Who knows what a black widow spider can do

The orange will fall 64 feet in 8 seconds.

Distance:

Distance is defined as how much ground an object has covered despite its starting or ending point.

Given,

The distance a falling object travels towards the earth is directly proportional to the square of the time that it falls.

And an orange falls 16 feet in 4 seconds.

Here we need to find the how far it will fall in 8 seconds.

Based on the given details,

We know the that distance is,

D = kt²  

where

k is the constant of proportionality.  

To find the value of k we have to apply the given values on the equation.

=> 16 = k x (4)²

=> 16 = k x 16

=> k = 16/16

=> k = 1.

So, in 8 seconds it will fall at

=> D = 1 x (8)²

=> D = 1 x 64

=> D = 64 feet.

Therefore, the orange will fall at 64 feet in 8 seconds.

Answer:

Full-time worker minimum monthly income = US$ 7,846.40

Part-time worker minimum monthly income = US$ 7,846.40

Full-time worker hourly wage = US$ 49.04

Part-time worker hourly wage = US$ 98.08

Step-by-step explanation:

1. Let's review the information given to answer the question correctly:

Monthly costs of a 2-adult and 3-children family in the Modesto metro area = US$ 7,846

Full-time worker = 4 weeks of 40-hour per month

Part-time worker = 2 weeks of 40-hour per month

2. Let's calculate the minimum monthly income and hourly wage per worker

Full-time worker hourly wage = Monthly costs/160

Part-time worker hourly wage = Monthly costs/80

Full-time worker hourly wage = 7,846/160

Part-time worker hourly wage = 7,846/80

Full-time worker hourly wage = US$ 49.04

Part-time worker hourly wage = US$ 98.08

Full-time worker minimum monthly income = Hourly wage * 160

Part-time worker minimum monthly income = Hourly wage * 80

Full-time worker minimum monthly income = US$ 7,846.40

Part-time worker minimum monthly income = US$ 7,846.40

Here, they used the Pre-Experimental design concept,

In the Pre-Experimental concept,

They used the static group comparison method,

Basically, the process of static group comparison method is,

In a static-group comparison study, 2 or more groups are placed under observation, where only one of the groups is subjected to some treatment while the other groups are held static. All the groups are post-tested, and the observed differences between the groups are assumed to be a result of the treatment.

The distance between the beach and Alisa's house is 99 miles.

Here we need to use the general relation:

Distance = Speed*Time.

Here we know that Alisa's speed is 55 miles per hour, and she drives for 1.8 hours, then we can replace:

Speed = 55 mi/h

Time = 1.8 hours

Replacing that in the distance relation we will get:

D = (55 mi/h)*(1.8 h)= 99 mi

Making Vi the subject of formula gives the following expression: Vi = √(Vf² - 2aX).

An expression can be defined as a mathematical equation which is used to show the relationship existing between two or more variables and numerical quantities.

In this exercise, you're required to describe the steps that should be taken to rearrange and make Vi the subject of formula. Therefore, the appropriate and required steps are listed as follows:

Vf² = Vi² + 2aX

Subtracting 2aX from both sides of the equation, we have:

Vf² - 2aX = Vi² + 2aX - 2aX

Vi² = Vf² - 2aX

Taking the square root of both sides, we have:

Vi² = Vf² - 2aX

Option B) is correct that is shape 2 is congruent to shape 1 because shape 2 is reflection of shape 1.

We know that two figures or objects are congruent if they have the same shape and size or they are the mirror image of each other.

Translation : It simply means moving. Every point should be moved in same distance and in same direction

Rotation : It means turning around a center.

Reflection : In this, the image is of the same size as the pre-image.

So according to the given figure we can see that the shape is not translated or rotated from a center but is reflected as shape 1 is the image of shape 2.

Step-by-step explanation:

To find how much Ben's rent is per month, we first have to find how much Ben spends on rent annually (every year). We can do this by multiplying his annual salary by the percentage spent on rent.  

22000 · 0.15 = 3300

Now that we know Ben spends 3300 on rent a year, we can divide that amount by 12 (the number of months in a year) to find out how much his rent is per month.

3300 / 12 = 275

Answer:

0.16 for one egg. 1.90 for a dozen.

Step-by-step explanation:

For 24 eggs it is 3.79 dollars, so to find the price of one egg we just divide 3.79 by 24, which is 0.16.

There are 12 eggs in a dozen, and it's 3.79 for 24 eggs, so I can divide it by 2 to get to a dozen, so 3.79/2 = 1.90

Answer:

.16 per egg

1.90 for a dozen

Step-by-step explanation:

Take the total cost and divide by the number of eggs to find the cost for one egg

3.79/24 =.157916667

Since this is money we round to the nearest cent

.16

The cost per one egg is .16 or 16 cents

Multiply this by 12 to get the cost of 12 eggs

3.79/24  * 12 =1.895

This will round to 1.90

(Do not use the rounded answer to find the cost of a dozen eggs, because it will be higher.  We need to use the exact answer when calculating)

The equation for a​ two-week trip of 500 miles' rental cost is Total rent cost = 2x + 500y

Information about the problem:

To solve this problem, we have to state the equation using the information of the problem:

Car rent for 2 weeks = 2x

Car rent for 500 miles = 500y

Total rent cost = 2x + 500y

Example:

Car rent per week = $280/ week

Car rent per miles = $0.75/ mile

Total rent cost = (2 weeks * $280/ week) + (500 miles * $0.75/ mile)

Total rent cost = $560 + $375

Total rent cost = $935
