!PLEASE HELP! A square concrete foundation was prepared as a base for a large cylindrical gasoline tank.

1 answer:

7 0

Answer: B, you have to multiply the (A) area by 10 and then you divide the circular base of the tank, then you add those 2 answers and you have it as the function of the radius!

Noah earns $16 per hour babysitting. At his last babysitting job, he received a tip of

nalin [4]

Answer:

He must work for 115 hours to save at least $1900.

Step-by-step explanation:

The equation that you'll use is 65+16x=1900, with x being hours. I found the answer by using 65+16(115)=1905, which is the closest number you'll get before starting to use half hours and such.

15/40 in lowest term I need it so bad now

Vesnalui [34]

In order to reduce ANY fraction to lowest terms, find any common factors
of the numerator and denominator, and divide them both by it. If they still
have a common factor, then divide them by it again. Eventually, they won't
have any common factor except ' 1 ', and then you'll know that the fraction is
in lowest terms.

Do 15 and 40 have any common factors ?
Let's see . . .

The factors of 15 are 1, 3, <em>5</em>, and 15 .
The factors of 40 are 1, 2, 4,<em> 5</em>, 8, 10, 20, and 40 .

Ah hah ! Do you see that ' <em>5</em> ' on both lists ? That's a common factor.

So 15/40 is NOT in lowest terms.

Divide the numerator and denominator both by 5 :

15 / 40 =<em> 3 / 8</em>

3 and 8 don't have any common factor except ' 1 '.
So 3/8 is the same number as 15/40, but in lowest terms.

Which undefined term is needed to define an angle?<br><br> Plane<br> Point<br> Ray<br> Line

Aleks04 [339]

Point.

<h3>Further explanation</h3>

The angle is determined by three points, we call it A, B, C, with A ≠ C and B ≠ C.
We express an angle with three points and a symbol ∠. The middle point represents constantly vertex. We can, besides, give angle names only with vertices. For example, based on the accompanying image, the angle can be symbolized as ∠BAC, or ∠CAB, or ∠A.

This is one of the classic problems of Euclidean geometry.

Undefined terms are the basic figure that is undefined in terms of other figures. The undefined terms (or primitive terms) in geometry are a point, line, and plane. These key terms cannot be mathematically defined using other known words.

A point represents a location and has no dimension (size). It is marked with a capital letter and a dot.
A line represents an infinite number of points extending in opposite directions that have only one dimension. It has one dimension. It is a straight path and no thickness.
A plane represents a planar surface that contains many points and lines. A plane extends infinitely in all four directions. It is two-dimensional. Three noncollinear points determine a plane, as there is exactly one plane that can go through these points.
