Calculate the volume of this prism
Answer:
800 cm³
Step-by-step explanation:
The volume is the product of the base area and the "height" of the prism. Here, the base can be considered to be a 10 cm × 12 cm rectangle with a 4 cm × 5 cm cutout. Its area will be ...
A = (10 cm)(12 cm) -(4 cm)(5 cm) = 120 cm² -20 cm² = 100 cm²
The product of this base area and the 8 cm height of the prism is ...
V = Bh = (100 cm²)(8 cm) = 800 cm³
The volume of the prism is 800 cm³.

What is the slope of line a?
Answer:
1/3
Step-by-step explanation:
The slope of a line represents the variation in height per variation in length.
In our case, for every square you move up, you have to move 3 horizontally. The slope is thus
m= (vertical change) / (horizontal change) = 1/3
Answer:
1/3

What is the answer
Answer:
73.12 in.²
Step-by-step explanation:
The entire area is made up of a semicircle and a rectangle. We find both areas and add them.
total area = area of semicircle + area of rectangle
total area = (1/2)πr² + length × width
total area = 1/2 × 3.14 × 4 in. × 4 in. + 8 in. × 6 in.
total area = 73.12 in.²

The quadratic function, f(x )or g(x) has the greater maximum value ??
Answer:
The quadratic function, f(x) has the greater value.
Step-by-step explanation:
The given function written to us is in standard form, meaning it is easy to graph this function.
Since this function is going to open down-ward, we start with negative numbers.
[tex]f(-1)=3\\[/tex]
Since 3 is a greater value than 2, which we can see is the maximum value of g(x) by viewing the graph, f(x) is greater.
45:60 as its simplest form
Answer :
3/4.
Explanation
Find the GCD (or HCF) of numerator and denominator
GCD of 45 and 60 is 15
Divide both the numerator and denominator by the GCD
45 ÷ 15
60 ÷ 15
Reduced fraction: 3/4
Therefore, 45/60 simplified to lowest terms is 3/4.
Hi! I hope you are enjoying your day!
In order to simplify this ratio (and 45:60 is a ratio), we should divide both sides of the ratio by 5 (because both 45 and 60 are evenly divisible by 5)
Divide:
9:12
Is the ratio in its simplest form? No.
Why?
Because 9 and 12 can be divided by 3:
3:4
Now the ratio IS in its simplest form.
Hence, the answer is
[tex]\boxed{\boxed{\bold{3:4}}}[/tex]
Hope everything is clear.

First of all, the G.C.F. stands for
Greatest Common Factor
So we need to find the Greatest Common Factor of the polynomials.
And yea, polynomials have Greatest Common Factors as well.
So, let's find all the Greatest Common Factors. :)
First, we have
[tex]\bold{28x^2yz}[/tex] and [tex]\bold{16xy^2}[/tex]
What are the common factors of these polynomials?
Well, there are plenty of them, like 2, 2x, y...
What is the Greatest Common factor?
Is it Option A, 12xy?
No, because neither 28 nor 16 is divisible by 12.
So we cross out Option A.
Is it Option B, 8xy?
No, because 28 isn't divisible by 8, and remember, if a number is evenly divisible by another number, then that number is a factor.
Example: 8 is a factor of 16 (16÷8=2); 8 is not a factor of 28, because
28÷8=3.5 (a decimal, not a whole number)
Is it Option C, 4xy?
Yeah, it seems like Option C is the right option.
[tex]\huge\checkmark[/tex]Both 28 and 16 are divisible by 4
[tex]\huge\checkmark[/tex]Both polynomials have an x and a y in them
[tex]\rule{250}{2}[/tex]
Find the GCF:
[tex]\bold{5x^2y^4,\:10x^3y^5, \:and\:15xy^2}[/tex]
Once again, is it Option A, 5x^3y^5?
No, because
✘ 5 and 10 aren't divisible by 3
✘ None of the 3 polynomials has a 3y term
In other words, Option A is wrong.
How about Option B?
You should see right off the bat that 5 and 15 aren't divisible by 10.
So now we have 2 options left.
Is it Option C, 5xy²?
Well,
✓All 3 polynomials are divisible by 5
✓ All 3 polynomials have a y² term
✓ All 3 polynomials have an x term.
Hence, the answers are
[tex]\boxed{\boxed{\bold{1. \;Option\;C; 2.\;Option\;C.}}}[/tex]
Hope everything is clear.

Find the zeros of the function f (x) = 4x^2-16
Answer:
x=-2
x=2
Step-by-step explanation:
We can think of this equation like a statement
"4 times what squared minus sixteen is equal to zero"
First, we need to rearrange the equation:
[tex]4x^2=16[/tex]
Now using our common knowledge, we know that 4 times 4 is equal to 16
now we have another statement:
"x times x is going to be equal to 4"
*Remember that the two numbers have to be the same since x is squared*
Again, we can use common knowledge and say that 2x2 is equal to 4
This means that x=2
Now when you square a variable, the variable can have to values, a positive, and a negative value
So in this case, the other value for x would be x=-2 since -2 squared is also equal to 4
So we can come to a conclusion that
x=2
AND
x=-2

The slope-intercept form of an equation of a line: y=mx+b
m - slope
b - y-intercept
We have the points (5, -4) and (-1, 8). Substitute:
m= [tex]\frac{8-(-4)}{-1-5}[/tex] =[tex]\frac{12}{-6}[/tex] =-2
Put the value of the slope and the coordinates of the point (5, -4) to the equation of a line,
-4=-2(5)+b
=-10+b
6=b
y=2x+6

Sarah has two sets of cards. The first set of 26 cards is labeled with all the letters of the English Language. The second set of 10 cards is numbered 0 through 9.
If Sarah draws one lettered card and one numbered card at random, what is the probability of her drawing a letter in her name and an odd number? (Enter answer as a reduced fraction).
Answer:
1/13
Step-by-step explanation:
Probability of Sarah drawing a letter in her name
= number of letters in her name: S, A, R and H / total number of letters
= 4/26
Probability of drawing an odd number
= odd numbers / total numbers
= 5/10
Combining the above, Probability of her drawing a letter in her name and an odd number = 4/26 * 5/10
= 1/13
Total Alphabetical cards Sarah has ⇢ 26
Total Letters Sarah's name has ⇢ 4
Probability of getting a card with one of the letter in her name ⇢ 4/26
Total numerical Cards Sarah has ⇢ 10
Total odd numbers in those cards⇢5
Probability of getting a card with an odd number⇢ 5/10
probability of her drawing a letter in her name and an odd number⇢ 4/26 x 5/10 = 1/13
The total remodeling budget for Central Square Tower is 1.5×106 dollars. The owners of the building have set aside 6×105 dollars for upgrading just the lobby. What percent of the budget will be spent on the lobby? Write your answer in standard form. Do not write exponents.
Answer:
40%
Step-by-step explanation:
assuming you actually mean 10^5 and 10^6, to find percentages you do
part/total x percent/100
you have (6x10^5/1.5x10^6) x (x/100)
cross multiply, and you have 6x10^7=1.5x10^6x
divide on both sides by 1.5x10^6
x=40
so the answer is 40%
