Let's start with the formula for the area of a triangle
And for the first one, insert the numbers
To make this easier, 3×6=18, 1/2 of 18 is 9, so the answer is 9 square feet. There's all you need to complete the rest, good luck .
Answer:
76 x 29 = 2204
(76)(29) = 2204
I don't know if this is what you meant.
Answer:1
Step-by-step explanation:
Number selected, =10
Double it=20
Minus 2= 20-2=18
Triple the Total =18×3=54
Add a dozen=54+12=66
Divide by 6=66÷6=11
Subtract the number you stated with =11-10=1
Answer =1
Answer:
1. a^3/6 (15)^{1/2}
2.
a. a = 12 cm
b. V = 384 cm^3
Step-by-step explanation:
1. The volume of rectangular pyramid is given by:
b: base area = a^2
h: height
c: side edge = 2a
"h" can be calculated by using the Pitagora's theorem:
The, the volume is:
2.
a. The side base is calculated by using the Pitagora's theorem again:
b. The volume is given by:
For this case we have that by definition, the point-slope equation of a line is given by:
Where:
m: It's the slope
b: It is the cut-off point with the y axis
We have two points:
We found the slope:
Thus, the equation is of the form:
We substitute one of the points and find "b":
Finally, the equation is:
