If you would like to solve (25 * x^2) / (5 * x) + (8 * x^2) / x.
it would be easy calculate this using the following steps:
(25 * x^2) / (5 * x) + (8 * x^2<span>) / x = 5 * x + 8 * x = 13 * x
</span>
<span>The correct answer would be 13 * x.</span>
Answer:
Part A: 4/9
Part B: 12 students
Step-by-step explanation:
27 * 0.44444444 = 12 (this is the number of students who preferred snowboarding). So the fraction would be 12/27, which simplifies to 4/9.
1. You must apply the formula for calculate the volume of a cone and and the volume of a cylinder. Then, you must sum both volumes to obtain the volume on the figure attached.
2. Volume of the cone:
Vcone=1/3(πr²h)
π=3.14
r=4 mm/2
r=2 mm
h=3 mm
3. When you substitute the values above into the formula, you obtain:
<span>
Vcone=1/3(πr²h)
</span> Vcone=12.56 mm³
4. The volume of the cylinder is:
Vcylinder=<span>πr²h
</span>
π=3.14
r=4 mm/2=2 mm
h=2 mm
5. <span>When you substitute the values above into the formula, you obtain:
</span>
Vcylinder=25.12 mm³
6. The volume of the figure is:
Vt=Vcone+Vcylinder
Vt=12<span>.56 mm³+25.12 mm</span>³
Vt=37.68 mm³
Answer:
Nathan weighs 12 more pounds than Marty.
Step-by-step explanation:
If Marty weighs 64 pounds and Nathan weighs 76 pounds, we can subtract the weight of Marty from Nathan to get our answer.
In case Nathan was actually 476 pounds, the answer would be 412.
