Answer:

  100x +150y ≤ 1200

Step-by-step explanation:

The amount Isabel will spend on 5 oz cups is 100x. The amount she will spend on 8 oz cups is 150x. In order to stay within her budget she must have the total be less than or equal to the budget amount:

  100x +150y ≤ 1200

Answer:

A. Fractions 1 and 4

B. Fractions 1, 2, and 3

Step-by-step explanation:

A negative divided by a positive is a negative.

A positive divided by a negative is a negative.

If the negative symbol is in line with the fraction bar, it is still a negative.

Answer:

  y = (5/9)(x -2)(x +6)

Step-by-step explanation:

When a polynomial has a zero (p, 0), it has a factor (x -p).

The given zeros mean the factored form of the equation will be ...

  y = a(x -2)(x +6)

The given point will mean the value of 'a' will satisfy ...

  (x, y) = (3, 5)

  5 = a(3 -2)(3 +6) = 9a

  a = 5/9 . . . . . . . . . . . . . . divide by the coefficient of 'a'

The factored equation is ...

  y = (5/9)(x -2)(x +6)

Answer:

20078/243

Step-by-step explanation:

sn = a1-a1r^n/1-r

sn = a1 * 1-r^n/1-r

s7 = 6 * 1 - (-5/3)^7/1-(-5/3)

s7 = 6 * 10039/729

s7 = 6 * 10039/243*3

s7 = 2 * 10039/243

s7 = 20078/243

It’s D.

Explanation:

First we have to know how many 24’s are there in 672 (because for every 24 cans, $15 would be donated) So you divide 672 divided by 24 which is 28. That means she donated 28 x 15. That ends up being 420 (D).

Hope this helps

Answer:

  b)  10 minutes

Step-by-step explanation:

Ajay's total travel time is the time on the road plus the time stopped.

  A = (300 km)/(60 km/h) + 1 h + 20 min = 6 h + 20 min

Vijay's total travel time is similarly computed:

  V = (300 km)/(50 km/h) + 30 min = 6 h + 30 min

Vijay will arrive 10 minutes after Ajay arrives.

Answer:

-2a³+9a²+45a+6ab²+18b²

Step-by-step explanation:

(a+3)(-2a²+15a+6b²)

Distribute the a:

-2a³+15a²+6ab²

Then distribute the 3:

-6a²+45a+18b²

Now add both of the results together:

-2a³+15a²+6ab²-6a²+45a+18b²

Combine like terms:

-2a³+9a²+45a+6ab²+18b²

Answer:

  (c)  −2a^3+9a^2+45a+6ab^2+18b^2

Step-by-step explanation:

Examination of the answer choices shows us we only need to be concerned with the a^2 term and the b^2 term.

The a^2 term will be the sum of products ...

  3(-2a^2) +a(15a) = (-6 +15)a^2 = +9a^2

The b^2 term will be the product ...

  3(6b^2) = 18b^2

These terms are sufficient to identify choice C as the correct answer choice.

Additional comment

It can often work well to develop the product of polynomials by considering the terms that must contribute to a given product term. For a term containing a^2, the product of polynomial terms can have that degree if and only if it is the product of a constant and an a^2 term, or the product of two a^1 terms. The ways those products can be achieved are shown in the above working.

Answer:

36

Step-by-step explanation:

The integral with the prescribed order of integration would be
[tex]\displaystyle \iiint_D f(x,y,z) \, dV = \int_{-\sqrt5}^{\sqrt5} \int_{x^2}^5 \int_{4-y}^{y-6} f(x,y,z) \, dz \, dy \, dx[/tex]

• z is bounded between two planes, z = 4 - y and z = y - 6. These planes meet in a line with coordinates y = 5 and z = -1. Deciding which plane lies above the other comes down to checking the value of z for some y-coordinate of any point that we know belongs to D. The parabolic face y = x² contains the origin (0, 0, 0), so we know there are points in D with y-coordinate = 0. When y = 0,
z = 4 - y = 4
z = y - 6 = -6
and this tells us that 4 - y is the "upper" plane.

• y is bounded between the parabolic cylinder y = x² and the plane y = 5, which we determined earlier when finding where the two planes intersect. This also tells us that 0 ≤ y ≤ 5 for any point in D.

• x is bounded between -√5 and +√5, since at most y = 5, so that
y = 5 = x²   ⇒   x = ±√5

Answer:

11 you have to put the numbers in order and then if there is an even amount then the middle two numbers you add them and then divide by 2

Answer:

The median is 11

Step-by-step explanation:

1. You have to arrange the numbers from smallest to largest

2, 8, 10, 11, 11, 11, 13, 14, 18, 19

2. If the number of data points is odd, the median is the middle data point in the list. But since this number of data points is even, the median is the average of the two middle data points in the list.

So you would add the two numbers that are in middle, in this case they're both 11

11 + 11 = 22

22 divided by 2 = 11

Answer:

Option 3

Step-by-step explanation:

Option 3 is not a function as there is no regular pattern like the other functions. In mathematics, instructions in a function are constant and cannot be changed meaning that there will always be some kind of pattern with each produced value.

Let's see an example:

[tex]f(x) = 2x + 1[/tex]

For each value of x, each outcome will have gone through the same process. The first 5 values of this function will be 3, 5, 7, 9, 11.

The pattern here is that every outcome is an odd number.

Returning to the question, each option (excluding option 3) has a pattern.

Option 1: Y is always 1 and X is increasing by 1 each time, starting from 0.

Option 2: X is always 0 and Y is increasing by 1 each time, starting from 0.

Option 4: X and Y are increasing by a factor of 2 each time, starting from 0.

But, there is no pattern with option 3.

I hope this helps.

Answer:

y = -3x -1

Step-by-step explanation:

Slope intercept form is y=mx+b or y=mx-b

m is the slope (steepness of the line, think of a steep or level mountain)

b is the y-intercept (the place where the line FIRST meets the y-axis a.k.a. the vertical line down the middle of a graph.)

y= -3x -1

means your line is going downhill, and it crosses the y-axis at -1.

According to the valence number of copper(2+) and the same value for chlorine (1-) copper (II) chloride has the formula of CuCl2

The molar mass of copper is 0,0635 kg/mole and chlorine gas a molar mass of 0,035 kg/mole the compound will have a molar mass of ( 0,0635+2×0,035 )kg/mole=0,099kg/mole and 0,344 moles are equivalent in mass to 0,344×0,135 kg=0,046 kg
