-14n + q = rt - 4n
q - rt = -4n + 14n
q - rt = 10n
(q - rt) / 10 = n

N = -1/10rt + 1/10q
= −14n+q+4n=rt−4n+4n
= −10n+q=rt
= −10n+q+−q=rt+−q
= −10n=rt−q
= -10n/-10 = rt-q/-10
So the answer is:
= n = -1/10rt + 1/10q

The cost, in dollars, of manufacturing x microwaves is 6,000 + 300x dollars. The amount received when selling these x microwaves

densk [106]

Answer:

21 microwaves

Step-by-step explanation:

The net profile is equal to the income less the total cost, so the equation to the net profile NP is:

NP = 700x - (6000 + 300x)

Where 700x is the income and (6000+300x) is the cost of manufacturing.

Now, replacing NP by 2400 and solving for x, we get:

2400 = 700x - (6000 + 300x)

2400 = 700x - 6000 - 300x

2400 + 6000 = 400x

8400 = 400x

$\frac{8400}{400}=x\\ 21=x$

So, the least number of microwaves that must be manufactured and sold so that the net profit is $2400 is equal to 21.

The balance of errands average balance checking account at the beginning of last cycle was $400 and the only transaction for the

Tom [10]

Answer:

$300

Step-by-step explanation:

Here we are given:

Balance at the beginning of last cycle(first half) = $400

Balance halfway through the cycle(second half cycle) = $200

To find the amount Aaron's checking account pay interest last cycle, let's find the average balance.

Use the formula for average:

$\frac{Bal 1 + Bal 2}{2}$

$\frac{400 + 200}{2}$

$\frac{600}{2} = 300$

Average = $300

Therefore, the amount Aaron's checking account pay interest last cycle is $300

Dylan has a square peice of metal that measures 10inches on each side he cuts the metal along the diagonal, forming two right tr

poizon [28]

Since it is a square, both the length and the width are equal. Both are 10 inches.

We will use Pythagoras Theorem to find the diagonal of the square.

$\boxed { \boxed {a^2 + b^2 = c^ }}$

$c^2 = 10^2 + 10^2$

$c^2 = 100 + 100$

$c^2 = 200$

$c = \sqrt{200}$

$c = 14.1 \text { inches}$

$\boxed {\boxed {\text {Answer: The hypotenuse is 14.1 inches}}}$

And angle measures 54° more than the measure of its complementary angle what is the measure of each angle

Mashutka [201]

Answer:
The measure of the angles are 72 degrees and 18 degrees
Step-by-step explanation:
we know that
If two angles are complementary, then their sum is equal to 90 degrees
Let
x -----> the measure of an angle
y-----> the measure of he other angle
we know that
x+y=90 -----> y=90-x -----> equation A
x=y+54 ----> equation B
substitute equation B in equation A and solve for y
y=90-(y+54)
y=90-y-54
2y=36
y=18°
Find the value of x
x=y+54 -----> x=18+54=72°
therefore
The measure of the angles are 72 degrees and 18 degrees
