Answer 1

Answer:

312.5 t⁴

Step-by-step explanation:

25*t⁻⁴ = (5²) / t⁴     (1)

5⁻³*10*t⁻⁸ = 5⁻³*2*5¹ / t⁸   (2)

(1)/(2): ((5²) / t⁴) / ((5⁻²*2) / t⁸) = 5⁴ * t⁴ / 2 = 625 t⁴ / 2 = 312.5 t⁴

Answer 2

Answer:

If ABCD is a square what is m< AEB
A) 30°
B) 45°
C) 60°
D) 90°

Answers

Answer:

90

Step-by-step explanation:

The angle of AEB is 90 degrees, took the test and got it correct!

The measure of m<AEB is 90 degrees

Squares and triangle

From the given square, the triangle AEB is a right triangle.

A right triangle has one of its angles to be 90 degrees.

According to triangles AEB, m<EAB = m<ABE = 45 degrees

m<AEB = 180 - (45+45)

m<AEB = 180 - 90

m<AEB = 90 degrees

Hence the measure of m<AEB is 90 degrees

The sketch of this crayon represents an irregular polygon. Find the area of the figure. 21.75 cm²
75 cm²
37.5 cm²
40.5 cm²​

Answers

The total area of the sketch will be 40.5 cm².

What is Area?

The area is the entire amount of space occupied by a flat (2-D) surface or an object's form. On a sheet of paper, draw a square using a pencil. It has two dimensions. The area of a form on paper is the area that it occupies.

Given, The sketch of this crayon represents an irregular polygon.

Dimension of the polygon are given in the figure,

To calculate the area of the given figure first we need to break this into two parts:

The first one will be rectangular form with a length of 12.5 cm and a width of 3 cm

The second one will be in triangular form with a height of 2 cm and a base of 3 cm.

Area of rectangle = length * width

in our case,

Area of rectangle = 12.5*3

Area of rectangle = 37.5 square cm

Area of triangle = 1/2 base *height

In our case,

Area of triangle = 1/2* 3 * 2

Area of triangle = 3 square cm

So,

The total area of the sketch = area of rectangle +area of the triangle

The total area of the sketch = 37.5 + 3

The total area of the sketch = 40.5 Square cm

Therefore, the total area of the sketch will be 40.5 cm².

solve for x

7(8-x) = 210

Answers

Answer:

x=266

Step-by-step explanation:

I'm sure if this is correct but this is how I did it seven times eight is 56 and you have to subtract that number by x so x would have to be bigger so it would be 56 minus 266

will give you 210

Answer:

x=-22

Step-by-step explanation:

7(8-x)=210

you would use the distributive property

56-7x=210

then subtract both sides by 56

-7x=154

then divide both sides by -7

x=-22

Answer:

  74

Step-by-step explanation:

The recursive definition is for an arithmetic sequence with a first term of -6 and a common difference of 4.

The general term of such a sequence is ...

  a(n) = a(1) +d(n -1)

This sequence is ...

  a(n) = -6 +4(n -1) = 4n -10

Then for n = 21, the term is ...

  a(21) = 4(21) -10 = 84 -10

  a(21) = 74

Gawain bilang 2: tukuyin ang mga bahagi ng sanaysay mula sa akdang binasa.(Komunikasyon P. 263-264) 1. What happened in Boston according to this article? Read the following article.The Automobile and Its ImpactFor most Americans, not a day goes by that they are not affected by cars. The automobile has had more of an impact on American life than any other mode of transportation. The automobile has changed where people live, how people work, and how people view one another.In the early 20th century, people who worked in cities had to live in those cities. People lived in crowded apartments with very little room for their families. When the automobile became available to the masses, people were able to move outside of cities to live. The automobile is what led to the growth and development of the suburbs. People began building homes on the outskirts of cities. Soon these places became communities with roads, police stations, and restaurants. This helped create jobs in those areas. People could choose whether they wanted to drive their car to work in the city or closer to home. Either way, this choice and way of life would not be possible without the automobile.Cities were not the only areas affected by cars. The invention of the automobile helped increase farm production and distribution. Before the invention of the car, farmers used horses to travel. They were limited to only traveling 1520 miles. Now, with cars and later trucks, farmers could deliver their products many miles away. This meant that more people could buy their products, and the farmer could earn more money. This also meant that people could enjoy produce that was not locally grown. Cars did not only have positive impacts on American society. The invention of the car created a new class system for Americans. In the early 20th century, only the wealthy were able to own cars. Over time, cars became status symbols. Some cars were created simply as a symbol of wealth and class. That is still the case today. Cars have also created more pollution. The gasoline that cars need to run has negatively affected the air. The more cars there are, the more polluted the air becomes.The invention of the car has changed how people live in both positive and negative ways. This cannot be said for any other mode of transportation. Although ships and planes have made travel more convenient, they have not impacted a person's everyday life in the same way as cars.What evidence does the author use to support the idea that cars increased farm distribution? Farmers could now farm different types of produce. Farmers could now live in cities and work in farms. Farmers could now travel more than 1520 miles a day. People who lived in suburbs could now start a farm.
