B - 16 m2
solve:
(pi)x2^2=12.6
(pi)x3^2=28.3
28.3-12.6=15.7
round to 16
Let the number be x
2x-16=42
2x=42+16
2x= 58
x=29
not sure if it’s right!!
The decimal representation of 1/11 is 0.090909...
The pair of digits '09' repeat forever.
If you start counting the digits after the decimal point,
the odd ones are all zero, and the even ones are all 9 .
So the 44th digit after the decimal point is 9 .
Answer:
y = (5/2)x - 6
Step-by-step explanation:
We need to use slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept.
Slope is the change in y divided by the change in x. Given the two points, we can find the difference in the y-coordinates and divide that by the difference in the x-coordinates:
m = (-11 - (-1)) / (-2 - 2) = -10 / (-4) = 5/2
Now, we have:
y = (5/2)x + b
Substitute one of the given points for x and y to solve for b:
-1 = (5/2) * 2 + b
-1 = 5 + b
b = -1 - 5 = -6
The answer is y = (5/2)x - 6.
Answer:
20 tshirts and 150 keychains
Step-by-step explanation:
let tshirts be 10x and keychains be 2y
now make a Quadratic equation,
10x+2y=500
=let x = 20
=(10×20)+2y=500
=200+2y=500
=2y=300
y=300/2 = 150
therefore 20 tshirts and 150 keychains sumsup their goal of 500 dollars
