Answer:

company 1 final price: $148.5

company 2 final price: $168

company 3 final price: $132

thus, the best choice is company 3 because it costs the least and all services are the same

Step-by-step explanation:

company 1 is offering 25% off the price of their service

company 2 is offering $30 off the price of their service

company 3 is offering a 1/3 discount off the price of their service

the price of the cleaning is $198

company 1: 25% discount = 75% of the original price $198, which would be $198 * 3/4, or $148.5

company 2: $30 dollars off, which means $198 - $30 or $168

company 3: 1/3rd discount, meaning the product after the discount is only 2/3rd of the original price. 2/3rd of $198 is $132, so the final price after the discount is $132

Answer:

Step-by-step explanation:

The points loosed in the first round  l = 10 points

Points gained in the second round g = 14points

Let the points loosed be negative while that gained be positive, hence;

l = -10 points

g = +14 points

Change in the integers = l+g

Change in the integers = =-10 + 14

Change in the integers = 4points

Solving the quadratic equation, it is found that it took 2.5 seconds for the ball to hit the ground.

It is given by:

h(t) = -8t² + 18t + 5.

It hits the ground when h(t) = 0, hence:

-8t² + 18t + 5 = 0.

Which has coefficients a = -8, b = 18, c = 5, then:

[tex]\Delta = 18^2 - 4(-8)(5) = 484[/tex]

[tex]x_1 = \frac{-18 + \sqrt{484}}{2(-8)} = -0.25[/tex]

[tex]x_2 = \frac{-18 - \sqrt{484}}{2(-8)} = 2.5[/tex]

It took 2.5 seconds for the ball to hit the ground.

Answer: pretty sure its A

Step-by-step explanation:

Joy will make 5 ornaments this weekend.

Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

WE have been given that Joy made 2 ornaments in 6 hours.

This weekend, Joy plans to spend a total of 15 hours making ornaments.

If joy works at the same rate Therefore,

2 ornaments is 6 hours = 2/6 ornaments/hour

= 1/3 ornaments/hour

Thus 1/3 ornaments/hour × 15 hours = 5 ornaments

Hence, She will make 5 ornaments this weekend.

Answer:

Final answer=$307.50

Step-by-step explanation:

Given:

Money Enrique makes per hour = $9.25

Total time he worked last week = 30 hours

Commission he got for $300 of sales = 10%

So, total amount of money he made in the last week is,

(Wage he gets per hour)×(No. of hours he worked)

=$9.25×30

=$277.50

Now, we have to find the money he made from the sales with commission of 10%,

= (Money made from sales)×(Commission %)

=$300×10%

=300×10/100

=3×10/1

=$30

Now we calculate the total money he made,

(Money made by working)+(Money from commission)

=$277.50+$30

=$307.50

∴Enrique made $307.50 in total from the last week.

Enrique made $307.50 in total from the last week.

A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.

Enrique makes per hour = $9.25

He worked 30 hours in a week.

Commission he got for $300 of sales = 10%

Total money

=(Wage he gets per hour)×(No. of hours he worked) + money made from the commission

=$9.25×30 + (Money made from sales)×(Commission in percentage)

=$277.50 + $300×10%

=  277.50 + 300×10/100

=$307.50

Therefore, Enrique made $307.50 in total from the last week.

8x = 32

x=32/8 = 4

boys are 4 x 5 = 20

girls are 4 x 3 = 12

Step-by-step explanation:

Add the ratios together: 5 + 3 = 8

Divide total students by 8:

32 / 8 = 4

Multiply each ratio by 4 to find the number of each:

Boys = 4 x 5 = 20

Girls = 3 x 4 = 12

There are 20 boys.

Step-by-step explanation:

Step 1: Define expression

(2x - 2) - (2x - 4)

Step 2: Simplify

We know, distance between two points A( p,q) and B(r,s) is given by :

[tex]AB=\sqrt{(p-r)^2+(q-s)^2}[/tex]

So, distance between P an Q is :

[tex]PQ=\sqrt{(-7-4)^2+(6-6)^2}\\\\PQ=11\ units[/tex]

Distance between Q and R is :

[tex]QR=\sqrt{(4-4)^2+(6-(-6))^2}\\\\QR=12\ units[/tex]

Distance between R and S is :

[tex]RS=\sqrt{(4-6)^2+(-6-(-6))^2}\\\\RS=\sqrt{4}\\\\RS = 2\ units[/tex]

Therefore, total distance is 11 + 12 + 2 = 25 units.

Hence, this is the required solution.

The probability that the bag has buttons is 0.38.

Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.

We know that, probability of an event = Number of favorable outcomes/Total number of outcomes.

Given that, a company makes 130 bags.

Here, the number of favorable outcomes = 49 and the total number of outcomes =130

Now, probability of an event = 49/130

= 0.38

Therefore, the probability that the bag has buttons is 0.38.
