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

My answer is 1170 but the way I figured out the problem was by listing numbers 1-30. the problem state that the 1st row had 10, 2nd row had 12, and 3rd row had 14 and so forth. So I basically did the same method till I got to 30 and then add up all the numbers which gave me the answer of 1170.

Step-by-step explanation:

Answer:

1170

Step-by-step explanation:

hey there,

(the other person just calculated each number themselves then added them up which i guess is okay but not in the long term for when you're taking a test for example or your teacher asks you this kind of question so it's better to memorize a formula.)

< There are two types of sequences: arithmetic and geometric. So also two formulas for finding sums of each. This situation is an arithmetic sequence.

Formula for the sum of an arithmetic sequence: [tex]S_n=\frac{n}{2} (a_1+a_n)[/tex]

We know there are 30 total rows so n = 30. a1 is the very first term of a sequence so this is 10 in this situation. Before we fill in the formula, we should find what an is equal to.

For this, we will use the basic formula you learned previously: [tex]a_n=dn+c[/tex]

d (the common difference) = a2-a1 = 12-10=2

c (the common ratio) = a1-d = 10-2 = 8

an = dn + c = 2(30) + 8 = 68

Now that we have found what a_n is equal to, we can plug everything into the sum equation.

[tex]S_n = \frac{30}{2} (10+68)=1170[/tex]

So 1170 is your final answer. >

Answer:

y = 3x

2y + 2x = 85

x = 10 5/8 y = 31 5/8

Step-by-step explanation:

Let’s say that y = length and x = width. We know that the length is 3 times the width (y = 3x) and the perimeter of the rectangle is 85 (2y + 2x = 85). To solve the system of equations, substitute y = 3x into the other equation. This results in the equation 2(3x) + 2x = 85. We now simplify the equation. 6x + 2x = 85 8x = 85 x = 10 5/8.

Now that we know x, we can substitute it into either equation to solve for y. y = 3(10 5/8) y = 31 5/8

The  system of equation which represent the given situation is 85 = 8x.

And the length and width of the rectangle is 36.86 and 10.62unit respectively.

Perimeter is the distance around the edge of a shape.

[tex]P = 2(l+w)[/tex]

where,

P is the perimeter of the rectangle

l is the length of the rectangle

w is the width of the rectangle.

According to the given question here:

We have,

The perimeter of the rectangle is 85 unit.

Let the width of the rectangle be x unit.

Then, the length of the rectangle be 3x.

Therefore, the equation which represent the situation is given by

85 = 2(x + 3x)

⇒85 = 2(4x)

⇒ 85 =8x

⇒ x = 85/8 = 10.62unit

⇒ 3x = 10.62 × 3 = 31.86 unit.

Hence, the length of the given rectangle is 31.86 unit and width is 10.62 unit .

Answer:

$1720 total liabilities

Step-by-step explanation:

The total liabilites are $1,720.

Liability usually means that you are responsible for something, and it can also mean that you owe someone money or services.

Now given that,

Car worth = $3,200

Loan amount = $1,400

Owe on credit card = $320

Now since liability is the money owe by someone so in the present condition.

Total liabilities = Loan amount + Owe on credit card

⇒ Total liabilities = $1,400 + $320

⇒ Total liabilities = $1,720

which is the required total liabilities.

Thus, the total liabilites are $1,720.

Answer: (1/3,-7); x=1/3; translated to the right 1/3 unit and down 7 units

Step-by-step explanation:

The parent function is:

g(x) = IxI

And we have:

f(x) = I6x - 2I - 7

We canr rewrite f to get:

f(x) = 6*Ix - 1/3I - 7

Then, now let's define some transformations:

If we start with g(x), a translation of N units to the right is:

f(x) = g(x - N)

if we start with g(x), a translation of N units up is:

f(x) = g(x) + N

A translation down would be:

f(x) = g(x) - N

And a vertical dilation of scale factor A is written as:

f(x) = A*g(x)

Then in this case we have:

A translation to the right of 1/3 units.

A dilation of scale factor 6.

A translation down of 7 units.

And the axis of symmetry will be when the absolute value part is equal to zero, or when

6*Ix - 1/3I = 0

And that is when x = 1/3.

Then the correct option is:

(1/3,-7); x=1/3; translated to the right 1/3 unit and down 7 units

Answer:

2201.8348 ; 3 ; x / (1 + 0.01)

Step-by-step explanation:

1)

Final amount (A) = 2400 ; rate (r) = 6% = 0.06, time, t = 1.5 years

Sum = principal = p

Using the relation :

A = p(1 + rt)

2400 = p(1 + 0.06(1.5))

2400 = p(1 + 0.09)

2400 = p(1.09)

p = 2400 / 1.09

p = 2201.8348

2.)

12000 amount to 15600 at 10% simple interest

A = p(1 + rt)

15600 = 12000(1 + 0.1t)

15600 = 12000 + 1200t

15600 - 12000 = 1200t

3600 = 1200t

t = 3600 / 1200

t = 3 years

3.)

A = p(1 + rt)

x = p(1 + x/100 * 1/x)

x = p(1 + x /100x)

x = p(1 + 1 / 100)

x = p(1 + 0.01)

x = p(1.01)

x / 1.01 = p

x / (1 + 0.01)

2201.8348 ; 3 ; x / (1 + 0.01)
