Answer:
85.95 km
Step-by-step explanation:
Given that,
Alberto ran 45 kilometers on Monday.
On Tuesday, he runs 91% of the distance he ran on Monday.
We need to find how far did he run on Tuesday. It can be given by :
![T=45+45\times \dfrac{91}{100}\\\\=85.95\ km](https://tex.z-dn.net/?f=T%3D45%2B45%5Ctimes%20%5Cdfrac%7B91%7D%7B100%7D%5C%5C%5C%5C%3D85.95%5C%20km)
So, he run 85.95 km on Tuesday.
Wouldn't it be. 8 pieces because you cut each sides into two pieces so like this. —|—. You'll end up having four square pieces, but count the pieces that creates an L shape.
best wishes good luck
Answer:
495
Step-by-step explanation:
In order to find the sum of the first 18 terms you have to find the 18th term and the first term using the equation given.
a1=3(1)-1 a1=2
a18=3(18)-1 a18= 53
Then plug in 53 for an, 18 for n, and 2 in for a1 in the sum equation: Sn=n/2(a1+an)
Sn=18/2(2+53) Solve for sn= 495
Answer:
y=42-x
x=42-y
Step-by-step explanation:
x=42-y
Subtract y from both sides of the equation
y=42-x
Subtract x from both sides of the equation
Firstly , we need to draw diagram
we are given
opposite =300
adjacent =750
now, we can use tan formula
![tan(x)=\frac{300}{750}](https://tex.z-dn.net/?f=%20tan%28x%29%3D%5Cfrac%7B300%7D%7B750%7D%20%20)
now, we can find x
![x=tan^{-1}(\frac{300}{750})](https://tex.z-dn.net/?f=%20x%3Dtan%5E%7B-1%7D%28%5Cfrac%7B300%7D%7B750%7D%29%20%20)
we get
![x=21.8 degree](https://tex.z-dn.net/?f=%20x%3D21.8%20%20degree%20%20)
so,
angle of depression is 21.8 degree.....Answer
