Answer:

Ice forces the cracks to become larger and larger, eroding bits of stone in the process. During brief, heavy rains, water rushes down the cracks, eroding even more rocks and stone. As more rocks crumble and fall, the canyon grows wider at the top than at the bottom.

C) 718.3 cubic yards

Step-by-step explanation:

I hope this helps :)

Answer:

228.6π cubic yards

Step-by-step explanation:

Volume of a cone formula: V = 1/3hπr²

h = 14

r = 7

Just plug in the values.

1/3(14)π(7)² = 228.6π

-4x = y + 3

y = -4x - 3​ => 4x = -y - 3

-4x = y + 3

4x = -y - 3

----------------

0 = 0 (always true)

All Real Numbers

Answer:

x = x, y = -3 - 4x

Step-by-step explanation:

Subtract y from both sides of the equation.

-4x - y = 3

y = -4x - 3

Add 4x to both sides of the equation.

-4x - y = 3

y + 4x = -3

-4x - y = 3

Reorder the polynomial.

Add the two equations together to eliminate y from the system.

 -4x - y = 3

+ 4x + y = -3

          0 = 0

Since 0 = 0, the equations intersect at an infinite number of points.

Infinite number of solutions.

Solve one of the equations for y.

y = -3 - 4x

The solution is the set of ordered pairs that make y = -3 - 4x true.

Point form: (x, -3 -4x)

Equation Form: x = x, y = -3 - 4x

Answer:

[tex]\boxed{\textsf{ The degree measure is \textbf{ 48}$^{\textbf{o}}$.}}[/tex]

Step-by-step explanation:

Here we are given radian measure which is 4π/15 radians . We know the relationship between Radian and Degree measure as ,

[tex]\qquad\boxed{\boxed{ \sf\pi rad = 180^o }}[/tex]

Put on the respective values ,

=> π rad = 180°

=> 1 rad = 180°/ π

=> 4π/15 rad = 180°/π × 4π/15

Answer:

4.734 * 10^-5 miles

Step-by-step explanation:

Given that:

Distance between House to movie theater = 3 inches

Expressing the distance in miles :

Converting inch to miles

1 inch = 1.578 * 10^-5 miles

3 inches = (3 * 1.578*10^-5)

Answer:

1. x³y² + 4x²y³ + 7y⁴ + x⁴

2. a² + b² + c² + 2ab + 2bc + 3ca

Step-by-step explanation:

1. x³y² + x²y³ + 3y⁴ and x⁴ + 3x²y³ + 4y⁴

= x³y² + x²y³ + 3y⁴ + x⁴ + 3x²y³ + 4y⁴

= x³y² + x²y³ + 3x²y³ + 3y⁴ + 4y⁴ + x⁴

= x³y² + 4x²y³ + 7y⁴ + x⁴

2. a² + 3ab - bc, b² + 3bc - ca and c² + 3ca - ab

= a² + 3ab - bc + (b² + 3bc - ca) + (c² + 3ca - ab)

= a² + 3ab - bc + b² + 3bc - ca + c² + 3ca - ab

= a² + b² + c² + 3ab - ab + 3bc - bc + 3ca - ca

= a² + b² + c² + 2ab + 2bc + 3ca

Answer:

Jeremy's team lost by 1 to get a tied game but his team lost by 2 for the win

Answer:

GH = 13

FG = 20

<F = 78

<G = 102

<H = 78

Step-by-step explanation:

Since there are 5 measures that are missing, we will do each one in a different part.

1.  The side length of GH is 13. Since this is a parallelogram, the opposite side of your original side is congruent, meaning that its the same. So, knowing that the opposite of FI is GH, we can say that GH is 13 units long.

2. We can use the same logic for number 2, when finding FG. Since HI is 20. we can say that since the corresponding side is also congruent to our original length, they are equivalent. Basically meaning they are the same

3. a. For finding F, we will need to use a different method. Since a parallelogram is somewhat like a transversal we can use that to our advantage. (If you don't know what a transversal it, look at part B instead) Since we know that angle I is 102, and both line FG and HI are parallel, the angles are basically adjacent, when switched. So we should see that it would have to be 78. Meaning that F is 78.

3. b. If you don't understand what a transversal is, we can still figure it out. Knowing that the figure is a closed shape, along with knowing that its a parallelogram, we can say that if we were to sum the angles F and I, we would get 180. 180-102=78, so F is 78.

4. Since we can use a transversal or just pure logic to say that angle G and I are equivalent, meaning that G is 102.

5. This one is exceptionally simple, just for the fact that we have answered the previous questions. We have H left, which is not only equivalent to F, but using 3. b. we can say that its would only make sense that H is 78 as well, to sum up that half to 180.

how am i gonna solve the equation if i cant see the actual chart?

Step-by-step explanation:

Step-by-step explanation:

p(x) = 15x-(2000+4x)

profit is going to be the difference between how much money you get from sales less the cost to make the items

the money you make in this case is $15 times the number of cds you sell, we will call the number of cds x

so 15x is the money from sales

the costs you have are 2000 to create the master and then $4 for every cd you create, so your costs will be 2000+4x

so profit is sales minus costs, therefore we get

p(x) = 15x - (2000+4x)

now to find specifically the profit when we create and sell 2800 cds, x = 2800, so we substitute that value in for x

p(2800) = 15(2800) - (2000+4(2800))

= 42000 - (2000+11200)

= 42000 - 13200

= 28800

The profit of selling 2800 additional DVDs is 28800 dollars.

A function can be defined as the outputs for a given set of inputs.

The inputs of a function are known as the independent variable and the outputs of a function are known as the dependent variable.

Given, The profit function is P, and let no. of DVDs sold is x and the profit on each additional disc is,

= $(15 - 4).

= $11.

∴ The profit function p is,

P = 11x - 2000.

So, the profit by selling 2800 additional discs is,

P = 11(2800) - 2000.

P = 30800 - 2000.

P = 28800 dollars.

Answer:

A) v = T/2 - 5

Step-by-step explanation:

T = 10+2v

2v = T-10

v = (T-10)/2 = T/2-5

The equation that describes no. of DVDs that Ingrid can rent is A.              v = (T/2) - 5.

An equation states that terms on both sides of the equality sign are equal.

The monthly membership costs 10 dollars, and The rent for each DVD costs 2 dollars.

No. of DVDs that can be rented is denoted by v based on T.

The equation that describes the total cost of renting DVDs is,

T = 2v + 10.

∴ The equation that describes no. of DVDs that can be rented is

2v = T  - 10.

v = (T/2) - 5.

Answer:

No, you didn't

Step-by-step explanation:

20% of $1200 is:

Since you saved $200 and its less than $240 you didn't reach your goal

Hi there!

No:

200 is only 6 parts of 1200 together which means that it can’t be 20% of 1200.

If it was 20% of 1200, it would then be 240 since 240·5=1200...

What this means:

No, did not reach the goal since 20% of 1,200 is 240 and 200 is only 16.67% of $1,200.

Slope is -15/8

Final answer is -15/8

I hope this helps you!

Have  a nice day! :)

:D

Step-by-step explanation:

Slope is rise over run. This means your y is over your x. Start with subtracting your y values. It doesn't matter which way, just make sure you do the same with the x values. For this, I'll do it 6 - -9. The two negatives cancel out and make a positive, so your y value is 15. Now, do the same to the x values. -9 - -1 is -8. You're left with 15/-8. Since this can't be simplified, this is your final answer. Hope I helped!
