Answer:
a= 804.25
Step-by-step explanation:
a=pir^2=pi16^2=804.24772
Answer:
256 π units²
Step-by-step explanation:
The appropriate formula is A = πr².
With r = 16 units, we get:
A = (16 units)²π = 256 π units²
Note: this is the area in terms of pi, as requested.

A gallon of paint can cover 360 square feet. The radius of a standandard NBA basketball is 4.75 inches. How many basketballs will the paint cover? ( note 144 square inches in 1 square foot )
===========================================================
Explanation:
We're told that 1 square foot is 144 square inches (this is from 12*12 = 144, since 12 inches = 1 ft).
So because of this, 360 square feet converts to 360*144 = 51,840 square inches.
One gallon of paint can cover 51,840 square inches.
Now let's find the surface area of the sphere, aka ball.
It has a radius of r = 4.75 inches, so,
SA = 4*pi*r^2
SA = 4*pi*(4.75)^2
SA = 90.25pi
SA = 283.528736986479 which is approximate
The surface area of one ball is roughly 283.528736986479 square inches.
Divide the amount of area the paint can cover over the surface area of one basketball:
(51,840)/(283.528736986479) = 182.838609415709
This rounds down to 182. We round down because we won't have enough paint to cover the 183rd basketball.
One gallon of paint can cover 182 basketballs.

Equivalent fractions always have the same

Every fraction has
equivalent fractions.
Equivalent fractions are fractions that represent the same value or amount, despite having different numerators and denominators.
In other words, equivalent fractions have the same ratio or proportion, but may be written in different forms.
For example, the fractions 1/2 and 2/4 are equivalent fractions because they represent the same amount, which is half of a whole.
Also, 3/5 and 6/10 are equivalent fractions because they both represent three-fifths or 60% of a whole.

Mon august 6 ,4:56 PM ET
Washington ( Reuters): consumption of more than 3 cups coffee protect older women against some
age related memory decline. although it does not effects men's the same way.
(3) I womens those who have 3 or more cups of coffee than those of having 1 or fewer cups of coffee has lower odds of 33% of memory loss and 18 % visual and spatial decline. Also women it is seen that 80 repeaing women's are more benefits in comparison of who were 10 to 15 year younger.

Is -2/3(-12b-6+9b-18) equivalent to 2(b+8)? Show your work.
please help.
Answer:
Step-by-step explanation:
-2/3(-3b-24) = 2(b+8)
6b/3+48/3 = 2b+16
2b+16 = 2b+16 => equivalent
Is -2/3(-12b-6+9b-18) equivalent to 2(b+8)?
To find out, simplify the left side.
Multiply every term in the parentheses by 2/3.
(8b + 4 - 6b + 12)
Simplify.
(2b + 16)
Factor out 2.
2(b + 8)
We conclude that -2/3(-12b-6+9b-18)
equals 2(b + 8).

Find a Quadratic equation whose roots are 1.5+√2 and 1.5-√2
Answer:
x² - 3x + 0.25 = 0
Step-by-step explanation:
Given a root x = a then the corresponding factor is (x - a)
Given roots x = 1.5 + [tex]\sqrt{2}[/tex] and x = 1.5 - [tex]\sqrt{2}[/tex] then the factors are
(x - (1.5 + [tex]\sqrt{2}[/tex] ) ) and (x - (1.5 - [tex]\sqrt{2}[/tex] ) ) , that is
(x - 1.5 - [tex]\sqrt{2}[/tex] ) and (x - 1.5 + [tex]\sqrt{2}[/tex] )
The equation is then the product of the factors
(x - 1.5 - [tex]\sqrt{2}[/tex] )(x - 1.5 + [tex]\sqrt{2}[/tex] ) = 0 ← expand factors using FOIL
(x - 1.5)² - ([tex]\sqrt{2}[/tex] )² = 0
x² - 3x + 2.25 - 2 = 0
x² - 3x + 0.25 = 0
Swimming Pool On a certain hot summer's day, 334 people used the public swimming pool. The daily prices are $1.50 for children and $2.00 for adults. The
receipts for admission totaled $588.00. How many children and how many adults swam at the public pool that day ?
Answer: 160 children and 174 adults
Step-by-step explanation:
Let x represent the children and y represent the adults.
Create two equations:
x+y=334
1.50x+2y=588
Subtract 1.50x from the equation, then divide by 2:
y=294 - 0.75x
Plug it into the first equation then solve.
x+294-0.75x=334
x=160
Subtract 160 from 334 to get y:
y=174

H/108=7/18
Please answer proportion
Answer:
H = 42
Step-by-step explanation:
18 ÷ 108 = [tex]\frac{1}{6}[/tex]
7 ÷ [tex]\frac{1}{6}[/tex] = 42
You can check to make sure your answer is right by entering your proportions into a calculator. For example, [tex]\frac{42}{108}=0.38888888888...[/tex] and [tex]\frac{7}{18}[/tex] also equals [tex]0.38888888888...[/tex] so since they match, we know it is correct.

x⁸ + x²
Step-by-step explanation:
Here, we want to add two polynomials
To add, we check the power of both values in the expression
As we can see, the power is not the same
What this mean is that we can not add the two terms beyond this written expression
So we have the value of the polynomial expression as still being the same
SOMEONE PLEASE HELP MEE
Answer:
The missing numbers are 12 and 39 respectively
Step-by-step explanation:
From the table, we can see that the ratio of the left column to the right is 3/5
So at any point in time, the values on a particular row of the table must conform
to this ratio
In other light, we have to multiply what we have on the left by 5/3 to get what’s on the right
and we have to multiply what we have on the right by 3/5 to get what’s on the left
We have this as follows;
20 * 3/5 = 12
and;
65 * 3/5 = 39
if one zero of the following polynomial 8x^2-13x-4k is the reciprocal of the other, then find k
Answer:
k = -2
Step-by-step explanation:
2 way to solve:
1st: 8x²-13x-4k = 8(x²-(13/8)x-(k/2))
if 2 roots: a and 1/a
8(x-a)(x-1/a) = 8(x²-(13/8)x-(k/2))
x²-(a+1/a)x+1 = x²-(13/8)x-(k/2)
1 = -(k/2)
k = -2
2nd: 2 roots of 8x²-13x-4k x=(-b±√b²-4ac)/2a
x = (13±√169-4*8*(-4k))/16 = (13±√169+128k)/16
(13+(√169+128k))/16 = 16/ (13-(√169+128k)) ... root1=1/root2
(13+(√169+128k))*(13-(√169+128k)) = 16*16
13² - (√169+128k)² = 256
169-169-128k = 256
-128k = 256
k = -2

Blin and Alex raised a total of $240,000 for a charity. If Blin raised $60,000 more than Alex did, how much money did Blin raise?
Answer:
180000
Step-by-step explanation:
Solve
Given: Both Raised $240,000, Blin raised $60,000 more than Alex
To find: How much money Blin raised
Firstly, since two people raised that amount, divide the amount by 2 of them
240,000 ÷ 2 = 120,000
Nextly, subtract 60,000 from Alex's share; because Brin has more so Alex has less, less means subtract.
120,000 - 60,000 = 60,000
Now, Add that amount to Brin's share; again, Brin has more so Alex has less, less means subtract.
60000 + 120,000 = 180,000
Therefore, Brin raised $180,000
Confirm: 180,000 + 60,000 = 240,000
(For your information, Alex has $60,000)
