Answer: Each student will have 12 pencils.

Step-by-step explanation:

Given:  Total students= 25

Total colored boxes = 15

Total pencils in 1 box =20

Then total pencils in all 15 boxes = 20 × 15 = 300

Now, the number of pencils each students will get = (Number of pencils in all 15 boxes) ÷ (Total students)

= 300÷ 25

= 12

Therefore, Each student will have 12 pencils.

Answer:

0.00570776255

Step-by-step explanation:

there are 8760 hours in a year

divide 50 by 8760

0.00570776255

The number of earth quakes per hour is 5.7077.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given:

In one year = 50,000 occurs

In one year = 365 days

In 1 day = 24 hour

In 365 days= 8760 hours

So, number of earthquakes occurred in one hour

=50000/8760

=5.7077

Miles is a measure of distance. Acres is a measure of area, and grams is a measure of mass. Knowing this you should know that these two are the answer. Your welcome!

The lines AB and CD are parallel lines.

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

The slope of line AB is m=2+1/-4+8

m=3/4

The slope of line CD is m=9/12=3/4

Both the lines AB and CD having the same slopes.

In parallel lines the slope will be same.

Hence, the lines AB and CD are parallel lines.

Step-by-step explanation:

Answer:

$107.10

Step-by-step explanation:

The original price of the CD player is $120 and we need to take 15% off.

We can find how much we need to subtract by multiplying 120 by .15, which equals 18. Then we can subtract that from 120, to get a sales price of $102.

A shortcut is subtracting 15 from 100 to get 85, and then doing 120*.85 = 102.

From the sales price of 102, there's a 5% tax to add on. 102 * .05 = 5.1

102+5.1 = 107.1

Answer:

$107.10

Step-by-step explanation:

First, find the discount.

Multiply the discount rate, 15% by the price of the CD player, $120

discount rate * price

15% * $120

Convert 15% to a decimal. Divide 15 by 100 or move the decimal place two spots to the left.

15/100= 0.15      or        15.0 --> 1.5 --> 0.15

0.15 * $120

$18

Since it is a discount, subtract $18 from the regular price of $120.

$120-$18

$102

Next, find the tax.

Multiply the tax rate, 5% by the price of the discounted CD player, $102

tax rate * discounted price

5% * $102

Convert 5% to a decimal. Divide 5by 100 or move the decimal place two spots to the left.

5/100= 0.05    or        5.0 --> 0.5 --> 0.05

0.05* $102

$5.10

Since it is tax, add $5.10 to the discounted price of $102.

$102 + $5.10

$107.10

Russell will pay $107.10 for the CD Player after a discount and tax.

Answer:

19:95

Step-by-step explanation:

Spanish club have 19 students

Baseball have 24 students

Drama have 15 students

Home work help have 17 students

Soccer have 20 students

The first step is to calculate the total number of students

= 19 + 24 + 15 + 17 + 20

= 95 students

Since the Spanish club have 19 students and the total number of students is 95 then, the ratio which compares the number of students in Spanish club to the total number of students is 19:95

Answer: 19:95, 19 to 95, or 19/95. They all equal the same so it depends which one is your option. ORDER OF RATIO MATTERS!!

Explanation: The students in the Spanish club are 19 and to find the total number of students, you add 19 + 24 + 15 + 17 + 20 which equals 95. Then you put 19 first then 95. This is because it asked to compare the number of students in the Spanish clubs (so this is first) to the the total number of students (so this is second).

  2 times one-half = 1

Step-by-step explanation:

In order to show a property of multiplication, the equation must involve multiplication. There is only one choice that does.

  2 times one-half = 1

__

The multiplicative inverse of a number, multiplied by the number, results in 1, the multiplicative identity element.

Equation C,2 times one-half = 1 shows the inverse property of multiplication. Option C is correct.

A multiplicative inverse is a number whose value is equal to 1 when multiplied by the original number.

The left-hand side of the equation is;

LHS =  2 times one-half

LHS = 2×(1/2)

LHS = 2

The right-hand side of the equation is;

RHS =1

If both LHS and RHS are equal and the RHS value is equal to 1 the RHS is the multiplicative inverse of LHS.

Equation C,2 times one-half = 1 shows the inverse property of multiplication.

Hence, option C is correct.

perimeter = 52

Step-by-step explanation:

side of square = 2x + 1

p = 4 × s (side)

p = 4(2x +1)............. from the given

p = 8x + 4...... we will come back for this equation

side of trianles = 2x,2x,3x + 10

p = s + s + s ( all the three sides)

p = 2x + 2x + 3x + 10

p = 7x + 10........we got another equation we will use it later

8x + 4 = 7x + 10

8x - 7x = 10 - 4

x = 6 ... now lets substitute x

8x + 4

8 × 6 +4

48 + 4
