20/25*2(5-10)=20/25*10-20 later calculate the numbers
Answer:
Basically this is because division can be thought of as how many times does the divisor have to be multiplied in order to produce the dividend.
So you would need to multiply 1 8 times in order to produce the dividend,
Similarly, 10 goes into 80 8 times. The zeros are simply cancelled out in the division.
We know that
area of the circle=pi*r²
circumference==2*pi*r----------> r=circumference/(2*pi)
circumference=25 1/7 in----> (25*7+1)/7----> 176/7 in
r=(176/7)/(2*22/7)----> r=176/44----> r=4 in
area of the circle is equal to the area of the cake
area=pi*r²---> (22/7)*4²-----> area=50.29 in²
the answer is
50.29 in²
Answer:
y = 23x-82
Step-by-step explanation:
The equation is written in the form y = mx+b
We need to find the slope
m = (y2-y1)/(x2-x1)
= (79-56)/(7-6)
= 23/1
The slope is 23
y= 23x +b
Put in a point for x and y to determine b
10 =23(4) +b
10 =92 +b
Subtract 92 from each side
10-92 = 92-92 +b
-82 =b
The equation is
y = 23x-82
