Answer:
Volume = 66
Surface are = 144
Step-by-step explanation:
1. Volume
The formula to find the volume of a triangular prism is the following,
[tex]A=\frac{l*w*h}{2}[/tex]
The following information is given,
lenght = 4
width = 11
hieght = 3
Substitute these numbers into the formula and solve for the heihgt,
[tex]A=\frac{l*w*h}{2}\\\\A=\frac{4*11*3}{2}\\\\A=66[/tex]
2.Surface area
The surface area of a figure is the two-dimensional distance around the figure. It can be found by finding the area of each face of the figure and then adding the result up.
The formula to find the area of a rectangle is the following,
[tex]A_r=(lenght)(width)[/tex]
The formula to find the area of a triangle is the following,
[tex]A_t=\frac{(legnth)(width)}{2}[/tex]
Substitute in the give values and add up the results to find the total surface area of the rectangle,
[tex]((5)(11))+((4)(11))+((3)(11))+(\frac{(3)(4)}{2})+(\frac{(3)(4)}{2})\\\\=55 + 44 + 33+ 6 + 6\\\\= 144[/tex]

Find the missing dimensions
Answer:
short base: 6 yards
long base: 8 yards
Step-by-step explanation:
Our understanding of your figure is shown below.
The question says the "shortest side" and the "width" have the same dimension. If the "width" is a reference to "height 6 yards", then it seems the "shortest side" is 6 yards. Since the slant sides are longer than the height, the "shortest side" is also the "short base."
The short base is 6 yards.
__
The long base overhangs the short base by 1 yard on either end, so it is a total of 2 yards longer than the short base. It it 6+2 = 8 yards long.
The long base is 8 yards.

Simplify the expression by combining like terms: x + 7x
Answer:
Like terms means that the numbers have the same variable after them or they don't have a variable at all. It is also important to remember that any letter that doesn't have a number in front of it technically has a 1 in front of it.
For example, x + 3x = 1x +3x. Then I add the numbers in the front and I get 4x.
If it had been 4x + 7x + 3, my answer would have been 11x +3. That's because there were a total of 11 x, but the 3 ones weren't x's so I just leave them alone.
Step-by-step explanation:
Answer:
[tex]8x[/tex]
Step-by-step explanation:
[tex]x+7x[/tex]
[tex]8x[/tex]
The answer is [tex]8x[/tex] when you simplify because you are adding another [tex]x[/tex] to [tex]7x[/tex] so it becomes [tex]8x[/tex]

The area of the base of a right square pyramid is multiplied by 5, but the height is unchanged. What is the volume of the new pyramid divided by the volume of the original pyramid?
9514 1404 393
Answer:
5
Step-by-step explanation:
The volume of a right square pyramid is given by the formula ...
V = 1/3Bh
where B is the area of the base.
The volume of the larger pyramid will be ...
V' = 1/3(5B)h
So, the ratio of volumes is ...
V'/V = (1/3(5B)h)/(1/3Bh)
V'/V = 5
The ratio of volumes is 5.

(4b^2+3)(4b^2-3)
Answer:
16b^4-9
Step-by-step explanation:
Factoring gives us 16b^4+12b^2-12^2-9. Simplifying gives us the answer which is 16b^4-9
Answer:
[tex]16b^4-9[/tex]
Step-by-step explanation:
When multiplying binomials, we can use a method called FOIL (First-Outside-Inside-Last).
For [tex](t_1+t_2)(t_3+t_4)[/tex], let:
[tex]t_1\implies \text{First Term},\\t_2\implies \text{Second Term},\\t_3\implies \text{Third Term},\\t_4\implies \text{Fourth Term}[/tex]
In the FOIL method, the steps go:
[tex]\text{\textbf{F}irst: Multiply the first and third terms (first term of each binomial)},\\\text{\textbf{O}utside: Multiply the first and fourth terms},\\\text{\textbf{I}nside: Multiply the second and third terms},\\\text{\textbf{L}ast: Multiply the second and fourth terms (last term of each binomial) }[/tex]
Given [tex](4b^2+3)(4b^2-3)[/tex], we have:
[tex]\text{First: }4b^2\cdot 4b^2,\\\text{Outside: }4b^2\cdot -3,\\\text{Inside: }3\cdot 4b^2,\\\text{Last: }3\cdot -3,\\\rightarrow 16b^4-12b^2+12b^2-9[/tex]
Combine like terms:

Pat threw a football 5 more than twice the number of yards, y, which Gary threw. Which expression can be used to find the number of yards Pat threw the football? *
**SHOW WORKK PLS
Answer:
2y+5
Step-by-step explanation:
Lets start with an expression for how many yards Gary threw. Since y is the variable given in the problem, we'll use that.
Yards Gary threw = y
We also know that Pat threw 5 more than twice the yards Gary did. First, we multiply Gary's yards by 2, then add 5 more. We end up with the expression:
Yards Pat threw = 2y+5

The ratio of the number of cups of red paint to the number of cups of yellow paint that Garcia mixed to make a shade of orange paint is 4:1.
Part A: Write a sentence to describe the number of cups of red paint that Garcia mixed with each cup of yellow paint. (4 points)
Part B: How many cups of yellow paint should Garcia add to each cup of red paint to make the shade of orange? Explain your reasoning. (4 points)
Part C: If Garcia purchased 6 cups of red paint for $42, what is the unit price per cup of red paint? (2 points)
Part A: Garcia mixed 4 cups of red with 1 cup of yellow.
Part B: 1/4 because 4 cups of red requires 1 cup of yellow, so 1 divided by 4 is 1/4.
Part C: $7
Hope this helps! :)
The unit price for a cup of red paint is equal to $7
What is the unit rate?Unit rate is the ratio of two different units, with denominator as 1. For example, kilometer/hour, meter/sec, miles/hour, salary/month, etc. Arithmetic is probably the most basic and ancient branch of mathematics and is quite commonly used in our day-to-day life.
Given here: The ratio of the number of cups of red paint to the number of cups of yellow paint that Garcia mixed to make a shade of orange paint is 4:1
For every yellow cup of paint Garcia mixed 4 cups of red paint to the mixture.
Now the ratio given here is 4:1
Thus for every 1 cup of yellow paint garcia mixes 4 cups of red paint
or for 1 cup of red paint garcia mixes 1/4 cup of yellow paint to the mixture.
Because 1:4=1:1/4
Now in a shade of orange paints there are 4 cups of red paint and 1 cups of yellow paint thus total cups of paint=5
Now 6 cups of red paint cost $42
Thus 1 cup of red paint is equal to 42/6=$7
Thus cost of each red paint is equal to $7
Hence, The unit price for a cup of red paint is equal to $7
