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.
Answer:
Step-by-step explanation:
This equation is written in slope-intercept form, meaning that the value next to the variable (7.50) is the rate (slope) and the other number is the y-intercept (9).
So you can say that you mowed the lawn at $9 up front and 7.50 every hour (or half-hour whatever you want).
Answer:
A. a testable scientific question
Answer:
$400 Altogether.
The main half of 4 is 2 , so I think they all collected 400 Dollars
so if it was 200 for Ben and collected 7 time than what he actually did
so 200 × 7
= $1400
Answer:
121 assuming that 9
is the square root of 9
Step-by-step explanation:
I plugged it into my calculator, but use PEMDAS and you can get the answer.
