Answer:
$7.00
Step-by-step explanation:
The discount is 75% off. To answer this question, multiply n (the original price) by (1.00 - 0.75): 0.25n = $1.75.
Solving this for n, we get $7.00
You can solve for volume using radius or diameter.
Sphere Volume = <span> 4/3 • <span>π <span>• r³ <span> = <span>( <span>π <span>•d³)/6
We're given the diameter so let's use that.
Volume = PI * d^3 / 6
</span></span></span></span></span></span></span>
<span>Volume = 3.14159 * 3.0^3 / 6
</span>
<span>Volume = 3.14159 * 9 / 2
</span><span><span><span><span>Volume = </span>14.137 cubic centimeters
</span></span></span>
Answer:
Step-by-step explanation:
<u>Solve for x:</u>
- 1/2 (4x - 8) + 3x = 36
- 2x - 4 + 3x = 36
- 5x - 4 = 36
- 5x = 40
- x = 40/5
- x = 8
Answer:
49.5 ounces the flower
3 pounds, 1.5 ounces
Step-by-step explanation:
Given that :
24 cupcakes 9 ounces of flower
Number of ounces of flower required for 132 cupcakes will be x
Using cross multiplication method :
24 cupcakes = 9 ounces
132 cupcakes = x ounces
Cross multiply :
24 * x = 132 * 9
24x = 1188
divide both sides by 24 to isolate x
x = 49.5
Hence, 49.5 ounces the flower is required for 132 cupcakes
To express in pounds :
1 pound = 16 ounces
49.5 ounces = 3 pounds 1.5 ounces
Answer:
Step-by-step explanation:
s = √( 4.2*4.2 + (s/2)(s/2) )
s = √( 4.2*4.2 + (s^2/4) )
s^2= 4.2*4.2 + (s^2/4)
s^2 - (s^2/4) = 4.2*4.2
(4s^2/4) - (s^2/4) = 4.2*4.2
(3s^2/4) = 4.2*4.2
(3/4)s^2 = 4.2*4.2
s^2= 4.2*4.2*(4/3)
s = √( 4.2*4.2*(4/3) )
s = 2*4.2 * √( 1/3 )
s = 4.84974226119
answer:
perimeter = 3 * 4.84974226119
perimeter = 14.5492267836 meters
