Answer:
The mass of CO2 produced by one liter of fuel is 2,200 gr/lt
Step-by-step explanation:
Proportions
To find the cross-relation between the mass of CO3 produced and the liters of fuel used we must find the unit rate of both relationships given.
We know:
The car uses 5 liters of fuel per 100 Km. The unit rate is 5/100 lt/km
The car produced 110 grams of CO2 for each kilometer traveled. The unit rate is 110 gr/Km
Since the kilometers is the common unit, we find the unit rate of CO2/fuel:
[tex]\displaystyle \frac{\frac{110}{1}}{\frac{5}{100}}=\frac{110}{1}}*\frac{100}{5}}= 110*20 = 2,200[/tex]
The mass of CO2 produced by one liter of fuel is 2,200 gr/lt
PLEASE HURRY Find the midpoints between points C (7, -9) and D (3, 5).
Answer:
(5,-2)
Step-by-step explanation:
Midpoint formula
If we have coordinates (x₁,y₁) and (x₂,y₂), then the midpoint of these coordinates is determined by (x₁ + x₂)/2, (y₁ + y₂)/2. This forms a new coordinate you can call (x₃,y₃). The midpoint calculator will solve this instantaneously if you input the coordinates. Follow the steps above if calculating by hand.
For small numbers, it's easy to calculate the midpoint by hand, but with larger and decimal values, the calculator is the simplest and most convenient way to calculate the midpoint.
Answer:
Midpoint=(5,−2)Step-by-step explanation:
Midpoint formula
m=((x1+x2)/2,(y1+y2)/2
so lets plug in
((7+3)/2,(-9+5)/2)
(10/2),(-4/2)
(5,−2)

1. A term that is a known number without variables. is called?
2. A term that includes a variable. is called?
Answer:
Constants are the terms in the algebraic expression that contain only numbers. That is, they're the terms without variables. We call them constants because their value never changes, since there are no variables in the term that can change its value.
An algebraic expression is one or more algebraic terms in a phrase. It can include variables, constants, and operating symbols, such as plus and minus signs.

Parallelograms s and t are each labeled with a base and a corresponding height
Answer:
Parallelogram S:
b = 7 and h = 6
Parallelogram T:
b = 3 and h = 6
Step-by-step explanation:
The given information is incomplete and is not enough to answer the question. (See attachment for complete question)
Required
Determine the values of b and h for both parallelogram
The question will be answered by observing the features of each parallelogram and recording the required values
For parallelogram S.
The vertical arrow at the left-hand side represents b and the arrow highlights 7 grid boxes.
Hence:
[tex]b = 7[/tex]
The horizontal dotted lines represents h and this line highlights 6 grid boxes.
Hence:
[tex]h = 6[/tex]
For parallelogram T.
The horizontal arrow represents b and the arrow highlights 3 grid boxes.
Hence:
[tex]b = 3[/tex]
The vertical dotted lines represents h and this line highlights 6 grid boxes.
Hence:
[tex]h = 6[/tex]
What is the equation of the line that passes through the point
(5,−7) and has a slope of 0?
Answer:
y = -7
Step-by-step explanation:
It has a slope of zero (it is just a straight,infinite line)
And it passes through the point (5,-7) because it is continuous and infinite
Which equation has no solution?
A. 13y + 2 - 2y = 10y + 3 - y
B. 9(3y + 7) - 2 = 3(-9y + 9)
C. 32.1y + 3.1 + 2.4y - 8.2 = 34.5y - 5.1
D. 5(2.2y + 3.4) = 5(y - 2) + 6y
Answer:
D
Step-by-step explanation:
Option D is the only equation where the y-term gets eliminated upon simplifying
11y + 17 = 5y - 10 + 6y
11y + 17 ≠ 11y - 10

Im not in high school soooo but it is the correct answer
Plz and quick!
I rly rly need this
Step-by-step explanation:
20x² = y - 24
y = 20x² + 24
For y to have the least possible value, x² have to be the least possible, which is 0.
Since -3 <= x <= 2 includes x = 0, this is allowed.
Hence least possible value of y
= 20(0)² + 24 = 24.
Answer:
24
Step-by-step explanation:
-3---> 20(-3)^2=y-24 ----> y=204
-2---> 20(-2)^2=y-24 ----> y=104
-1---> 20(-1)^2=y-24 ----> y=44
0---> 20(0)=y-24 ----> y=24
1---> 20(1)^2=y-24 ----> y=44
2---> 20(2)^2=y-24 ----> y=104

Carlos visita a sus abuelos cada 12 dias y su hermana sofia,cada8 dias.La ultima vez que conincidieron en la visita fue el dia 3 de enero ¿cuando volveran a coincidir? ¿cuantas veces habran visitado a sus abuelos cada uno entre los dos periodos que han coincidido?
Responder:
27 de enero
Horas de visita al abuelo antes de que coincida el horario = 1 vez
Horas de visita a Sofía antes de que coincida el horario = 2 veces
Explicación paso a paso:
Para obtener la hora en la que coincidirá su visita, obtenemos la L. C. M de 12 y 8
Abuelos (cada 12 días)
12:12, 24, 36, 48, 60, ...
Sofia (cada 8 días)
8: 8, 16, 24, 32, 40, ....
El mínimo común múltiplo de 12 y 8 es 24.
De ahí que su encuentro vuelva a coincidir a los 24 días.
3 de enero + 24 días = 27 de enero
Horas de visita al abuelo antes de que coincida el horario = 1 vez
Horas de visita a Sofía antes de que coincida el horario = 2 veces
A 32-ounce jar of a barbecue sauce costs $8.00, while an 8-ounce jar of the same
sauce costs $4.00. How much less does Jennifer pay per ounce by purchasing
the jar that costs less per ounce?
Answer:
Jennifer would save $0.25 per ounce.
Step-by-step explanation:
With the 32-ounce jar, the price per ounce is $0.25 per ounce. With the 8-ounce jar, the price is $0.50 per ounce. Jennifer would do better to buy the 32-ounce jar, as she would save $0.25 per ounce with that choice.

What are different values in a linear equation of a straight line?
The equation y = mx + c is the general equation of any straight line where m is the gradient of the line (how steep the line is) and c is the y-intercept (the point in which the line crosses the y-axis).
y = mx + c is a linear equation and the variables x and y relate to coordinates on the line.
When we input a value for x into the equation y = mx + c, we get a result for y.
This means that x is an independent variable, and y is a dependent variable as it is determined by the value of x.

Answer:
9
Step-by-step explanation:
150/2 = 75
72/8=9
Answer:
v is 9 degrees
Step-by-step explanation:
The 2 angles are supplementary angles
Therefore,
8v + 3 + 105 = 180 (supplementary angles add up to 180 degress/straight line)
8v = 180 - 105 - 3
8v = 75 - 3
8v = 72
v = 72/8
v = 9 degrees

There are 4 different animals at a farm.
There are 19 more cows than Than sheep
19 ducks more than hens
So there are more hens than cows. How many animals are there in all.
Step-by-step explanation:
As per question
Cows - sheep = 19
Ducks - hens = 19.
One more relation between cow and hens should be given or given but data is missing. Necessary information is missing to find total number of animals. This is all one can do as per provided data.
x = - 5
x ^ 2 + y ^ 2 = 25
show work also
Step-by-step explanation:
Since x is equal to -5, you would need to substitute that value for x in the equation x^2 + y^2 = 25. So....
-5^2 + y^2 = 25
(-5)*(-5) + y^2 = 25
25 + y^2 = 25
y^2 +25 - 25 = 25 - 25
y^2 = 0
y = 0
(x, y) = (-5, 0)
To check the answer....
x^2 + y^2 = 25
-5^2 + 0^2 = 25
25 + 0 = 25
25 = 25
The answer should be correct, if not i am extremely sorry
Hope this helps!!!

Solve. Chanasia has 6.25 gallons of paint. She wants to use 2/5 of the paint to paint her living room. How many gallons of paint will Chanasia use?
Answer: 2.5 gallons
Step-by-step explanation:
Given that:
Gallons of paint had = 6.25 gallons
Amount needed to paint room = 2/5 of the paint
Gallons of paint needed :
2/5 of 6.25
(2 * 6.25) / 5 gallons
= 12.5 / 5
= 2.5 gallons
Diego collected x kg of recycling. Lin collected 2/5 more than that. [ Select ] Lin biked x km. Diego biked 3/10 less than that. y = 10/3x Diego read for x minutes. Lin read 4/7 of that. y = 7/4x
I assume you want to mathematically represent the above
Answer and explanation:
If Diego collected x kg of recycling and Lin collected 2/5 more than what Diego collected, then it would be represented mathematically thus:
Diego = x
Lin = x +2/5 of x= x+2/5x
if Lin biked x km and Diego biked 3/10km less than Lin, then we would represent this thus:
Lin=x
Diego= x-3/10 of x= x-3/10x
If Diego reads for x minutes and Lin reads 4/7 of what Diego read, then mathematically we represent this thus:
Diego=x
Lin =4/7 of x = 4/7x

someone help ASAP !! algebra II
Answer:
C
Step-by-step explanation:
Given y = f(x) then y = f(x + a) is a horizontal translation of f(x)
• If a > 0 then a shift to the left of a units
• If a < 0 then a shift to the right of a units
Thus (x - 5)² is a shift to the right of 5 units
Given y = f(x) then y = f(x) + c is a vertical translation of f(x)
• If c > 0 then a shift up of c units
• If c < 0 then a shift down of c units
Thus
y = (x - 5)² + 6
is the graph of y = x² translated 6 units up and 5 units to the right → C
