Answer:
-0.75k - 2.0
Step-by-step explanation:
0.25k + 1.5 − k − 3.5
Combining like terms with rational coefficients
0.25k + 1.5 - k - 3.5
Collect like terms with rational coefficients
=0.25k - k + 1.5 - 3.5
= -0.75k - 2.0
Answer equals negative zero Point seven five k minus two point zero
QS/AC=6/60=1/10
QR/AB=QR/50=1/10
QR=5
SO THAT TRIANGLE ABC IS EQUAL TO TRIANGLE QRS(2SIDES PROPORTIONAL.INC. ANGLE)
Answer:
187 cm²
Step-by-step explanation:
The bottom rectangle area is easy, it is 15*9 = 135 cm².
To find the area of the triangle, you only need the base width and its height (you don't need the hypotenuse). You can then use the formula: area triangle is base times half height.
The base width is 15-7 = 8 cm
The height is 22-9 = 13 cm
So the area of the triangle is 13*8/2 = 52 cm²
Together with the 135 of the rectangle that sums to 52+135 = 187 cm².
The area of a circle, given the circumference, is found using this formula:
A = C²/4π
Therefore,
A ≈ 451.93 cm²
