Gershon lives 3 10 mile from the soccer fields. How far does Gershon walk if he walks from home to the soccer fields and back home? How many miles did he walk
Answers
Answer:
Gershon walked 620 mile
Step-by-step explanation:
From the question,
Gershon lives 310 mile from the soccer fields,
This means the distance from where Gershon lives to the soccer fields is 310 mile.
Likewise, the distance from the soccer fields to where Gershon lives his as well 310 mile.
So, if Gershon walks from his home to the soccer fields, he will cover a distance of 310 mile.
Then, if Gershon walks back home from the soccer fields, he will cover another distance of 310 mile.
Now, To determine how many miles he walked,
Total number of miles Gershon walked = The distance from where Gershon lives to the soccer fields + The distance from the soccer fields to where Gershon lives
Hence, Total number of miles Gershon walked = 310 mile + 310 mile
Total number of miles Gershon walked = 620 mile
Hence, Gershon walked 620 mile

Explain why Figure B is not the image of Figure A after a rotation using center P
Answers
Answer:
because the are not the same measurement nor the right placement
Step-by-step explanation:
The sides of figure B appear narrower than the sides of figure A.
We need to explain why Figure B is not the image of Figure A after a rotation using centre P.
What is a rotation?A rotation is a type of transformation that takes each point in a figure and rotates it a certain number of degrees around a given point.
Now,
The reason why figure B is not the image of figure A after a rotation using centre P includes
1) The angle of rotation is measured as 180 - 45 = 135°, while the angle of rotation of the base is (90 - 26) + (90 - 71) = 83°
2) Rotation of a figure is a rigid transformation, such that the dimensions of the sides of the pre-image and the sides of the image should be equal after the rotation, however, the sides of figure B appear narrower than the sides of figure A.
Therefore, the sides of figure B appear narrower than the sides of figure A.

The product of eight and a number x
Answers
Answer:
To write this down as an algebraic expression you would simply need to multiply the two terms together.
So in this case it would be 8 multiples by x which is 8x
Step-by-step explanation:
1) Find out the variables in the Expression
2) Find the operation that is done to the variables
3) Apply the operation to those variables.
The product of 8 and an unknown number x is 8x.
What is multiplication?Multiplication gives us a resultant number that will be very big as compared to the number which is going to be multiplied if and only if the number which is going to be multiplied is more than one.
Given the product of 8 and x
Product is also called multiplication.
Multiplication is an arithmetic operator which is applied in between two numbers or variables.
For example 2 × 4, 4 × 5.
So,
Product of 8 and x must be
8 × x = 8x
Hence "The product of 8 and an unknown number x is 8x".
