So, adding two rationals is the same as adding two such fractions, which will result in another fraction of this same form since integers are closed under addition and multiplication. Thus, adding two rational numbers produces another rational number.

Answer:
1, yes it is a right angle. 2, yes it is a right angle.3, yes it is a right angle.
Step-by-step explanation:
1.Using the Pythagorean Theorem: 5 * 5 = 25, 12 * 12 = 144, 13 * 13 = 169, so 25 + 144 = 169 so yes it is a right angle.
2. Using the Pythagorean Theorem: 6 * 6 = 36, 8 * 8 = 64, 10 * 10 = 100, so 36 + 64 = 100, so yes it is a right angle.
3. Using the Pythagorean Theorem: 8 * 8 = 64, 15* 15 = 225, 17 * 17 = 289, so 64 + 225 = 289, so yes it is a right angle.

A car manufacturer is reducing the number of incidents with the transmission by issuing a voluntary recall. During week 3 of the recall, the manufacturer fixed 391 cars. In week 13, the manufacturer fixed 361 cars. Assume that the reduction in the number of cars each week is linear. Write an equation in function form to show the number of cars seen each week by the mechanic.
f(x) = 3x + 400
f(x) = 3x + 391
f(x) = −3x + 391
f(x) = −3x + 400
please explain ;-;
Answer:
f(x) = -3x + 400.
Step-by-step explanation:
To write the equation in function form to represent the number of cars seen each week by the mechanic, we need to consider the given information.
Let's define:
x: the number of weeks since the start of the recall.
Given that the reduction in the number of cars each week is linear, we can determine the equation by considering the initial number of cars fixed and the reduction rate.
In week 3, the manufacturer fixed 391 cars, which indicates that in the third week (x = 3), the number of cars fixed is 391. This gives us a reference point.
Now, we can find the equation in the form f(x) = mx + b, where m represents the slope (reduction rate) and b represents the initial value (number of cars fixed in the starting week).
To find the slope (m):
We need to determine the change in the number of cars fixed from week 3 (x = 3) to week 13 (x = 13).
The change in x is 13 - 3 = 10.
The change in the number of cars fixed is 361 - 391 = -30.
The slope (m) represents the rate of change, so we calculate it as:
m = (change in the number of cars fixed) / (change in x) = -30 / 10 = -3
Now, we have the slope (m = -3).
To find the initial value (b), we substitute the values of x and f(x) into the equation:
f(3) = 391
Plugging in the values:
-3(3) + b = 391
Simplifying the equation:
-9 + b = 391
Solving for b:
b = 391 + 9 = 400
Now, we have the slope (m = -3) and the initial value (b = 400).
Therefore, the equation representing the number of cars seen each week by the mechanic is:
f(x) = -3x + 400

television: $479, 40% markup
Mark Up: _______________
Answer:
Final price of $670.60, marked up by $191.60
Step-by-step explanation:
You multiply the original value of $479 with 0.4 (40%) to get 191.6. This is 40% of the television's value. Since you are adding 40% of the value to the original value, you add 191.6 with 479 to get $670.60.
Answer:
$191.6
Step-by-step explanation:
$ 479 multiplied by .40
=
$ 191.6

Can someone please explain what an exponent is? Apparently, I was supposed to learn what it was in Fifth grade but I didn't learn it at my od school. My friend says you are supposed to multiply it by itself the number of times the exponent is, for example, 2² you would multiply it by two twice. My other friends say you add it the number of time the exponent is.
Answer:
5² for example an exponent is the small number and depending on the number it multipies itself however many times for example 5² would be 5 * 5 and 7² would be 7 * 7 and vise versa
Step-by-step explanation:
Answer:
Exponent- [tex]5^{2}[/tex]
An expression that represents repeated multiplication of the same factor is called a power. The number 5 is called the base, and the number 2 is called the exponent. The exponent corresponds to the number of times the base is used as a factor.
i need help i cant figure this out-
Answer:
106.73 pi
Step-by-step explanation:
540 is the area of everything because 3 * 18 is 540.
The formula for the area of a circle is pi*(r^2)
The top ball has a diameter of 6 so we divide that by 2 to get the radius, 3. We can plug that in to get pi*3^2
We can simplify that to pi * 9
The next ball has a diameter of 9. Divide by 2 to get the radius, 4.5.
Plug that in to get pi * (4.5^2) simplified to be pi *20.25
The last circle has a diameter of 12 so therefore it has a radius of 6.
Plug that in and you get pi*(6^2). Simply that to get pi * 36
To find the area of all the balls we just need to add them. We get 55.25 * pi.
To subtract it they need to be either not in pi or both in pi. I will make them both not pi.
65.25 * pi = 204.885
I used 3.14 as pie.
To find the shaded area we need to subtract 204.885 from 540. When we do that we get 335.12.
We need to divide by pi now to get in terms of pi.
335.12 / 3.14 = 106.726115
You can round this to 106.73 You can round to any digit you want.
Joseph owns a dog that weighs 110 pounds. A bag of dog food recommends feeding a 40 pound dog 24 ounces of food per day. If x represents the amount of food needed to feed the larger dog, which proportion CANNOT be used to calculate how much food Joseph should feed his dog?
Answer:
the proportion which CAN be used is 1760/x = 640/24 THEREFORE ANY OTHER PROPORTION CANNOT BE USED
Step-by-step explanation:
J's dog= 110lbs =1760 ounces
food recommendation on bag: 40lbs:24 ounces, therefore in ounces 760 ounces (dog weight): 24 ounces (food)
J's dog required amount, 110:x which in ounces is 1760 ounces : x ounces
so we get:
1760/x = 640/24
take cross products,
4224= 640x
x= 66 ounces
the proportion which CAN be used is 1760/x = 640/24 THEREFORE ANY OTHER PROPORTION CANNOT BE USED

- 16 - x = 24
what is the X
Answer:
Hello!!! Princess Sakura here ^^
Step-by-step explanation:
First we have to add the 16 on both sides...
[tex]-16-x=24\\-x=40[/tex]
Now we are still not done we still have to divide -1 on both sides, we can't have a negative x...
[tex]x=-40[/tex]
So x equals -40.
