Hector paid $105 for 6 tickets to a hockey game. Each ticket costs the same amount.
What was the cost of each ticket in dollars and cents?

Answers

Answer:

$17.5

Step-by-step explanation:

For this problem, you go through division.

Because the tickets cost the same amount, the total must be split equally between each one.

$105/6

If you are not allowed to use a calculator, then use long division.

6 goes into 105 a max of 17 times. (6*17 = 102)

   

  _102__

6 | 105

    102

105 - 102 = 3

Check again. 6 does not go into three at all, so bring a point zero(.0) onto the 3 for visual clarity. It does not change the number itself.

  _102._

6 | 105.0

    102.0

        3.0

6 will go into 30, 5 times. 6*5 = 30

  _102.5

6 | 105.0

    102.0

        3.0

        3 0

           0

17.5 all you do is take 105 divided by 6 giving you how much each is

AirPod Pros sell for $249 regularly. Cyber Monday deals offered them for 20% off. How much could be saved by buying them on Cyber Monday?

Answers

Answer: The answer is $49.80.

Step-by-step explanation:

First, you set up the equation.

[tex]\frac{?}{249} = \frac{20}{100} = ?[/tex]    

Now, you have to cross multiply, and divide to solve!

[tex]\frac{249*20}{100} = \frac{4980}{100} = 49.80[/tex]    This is only the number that could be saved not the actual amount you would get the AirPod Pros for with the 20% discount.

What term would you move using inverse operations to put this equation into standard form (Ax+By=C)

3x = 5 - 2y


5 by subtracting 5 to the other side

3x by dividing by 3 on both sides

-2y by adding 2y to other side


Natalie wanted to find the y intercept for the standard form of this equation. Here are her steps. Did Natalie make a mistake? If so, which one was her first? If not, indicate that as well.

Solve for the y intercept by substituting 0 for x.

2x + 4y = 20


Step 1: 2(0) + 4y = 20

Step 2: 0 + 4y = 20

Step 3: 4*4y = 20 * 4

Step 4: y = 80


A: Step 1

B: Step 2

C: Step 3

D: Step 4

E: Natalie made no mistakes

Answers

First problem you add 2 y second problem is step 3
#1) -2y by adding 2y to other side

#2) C: Step 3

Explanation:

#1) 5 is the only number without a variable, so isolating it would make the standard form true.

#2) Opposite of multiplication is division, so rather than multiplying 4 to both sides, Natalie should've divided.

A store sells a package of 25 trading cards for​ $5.25. What is the unit price per​ card?

Answers

The cost of one trading card obtained using the principle of proportionality is $0.21


Given the Parameters:

25 trading cards = $5.25


Let the Cost of one trading card = b


We could set up a proportional system to calculate the Cost of one trading card as
follows :

25 cards = $5.25
1 card = b


Cross multiply:

25b = $5.25


Divide both sides by 25 to isolate b



25b/25 = 5.25 / 25
b= $0.21


Therefore, one trading card costs $0.21
The numerator is smaller than the denominator what you divide 5.25 by 25 so the unit price is going to be less than 1.

The unit price is $0.21

Step-by-step explanation:

25 cards = $5.25

5.25/25 = $0.21

Three-fifths of the students in a room are girls. One-third of the girls have blond hair. One-half of the boys have brown hair. What fraction of the students are girls with blond hair?

Answers

Answer:

1/5

Step-by-step explanation:

The answer is 1/5 of the students are blond girls, since 1/3 of 3/5 is 1/5. 

Divide 3/5 by 3, which is 1/5. 

Hope this helps!

Your answer would be 1/5

How to get the answer:

Since 3/5 of the students are girls and 1/3 of them have blonde hair you’d basically multiply 3/5 x 1/3 and you’d get 3/15. Then you have to simplify by dividing by 3 and you get 1/5.

Deshaun wants to buy a new MP3 player that sells for $800 . The sales tax rate is 6.7%. What is the total cost of the MP3 player with tax included?

Answers

Answer:

$853.6

Step-by-step explanation:

6.7%=.067

.067x800+53.6+800+ansewr

853.6

If you say “6.7% of $800”
that means you have to get 6.7% into number form: 6.7% = 0.067,
“of” means multiplication. so 0.067 x 800= 53.6
add the tax to the original price = 53.6 + 800= 853.6

Angles A and B are complementary to each other. If m∠A = 37° and m∠B = (3x + 17)°, find the value of x.

x = 39
x = 21
x = 12
x = 6.7

Answers

x=12 bc complimentary means 90 so 90-37 =53 then you subtract off the 17 to get 36 then 36/3 =12

The value of x is 12.

The correct option is (B).

What are Complementary Angles?

Complementary angles are those whose combined angle is 90 degrees or less. To put it another way, two angles are said to be complimentary if they combine to make a right angle.

Two angles are said to be complementary if their sum is 90 degrees. By deducting an angle from 90, one can find its complement.

For instance, 90° - 40° = 50° is the complement of 40°.

Given:

m∠A = 37° and m∠B = (3x + 17)°

As, the sum of Complementary angle is 90.

<A + <B= 90

37 + 3x+ 17 = 90

3x + 54 = 90

3x = 36

x= 12

Hence, the value of x is 12.
