Line up the decimal points and multiply the rest like you would normally do it but drop down the decimal at the end
We know that; 1 foot = 2/3 yards and 1 yard = 3 feet
Since we are trying to find how many "yards", we can write the equation like this:
y = f/3
f = foot
Best of Luck!
Answer:
Option 1
Step-by-step explanation:
P(glasses' ^ internet) = 3/20 = 0.15
P(glassses') = 8/20 = 0.40
P(internet) = 7/20 = 0.35
(0.40×0.35) = 0.14
Area of rectangle = l × b = 16 × 8 = 128cm²
Area of 1 triangle = ½ × b × h = ½ × 2 × 2 = 2cm²
Area of 4 triangle = 2cm² × 4 = 8cm²
Area of shaded region
= Area of rectangle - Area of 4 triangle
= 128cm² - 8cm²
= 120cm²
Answer:
Option B
Option C
Step-by-step explanation:
we need to divide the coefficient of x by half since it is required for completing square, this term is added and subtracted at the same time to keep the equation intact, so we have
later we have
we know
we have
or
so we have
finally
The second is obtained by summing the two given equations
f(x)=8x-10
g(x)=3x+5
-----------------
f(x)+g(x)=11x-5
