Your answer is going to be a=1
Step-by-step explanation:
First things first, we want all the letters on the left side and all the numbers on the right side. So, you have to get rid of the three. In order to get rid of the three you have to take it away, so A/5=8-3. Then it will become A/5=5. After that you want to have A all by itself so divide it by 5, A/5=5/5. Then it will become A=1. Hope this helps! :)

A 15-pound bag of apples cost $6.30. At that rate, how much would a 29-pound bag of apples cost?
Answers
Answer:
here,
15 pound bag =$6.30
or, 1 pound bag = 6.30/15
or, 1 pound bag = $0.42
or,29 pound bag = 29 X $ 0.42
or, 29 pound bag = $ 12.18
Hence, a 29 pound bag of apple cost $12.18

Danielle earns $36.80 for 4 hours of yardwork. MacKenzie earns $50.40 for 6 hours of yardwork.Who earns more money per hour? How much more?
Answers
Answer:
Danielle earns $1.20 more than Mackenzie (per hour)
Step-by-step explanation:
To find out how much money per hour each person earns, you would divide the earinings by the number of hours;
Danielle: $36.80/4 = $9.20 per hour
MackKenzie: $50.40/6 = $8.40 per hour
To find out how much extra Danielle earns, you would subtract 8.40 from 9.20;
9.40 - 8.20 = $1.20
Thus, Danielle earns $1.20 more than Mackenzie per hour.

Ingrid hit a golf ball. The height of the ball (in meters above the ground) t seconds after being hit is modeled by
h(t)=-5t^2+30t
1) Rewrite the function in a different form (factored or vertex) where the answer appears as a number in the equation.
2) How many seconds after being hit does the ball reach its highest point?
__________seconds
Answers
Answer:
[tex]\huge\boxed{\text{1. } h(t) = -5(t-3)^2 + 45}[/tex]
[tex]\huge\boxed{\text{2. 3 seconds}}[/tex]
Step-by-step explanation:
If we're looking for the point at with the ball reaches its highest point, we want to find the graph's vertex. In order to get the equation into a form with the vertex in it, we need to convert the equation into vertex form. This is an equation in the form [tex]y=a(x-h)^2 + k[/tex], h being the x value of the vertex, and k being the y value of the vertex.
In order to convert our equation, [tex]-5t^2+30t[/tex] into vertex form, we can algebraically manipulate it to get it into the form we want.
[tex]-5t^2 +30t[/tex] [tex]-5 \cdot t^2 + 30t[/tex] (Separate the -5 from the t^2)[tex]-5(t^2-6t+0)[/tex] (Factor out a -5)[tex]-5(t^2 -6t + (-3)^2 - (-3)^2 + 0)[/tex] (Completing the Square)[tex]-5((t-3)^2 - (-3)^2 + 0)[/tex] (Binomial Formula)[tex]-5((t-3)^2 - 9)[/tex] (Simplify)[tex]-5(t-3)^2 + 45[/tex] (Factor the -5 back in)Therefore, our equation with the vertex in it is [tex]-5(t-3)^2 + 45[/tex]. To find the vertex, we can examine the equation to find the values of h and k in the formula [tex]y=a(x-h)^2 + k[/tex] (where the vertex coordinates are (h, k)).
It seems that h is 3 and k is 45. Therefore, the coordinate of the vertex is (3, 45). Since it asks for how many seconds after being hit does the ball reach its highest point, we would take the x value since x represents seconds. This is 3. Therefore, the ball reaches its highest point after 3 seconds.
Hope this helped!

What is the area trapezoid ABCD A(-1,5) B(3,2) C(0,-2) D(-13,-11)
Answers
Answer:
62.5
Step-by-step explanation:
slope of AB = (5-2)/(-1 - 3) = -3/4
slope of BC = (2 - -2)/(3-0) = 4/3
AB ⊥ BC (slope -3/4 vs 4/3)
seg AB = √(-1 - 3)² + (5 - 2)² = √25 = 5
seg BC = √(3 - 0)² + (2 - -2)² = √25 = 5
seg AD = √(-1 - -13)² + (5 - -11)² = √400 = 20
Area (BC + AD) * AB / 2 = (5 + 20) * 5 / 2 = 62.5

PLS HELP!!! due to inflation nominal prices are usually there were to demand increases. After the second increase the price for a certain item was twice as big as the original. By what percent was the first increase, if the second increase was 25%
Answers
Answer:
The first increase was of 60%.
Step-by-step explanation:
The initial value of the product is x.
The first increase was of y.
The second increase is of 25%, that is, 1.25.
The final price was double the original, so 2x.
This situation can be modeled by the following equation:
[tex]xy(1.25) = 2x[/tex]
We want to find y.
Simplifying by x
[tex]1.25y = 2[/tex]
[tex]y = \frac{2}{1.25}[/tex]
[tex]y = 1.6[/tex]
After the first increase, the value was 1.6 of the original value, that is a increase as a percent of (1.6 - 1)*100 = 60%.

How to derive a sinusoidal expression?We must figure out the periodic phenomenon's amplitude, period, and vertical shift in order to create a sinusoidal function that models it. Additionally, we must choose between using a sine or a cosine function and calculate the ensuing phase shift.
Given
A = 5+1 = 6
Shift = 21
ω =- π/3[because of 4th quadrant]
exp = Asin[-ωt] + shift
=-Acosωt + shift = -6cosπ/3 t + 21
