-15

An=-15+(n-1)(-20) = 15-20n+20

An = -20n+5

26th term when : n=26       A26 = -20(26)+5 = -515

A26= -515

Answer:

-515

Step-by-step explanation:

In this example the first value is −15 and every value afterwards is 20 less.

After substituting these values to above formula, we obtain:

All we have to do is add 25 twenties or 25 x 20 = 500 and -15 - 500 = -515

Dahlia is trying to decide which bank she should use for a loan she wants to take out. In either case, the principal of the loan
vovangra [49]

Answer:

  a.  Loan Q’s finance charge will be $83.73 greater than Loan P’s.

Step-by-step explanation:

<u>Loan P</u>

Monthly payments for a 9-year 5.8% loan for $19,450 are $231.59, so the total repaid is ...

  108 payments × $231.59 per payment = $25,011.72

Together with the service charge, the cost of the loan is ...

  $25,011.72 + 925.00 - 19,450 = $6,486.72

__

<u>Loan Q</u>

Monthly payments for a 10-year 5.5% loan for $19,450 are $211.08, so the total repaid is ...

  120 payments × $211.08 per payment = $25,329.60

Together with the service charge, the cost of the loan is ...

  $25,329.60 +690.85 -19,450 = $6,570.45

__

Difference of charges

The cost of Loan Q exceeds that of Loan P by ...

  $6,570.45 -6486.72 = $83.73 . . . . . matches choice A

_____

The payment values here were computed using a financial calculator. They can be found using the TVM Solver of a graphing calculator (TI-84), or by any spreadsheet. A number of web sites will also calculate loan payment values, or you can use the formula in your text to compute them yourself.

If a 10-pound turkey costs $20.42.how much does a 21-pound turkey cost
sergij07 [2.7K]

Answer:

$42.88

Step-by-step explanation:

Let's create a proportion using the following setup:

cost/pounds=cost/pounds

We know that it costs $20.42 for a 10 pound turkey.

$20.42/10 pounds= cost/pounds

We don't know how much a 21 pound turkey costs, so we can say that it costs $x for a 21 pound turkey.

$20.42/ 10 pounds= $x/ 21 pounds

20.42/10=x/21

We want to find x, by getting x by itself.

x is being divided by 21. The inverse of division is multiplication. Multiply both sides by 21.

21*(20.42/10)=(x/21)*21

21* 20.42/10=x

21*2.042=x

42.882=x

Round to the nearest cent, or hundredth.

42.88=x

x= $42.88

A 21 pound turkey costs $42.88

The dot plot represents an order of varying shirt sizes. A number line going from 8 to 26. 0 dots are above 8. 1 dot is above 10
raketka [301]

Answer:

The histogram for the given data is shown below.

Step-by-step explanation:

In a dot plot, the dots above a point represent the frequency of that number.

From the given dot plot we can make a frequency table as shown below.

Number        Frequency

     8                     0  

    10                     1

    12                     3

    14                     3

    16                     5

    18                     4

    20                    2

    22                    1

    24                    1

    26                   0

In histogram, each bar above a number represents the frequency of that number.

The histogram for the given data is shown below.

Suppose a snow cone has a paper cone that is 8 centimeters deep and has a diameter of 5 centimeters. The flavored ice comes in a
Neko [114]

check the picture below.


so the cone itself has a height of 8, and a radius of 2.5, and the spherical scoop, ready to melt in it, has a radius of 2.5.


namely, will the volume of the sphere be larger than the cone? in which case the melted ice-cream will overflow.


\bf \textit{volume of a cone}\\\\ V=\cfrac{\pi r^2 h}{3}~~ \begin{cases} r=2.5\\ h=8 \end{cases}\implies V=\cfrac{\pi (2.5)^2(8)}{3}\implies \implies \boxed{V=\cfrac{50\pi }{3}} \\\\\\ \textit{volume of a sphere}\\\\ V=\cfrac{4\pi r^3}{3}\qquad r=2.5\implies V=\cfrac{4(\pi )(2.5)^3}{3}\implies \boxed{V=\cfrac{125\pi }{6}} \\\\\\ \textit{the sphere's volume is larger, so yes, it will overflow}
