For this, you have to understand the ratios of a 30,60,90 triangle. The ratio(in order) is x, x(sqrt 3), 2x (following the 30,60,90 pattern y'know). Well, we know the length of the hypotenuse, 4.2, so let's use ratios to figure the other sides out. The ratio of AC is x and the ratio of AB is 2x, so 2x/2=x=2.1. One side down. BC has a ratio of x(sqrt 3). We already know x so we can substitute it in. We get 2.1(sqrt 3). To calculate the area, use the formula 1/2(bh). Inputting the values in, we get 1/2(2.1*(2.1(sqrt 3)). This can be calculated to around 3.82. To calculate the perimeter, take the sum of the sides. By adding the sides together, we get about 9.98. Hope you can now understand how to do these kinds of questions.
No it would be 5 because 25 divided by 5 is 5
Let's assume
amount invested is P
Since, we are given
Nolan invested equation as
Anias invested equation as
now, we can set them equal
now, we can solve for P
now, we can simplify it
So, she needed to invest $94.2322 to have the same amount of money that she has three years later........Answer
Answer:
x=8.8
Step-by-step explanation:
Cross multiply
4/5=x/11
5*x=4*11
5x=44
Divide by 5 on both sides
x=8.8
Or, multiply both sides of the equation by 11
4/5=x/11
11*4/5=x/11*11
8.8=x
Hope this helps! :)
