A hundredth is 0.01
A hundred is 100.
You look at the digital to the right of the 1, in the example above. If that digit is 5 or greater, round up, other round down.
In both cases, you will look at the 0, therefore you would round down.
1800 to the nearest hundredth is 1800.00.
1800 to the nearest hundred is 1800.

Answer
B=36.
Explanation
L.s.f=linear scale factor.
A.s.f=area scale factor.
L.s.f=length of prism 1/length of prism 2
L.s.f=3/8.
let area or prism 1=x
A.s.f=(L.s.f)^2
A.s.f=(3/8)^2
=9/64
9/64=x/256
x=(9×256)÷64
=36.

Julie can type 3 pages in x minutes. How many minutes will it take her to type 11 pages?
a. 33x
b. 3/ 11x
c. 11/ 3x
d. 3x/ 11
e. 11x /3
Julie can type 3 pages in x minutes; to find the time to type 11 pages, set up a proportion and solve, resulting in 11x/3 minutes.
Explanation:Since Julie can type 3 pages in x minutes, the rate at which Julie types is 3 pages per x minutes. If we want to find out how many minutes it will take her to type 11 pages, we simply set up a proportion based on her typing rate:
3 pages / x minutes = 11 pages / y minutes
To solve for y, which is the time it will take to type 11 pages, we cross-multiply and get:
3y = 11x
Then, we divide both sides of the equation by 3, yielding:
y = 11x / 3
The answer is option (e): 11x / 3.

Find the length of AC. Express your answer in terms of pi.
Answer options: 5, 30, 45, 15.
Answer:
The correct answer is 3πcm
Step-by-step explanation:
The length of an arc is calculated using the formula P=∅/360×2πr
where ∅is the angle the arc subtends at the center of the circle, and r is the radius of the circle of which the arc is part.
2r gives the diameter which from the diagram corresponds to AB=36 cm
therefore P=30/360×π×36
=3πcm
5pi is the answer

155% of what number is 44?
Answer:
28.4
Step-by-step explanation:
Translate the statement into an equation, and then solve the equation.
Let x be the number we are looking for.
155% of what number is 44?
155% of x is 44
In math "of" usually means multiplication.
155% * x = 44
To change a percent to a decimal, divide by 100 which means move the decimal point 2 places left. 155% = 155/100 = 1.55
1.55x = 44
Divide both sides by 1.55 to solve for x.
1.55x/1.55 = 44/1.55
x = 28.4

What is the perimeter of the triangle shown on the coordinate plan to the nearest tenth of a unit? Please help me. I don’t think my answer is correct.
the perimeter of the triangle shown on the coordinate plane to the nearest tenth of a unit is 21 units. Therefore, option c is the correct answer.
To find the perimeter of the triangle shown on the coordinate plane, we need to calculate the lengths of each side and then add them together.
Step 1: Calculate the length of the first side.
Using the distance formula, the length of the side connecting (-3, 3) and (3, -3) is:
√[(3 - (-3))^2 + (-3 - 3)^2] = √[6^2 + (-6)^2] = √[36 + 36] = √72.
Step 2: Calculate the length of the second side.
Using the distance formula, the length of the side connecting (3, -3) and (3, 3.5) is:
√[(3 - 3)^2 + (3.5 - (-3))^2] = √[0^2 + 6.5^2] = √[0 + 42.25] = √42.25.
Step 3: Calculate the length of the third side.
Using the distance formula, the length of the side connecting (3, 3.5) and (-3, 3) is:
√[(-3 - 3)^2 + (3 - 3.5)^2] = √[-6^2 + (-0.5)^2] = √[36 + 0.25] = √36.25.
Step 4: Calculate the perimeter by adding the lengths of the sides.
Perimeter = √72 + √42.25 + √36.25.
Now we can simplify the answer to the nearest tenth:
Perimeter ≈ 8.5 + 6.5 + 6 = 21.
Therefore, the perimeter of the triangle shown on the coordinate plane to the nearest tenth of a unit is 21 units.
Therefore, option c is the correct answer.

Solve the following system of equations.
-3x + 5y =85
x + 4y =34
A. x = 2, y = 18.2
B. x = 11, y = -10
C. x = -10, y = 11
D. x = 8, y = 6.5
Answer: option C
[tex]x=-10\\y=11[/tex]
Step-by-step explanation:
You can apply the elimination method:
- Multiply the second equation by 3.
- Add both equations to cancel out the variable x.
- Solve for y:
[tex]\left \{ {{-3x+5y=85} \atop {(3)(x+4y)=34(3)}} \right.\\\\\left \{ {{-3x+5y=85} \atop {3x+12y=102}} \right.\\-------\\17y=187\\y=11[/tex]
- Substitute y=11 into any of the original equations ans solve for x. Then:
[tex]x+4(11)=34\\x=34-44\\x=-10[/tex]
The answers are:
[tex]x=-10\\y=11[/tex]
Why?We can solve system of equations using several methods, but the simplest way to solve it, is isolating variables in terms of another variables.
So, isolating "x" from the second equation we have:
[tex]x + 4y =34\\x=34-4y[/tex]
Then, substituting "x" into the first equation, we have:
[tex]-3(34-4y) +5y =85\\-102+12y+5y=85\\17y=85+102\\17y=187\\y=\frac{187}{17}=11\\[/tex]
Now, substituting "y" into the second equation to calculate "x", we have:
[tex]x + 4(11) =34\\x=34-44\\x=-10[/tex]
So, the solutions for the system of equations are:
[tex]x=-10\\y=11[/tex]

Compare the algebraically expressed function f(x) = - 5 2 x2 - 8x to the function shown in the graph to determine which statement is true. A) The algebraic function has a greater maximum value. B) The algebraic function has a lower minimum value. C) The graphed function has a greater maximum value. D) The graphed function has a lower minimum value.
After evaluating the given information about the algebraic and graphed functions, we can conclude that the algebraic function f(x) = -5x^2 - 8x, which is a downward-opening parabola, has a greater maximum value than the graphed function in question. Therefore, the correct answer is option A.
Explanation:To compare the algebraically expressed function f(x) = -5x^2 - 8x with a given graphed function, we need to look at their respective shapes and key features. Since f(x) is a quadratic function with a negative coefficient for the x^2 term, it is a downward-opening parabola that will have a maximum value. Without more information about the graphed function, we can still analyze the given description to ascertain its nature.
Based on the given statements, let's identify which function has a greater maximum or a lower minimum value:
A graphed function represented as a horizontal line from x = 0 to x = 20 implies a constant function with the same value across this interval, and therefore it cannot have a greater maximum or lower minimum value than any other function.Option 75 suggests a function with a positive value and positive slope decreasing with increasing x which would not have a maximum value given it's continuously increasing.The given declining curve with a positive value at x = 0 indicates a decaying exponential function. Its maximum value is at x = 0 since the function is decreasing as x increases, making statement B an appropriate comparison.Lines that are increasing or decreasing in steepness don't provide clear information about their maximums or minimums without additional context.In conclusion, given that f(x) = -5x^2 - 8x is a downward-opening parabola with a definite maximum value, and none of the provided statements about the graphed function suggest it has a maximum value higher than a constant value or a parabola, we can conclude that:
The algebraic function has a greater maximum value, so the correct answer would be option A.
The graphed function has a greater maximum value. The algebraic function's downward-opening parabola indicates a maximum value, and the graphed function's characteristics suggest it may have a higher maximum (option c).
Explanation:To determine the maximum values of the algebraic function [tex]\(f(x) = -\frac{5}{2}x^2 - 8x\)[/tex] and the graphed function, we need to analyze the coefficient of the quadratic term in the algebraic expression. The quadratic term is [tex]\(-\frac{5}{2}x^2\)[/tex], and since the leading coefficient is negative, the parabola opens downwards. This means that the algebraic function has a maximum value, and the coefficient [tex]\(-\frac{5}{2}\)[/tex] determines the concavity.
Comparatively, the graphed function on the graph may have a different leading coefficient, affecting the concavity. If the graphed function has a positive leading coefficient, it opens upwards, suggesting a minimum value. Conversely, if it has a negative leading coefficient, it opens downwards, indicating a maximum value (option c).
In the case of the given options, statement C is correct. The graphed function has a greater maximum value because the leading coefficient of the quadratic term in the algebraic function is negative, resulting in a downward-opening parabola with a maximum point. Therefore, the graphed function, depending on its characteristics, may exhibit a greater maximum value.
The complete question of the given answer is:
Compare the algebraically expressed function [tex]\(f(x) = -\frac{5}{2}x^2 - 8x\)[/tex] to the function shown in the graph to determine which statement is true.
A) The algebraic function has a greater maximum value.
B) The algebraic function has a lower minimum value.
C) The graphed function has a greater maximum value.
D) The graphed function has a lower minimum value."
If A ⊂ B, then A ∩ B = A ∪ B.
always
sometimes
never
Answer: Third option.
Step-by-step explanation:
A ⊂ B this means that A is subset of B.
If A is subset of B (A ⊂ B), then all the elements of A belong to the subset B.
For example, the set of the Natural numbers is a subset of the Real Numbers.
Then, A ∩ B are all the elements that belong to AB at the same time.
A ∪ B are all the elements of A and all the elements of B.
But if we already said that A is inside of B, then:
A ∩ B = A ≠ A ∪ B
A ∩ B = A ∪ B only happen when the set A=set B.
Therefore, the answer is: NEVER.
