The sides of a rectangle are in the ratio of 4:5. If the width is 28 in., find the length, the perimeter, and the area of this r

nadezda [96]

If the width is 28 inches, then divide that by 4 and you get 7. You multiply that by 5 to get the length. That would be 35. Just to check, you know that the width 28 and length 35 are in ratio 4:5 if you divide by 7. The perimeter would be 2(35+28)=63*2=126. So the perimeter is 126. The area would be 35*28 which is 980. To sum up, the answers are as follows.

Length: 35 in
Perimeter: 126 in
Area: 980 inches squared.

Jana joined a music club that offered her 5 CDs for a total of 3.00 if she agreed to purchase an additional 10 CDs for 15.00 eac

Hunter-Best [27]

Answer:

Average price, excluding taxes, for each CD is <u>10.20</u>.

Step-by-step explanation:

Given:

Cost of first 5 CDs, $C_1 = 3.00$

Cost of each additional CD = 15.00

Now, cost of 10 additional CDs is the product of cost of one CD and total number of additional CDs. Therefore,

Cost of 10 additional CDs is, $C_2=15.00\times 10=150.00$

Now, total CDs purchased by Jana are, $N=5+10=15$

Total cost of the 15 CDs purchased is given as:

$C_T=C_1+C_2=3.00+150.00=153.00$

Now, average price, excluding taxes, for each CD is given as:

$\textrm{Average price}=\frac{\textrm{Total cost of purchase}}{\textrm{Total number of CDs purchased}}\\\\\textrm{Average price}=\frac{C_T}{N}=\frac{153.00}{15}=10.20$

Therefore, the average price, excluding taxes, for each CD is 10.20.

BRAINLIESTTT ASAP!! PLEASE HELP ME :)

Andrej [43]

Answer:

2017.

Step-by-step explanation:

The equation for the future sale of motorcycles

= 5.75(1.16)^t where t is in years

For cars it is

3.5(1.25)^t

3.5(1.25)^t > 5.75(1.16)^t

(1.25)^t > (5.75/3.5) 1.16^t

t ln 1.25 > ln 1.64286 + t ln 1.16

t ln 1.25 - t ln 1.16 > ln 1.64286

t (ln 1.25 - ln 1.16) > ln 1.64286

t > ln 1.64286 / (ln1.25 - ln 1.16)

t > 6.64 .

So the answer is in the year 2017.
