Answer:
$2000
Step-by-step explanation:
The formula for simple interest is:
Where
i is the interest earned
P is the initial deposit
r is the rate of interest (in decimal)
t is the time
Now, in the problem, it is given:
i = 480
r = 4% = 4/100 = 0.04
t = 6
Now, we substitute and find the value of P (initial deposit):
Hence, the initial deposit was $2000
We have that
wide=4 ft
deep=1 1/2 ft----> 3/2 ft
high=1/2 ft
we know that
surface area of the box=2*area of the base+perimeter of the base*high
area of the base=wide*deep----> 4*3/2----> 6 ft²
perimeter of the base=2*(4+1.5)---> 11 ft
surface area of the box=2*6+11*(1/2)----> 17.5 ft²
the answer is
17.5 ft²
Nearest integer because it only goes to the nearest tenth if it’s higher than 5
Answer:
a = 5
Step-by-step explanation:
Topic: Pythagorean Theorem
In this problem, we need to solve for a missing side in a right triangle using the Pythagorean theorem.
Formula:
Parts:
- a is a leg, usually the shorter side of the triangle
- b is also a leg, usually the second-longest
- c is the hypotenuse, the longest side of the entire triangle, and the distance between the endpoints of a and b
Step 1: Plug in information
We want to use the info we have and plug in the values for the variables
"a" is unknown, so we can leave it like that
"b" is the second-longest and it is a leg. In this case, it is 12
"c" is the hypotenuse and the longest side. This has a value of 13
We can use this to rewrite the equation
a² + 12² = 13²
Step 2: Solve for a
We want all terms with "a" on one side, and we want "a" alone, no exponents, nothing.
a² + 12² = 13²
a² = 13² - 12²
a = √(13² - 12²)
Step 3: Solve for a
The rest is the same, just solving the equations. Remember, square rooting and squaring are not distributive to adding and subtracting. This means that √(13² - 12²) is not 13 - 12.
a = √(13² - 12²)
a = √(169 - 144)
a = √(25)
a = 5
