Answer:
260%
Step-by-step explanation:
To solve how much the percentage increase cost of Jo's car insurance is, we first need to list down our variables.
1st year = £245
2nd year = £883
First off, we need to find the difference of the two.
Increase = £883 - £245
Increase = £638
Now to find the percentage increase, we take our increase and divide it by our 1st year's payment and multiply it by 100.
Percentage increase =
Percentage increase =
Percentage increase = 260%
So the percentage increase of last years payment to this years payment is 260%.
Figure is missing, so i have attached it.
Answer:
it will clear the arch because the height of the archway of the bridge 5 feet from the center is approximately 12.76 ft
Step-by-step explanation:
The standard form of equation of an ellipse is;
x²/a² + y²/b² = 1
From the figure in the image attached, we can see that the radius is; a = 52/2 = 26 ft
While the value of b = 13 ft
Thus;
x²/26² + y²/13² = 1
x²/676 + y²/169 = 1
We want to find the height of the archway of the bridge 5 feet from the center.
Thus, we will plug in 5 for x to get;
5²/676 + y²/169 = 1
(25/676) + (y²/169) = 1
Multiply through by 676 to get;
25 + 4y² = 676
4y² = 676 - 25
y² = 651/4
y² = 162.75
y = 12.76 ft
Thus height of the truck is 12 ft and so it will clear the arch because the height of the archway of the bridge 5 feet from the center is approximately 12.76 ft
