Hannah opened a bank account. She placed $120 into the bank account and added $30 per week. Now she has $450 in her account. A. Write an equation that represents her savings. B. Find the number of weeks that have passed since she opened her savings account. Explain how you arrived at your answer
The equation that represents her savings is $450 = $120 + $30n.
The number of weeks that have passed since she opened her savings account is 11 weeks.
What equation represents her savings?Total amount saved = amount initially deposited + (amount added weekly x number of weeks)
$450 = $120 + $30n
Where n = number of weeks
In order to determine the value of n, take the following steps:
Combine similar terms = $450 - $120 = 30n
$330 = 30n
Divide both sides by 30
n = 11 weeks

Work out the size of an interior angle of a regular polygon with 24 sides.
Answer:
165°
Step-by-step explanation:
First, we need to find the sum of all the interior angles in the 24-sided polygon.
The equation for that is: 180 (n-2)
[n represents the number of sides]
180 (24-2)
180 (22)
3960
Then to find the measure of a single interior angle, just divide 24 from 3960.
3960 ÷ 24 = 165

Solve for X

2x – 18
U
4x - 29
PLEASE HELP!
Answer:
x = 15
Step-by-step explanation:
SV = ST + TU + UV , substitute values
4x - 29 = 13 + 6 + 2x - 18 , that is
4x - 29 = 2x + 1 ( subtract 2x from both sides )
2x - 29 = 1 ( add 29 to both sides )
2x = 30 ( divide both sides by 2 )
x = 15
The points S, T, U, and V are collinear points. Then the value of the variable x will be 15.
What are collinear points?If the points are in a line, then the points are collinear points.
Let A, B, C, and D are collinear point. Then the condition of the collinear will be
AB + BC + CD = AD
The line segment SV is given.
And the point T and U lies on the line segment SV.
The length of ST is 13, the length of TU is 6, the length of UV is 2x - 18, and the length of SV is 4x - 29.
It is clear that the points S, T, U, and V are collinear points.
ST + TU + UV = SV
13 + 6 + 2x - 18 = 4x - 29
2x + 1 = 4x - 29
2x = 30
x = 15
The value of the variable x will be 15.

In the given problem, the sum of [tex]\frac{4}{6}[/tex] and [tex]\frac{4}{6}[/tex] is [tex]\frac{4}{3}[/tex].
The sum is the result of adding two or more numbers or terms. In other words, it is the process of bringing two or more numbers together to produce a new result or total. The symbol for the sum is "+".
The sum can be performed on any kind of number, including whole numbers, integers, rational numbers, real numbers, and complex numbers. The rules for addition are the same for all types of numbers.
To find the sum of [tex]\frac{4}{6}[/tex] and [tex]\frac{4}{6}[/tex],
[tex]\frac{4}{6}[/tex] + [tex]\frac{4}{6}[/tex] = 2 [tex]\times \ \frac{4}{6}[/tex]

Henry starts his first count at 815.
How many times does his frog have to jump to get to 15?
Explain your thinking below.
8 times does his frog have to jump to get to 15.
Why do frogs hops?The frog jump is a plyometric exercise that primarily works your quads, glutes, and hip flexors. This exercise strengthens the wrists, ankles, knees, hips, and ligaments in the joints. It also stretches your hips and ankles while strengthening your legs and lower back muscles.Frogs jump and hop around using their long, strong legs. Toads, on the other hand, prefer to walk rather than hop. They only move modest distances when they jump or hop. As a result, they don't require long legs like a frog, hence their legs are quite short.The starting number is 815.
the frog hops once (715)

Find the slope of the line passing through the points (-4, -4) and (2, 5)
Answer: The slope is 3/2
Step-by-step explanation:
To find the slope, you need to find the difference between the y coordinates and divide it by the difference in the x coordinates.
The y coordinates are -4 and 5
The x coordinates are -4 and 2
-4 -5 = - 9
-4 - 2 = -6
-9/-6 = 3/2
Rounded to the nearest whole degree, what is the measure of angle boa? ° rounded to the nearest tenth of a centimeter, what is the length of arc bac? cm
1) The measure of ∠BOA is 60.16°.
2) the length of arc BAC is 14.68cm.
What is the formula for arc length?
Arc length = Central Angle(in radian) * Radius
So, length of arc AC = (45π/180) * 8
Arc AC = 2π
Arc AC = 6.28cm
So, length of arc BAC = arc AC+ arc AB
Arc BAC = 6.28 +8.4
Arc BAC = 14.68cm
∠BOA = length of Arc AB / Radius
∠BOA = 8.4/8 = 1.05 radian
∠BOA= 1.05 *(180/π)°
∠BOA=60.16°
Therefore, 1) The measure of ∠BOA is 60.16°.
2) the length of arc BAC is 14.68cm.

.
b – 7 = 12
Answer:
b=19
Step-by-step explanation:
Given:
b-7=12
Adding 7 to both sides
b-7+7=12+7
b=19
Answer:
b = 19
Step-by-step explanation:
The easiest way to solve equations like this is to do something referred to as "undoing in reverse order." Now, to undo subtraction, you have to add.
b - 7 = 12
b - 7 (+ 7) = 12 (+7)
b = 19
Therefore, the answer is 19.

Let's complete the square
f(x) = x^2 + 6x + 8
y = x^2 + 6x + 8
y-8 = x^2 + 6x
y-8+9 = x^2+6x+9 .... see note below
y+1 = (x+3)^2
y = (x+3)^2-1
note: I added 9 to both sides due to taking half of the 6, and then squaring that result.
We'll restrict x such that [tex]x \ge -3[/tex] to ensure that this function is one-to-one.
Now we need to swap x and y, and solve for y to get the inverse
y = (x+3)^2 - 1
x = (y+3)^2 - 1
x+1 = (y+3)^2
(y+3)^2 = x+1
y+3 = sqrt(x+1)
y = sqrt(x+1)-3
g(x) = sqrt(x+1)-3 is the inverse
The graph is shown below. The original function is in red. The inverse is in blue. The inverse is the result of reflecting the red curve over the dashed line y = x. So this explains why x and y swap places. Consequently, the domain and range also swap as well.
