Answer:
40.32 cm²
Step-by-step explanation:
The area of the small rectangle = 7 × 4 = 28 cm²
Given the ratio of the sides of similar rectangles = a : b , then
the ratio of the areas = a² : b²
Here ratio of sides = 4 : 4.8 = 1 : 1.2
ratio of areas = 1² : 1.2² = 1 : 1.44
Let x be the area of the larger rectangle then by proportion
[tex]\frac{1}{28}[/tex] = [tex]\frac{1.44}{x}[/tex] ( cross- multiply )
x = 40.32
Area of larger rectangle is 40.32 cm²

82+(9x+2)+(7x)=180
82+2+16x=180
16x+84=180
16x=96
X=6
If we plug in X to angle(9x+2) and angle (7x) we will get 56 and 42. We can get angle 2 by subtracting 180-42 which is 138
FINAL ANSWER: 138 degrees

Evaluate y = -4(5)* for x = 2
Answers
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

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.
Answers
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.

Please do elimination method 2x-9y=-36
-14x+18y=-18
Answers
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]

Answers
Answer:
80 pages
Step-by-step explanation:
Point slope Equation is :
y = mx + c
In the above question
y = 310 pages
x = number of days = 10 days
m= 23 pages per day
c = ?? Unknown
c = y - mx
c = 310 - 23 × 10
c = 310 - 230
c = 80 pages
She will still have 80 pages left to read after 10 days
