Determine If Line AB Is Tangent To The Circle. Typeyour Answer Below And EXPLAIN HOW YOU KNOW.This Should

Answers

Answer 1

Answer:

If AB is a tangent to the circle, the triangle ABO is right angled, as the angle where a tangent meets the circumference is always 90 degrees.

We also know that Pythogoras' theorem only holds for right angled triangles.

The hypotenuse is 12 + 8 as 12 is the radius so is 20.

16^2+12^2 = 256 + 144 = 400 = 20^2 so AB must be tangent.

Write a real word problem that involves dividing a decimal by a whole number

Answers

There is 75% of a pizza and there are 3 siblings who want to eat it for lunch. They divide what they have of the pizza evenly among themselves. In terms of a whole pizza, what percent did each sibling get.

This question would mean dividing 75% or .75 by 3 which would mean each person got 25% or .25 of what would be a whole pizza.
So while each person would get .33 of the current sized pizza (.75) in terms of a whole pizza it would be .25

I hope this makes sense! Sorry if I over explained it.

Scientific notation of 141700000

Answers

Answer:

1.47 * 10^8

Step-by-step explanation:

Given the value 141700000, we are to express in scientific notation

The standard form is expressed as A * 10^n

A is any integer between 1 and 10

n is also any integer

141700000.= 1.47 * 10^8

Note that the decimal point was shifted back 8 times, main reason the power is 8

On a certain hot summer day, 673 people used the public swimming pool. The daily prices are 1.75 for children and 2.00 for adults.The receipts for admission totaled to $1249.50. How many children and how many adults swam at the public pool that day?

Answers

Answer:

120 children and 388 adults bought tickets for the swimming pool

Explanation:

Create two simultanous equations:

Let c stand for the number of children that bought a ticket, and a stand for the number of adults that bought a ticket, you get your first equation, being

c

+

a

=

508

then, you now create a second equation for the prices of the tickets.

(price of childrens tickets)(number of children that swam)+(price of adults tickets)(number of adults that swam) = total money collected

so:

1.75

c

+

2.25

a

=

1083.00

now we still know, that

a

=

508

−

c

so we can substitute it into the second formula

1.75

c

+

2.25

(

508

−

c

)

=

1083

now its just simple algebra

1.75

c

+

1143

−

2.25

c

=

1083

60

=

0.5

c

so:

c

=

120

now we know, that 120 children went to the swimming pool.

and we still have the formula from before:

a

=

508

−

c

so

a

=

388

Explanation:

A linear system of two equations in two variables will be a dependent system. This means both equations reduce to the same equation. The equations will be different only until they are reduced to the same form.

Here is one possible set of equations. The first is in slope-intercept form. The second is in point-slope form.

y = 3x +1y -7 = 3(x -2)

If we subtract the first equation from the second, we get ...

  (y -7) -(y) = (3(x -2)) -(3x +1)

  -7 = 3x -6 -3x -1 . . . . . eliminates y

  -7 = -7 . . . . . . . . . true for all values of x

There are an infinite number of solutions.

The blueprint for a chicken coop have a scale of 1 inch to 5 feet. If the area of the blueprint is 15 square inches, what is the area of the actual chicken coop

Answers

Answer:

75 feet²

Step-by-step explanation:

A scale drawing is the reduced image of another image

If the scale is 1 inch to 5 feet, it means that 1 inch presents 5 feet

If the area of the blueprint = 15 inches

It means the actual chicken coop would be 5 feet times larger than the blueprint

Actual area of the chicken coop = 15 inches² x 5 = 75 feet²
