If 1 gram = 100 centigrams and 1 centigram = 10 milligrams, how many
milligrams are in 1.42 grams?
0.142
142
1,420
14,200
Answer:
1,420 milligrams
Step-by-step explanation:
We know there are 100 centigrams in 1 gram, and there are 10 milligrams in a centigrams. That would mean there are 1,000 milligrams in 1 gram (100 * 10 = 1000).
As a result, all you need to do is multiply 1.42 by 1000 to get the amount of milligrams.
1.42 * 1000
Alternatively, to make 1.42 a whole number first, multiply by 100, then add a zero. (That's the other 10!)
(1.42 * 100) * 10
142 * 10
There are 1,420 milligrams in 1.42 grams.

A pigeon flies for 7 hours at a speed of 70 km/h.
Calculate how far the pigeon flies.
Answer:
490km
Step-by-step explanation:
70km/hrs for 7hrs
so if the pigeon flies 70km in one hour we just have to multiply 70 by 7 to get 7hours.
70x7=490km
That means the pigeon flies 490km in 7hrs

Pls help.... i dont really know how to find this slope ;/
Answer:
a
Step-by-step explanation:
the answer is a because every week it shows (shows on the graph) that he is earning 6 dollars.
Answer:
A
Step-by-step explanation:
The formula for slope is [ y2-y1/x2-x1 ] and we can use the points (0, 0) and (5, 30) to solve.
30-0/5-0
30/5
6/1
6
Now that we know what the slope is, we can eliminate C and D.
This means that he saves around $6 per week. With this being said, we can eliminate B as well.
Best of Luck!

students are girls?
Answer: 16 of the students are girls.
Step-by-step explanation:
3/5 = boys —> 60% of students.
2/5 = girls —> 40% of students.
40% = 0.4
G = 40 * 0.4
G = 16

Answer:
X= 43/3
Step-by-step explanation:
-1/4 x 5 = 3/4x - 12
-5/4=3/4x -12
-5=3x - 48
-3x-5 = -48
-3x = -48 + 5
-3x= -43
-3 x= -43
X= 43/3
A group of people were asked if they had run a red light in the last year. 290 responded "yes", and 177 responded "no". Find the probability that if a person is chosen at random, they have run a red light in the last year.
Answer:
0.621
Step-by-step explanation:
Number of people that have run a red light in the last year = 290
Number of people that have not run a red light in the last year = 177
Total number of respondents = 290 + 177
= 467
Pr(if a person is chosen at random, they have run a red light in the last year) = [tex]\frac{number of people who has run the red light last year}{total number of respondents}[/tex]
= [tex]\frac{290}{467}[/tex]
= 0.621
The probability that if a person is chosen at random, they have run a red light in the last year is 0.621.
Find the volume of each figure. Round your answers to the nearest hundredth, if necessary. Leave your answers in terms of pi for answers that contain pi.
Answer:
125πkm
Step-by-step explanation:
The figure shown is a cylinder :
Volume of a cylinder is obtained using tbe relation :
V = πr²h
Where ; r = Radius ; h = height
r = 5km ; height = 5km
Hence,
V = π * 5² * 5
V = 25 * 5 * π
V = 125πkm

State if each set of three numbers can be the lengths of the sides of a triangle.
Step-by-step explanation:
Imagine lying out 2 sticks with lengths 9 and 12
on the ground. The maximum length you can
get is by putting them in a straight line. (9 + 12 = 21)
However, 21 is less than 24, which is
supposed to be the 3rd side of the triangle.
Hence the set 9, 12, 24 cannot form a triangle.

the center of a circle is 5 units below the origin, and the radius is 10 units. what is the equation of the circle?
x^2+(y+5)=10
(x+5)^2+y^2=10
x^2 + (y+5)^2=100
(x+5)^2+y^2=100
Answer:
x² + (y + 5)² = 100
Step-by-step explanation:
If the center of the circle is 5 units below the origin, its x coordinate is 0 and its y-coordinate is -5. So, the center of the circle is at (0, -5).
Using the equation of a circle with center (h, k)
(x - h)² + (y - k)² = r² where r = radius of the circle.
Given that r = 10 units, and substituting the values of the other variables into the equation, we have
(x - h)² + (y - k)² = r²
(x - 0)² + (y - (-5))² = 10²
x² + (y + 5)² = 100
which is the equation of the circle.
Answer:(c)
Step-by-step explanation:
Given
the radius of circle=10 units
The center is 5 units below the origin i.e. (0,-5) is the center
The general equation of a circle is
[tex](x-a)^2+(y-b)^2=r^2\quad [\text{Where, (a,b) is the center of the circle and r is radius}][/tex]
Putting values
[tex](x-0)^2+(y-(-5))^2=10^2\\(x)^2+(y+5)^2=100[/tex]
Second last option is correct

The area of a rectangle is expressed as (12m + 18). If the width is 6, factor a 6 out of the expression to find the length of the rectangle
Answer: L = 2m+3
Step-by-step explanation: The area of a rectangle is found using the formula A=L*W. The area A=12m+18. The width is W=6. The length will be the expression where 6 times it gives 12m+18. The expression is 2m+3 since 6(2m+3) = 12m+18.

(1, 2), (2, -1), (3,0), (4, 1), and (5, 1) Do those points represent a function? Explain why or why not.
Answer:
The relation is a function
Step-by-step explanation:
Given
[tex](1, 2), (2, -1), (3,0), (4, 1),\ and\ (5, 1)[/tex]
Required
Determine if the points is a function or not
A relation can be expressed as: [tex](x_1,y_1), (x_2,y_2),(x_3,y_3)......(x_n,y_n)[/tex]
Where
[tex]x = domain[/tex]
[tex]y = range[/tex]
When any domain element occurs more than once, then the relation is not a function.
The domain of the above points are:
[tex]x = \{1,2,3,4,5\}[/tex]
In this case, no domain occur more than once; in other words, no x value occur more than once
Hence, the relation is a function
If a computer price is reduced by 43% in a sale to £376.20, find the original price
Answer:
£874.88Step-by-step explanation:
sale price = £376.20
reduced by = 43%
original price = ??
sale price = original price ( reduced rate)
£376.20 = original price ( 43% )
100
original price = £874.88
Which quotient shows the decimal placed correctly? A) 6÷0.5=1.2 B) 0.64÷2=3.2 C) 0.57÷5=0.114 D) 1.08÷0.3=0.36
Answer:
C) 0.57÷5=0.114
Step-by-step explanation:
Which quotient shows the decimal placed correctly?
Solving for each of the option
A) we are told that:6÷0.5=1.2
Hence: 6/0.5
= 12
Option A is wrong
B) we are told that: 0.64÷2=3.2
Hence: 0.64/2
= 0.32
Option B is wrong
C) we are told that: 0.57÷5=0.114
Hence: 0.57/5
= 0.114
Option C is correct
D) we are told that: 1.08÷0.3=0.36
Hence = 1.08/0.3
= 3.6
Option D is wrong
Therefore, option C is the only correct Option where the quotient shows the decimal placed correctly
