First, let’s get the area of the base. To do that, we multiply 9 times 5, which gets us 45. Next, for the two sides of the triangular prism, take 7 times 5, which is 35, and multiply that by two, getting 70. Next, for the two triangles, we have to use the triangle surface area formula, which is 1/2•base•height. So, take the base and the heigh, 9, and 6, and you get 54. Since there are two triangles, we don’t have to divide it by 2. So, we add all of our sides, 54, 70, and 45, and we get 169 sq cm.

The hypotenuse of a right triangle is twice the length of one of its legs. Th length of the other leg is three feet. Find the le

IgorLugansk [536]

Let
x----> the length side of the hypotenuse
y----> the length side of the <span>unknown leg

we know that
x=2*y----> equation 1
applying the Pythagoras Theorem
x</span>²=y²+3²-----> equation 2

substitute equation 1 in equation 2
[2*y]²=y²+3²----> 4*y²-y²=9-----> 3*y²=9----> y²=3
y=√3 ft
x=2*y----> x=2*√3 ft

the answer is
<span>the lengths of the three sides are
</span>hypotenuse=2√3 ft
one leg=√3 ft
other leg=3 ft

If you deposit ₱10,000 into an account that earns 5% annual interest compounded semiannually, how long will it take until there

emmainna [20.7K]

Answer:

t = 3.69 ≈ 3. 7 years

Step-by-step explanation:

Given :

P = 10,000

r = 5%= 0.05

A = 12,000

n = 2 ( because it is compounded semi - annually )

$A = P (1 + \frac{r}{n})^{nt}\\$

$12000 = 10000(1 + \frac{0.05}{2})^{2 t}\\\\1.2 = ( 1 + \frac{0.05}{2})^{2t}\\\\1.2 = (1.025)^{2t}\\\\log \ 1.2 = 2t \ log \ 1.025\\\\2t = \frac{log 1.2 }{log 1.025} \\\\2t = \frac{0.1823}{0.0247}\\\\2t = 7.3805\\\\t = 3.69$
