Answer:5n^2-9n-7
Step-by-step explanation:
If ABCD is a rhombus containing a right angle, then DABC is a square. Can you explain your reasoning?
The opposite angles of a rhombus are congruent
It is true that rhombus ABCD is a square
A rhombus has the following features
All sides are equal.Opposites angles are equal.Adjacent angles add up to 180 degreesThe above highlights mean that:
The angle opposite the right angle is also a right angle.The angles adjacent the right angles are also right angles.So, the four angles in the rhombus are right angle, and the side lengths are equal.
Hence, the rhombus is a square

73 is 20% of what number step by step
Answer:
365
Step-by-step explanation:
(20*x) / 100 = 73
Answer:
365
Hope this helps :)
Step-by-step explanation:
We already have our first value 73 and the second value 20. Let's assume the unknown value is Y which answer we will find out.
As we have all the required values we need, Now we can put them in a simple mathematical formula as below:
STEP 173 = 20% × Y
STEP 273 =
20
100
× Y
Multiplying both sides by 100 and dividing both sides of the equation by 20 we will arrive at:
STEP 3Y = 73 ×
100
20
STEP 4Y = 73 × 100 ÷ 20
STEP 5Y = 365
Finally, we have found the value of Y which is 365 and that is our answer.
You can easily calculate 73 is 20 percent of what number by using any regular calculator, simply enter 73 × 100 ÷ 20 and you will get your answer which is 365

Assuming that a country’s population is now 3 million and is growing exponentially with growth constant 0.02, what will be the average population during the next 50 years?
Using the exponential growth principle, the population of the country in the next 50 years would be 8074764.08722
The exponential growth can be modeled using the relation :
[tex] f(t) = A(1 + r)^{t} [/tex] A = initial population value = 3,000,000r = growth rate = 0.02 t = time = 50 yearsSubstituting the values into the equation, we'll have :
[tex] f(50) = 3000000(1 + 0.02)^{50} [/tex]
[tex] f(50) = 3000000(1.02)^{50} [/tex]
[tex] f(50) = 3000000(2.6915880...) [/tex]
= 8074764.08722
Therefore, the population in the next 50 years would be 8074764.08722

(3x - 4)/8 = (x + 2)/3 Cross multiply
8(x +2) = 3(3x - 4) Remove the brackets using the distributive property
16x + 16 = 9x - 12 Subtract 16 from both sides
16x = 9x - 12 - 16 Combine
16x = 9x - 28 Subtract 9x from both sides
16x - 9x = - 28 Combine
7x = - 28 Divide by 7
x = - 4

The sum of the 3 angles in a triangle = 180°
Sum the 3 given angles and equate to 180
3x + 4 + 5x - 2 + 90 = 180
8x + 92 = 180 ( subtract 92 from both sides )
8x = 88 ( divide both sides by 8 )
x = 11

Step-by-step explanation:
help please! indicate the equation of the given line in standard form the line that contains the point q 1,2 and is parallel to the line whose equation is y-4=2/3(x-3)
9514 1404 393
Answer:
2x -3y = 8
Step-by-step explanation:
It is helpful to start by putting the given equation in standard form
y -4 = 2/3(x -3)
3y -12 = 2x -6 . . . . . . multiply by 3, eliminate parentheses
2x -3y = -6 . . . . . . . . add 6-3y to get standard form
When point Q is substituted for x and y, the new constant on the right is ...
2x -3y = 2(1) -3(-2)
2x -3y = 8
_____
Additional comment
The equation is in standard form when the leading coefficient is positive, all coefficients are mutually prime integers, and the form is ...
ax +by = c
Note that we subtracted the y-term, rather than the x-term from the given equation. This is so the x-term would have a positive coefficient. We could have written our standard form equation as ...
3y -2x = -8

-1/2(7w+4)+1/5(5w-15)
please explain how to solve. thank you
Answer:
[tex]-\frac{7w+4}{2}+w-3[/tex]
Step-by-step explanation:
Is this the correct statement?
[tex]-\frac{1}{2}(7w+4)+\frac{1}{5}(5w-15)[/tex]
If so, here's how. While we're here, you don't actually "solve" an expression, you can only simplify it. Solving it implies solving an equation, and that needs an = sign.
Starting on the left. First, distribute the fraction over the parenthesis:
[tex]-\frac{7w+4}{2}+\frac{1}{5}(5w-15)[/tex]
Then, do the same thing on the right. Distribute the fraction over the parenthesis again:
[tex]-\frac{7w+4}{2}+\frac{5w-15}{5}[/tex]
Here, on the right, 5 and 15 have a common factor of 5. Factor that out:
[tex]-\frac{7w+4}{2}+\frac{5(w-3)}{5}[/tex]
Finally, cancel out the 5s:
[tex]-\frac{7w+4}{2}+\frac{w-3}{1}\\\\-\frac{7w+4}{2}+w-3[/tex]
That's as simplified as it gets.
