Just find the number that can divide by the whole. Say the question was
A pet shop have 20 pets. The same amount of pets are in each room. How many rroms could there be?
If there were 4 rooms, 5 pets would be in each. 20÷4=5. 4 goes into 20 so 4 could be an answer.
If there were 3 rooms, 6 rooms would have 3 pets and 2 would be left over. So it wouldn't work. You just need to find the number that goes into the whole with no remainder.
Find the equation of the line from given point and slope.....
a) passes through (-5,4) and has slope, m=1/2
Answer:
Slope-intercept form:
[tex]y=\dfrac12x+\dfrac{13}2[/tex]
Standard form:
[tex]x-2y=-13[/tex]
Step-by-step explanation:
Point-slope form of a linear equation: [tex]y-y_1=m(x-x_1)[/tex]
(where [tex]m[/tex] is the slope and [tex](x_1,y_1)[/tex] is the point)
Given:
[tex]m=\dfrac12[/tex][tex](x_1,y_1)=(-5,4)[/tex]Substituting these values into the point-slope formula:
[tex]\implies y-4=\dfrac12(x+5)[/tex]
[tex]\implies y-4=\dfrac12x+\dfrac52[/tex]
[tex]\implies y=\dfrac12x+\dfrac{13}2[/tex]
Slope-intercept form:
[tex]y=\dfrac12x+\dfrac{13}2[/tex]
Standard form:
[tex]x-2y=-13[/tex]

If The perimeter of a square is 48 meters what is the length of the diagonal
Answer:
approximately 17
Step-by-step explanation:
Answer:
16.97m
Step-by-step explanation:
We know that, all the 4 sides of a square are equal.
Given that,
Perimeter of the square is 48m
First, let us find the length of a side the square.
For that, let the length of a side be x.
Therefore,
x + x + x + x = 48
4x = 48
Divide both sides by 4.
x = 12 m
Now let us find the length of the diagonal using Pythagorean theorem.
For that let the length of the diagonal be y.
So,
12² + 12² = y²
144 + 144 = y²
288 = y²
√288 = y
16.97 m = y
Therefore,
The length of the diagonal is 16.97m

The area of a circle is 65.71cm2.
Find the length of the radius rounded to 2 DP.
Answer:
5 cm
Step-by-step explanation:
Area of a circle: [tex]\pi r^{2}[/tex] {r=radius}
[tex]\pi r^2=65.71cm2[/tex]
[tex]r^2=65.71/3.14[/tex] [tex](\pi =3.14)[/tex]
[tex]r^2=20.92[/tex]
[tex]r=\sqrt{20.92} =4.57cm[/tex]
[tex]r=4.57=5cm[/tex]
[tex]r=5cm[/tex]

The graph of the parent functions f(x)=x^3 is translated to form g(x)=(x-7)^3+9. The point (0,0) on the graph of f(x) corresponds to which point on the graph of g(x)
Answer:
(7, 9)
Step-by-step explanation:
The (x-7) indicates that the graph will be shifted to the RIGHT 7 units. The +9 at the end of the equation means the graph will be shifted UP 9 units.
So the point (0,0) will land at (7,9)
A line intersects the points
(-2,9) and (3, -11).
What is the slope of the line in
simplest form?
m = [?]
[tex]\\[/tex]Answer:
m = - 4
Step-by-step explanation:
Slope Formula: [tex]m=\frac{y_{2}- y_{1} }{x_{2}- x_{1} }[/tex]
Substitute (-2,9) and (3,-11) into m = [tex]\frac{y_{2} -y_{1} }{x_{2} x_{1} }[/tex]
= [tex]m=\frac{-11-9}{3-(-2)}[/tex]
m = -4
Answer:
Slope (m) = -4
Step-by-step explanation:
Given :-
Points (-2, 9) and (3, -11)
To Find :-
Slope (m)
Solving :-
m = y₂ - y₁ / x₂ - x₁
= -11 - 9 / 3 + 2
= -20 / 5
= -4
Solution :-
Slope (m) = -4

Mr. Moretti is making welcome bags to give to the 18 students in his homeroom on the
first day of school. He puts m mechanical pencils in each bag. He puts twice as many
regular pencils in each bag.
Which expression represents the total number of pencils Mr. Moretti gives to his students? Choose ALL that apply
Answer: 18 (m + 2m); 18m + 18 (2m); 54m
Step-by-step explanation:
The expression that represent the total no of pencil Mr. Moretti gives to his students is 18 (m + 2m); 18m + 18 (2m); 54m.
Given that,

NO LINKS!!! Solve each triangle. Part 2a
NOT A MULTIPLE CHOICE
1a. A= 40°, B= 20, a= 2
2b. A= 50°, C= 20°, a= 3
3c. B= 70°, C= 10°, b= 5
4d. A= 70°, B= 60°, c= 4
Answer:
Sum of interior angles of a triangle = 180°
Sine rule to find side lengths:
[tex]\dfrac{a}{\sin A}=\dfrac{b}{\sin B}=\dfrac{c}{\sin C}[/tex]
----------------------------------------------------------------------
Question 1a
Given: A = 40°, B = 20°, a = 2
40° + 20° + C = 180°
⇒ C = 120°
[tex]\dfrac{2}{\sin 40}=\dfrac{b}{\sin 20}=\dfrac{c}{\sin 120}[/tex]
[tex]\implies b=\sin20 \cdot\dfrac{2}{\sin 40}=1.064177772...[/tex]
[tex]\implies c=\sin 120 \cdot \dfrac{2}{\sin 40}=2.694592711...[/tex]
----------------------------------------------------------------------
Question 2b
Given: A = 50°, C = 20°, a = 3
50° + 20° + B = 180°
⇒ B = 110°
[tex]\dfrac{3}{\sin 50}=\dfrac{b}{\sin 110}=\dfrac{c}{\sin 20}[/tex]
[tex]\implies b=\sin 110 \cdot\dfrac{3}{\sin 50}=3.680044791...[/tex]
[tex]\implies c=\sin 20 \cdot\dfrac{3}{\sin 50}=1.339426765...[/tex]
----------------------------------------------------------------------
Question 3c
Given: B = 70°, C = 10°, b = 5
70° + 10° + A = 180°
⇒ A = 100°
[tex]\dfrac{a}{\sin 100}=\dfrac{5}{\sin 70}=\dfrac{c}{\sin 10}[/tex]
[tex]\implies a=\sin 100 \cdot \dfrac{5}{\sin 70}=5.240052605...[/tex]
[tex]\implies c=\sin 10 \cdot \dfrac{5}{\sin 70}=0.9239626545...[/tex]
----------------------------------------------------------------------
Question 4d
Given: A = 70°, B = 60°, c = 4
70° + 60° + C = 180°
⇒ C = 50°
[tex]\dfrac{a}{\sin 70}=\dfrac{b}{\sin 60}=\dfrac{4}{\sin 50}[/tex]
[tex]\implies a=\sin 70 \cdot \dfrac{4}{\sin 50}=4.906726388...[/tex]
[tex]\implies b=\sin 60 \cdot \dfrac{4}{\sin 50}=4.522063499...[/tex]

Step-by-step explanation:
First, find the rate of change of the line:

Find the EXACT circumference if the area is 196π square feet. Unit of measurement is feet or ft
Answer:
87.9645943005 feet
Step-by-step explanation:
The formula for the area of a circle is pi x radius to the power of 2. What number to the power of 2 is 196? 14.
So, the radius is 14.
The formula for the circumference of a circle is pi x diameter. If the radius is 14, the diameter is 28.
28 x pi = 87.9645943005
