6. What percent of 24 is 12?
Answer plsss
Answer:
50%
Step-by-step explanation:
To find our answer will will first put it into an equation as [tex]\frac{100}{x}[/tex] × [tex]\frac{24}{12}[/tex]. Because we are cross multiplying we will multiply 100 by 12 and we get 1,200. Now because we are solving for x we will divide 1,200 by 24, which is 50%. Therefore, 50% is our answer.

The quadratic regression equation that fits these data is -1.107 X² +3.736 X +10.643 .
What is Quadratic Regression ?A quadratic regression is the process of finding the equation of the parabola that best fits a set of data. As a result, we get an equation of the form:
y=ax2+bx+c where a≠0 .
The best way to find this equation manually is by using the least squares method.
That is, we need to find the values of a ,b, and c such that the squared vertical distance between each point (xi,yi) and the quadratic curve y=ax2+bx+c is minimal.
After solving we get the values of a , b, and c and thus we form the equation
-1.107 X² +3.736 X +10.643

Answer:
y=7x
Step-by-step explanation:
Take two points from the line and plug them into y2-y1/x2-x1. In this case, I chose (6,42) and (7,49). This will make the equation 49-42/7-6. This is equal to 7/1 or 7. Therefore, the equation is equal to y=7x.

What two numbers multiply into (-24) and adds up to (-11)?
Answer:
-3 and -8
Step-by-step explanation:
Let the two numbers be called a and b respectively. We can say that ab=-24, and a+b=-11.
If a+b=-11, a=-11-b.
ab=-24
(-11-b)b=-24
b²+11b+24=0
(b+3)(b+8)=0
b=-3, b=-8
a=-11-b=-11+3=-8
a=-11-b=-11+8=-3
So the numbers are -3 and -8

The expanded form of 3(4a) is:
Answer:
12a
Step-by-step explanation:
Use the distributive property and distribute 3 into 4a.
The expanded form of the expression 3(4a) is, 12a.
What are the basic properties of arithmetic laws of operations?There are three types of basic arithmetic laws of operation.
Commutative law for addition and multiplication states,
a + b = b + a.
a×b = b×a.
Distributive law states,
a(b ± c) = ab ± ac.
Associative law states,
a + (b + c) = (a + b) + c.
Given, An expression 3(4a),
We know in algebra we write multiplications a×b as, ab or a.b.
Therefore, the expanded form of the expression 3(4a) is,
= 3×4×a.
= 12×a.
= 12a.

The measure of an angle is twenty-three times the measure of its supplementary angle. What is the measure of each angle?
Answer:
∡'s are 172.5° and 7.5°
Step-by-step explanation:
x = 23(180-x)
x = 4140 - 23x
add 23x to each side
24x = 4140
x = 4140/24
x = 172.5
So, supplementary angles is an angle pair that adds up to 180 degrees.
If one of the angles is 23 times larger than the other angle, then the other angle would be 1 times larger, due to the reflexive prop.
So combined, the angle pair is 24 times larger than the small angle. And since we know that the supplementary angle is 180, it's something that easy math can solve.
For the small angle:
180 / 24 --> 7.5 degrees.
Now with the big angle that 23 times that:
7.5 * 23 --> 172.5 degrees.
The area of the triangle shown is represented by A=s(s−14)(s−12)(s−6)−−−−−−−−−−−−−−−−−−−−√A=s(s−14)(s−12)(s−6), where s is equal to half the perimeter. What is the height h of the triangle? Round your answer to the nearest hundredth.
Answer:
[tex]h=5.11ft[/tex]
Step-by-step explanation:
[tex]S=12+6+14/2=16[/tex]
[tex]area ~A= \sqrt{s(s-14)(5-12)(5-6)}[/tex]
[tex]area=\sqrt{16(16-14)(16-12)(16-6)}[/tex]

Find the surface area of the prism. The surface area is
Answer:
132m^2
Step-by-step explanation:
Area=10x5+3x4x2/2+10x3+4x10
=50+12+30+40
=132
Answer: 132 meters squared
Step-by-step explanation:
We add all the sides of the shape:
Three quadrangular sides:
3 x 10 = 30
4 x 10 = 40
5 x 10 = 50
30 + 40 + 50 = 120
Two triangular sides:
3 x 4 / 2 = 6
3 x 4 / 2 = 6
6 + 6 = 12
We add all up:
120 + 12 = 132 meters squared
