Hi, need help on this really bad pls (:

Answer:

0.75%

Step-by-step explanation:

First, do 3 divided by 4 which is 0.0075. But this is in decimal form, so we have to multiply this by 100. 0.0075 x 100 is 0.75, so therefore the fraction, 3/400 as an percentage is 0.75%. I hope this makes sense!

Answer:

The sample size is  n=246

Step-by-step explanation:

The quotient for the division of given decimal numbers is 62.

Given that, 142.6 divided by 2.3.

The division is one of the basic arithmetic operations in math in which a larger number is broken down into smaller groups having the same number of items.

Here, 142.6 divided by 2.3 [tex]=\frac{142.6}{2.3}[/tex]

[tex]=62[/tex]

Therefore, the quotient for the division of given decimal numbers is 62.

Answer:

54 hours

Step-by-step explanation:

9 hours everyday, so you just mulitply the amount of the hours to the amount of days. equation: 9x6

The hours is the store open each week would be 54 hours

Suppose a, b and c are three numbers. Then we have:

a(b + c) = a x b + a x c

(a(b+c) means a multiplied to (b+c). The sign of multiplication is usually hidden when using symbols and both quantities which are in multiplication are written together without space). This property is known by distributive law and applies to subtraction also.

Given that store is open 9 hours each day. It is open for 6 days each week.

Using Distributive property with multiplication and subtraction;

we just need to multiply the number of hours by the number of days. equation:

9 hour every day

9  x 6 = 54 hours

Hence, 54 hours every day the store is open each week.

PRELIMINARY

Fractions are part of a whole. For example, if an object is divided into two equal parts, the value of each part is half or one-half of the total number of objects. Fractions can be expressed in the form:

[tex] \frac{a}{b} [/tex]

DISCUSSION

Fractions also have fractions in different forms but have the same value which are called equivalent fractions. Fractions can also be simplified. To find a fraction equal to a fraction, we can multiply (×) or divide (÷) the numerator and denominator of the fraction by the same number. And to simplify fractions, we can divide (÷) the numerator and denominator of the fraction with the same number.

**

There are various forms of fractions, including:

**

Now from the discussion above, it turns out that ordinary fractions still have two more types, namely =

➳ A pure fraction is a fraction whose numerator is smaller than the denominator.

➳ An impure fraction is a fraction whose numerator is greater than its denominator.

Answer:

Step-by-step explanation:

Pick two points and calculate the slope (Rise/Run).

I picked (-2,0) and (2,-2)

Rise = (-2 - 0) = -2

Run = (2-(-2)) = 4

Slope (Rise/Run) = -2/4 or -1/2

The line has an intercept of -1  (the "b" in y=mx + b)

So the equation is y = -(1/2)x -1

b = 5.5m a = 6m

b = 17cm a = 80cm

Step-by-step explanation:

The second triangle in the pair is a scaled-up version of the first triangle.

To find b in the first triangle you do 11/2 = 5.5m

To find a in the second triangle you do 3*2 = 6m

To find b in the third triangle you do 68/4 = 17cm

To find a in the fourth triangle you do 20*4 = 80cm

Cheyenne's rental car will cost $124.45

Step-by-step explanation:

300(mi driven)-200(mi allowed)=100 miles that must be paid for

100*.18(cost per mile)=18.00

99.96+18.00=117.96

117.96*.055(5.5% tax rate)=6.49

117.96+6.48=124.45

Bounces in the horizontal plane

Balon7.gif (2174 bytes)  

When a ball bounces off a rigid board, the component of the velocity perpendicular to the board decreases in value, leaving the parallel component unchanged

v x = u x

v y = -e u y

Heights of successive bounces

Suppose a ball is dropped from an initial height h . We are going to calculate the heights of the successive bounces.

1.-First bounce

The velocity of the ball before it hits the ground is calculated by applying the principle of conservation of energy

The velocity of the ball after the collision is (in modulus) v 1 = e u 1

The ball ascends with an initial velocity v 1 , and reaches a maximum height h 1 which is calculated by applying the principle of conservation of energy

2.-Second bounce

The velocity of the ball before it hits the ground is calculated by applying the principle of conservation of energy

The velocity of the ball after the collision is v 2 = e u 2

The ball ascends with an initial velocity v 2 , and reaches a maximum height h 2 which is calculated by applying the principle of conservation of energy

3.-Bounce n

After collision n , the maximum height the ball reaches is

h n = e 2n h

Loss of energy experienced by the ball

In the first collision, the ball loses an energy

In the second collision, the ball loses an energy

In the collision n the ball loses an energy

The sum of Δ E 1 + Δ E 2 + Δ E 3 +…. Δ E n is the energy lost by the ball after n collisions. After infinite collisions the ball will have lost all its initial energy mgh . We are going to check it by adding the infinite terms of a geometric progression of ratio e 2 and whose first term is Δ E 1

Time it takes for the ball to stop.

The time it takes for the ball to reach the ground when dropped from a height h from rest is

The ball bounces and rises to a height h 1 , then falls back to the ground. The time it takes to go up and down is

The ball bounces and rises to a height h 2 , and then falls back to the ground. The time it takes to go up and down is

The total time after infinite bounces is the sum of t 0 and the terms of a geometric progression whose first term is 2 t 0 e and whose ratio is e.

If the ball is given a horizontal initial velocity v x . After infinite bounces, it moves a horiz

Answer:

  (16, -23)

Step-by-step explanation:

We assume your notation means the figure is dilated by a factor of 3 with the origin as the center of dilation, then it is translated 2 units left and 4 units up.

These transformations can be written as ...

  (x, y) ⇒ (3x, 3y) . . . . . . . dilation by a factor of 3 about the origin

  (x, y) ⇒ (x -2, y +4) . . . . translation by (-2, 4)

These two transformations together give you ...

  (x, y) ⇒ (3x -2, 3y +4)

  (6, -9) ⇒ (3·6 -2, 3(-9) +4) = (18 -2, -27 +4) = (16, -23)

The point is transformed to (16, -23).

Answer:

  7(x +27) = 150

Step-by-step explanation:

Let x represent the number.

  "a number increased by 27" . . . . x +27

  "the sum multiplied by 7" . . . . . 7(x +27)

  "the result is 150" . . . . . . 7(x +27) = 150

Add the 3 ratio portions together: 1 + 4 + 7 = 12

Divide total length by 12:

84/12 = 7

Multiply each ratio portion by 7:

1 x 7 = 7

4 x 7 = 28

7 x 7 = 49

The longest piece is 49 cm

Answer:

49cm

Step-by-step explanation:

1x+4x+7x=84

12x=84

X=7

4*7=28

7*7=49

So we can see 49cm is the longest.
