Answer:

60 seconds

Step-by-step explanation:

step 1.) find how many meters it falls per second

          40m / 4sec = 10m/s

step 2.) use the equation above to find in terms of the question

          10m/s for 6sec = 10 x 6 ====> 60 seconds

Answer:

121is your answer

<1+<2=180(linear pair)

4x-1+9x-14=180

13x-15=180

13x=180+15

x=195/13=15

Answer:

15 I just stared so I am bad but I think I am correct

Answer:

Step-by-step explanation:

All are true except for the second.  Only the second is false.

(pi)(d) is the circumference (not the area) of a circle.

The incorrect statement is [tex]A = \pi d[/tex].

The correct option is 2.

The area is the area occupied by a two-dimensional flat surface. It has a square unit of measurement. The surface area of a three-dimensional object is the space taken up by its outer surface. Square units are used to measure it as well. The region that includes the base(s) and the curved portion is referred to as the total surface area. It is the overall area that the object's surface occupies. The total area of a form with a curved base and surface is equal to the sum of the two areas.

As per the given data:

We have to find out the incorrect statements out of the given options about the area of a circle.

[tex]A = \pi r^2[/tex]

This statement is correct, as the area of a circle is pi times square of the radius.

[tex]A = \pi d[/tex]

This statement is incorrect, as the area of a circle is given by:

[tex]A = \pi r^2 =\frac{ \pi d^2}{4}[/tex]

The area of a circle determines how much space is covered by the circle.

This statement is correct.

The area of a circle describes the number of square units that fit inside the circle.

This statement is correct.

Hence, the incorrect statement is [tex]A = \pi d[/tex].

15) True

Step-by-step explanation: hope this help :)

The absolute value of a number is the distance from 0 to that number. The distance is positive, hence, the absolute value is always a positive number.

Replace the value of x:

[tex]| x - 8 |[/tex]

[tex]| -4 - 8 |[/tex]

[tex]| -12 | = \large{\boxed{12}}[/tex]

The absolute value of a number is the numerical value of the number, without regard to its sign.

Answer:

2

Step-by-step explanation:

25 x 0.08 = 2

=========================================================

Work Shown:

Apply the law of sines

sin(N)/MO = sin(O)/MN

sin(N)/18 = sin(17)/6

sin(N) = 18*sin(17)/6

sin(N) = 0.87711511416821 ................. which is approximate

N = arcsin(0.87711511416821)

N = 61.296295678111

N = 61 degrees approximately

Answer:

0

Step-by-step explanation:

4(m+2) = -4(m-2)

by dividing over 4 :

m+2 = -1(m-2)

= m+2 = -m+2

by subtracting 2 :

m = -m

by adding "m" :

2m = 0

So

m = 0

I hope that the explanation is clear for you.

Answer:

x ≤ 13.2.

Step-by-step explanation:

6  ≥  x/2.2

Multiply both sides by 2.2:

6 * 2.2 ≥ x

x ≤ 13.2.

The solution to the inequality is [tex]x \leq 13.2[/tex], the correct symbol used in blank is  ≤.

To complete the solution to the inequality [tex]6 \geq \frac{x}{2.2}.[/tex]

Rearrange the inequality as follows:

[tex]\frac{x}{2.2} \le 6[/tex]

The solution to the inequality is:

[tex]x \leq 13.2[/tex]

Comparing the expression [tex]\frac{x}{2.2}[/tex] to 6, we can see that [tex]\frac{x}{2.2}[/tex] should be less than or equal to 6 in order for the inequality to hold true.

Therefore, the correct symbol to place in the blank is "≤" and solution is [tex]x \leq 13.2[/tex].

Answer:

C. 116º

Step-by-step explanation:

Both sides are congruent, so the triangle is an isosceles triangle. So angle Z will have to be congruent to angle X. Add together the two angles, (32 + 32) and subtract the sum from 180º since all triangles add up to 180º.

32 + 32 = 64

180 - 64 = 116

Answer:

1/6

Step-by-step explanation:

Given the function

f(x)=x^3+x^2+x

Get the inverse. Let y = f(x)

y = x^3+x^2+x

Replace y with x

x = y³+y²+y

Differentiate with respect to x

1 =3y²dy/dx + 2ydy/dx + dy/dx

1 = (3y²+2y+1)dy/dx

dy/dx = 1/3y²+2y+1

g'(x) = 1/3(g(x))²+2g(x)+1

If x = 3

g'(3) = 1/3(g(3))²+2g(3)+1

g'(3) =1/3(1)²+2(1)+1

g'(3) = 1/3+2+1

g'(3) = 1/6

Hence g'(3) = 1/6

Answer:

47

Step-by-step explanation:

54-7=47

I'm assuming we are trying to find Rita's score. We know that the total is 54. "The sum" refers to addition, so we must reverse the problem to find her score

54- 7= 47

Total - 7 = her score
