Answer:
90
Step-by-step explanation:
DM=1/4 of MBND
a circle =360
360÷4=90
Answer:
Width = 4 cm
Step-by-step explanation:
The formula for area of a rectangle is length x width. You have the length (10), leaving you with this equation.
10 x ? = 40
Solve for x, or in other words, divide 40 by 10. This gives you 4. This means that 10 x 4 equals 40 cm^2
Factor and set each factor equal to zero:
x = -3, 3, 2i, -2i
There is so solution to this problem
okay. the point has an x and y value. place them into the equation.
1=m(1)+b
m=slope, and theequation tells you that slope is 7.
1=7(1)+b
now you need to figure out what b is.
1=7(1)+b
^
1= 7 +b
-7 -7
---------------
-6=B
b is 6. now place it into the equation, replacing the x and y values back.
y=7x-6.
write 7 and 6 in the boxes (the negative for the six has already been provided)
