Answer:
1.5
Step-by-step explanation:
Answer:
1 1/2
Step-by-step explanation:
-2 1/4 = [tex]-\frac{(2*4)+1}{4}= -\frac{9}{4}[/tex]
-1 1/2 = [tex]-\frac{(1*2)+1}{2}=-\frac{3}{2}[/tex]
-2 1/4 ÷ -1 1/2 = [tex]-\frac{9}{4} * -\frac{2}{3}[/tex]
= [tex]\frac{3}{2}[/tex]
= 1 1/2

A blueprint of an apartment is shown below. What is the actual length of the longest wall in the living room in feet? 0.5 inch : 6 feet Living Room Bedroom Bath 1.5 in.
Answer:
36 feet long.
Step-by-step explanation:
If the longest wall in the living room is referring to the side that I have drawn over in white and red in the attached image, or if it is the leftmost wall, then that wall is 36 feet long. For every half inch, it is 6 feet, so because there are 6 'half inches' in 3, you multiply 6 feet by the 6 half inches there are, and get 36. There are simpler ways to solve it but I can't take a picture of my work, so I hope this helps. Good luck.
The actual length of the longest wall in the living room is 36 feet.
The blueprint is a scale drawing of the apartment. A scale drawing is a smaller diagram of a large image. A scale drawing is reduced by constant dimensions.
Looking at the given image, the longest wall is 3 inches.
The length of the longest wall in the apartment : (3 in x 6) / 0.5
=18 / 0.5
= 36 feet

The scatter plot shows a correlation between the number of participants and the year of
the snowboarding competition.
The line of regression models that correlation.
Enter a number to complete each statement.
Answers:
In 2003, there were 32 ...
The model predicts ... 40 ...
... 8 below what the model predicted
In 2003, there were 32 ...
-> We find the x-axis of 2003 and look up until we hit the line, then we find the y-coordinate for that point
-> 32
The model predicts ... 40 ...
-> The green 8 with an arrow shows the prediction
-> 40 - 8 = 32
-> 40
... 8 below what the model predicted
-> The green 8 shows the difference in the prediction and the actual participation
-> 8

Answer:
d. V = π(x^3 + 90x^2 + 2,400x + 20,000)
Step-by-step explanation:
volume of cylinder = πr^2h
We have r = x + 20; h = x + 50
V = π(x + 20)^2(x + 50)
V = π(x^2 + 40x + 400)(x + 50)
V = π(x^3 + 50x^2 + 40x^2 + 2000x + 400x + 20,000)
V = π(x^3 + 90x^2 + 2,400x + 20,000)
If a – 2 = -12, then a = ______.
Answer:
a= -10
Step-by-step explanation:
To do this you would need to isolate a, or make a stand alone on its side of the equation
a-2=-12 Original equation
a-2+2 = -12+2 Isolating the variable(adding the 2 will cancel the -2 on the left side of the equation)
a= -12+2 Simplification
a= -10 The answer!!!
I hope this helps!!!

Ammar hikes 2 3/4 miles of nature trail in 1 hour and 15 minutes. 4
How many miles of trail does Ammar hike per hour?
Answer:
.42 mph
Step-by-step explanation:
The problem tells us theres 2.75/1.15 miles/hour. And we want to know x/1 miles/hour. To do this you cross-multiply using whats been referee to as the butterfly method. So take 2.75*x=1.15*1. Then you simplify and get 2.75x=1.15. To get x along you must divide which leaves you with. X=.4182(rounded). So you can go .42 miles per hour.

HELPPPPPPPPPPP!!!!!!!!! Oh
Answer:
We conclude that:
[tex]3\cdot \:2\begin{pmatrix}-2&3&0\\ -4&2&6\\ 6&-5&6\end{pmatrix}=\begin{pmatrix}-12&18&0\\ -24&12&36\\ 36&-30&36\end{pmatrix}[/tex]
Hence, option B is correct.
Step-by-step explanation:
Given the expression
[tex]3\times 2\begin{pmatrix}-2&3&0\\ \:-4&2&6\\ \:6&-5&6\end{pmatrix}[/tex]
solving
[tex]3\times 2\begin{pmatrix}-2&3&0\\ \:-4&2&6\\ \:6&-5&6\end{pmatrix}[/tex]
Scalar Multiplication: Multiply each of the matrix elements by a scalar
[tex]=\begin{pmatrix}3\cdot \:2\left(-2\right)&3\cdot \:2\cdot \:3&3\cdot \:2\cdot \:0\\ 3\cdot \:2\left(-4\right)&3\cdot \:2\cdot \:2&3\cdot \:2\cdot \:6\\ 3\cdot \:2\cdot \:6&3\cdot \:2\left(-5\right)&3\cdot \:2\cdot \:6\end{pmatrix}[/tex]
Simplify each element
[tex]=\begin{pmatrix}-12&18&0\\ -24&12&36\\ 36&-30&36\end{pmatrix}[/tex]
Therefore, we conclude that:
[tex]3\cdot \:2\begin{pmatrix}-2&3&0\\ -4&2&6\\ 6&-5&6\end{pmatrix}=\begin{pmatrix}-12&18&0\\ -24&12&36\\ 36&-30&36\end{pmatrix}[/tex]
Hence, option B is correct.
