A piece of wire is 8/9 meter long broke into two pieces. One piece is 2/3 meter long. How long is the other?
Genrish500 [490]

Answer:

<h2><em><u>2/9 is the answer.</u></em></h2>

Step-by-step explanation:

<em><u>1. First, make an equation.</u></em>

<em><u>Given:</u></em>

8/9 = length of wire

2/3 = length of a part of the wire

E = 8/9-2/3

<em><u>Unknown:</u></em>

Second part of wire

<em><u>2. Make the numbers have equal denominators</u></em>

2/3 * 3/3

= 6/9

<em><u>3. Solve</u></em>

8/9 - 6/9

= 2/9

Hope this helped,

Myesha finds some nickels and quarters under the couch cushions. How many coins does she have if she has 6 nickels and 12 quarte
Advocard [28]

If Myesha found 6 nickels and 12 quarters under her cushion, this means that she has a total of 18 coins.

<h3>What is an equation?</h3>

An equation is an expression used to show the relationship between two or more variables and numbers.

Let x represent the number of nickels and y represent the number of quarters. There are 2 cups in 1 pint. Hence:

If she has 6 nickels and 12 quarters:

Number of coins = 12 + 6  = 18

If she has x nickels and y quarters:

Number of coins = x + y  

If Myesha has 6 nickels and 12 quarters, this means that she has 18 coins.

The equivalent numbers of 12/20 are 60% and 0.60

<h3>How to convert the fraction?</h3>

The fraction expression is given as:

12/20

Multiply the fraction expression by 100%

So, the expression becomes

12/20 * 100%

Evaluate the product

60%

Express as fraction, again

60/100

Evaluate the quotient

0.60

Hence, the equivalent numbers of 12/20 are 60% and 0.60

Suppose an object is launched from ground level directly upward at 57.4 f/s Write a function to represent the object’s height ov
Semmy [17]

Answer: p(t) = (-16 ft/s^2)*t^2 + (57.4 ft/s)*t

Step-by-step explanation:

We can suppose that the only force acting on the object is the gravitational force, then the acceleration of the object will be equal to the gravitational acceleration.

Then we can write:

a(t) = -32 ft/s^2

Where the negative sign is because this acceleration is downwards.

Now, to get the vertical velocity of the object, we need to integrate over time to get:

v(t) = (-32 ft/s^2)*t + v0

where t represents time in seconds and v0 is the constant of integration, and in this case, is the initial vertical velocity.

In this case, the initial velocity is 57.4 ft/s upwards, then the velocity equation is:

v(t) = (-32 ft/s^2)*t + 57.4 ft/s

To get the position equation we need to integrate over time again, to get:

p(t) = (1/2)*(-32 ft/s^2)*t^2 + (57.4 ft/s)*t + p0

Where p0 is the initial height of the object, as it was launched from the ground, then the initial position is p0 = 0ft.

then the position equation (that is the function that represents the height of the object as a function over time) is:

p(t) = (1/2)*(-32 ft/s^2)*t^2 + (57.4 ft/s)*t

p(t) = (-16 ft/s^2)*t^2 + (57.4 ft/s)*t
