Answer:
676pi units ^2
Step-by-step explanation:
apex
The surface area of a sphere with a radius of 13 units is 676π²
What is surface area?explaination;
Given radius = 13 units
surface area of a sphere = 4πr²
= 4 * 13*13 π²
676π² answer.
The surface area is the sum of the areas of all its faces.The areas of the base, top, and lateral surfaces i.e all sides of the object. It is measured using different area formulas and measured in square units and then adding all the areas. The surface area of a solid object is a measure of the total area that the surface of the object covers.The floor region of a strong object is a measure of the full vicinity that the floor of the item occupies. The mathematical definition of surface vicinity within the presence of curved surfaces is extensively extra involved than the definition of arc length of 1-dimensional curves, or of the floor area for polyhedra for which the surface place is the sum of the areas of its faces. clean surfaces, such as a sphere, are assigned floor region using their representation as parametric surfaces. The definition of floor area is based totally on methods of infinitesimal calculus and includes partial derivatives and double integration.

Which graph below shows a system of equations with infinitely many solutions?
A)coordinate plane with two parallel lines
B)coordinate plane with two intersecting lines
C)coordinate plane with two coinciding lines
D)coordinate plane with two intersecting lines
Answer:
The correct option is C.
Step-by-step explanation:
Consider the provide information.
Now consider the provided options
Option A) If there is a coordinate plane with two parallel lines.
if the plane has two parallel line then, It has no solution because you can get the solution if lines intersect at a point. Thus, it is not the required option.
Option B) and D) If there are two intersecting lines then you can get only one solution. Thus, it is not the required option.
Option C) If there are two coinciding lines then you can find infinite intersecting points. Thus, it is the required option.
Therefore, the correct option is C.

Solve for y.
4y = 144
What is the answer?
The solution is y = 36. Divide both sides of the equation by 4 to isolate y. To isolate y, we want to get rid of the coefficient 4 that is multiplying y.
We do this by dividing both sides of the equation by 4:
4y / 4 = 144 / 4
On the left side, the 4 in the numerator and the 4 in the denominator cancel out, leaving us with just y:
y = 144 / 4
Now, Simplify the equation.
Now, we can perform the division to find the value of y:
y = 36
The solution is y = 36.

Max spent $53 and now has no money left. How much did he have before his purchase
An equation is formed when two equal expressions. The amount Max had before his purchase is $53.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Given that Max spent $53 and now has no money left. Therefore, we can write the details as,
The amount spent on the purchase = $53
The amount left after purchase = $0
Let the amount before purchase be represented by M. Therefore, we can write the amount remaining after purchase as,
Amount before purchase - Amount spent on purchase = Amount remaining after purchase
M - $53 = $0
Adding 53 on both sides.
M - 53 + 53 = 53
M = 53
M = $53
Thus, the amount Max had before his purchase is $53.

5.horizontal shrink by a factor of 1/4
6.horizontal stretch by a factor of 4

When you negate f(x) to get g(x) = -f(x), it reflects the graph of f(x) in the x-axis.
So, the correct answer is: 3. Reflection in the x-axis

Luis has a $10 bill and three $5 bills. He spends $12.75 on the entrance fee to an amusement park and $8.50 on snacks. How much money doe she have left
Answer:
She has a total of $3.75 left
Step-by-step explanation:
Step 1
Express the amount of money Luis had in the beginning as follows;
A=E+R
where;
A=initial amount he had at the beginning
E=total expenditure
R=total remainder after spending
In our case;
A=(1×10)+(3×5)=$25
E=Amount spent at amusement park+amount spent on snacks
E=(12.75+8.50)=$21.25
R=unknown=r
Step 2
Substitute the values in the expression and solve for A;
25=21.25+r
r=25-21.25=3.75
r=3.75
She has a total of $3.75 left

Eleven less than seven times a number is five more than six times the number.
The problem is a simple algebraic equation in the form 7x - 11 = 6x + 5. By rearranging and simplifying, we find the solution is x = 16.
Explanation:The question presents a mathematical statement that needs to be solved for the variable. Translating the words into an equation, we get: 7x - 11 = 6x + 5. This equation is saying seven times a number (we'll call it 'x') reduced by eleven is equal to six times that number increased by five.
To solve for 'x', first, rearrange the equation to get all 'x' terms on one side and constants on the other. By subtracting 6x from both sides, we get x - 11 = 5. Then, add 11 to both sides to isolate 'x': x = 16.
So, the number or 'x' that satisfies this equation is 16.

x = 16.
To solve this, let the unknown number be represented by x.
We can set up the equation based on the given information:
7x - 11 = 6x + 5
Subtract 6x from both sides of the equation:
7x - 6x - 11 = 6x - 6x + 5
Simplify the equation:
x - 11 = 5
Add 11 to both sides:
x - 11 + 11 = 5 + 11
Simplify the equation:
x = 16
Thus, the number is 16.
find the coordinates of the midpoint of EF with endpoints E(-2,3) and F(5, -3)
The coordinates of the midpoint of line segment EF with endpoints E(-2,3) and F(5, -3) are (1.5, 0), calculated using the midpoint formula.
To find the coordinates of the midpoint of line segment EF with endpoints E(-2,3) and F(5, -3), you can use the midpoint formula which is:
( (x1 + x2)/2, (y1 + y2)/2 )
Let's apply the formula:
x-coordinate of midpoint = ( (-2) + 5 ) / 2 = 3 / 2 = 1.5
y-coordinate of midpoint = ( 3 + (-3) ) / 2 = 0 / 2 = 0
So the midpoint of EF is (1.5, 0).
What is the area of a rectangle with vertices at (−3, −1) , (1, 3) , (3, 1) , and (−1, −3) ? Enter your answer in the box. Do not round any side lengths.
∠C and ∠D are vertical angles with m∠C=−x+26 and m∠D=2x−10 . What is m∠D ? Enter your answer in the box.
Answer:
m∠D=14
Step-by-step explanation:
∠C and ∠D are vertical angles with m∠C=−x+26 and m∠D=2x−10
Vertical angles are equal. So equate the angles C and d . Solve for x
m∠C=m∠D
[tex]-x+26=2x-10[/tex]
Subtract 2x from both sides
[tex]-3x+26=-10[/tex]
Subtract 26 from both sides
[tex]-3x=-36[/tex]
Divide both sides by -3
x=12
m∠D=2x−10
Substitute 12 for x
m∠D=2(12)−10=24-10= 14

Give an estimate for 42.8 x 13.6
Final answer:
A reasonable estimate for the product of 42.8 x 13.6 is 602, achieved by rounding each number to the nearest whole number and then multiplying them together.
Explanation:
To estimate the product of 42.8 x 13.6, we can round each number to the nearest whole number and then multiply. So, 42.8 is approximately 43, and 13.6 is approximately 14. Now, multiply these estimated values.
Estimated Calculation:
43 x 14 = 602
Therefore, a reasonable estimate for the product of 42.8 and 13.6 is 602. Remember, in estimation, we aim to simplify the calculation while still arriving at a number that's close to what the actual answer would be if we calculated it exactly.

Ron works 5 hours for a total of $300. He deposits all of his money in his account. He is trying to save a $500 for a new LED TV. How many hours must he work to ake home $500, if he saves all of his earnings
Ron's hourly wage is $60. To save $500 for a new LED TV, he needs to work approximately 8.3 hours. Rounding up, he should work 9 hours to earn the required amount.
Ron earns $300 for working 5 hours, which means his hourly wage is $300 / 5 hours = $60 per hour. To save up for a $500 LED TV, Ron needs to determine how many hours he must work to earn that amount.
To calculate the total hours Ron needs to work to save $500, we divide the total amount he wants to save by his hourly wage:
$500 ÷ $60 per hour = 8.3 hours
Therefore, Ron needs to work approximately 8.3 hours to earn $500, assuming he continues to save all of his earnings. In practice, since he cannot work a fraction of the hour, Ron would need to round up to the nearest whole hour, meaning he needs to work 9 hours to meet or exceed his savings goal.
