Answer:

Option A is correct.

Step-by-step explanation:

No of white cars: 25

No of blue cars : 17

Total number of white and blue cars = 25 + 17 = 42

No of silvers cars: 21

No of red cars: 9

Total number of silver and red cars = 21+9 = 30

No of white and blue cars more than silver and red cars

=Total number of white and blue cars - Total number of silver and red cars

=42 - 30

= 12 cars

So, Option A is correct.

The scale is evenly balanced. Explain how to find the weight (w) of one turtle.

Tomtit [17]

Answer: 8 units

Step-by-step explanation:

Set this up as an equation with a variable for turtles. Count up the other side of the scale (without turtles). Add up the three 1s and the 4 to get 7. Then add up all four 7s. This will get you with an equation 3t+4=28.

To solve this, first subtract 4 from both sides to get 3t=24. Now divide both sides by 3. 24/3=8. Each turtle weighs 8 units.

Each container has a base of 4 1/4 yds by 1 2/3 yds. What is the area covered by all the containers?

svet-max [94.6K]

Answer:

See Explanation

Step-by-step explanation:

Given

Base Dimension

$Length = 4\frac{1}{4}yd$

$Width = 1\frac{2}{3}yd$

Required

The base area of all containers

First, calculate the base area of 1 container.

This is calculated as:

$Area = Length * Width$

$Area = 4\frac{1}{4}yd * 1\frac{2}{3}yd$

Express as improper fraction

$Area = \frac{17}{4}yd * \frac{5}{3}yd$

So, we have:

$Area = \frac{17*5}{4*3}yd^2$

$Area = \frac{85}{12}yd^2$

The number of containers is not given. So, I will use 'n' as the number of containers.

So, we have:

$Total = n * Area$

$Total= n * \frac{85}{12}yd^2$

--------------------------------------------------------------------------------------------

Assume n is 3 (i.e. 3 containers)

The total area is:

$Total= 3 * \frac{85}{12}yd^2$

$Total= \frac{85}{4}yd^2$

$Total= 21\frac{1}{4}yd^2$

--------------------------------------------------------------------------------------------

Use the formula for continuous compounding to compute the balance in the account after 1,5, and 20 years. Also, find the APY for

densk [106]

Answer:

After 1 year: $7,256.59

After 5 years: $8,380.52

After 20 years: $14,381.03

APY = 3.66%

Step-by-step explanation:

If you deposit $7000 with an interest of 3.6%, after 1 year using continuous compounding, you will have

$7000e^{0.036}=7,256.59$

After 5 years you will have

$7000e^{5(0.036)}=8,380.52$

After 20 years

$7000e^{20(0.036)}=14,381.03$

To find the APY for the account, we have to compute the interest earned in one year.

We can do it by cross multiplying or by finding a number x such that

$7000(1+\frac{x}{100})=7,256.59$

Operating on this equation we obtain

x = 0.0366 or 3.66%
