Answer: 5%
Step-by-step explanation:
First notice that she contributes $300 a month and annually means yearly, so find the amount that she contributes yearly by multiplying 300 by 12 because there are 12 months in a year.
300 * 12 = 3600
Now to find the percentage, divide the amount she contributes in year by her annual salary.
3600/ 72000 = 0.05
Convert 0.05 into a percent by multiplying 0.05 by one hundred.
0.05 * 100 = 5%

Answer:
y=2x+4
Step-by-step explanation:
Answer:
The slope-intercept equation is y=2x+4
Step-by-step explanation:
The y-intercept is where it crosses the y-axis, so 4, and to find the slope find perfect points or pretty points and rise then run. I took the point (0,4) and found the next pretty point (1,6) and rise/run it. In order to get to the next point you have to rise 2 and run 1 or 2/1 which is 2, so the slope is 2, then you plug it into the equation y=mx+b the y=intercept is b and the slope is m.

Answer:
x=10
Step-by-step explanation:
Perimiter is 2(x+y) with x and y being the two differend sides. First side is 3x and the second is 2x+4. 2(3x+2x+4)=108. 10x+8=108 10x=100 x=10.
The sides are 24 and 30
Please mark brainliest hope this helps :D
Answer:
x=10
Step-by-step explanation:
Since this is a rectangle, we know that the values of opposite sides are equal and that the perimeter is all of the sides' values combined. Therefore:
2(2x+4)+2(3x)=108
First, we need to distribute the 2s on the left side.
4x+8+6x=108
Combine like terms.
10x+8=108
Subtract the 8 from both sides.
10x=100
Divide by 10.
x=10

Given the figure above, determine
Answer:
∠ C = 55°
Step-by-step explanation:
∠ W and ∠ A are adjacent angles and are supplementary, then
∠ A = 180° - ∠ W = 180° - 134° = 46°
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the 2 angles from 180 for ∠ C
∠ C = 180° - (46 + 79)° = 180° - 125° = 55°

This can be determined by the concept of straight line. [tex]\bold{y=-2x+17}[/tex] is the slope-intercept form of [tex]2x+y=17[/tex].
Given: 2x + y = 17
As, we know that,
Equation of line is,
[tex]\bold{y=mx+c}[/tex]
Where, 'm ' gives the slope/gradient of the line and 'c' gives y-intercept.
From the given equation,
[tex]2x+y=17[/tex]
Solve it further , we get,
[tex]\bold{y=-2x+17}[/tex]
This is the slope-intercept form of [tex]2x+y=17[/tex].
Here, comparing this with [tex]y=mx+c[/tex], we get
m= -2 ( slope/gradient) and c= 17 (y-intercept)
So, slope / gradient of line : m= -2.

I need to find the answer to B
Answer:
a) The next two terms are: 13, 16
b) nth term of the sequence is [tex]\mathbf{a_n=3n-5}[/tex]
Step-by-step explanation:
a) Find the next two terms of sequence: -2,1,4,7 and 10
The common difference d: a₂-a₁ = 1-(-2)= 3
a₃-a₂= 4-1 = 3
a₄-a₃=7-4=3
So, common difference is : 3
Next two terms are: 10+3 = 13
13+3= 16
The next two terms are: 13, 16
b) Find nth term of the sequence
The nth term can be found using formula:
[tex]a_n=a_1+(n-1)d[/tex]
where a₁=First term and d=Common Difference
In the sequence given we have a₁=-2 and d=3
So, the nth term will be:
[tex]a_n=a_1+(n-1)d\\a_n=-2+(n-1)3\\a_n=-2+3n-3\\a_n=3n-5[/tex]
So, nth term of the sequence is [tex]\mathbf{a_n=3n-5}[/tex]
Last month, the online price of a powered ride-on car was $250. This month, the online price is $330. What is the percent of increase in the price of the car? Round the percent to the neartst tenth if necessary.
Answer: 32.0%
Step-by-step explanation:
The price of car last month = $250
The price of the car this month = $330
Increase in price = $330 - $250 = $80
Percentage increase = (Increase in price/Cost price last month) × 100
= $80$250 × 100
= 0.32 × 100
= 32.0%
The percent of increase in the price of the car is 32.0%.
A motel rents double rooms at $34 per day and single rooms at $27 per day. If 26 rooms were rented one day for a total of $807, how many rooms of each kind were rented? system of equations
Let, number of double rooms and single rooms are d and s.
d + s = 26 ....1 )
Hotel rents double rooms at $34 per day and single rooms at $27 per day.
34d + 27s = 807 ....2)
Solving equation 1 and 2, we get :
34( 26 - s ) + 27s = 807
884 - 34s + 27s = 807
7s = 77
s = 11
And d = 26 - 11 = 15
Therefore, number of double rooms and single rooms are 15 and 11.
Hence, this is the required solution.

If the point R (x, y) is equidistant from two points P (- 3, 4) and Q (2, – 1), prove that
y = x + 2.
Answer:
see explanation
Step-by-step explanation:
Calculate the distance between (x, y) and the 2 given points and equate them.
Using the distance formula
d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = (x, y) and (x₂, y₂ ) = P(- 3, 4)
d = [tex]\sqrt{(-3-x)^2+(4-y)^2}[/tex]
Repeat with (x₁, y₁ ) = (x, y) and (x₂, y₂ ) = Q(2, - 1)
d = [tex]\sqrt{(2-x)^2+(- 1- y)^2}[/tex]
Equating both distances
[tex]\sqrt{(2-x)^2+(-1-y)^2}[/tex] = [tex]\sqrt{(-3-x)^2+(4-y)^2}[/tex]
Square both sides
(2 - x)² + (- 1- y)² = (- 3 - x)² + (4 - y)² ← expand and simplify both sides
4 - 4x + x² + 1 + 2y + y² = 9 + 6x + x² + 16 - 8y + y²
subtract x² + y² from both sides
5 - 4x + 2y = 25 + 6x - 8y ( add 8y to both sides )
5 - 4x + 10y = 25 + 6x ( subtract 5 from both sides )
- 4x + 10y = 20 + 6x ( add 4x to both sides )
10y = 10x + 20 ( divide all terms by 10 )
y = x + 2 ← as required

Solution:
Change the divisor 6.410251 to a whole number by moving the decimal point 6 places to the right. Then move the decimal point in the dividend the same, 6 places to the right.
We then have the equations:
2000000 ÷ 6410251 = 0.312

the graph below models an exponential relationship. drag one equation and one table to match the relationship shown.
Answer: y=-2^x is an equation.
I got the second one wrong.
The base of the exponential relationship that gives the graph that is below
the horizontal x-axis has a negative constant coefficient.
The equation that matches the given relationship is the option; y = -2ˣThe table that matches the relationship is the option;
[tex]\begin{tabular}{|c|c|c}x&y\\0&-1\\1&-2\\2&-4\end{array}\right][/tex]Reasons:
Points on the graph are; (0, -1) (1, -2), and (2, -4).
The above points can be presented in a tabular form as follows;
[tex]\begin{tabular}{|c|c|c}x&y\\0&-1\\1&-2\\2&-4\end{array}\right][/tex]
The above table which corresponds with the first table is the table that
matches the relationship of the graph.
By using the equation, y = -2ˣ, we have;
At x = 0, y = -(2⁰) = -1 which gives the point (0, -1)
At x = 1, y = -2¹ = -2, which gives (1, -2)
At x = 2, y = -2² = -4, which gives (2, -4)
The above points are the points on the graph, therefore, the equation is the option; y = -2ˣ
