Jose unlocks his cellphone by placing his right thumb on a square of 1 centimeter by 1 centimeter at the center of the screen. Upon recognizing his thumbprint, the square expands outward. The cellphone unlocks when the perimeter reaches 32 centimeters, taking a total of 2.5 seconds. What is the perimeter of the square after 1.5 seconds? How is the answer 20.8?

Answer:

2000 ; 2000

Step-by-step explanation:

Given the following :

Total amount borrowed = 4000

Total interést paid = 424

Simple interést = (principal * rate * time)

Rate 1 = 9.2% = 0.092

Rate 2 = 12% = 0.12

Let amount borrowed at 9.2% = x

Amount borrowed at 12% = y

x + y = 4000 - - - - (1)

x * 0.092 + y * 0.12 = 424

0.092x + 0.12y = 424 - - - - (2)

from (1):

x = 4000 - y

0.092(4000 - y) + 0.12y = 424

368 - 0.092y + 0.12y = 424

368 + 0.028y = 424

0.028y = 424 - 368

0.028y = 56

y = 56/0.028

y = 2000

x + y = 4000

x = 4000 - 2000

x = 2000

Answer:

Descends

Step-by-step explanation:

The word descend is what indicates that a negative integer should be used.

When we talk about height we should be regarding it in increments which makes its integers positive, that is something that increases. But the question says descends, descends means a reduction in height. which is a way of describing height in an opposite or negative direction.

Step-by-step explanation:

I got it right on edge2021

The order of differences ordered from least to greatest

Pang, Ruben, Adela, Tony.

The arranging of numbers from least to largest is known as ascending order. For instance, the digits 3, 15, 28, and 49 are listed in ascending order.

Given:

             Age Difference

Adela: 0.75 year

Tony:  1 1/10 years = 11/10= 1.1 year

Pang: –0.8 year

Ruben: -1 / 2 year = -0.5 year.

So, the differences ordered from least to greatest

-0.8 < -0.5 < 0.75 < 1.1

Hence, Pang, Ruben, Adela, Tony.

Answer:

A scale is a way to resize drawings or figures to make them fit into a particular size.

Step-by-step explanation:

In 2D drawing or diagrams, a  scale factor greater than 1 enlarges the object, while a scale factor between 0 and 1 shrinks the objects, also using a scale factor of 1 changes nothing or leaves the drawing the way it is.

Furthermore, scales are represented in ratio form 1:2, telling us that say 1cm in the virtual environment or paper represents 2km in reality

Given :

A boat is being pulled into a dock with a rope attached to the boat at water level. When the boat is 12 feet from the dock, the length of the rope form the boat to the dock is 3 feet longer than twice the height of the dock above the water.

To Find :

The height of the dock.

Solution :

This will make a right angle triangle as given in link below .

Now , applying Pythagoras theorem :

[tex](2h+3)^2=h^2+12^2\\\\4h^2+9h+9=h^2+144\\\\h^2+4h-45=0\\\\(h-5)(h+9)=0[/tex]

Now , h = 5 or h = -9 .

Now , height cannot be negative .

So , height of the dock is 5 ft .

Hence , this is the required solution .

Answer:

For City A, the expression for temperature change is 9 + (-8)

The amount the temperature changes for City A = 1°F

For City B, the expression for temperature change is -1 + (-3) = -4°F

The amount the temperature changes for City B = -4°F

Step-by-step explanation:

The given information are;

In City A, the temperature rise from 8 am to  9 am = 9°F

In City A, the temperature drop from 9 am to  10 am = 8°F

In City B, the temperature drop from 8 am to  9 am = 1°F

In City B, the temperature drop from 9 am to  10 am = 3°F

The expression for that represents the temperature change from 8 am to 10 am is therefore;

For City A

Temperature change from 8 am to 10 am are

8 am to  9 am = +9°F

9 am to  10 am = -8°F

Sum, change from 8 am to 10 am = 9 + (-8) = 1°F

For City B

Temperature change from 8 am to 10 am are

8 am to  9 am = -1°F

9 am to  10 am = -3°F

Sum, change from 8 am to 10 am = -1 + (-3) = -4°F

Answer:

I think Factoring is going to be the most challenging part of Alg.1 because it seems like there are a lot of steps before finding the answers.

Explanation:

When I took algebra I, the most difficult part for me was inequalities.

I had been used to linear equations and even quadratic equations, where the operative rule is "keep the equal sign sacred" (whatever you do to one side must also be done to the other side). Once I figured out that multiplying or dividing inequalities by a negative number reverses the comparison, I was good to go.

__

These days, algebra I also includes a good dose of statistics. That seems to trip up a number of people, including me. The main thing, I think, is to stay clear on the definitions, and whether you're talking about a population or a sample. A lot of the math is easily handled by a graphing calculator or spreadsheet, so familiarity with the use of those is a great bonus (almost required).

__

You will be better equipped to go into algebra I if you have memorized multiplication tables, rules of divisibility, some mental math procedures, and squares and cubes of small integers (square ≤ 20^2, cubes ≤ 10^3). This will help immensely when it comes to factoring. Similarly, you need to be familiar with arithmetic involving decimals, fractions, and mixed numbers. Numbers in one form should offer you no more challenge than numbers in any other form.

__

A big challenge for many people is the fact that math builds on previous learning. If you don't learn the early stuff well, and practice it a lot, then you will find you have difficulty drawing on that knowledge to make the later stuff easier. It's NOT a "test and forget" sort of deal. It's a "remember this forever" sort of deal.
