Answer:

y = 1/20 x + 5

Step-by-step explanation:

Let the height of the sand dune after x years be represented by the equation

y = mx+c where;

m is the rate at which the hills is eroding

c is the height of the dunes above the sea

If The hill is eroding at a rate of 1 foot per 20 years,then the rate of eroding per year will be;

1foot = 20years

m = 1year

Cross multiply

20m = 1

m = 1/20 foot/yr...

c = 5foot

Substitute into the formula:

y = 1/20 x + 5

Hence the equation that represent the situation is y = 1/20 x + 5

Step-by-step explanation:

The value of 42−{(7+14)÷7}×4 will be 30.

A mixture of variables, numbers, addition, subtraction, multiplication, and division are called expressions.

An expression is a mathematical proof of the equality of two mathematical expressions.

A statement expressing the equality of two mathematical expressions is known as an equation.

Given,

⇒ 42−{(7+14)÷7}×4

⇒ 42 - { (21)÷7}×4

⇒ 42 - 3×4

⇒ 42 - 12

⇒ 30

Hence "The value of 42−{(7+14)÷7}×4 will be 30".

Answer:

109°

Step-by-step explanation:

To figure this problem out, we should start with the rule that a pentagon's angles add up to 540°. The angles in the given pentagon are 121°, 102°, 108° and 100°. To find x, we need to make sure all 5 angles add up to 540.

121°+ 102°+108° +100°+x=540°

If you add those four given angles, you get 431°.

540° - 431° = 109°

the relationship is transitive

Answer:

I refute the claim that Mexico incited the war. It was rather the U.S under President James Polka that sent troops to occupy Texas, a territory that the Mexicans believed to be theirs.

Step-by-step explanation:

The Velasco treaty signed in 1836 by a war prisoner of Mexican origin, General Antonio Lopex de Santa Anna was not approved by the Mexican government, but the United States capitalized on it to say that the republic of Texas belonged to them. President James Polka used both peaceful and aggressive means to recover that territory. His peace negotiations were rejected by Mexico and despite that, he sent troops to occupy the territory.

They also occupied other territories of Mexico like Santa Fe de Nuevo Mexico. The Mexicans saw this as provocative and sent their soldiers to Texas who ended up killing 11 American soldiers. This resulted in the war that was fought between 1846 to 1848.

Answer:

5p + 4c = 20

Step-by-step explanation:

lets have p stand for the number of popcorn we buy and c stand for the number of candy we buy

you can only spend $20, so we know we need to set our equation equal to $20

now we take the price of of popcorn and multiply it p, the number of popcorn we buy. and we can do the same thing with candy.

so we end up with 5p + 4c = 20

Answer:

Only table C shows proportional relationship

Step by Step Explanation:

Given

Tables A, B an C

Required

Which table shows proportional relationship?

In table A .

x = 2 and y = 20

k = 20/2

k = 10

Also, x = 12, y = 132

k =. 132/12.

k = 11

Both values of k are not equal.

Hence, the table is not proportional

In table B

x = 5 and y = 20

k = 20/5

k = 4

Also, x = 7, y = 30

k =. 30/7

k = 4.29

Both values of k are not equal.

Hence, the table is not proportional

In table C

x = 9 and y = 90

k = 90/9

k = 10

Also, x = 14, y = 140

k =. 140/14

k = 10

Also, x = 24, y = 240

k =. 240/24

k = 10

All values of k are equal.

Hence, the table is proportional

Answer:

a) The difference of a number and six is no less than 15

x - 6 ≥ 15

b) 25 plus a number is at least 13

25 + x ≥ 13

c) g decreased by 25 is at most five

g - 25 ≤ 5

Step-by-step explanation:

a) The difference of a number and six is no less than 15

Let the number be represented by x

We difference is involved in a mathematics question, it requires the application of Subtraction operation, hence:

x - 6 ≥ 15

b) 25 plus a number is at least 13

Let the unknown number be represented by x

When at least is used in Mathematics, is means greater than or equal to a particular value,

Hence,

25 + x ≥ 13

c) g decreased by 25 is at most five

At most means less than or equal to a particular value, hence:

g - 25 ≤ 5

it should be A. 3/4  

Answer:

The probability that a randomly selected call is for a car that won't start because of dead battery or because of no gas is 0.96

Step-by-step explanation:

The percentage of calls for emergency due to dead battery = 90%

The percentage of calls for emergency due to no gas = 10%

The percentage of calls for emergency due to dead battery and no gas  = 4%

Therefore;

The probability that a call for a car that won't start because of dead battery, P(B) = [tex]\left | B \right |[/tex] = 0.9

The probability that a call for a car that won't start because of no gas, P(N) = [tex]\left | N \right |[/tex] = 0.1

The probability that a call for a car that won't start because of dead battery and no gas, P(B∩N) = [tex]\left | B \cap N \right |[/tex] = 0.04

Therefore, the probability that a randomly selected call is for a car that won't start because of dead battery or because of no gas is given as follows;

[tex]\left | B \cup N \right | = \left | B \right | + \left | N \right | - \left | B\cap N \right |[/tex]

Where;

Therefore, we have;

[tex]\left | B \cup N \right |[/tex] = The probability that a randomly selected call is for a car that won't start because of dead battery or because of no gas

Substituting gives;

[tex]\left | B \cup N \right |[/tex] = 0.9 + 0.1 - 0.04 = 0.96

∴ The probability that a randomly selected call is for a car that won't start because of dead battery or because of no gas = 0.96.

Answer: (7, 0)

Step-by-step explanation:

We have the system of equations:

9*x - y = 63

x = y + 7

We can see that the "x" is isolated in the second equation, then we can replace it in the first equation to get:

9*x - y = 63

9*(y + 7) - y = 63

Now we have an equation that only depends on one variable, so we can solve it:

9*y + 63 - y = 63

8*y + 63 = 63

8*y = 63 - 63 = 0

y = 0/8 = 0.

Now we know the value of y, we can replace this in one of the initial equations to find the value of x, i will replace this in the second equation:

x = y + 7 = 0 + 7 = 7

Then the point that is a solution for the system of equations is (7, 0)
