Answer:
-18 or 18, the value of w is not clear, it looks like it can be either 3 or -3
Step-by-step explanation:
So if you substitute the variables for there actual value the equation would be 6(-3) or 6(3)
A negative times a positive is a negative so -3 or 3 times 6 is -18 or 18

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 ratio of boys to girls in a class is 3:5. There are 40 students in the class. How many
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

(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
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]

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
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
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.
Multiply.

Simplify the expression:
(5x6) (3x-2)=15xn. Find "n"
Answer:
[tex]\frac{6x-4}{x}[/tex]
Step-by-step explanation:
(5 x 6)(3x - 2) = 15xn
30(3x - 2) = 15xn
[tex]\frac{2}{1}[/tex] * (3x - 2) = ([tex]\frac{1}{2}[/tex]xn) * [tex]\frac{2}{1}[/tex]
6x - 4 = xn
n = [tex]\frac{6x-4}{x}[/tex]
You can't cross the 'x' out of the numerator or denominator because of the - 4 in the numerator.

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.

Step-by-step explanation:
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
