Answer:
5.04%
Step-by-step explanation:
To find the percent difference (which represents the tax percent/rate), we can first use the formula
(final value - inital value) / (inital value)
Our final value is 7.30, and our initial value is 6.95. Plugging this into the formula, we get
(7.3-6.95)/(6.95) = 0.0504
This is a decimal. To convert a decimal to a percent, we simply multiply the decimal by 100, getting
0.0504 * 100 = 5.04% as our answer

Step-by-step explanation:
A lawn fertilizer company is working on different formulas for lawn fertilizer. They want to examine the difference between their “Original Formula” and their “Improved Formula”.
The table below shows the height of different lawns, in millimeters, using the various fertilizer formulas.
The model for each lawn is shown in the table below.
Lawn Fertilizer Model
A (Control Group) f(x)=7x+6
B (Original Formula) f(x)=1.5x2+5.5x+11
C (Improved Formula) f(x)=9⋅2x
Use the model to estimate the height of the lawn after 10 weeks.

Find the value of 'x
Answer:
x = 16
Step-by-step explanation:
The sum of the angles of a triangle are 180
128+ 2x-3 +23 = 180
Combine like terms
2x+148=180
Subtract 148 from each side
2x+148 -148 = 180-148
2x = 32
Divide by 2
2x/2 = 32/2
x =16
solve for x:
-x/3 = 2
Answer:
x = -6
Step-by-step explanation:
-x/3 = 2
Multiply each side by -3 to isolate x
-x/3 * -3= 2*-3
x = -6
Answer:
x= -6
Step-by-step explanation:
you want to issolate x.
Start by getting rid of that divison by inversing it. The inverse of division is multiplication, so we multiply 2 by 3 to get 6.
Now -x= 6
in order for it to be truely isolated, we must inverse the negative sign.
its x= -6

Answer:
(1,3)
Step-by-step explanation:
This might be wrong, sorry.
y+4x=7
I would think the pair is
(1,3)
Point M is located at (3,-2) on the coordinate plane. Point M is reflected over the
x-axis to create point M'. What ordered pair describes the location of M'?

Answer:
Slope is -3
y-intercept is -3 and equation is y=-3x-3
Answer:
Slope: -3
y-intercept: -3
Equation: y = -3x - 3
Step-by-step explanation:
1. To get the slope (m):
m = rise / run = -3 / 1 --> it's negative 3 since the slope is going downwards
2. the y-intercept is the point that crosses the y-axis or when the x point is 0, so (0, -3)
3. Put is all together: y = -3x - 3

If the height of the pyramid were increased to 512 ft and the height to base area ratio of the pyramid were kept constant, by what percentage would the volume of the pyramid increase
Complete question:
The base of a pyramid covers an area of 14.0 acres (1 acre = 43, 560 ft² ) and has a height of 481 ft. If the volume of a pyramid is given by the expression V = bh/3, where b is the area of the base and h is the height. If the height of the pyramid were increased to 512 ft and the height to base area ratio of the pyramid were kept constant, by what percentage would the volume of the pyramid increase
Answer:
The percentage increase of the volume is 6.45 %
Step-by-step explanation:
The volume of pyramid is calculated as;
V = bh/3
The initial volume of the pyramid is calculated as follows;
[tex]V = \frac{bh}{3} \\\\V_0 = (\frac{1}{3} ) \times (14 \ acres \ \times \frac{43,560 \ ft^2}{1 \ acre} ) \times (481 \ ft)\\\\V_0 = 97,777,680 \ ft^3[/tex]
The final volume of the pyramid when the height is increased to 512 ft.
[tex]V_1 = (\frac{1}{3} ) \times (14 \ acres \ \times \frac{43,560 \ ft^2}{1 \ acre} ) \times (512 \ ft)\\\\V_1 = 104,079,360 \ ft^3[/tex]
The percentage increase of the volume;
[tex]= \frac{104,079,360 - 97,777,680}{97,777,680} \times 100\%\\\\= 6.45 \ \%[/tex]
The volume of the pyramid will increase by 11.79%
The volume of a Pyramid is calculated using:
[tex]V = \frac{Bh}3[/tex]
Where:
B represents the base areah represents the heightWhen the height is increased from 458 to 512, then the initial and the final volumes are:
[tex]V_1 = \frac{458}{3}b[/tex]
[tex]V_2 = \frac{512}{3}b[/tex]
The percentage change is then calculated as:
[tex]\% Change = \frac{V_2 -V_1}{V_1} \times 100\%[/tex]
This gives
[tex]\% Change = \frac{512b/3 -458b/3}{458b/3} \times 100\%[/tex]
Simplify the numerator
[tex]\% Change = \frac{54b/3}{458b/3} \times 100\%[/tex]
Evaluate the quotient
[tex]\% Change = 0.1179 \times 100\%[/tex]
Express as percentage
[tex]\% Change = 11.79 \%[/tex]
Hence, the volume of the pyramid will increase by 11.79%

A box with a square base and open top must have a volume of 171500 c m 3 . We wish to find the dimensions of the box that minimize the amount of material used. First, find a formula for the surface area of the box in terms of only x , the length of one side of the square base. [Hint: use the volume formula to express the height of the box in terms of x .] Simplify your formula as much as possible.
Answer:
The dimensions of the box that minimize the amount of material used is length of square base x = 70 cm and height of box = 35 cm
Step-by-step explanation:
The volume of the box with square base is V = x²h where x = length of side of square base and h = height of box.
Now, the area of the of box open at the top with dimensions of length, l , width, w and height, h are
A = 2lh + lw + 2wh
Now for a box of square base, l = w = x.
So, A = 2xh + x² + 2xh
A = x² + 4xh
Since V = x²h and V = 171500 cm³,
h = V/x² = 171500/x²
substituting h into A, we have
A = x² + 4xh
A = x² + 4x(171500 cm³/x²)
A = x² + 4 × 171500 cm³/x
A = x² + 686000 cm³/x
To find the value of x that minimizes A, we differentiate A with respect to x
So, dA/dx = d[x² + 686000 cm³/x]/dx
dA/dx = 2x - 686000 cm³/x²
equating this to zero, we have
2x - 686000 cm³/x² = 0
2x = 686000 cm³/x²
2x³ = 686000
x³ = 686000 cm³/2
x = ∛(343000 cm³)
x = 70 cm
To determine if this in a minimum dimension for A, we differentiate dA/dx and insert x = 70 cm
So, d²A/dx² = d[2x - 686000 cm³/x²]/dx
d²A/dx² = 2 + 3 × 686000 cm³/x³
d²A/dx² = 2 + 2058000 cm³/x³
with x = 70 cm, we have
d²A/dx² = 2 + 2058000 cm³/(70 cm)³
d²A/dx² = 2 + 2058000 cm³/343000 cm³
d²A/dx² = 2 + 6
d²A/dx² = 8 > 0
So, x = 70 is a minimum value for the dimension
Since h = 171500 cm³/x²
h = 171500 cm³/(70 cm)²
h = 171500 cm³/4900 cm²
h = 35 cm
So, the dimensions of the box that minimize the amount of material used is length of square base x = 70 cm and height of box = 35 cm
1/2(x-6.5) = 3.16 what is x?
Answer:
x =12.82
Step-by-step explanation:
1/2(x-6.5) = 3.16
Multiply each side by 2
1/2(x-6.5) *2 = 3.16 *2
(x-6.5) = 6.32
Add 6.5 to each side
(x-6.5+6.5) = 6.32+ 6.5
x =12.82
Answer: 12.82
Step-by-step explanation:
1/2(x-6.5)= 3.16
x=12.82
