Answer:
Exact: 3,999,500,000
Estimate: 4,000,000,000
Step-by-step explanation:
(4)(10) = 40
(4 x 10)9 = 4,000,000,000
Notice that there are 9 zeros
_________________________________________
(5)(10) = 50
(5 x 10)5 = 500,000
Notice that there are 5 zeros
_________________________________________
4,000,000,000 - 50,000 = 3,999,500,000

write the equation in standard form for the circle with center (-5,8) and radius 4
Answer:
(x+5)^2+(y-8)^2=4^2
Step-by-step explanation:
I used a website called desmos.
Answer:
(x + 5)² + (y - 8)² = 16
Step-by-step explanation:
the equation of a circle in standard form is
(x - h )² + (y - k )² = r²
where (h, k ) are the coordinates of the centre and r is the radius
here (h, k ) = (- 5, 8 ) and r = 4 , then
(x - (- 5) )² + (y - 8)² = 4² , that is
(x + 5)² + (y - 8)² = 16
, find f^{-1}(x)f

(x)
Answer:
Multiply the numerator by the reciprocal of the denominator. Multiply x x by 1 1 . Since g(f(x))=x g ( f ( x ) ) = x , f−1(x)=1x f - 1 ( x ) = 1 x is the inverse of f(x)=1x f ( x ) = 1 x .

Is a triangle with side lengths of 14 feet, 11 feet and 8 feet a right triangle why or why not
Answer:
No , because The Pythagorean equation isn't true.
Step-by-step explanation:
a² = b² + c²
14² = 11² + 8²
196 = 121 + 64
196 ≠ 185

what is 8 6/8 ÷ 2 2/5 = ? (show ur work)
Answer:
175/48
Step-by-step explanation:
Convert 8 6/8 and 2 2/5 to fractions
8 6/8 = 70/8 ; 2 2/5 = 12/5
Now, we have : 70/8 : 12/5
= 70/8 x 5/12
= 70x5/8x12
=350/96
Simplify the fraction, we get 175/48
Your class conducts an egg-dropping experiment with 60 eggs. Three-fifths of the eggs break open, one-sixth of the eggs crack, and the rest do not break at all. How many of the eggs do not crack or break open?
Answer:
14 un cracked
Step-by-step explanation:
three-fifths of 60= 36
one-sixth of 60= 10
36+10=46
60-46=14
14 un cracked eggs

Step-by-step explanation:
Divide 243.46 by 37 to solve for t
Step-by-step explanation:
37t means 37 x t. We are solving for t.
First, we need to divide 243.46 by 37.
243.46÷37=6.58
t=6.58
Now we need to check and make sure our answer is correct.
Since we are solving for t, we need to multiply 37 by 6.58 to make sure our answer is correct.
37 x 6.58= 243.46. We got 243.46 which means it is correct.

divide £70 in the ratio 4:3
Answer:
£40:£30
Step-by-step explanation:
As we can see the ratio adds up to 7 since:
4+3=7
So now we know 1 share of the ratio will be:
£70÷7=£10
So 4 shares is £40 and 3 shares is £30

In Mrs. Nathan's class, there are 8 boys and 10 girls. What is the ratio of girls to boys in Mrs. Nathan's class? A. 5:4 B. 1:8 C. 8:1
Answer:
A. 5:4
Step-by-step explanation:
There are 10 girls and 8 boys, so the ratio of girls to boys would be 10:8. BUT we are going to simplify it. 10 and 8 both can be divided by 2, so we get a ratio of 5:4.
Answer:
[A] 5:4
Step-by-step explanation:
There are 8 boys and 10 girls.
What is the ratio of girls to boys in Mrs. Nathan's class?
10:8 is the ratio
As you can see that not a answer choice.
That cause you have to simplify.
Find the GCF. [2]
Hence, 10:8 both divide by 2
= 5:4
Thus, Answer = [A] 5:4

A circle has an area of 36π square meters.
What is the circumference of this circle?
6π meters
12π meters
18π meters
36π meters
Answer:
12π meters
Step-by-step explanation:
Area of circle = Pi*r^2 -> 36*Pi = Pi*r^2
So, radius of circle (r) = 6 m
Circumference of circle = 2*Pi*r = 2*Pi*6 = 12Pi m
For each value of , determine whether it is a solution to 28=4w.

Given the lengths of two sides of a triangle, find the range for the length of the third side (between what two numbers should the length of the third side be). Write the inequalities for each case. 8 and 13
Answer:
5 < third side < 21
Step-by-step explanation:
Let the length of the third side be [tex]x[/tex].
We know that [tex]x[/tex] must be smaller than the sum of the lengths of the two other sides. Thus [tex]x < 21[/tex].
We also know that
[tex]x+8 > 13\\x > 5[/tex]
And
[tex]x+13 > 8\\x > -5[/tex]
So, in conclusion, [tex]5 < x < 21[/tex].
Solve the system of equations by multiplying first. Enter the solution as an ordered pair.
x + 3y = -11
4x + 7y = -24
Answer:
(1, -4)
Step-by-step explanation:
In this system, multiply the top equation by -4. this will give you
-4x - 12y = 44
4x + 7y = -24
the x values can now cancel out, and add the other values together
-5y = 20
y = -4
now, substitute y = -4 in for one of the starting equations
x + 3(-4) = -11
x - 12 = -11
x = 1

How many solutions does the system have
Answer:
There are infinate solutions.
Step-by-step explanation:
Plug (3x-8) in for y
5(3x-8)=15x-40
Simplify
15x-40=15x-40
Explanation:
If we multiply both sides of the second equation by 5, then we go from y = 3x-8 to 5y = 15x-40. This is exactly identical to the first equation of the system.
Therefore, the two equations are equivalent just in slightly different forms. The two equations graph the same line which leads to infinitely many solutions.
The solutions are of the form (x, 3x-8) where x is any real number.
Since there are infinitely many solutions, we consider this system to be dependent.
