Answer:
thanks
Step-by-step explanation:
We can prove this by contradiction.
Let us assume that c2=a2+b2 in ΔABC and the triangle is not a right triangle.
Now consider another triangle ΔPQR. We construct ΔPQR so that PR=a, QR=b and ∠R is a right angle.
By the Pythagorean Theorem, (PQ)2=a2+b2.
But we know that a2+b2=c2 and a2+b2=c2 and c=AB.
So, (PQ)2=a2+b2=(AB)2.
That is, (PQ)2=(AB)2.
Since PQ and AB are lengths of sides, we can take positive square roots.
PQ=AB
That is, all the three sides of ΔPQR are congruent to the three sides of ΔABC. So, the two triangles are congruent by the Side-Side-Side Congruence Property.
Since ΔABC is congruent to ΔPQR and ΔPQR is a right triangle, ΔABC must also be a right triangle.
This is a contradiction. Therefore, our assumption must be wrong.

You invested $7000 in two accounts paying 7% and 8% annual interest, respectively. If the total interest earned for the year was $536, how much was invested at each rate?
Answer: $4,600 was invested in the 8% account and $2,400 was invested in the 7% account.
Step-by-step explanation:
Let's break this down into simpler terms so you can understand.
You invested $7000 in a 7% and 8% account (always remember: the 'x' variable is always given to the biggest percentage)
Total of interest: 536 (this always goes at the end of the equation, after the equal sign)
Step 1: Let's set up the equation:
Here are how percents are written: (7% = 0.07, 8% = 0.08, other examples: 50% = 0.50)
0.08x + 0.07(7,000-x)=536
You're adding both because you want to see how much each account paid together.
Step 2: Distribute the 0.07 to everything in the parenthesis
0.08x + 0.07(7,000-x)=536
0.08x + 490 - 0.07x =536
Step 3: Combine like terms
0.08x + 490 - 0.07x =536
0.01x + 490 =536
Step 4: Continue combining like terms
0.01x + 490 =536
0.01x = 46
Step 5: Divide both sides by 0.01 to get the 'x' by itself
0.01x = 46
x = 4,600
This answer, x = 4,600, says to us that $4,600 was invested in the 8% account.
To find out how much was invested in the 7% account, just replace the x = 4,600 back into this part of the original equation: 7,000-x
7,000-x
7,000-4,600
2,400
So.. $4,600 was invested in the 8% account and $2,400 was invested in the 7% account.
10 % of what number is 29?
Answer:
290
Step-by-step explanation:
To solve this problem you multiply 29 by 100 and then divide the total by 10 as follows:
(29 x 100) / 10
Therefore, you can derive that 10 percent of 290 equals 29.
Note that the answer provided is rounded to the nearest two decimals if necessary.
Write 2.71x10-3 as an ordinary number.
Step-by-step explanation:
[tex] {2.71 \times 10}^{ - 3} [/tex]
This can be rewritten as
[tex]2.71 \times \frac{1}{10^{3} } [/tex]
If we will solve this way,
[tex]\frac{2.71}{1000} = 0.00271[/tex]
But since the denominator is just in terms of 1, we can just simply get the (-3). Note that we have to take the negative into consideration.
From the original position of the decimal point, move the decimal point 3 times TO THE LEFT. Therefore, from 2.71 we move the decimal point 3 times to the left, 0.00271.
If the exponent has a positive value, move TO THE RIGHT.
For example,
[tex]2.71 \times {10}^{3} = 2.71 \times 1000 \\ = 2710[/tex]
Note that the exponent has a positive value. Therefore, we have to move the decimal point 3 times TO THE RIGHT. Producing 2710 as the answer.

If I have a ratio 2:6, then what is x/18?
f I have a ratio 5:7, then what is (x+3):7?
Answer:
1. x=6
2. x=2
Step-by-step explanation:
2:6
x:18
From 6 to 18, 6 was multiplied by 3. To keep the equality, we must multiply the other side by three as well. Therefore, x is equal to 2*3 which equals 6.
x=6.
5:7
(x+3):7
For this one, the second value did not change, so we know that x+3 has to equal 5. Therefore, x=2.
x=2

a taxi charges $2 per mile and $1 per person. If a ride for 2 people costs $12, how many miles was the ride?
Answer:
5 miles
Step-by-step explanation:
$12 = ($2 per mile) (2 people)
$12 = $2 + $2m (m = mile)
subtract 2 on both sides to eliminate
$12 - $2 = $2 - $2 + 2m
$10 = 2m
divide both sides by 2 to eleminate m
$10 / 2 = 2m / 2
m = 5

The cost of making copies at Store W is $6 regardless of the number of copies. The cost of making copies at Store Z is 50¢ per copy plus a $1 charge for the use of the machine. The total cost, c, of making n copies at either store can be represented by an equation. Write and graph a system to find how many copies you have to make for the cost to be the same at both stores. Use pencil and paper. If you have to make a small number of copies which store should you go to? If you have to make a large number of copies which store should you go to? Explain.

Rhombus
b= 14 in.
h=9 in.
Paralelogram
b= 12ft
h= 8.5ft
A rhombus has an area of 375 mm2 and a base of 25 mm. What is its height?
Answer:
Step-by-step explanation:
The solution is, The area of Rhombus B is 9 times bigger than the area of Rhombus A. The reason is that 2 dimensions were tripled, so x3 x3 = 9 times bigger.
What is area ?Area is the measure of a region's size on a surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of a three-dimensional object.
here, we have,
Rhombus A:
Area = 35 square inches
base = 7 inches
height = 5 inches
Rhombus B:
Area = 315 square inches
base = 21 inches (7 x 3)
height = 15 inches (5 x 3)
A = 21 x 15
so, we get,
The area of Rhombus B is 9 times bigger than the area of Rhombus A. The reason is that 2 dimensions were tripled, so x3 x3 = 9 times bigger.

Use the Distributive Property to simplify the expression.
15 (4n-2)
Answer:
distributive property solve 3 into 4 - 2
Hello!
The Distributive Property states the following:
a(b+c)=ab+ac
where
a, b, and c can be either constants or variables.
Now, simplify:
15(4n-2)
15*4n - 15*2
60n-30
And we can't simplify it any further, because 60 n and 30 aren't like terms.
Hope everything is clear.

d. W(12) = W(10)
e. W(15) > W(30)
f. W(0)
Answer:
Initial temperature, temperature at time 0
Step-by-step explanation:
The temperature of water in degree Fahrenheit 1 minute after stove is turned on ;
W(0) = 72 ; Initial temperature od water, that is temperature when time, t = 0
W(5) > W(2) ; This will be true, the tperature after 5 minutes should be greater Than the temperature after 2 minutes
W(10) = 212 ; The temperature of water is 212 degree Fahrenheit after 10 minutes
W(12) = W(10)
e. W(15) > W(30)

true or false please help thank you
Answer:
True.
See below for explanation.
Step-by-step explanation:
Reason 1
When we solve the equation by combining both equations in one, the variable will become 0.Proof
[tex] \begin{cases} y = 4x - 3 \\ y = 4x - 5 \end{cases} \\ 4x - 3 = 4x - 5 [/tex]
Combine like terms.
[tex]4x - 4x = - 5 + 3 \\ 0 = - 2[/tex]
See that the equation is false no matter which numbers you substitute in x-term.
Reason 2
Both graphs are parallel and don't have any intercepts to each others.See the attachment below for graphs.
Since both graphs do not really have intercepts, that means they do not provide any solutions. Hence, no solutions.
