The formula for the area of a trapezoid is A=1/2h(b1+b2) express b1 in terms of A, h and b2

Answers

Answer 1

Answer:

The expression of b1 in terms of A, h, and b2 is expressed as $b_1 =(2A)/(h) - b_2$

Given the formula for calculating the area of a trapezoid expressed as:

$A = (1)/(2)h(b_1+b_2)$

We are to express b1 in terms of A, h, and b2 as shown

$A = (1)/(2)h(b_1+b_2)\n2A = h(b_1+b_2)\n(2A)/(h) = b_1 + b_2\n b_1 =(2A)/(h) - b_2$

Hence the expression of b1 in terms of A, h, and b2 is expressed as $b_1 =(2A)/(h) - b_2$

Enter the value of p so the expression 5/6 - 1/3n equivalent to p(5-2n)

Answers

You said 5/6 - 1/3 n = p (5 - 2n)

Divide each side by (5 - 2n) :

   p = (5/6 - 1/3 n) / (5 - 2n) .

That's about all you can do with it.
As you can see, the required value for 'p'
depends on the value of 'n'.

If you want to get rid of those awkward fractions,
I guess you could multiply top and bottom by 6 .
Then you have ...

   p = (5 - 2 n) / 6·(5 - 2n) .

Oh, my goodness ! Look at that !

   p = 1/6 .

It doesn't even depend on 'n' at all. It's always true,
no matter what 'n' is.

I am surprised.

Answer:

Step-by-step explanation:

Let x

Then we have 15 (x + 9) = 420.

We can divide both side by 15, getting x + 9 = 28. Then, we can subtract both sides by 9, getting x = 28 - 9 = 19.

Since there are 15 players and he bought a basketball for each of them, he bought 15 basketballs in total.The price of a basketball costs $9.The total price of all 15 basketballs = $9 * 15 = $135.He spent $420 on uniforms and basketballs, and he spent $135 on basketballs.Thus, he spent $420 - $135 = $285 on uniforms.As he bought a uniform for each of the 15 players, he bought 15 uniforms in total.The price of 15 uniforms is $285.The price of 1 uniform is $285 ÷ 15 = $19.

To best estimate the quotient in scientific notation. what number should replace m?6.33x 10

1.79x 103

3 x 10"

Answers

Answer:

m = 4

Step-by-step explanation:

The complete question is:

Given:

6.33 x 10⁹ / 1.79 x 10⁵ ≈ 3 x $10^(m)$

To find:

To best estimate the quotient in scientific notation. what number should replace m?

Solution:

The equation is:

6.33 x 10⁹ / 1.79 x 10⁵ = 3 x $10^(m)$

Let x = 9 and y = 5 then the above equation becomes:

6.33 x $10^(x)$ / 1.79 x $10^(y)$ = 3 x $10^(m)$

Since we know that the exponent property is:

quotient $quotient (z^(x) )/(z^(y) ) = quotient z^(x-y)$

Now converting the given equation in the form above we get:

6.33 / 1.79 x $10^(x-y)$

6.33 / 1.79 x $10^(9-5)$

Now the quotient is 6.33/1.79 ≈ 3.536313

quotient x $10^(9-5)$

3.536313 x $10^(9-5)$

Since 9-5 = 4 So

3.536313 x $10^(4)$

3.536 x $10^(4)$

Hence

6.33 x 10⁹ / 1.79 x 10⁵ ≈ 3.5 x $10^(4)$

Hence m = 4

If a chicken farm sold 3,000 dozen eggs last week, how many individual eggs were sold?

Answers

The correct answer for how many individual eggs were sold is 36,000.

To find the number of Individual eggs sold, calculate total number of eggs in 3,000 dozen.

What is Dozen?

A dozen is a term used when to group a total of 12 items together.

The items can be of any category like 12 fruits, 12 pencils.

One dozen = 12.

In given question, The item sold is eggs.

To find the total number of eggs, multiply the dozen eggs sold by 12.

Number of dozen eggs sold = 3,000.

Total number of Individual eggs sold is:

= 3000 dozen × 12 eggs/dozen.

= 36,000.

The count of individual eggs sold is 36,000.

Solve −2x − 13 = 8x + 7. (1 point)

−2
2
−6
6

Answers

To solve for the value of x, it is easiest by isolating "x" to one side of the equation. This method is shown below:

-2x - 13 = 8x + 7

Adding 2x to both sides:

-2x - 13 + 2x = 8x + 7 + 2x
-13 = 10x +7

Subtracting 7 from both sides:

-13 - 7 = 10x + 7 - 7
10x = -20

Dividing both sides by 10:

10x / 10 = -20 / 10
x = -2

solve:
-2x-13=8x+7
-2x-8x=7+13
-10x=20
-x=20/10
-x=2
x= -2
THE ANSWER IS -2
