How can you change grams into kilograms
Divide it by 1,000. One kilogram equals one thousand grams. This means that to get a pound of gram, you only have to divide the gram by 1,000.
A ball bearing has mass 0.44 pounds. 1 kg = 2.2 pounds.
Answer:
(i) 0.2 kg
(ii) kg/cm³
(b) 2.29 kg
Step-by-step explanation:
This problem gives you relations between units, and the formulas for density and mass. It is asking you to make use of these relations in various mass and density calculations.
(a)(i)The relationship between kg and pounds can be used to write a units conversion multiplier. It will have numerator equal to denominator, but will have units such that multiplying by it will give the units you want.
0.44 pounds × multiplier = __ kg
0.44 pounds × (1 kg)/(2.2 pounds) = (0.44/2.2)(1 kg)
0.44 pounds = 0.2 kg
__
(a)(ii)The formula can be used to find the units of interest:
Density = mass/volume
units of density = (units of mass)/(units of volume)
units of density = kg/cm³
__
(b)Using the given formula with the given value of L, we find the volume to be ...
V = 4(1.40 cm)(3 -1.40 cm)² = 14.336 cm³
Then the mass is ...
mass = volume × density
mass = (14.336 cm³)×(0.160 kg)/(1 cm³) = 2.29376 kg
The mass is about 2.29 kg.
_____
Additional comment
Often you will see density in terms of kg/m³ or g/cm³. Water has a density of about 1 g/cm³ or 1000 kg/m³. The most dense non-radioactive element in the periodic table is osmium, with a density of about 22.6 g/cm³, or 0.0226 kg/cm³. The material in part (b) of this problem has a density about 7 times that, so is clearly not from Earth.

How do you solve 162x0. 967 using standard algorithm?
Answer:
156.654
Step-by-step explanation:
The standard algorithm multiplies the integers as shown in the attachments, then places the decimal point in the result. Either factor can be used as multiplier or multiplicand.
For this problem, it might be easier to use 162 as the multiplier of 967, so the partial products are easier to form and check. This is shown in the second attachment. The first partial product is double the multiplicand; the second partial product is 3 times that value, and the third partial product is simply the multiplicand. In other words, you can choose the order of the numbers so as to make the effort easier.
The result is the sum of the partial products, with three decimal places: 156.654.

Additional comment
One must be careful with the decimal point when the numbers contain factors of 2 and 5. The trailing zeros must be maintained until the decimal point is placed. For example, 0.25 × 0.4 = 0.100. The trailing zeros count in the total of 2+1=3 decimal places.
The perimeter of a rectangle is 116. The length is 18 more than 3 times the width. Fine the dimensions
Answer:
L = length, W = width and P = perimeter
L = 3W + 18
Perimeter = 116 = 2(L + W) , i.e. L + W = 58
Now substitute
3W + 18 + W = 58
4W = 40
W = 10
L = 48
Step-by-step explanation:
If the perimeter of a rectangle is 116. The length is 18 more than 3 times the width. The length and width of the rectangle will be 48 and 10 units.
What is a rectangle?It is defined as two-dimensional geometry in which the angle between the adjacent sides is 90 degrees. It is a type of quadrilateral. The area occupied by the rectangle in two-dimensional planner geometry.
The area of a rectangle can be calculated using the following formula:
Rectangle area = length x width
It is given that, the perimeter of a rectangle is 116. The length is 18 more than 3 times the width. Fine the dimensions
L = length, W = width and P = perimeter
L = 3W + 18 -------- (1)
Perimeter = 116
Perimeter = 2(L + W)
L + W = 58
Put the value in equation 1,
3W + 18 + W = 58
4W = 40
W = 10
L = 48
Thus, if the perimeter of a rectangle is 116. The length is 18 more than 3 times the width. The length and width of the rectangle will be 48 and 10 units.

Find the area and perimeter of the trapezoid. See picture for full problem. Please and thank you so very much!
Answer:
The area of the trapezoid is 22.5 square miles.
The perimeter of the trapezoid is 22.5 miles.
Step-by-step explanation:
Recall that the area of a trapezoid is given by:
[tex]\displaystyle A = \frac{1}{2}(b_1+b_2)h[/tex]
Where b₁ and b₂ are the two parallel bases and h is the vertical height between them.
The two bases are 5.5 mi and 3.5 mi and the vertical height between them is 5 mi. Hence, the area of the trapezoid is:
[tex]\displaystyle \begin{aligned} A & = \frac{1}{2}(5.5+3.5)(5) \\ \\ & = \frac{1}{2}(9)(5) \\ \\ & = \frac{45}{2} \\ \\ &= 22.5\text{ mi}^2\end{aligned}[/tex]
The perimeter of the trapezoid is simply the sum its four sides. Hence:
[tex]\displaystyle \begin{aligned} P & = (5.5) + (6) + (7.5) + (3.5) \\ \\ & = 22.5\text{ mi} \end{aligned}[/tex]
Therefore, the area and perimeter of the trapezoid is 22.5 square miles and 22.5 miles, respectively.

I need help finding the domain and range!! -Algebra
Answer:
The graph is shown belowVertex = (2,1)Axis of symmetry is x = 2Domain = set of all real numbersRange = set of y values such that [tex]y \ge 1[/tex]=======================================================
Explanation:
Use your favorite graphing tool to graph the equation. If your teacher doesn't allow you to use graphing software, then you'll have to plug in various x values to find the paired y values. This gives the set of (x,y) points needed to be plotted to form the parabola. The more points you plot, the more accurate the curve.
The graph is shown below. I used GeoGebra to make the graph. It's free graphing software. Desmos is another tool that I recommend.
------------
The lowest point on the parabola is the vertex (h,k) = (2,1) which is shown in the graph below.
This is due to the equation being in vertex form y = a(x-h)^2 + k. We see that h = 2 and k = 1.
-------------
The axis of symmetry is the vertical line that passes through the vertex.
As such, the axis of symmetry equation is simply x = h. So that's how we get to x = 2.
In the graph below, the axis of symmetry is the red dashed line.
-------------
There aren't any restrictions on x. We don't have to worry about dividing by zero or applying a square root to a negative number.
Therefore, any x value is allowed and the domain is the set of all real numbers.
-------------
The range however isn't the set of all real numbers. The lowest y can get is y = 1 due to the vertex point. We can have y = 1 or larger
Therefore, [tex]y \ge 1[/tex] is the range.

Dilate ABC below using A as the center and a
scale factor of 2. Leave all construction marks?
Explanation:
Use your straightedge to extend segment AB into ray AB. This means you'll have it start at A and go on forever through B. Repeat these steps to turn segment AC into ray AC.
The two rays join at the vertex angle A. Point A is the center of the universe so to speak because it's the center of dilation. We consider it an invariant point that doesn't move. Everything else will move. In this case, everything will move twice as much compared to as before.
Use your compass to measure the width of AB. We don't need the actual number. We just need the compass to be as wide from A to B. Keep your compass at this width and move the non-pencil part to point B. Then mark a small arc along ray AB. What we've just done is constructed a congruent copy of segment AB. In other words, we've just double AB into AB'. This means the arc marking places point B' as the diagram indicates.
The same set of steps will have us construct point C' as well. AC doubles to AC'
Once we determine the locations of B' and C', we can then form triangle A'B'C' which is an enlarged copy of triangle ABC. Each side of the larger triangle has side lengths twice as long.
Note: Points A and A' occupy the same exact location. As mentioned earlier, point A doesn't move.

You have 2 bags, bag 1 had 5 green marbles, 6 red marbles, 7 pink
marbles and 3 yellow marbles. bag 2 had 6 green marbles 2 red marbles 3 pink marbles and 8 yellow marbles if you pull one from each what is the probability of getting a pink marble from each bag?
Answer:
The answer is 4/10
Step-by-step explanation:
If you add all marbles in both bags it equals 40. There are 10 pink marbles in both so 40 / 10 is 4 and the denominator would be 10. 4/10
Answer:
The odds of getting a pink marble from the 1st bag are 7/21, .333 repeating, or approximately 33%.
The odds of getting a pink marble from the 2nd bag are 3/19, .158, or approximately 16%
Step-by-step explanation:
There are a total of 21 marbles in the first bag, and only 7 pink marbles. This means that when you reach into the bag, your odds are 7 out of 21 to select a pink marble. When divided, this can be changed to a percent or decimal.
There are a total of 19 marbles in the second bag, and only 3 pink marbles. When you reach into this bag, your odds are 3 out of 19 to select a pink marble. You can also divide this to become a percent or decimal.
Probability is often calculated in fraction or decimal form. If I flip a coin the odds of getting tails are 50% percent because there are only two possible outcomes, and tails is one of them. This gives you the fraction 1/2 (one-half), which is 50% when reduced.
