No he did not spend 110% more time doing homework if he did it would be 12hrs to find this put 11 in its decimal form and multiply it by 110 =12.1
Step-by-step explanation:
using Pythagoras theorem
d}^{2} =4}^{2+7}^{2}
d}^{2}=16+49
d}^{2}=65
d}^{2}=√65
d=8.06 or 8
Answer:
$205
Step-by-step explanation:
The cost of bike Sarah bought = $260
Discount coupon = $55
The cost Sarah paid for the bike =$260 - $55
Use the expression 260 + (- 55) to find how much Sarah paid for her bike:
![260+(-55)\\ \\=200+60+(-55)\\ \\=200+5+55+(-55)\ [\text{Note} 55+(-55)=0]\\ \\=200+5\\ \\=205](https://tex.z-dn.net/?f=260%2B%28-55%29%5C%5C%20%5C%5C%3D200%2B60%2B%28-55%29%5C%5C%20%5C%5C%3D200%2B5%2B55%2B%28-55%29%5C%20%5B%5Ctext%7BNote%7D%2055%2B%28-55%29%3D0%5D%5C%5C%20%5C%5C%3D200%2B5%5C%5C%20%5C%5C%3D205)
So, Sarah paid $205 for the bike.
Answer:
a=35
b= 55
c=110
Step-by-step explanation:
<a = 35 since a and 35 are vertical angles
a +b = 90 = 180 since it is a triangle
35+b+90 =180
Combine like term
125 +b = 180
Subtract 125 from each side
b = 180-125
b =55
c+70 = 180 since it forms a straight line
Subtract 70 from each side
c+70-70 =180-70
c = 110
The ball costs ten cents. If the total cost is $1.10 and the bat costs $1 more than the ball then the only logical cost for the ball is $0.10 because $1 +$0.10= $1.10, which is the cost we are looking for.
