On Sunday,1/16 of the people who visited were senoir citizens,3/16 were infants,3/8 were children,and 3/8 were adults. How many of each group visited the zoo on Sunday?

Answer & Step-by-step explanation:

To multiply two fractions you have to multiply the numerators and the denominators.

1/2 × 5/8 = 5/16

3/5 × 5/9 = 15/45 = 1/3

3/8 × 2/5 = 6/40 = 3/20

to make mixed numbers improper fractions, you have to multiply the denominator by the whole number and then add the numerator to it. So the new number becomes the numerator while the denominator stays as the denominator.

2 3/8 × 16= 19/8 *16/1 = 38

If the numerator of the one fraction is the same as the denominator as the other fraction, they cancel out.

1 4/5 × 5/12 = 9/5 × 5/12 = 9/12

1 2/10 × 5 = 12/10 × 5/1 = 60/10 = 6

Answer:

Step-by-step explanation:

Final answer:

To form an equation with a sum of 34 using three numbers, one possible combination is 10, 12, and 12, resulting in the equation 10 + 12 + 12 = 34.

Explanation:

To find a combination of 3 numbers that equal 34, we can use simple addition. For example, let's choose three numbers such as 10, 12, and 12. Adding these together, we get the equation 10 + 12 + 12 = 34. This is just one of many possible combinations that satisfy the condition.

If we wanted a methodical approach to find different combinations, we could start with the first number and systematically increase it while decreasing one of the other numbers. It's important to test different combinations and remember that you can also use the same number more than once as we did with the number 12.

Remember, an equation must have an equal sign, while an expression is just a group of numbers and operations. In this case, we are looking for an equation since we want to show that the sum of the three numbers we pick is equal to 34.

Answer:

The shorter piece is 5 ft long.

The longer piece is 15 ft long.

Step-by-step explanation:

Let's write this into an equation:

(5+2x)+x=20

5+3x=20

Subtract 5 from both sides

3x=15

x=5

The shorter piece is 5 ft long.

The longer piece is 5 feet longer than 2 times 5 ft (the shorter piece).

5+2*5

5+10

15

The longer piece is 15 feet long.

The cost of the pen in terms of b is (2b - 6) dollars.

To write the cost of the pen in terms of b, we need to determine the cost of the pen relative to the cost of the markers.

Let's assign a variable to the cost of the shoulder bag. Since the shoulder bag costs twice as much as the box of markers, we can write the cost of the shoulder bag as 2b dollars.

Now, the pen costs $6 less than the shoulder bag, so the cost of the pen can be written as (2b - 6) dollars. Therefore, the cost of the pen in terms of b is (2b - 6) dollars.

The value of the fraction varies in nature that's why the value of the product got decreased and increase.

Fraction is defined as the number of compositions that constitute the Whole.

here,
Case 1, when the value of the fraction is greater than 1, the value will increase when multiplied with a certain value.

Case 2 , when the value of the fraction is less than 1, the value will decrease when multiplied by a certain value.

Answer:

40 minutes

Step-by-step explanation:

In the red line and the blue line trains just arrived at the station.

The red line arrives every eight minutes.

The Blue Line arrives every 10 minutes.

Next they will arrive at the station at the same time, LCM of 8 minutes and 10 minutes.

Because both train will come at same multiple of 8 and 10.

Factor of 8 : 2 × 2 × 2

Factor of 10 : 2 × 5

LCM : 2 × 2 × 2 × 5 = 40

Hence, After 40 minutes both train will arrive at station at same time.

The solution to the quadratic equation is x = 2 ± √3

A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.

The roots of the quadratic equations are

x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )

where ( b² - 4ac ) is the discriminant

when ( b² - 4ac ) is positive, we get two real solutions

when discriminant is zero we get just one real solution (both answers are the same)

when discriminant is negative we get a pair of complex solutions

Given data ,

Let the quadratic equation be represented as A

Now , the value of A is

x² + 4x + 1 = 0   be equation (1)

And , roots of the quadratic equations are

x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )

On simplifying , we get

x = [ -4 ± √ ( 4 )² - ( 4 ) ( 1 ) ( 1 ) ] / 2

x = [ -4 ± √ ( 16 - 4 ) ] / 2

x = [ -4 ± √12 ] /2

On further simplification , we get

x = [ -4 ± 2√3 ] /2

x = 2 ± √3

Therefore , the value of x is 2 + √3 or 2 - √3

Hence , the roots of the quadratic equations is x = 2 ± √3

Answer:

The answer is 33 bouncy balls in each machine

Step-by-step explanation:

In order to determine the answer, we need to divide every bouncy ball bags by two. The information about the amount of balls in every bag is:

bag 27 mm= 180 balls

bag 40 mm= 80 balls

The bag of 27 mm has an even amount of balls, so if we divide it by two, there will be 90 balls in each machine.

The bag of 40 mm has an even amount of balls, so if we divide it by two, there will be 40 balls in each machine.

Finally, considering the division in every bag, each machine has 130 balls.

The height of the box will be 5 inches considering the ribbon is wrapping over the perimeter along the height.

Perimeter is the addition of an external measure of sides it will always positive.

A perimeter is a length and has a degree of the unit as one.

For example

Perimeter of square = side + side + side + side

The perimeter of the circle = πd where d is the dia of the circle.

The total length of the ribbon = is 70 inches.

The bow takes 32 inches of ribbon.

So left = 70 - 32 = 38 inches.

Now,

38 inches = Perimeter along the height

2 ( L + 14 ) = 38

L + 14 = 19

L = 5 inches.

Hence "The height of the box will be 5 inches considering the ribbon is wrapping over the perimeter along the height".

Step-by-step explanation:

x(2•x)= 4•5•y

Expand brackets,

2x•x²=20•y

Multiply.

2x³ = 20y

Divide both sides by 2.

x³ = 10y

Take cube root.

x = ∛10y

2x³ = 20y

Divide 20 on both sides.

1/10x³ = y

Answer:

[tex] y = \frac{ {x}^{3} }{10} [/tex]

Step-by-step explanation:

[tex]x(2 \times x) = 4 \times 5 \times y \\ 2x \times {x}^{2} = 20y \\ 2 {x}^{3} = 20y \\ \frac{ 2{x}^{3} }{20} = \frac{20y}{20} \\ y = \frac{ {x}^{3} }{10} [/tex]

The total hours worked over the weekend are 44 hours, resulting in gross wages of $880.

To calculate the gross wages for the weekend, we need to multiply the hours worked each day by the hourly pay rate of $20. On Friday and Saturday, the working hours are from 7am to 11pm, which is 16 hours each day. On Sunday, the working hours are from 9am to 9pm, which is 12 hours.

To find the total hours worked over the weekend, we add the hours for each day:

Now we calculate the total hours: 16 + 16 + 12 = 44 hours.

Next, we calculate the total earnings by multiplying the total hours by the hourly rate:

= 44 hours x $20 per hour = $880.

Therefore, the gross wages for the weekend work are $880.
