Answer:
11,700cm²
Step-by-step explanation:
Area of the triangle = 1/2*JK sin<I
Given
J = 800cm
K = 240cm
<I = 173 degrees
Substitute
Area of the triangle = 1/2 * 800 * 240 sin 173
Area of the triangle = 400 * 240sin 173
Area of the triangle = 400 * 29.25
Area of the triangle = 11,699.5
Area of the triangle to the nearest square centimeter is 11,700cm²
Answer:
mass on day 1: 3
mass on day 2: 9
mass on day 3: 27
Step-by-step explanation:
using this equation, y = 3^x, you can plug in 1, 2, and 3 for 'x' to get the value of 'y' (which represents the mass on specific days)
3^1 = 3
3^2 = 9
3^3 = 27
Answer:
a.) 36cm²
b.) 12cm²
Step-by-step explanation:
In order to find the area of the triangles, we can use the formula 1/2(base x height)
1/2(4x6) = 12
In order to find the area of the shaded region, we must first find the area of the entire rectangle, which can be found with the formula (length x width)
6 x 10 = 60
Next, we can subtract the areas of both triangles from our answer
60 - 12 - 12 = 36
AD*EB=CE*DB because cross multiplication
Answer:
x = -4
Step-by-step explanation:
Square both sides:
The square root and the square will cancel to leave simply the argument within the square root:
-5 - 2x = -1 - x
Now simply isolate the variable x:
x = -5 + 1 = -4
Check to see if x = -4 will work:
This works, so we know that x = -4 is a solution.
Hope this helps!
