Definition and description of gravity
Answer:
1. the force that attracts a body toward the center of the earth, or toward any other physical body having mass.
2. extreme or alarming importance; seriousness.
"crimes of the utmost gravity"
Step-by-step explanation:
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.

A piece of nickel has a mass of 3.48kg and a volume of 400cm3.
Answer:
density = 0.0087 kg/cm³
Step-by-step explanation:
density = mass/volume
= 3.48/400 = 0.0087 kg/cm³
Find the length of the hypotenuse if the base and height of a triangle are 6 m and 8 m , respectively
A. 28 M
B. 14 M
C. 10M
D.8 M
Answer:
Step-by-step explanation:
Use the Pythagorean Theorem.
base² + height² = hypotenuse²
6² + 8² = hypotenuse²
100 = hypotenuse²
hypotenuse = √100 = 10 meters
Which of the following equations is linear?
Answer:
D
Step-by-step explanation:
help with algebra please
Answer:
b = -0.79
Step-by-step explanation:
b+ 2.77 over -2 = -1.78
multiply -2 on both sides to get
b + 2.77 = -3.56
subtract 2.77 on both sides to get
b = -0.79

Find the inequality represented by the graph.
Answer:
y > 1/3 x - 3
Step-by-step explanation:
First, it would be easiest to find the equation of the line from the two integer points given, which are (0, -3) and (3, -2).
Find the change of y over the change of x to get the slope of the line.
(-2 - (-3))/(3 - 0) = 1/3
Since the line intercepts the y axis at (0, -3), the equation of the line would be
y = 1/3x - 3
We can see that the shaded portion is above the line, (and that the line is dotted) so this graph represents
y > 1/3 x - 3

feet per minute.
Bob's linear speed is higher than Jack's because the radius of the circle
around which Bob rotates is larger.
Responses:
Jack's linear speed is approximately 377 feet per minuteBob's linear speed is approximately 527.8 feet per minuteWhat is the relationship between linear speed and angular speed?Given:
The rotational speed of the merry go round = 6 revolution per minute
Jack's distance from the center = 10 feet
Bob's distance from the center = 14 feet
The angular speed, ω, of the merry-go-round is found as follows;
[tex]\omega = \mathbf{\dfrac{6 \times 2 \cdot \pi}{1 \ minute}} = 12 \cdot \pi \ rad/minute[/tex]Linear speed = ω × rWhich gives;
Jack's linear speed = 12·π rad/min × 10 feet ≈ 377 feet per minuteBob's linear speed = 12·π rad/min × 14 feet ≈ 527.8 feet per minuteLearn more about angular speed and linear speed here:

Write the equation of the line given the points (2,0) and (3.-1)
Answer:
y = -1x + 2
Step-by-step explanation:
We need to find y = mx + b
Use the following equation
[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Plug in the values
[tex]\frac{-1-0}{3-2}[/tex] = [tex]\frac{-1}{1} = -1[/tex]
We have found the slope(m) which is -1
We have to find y-int b
Plug in any given x,y into the slope formula
-1 = -1(3) + b
-1 = -3 + b
2 = b
At last the formula is
y = -1x + 2
(3, 2), y = 3x + 4 whats the answer
Answer:
[see below]
Step-by-step explanation:
Assuming that we need to see if the point is a solution:

The scale on a map is stated as
1:100 000
On the map, Jennifer estimates that the distance to her destination is 8 cm.
If she is correct in her estimate, how many kilometres is it to her destination?
9514 1404 393
Answer:
8 km
Step-by-step explanation:
The scale means the map distance of 8 cm translates to 800,000 cm in the real world. There are 100 cm in 1 m, and 1000 m in 1 km, so that distance is ...
800,000 cm = 8,000 m = 8 km
It is 8 km to Jennifer's destination.
the sum of two numbers is 103. If the greater number is divided by the smaller number the quotient is 2 and the remainder is 10 find the number
9514 1404 393
Answer:
31 and 72
Step-by-step explanation:
Let x be the smaller number and y be the larger number. Then we have ...
x + y = 103 . . . . . sum is 103
y = 2x +10 . . . . . y/x is 2 remainder 10
Substituting for y, we get ...
x + (2x +10) = 103
3x = 93
x = 31
y = 103 -31 = 72
The two numbers are 31 and 72.

12 is 30% of______________ pls help
Answer:
40
the
answer
is
40
Answer:
The 30% of a number can be calculated multiplying that number by 0.3, so, if we call the number we don't know x, we can write this equation:
0.3x = 12
And then solve it for x::
x = 12/0.3 = 40
So now we know that the number is 40.
We can replace the 40 in the equation to get if our answer is correct or not..
30% of 40: 0.3 * 40 = 12
And then, we see it's correct

If tan 2A = cot (A -18°), where 2A is an acute angle, find the value of A.
answer will be -24
A=-24
Answer:
A = 36
Step-by-step explanation:
Using the cofunction identity
tan(90 - x) = cotx
Given
tan2A = cot(A - 18) , then
90 - 2A = A - 18 ( add 2A to both sides )
90 = 3A - 18 ( add 18 to both sides )
108 = 3A ( divide both sides by 3 )
36 = A

Answer:
yearly cost for housing expenses = $11,400, average monthly cost for food = $650
yearly clothing cost = $900,
average monthly cost for transportation= $500,
Yearly cost for insurance & medical= $14,400
yearly cost for emergency fund = $600
average monthly college saving = $50
Step-by-step explanation:
Yearly housing = monthly cost * 12 = 950 * 12 = 11400
Food, monthly = 7800 /12 = 650
Clothing, yearly = 75 * 12 = $900
Monthly transport = 6000 / 12 = $500
Insurance and medical = 1200*12 =14400
Emergency fund = $50 * 12 = $600
College saving = $600 / 12 = $50
