Answer:

1. False

2. True

3. True

Step-by-step explanation:

Remark

The point of this question is to encourage you to make use of your calculator. Every calculator can find square roots as far as I know.

Givens

\sqrt{70} = 8.367

\sqrt{72} = 8.49

\sqrt{77} = 8.77

One

Point A is roughly 8.15. The square root of 70 is over 8.3 So square root 70 is to the right of point A. False.

Two

Square root 72 is 8.49. B is 8.3 and C is 8.6. The statement is True

Three

sqrt(77) = 8.77. Point D is 8.75.  The answer is true, but I wouldn't want to bet money on it. The difference is slightly less than 2 100s.

Help please with this math ;-; I beg of you
RSB [31]

Answer:

49 - 9π

Step-by-step explanation:

Area of white portion = area of triangle - area of circle

To find the area of the triangle:

The area of a triangle can be calculated using this formula

A=\frac{bh}{2} where b = base length and h = height

The height given is 7m and the base length given is 14m

That being said we plug in the given values into the formula

\frac{14*7}{2} \\14*7=98\\\frac{98}{2} =49

Hence, the area of the triangle is 49 sq meters.

To find the area of circle

( note that the area is in terms of pi; shown by the answer choices. )

Formula for area of a circle = A=\pi r^2

We are given the diameter  ( 6m )

However, we need the radius

To convert diameter to radius we divide by 2

6/2 = 3 so the radius = 3m

Now we plug in 3 into the formula

A=\pi 3^2\\3^2=9\\A=9\pi

Remember we do not apply pi because the answer should be in terms of pi.

Now we subtract the two

Area of white portion = 49 - 9π

Hence, the answer is A

The Maria Island breeding program started in 2012, when Devil Ark released 15 devils. About 13% of them have died. How many is t
Marat540 [252]
The answer is:  "about 2" .
___________________________________________

13% of 15 is _?_<span>_ ?
</span>
13% = 13/100 = 0.13 
 
15 * 0.13 = 1.95 ;   so about 2 animals (devils, in this case).

Jet001 [13]

Remark.

The problem is a bit indistinct. Where exactly are the two edges of the road? I'm going to say that they are the x intercepts, but that may not be true. Certainly it does not have to be true at all.


Graph.

A graph has been made for you. The maximum is marked for you. It is an approximation The actual height can be more accurately found.


Height

y = (-1/200)(x - 16)(x + 16)

y = (-1/200)*(x^2 - 256)


The maximum height for this graph only is when x = 0.Other graphs require completing the square.


y = (-1/200) * (-256)

y = 1.28 exactly. I thought the graph might be rounding the answer. It is not.
