Ms. Ford is buying bundles of virgin hair from She’s Happy Hair that costs $75 per bundle, but $42.50 for shipping. If Ms. Ford spent $567.50 total, how many bundles of virgin hair did she buy?

Answers

Answer: 7 bundles.

Step-by-step explanation:

The cost per bundle is $75.

The cost for shipping is $42.50

She spent $567.50 in total.

The shipping is paid only one time, as all the bundles can be packaged togheter.

Then after paying the shipping, the left spent is:

$567.50 - $42.50 = $525

And each bundle costs $75, then the number of bundles that she bought will be equal to the number of times that we have $75 in $525. This is equal to the quotient between $525 and $75.

N = $525/$75 = 7

She bought 7 bundles

The amount of revenue brought in by states from motor vehicle licenses increased at a relatively constant rate of 499.79 million dollars per year from 1990 to 2000. In 2000, the states brought in 15,099 million dollars in revenue from motor vehicle licenses

Answers

Answer:

a. the approximate revenue from licenses in 1990 was $10,101.10 million.

b. The function is x = 10,101.10 + 499.79y

c. The revenue from licenses in 1999 is $14,599.21 million.

Step-by-step explanation:

The amount of revenue brought in by states from motor vehicle licenses increased at a relatively constant rate of 499.79 million dollars per year from 1990 to 2000. In 2000, the states brought in 15,099 million dollars in revenue from motor vehicle licenses.

a: what was the approximate revenue from licenses in 1990?

b: write an equation that gives the revenue as a function of the number of years since 1990.

c: find the revenue from licenses in 1999.

a: what was the approximate revenue from licenses in 1990?

This can be calculated using the following function:

x = a + by  ............................... (1)

Where;

x = Amount brought in 2000 = $15,099 million

a = Amount brought in 1990 = ?

b = Amount of relative constant rate of increase = $499.79 million

y = Number of years between 1990 and 2000 = 10

Substituting the values into equation (1) and solve for a, we have:

15,099 = a + (499.79 * 10)

a = 15,099 - 4,997.90

a = $10,101.10 million

Therefore, the approximate revenue from licenses in 1990 was $10,101.10 million.

b: write an equation that gives the revenue as a function of the number of years since 1990.

Using equation (1) in part a above, we substitute the values for a and b to obtain an equation that gives the revenue as a function of the number of years since 1990 as follows:

x = 10,101.10 + 499.79y ....................... (2)

c: find the revenue from licenses in 1999.

Since 1999 is 9th year from 1990, we therefore substitute y = 9 in equation (2) as follows:

x = 499.79 + 10,101.10y

x = 10,101.10 + 499.79(9)

x = 10,101.10 + 4,498.11

x = $14,599.21 million

Therefore, the revenue from licenses in 1999 is $14,599.21 million.

A newly planted tree will be secured by wires, each attached to the ground 1.5 meters from the base of the tree. If each wire is 4 meters long, how high up the tree should each wire be attached, to the nearest tenth of a meter?

Answers

Answer:

3.7m

Step-by-step explanation:

The set up will form of right angled triangle with;

the length of the wires (the hypotenuse) = 4m

The base of the tree from the wire (adjacent) = 1.5m

The height of the tree(opposite ) = x

According to pythagoras theorem;

hyp² = opp²+adj²

4² = x²+1.5²

16 = x²+2.25

x² = 16 - 2.25

x² = 13.75

x = √13.75

x = 3.708

Hence the tree is 3.7m high (to the nearest tenth)

4x - 6 = 30 can you solve it

Answers

Answer:

x = 9

Step-by-step explanation:

take -6 to the other side so you add it to 30 = 36

equation is now 4x = 36

divide 4/4 and 36/4

x = 9

the solution to the equation 4x - 6 = 30 is x = 9

To solve the equation 4x - 6 = 30 and find the value of x, we can follow these steps:

1. Begin by isolating the term with the variable on one side of the equation. In this case, we want to isolate the 4x term. Add 6 to both sides of the equation:

  4x - 6 + 6 = 30 + 6

  4x = 36

2. To solve for x, divide both sides of the equation by 4:

  (4x) / 4 = 36 / 4

  x = 9

Therefore, the solution to the equation 4x - 6 = 30 is x = 9. When we substitute x with 9 in the equation, we have 4(9) - 6, which indeed equals 30. Thus, x = 9 satisfies the equation, and it represents the value that makes the equation true.
