Hey there,

Answer:

Difference = 1,435 - 1,220
                 = 215
% change = (Difference / Original) x 100%

% change = (215 / 1,435) x 100%
                 = 14.98257839721254%
                 = 15%

Hope this helps :D

Two-step equations with decimals and fractions<br><br> Solve for p.<br><br> −5(p+ 3/5 )=−4
GrogVix [38]

Answer:

1/5 or 0.2

Step-by-step explanation:

-5(p+3/5)=-4

Let's convert 3/5 to decimal form:

-5(p+0.6)=-4

Expand parentheses:

-5p-3=-4

Add -3 to both sides:

-5p=-1

Divide both sides by -5:

p=1/5 or 0.2

Hope this helps!

Spaceship Earth, a spherical attraction at Walt Disney World’s Epcot Center, has a diameter of 50 meters. Find the surface area
Black_prince [1.1K]

The surface area of Spaceship Earth is: 7850 m^2

Step-by-step explanation:

Given

Diameter of spherical structure = d = 50 meters

As the attraction is in the form of a sphere, its radius will be used to find the surface area.

Radius = r = \frac{d}{2} = \frac{50}{2} = 25\ m

The formula for surface area of sphere is:

SA = 4\pi  r^2\\= 4 * 3.14 * (25)^2\\= 4*3.14*625\\=7850\ m^2

The surface area of Spaceship Earth is: 7850 m^2

Keywords: surface area, sphere

Given that f(x) = 10x + 45, find f(7)
sattari [20]

Answer:

\boxed{\bf f(x) = 115}

Step-by-step explanation:

<u>Given polynomial </u><u>function </u>:-

f(x) = 10x +  45

<u>To </u><u>find</u> :-

\sf \: f(7)

<u>Solution:-</u>

\sf \implies \: f(x) = 10x + 45

Here, the value of x is 7(given).

So, <u>Substitute the value of x on the RHS and </u><u>on </u><u>LHS </u>:-

\sf \implies{f}(“7”) = 10(“7”) + 45

Simplify the RHS:-

<u>Multiply 10 and 7 :-</u>

\sf \implies{f}(7) = 10 \times 7 + 45

\sf \implies{f}(7) = 70 + 45

<u>Add 70 and 45 :-</u>

\sf \implies{f}(7) = 115

We're done!

Hence, the value of f(7) would be,

\sf \implies{f}(7) = 115

\rule{225pt}{2pt}

I hope this helps!
