does 13, 12, 6 form a pythagorean triple?
Answer:
No
Step-by-step explanation:
the pythagorean theorem is
a^2+b^2=c^2
These numbers do not fit in these terms
Answer:
It doesn't.
Step-by-step explanation:
In order for something to be a {ythagorean triple, it must comply with the Pythagorean theorem, which is a² + b² = c²
Always remember, when plugging in the values into that equation, the exponent of two means to square the number, and a and b have to be the two smallest values (in this case, 6 and 12)
6² = 36
12² = 144
36 + 144 = 180
Now, we have to find if ti equals c². 13² equals 169
Therefore, 180 ≠ 169, therefore it IS NOT a Pythagorean triple.

The radius of a circle is 13 feet. What is the circle's area?
Use 3.14 for pi.pleeeaaase heelpp!!
Answer:
answer is 530.66 hope this helps!
13×13=169
169×3.14=530.66
Answer:
I don't know if this is the answer but I got 530.66
Step-by-step explanation: the formula is A=pi r squared
you multiply 13 twice because in the formula you have to square the radius then you have to multiply what you get in this case 169 then you multiply it by pi which is 3.14 by 169 and you get 530.66 hopefully it is right let me know and if so brainliest please:)

How many males represented in the Venn diagram below have brown hair or brown eyes?
A diagram contains a rectangle labeled 100 males. The rectangle contains two overlapping ovals. The left oval is labeled brown hair 34, and the right oval is labeled brown eyes 22. The overlapping region is labeled 18. Both ovals are shaded.
74
22
56
34
Answer:
I got this answer right its 56
Step-by-step explanation:
I got this question right
Interpreting the Venn diagram given, the number of males with brown eyes or brown hair can be deduced to be 74
Number with brown hairs = 34 Number with brown eyes = 22Number with both brown hairs and eyes = 18Number with brown eyes or brown hairs :
Brown eyes + Brown hairs + Both brown hairs and brown eyes
(34 + 22 + 18) = 74
Therefore, 74 males have brown eyes or brown hairs

A sandbox in the shape of a trapezoid is show below. If a cover is to be made for the sandbox, what if the minimum amount of fabric needed?
The minimum amount of fabric needed for a sandbox is,
⇒ 72 feet²
We have to given that;
A sandbox in the shape of a trapezoid is show below.
And, a cover is to be made for the sandbox.
Hence,
The minimum amount of fabric needed for a sandbox is,
⇒ Area of fabric = 9 × 7 + (1/2 × 9 × 2)
= 63 + 9
= 72 feet²
Thus, The minimum amount of fabric needed for a sandbox is,
⇒ 72 feet²

How do I solve this?
-1/3+y=1
Answer:
y=-3
Step-by-step explanation:
.....................
Answer to equation:
y = 1 1/3
Step-by-step explanation:
for this problem we see that we are starting below 0 and going up to one, all we have to do is solve for the distance between the two numbers, as shown
(-1/3) + 1/3 = 0
0 + 1 = 1
now to simplify, we just add the total amount of change between the two numbers
1/3 + 1 = 1 1/3
NOTE: this can be done by just adding the absolute value of each number if one is a negative number and one is a positive number, wich is basically what i did
-1/3 = |1/3|
1 = |1|
|1/3| + |1| = |1 1/3| or total amount of change
but if you are working with two positive or two negative numbers, then subtract the lesser of the two absolute values as so
-2 + x = -5
-2 = |2|
-5 = |5|
|5| - |2| = |3|
3 = amount of change
3 = x
-2 + -3 = -5

Answer:
-26
Step-by-step explanation:
Hello There!
For this problem all we have to do is plug in -5 into x and calculate the value
so..
-3|-5|+2(-5)-1
so first things first | | means absolute value
The absolute values of -5 is 5 so the equation would be
-3(5) + 2(-5) - 1
-3*5=-15
2*-5=-10
-15-10=-25
-25-1=-26
so the answer would be -26

Last week, Russell bought 8 pizzas and 10 cakes for a total of $160.
Today, Russell bought 26 pizzas and 8 cakes for a total of $226.
Assuming neither item has changed in price, what is the cost of a pizza in dollars?
Answer:
$5
Step-by-step explanation:
Create a system of equations where p is the cost of a pizza and c is the cost of a cake
8p + 10c = 160
26p + 8c = 226
Solve by elimination by multiplying the top equation by -4, and the bottom equation by 5
-32p - 40c = -640
130p + 40c = 1130
Add these together:
98p = 490
p = 5
So, the cost of a pizza is $5

how do you solve fire x.
Answer:
x = 10
Step-by-step explanation:
Sum of all the angle of triangle = 180
71 + 50 + 6x - 1 = 180
71 + 50 -1 + 6x = 180
120 + 6x = 180
6x = 180 - 120
6x = 60
x = 60/6
x = 10
