Answer:

40%

Step-by-step explanation:

Original price = x

Sale = 20% off

20% / 100 = 0.2 to convert from a percent to a decimal

Sale = x - 20% of x = x - 0.2x = 0.8x

Sale price = y = 0.8x

Reduction of sale prices = 25% = 0.25

Reduction = y - 25% of y = y - 0.25y = 0.75y

End price in terms of original price (x):

0.75y = 0.75(0.8)x

          = 0.6x

End price = 0.6 or 60% of original price, coming out to a 100-60 = 40% overall percentage reduction

What is the volume of this rectangular prism? <br> 3ft by 6 1/4 ft by 14 ft
Liula [17]
We can find the volume of any rectangular prism by simply multiplicating its height, length and width.

Also, lets change that 6 1/4 to 6.25, or 25/4 if you like. I’m gonna use 6.25.

If we take volume as “V”, then:

V = L * W * H
V = 3ft * 6.25ft * 14ft
V = 262.5 ft^3 (Its ft cubed because we multiplied by ft three times.)

Joan waters her plants each day with gallons of water. With a new irrigation system in place, she uses gallons of water each day
vampirchik [111]

Answer:

172\frac{1}{2} gallons

Step-by-step explanation:

Considering she waters her plants with 25 1/2 gallons  i.e 51/2

and with the new system, she does it with 19 3/4 i.e 79/4

taking the difference:

\frac{51}{2} - \frac{70}{4} = \frac{23}{4} gallons per day

For 30 days:

30 x \frac{23}{4} = 172.5 or 172\frac{1}{2} gallons

HELP! A semi circle of radius 6 is centered at the origin as shown. A rectangle has two of its vertices at (5,0) and (-5,0) and
Ugo [173]

The Area of rectangle is "30 \ unit^2" and the equation of the semi circle is "y = \sqrt{36-x^2}".

According to the question,

The vertices of rectangle,

(5, 0) and (-5, 0)

Length,

l = 10 unit

Breadth,

b = 3 unit

Radius of semi circle,

r = 6

Centre of origin,

(0, 0)

As we know,

→ The Area of rectangle is:

= Length\times Breadth

= 10\times 3

= 30 \ unit^2

and,

→ The Equation of semi circle is,

y = \sqrt{r^2-x^2}

by substituting the values, we get

  =\sqrt{(6)^2-x^2}

  = \sqrt{36-x^2}

Thus the above is the correct answers.
