Answer:
Step-by-step explanation:
There are six sides, in this case they are all equal square faces.
A=6s^2, s, side length is 5.5 so
A=6(5.5)^2
A=6(30.25)
A=181.5 cm^2
which relation is a function of x
Answer:The fourth function
Step-by-step explanation:
You can never have repeating x-values. You can have repeating y-values though. Whenever determining whether something is a function, just look at whether it has repeating x-values or not. If it does, it is not a function. If it doesn't, it is a function.

It is one-half the area of a rectangle with sides 2 units × 3 units.
It is twice the area of a square of side length 3 units.
It is one-half the area of a square of side length 3 units.
Answer: It is one-half the area of a rectangle with sides 2 units × 3 units.
It is twice the area of a square of side length 3 units.
It is one-half the area of a square of side length 3 units.
Step-by-step explanation:
Answer:
It is one-half the area of a rectangle with sides 2 units × 3 units.
Step-by-step explanation:
because the base of the triangle is connected in the "quadrilateral way" the base is one-half the rectangle and the units are 2x3 so therefore that answer is the correct one.
What is the simplified form of the product. (x+6)(x+4) =
Answer:
x² + 10x + 24
Step-by-step explanation:
Use foil to multiply them.
x ( x + 4 ) = x² + 4x
6 ( x + 4) = 6x + 24
Combine like terms: x² + 10x + 24

20 + 60 ÷ 5 + (9 - 4)2
Answer:
42
Step-by-step explanation:
20 + 60 ÷ 5 + (9-4)2
Use PEMDAS to solve this equation, so first solve what is in the parentheses
20 + 60 ÷ 5 + (5)2
Since there are no exponents, next solve the multiplication
20 + 60 ÷ 5 + 10
Next is division
20 + 12 + 10
Finally, addition

Solve the matrix equation for X:
Multiply on the right by the transpose of the matrix on the left side:
[tex]X\begin{bmatrix}1&-1&2\\3&0&1\end{bmatrix}=\begin{bmatrix}-5&-1&0\\5&-2&5\end{bmatrix}[/tex]
[tex]X\begin{bmatrix}1&-1&2\\3&0&1\end{bmatrix}\begin{bmatrix}1&-1&2\\3&0&1\end{bmatrix}^\top=\begin{bmatrix}-5&-1&0\\5&-2&5\end{bmatrix}\begin{bmatrix}1&-1&2\\3&0&1\end{bmatrix}^\top[/tex]
The transpose is just the same matrix with the entries reflected along the main diagonal:
[tex]\begin{bmatrix}1&-1&2\\3&0&1\end{bmatrix}^\top=\begin{bmatrix}1&3\\-1&0\\2&1\end{bmatrix}[/tex]
So
[tex]X\begin{bmatrix}1&-1&2\\3&0&1\end{bmatrix}\begin{bmatrix}1&3\\-1&0\\2&1\end{bmatrix}=\begin{bmatrix}-5&-1&0\\5&-2&5\end{bmatrix}\begin{bmatrix}1&3\\-1&0\\2&1\end{bmatrix}[/tex]
[tex]X\begin{bmatrix}6&5\\5&10\end{bmatrix}=\begin{bmatrix}-4&-15\\17&20\end{bmatrix}[/tex]
Now multiply on the right by the inverse of the matrix on the left side:
[tex]X\begin{bmatrix}6&5\\5&10\end{bmatrix}\begin{bmatrix}6&5\\5&10\end{bmatrix}^{-1}=\begin{bmatrix}-4&-15\\17&20\end{bmatrix}\begin{bmatrix}6&5\\5&10\end{bmatrix}^{-1}[/tex]
[tex]X=\begin{bmatrix}-4&-15\\17&20\end{bmatrix}\begin{bmatrix}6&5\\5&10\end{bmatrix}^{-1}[/tex]
The inverse is
[tex]\begin{bmatrix}6&5\\5&10\end{bmatrix}^{-1}=\frac1{60-25}\begin{bmatrix}10&-5\\-5&6\end{bmatrix}=\begin{bmatrix}2/7&-1/7\\-1/7&6/35\end{bmatrix}[/tex]
So
[tex]X=\begin{bmatrix}-4&-15\\17&20\end{bmatrix}\begin{bmatrix}2/7&-1/7\\-1/7&6/35\end{bmatrix}=\boxed{\begin{bmatrix}1&-2\\2&1\end{bmatrix}}[/tex]

A boat in the ocean knows the nearest lighthouse has a light 220 feet
above the water. They look up at an angle of elevation of 25 degrees to see
the light. How far is the boat from the base of the lighthouse?*
93 feet
199 feet
472 feet
631 feet
Answer:
472 feet
Step-by-step explanation:
The 220 ft is the opposite leg.
The distance from the boat to the base of the lighthouse is the adjacent leg.
tan 25 = 220/x
x = 220/tan 25
x = 472
Answer 472 feet

Two numbers are in the ratio 3: 7. If their sum is 710, find the numbers.
Answer:
the numbers are 213 and 497
Step-by-step explanation:
First, add the digits of the ratio: 3 + 7 = 10
Then, divide the sums: 710/10 = 71
What this does is find the value of each 'unit' - we don't know what 3 is, or 7, but we know that 1 = 71
Since 1 x 3 = 3 and 1 x 7 = 7, by multiplying 71 with 3 and 7 we can find the numbers:
71 x 3 = 213
71 x 7 = 497
u can check this by adding them together: 213 + 497 = 710
hope this helps!

A bakery sells taro, red bean and green tea pues. 65% of the pies are taro pies. 40% of the remaining pies are red bean pies. How many pies are there altogether?
Answer: 1,800 pies in total
Step-by-step explanation:
A key detail missing is that there are 378 green tea pies.
Assuming the total number of pies is x.
65% of this is taro pies. This leaves 35% to be red bean pies and green tea pies.
If 40% of this remaining 35% are red bean pies, that means that 60% are green tea pies.
= 35% * 60%
= 21% of the total are green tea pies
There are 378 green tea pies and this is 21% of the total number of pies.
378 = 0.21 * x
x = 378 / 0.21
= 1,800 pies in total
