A number line going from negative 4000 to positive 4000 in increments of 1000. Which point represents the change of elevation in feet on the hike from the summit to Carter Notch Hut? –4000 –3000 3000 4000

Answer:

she started with 50 marbles

Step-by-step explanation:

The total is 100 than you just subtract 20 and 30 becasue that is what is added later on. After you subtract 20 and 30 from 100 you will get 50. Therefore Sara had started out with 50 marbles.

Hope that helps :)

Answer: 50 marbles

Step-by-step explanation: Working backwards we ended with 100 marbles so subtracting the 30 marble we're told she bought at the store and subtracting an additional 20 marbles she received for her birthday leaves her with 50 marbles or mathematically 100-30-20=x where x=50

Answer:

m = x+y-z

Step-by-step explanation:

Given the expression.

(a^x a ^y) ÷ a^z = a^m

We are to express m in terms of x, y and z.

Using the multiplicative law of indices, the expression becomes:

a^{x+y} ÷ a^z = a^m

Applying the division rule in indices

a^{x+y} ÷ a^z = a^{x+y-z}

The equation becomes

a^{x+y-z} = a^m

Cancel out the base and equate the powers as shown:

x+y-z = m

Hence the expression of m in terms of x, y and z is m = x+y-z

Answer:

$52

Step-by-step explanation:

To find an original price you must find how much of a percent was left before the discount.

100% - 15% = 85%

You then take this percentage a DIVIDE it by the new price.

$44.20/85% = $52 is the original price of the jeans.

Answer:

A: product of powers

B: quotient of powers

E: negative exponent

Step-by-step explanation:

Let's evaluate to see which several rules we would be applying in each step

[tex] \frac{((-8)^4)^{-5}}{(-8)^6} [/tex]

[tex] \frac{((-8)^{4*-5}}{(-8)^6} [/tex] (power of a power)

[tex] \frac{(-8)^{-20}}{(-8)^6} [/tex]

[tex] (-8)^{-20 - 6} [/tex] (quotient of powers)

[tex] (-8)^{-26} [/tex]

[tex] \frac{1}{(-8)^{26}} [/tex] (negative exponent)

Thus, the rules of exponents we have applied to far are:

A: product of powers

B: quotient of powers

E: negative exponent

Answer:

product of powers

quotient of powers

negative exponent

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)

Answer:

2201.8348 ; 3 ; x / (1 + 0.01)

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

Givens

WX = 4 + 3 = 7

ZY = 7 + 6 = 13

Height = 4 + 6 = 10

Formula

Area = (WX + ZY ) * height /2

Solution

Area = (7 +13)*10 / 2

Area = 20*10/2

Area = 200/2

Area = 100

Step-by-step explanation:

Answer:

So, we know that a square has all sides equal. We need to multiply 15 by 15 to get the area of the square.

A = L x W

A = 15 x 15

   = 225cm squared

Therefore, your answer is 225cm squared.

Answer:

$16.62 each

Step-by-step explanation:

First, find 20% of the bill to figure out how much the tip is worth:

20% over 100% = $x over $55.40 ---> 20 * 55.4 / 100 = 11.08

Now that we know the tip is $11.08, next add it on to the bill:

$11.08 + $55.40 = $66.48

Now divide this by 4 to split the bill evenly between the 4 friends:

$66.48 / 4 = $16.62

a)11cm

b)25cm

you do 44cm divide by 4 which equals to 11

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/x times 1/y squared

Step-by-step explanation:

Answer:

Option C

Step-by-step explanation:

Given polynomial is,

x² - 3x - 18 = x² - 6x + 3x - 18

                 = x(x - 6) + 3(x - 6)

                 = (x + 3)(x - 6)

We can rewrite the polynomial in factored form as,

x² - 3x - 18 = (x - 6)(x + 3)

Therefore, (x - 6) will be one of the factors of the given polynomial.

Option (C) is the answer.

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: (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
