Answer:
Step-by-step explanation:
I think it's the first last one because proportional means it increases by the same each time so the last one fits in that category
Answer:
Number 1 is proportional, 2 is non proportional, 3 non proportional, 4 non proportional.
Step-by-step explanation:
You divide . 4÷1=4 , 8÷2=4, 12÷3=4, the unit rate MUST be the same !!!! And if there's 0 0, that doesn't count so like if your other 2 have the same unit rate it would still be proportional.
help pleaseeeeeeeeeeeeeeeeeeeee

Answer:
2/11
Step-by-step explanation:
They definitley aren't equal, and 2/11 is closer to 0 than 4/5, so therefore it is less.

One leg of a right triangle is 12, and the hypotenuse is 20.
The length of the other leg is ___
Answer:
i believe it is 16.
hope this helped :)
Answer:
The answer is 16.
Step-by-step explanation:
To solve you need to use Pythagorean Theorem. a^2 + b^2 = c^2 .
12^2 + b^2 = 20^2
144 + b^2 = 400
400 - 144 = 256
b^2 = 256
Next we need to take away the power of 2.
√256 = √b^2
√16 x 16 = √b * b
b = 16

x 0 5 10 15 20
y 10 6.5 23 29.5 36
A. y = 1.3x + 10
B. y = x + 10
C. y = 3.3x + 10
D. y = 1.3x
Answer:
A. y = 1.3x + 10
Step-by-step explanation:
[tex]f(x) = 1 .3x + 10 \\ f(0) =1.3(0) + 10 = 10 \\ f(5) =1.3(5) + 10 = 16.5 \\ f(10) =1.3(10) + 10 = 23 \\ f(15) =1.3(15) + 10 = 29.5 \\ f(20) =1.3(20) + 10 = 36[/tex]

Sally can paint a room in 9 hours while it takes Steve 3 hours to paint the same room. How long would it take them to paint the room if they worked together?
Answer:
2 1/4 hours
Step-by-step explanation:
Okay, so- The first thing I did was see how much they got done per hour. Like this:
Sally ⇒
3 hours = 1 room
1 hour = 1/3 of the room
Steve ⇒
9 hours = 1 room
1 hour = 1/9 of the room
Sally + Steve ⇒
1 hour = 1/3 + 1/9 = 3/9 + 1/9 = 4/9
So, they get 4/9 of a room done in 1 hour.
Number of hours needed ⇒
1 ÷ 4/9 = 2 1/4
Answer: They need 2 1/4 hours to paint the room.
The US consumers in average of 5.15 million metric tons of banana per year. There are 319 million people in the US and there are 1000 kg in one metric ton. Round answer except last one to three significant digits. How many kilogram of bananas are consumed per person per year.
Answer:
bananas consumed per person per year are 4.42 × [tex]10^{-2}[/tex]
Step-by-step explanation:
given data
consumers in average = 5.15 million metric tons
population = 319 million
solution
we get here bananas are consumed per person per year that is express as
bananas consumed = total banana consumed ÷ ( total population × 365 ) .................1
put here value and we get
bananas consumed = [tex]\frac{5.15 \times 1000}{319 \times 365}[/tex]
so, bananas consumed per person per year are 0.044231 kg = 4.42 × [tex]10^{-2}[/tex]
a. 4.0
b. 16.0
c. 12.5
d. 11.7
Answer:
D
Step-by-step explanation:
to find the answer you do the square root of (x2-x1)^2+(y2-y1)^2.
So you just plug it in and get the equation of
the square root of (-4-2)^2+(-8-2)^2 which equals 11.66190379
then you round to the tenths which then comes out to 11.7
Answer:
D. 11.7
Step-by-step explanation:
= √(−4−2)^2 + (−8−2)^2
= √(-6)^2 + (−10)^2
= √36 + 100
= √136
= 11.66 which rounds to 11.7

Find the nth term for the
following sequences:
Q2)3, 9, 15, 21
Answer:
[tex]a_{n}[/tex] = 6n - 3
Step-by-step explanation:
There is a common difference d between consecutive terms, that is
d = 9 - 3 = 15 - 9 = 21 - 15 = 6
This indicates the sequence is arithmetic with n th term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 3 and d = 6, then
[tex]a_{n}[/tex] = 3 + 6(n - 1) = 3 + 6n - 6 = 6n - 3

Answer:
Perpendicular
Step-by-step explanation:
Answer:
Perpendicular
Step-by-step explanation:
The lines shown are intersecting meaning they cannot be parallel as parallel lines never intersect. Moreover, the square in the corner means these lines form a right angle. Lines that intersect and form right angles are perpendicular.

Use the linear combination method to solve the system of equations.
–2.1x + 4y = 5.3
2.1x – 5.5y = –0.2
What is the solution to the system?
(, )
Answer:
The solution to the system of equations is:
[tex]x = -9[/tex], [tex]y=-3.4[/tex]
Step-by-step explanation:
Given the system of equations
-2.1x + 4y = 5.3
2.1x - 5.5y = -0.2
Solving the system of equations using the linear combination method
[tex]\begin{bmatrix}-2.1x+4y=5.3\\ 2.1x-5.5y=-0.2\end{bmatrix}[/tex]
adding the equations
[tex]2.1x-5.5y=-0.2[/tex]
[tex]+[/tex]
[tex]\underline{-2.1x+4y=5.3}[/tex]
[tex]-1.5y=5.1[/tex]
solving -1.5y = 5.1 for y
[tex]-1.5y=5.1[/tex]
Divide both sides by -1.5
[tex]\frac{-1.5y}{-1.5}=\frac{5.1}{-1.5}[/tex]
[tex]y=-3.4[/tex]
substitute y = -3.4 in 2.1x - 5.5y = -0.2
2.1x - 5.5y = -0.2
2.1x - 5.5(-3.4) = -0.2
2.1x + 18.7 = -0.2
2.1x = -0.2-18.7
2.1x = -18.9
Divide both sides by 2.1
[tex]\:\frac{2.1x}{2.1x}\:\:=\:\:\frac{-18.9}{2.1}[/tex]
[tex]x = -9[/tex]
Therefore, the solution to the system of equations is:
[tex]x = -9[/tex], [tex]y=-3.4[/tex]
Select the equation of a straight line that is perpendicular to the line y = 3x-2
