There are 30 centimeters in a foot.
and there is 60 minutes in an hour.
3 * 60 = 80
80 / 30 = 2.666666666 feet
The snail travels about two feet per hour.
Answer: 2
Answer:
Step-by-step explanation:
4y - 2(5 - y + 4) = 4y - 2(9 - y)
= 4y + 9*(-2) - y *(-2)
= 4y - 18 + 2y {Combine like terms 4y and 2y}
= 6y - 18
6y - 18 = 6*y - 6*3
= 6(y - 3)
6y- 18 = 2 *3y - 2*9
= 2(3y -9)
2(3y - 9) and 6(y- 3 ) are equivalent to 4y - 2(5- y +4)
Others are not equivalent
X=74°
Explanation: the sum of the interior angles equal 180°. We are given an isosceles triangle, which has 2 equal sides and one that isn’t. We can see that the bottom two angles are the same.
Take 180 and subtract 32. We have 148. We have two angles that we know are the same. Divide that by 2. That’s 74.
We can check that to make sure it equals 180°
32+74+74=180.
Therefore, it’s correct.
Answer:
1425
Step-by-step explanation:
∑ 1 ^30 (3n+1)=4+7+10+... 30 terms
a=4
n=30
d=7-4=3
![S_{30}=\frac{30}{2}[2 \times 4+(30-1) \times 3]\\=15[8+87]\\=15 \times 95\\=1425](https://tex.z-dn.net/?f=S_%7B30%7D%3D%5Cfrac%7B30%7D%7B2%7D%5B2%20%5Ctimes%204%2B%2830-1%29%20%5Ctimes%203%5D%5C%5C%3D15%5B8%2B87%5D%5C%5C%3D15%20%5Ctimes%2095%5C%5C%3D1425)
