Answer:
Gravity, also called gravitation, in mechanics, the universal force of attraction acting between all matter. ... On Earth all bodies have a weight, or downward force of gravity, proportional to their mass, which Earth's mass exerts on them. Gravity is measured by the acceleration that it gives to freely falling objects.

Answer:
a is greater than -2
Step-by-step explanation:
Solving a comparison like this is the same as solving an equation, except you need to watch out for the signs of numbers.
Given:
-2a - 12 < -8
The first thing we need to do here is to add 12 to both sides:
-2a - 12 + 12 < -8 + 12
-2a < 4
You'll notice we're just increasing both sides, so the relationship stays the same.
Now we divide both sides by -2. Because the number is negative, it changes whether the result is greater or less.
-2a < 4
-2a ÷ -2 > 4 ÷ -2
a > -2

The cash price of a bike is $3000. The bike can be bought on hire purchase by making a 25% down-payment and monthly payments of 125 for 2 years. The hire purchase is
A) $3000
B) $750
C) $ 3750
D) $125
Answer:
C) $3750
Step-by-step explanation:
We can start by calculating the down payment. To do this we can just simply calculate 25% of 3000, which equals 0.25*3000=7500. Now we can find out how much money it will cost to pay not including the down payment. $125 monthly for 2 years= $125 monthly for 24 months= 125*24= $3000. Finally we add the downpayment and the total cost of monthly payment to get $7500+$3000=$3750.

WWhat is the equation for the line of reflection? On a coordinate plane, triangle A B C has points (6, 3.7), (5.4, 2), (1, 3). Triangle A prime B prime C prime has points (3.7, 6), (2, 5.4), (3, 1). x = 3 y = 3 y = x x = 6
Answer:
[tex]y = x[/tex]
Step-by-step explanation:
Given
[tex]A =(6,3.7)[/tex]
[tex]B = (5.4,2)[/tex]
[tex]C = (1,3)[/tex]
[tex]A' = (3.7, 6)[/tex]
[tex]B' = (2, 5.4)[/tex]
[tex]C' = (3, 1)[/tex]
Required
The equation for the line of reflection
Taking points A and A' as a point of reference:
[tex]A =(6,3.7)[/tex] and [tex]A' = (3.7, 6)[/tex]
First, calculate the midpoint (M)
[tex]M = (\frac{x_2+x_1}{2},\frac{y_2+y_1}{2})[/tex]
[tex]M = (\frac{3.7+6}{2},\frac{6+3.7}{2})[/tex]
[tex]M = (\frac{9.7}{2},\frac{9.7}{2})[/tex]
[tex]M = (4.85, 4.85)[/tex]
Calculate the slope (m)
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{6 - 3.7}{3.7 - 6}[/tex]
[tex]m = \frac{2.3}{-2.3}[/tex]
[tex]m = -1[/tex]
The midpoint of a reflection is always perpendicular to the points being reflected.
So, the slope of [tex]M = (4.85, 4.85)[/tex] is:
[tex]m_2 = -\frac{1}{m}[/tex]
[tex]m_2 = -\frac{1}{-1}[/tex]
[tex]m_2 = 1[/tex]
The equation is then calculated as:
[tex]y = m_2(x - x_1) + y_1[/tex]
Where:
[tex](x_1,y_1) = (4.85,4.85)[/tex]
[tex]y = 1(x - 4.85) + 4.85[/tex]
[tex]y = x - 4.85 + 4.85[/tex]
[tex]y = x[/tex]
Hence, the equation of line of reflection is:
[tex]y = x[/tex]

Alexis had $25.00 to spend on amusement park she spent 25% of her money on games she spent 1/2 of her money on food she spent $6.00 on a stuffed animal. How much money did Alexis have left?
Answer:
Step-by-step explanation:
25% of $25 = 0.25×$25 = $6.25
½ of $25 = ½×$25 = $12.50
$25 - $6.25 - $12.50 - $6 = $0.25
convert the following repeating decimal to a fraction in simplest form .53
9514 1404 393
Answer:
53/99
Step-by-step explanation:
When an n-digit repeat begins at the decimal point, the repeating digits can be placed over an equal number of 9s to make a fraction. Sometimes, that fraction can be reduced to lower terms.
[tex]0.\overline{53}=\boxed{\dfrac{53}{99}}[/tex]
__
If the repeat does not start at the decimal point, the conversion can be done as follows.
For a number x with a decimal fraction that has n digits repeating, multiply by 10^n, subtract x and then divide by (10^n -1).
The fraction will be ...
(x·10^n -x)/(10^n -1) . . . where x has n repeating digits in the decimal fraction
Here, that looks like ...
[tex]x=0.\overline{53}\\100x=53.\overline{53}\\100x-x=53.\overline{53}-0.\overline{53}=53\\99x=53\\x=\dfrac{53}{99}[/tex]
. A fishing bobber has a radius of 0.5 inch. Find the volume of the fishing bobber. Round your answer to the nearest tenth.
Given:
The radius of the fishing bobber = 0.5 inch.
To find:
The volume of the find bobber.
Solution:
We know that the shape of fishing bobber is a sphere.
The volume of a sphere is:
[tex]V=\dfrac{4}{3}\pi r^3[/tex]
Substitute r=0.5 and [tex]\pi=3.14[/tex] to find the volume of the fishing bobber.
[tex]V=\dfrac{4}{3}(3.14)(0.5)^3[/tex]
[tex]V=\dfrac{4}{3}(3.14)(0.125)[/tex]
[tex]V=0.52333...[/tex]
Approx the value to the nearest tenth.
[tex]V\approx 0.5[/tex]
Therefore, the volume of the fishing bobber is 0.5 cubic inches.

Solve for the ? angle
Answer:
50
Step-by-step explanation:
since all angles add up to 180
and since this is a right triangle the square in the corner is 90 degrees
so 40+90+x=180
130+x=180
subtract 130 from both sides
130-130+x=180-130
x=50

What is mArc SU?
49°
77°
98°
161°
Answer:
77°
Step-by-step explanation:
By the property of intersecting tangent and secant outside of a circle:
[tex]21 \degree = \frac{1}{2} ( 119 \degree - \widehat{SU} ) \\ \\ 42 \degree = 119 \degree - \widehat{SU} \\ \\ \widehat{SU} =119 \degree - 42 \degree \\ \\ \widehat{SU} =77\degree \\ \\ [/tex]
The mArc SU is option (B) 77 degrees
What is Tangent?A straight line or plane that touches a curve or curved surface at a point, but if extended does not cross it at that point.
What is secant ?A secant is a line that intersects a circle in exactly two points.
Here,
By the property of intersecting tangent and secant outside of a circle:
[tex]T=\frac{1}{2}(RU-SU)[/tex]
Here
T= 21 degrees
RU is the mArc RU = 119 degrees
Then,
[tex]21 =\frac{1}{2}(119-SU)\\ 42=119-SU\\SU=119-42[/tex]
SU = 77 degrees
Hence, the mArc SU is option (B) 77 degrees
