Answer:

The algebraic expression is (P-0.15p) = 0.85p

Step-by-step explanation:

Here, we want to write an algebraic expression to model the situation at hand;

Original price p of an item less a 15% discount

What this mean is that we want to remove a 15% discount from the original price P

That term ‘less’ means we are subtracting

so 15% of p would be;

15/100 * p = 15p/100 = 0.15p

So 15% of P less P is (P-0.15P) = 0.85P

6 + 2/5b = 12<br><br> What does “b” equal?
Elis [28]

Answer:

B = 15

Step-by-step explanation:

<u>Combine multiplied terms into a single fraction</u>

6 + 2b/5 = 12

<u>Subtract 6 from both sides</u>

6 + 2b/5 <em>(-6)</em> = 12 <em>(-6)   </em>= 2b/5 = 6

<u>Multiply all terms by the same value to eliminate fraction denominators</u>

2b/5 <em>( x 5) </em>= 6<em> (x 5)</em>

<em />

<u>Simplify</u>

2b = 30

What is the exact volume of the figure?
uranmaximum [27]

Answer: 890.12 cm^3

Step-by-step explanation:

The formula for the volume of a cylinder is

V=\pi *r^2*h

V=628.3185307 cm^3

or simply

V=628.32 cm^3

Since, you know the radius of the hemisphere on top, you also know the radius since the height of the hemisphere is the same as it is wide.

Next, the formula for the volume of a sphere is

V=\frac{4}{3} \pi *r^3

so the volume of a hemisphere is half of that or:

V=\frac{2}{3} *\pi *r^3

V= 261.7993878 cm^3

or simply

V=261.80 cm^3

Finally, you add both of the volumes together to get

V= 890.1179185 cm^3

or simply

V=890.12 cm^3

Solve for x. 4x − 33=7
tatuchka [14]

Note the equal sign. What you do to one side, you do to the other.

Do the opposite of PEMDAS. First, add 33 to both sides

4x - 33 (+33) = 7 (+33)

4x = 40

Next, divide by 4

4x/4 = 40/4

x = 40/4

x = 10

10 is your answer

hope this helps
