Answer:
Step-by-step explanation:
Because angles A and B are the same, line segments AB and BC are the same. This means you can use the same variable for both in the Pythagorean theorem.
x²+x²=20²
2x²=400
x²=200
x=√200
x=14.1421356237
Answer:
x = 10[tex]\sqrt{2}[/tex]
Step-by-step explanation:
this is a 45-45-90° Δ and the leg to hypotenuse ratio is always 1 : [tex]\sqrt{2}[/tex]
so we can set up a proportion:
20 / [tex]\sqrt{2}[/tex] = x / 1
cross-multiply:
[tex]\sqrt{2}[/tex]x = 20
x = 20 / [tex]\sqrt{2}[/tex], which simplifies to 10[tex]\sqrt{2}[/tex] if you rationalize the denominator

What number do you multiply to find this partial product 8×56
Answers
Answer: 8*56 is 448
you could also multiply 2⁶ x 7 to get 448
The number that you can multiply to find this partial product 8×56 is 8 and (50+6).
What is the partial product?The partial product method involves multiplying each digit of one integer by each digit of another, while each digit retains its position. For example, 23 x 42 becomes (20 x 40) + (20 x 2) + (3 x 40) + (3 x 2).
The number that you can multiply to find this partial product is,
8×(50+6)
= (8×50) + (8×6)
= 400 + 48
= 448
Hence, the number that you can multiply to find this partial product 8×56 is 8 and (50+6).

A table is 2 feet wide it is 6 times as long it is wide
Answers
Answer:
Length = 12 feet
Perimeter = 28 feet
Area = 24ft²
Step-by-step explanation:
You didn't ask a question so I don't know what the answer you want is so I assumed it was related to one of the answers shown above.
To calculate the length, you simply do 6*2
which is equal to 12.
The length is 12 feet.
However, if you want to find the perimeter:
12 + 12 + 2+ 2 = 28ft
If you wanted to find the area:
12*2 = 24ft²
I hope this helps!
For positive integer n, the factorial notation n! represents the product of the integers from n to 1. (For example, 6! = 6*5*4*3*2*1.) What value of n satisfies the following equation?
5! X 9! = 12! x N
Answers
Answer:
The value of N that satisfies the equation is [tex]\frac{1}{11}[/tex]
Step-by-step explanation:
First we open the factorial of 12, to simplify the expression:
12! = 12*11*10*9!
So
5!*9! = 12!*N
5!*9! = 12*11*10*9!N
12*11*10N = 5!
Now we open the factorial of 5. So
12*11*10*N = 5*4*3*2*1
Since 5*2 = 10, 4*3 = 12, we have that:
12*11*10*N = 10*12*1
Now, simplifying by 10*12
11N = 1
[tex]N = \frac{1}{11}[/tex]
This is the value of N that satisfies the equation

Hence statement 3 and 5 are true from the equation given in question.
What is equation?The definition of an equation in algebra is a mathematical statement that proves two mathematical expressions are equal.
Types of Equations:
Linear Equation: More than one variable may be present in a linear equation. An equation is said to be linear if the maximum power of the variable is consistently 1.
Quadratic Equation: This equation is of second order. At least one of the variables in a quadratic equation needs to be raised to exponent 2.
Cubic Equation: A third-order equation is this one. At least one of the variables in cubic equations needs to be raised to exponent 3.
Rational Equation: A fractional equation having a variable in the numerator, denominator, or both is referred to as a rational equation.
Number of cans used 1/10 part of room = 1/2
No. of cans paints used 1 part = 1/2 / 1/10 = 5
∵ 1/2 can paint is used = 1/10
∴ 1 can paint used = (1/10)*2 = 1/5
∴ 5 cans = 100%
3 cans used = (3/5)*100 = 60%

The area of the triangle formed by points of intersection of parabola y=a(x−3)(x+2) with the coordinate axes is 10. Find a if it is known that parabola opens upward.
Answers
Answer: a = 4
Step-by-step explanation: Area of a triangle is calculated as: [tex]A_{t}=\frac{b.h}{2}[/tex].
The triangle formed by the parabola has base (b) equal to the distance between the points where the graph touches x-axis and height (h) is the point where graph touches the y-axis.
The points on the x-axis are the roots of the quadratic equation:
a(x-3)(x+2)=0
(x-3)(x+2)=0
x - 3 = 0
x = 3
or
x + 2 = 0
x = -2
So, base is the distance between (-2,0) and (3,0).
Since they are in the same coordinate, distance will be:
b = 3 - (-2)
b = 5
Area of the triangle is 10. So constant a is
[tex]10=\frac{5.a}{2}[/tex]
5a = 10.2
a = 4
The constant a of the function y = a(x-3)(x+2) is 4.
Answer: a = 2/3
Step-by-step explanation:
y-intercept: y=a(2)(-3) = -6a
x-intercepts: (-2,0) , (3,0)
height = -6a
base = 5
Area = 10 = 0.5 x 5 x -6a
10 = -15 a
a = -2/3
BUT a>0 since it opens upwards, so:
a = 2/3
