The formula for the volume of a rectangular prism is V = lwh. What is the formula when solved for w?
Answer:
w=V/Ih
Step-by-step explanation:
The formula for the volume of a rectangular prism is given as V = lwh.
✓ we are required to solve for "w" and this can be done by making "w" subject of the formula.
w=V/Ih
Hence, formula for " w" is w=V/Ih

Please do elimination method 2x-9y=-36
-14x+18y=-18
Answer:
The solution to the system of equations will be:
[tex]x=9,\:y=6[/tex]
Step-by-step explanation:
Given the system of equations
[tex]\begin{bmatrix}2x-9y=-36\\ -14x+18y=-18\end{bmatrix}[/tex]
Multiply 2x-9y=-36 by 7
[tex]14x-63y=-252[/tex]
so the system of equations becomes
[tex]\begin{bmatrix}14x-63y=-252\\ -14x+18y=-18\end{bmatrix}[/tex]
Adding both equations
[tex]-14x+18y=-18[/tex]
[tex]+[/tex]
[tex]\underline{14x-63y=-252}[/tex]
[tex]-45y=-270[/tex]
solve -45y = -270 for y
[tex]-45y=-270[/tex]
divide both sides by -45
[tex]\frac{-45y}{-45}=\frac{-270}{-45}[/tex]
Simplify
[tex]y=6[/tex]
For 14x-63y = -270 plug in y = 6
[tex]14x-63\cdot \:6=-252[/tex]
[tex]14x-378=-252[/tex]
Add 378 to both sides
[tex]14x-378+378=-252+378[/tex]
Simplify
[tex]14x=126[/tex]
Divide both sides by 14
[tex]\frac{14x}{14}=\frac{126}{14}[/tex]
Simplify
[tex]x=9[/tex]
Therefore, the solution to the system of equations will be:
[tex]x=9,\:y=6[/tex]
Sheleah and her family are planning a trip from Los Angeles, California to Melbourne, Australia. While booking her family's plane tickets, she notices on the itinerary that the airline is offering a sixteen hour straight flight from Los Angeles to Melbourne on a Boeing 747-8 Intercontinental Jet. In an effort to learn more about the capabilities of the Jet, Sheleah does a little research and stumbles upon the following graph and facts about the Jet's gasoline consumption.
GRAPH IN SCREENSHOT
The Boeing 747-8 Intercontinental Jet can carry approximately 422,000 gallons of gasoline, making it possible for the jet to travel 14,430 kilometers before needing to refuel.
Using the graph, approximate the Jet's average gas consumption, in gallons per hour, during the sixteen hour flight from Los Angeles, California to Melbourne, Australia. In your final answer, include all of your calculations.
26375
On the graph, it tells you how much fuel is left after 2 hours of the journey.
If we take 422,000 and subtract 369,250 from it we get 52,750. However, this is how much gas is used in 2 hours, so to find one hour we need to divide by 2, getting us 26,375.
Therefore, the Jet uses 26,375 gallons per hour during the 16 hour trip from Los Angeles, CA to Melbourne, Australia.
Find the 16th term of the arithmetic sequence whose common difference is d=6 and whose first term is a 1=3
Answer:
93
Step-by-step explanation:
This question is on Arithmetic sequence, and we can find the 16th term using the Arithmetic sequence formula below;
aₙ= a₁ + (n-1)d
Where n= nth term in that particular sequence.
n₁= first term in the particular sequence.
d= common sequence between the terms.
Given:
d=6
a₁ =3.
Using the formula above,
a₁₆= 3 + (16-1)6
= 3+(15)6
=3+90
=93
Hence, the the 16th term of the arithmetic sequence is 93

Carmen is playing draw and compare decimals with her partner. Carmen drew 4, 7, 6, 0, and 2 and has to use three of the cards to make a decimal less than 1. If they are playing for "more" what decimal should Carmen make? If they are playing for "less" what decimal should Carmen make?
Answer:
Less = 0.24
More = 0.76
Step-by-step explanation:
Given that:
Numbers drawn by Carmen :
4, 7, 6, 0, and 2
To make a decimal less than 1 from the numbers drawn:
First digit would be always be 0 since we aren't considering negative numbers
If they are playing for less; then the least 2 digits will be used in ascending order after the decimal point as;
2, 4
0.24
If they are playing for more; then the highest 2 digits will be used in descending order after the decimal point as;
7, 6
0.76

7/3 x 9/14
and simplified
Answer:
3/2
Step-by-step explanation:
As, 9 is a factor of three so, 9÷3 = 3
So now it's like this: 7/1 x 3/14
Now here 14 is also a factor of 7 so 7 x 2 = 14
So we will cancel it
So, now it's like this 1/1 x 3/2
So finally each an every number that is multipled by 1 is the same so the finally product = 3/2
Or u can just multiply and then divide
7/3 x 9/14 = 63/42
Now u can check both are divisible by 7
So now we will divide by seven so now its
9/6
Here also they are divisible by 3
Divide both numerator and denominator
And u will get 9÷ 3 = 3
And 6÷3 = 2
So, = 3/2
Chose the easier for u!
Hope it helps!

Answer:
56
Step-by-step explanation:
The angle sum theorem *I think* is that for an n-sided shape, the total sum of its angles is 180(n-2).
The sum of a triangles' angles is 180 degrees.
Therefore 4v-44 = 180.
v - 11 = 45
v = 56 degrees
Note: always check if the answer makes sense
Answer:

Step-by-step explanation:
Evaluate y = -4(5)* for x = 2
The value of the function at x = 2 is -100
Exponential equationThey are written in the form y = ab^x
Given the exponential function y = -4(5)^x
IF the value of x is 2, hence the expression becomes:
y = -4(5)^2
y = -4(25)
y = -100
Hence the value of the function at x = 2 is -100
