To find a percent of a number, multiply the percent by the number.
First we find the number of pennies.
40% of 220 =
= 40% * 220
= 0.4 * 220
= 88
88 coins are pennies.
220 - 88 = 132
132 coins are not pennies.
Now we find 25% of 132.
25% of 132 =
= 25% * 132
= 0.25 * 132
= 33
33 coins are partners.
(Did you mean quarters instead of partners?)
Ok so all we need to do is divide 27mph by 60 to convert the mph to miles per minute.
27/60= .45 miles per minute
2w+2(5+2w)=33
2w+10+4w=33
6w=22
w=11/3 or 3 and 2/3
She cover more distance after rest 101.7-88.4625=13.2375
Answer:
y = -4x + 2
Step-by-step explanation:
To figure out the slope, plug the coordinates in the formula.
y2 - y1 / x2 - x1
= 6 - (-6) / -1 -2
= -4
Now you need to find the y-intercept, take the coordinates and plug them into your equation so far, which is y = -4x + b
y = -4x + b
-6 = -4(2) +b
-6 = -8 + b
2 = b
