Basically slope is how steep a straight line is and an intercept is where a line crosses the x-axis and y-axis. It's easier to use it than it is to explain it. In a slope-intercept formula (y= mx+b) m = slope and b= y-intercept. With this info you can solve different problems and graph equations.
Answer:
c =4 4/9 minutes
Step-by-step explanation:
The formula is
1/a + 1/b = 1/c where a and b is the time for each working alone and c is the time working together
1/8 + 1/10 = 1/c
Multiply by 40c to clear the fractions ( 40c is the least common multiple)
40c(1/8 + 1/10 = 1/c)
5c + 4c = 40)
9c = 40
Divide by 9
9c/9 = 40/9
c =4 4/9 minutes
The base of the prism is a 6 cm square. Any cross section parallel to the base has the same dimensions as the base, so is a 6 cm square. Its area is ...
(6 cm)² = 36 cm²
Sin(36)=a/16
16sin(36)=a
9.41=a
Answer:
The area of ΔABC is 6√6 sq. yards.
Step-by-step explanation:
The area of a triangle using the Heron's formula is:
Here <em>s</em> is given as follows:
The sides of the triangle ABC are as follows:
AB = 6 yd
BC = 7 yd
CA = 5 yd
Compute the value of <em>s</em> as follows:
Compute the area of ΔABC as follows:
Thus, the area of ΔABC is 6√6 sq. yards.
