Answer:
≈ 7854 m²
Step-by-step explanation:
The surface area (A) of a sphere is calculated as
A = 4π r² ← r is the radius
here diameter = 50, hence r = 25, so
A= 4π × 25²
= 4π × 625 = 2500π ≈ 7854 m²
Answer:
The surface area of the structure ≅ 7854 meter²
Step-by-step explanation:
* Lets revise the surface area of the sphere
- The surface area of a sphere is the same as the lateral surface area
of a cylinder having the same radius as the sphere and a height
equal the length of the diameter of the sphere.
- The lateral surface area of the cylinder is 2πrh
- The height of the cylinder = 2r , then the surface area of the sphere is
2πr(2r) = 4πr²
* Now lets solve the problem
∵ The sphere has diameter = 50 meters
∵ The diameter is twice the radius
∴ 2r = 50 meters ⇒ divide both sides by 2
∴ r = 25 meters
∵ The surface area of the sphere = 4πr²
∴ The surface area of the sphere = 4π(25)² = 7853.98
∴ The surface area of the sphere ≅ 7854 meters²
Winslow plans to grow 12 kinds of vegetables in her garden. She has 34 seeds of each kind of vegetables. A neighbor gives her 10 more packets of seeds. Each packet has 25 seeds. How many seeds does Winslow have in all????
Answer: 658
Step-by-step explanation:
If Winslow wants to plant 12 vegetables and has 34 seeds of each kind of vegetable, then she has 12*34 seeds.
12*34=408
If a neighbor giver her 10 more packets, each with 25 seeds, she has 10*25 more seeds.
10*25=250
Then we add 408+250 to get 658 seeds

Tony has $727.29 in his checking account. He must maintain a $500 balance to avoid a fee. He wrote a check for $248.50 today. Write and solve an inequality to solve for the least amount of money he needs to deposit to avoid a fee.
727.29 + 248.50 − x ≥ 500; x ≥ $475.79
727.29 + 248.50 − x ≤ 500; x ≤ $475.79
727.29 − 248.50 + x ≥ 500; x ≥ $21.21
727.29 – 248.50 − x ≤ 500; x ≤ $21.21
Answer:
727.29 − 248.50 + x ≥ 500; x ≥ $21.21
Step-by-step explanation:
Write down all the data given :
Beginning amount : $727.29
Balance to be maintained : $ 500
Check : $248.5
Current balance = 727.29 - 248.5 = $478.79
Tony must maintain a balance of $500 so he should have at least $21.21 more (500-478.79)
727.29 - 248.5 + 21.21 = 500
500=500
x can be 21.21 or greater than that which would maintain the balance of $500 or more.
Therefore the third statement is correct.
727.29 − 248.50 + x ≥ 500; x ≥ $21.21

The sundae bar at Sarah's favorite restaurant has 5 toppings. In how many ways can Sarah top her sundae if she is restricted to at most 2 toppings?
There are 16 different ways Sarah can top her sundae, considering no toppings, 1 topping or 2 toppings out of 5 available at the restaurant.
Explanation:The subject of this question is in the field of combinatorics, a branch of mathematics. We are asked to find the number of ways Sarah can top her sundae with at most 2 toppings out of 5 available. The answer will be the number of ways she can pick no topping, or 1 topping, or 2 toppings.
The number of ways to pick no toppings is 1 (just the ice cream), to pick 1 topping out of 5 is 5 (assuming all toppings are different), and to pick 2 toppings out of 5 is represented by a combination formula '5 choose 2', which means: 5! / ((5 - 2)! * 2!) = 10, where '!' denotes factorial.
So by summing these possibilities (1+5+10), we come to the conclusion that Sarah can top her sundae in 16 different ways if she is restricted to at most 2 toppings.

Sarah can top her sundae in 6 different ways if she is restricted to at most 2 toppings.
Explanation:To calculate the number of ways or combinations, Sarah can top her sundae with at most 2 toppings, we can consider two cases. In the first case, she chooses 0 toppings. In the second case, she chooses 1 topping.
The total number of ways would be the sum of these two cases.
In the first case, she has only one choice, which is not to choose any topping.
In the second case, she can choose any one of the 5 toppings. So, the total number of ways would be 1 + 5 = 6.
Therefore, Sarah can top her sundae in 6 different ways if she is restricted to at most 2 toppings.

Answer:
f (gx) = 1/ -2(1/x^2+6x+10) + 9
Step-by-step explanation:
f (gx) = 1/ -2(1/x^2+6x+10) + 9
Answer:
The domain is all real numbers where
[tex](f \circ g)(x)=\frac{x^2+6x+10}{9x^2+54x+88}[/tex]
Step-by-step explanation:
[tex](f \circ g)(x)=f(g(x))[/tex]
So g(x) must exist before plugging it into f(x).
Let's find where g(x) doesn't exist.
[tex]x^2+6x+10[/tex] is a quadratic expression.
[tex]b^2-4ac[/tex] is the discriminant and will tell us if [tex]x^2+6x+10=0[/tex] will have any solutions. I'm trying to solve this equation because I want to figure out what to exclude from the domain. Depending on what [tex]b^2-4ac[/tex] we may not have to go full quadratic formula on this problem.
[tex]b^2-4ac=(6)^2-4(1)(10)=36-40=-4[/tex].
Since the discriminant is negative, then there are no real numbers that will make the denominator 0 here. So we have no real domain restrictions on g.
Let's go ahead and plug g into f.
[tex]f(g(x))[/tex]
[tex]f(\frac{1}{x^2+6x+10})[/tex]
I replaced g(x) with (1/(x^2+6x+10)).
[tex]\frac{1}{-2(\frac{1}{x^2+6x+10})+9}[/tex]
I replaced old input,x, in f with new input (1/(x^2+6x+10)).
Let's do some simplification now.
We do not like the mini-fraction inside the bigger fraction so we are going to multiply by any denominators contained within the mini-fractions.
I'm multiplying top and bottom by (x^2+6x+10).
[tex]\frac{1}{-2(\frac{1}{x^2+6x+10})+9} \cdot \frac{(x^2+6x+10)}{(x^2+6x+10)}[/tex]
Using distributive property:
[tex]\frac{1(x^2+6x+10)}{-2(\frac{1}{x^2+6x+10})\cdot(x^2+6x+10)+9(x^2+6x+10)}[/tex]
We are going to distribute a little more:
[tex]\frac{x^2+6x+10}{-2+9x^2+54x+90}[/tex]
Combine like terms on the bottom there (-2 and 90):
[tex]\frac{x^2+6x+10}{9x^2+54x+88}[/tex]
Now we can see if we have any domain restrictions here:
[tex]b^2-4ac=(54)^2-4(9)(88)=-252[/tex]
So again the bottom will never be zero because [tex]9x^2+54x+88=0[/tex] doesn't have any real solutions. We know this because the discriminant is negative.
The domain is all real numbers where
[tex](f \circ g)(x)=\frac{x^2+6x+10}{9x^2+54x+88}[/tex]
Five liters of water were poured from tank A into tank B. and ten liters of water were then poured into tank C. If tank A originally had 10 more liters of water than tank C, how many more liters of water does tank C now have than tank A?
Answer:
It would be 5 liters because you gave 5 liter to C
Step-by-step explanation:
Hope this helped! :3
Tank C now has 5 more liters of water than tank A.
Assume the initial amount of water in tank C is "x" liters.
Given that:
Tank A originally had 10 more liters of water than tank C,
The initial amount of water in tank A is "x + 10" liters.
When five liters of water were poured from tank A into tank B,
The amount of water in tank A is reduced to "(x + 10) - 5" liters,
The amount of water in tank A = "(x + 5)" liters.
When ten liters of water are poured into tank C
So, the amount of water in tank C= "x + 10" liters.
The amount of extra water in tank C is calculated as;
Difference = (Amount of water in tank C) - (Amount of water in tank A)
Difference = (x + 10) - (x + 5)
Difference = x + 10 - x - 5
Difference = 10 - 5
Difference = 5
Tank C now has 5 more liters of water than tank A by 5 liters.

Answer:
y=(3/2)x+-14
First blank: 3
Second blank:2
Last blank:-14
Step-by-step explanation:
The line form being requested is slope-intercept form, y=mx+b where m is slope and b is y-intercept.
Also perpendicular lines have opposite reciprocal slopes so the slope of the line we are looking for is the opposite reciprocal of -2/3 which is 3/2.
So the equation so far is
y=(3/2)x+b.
We know this line goes through (x,y)=(4,-8).
So we can use this point along with our equation to find b.
-8=(3/2)4+b
-8=6+b
-14=b
The line is y=(3/2)x-14.

The point A(-6,-5) is translated using T: (x,y) - (x + 4, y + 6).
What is the distance from A to A'?
The distance from point A to A' after translation is 2 sqrt(13).
Explanation:The given points are A(-6,-5) and A' is obtained by translating A using the transformation T: (x,y) -> (x + 4, y + 6).
So the coordinates of A' are (-6 + 4, -5 + 6) which is (-2,1).
To find the distance from A to A', we can use the distance formula.
Distance = sqrt((x2 - x1)^2 + (y2 - y1)^2)
Substituting the coordinates of A and A' into the formula, we get Distance = sqrt((-2 - (-6))^2 + (1 - (-5))^2).
Calculating the distance, we get Distance = sqrt((4)^2 + (6)^2) = sqrt(16 + 36) = sqrt(52) = 2 sqrt(13).
prove that cos^2A+sin^2A.cos2B=cos^2B+sin^2B.cos2A
Notice that both sides of the equation have a similar form. If we ignore angle functions we end up with,
[tex]A+A\cdot B=B+B\cdot A[/tex]
That is true if condition [tex]A=B[/tex] is met.
Otherwise it is false.

Georgia filled her kitchen sink up with water so that she could do the dishes. When she was done with the dishes, she pulled out the drain stopper so the water could begin to drain out of the sink.
A linear model of this situation contains the values (2, 8.4) and (4, 7.8), where x represents the number of seconds, and y represents the water level in the sink, in inches.
What is the rate of change in this linear model?
A.
-0.3 of an inch per second
B.
0.3 of an inch per second
C.
-9 inches per second
D.
-0.6 of an inch per second
Answer:
A) -0.3 of an inch per second
Step-by-step explanation:
You'll have to put (2, 8.4) and (4, 7.8) into the slope formula.
It's represented as (∆y)/(∆x) = m
(y1 + y2)/(x1 + x2) = m
You subtract both y's in the numerator and subtract both x's in the denominator.
Like this:
(8.4-7.8)/(2-4) = m
(0.6)/(-2) = m
-0.3 = m
Answer:
y = (-0.3 in/sec)x + 9.0 in
Step-by-step explanation:
(2, 8.4) and (4, 7.8) are points on a linear graph.
As we go from (2, 8.4) to (4, 7.8), x increases by 2 and y decreases by 0.6.
Thus, the slope of the line is m = rise / run = -0.6 / 2, or m = -0.3 inches/sec
Let's use the slope-intercept form of the equation of a straight line, with m = -0.3 in/sec and one point being (2, 8.4).
Then y = mx + b becomes 8.4 = (-0.3 in/sec)(2) + b, or
8.4 = -0.6 + b. Thus, b = 9.0, and the desired equation is thus:
y = (-0.3 in/sec)x + 9.0 in

According to Vinay's model, what is the probability that he will have a male history teacher two years in a row?
1. 3/8
2. (3/8)(2)
3. (3/8)^(2)
4. 3/(8)^(2)
Answer:
(3/8) ^2
Step-by-step explanation:
P ( male history teacher) = Number males/ total
= 3/8
Assuming nothing changes in year two
P ( male history teacher year two) = Number males/ total
= 3/8
P( male, male) = 3/8 * 3/8 = (3/8) ^2
(3/8)^2 would be your answer.
Since there are 3 male and 5 female, that means there are 3/8 male and 5/8 female. We are talking about male and how many times it would happen in 2 years, so (3/8)^2 would be your answer.
Find the equation for the line that passes through the point (−2,0), and that is perpendicular to the line with the equation 2/3x+y=−14/3.
Answer:
y = 3/2 x + 3
Step-by-step explanation:
2/3 x + y = -14/3
y = -2/3 x − 14/3
The slope of this line is -2/3. So the perpendicular slope is the opposite of the inverse:
m = -1 / (-2/3)
m = 3/2
We know the slope of the line and a point on the line, so using point-slope form:
y − 0 = 3/2 (x − (-2))
Simplifying into slope-intercept form:
y = 3/2 (x + 2)
y = 3/2 x + 3
Find a ⋅ b. a = 4i - 4j, b = 4i + 5j
Answer:
value of a.b = -4
Step-by-step explanation:
We need to find a.b
a= 4i-4j
b = 4i+5j
We know that i.i =1, j.j=1, i.j =0 and j.i=0
a.b = (4i-4j).(4i+5j)
a.b = 4i(4i+5j)-4j(4i+5j)
a.b = 16i.i +20i.j-16j.i-20j.j
a.b = 16(1) +20(0)-16(0)-20(1)
a.b = 16 +0-0-20
a.b = 16-20
a.b =-4
So, value of a.b = -4

factor 15x^3-6x^2-25x+10 by grouping
Answer: (5x-2)(3^2-5)
Step-by-step explanation:
So using the commutative property, we can change the equation 15x^3-6x^2-25x+10 into 15x^3-25x -6x^2+10
Let’s split that into two sections so it’s easier to see:
(15x^3-25x) - (6x^2+10)
Next let’s look at what 15x^3 and -25x have in common. They have 5x in common.
Factoring out 5x, we get this: 5x(3^2-5)
Next let’s look at what -6x^2and 10 have in common. They only have 2 in common, so we factor out 2.
2(-3^2+5) we can write this as -2(3^2-5)
So the end result will be : 5x(3^2-5)-2(3^2-5)
And the complete factorization will be (5x-2)(3^2-5)

Triangle JKL is translated using (x, y) --> (x + 1, y - 3) after it is reflected across the x-axis. What are the
coordinates of the final image of point under this composition of transformations?
help please
Answer:
(1, - 6 )
Step-by-step explanation:
Under a reflection in the x- axis
a point (x, y ) → (x, - y )
The point J has coordinates (0, 3 ), hence
J'(0, - 3 ) ← after reflection in x- axis
A translation (x, y ) → (x + 1, y - 3 )
Means add 1 to the x- coordinate and subtract 3 from the y- coordinate
J'(0, - 3 ) → J''(0 + 1, - 3 - 3 ) → J''(1, - 6 ) ← final image

Answer:
Choose something close to (1.8,2.6)
Choice A
Step-by-step explanation:
Without the graph provided, I would prefer to do this algebraically.
y=2x-1
y=-1/4x+3
Since both are solved for y, I'm going to replace the first y with what the second y equals.
-1/4x+3=2x-1
I don't really like to deal with fractions quite yet so I'm going to multiply both sides by 4.
-1x+12=8x-4
I'm going to add 1x on both sides.
12=9x-4
I'm going to add 4 on both sides.
16=9x
I'm going to divide both sides by 9
16/9=x
This is the same as saying x=16/9.
Now to find y, just choose one of the equations and replace x with 16/9.
y=2x-1
y=2(16/9)-1
y=32/9-1
y=32/9-9/9
y=(32-9)/9
y=23/9
So the exact solution is (16/9,23/9).
Round these numbers to the nearest tenths you get:
(1.8, 2.6) .
To get this I just typed into my calculator 16 divided by 9 and 23 divided by 9
16 divided by 9 gave me 1.777777777777777777777777777
23 divided by 9 gave me 2.5555555555555555555555555
So choose something close to (1.8, 2.6).
So your ordered pair (1.75,2.5) is pretty close to that so choice A.
Help with substitution! (With pictures-2 separate questions) thanks!
Answer:
Explanation contains answer.
Step-by-step explanation:
Question 1:
I would perfer to solve the first equation for y because there is only one operation to perform on both sides and it is subtraction of 2x on both sides.
The other equation requires two steps to isolate y; subtracting 3x on both sides then multiplying both sides by -1.
So basically solving the first one for y because it has coefficient 1.
Question 2:
They solved the 2nd equation for y and plugged into itself instead of plugging it into 1st equation.
what is the value of x?
x= 2.25
x= 11.25
x= 13
x= 22
For this case we have that by definition, the sum of the internal angles of a triangle is 180 degrees.
Then, according to the figure we have:
[tex][180- (6x + 1)] + 79+ (2x + 10) = 180[/tex]
We operate parentheses:
[tex]180-6x-1 + 79 + 2x + 10 = 180[/tex]
We add similar terms:
[tex]-4x + 268 = 180\\-4x = 180-268\\-4x = -88\\x = \frac {-88} {- 4}\\x = 22[/tex]
Thus, x has a value of 22 degrees.

[tex]x = \frac {-b \pm \sqrt {b ^ 2-4 (a) (c)}} {2 (a)}[/tex]
We have to:
[tex]a = 1\\\b = 3\\c = -3[/tex]
So:
[tex]x = \frac {-3 \pm \sqrt {3 ^ 2-4 (1) (- 3)}} {2 (1)}\\x = \frac {-3 \pm \sqrt {9 + 12}} {2}\\x = \frac {-3 \pm \sqrt {21}} {2}[/tex]
We have two roots:
[tex]x_ {1} = \frac {-3+ \sqrt {21}} {2} = 0.7913\\x_ {2} = \frac {-3- \sqrt {21}} {2} = - 3.7913[/tex]
Answer:
[tex]x_ {1} = \frac {-3+ \sqrt {21}} {2} = 0.7913\\x_ {2} = \frac {-3- \sqrt {21}} {2} = - 3.7913[/tex]
Which of the following is the correct graph of the solution to the inequality-18>-5x+2>-48
Answer:
Step-by-step explanation:
we have
[tex]18 > -5x+2 > -48[/tex]
This is a compound inequality
Remember that
A compound inequality i can divide in a system of two inequalities
so
[tex]18 > -5x+2[/tex] -----> inequality A
[tex]-5x+2 > -48[/tex] ---> inequality B
step 1
Solve the inequality A
[tex]18 > -5x+2[/tex]
Multiply by -1 both sides
[tex]-18< 5x-2[/tex]
[tex]-18+2< 5x[/tex]
[tex]-16< 5x[/tex]
Divide by 5 both sides
[tex]-3.2< x[/tex]
Rewrite
[tex]x > -3.2[/tex]
The solution of the inequality A is the interval ----> (-3.2,∞)
step 2
Solve the inequality B
[tex]-5x+2 > -48[/tex]
Multiply by -1 both sides
[tex]5x-2 < 48[/tex]
[tex]5x < 48+2[/tex]
[tex]5x < 50[/tex]
Divide by 5 both sides
[tex]x < 10[/tex]
The solution of the inequality B is the interval ----> (-∞, 10)
step 3
Find the solution of the compound inequality
(-3.2,∞) ∩ (-∞, 10)=(-3.2,10)
All real numbers greater than -3.2 and less than 10
