The correct option is option B i.e., 36 + 9 = 3(12 + 3) is an equation representing distributive property.
What is distributive property ?
Distributive property states that the outcomes are the same whether the numbers in parenthesis are added before or after multiplication.
We know that according to the distributive property both sides must be equal such that the outcomes are same whether the numbers in parenthesis are added before or after multiplication. The expression for distributive property is given as : a(b + c) = ab + ac
So , checking the options one by one :
A) 36 + 9 = 45 ; is not an equation representing distributive property as it doesn't satisfy the criteria of a distributive property.
B) 36 + 9 = 3(12 + 3) is an equation representing distributive property as it satisfies the criteria mentioned above i.e.,
36 + 9 = 3 × 12 + 3 × 3
36 + 9 = 36 + 9
45 = 45
C) 36 x 9 = 9 x 36 is not an equation representing distributive property.
D) (12 + 3) × 3 = 3 × (12 + 3) is not an equation representing distributive property because both sides are written in the same way.
Therefore , correct option is option B i.e., 36 + 9 = 3(12 + 3) is an equation representing distributive property.

If theta is in quadrant II and cos theta= -3/5, what is sin 2 theta + cos 2 theta?
ANSWER
sin(2θ) + cos(2θ) = -31/25 = -1.24
EXPLANATION
If we do the inverse of the cosine to -3/5 we would get the angle θ. Then we can know the value of the sine:
[tex]\sin \theta=\sin (\cos ^{-1}(-\frac{3}{5}))=\frac{4}{5}[/tex]So we have:
• sin(θ) = 4/5
,• cos(θ) = -3/5
To find sin(2θ) + cos(2θ) we'll have to use the trigonometric identities:
[tex]\begin{gathered} \sin 2\theta=2\sin \theta\cos \theta \\ \cos 2\theta=1-2\sin ^2\theta \end{gathered}[/tex]Since we have the sine and cosine of theta, we can solve this:
[tex]\sin 2\theta=2\cdot\frac{4}{5}\cdot(-\frac{3}{5})=-\frac{24}{25}[/tex][tex]\cos 2\theta=1-2(\frac{4}{5})^2=1-2\cdot\frac{16}{25}=1-\frac{32}{25}=-\frac{7}{25}[/tex]The sum is:
[tex]\sin 2\theta+\cos 2\theta=-\frac{24}{25}-\frac{7}{25}=-\frac{31}{25}=-1.24[/tex]a child is covering a square board with mosaic tiles the board is 40×40cn each tile is 2 cm ×2 cm how many mosaic tiles are needed for one complete now
Answer:
Step-by-step explanation:
The area of the floor is 4×3=12 sqare meters
=12×100×100= 120000 square centimetres.
Area of each tile is 20×20=400 square centimetres.
Therefore number of tiles required will be
120000÷400 =300.
300 tiles will be required to cover the floor.
Select the table that represents a linear function. (Graph them if necessary.)
Step-by-step explanation:
any linear function represents a straight line (hence the name) and is therefore of the structure
y = f(x) = ax + b
"a" is the slope of the line, and it is represented by the ratio (y coordinate difference / x coordinate difference) when going from one point on the line to another point.
"b" is the y-intercept (the y-value when x = 0).
so, let's look at the answer options :
A.
x = 0 gives us b (the y value) : 2
so, then for x = 1, y = 3 ?
3 = a×1 + 2
a = 1
now, the next point must be also on the same line for the whole function to be linear (and that means the equation has to be true for all numbers involved) :
x = 2, y = 6
6 = 1×2 + 2 = 4
6 is for sure NOT 4, so this is not a linear function.
it is actually y = x² + 2
B.
x = 0 gives us b : 1
for x = 1, y = 3 ?
3 = a×1 + 1
a = 2
again, the next point must be on the same line :
x = 2, y = 9
9 = 2×2 + 1 = 5
9 is for sure NOT 5, so this is not a linear function.
it is actuality y = 3^x.
C.
x = 0 gives us b : 0
for x = 1, y = 1 ?
1 = a×1 + 0 = a
a = 1
the next point :
x = 2, y = 4
4 = 1×2 = 2
4 is for sure NOT 2, so this is not a linear function.
it is actually y = x².
D.
x = 0 gives us b : 3
for x = 1, y = 9
9 = a×1 + 3
a = 6
the next point(s) must fit :
x = 2, y = 15
15 = 6×2 + 3 = 12 + 3 = 15
correct
x = 3, y = 21
21 = 6×3 + 3 = 18 + 3 = 21
correct
yes, this is a linear function.
it is y = 6x + 3

Answer:
[tex]v_0=20.7\frac{m}{s}[/tex]
Explanation:
We are given the equation for the height:
[tex]h(t)=10+v_0t-4.9t^2[/tex]If we differentiate this equation, we get the equation of the velocity:
[tex]h^{\prime}(t)=v(t)=v_0-9.8t[/tex]The problem tells us that the object hits the ground at a velocity of -25m/s. We can write this:
[tex]-25=v_0-9.8t_0[/tex]Where t0 is the time when the object hits the ground, and the velocity is -25m/s
Now, we can solve for v0:
[tex]v_0=9.8t_0-25[/tex]And if we use this in the height h(t) equation, we can find the value of t0. At t0, the height is 0. Thus:
[tex]0=10+(9.8t_0-25)t_0-4.9t_0^2[/tex]And solve:
[tex]\begin{gathered} 0=10+9.8t_o^2-4.9t_0^2-25t_0 \\ 0=10-25t_0+4.9t_0^2 \end{gathered}[/tex]Next, we can use the quadratic formula to solve this:
[tex]\begin{gathered} t_{\pm}=\frac{-(-25)\pm\sqrt{(-25)^2-4\cdot4.9\cdot10}}{2\cdot4.9}=\frac{25\pm\sqrt{625-196}}{9.8}=\frac{25\pm\sqrt{429}}{9.8}=\frac{25\pm20.71231}{9.8} \\ . \\ t_+=\frac{25+20.71231}{9.8}=4.664521seconds \\ . \\ t_-=\frac{25-20.71231}{9.8}=0.43751seconds \end{gathered}[/tex]Let's see which of the two solutions is the time we are looking for.
Let's go back to our solution for v0:
[tex]v_0=9.8t_0-25[/tex]If we use t0 = 0.43751 s:
[tex]v_0=9.8\cdot0.46751-25=-20.7123m/s[/tex]This means that the initial velocity is negative, thus the object goes downwards. But, the problem tells us that initially the object is thrown upwards.
The correct value of t0 = 4.66 seconds
Now we can find v0:
[tex]v_0=9.8\cdot4.664521-25=20.712[/tex]Thus, v0 = 20.7 m/s

Based on the system of equations, the cost of using 19 HCF of water is $35.43
What is an equation?An equation is a mathematical statement that two or more values are equivalent.
Equations are stated to show that two mathematical expressions are equal using the equation sign (=).
Cost of using 17 HCF of water = $32.13
Cost of using 35 HCF of water = $61.83
Total cost of 17 HCF water = 17x + a
17x + a = 32.13 ... equation 1
Total cost of 35 HCF water = 35x + a
35x + a = 61.83 ... equation 2
Subtract equation 1 from equation 2:35x + a = 61.83
-17x + a = 32.13
18x = 29.70
18x = 29.7
x = 29.7/18
x = 1.65
Find a:17x + a = 32.13 ... equation 1
17(1.65) + a = 32.13
28.05 + a = 32.13
a = 4.08 (32.13 - 28.05)
The cost of 19 HCF of water:= 19(1.65) + 4.08

$40 for 2 dozen of doughnuts and 5 dozen of croissant is witten as
[tex]2x+5y=40\ldots\text{equation 2}[/tex]Applying Elimination to solve the two system of equation, we have
[tex]\begin{gathered} 6x+2y=42\ldots\text{equation 1} \\ 2x+5y=40\ldots\text{equation 2} \\ To\text{ eliminate x multiply equation 2 by 3 and equation 1 by 1} \\ 1\times(6x+2y=42)\rightarrow6x+2y=42 \\ 3\times(2x+5y=40)\rightarrow6x+15y=120 \end{gathered}[/tex]Then, subtract the equation obtained above
[tex]\begin{gathered} 6x+2y=42 \\ 6x+15y=120 \\ -13y=-78 \\ \text{Divide both sides by -13} \\ -\frac{13y}{-13}=-\frac{78}{-13} \\ \\ y=6 \end{gathered}[/tex]Hence Y=6
Then you Eliminate Y from eqaution 1 an d 2 by
Multiplying equation 1 by 5 and equation 2 by 2
[tex]\begin{gathered} 5\times(6x+2y=42)\rightarrow30x+10y=210 \\ 2\times(2x+5y=40)\rightarrow4x+10y=80 \end{gathered}[/tex]The sunbtract the equation obtained
[tex]\begin{gathered} 30x+10y=210 \\ 4x+10y=80 \\ 26x=130 \\ \text{Divide both sides by 26} \\ \frac{26x}{26}=\frac{130}{26} \\ \\ x=5 \end{gathered}[/tex]Hence X=5

The Richardson family needs 990272 per year to in their budget.
Mrs. Richardson works 22 hours a week.
Mr. Richardson works 40hours a week.
We need to calculate their hourly income.
Lets first calculate total weeks in a year.
We know that, a year has 365 days and a week has 7
So, total no. of weeks in a year = 365/7 = 52.143 weeks.
no. of weeks in a year = 52.143 weeks
Their weekly income = yearly income/no. of weeks in a year
So, weekly income = 990272/52.143
weekly income = 18991.466
Their hourly income = weekly income/working hours per week
Their weekly income is 18991.466 and,
working hours = 22 + 40 = 62 hours.
Their hourly income = 18991.466/62
Hourly income = 306.314

One interior angle of a triangle is 95.5°, and the other two interior angles are congruent. What is the degree measure of one of the congruent angles?
42.25°
47.75°
84.5°
90°
The sum of all interior angles of a triangle is 180° thus the measure of one of the congruent angles is 42.25° so option (A) is correct.
What is a triangle?A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are 3 sides and three angles in every triangle, some of which may be the same.
Let's suppose the two congruent interior angles are x degrees.
It is known that the sum of all three angles inside a triangle will be 180°.
So, m∠x+ m∠x + 95.5° = 180°
2m∠x = 180° - 95.5°
m∠x = 84.5/2 = 42.25°
Hence "The sum of all interior angles of a triangle is 180° thus the measure of one of the congruent angles is 42.25°".

in a class of 34 students 19 of them are girls what percentage of the class are girls give you answer to one decimal place
In class of 34 students, 19 of them are girls, then the percentage of girls in the class is 55.9%
The total number of students in the class = 34
Number of girls in the class = 19
The percentage is defined as the ratio that can be expressed as the fraction of 100. The percentage is often represented using the percentage sign "%"
The percentage of girls in the class = (Number of girls in the class/The total number of students in the class) ×100
Substitute the values in the equation
The percentage of girls in the class = (19/34)×100
= 0.559×100
= 55.9%
Hence, in class of 34 students, 19 of them are girls, then the percentage of girls in the class is 55.9%

Growing linearly, the balance owed on your credit card doubles from $600 to $1200 in 6 months. If the balance were growing according to the exponential function f(x)=600(1+0.1220)^x where x represents the number of months, what would the balance be after 6 months? Round your answer to the nearest cent.
Evaluate the given expression at x=6. This is, replace every x in the equation for 6 and solve:
[tex]\begin{gathered} f(6)=600(1+0.1220)^6 \\ f(6)=600(1.1220)^6 \\ f(6)=600\cdot(1.99506) \\ f(6)=1197.04 \end{gathered}[/tex]The balance after 6 months is 1197.04.
