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.
Hope this helps!

Answer:
x = 19
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.
x-coefficient: -1/3
inverse of x-coefficient = 1/(-1/3) = -3
Then you have ...

The diameters of two circles are 12 and 9 what the difference in square centimeters between the areas of the two circles
Step-by-step explanation:
Area of circle= π(d/2)²For 1st Circle, A1= 36π
For 2nd Circle, A2= 81π/4
A1-A2 = 63π/4
π = 22/7
=49.5unit²
The differences in the areas of circles in square centimeters is 49.455
Formula for area of circle
[tex]A = \pi r^{2}[/tex]
Where,
A is the area of circle
r is the radius of circle
and π = 3.14
What is radius of a circle ?Radius of circle is the distance from the center of the circle to any point on it's circumference. It is calculated as :
[tex]Radius = \frac{diameter}{2}[/tex]
According to the given question
Diameter of one circle is 12cm and diameter of another circle 9cm.
Area of circle with diameter 12 cm = [tex]\pi (\frac{12}{2} )^{2}[/tex] = [tex](3.14)(6)^{2}[/tex] = 113.04 square cm
Area of circle with diameter 9 cm = [tex]\pi( \frac{9}{2} )^{2} =(3.14)(4.5)^{2} = 63.585[/tex] square cm
Therefore,
The difference between the areas of two circles = (113.04 -63.585) square centimeter = 49.455 square centimeter.

4. sector angle = 120°
area of sector = 120/360* π*r^2
= 1/3 π *36 = 12π = 37.69 cm^2
area of isosceles ∆ = .5*36*sin 120 = 15.58cm^2
area of shaded portion = 37.69 - 15.58= 22.11 cm^2
5. sector area = 90/360 * π * 64 = 16π ft^2
area of right ∆ = 1/2*64= 32ft^2
shaded portion area = 16π-32 = 18.26ft^2
6. sector area = 60/360 π 36 = 6π m^2
triangle area = √3/4 * 36 = 9√3 m^2
shaded area = 18.84 - 9√3 = 3.26 m^2
7. sector area = 45/360*π*18^2 = 40.5 π yd^2
8. sector area = 90/360*π*16 = 64π cm^2
9. sector area = 60/360 * π * 169 = 28.16π m^2
10. sector area = 135/360*π*64 = 24π cm^2
1. circle area = π*5.5^2 = 30.25π cm^2
2. circle area = π*0.85*.85 = .7225π ft^2
3. circle area = π * 1/9 in^2
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
[tex] \therefore [/tex] The value of radius is 8 inches

1. The sum of Teresa's and Cathy's weight is
118 pounds. Teresa weighs 26 pounds more
than Cathy. If Teresa's weight is T and Cathy's
weight is C, which of these systems of
equations best represents this relationship?
A) T+C = 118
T= 26
B) T+C = 118
T +26=C
C) T+C=64
T-C= 26
D) T=C + 118
T=C+26
E) None of the above
Answer:
d
Step-by-step explanation:
E is ththe answer
the first equation should be T + C = 118 and the second equation should be C + 26 = T
none of these equations are correct

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°
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 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.
