Slope Formula[tex]\cfrac{y2-y1}{x2-x1}[/tex]
Y2 and Y1 represent the y-coordinates, and X2 and X1 represent the x-coordinates.
We are given the points:
(4, 6) and (7, 12)
Using this formula, we plug in the given points like so:
[tex]\cfrac{12-6}{7-4}[/tex]
Now we can simplify:
[tex]\cfrac{12-6}{7-4}=\cfrac{6}{3} =2[/tex]

To answer wait you put into the big, it would be .28 since when making a percentage a decimal you move the decimal point to the left twice. There is always an invisible decimal after a whole number (ex. 28.0). And to find out what 28% of 140 is you simply do .28 x 140 to find that, which is 39.2.

Angles and Parallel Lines
Answer:
a = 6
b = 25
Step-by-step explanation:
As alternative angles in a parallel line are equal to each other,
5a = 3a + 12
So, now we can find the value of a by making "a" the subject.
5a - 3a = 12
2a = 12
Divide both sides by 2.
a = 6°
And now let us find the value of b.
We know that interior angles in a triangle are added up to 180°.
So,
2b + 4b + 3a + 12 = 180
We can replace a with 6 and then we can make "b" the subject to find the value of b.
Let us solve it now.
2b + 4b + 3 × 6 + 12 = 180
6b + 18 + 12 = 180
6b + 30 = 180
6b = 180 - 30
6b = 150
Divide both sides by 6.
b = 25°

A cylinder has a height of 15 inches. Its volume is 3,014.4 cubic inches. What is the radius of the cylinder?
Use ≈ 3.14 and round your answer to the nearest hundredth
Answer:
Radius = 8in
Step-by-step explanation:
[tex] \hookrightarrow \sf \: V = {\pi r}^{2} h[/tex]
Where,
v = 3014.4h = 15π = 3.14⇢ 3014.4 = (3.14)(r²)(15)
⇢ 3014.4 = (r²)(47.1)
⇢ 3014.4 = 47.1r²
⇢ 3014.4/47.1 = 47.1r²/47.1
⇢ 64 = r²
⇢ r = √64
⇢ r = 8

Step-by-step explanation:
The work shown is almost complete. It can be finished by multiplying both sides of the equation by the inverse of the coefficient of x.

Does the point make the equation true ?
Answer:
(3, 4) does not make y = .5x + 1.5 true.
Step-by-step explanation:
y = .5x + 1.5
(3, 4)
Substitute 3 for x and 4 for y and see if the two sides of the equation are equal to each other.
4 = .5(3) + 1.54 = 1.5 + 1.54 = 3Since 4 ≠ 3, the point (3, 4) does not make the equation y = .5x + 1.5 true.

what is equivalent to sin10cos25-cos10sin25
Answer:
- 0.2588
Step-by-step explanation:
Theory: sin(a - b) = sin(a)*cos(b) - cos(a)*sin(b)
In this case a stands for 10 AND b stands for 25
Hence:
sin10cos25-cos10sin25 = sin (10 - 25) = sin (-15) = - sin(15) = - 0.2588

What fraction shows what each person gets if 9 friends share 5 apples?
Answer: 5/9 of an apple
Step-by-step explanation:
Since there are more people than apples, you know that the aples are going to be cut and every person will get less than one apple. You just divide the 5 apples to the 9 people. The simple way is putting the numbers and making it a fraction. In this case, 5/9. 5 apples as the numerator and 9 people as the demoninator.
