Answers

Answer 1

Answer:

46.20

Step-by-step explanation:

First determine how much he earned:

8.8 per hour times 7 hours

8.80 *7 =61.60

Then determine how much he gave his mother

61.60 * 1/4 =15.4

Subtract this from the total amount to determine how much is left

61.60-15.40

46.20

Can anyone help ? I’m bad at math

Answers

Answer:

Step-by-step explanation:

First you need the third angle (C).

<C + 89  + 45 = 180       All triangles = 180 degrees. Combine the left terms.

<C + 134 = 180               Subtract 134 from both sides

<C = 180 - 134

<C = 46

Next, Let BA = x

x/Sin(46) = 15/Sin(89)

x = 15*sin(46) / Sin(89)

Sin(46) = 0.7193

Sin(89) = 0.9998

x = 0.7193 * 15 / 0.9998

x = 10.7911

Note

When you are studying this material, you should note 2 things.

The first is that you are dealing with 2 ratios that are equal to each other.The second is, the side is always opposite the angle in the triangle. The two are connect. Side c = 15. It is opposite the 89o angle.

Find the number of unique permutations of the letters in each word.
5) CORRIDOR
6) NUMBER

Answers

Answer:

Ur Answer is 5 one CORRIDOR

The number of unique permutations of the letters CORRIDOR is 3360

The number of unique permutations of the letters NUMBER is 720

What is Permutation?

A permutation is a mathematical technique that determines the number of possible arrangements in a set when the order of the arrangements matters. Common mathematical problems involve choosing only several items from a set of items in a certain order.

[tex]\frac{n!}{mA!mB!......mZ!}[/tex]

In the given word

CORRIDOR

There are 7 letters in which "O" repeats 2 times and "R" repeats 3 times.

Then n = 7 , A = 2 and B = 3

Put values in above formula

Then,

=  [tex]\frac{7!}{2!3!}[/tex]

= [tex]\frac{7\times6\times5\times4\times3\times2\times1}{2\times3\times2}[/tex]

= 3360

Similarly

NUMBER

There are 6 letters in which no letter repeats

means A = B = .......= Z = 1

Put values in above equation

= [tex]6![/tex]

= 720

Hence,

The number of unique permutations of the letters CORRIDOR is 3360.

The number of unique permutations of the letters NUMBER is 720.

A rental car company charges $53.75 per day to rent a car and $0.12 for every mile driven. Jaya wants to rent a car, knowing that: She plans to drive 125 miles. She has at most $230 to spend. Write and solve an inequality which can be used to determine xx, the number of days Jaya can afford to rent while staying within her budget.

Answers

Answer:

Jaya can afford to rent a car 4 days while staying within her budget.

Step-by-step explanation:

The inequality would have to indicate that the cost of renting a car has to be less than or equal to $230. The cost to rent a car is equal to the cost per day for the number of days plus the price per mile for the number of miles, which is:

53.75x+0.12y≤230, where:

x is the number of days the car is rented

y is the number of miles driven

As the statement says that she plans to drive 125 miles, you can replace "y" with this value and solve for x:

53.75x+0.12(125)≤230

53.75x+15≤230

53.75x≤230-15

53.75x≤215

x≤215/53.75

x≤4

According to this, the answer is that Jaya can afford to rent a car 4 days while staying within her budget.
