Step-by-step explanation:
see the attached figure to better understand the problem
we know that
The surface area of a rectangular prism is equal to
where
B is the area of the base
P is the perimeter of the base
h is the height of the rectangular prism
<em>Find the area of the base B</em>
<em>Find the perimeter of the base P</em>
The height of the prism h is
substitute the values
The total amount of screen needed is 22 ft^2
Answer:
53 Meters.
Step-by-step explanation:
34*34 + 41*41 = 2837.
1156 + 1681 = 2837.
The square root of 2837 would be your answer.
34*34 + 41*41 = 53.26349 * 53.26349
a*a + b*b = c*c.
a² + b² = c².
Answer:
The equation that represents the battery charge in Sanchez's phone as a percentage t hours after he left his house is B(t) = 30 - 3*t.
Step-by-step explanation:
The initial state of the battery on Sanchez's phone is 30% so in time t equals zero the battery should be at that value and as time progresses the battery should lose battery charge at a rate of 3% for each hour. We can write this in an equation form by taking the initial state and subtract it by the rate multiplied by the value of time. We have:
B(t) = 30 - 3*t
The equation that represents the battery charge in Sanchez's phone as a percentage t hours after he left his house is B(t) = 30 - 3*t.
D is the correct answer.
When you add fractions, the answer is always rational.
1/5+-2/3= 3/15-10/15 = -7/15
A B and C are all irrational because they are nonterminating and nonrepeating decimals, which cannot be represented as a ratio of two integers. When you add a fraction to an irrational number, the result is still irrational.
