Answer:
Step-by-step explanation:
Apply the Pythagorean Theorrem. Find the sum of the squares of the two shortest sides and determine whether this sum equals the square of the longest side:
#19: 5^2 + 12^2 = ? = 13^2
25 + 144 = ? = 169 This is true, so you do have a right triange in #19.
#21: 2^2 + 4^2 = ? = 7^2, or 4 + 16 = ? = 49 This is false. Not a right
triangle.
Apply this same approach (Pythagorean Theorem) to the remaining problems.

Answer:
x=67°
Step-by-step explanation:
x and 113° make a straight angle or straight line, which is 180°, so
x+113°=180°
x=180°-113°=67°
The Answer Is M{x°}=67

In how many ways can 3 red balls , 4 blue balls and
5 white balls be selected from 5 red balls, 5 blue
balls and 7 white balls ?
Answer:
1050 ways
Step-by-step explanation:
Total Number of red balls = 5
Total Number of blue balls = 5
Total Number of white balls = 7
Number of red balls selected = 3
Number of blue balls selected = 4
Number of red balls selected = 5
Using the multiplication and combination relation :
nCr * nCr * nCr
Red balls = 5C3
Blue balls = 5C4
White balls = 7C5
Using calculator:
5C3 * 5C4 * 7C5 = 10 * 5 * 21
(10 * 5 * 21) = 1050 ways

Evaluate 3xy + b if x = -4 ,y = 2 , and b = 5
Answer:
-19
Step-by-step explanation:
ok so since they give you all the variables you can substitute their values
for example instead of 3xy you can write 3*(-4)y
so that is the basic idea for this problem
after substituting, the new equation is 3*(-4)*2 +5
i plan on using order of operations, or PEMDAS
3*(-4)=(-12)
(-12)*2=(-24)
-24+5=-19
so the answer is -19
hope this helps!

Answer:
g(x) = -x²
Step-by-step explanation:
By looking at the graph and equation of the blue quadratic line, you know the y-intercept is 4. When you look at the red one you can see the y-intercept is 0 so then the equation should be g(x) = -x²
Answer:
Answer B
Step-by-step explanation:
If both the function have the same shape, it means that the function f(x) is just shifted downwards to obtain function g(x).
The function f(x) is given as,
[tex]f(x) = 4 - x^{2}[/tex]
Shifting the curve downwards by 4 unites, the function g(x) is obtained,
[tex]g(x) = f(x) - 4\\g(x) = 4 -x^{2} - 4\\g(x) = -x^{2}[/tex]
I think option B is the correct choice.

A triangle has sides with lengths of 10 millimeters, 17 millimeters, and 18 millimeters. Is it a right triangle?
Answer:
no, it is not
if it were a right triangle, 10² + 17² = 18²
but this is not the case
Step-by-step explanation:
we would use Pythagoras theorem to determine if it is a right angle
The Pythagoras theorem : a² + b² = c²
where a = length
b = base
c = hypotenuse
10² + 17² =
100 + 289 = 389
square root of 389 is 19.72 and not 18. thus, it is not a right triangle

1. There is a 1/20 or 5% chance that the dart would land on section 20.
2. There is a 10/20 or 50% chance that the dart would land on an odd number.
There are 10 odd numbers present on the dart board.
3. 4/20 or 20%
There are 4 numbers greater than 16.
4. 0/20 or 0%
This is because there are no 25's on the dart board
5. 17/20 or 85%
This is because there are 17 numbers that aren't 4, 5, or 6.
6. 7/20 or 35%
There are 7 numbers less than 8.
7. 20/20 or 100% chance
8. 19/20 or 95% chance
I honestly was to lazy to right the rest in complete sentences, but i hope you find this well. Have a great day.

Which term can be used in the blank of 36x3−22x2−__ so the greatest common factor of the resulting polynomial is 2x? Select two options.
2
4xy
12x
24
44y
Given:
The expression is:
[tex]36x^3-22x^2-\_\_\_[/tex]
To find:
The values for the blank so that the greatest common factor of the resulting polynomial is [tex]2x[/tex].
Solution:
We have,
[tex]36x^3-22x^2-\_\_\_[/tex]
If the greatest common factor of the resulting polynomial is [tex]2x[/tex], then 2 and x must be factors of missing value.
In option A, 2 is a factor of 2 but [tex]x[/tex] is not a factor of 2. So, this option is incorrect.
In option B, 2 and [tex]x[/tex] are factors of [tex]4xy[/tex]. So, this option is correct.
In option C, 2 and [tex]x[/tex] are factors of [tex]12x[/tex]. So, this option is correct.
In option D, 2 is a factor of 24 but [tex]x[/tex] is not a factor of 24. So, this option is incorrect.
In option E, 2 is a factor of [tex]44y[/tex] but [tex]x[/tex] is not a factor of [tex]44y[/tex]. So, this option is incorrect.
It means the correct value for the given blank is either [tex]4xy[/tex] or [tex]12x[/tex].
Therefore, the correct options are B and C.

A family has two cars. The first car has a fuel efficiency of 20 miles per gallon of gas and the second has a fuel efficiency of 40 miles per gallon of gas. During one particular week, the two cars went a combined total of 1100 miles, for a total gas consumption of 35 gallons. How many gallons were consumed by each of the two cars that week?
Answer:
Car 1 consumed 15 gallons, and Car 2 consumed 20 gallons.
Step-by-step explanation:
fuel efficiency = distance in miles/gallons of gas
fuel efficiency * gallons of gas = distance in miles
Car 1: 20 mpg
Car 2: 40 mpg
Total miles: 1100
Miles of Car 1: x
Miles of Car 2: 1100 - x
Total gallons: 35
Gallons for Car 1: y
Gallons for Car 2: 35 - y
Car 1:
fuel efficiency * gallons of gas = distance in miles
20 * y = x
Car 2:
fuel efficiency * gallons of gas = distance in miles
40 * (35 - y) = 1100 - x
20y = x
1400 - 40y = 1100 - x
20y = x
x = 40y - 300
40y - 300 = 20y
20y = 300
y = 15
35 - y = 35 - 15 = 20
Car 1 consumed 15 gallons, and Car 2 consumed 20 gallons.

Can the sides of a triangle have sides of 5, 8, and 16 ???
Answer:
No.
Step-by-step explanation:
The triangle inequality theorem states that the sum of two sides of a triangle must be greater than the third side.
5 + 8 = 13.
13, which is the sum of two sides, is not larger than 16, the third side.
Therefore, a triangle cannot have these side lengths.
