Answer:

Randy walks in his daily routine:

500 meters.

Step-by-step explanation:

We are going to take the points of the Cartesian plane and take distances, in the first instance the points (-5, -2) and (-5, 9), if you locate these points on the plane you will realize that the distance that separates them is 11 units, then you locate the point (9, 9) and you will notice that it separates from the point (-5, 9) in 14 units, so you can continue locating the remaining points and measuring their distances, however, I anticipate you that since it is a perfect rectangle, there are two short sides of 11 units and two long sides of 14 units, so the perimeter of the rectangle is:

Perimeter of the rectangle = 14 * 2 + 11 * 2
Perimeter of the rectangle = 50 units.

As the problem specifies that each unit corresponds to 10 meters, the value in units must be multiplied by 10 and obtain said value in meters:

Perimeter of the rectangle in meters = 50 * 10 = 500 meters.

For this reason, Randy walks his neighborhood for a total of 500 meters.

NEED HELP ASAP

algol [13]

Answer:

A) car one is linear because it decreases the same amount every year.

car two decreases by the same ratio so it's exponential.

B) for car one y = -6,000x + 38,000 (y is the value after x years, -6,000 is what it changes by every year, and 38,000 is the amount of year 0)

for car two y = (44,000) (17/20)x-1 (y is the value after x years, 44,000 is the amount on year 0, and 17/20 is the ratio)

C) after 5 years car one will be 8,000

after 5 years car two will be about 16,860

A jeweler is dividing

tatuchka [14]

Question:

A jeweler is dividing 3/8 of a pound of rubies among 4 lots. What part of a pound will each lot weigh? A.1/4 B.1/8 C.1/16 D.3/32

Answer:

Option D

Each lot weight $\frac{3}{32}$ part of pound

Solution:

Given that,

A jeweler is dividing 3/8 of a pound of rubies among 4 lots

To find: part of a pound each lot weigh

From given,

$\frac{3}{8} \text{ of a pound } = 4 lots$

Let "x" be the part of a pound each lot weigh

Therefore,

$\frac{3}{8} \text{ of a pound } = 4 lots\\\\"x" part = 1\ lots$

This forms a proportion and solve by cross multiplying

$\frac{3}{8} \times 1 = 4 \times x\\\\x = \frac{3}{32}$

Thus, each lot weight $\frac{3}{32}$ part of pound

A student filled a right rectangular prism shaped box with one inch cubes to find the volume in cubic inches the students work i

den301095 [7]

The volume of the right rectangular prism is the amount of cubes in it

The formula to determine the volume of the right rectangular prism is V(n) = n

<h3>How to determine the volume?</h3>

The question is incomplete; as the figure is not given.

So, I will provide a general solution

The volume of a one inch cube is:

$V = 1^3$

$V = 1$

Assume the number of one inch cubes used to fill the right rectangular prism is n.

Then the volume of the right rectangular prism would be:

$V(n) = n * 1$

This gives

$V(n) = n$

Hence, the general formula to determine the volume of the right rectangular prism is V(n) = n

When an opinion poll selects cell phone numbers at random to dial, the cell phone exchange is first selected and then random dig

Aliun [14]

Answer:

c. 8.25

Step-by-step explanation:

The given scenario corresponds to binomial experiment because

1. There are two possible outcomes i.e. each number can be working or not working.

2. On each dialing the probability of getting working cell number is p=0.55.

3. Cell phone numbers are randomly dialed so these are independent.

4. A pollster dialed 15 cell numbers i.e. n=15.

The mean number of calls that reach a working cell number can be calculated by computing mean of binomial distribution using the given information.

Mean of binomial distribution=E(x)=np

The mean number of calls that reach a working cell number=15*0.55=8.25

Thus, the mean number of calls that reach a working cell number=8.25
