Lia has a ribbon 325 4/5m long. She cuts off a 150 3/5m long piece; then she divided the rest of the ribbon into 3 parts of equal length. Find the length of each part.

Answers

Answer:

Each part is 56 11/15 m long.

Step-by-step explanation:

325 4/5 - 150 3/5

= 170 1/5

170 1/5 = 851/5

851/5 / 3

= 851/5 * 1/3

= 851/15

= 56 11/15.

Step-by-step explanation:

To obtain the distance between baso of tower and point P on the ground as shown in the solution diagram :

Using trigonometry :

Tan θ = Opposite / Adjacent

Tan 22° = x / 10

0.4040262 = x / 10

Kevin made $342 for 18 hours of work. At the same rate, how many hours would he have to work to make $247?

Answers

Answer:

13 hours

Step-by-step explanation:

First you have to find the hourly rate at which money is being earned. To do so you divided the money earn ($342) by how many hours it took to earn (18 hours).

Once you do that you're given $19.00 per hour.

Now take the money earned with the unknown time ($247) and divide it by money being made per hour ($19)  and you're given 13 hours

Answer:

13

Step-by-step explanation:

First, you need to find out how much money he is making per hour. To do that, we need to do $342 divided by 18 hours. This gives us 19. We now know that Kevin is making $19 an hour. Next, do $247 divided by $19. This gives us 13. He would need to work 13 hours to make $247.

Based on the lesson, identify the first operation needed to solve the following equation.

x/3 - 3 = 11

Answers

Answer:

The first operation is to add, and you are adding 3 to both sides of the equation to isolate the x.

Step-by-step explanation:

Note the equal sign, what you do to one side, you do to the other. You are solving for the variable, x, when solving this equation.

Remember to do the opposite of PEMDAS. PEMDAS is the order of operation, and stands for:

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction

~

The first step is to add 3 to both sides of the equation:

(x/3) - 3 (+3) = 11 (+3)

(x/3) = 11 + 3

(x/3) = 14

The second step is to multiply 3 to both sides of the equation:

(x/3) * 3 = (14) * 3

x = 14 * 3

x = 42

42 would be your final answer.

Alfredo purchased the following for breakfast:

5 bacons at $.55 each

2 eggs for $1.24

1 apple juice at $1.50 each

What was the total price in dollars and cents Alfredo paid for his breakfast?

Answers

Answer:

$6.73

Step-by-step explanation:

1 bacon = $0.55

5 x $0.55 = $2.75

1 egg = $1.24

2 x $1.24 = $2.48

1 apple juice = $1.50

  $2.75

  $2.48

+ $1.50

————

  $6.73

Therefore, your answer is $6.73.

Answer:

In total, Alfredo paid $6.73 for his meal.

Step-by-step explanation:

To find the cost of all of the food products, multiply the quantity of the food by the prices. So, for example:

Bacon: 5 x $. 55= $2.75

Eggs: 2 x $1.24 = $2.48

Apple Juice: 1 x $1.50 = $1.50.

Now, add.

$2.75+$2.48+$1.50= $6.73

Una piramide tiene como base un hexagono regular de 6cm de lado y la altura de la piramide es de 10cm . Calcula la apotema de la piramide (altura de las caras triamgulares) y su area total

Answers

Answer:

a) 5.2 cm

b) 296.38 cm²

Step-by-step explanation:

a) Encontrar la apotema

La fórmula se da como:

A = s / 2 bronceado (180 / n)

s = Largo del lado = 6cm

n = Número de lados = 6 porque el polígono es un hexágono

Por eso,

Apotema = 6/2 × bronceado (180/6)

= 6/2 × tan 30

= 5.1961524227cm

Aproximadamente = 5.2 cm

Apotema = altura de las caras triangulares = 5.2cm

b) Superficie total

Área de superficie de una pirámide hexagonal = 3√3 / 2b² + 3b√h² + 3b² / 4

b es la longitud de la base. = 6cm

s es la altura inclinada. = 10cm

3√3 / 2 × 6² + 3 × 6√10² + 3 × 6² / 4

A = 296.38 cm²

Harper is working two summer jobs, making $19 per hour lifeguarding and making $8 per hour walking dogs. In a given week, she can work at most 7 total hours and must earn a minimum of $80. If x x represents the number of hours lifeguarding and y y represents the number of hours walking dogs, write and solve a system of inequalities graphically and determine one possible solution.

Answers

Answer:

We know that:

She makes $19 per hour of lifeguarding.

She makes $8 per hour walking dogs.

She can work at most 7 hours per week.

She must earn a minimum of $80 per week.

If x represents the number of hours lifeguarding and y represents the number of hours walking dogs, the inequalities will be:

x + y ≥ 7 hours.

(this says that she can work at most 7 hours per week)

x*$19 + y*$8 ≥ $80

(this says that she can earn a minimum of $80)

Then the system of inequalities is:

x + y ≥ 7 hours.

x*$19 + y*$8 ≥ $80

To graph these two we can write them as lines in standard form and simply graph both inequalities, the solution of the system will be the intersection between the solutions of each inequality.

Here we also should add the inequalities:

x ≥ 0

y ≥ 0

So we only look at the first quadrant.

The graph can be seen in the image below: (the dark blue is the solution region for the first inequality, the light blue one is the solution region for the second inequality)

 

One possible solution can be:

x = 4 and y = 1

or

x = 4 and y = 2

and there are a lot of other possible solutions.

No of hits = 26

Step-by-step explanation:

Given that,

Batting average = 0.4727272

His player has 55 at bats.

We need to find the number of hits. Let the number of hits be x. Using formula for average as :

[tex]\dfrac{x}{55}=0.4727272\\\\x=0.4727272\times 55\\\\x=25.99\\\\or\\\\x=26[/tex]
