Answer:
58.8 in²
Step-by-step explanation:
you have no calculator ?
since you clearly have a computer or smart phone - there are calculator apps on all of them.
you really just need to use the given numbers and multiply and add them following the formula. so, what is your problem ?
anyway,
2pi×r×h + 2pi×r²
h = 5.9
r = 1.3
2pi × 1.3 × 5.9 + 2pi × 1.3² = 2pi × 7.67 + 2pi × 1.69 =
= 58.8 in²

Answer:
(d) n > -4
Step-by-step explanation:
Divide by the coefficient of n. Because that is division by a <em>negative</em> number, reverse the inequality symbol.
n > (16/-4)
n > -4
Answer:
The solution to the equation is:
- <u>x = 2.5</u> or <u>x = 5/2</u>
Step-by-step explanation:
To find the solution to the equation, you only must operate the equation until you clear the x variable, with the next steps:
And we solve:
- 4x + 28 = 38 (we multiply 4 by x and 7)
- 4x = 38 - 28 (we pass the +28 to subtract to the right side of the equality and operate)
- x = 10 / 4 (we pass the 4 that is multiplying to divide to the right side of the equality)
- <u>x = 2.5</u> (we divide)
As you can see, <u><em>the solution of the equation is </em></u><u><em>x = 2.5</em></u><u><em> or </em></u><u><em>x = 5/2</em></u>
Put 7 in place of x 10-2(7)= 10-14=negative 4
Answer:
, 
Step-by-step explanation:
In a 45-45-90 relation triangle the two shortest sides will have equal length, meaning:
To find the hypotenuse we must multiply the shortest side by 
, both sides are equal so it doesn't matter which we multiply.
