Answer:
1. 1.25
2. 0.8
Step-by-step explanation:
1. 2 : 2.5 = 1.25 Ratio from P To Q - 1 : 1.25
2. 2.5 : 2 = 0.8 Ratio from Q to P - 1 : 0.8
1. All you have to do is find the corresponding sides(meaning similar) and the compare them from one to another.
Example:
I know 5 and 4 are corresponding sides because they are similar. The ratio is Q to P we can find by writing them down. It can be written like this.
5:4 is so when we multiply this ratio from any side of Q we will get the correpoding side from P.
5:4 ratio = 1 : 0.8 - So the ratio is 0.8
There this is another ratio that we can compare to.
Now let’s say we need to find when the one of the P side is 4 and what would be the corresponding side.
4 x 1.25(ratio from P to Q) = 5
We can also find when the P side is 3 what would be Q’s corresponding side. Which is the ratio from P to Q or 1.25.
So just multiply 3 by 1.25.
3 x 1.25 = 3.75
3.75 x 0.8 = 3
I'm not sure what you are looking for but I'll answer this question based on what I think is needed.
Given:
Day 1: 130
Day 2: 130 x 4 = 520
Day 3: 520 x 4 = 2,080
The exponential equation of this problem is:
V(n) = 130(4)^n
Where n is the number of days since the video was first shown.
Let us assume that 10 days have past. Total view would be:
V(n) = 130(4)^n
V(10) = 130(4)^10
V(10) = 130(1,048,576)
V(10) = 136,314,880
After 10 days, there are more than 136 Million views of the viral video.
what variable are we to find?
Answer:
3.75
terminating decimal
Step-by-step explanation:
A terminating decimal is usually defined as a decimal number that contains a finite number of digits after the decimal point.
Answer:
Denote the center of circle as O, the 2 endpoints of shaded segment as AB, then we have:
section OAB area = pi x radius^2 x (120/360) = pi x 6^2 x (1/3) = 37.7 (cm2)
Considering triangle OAB, we have OA = OB = radius, angle AOB = 120 deg. Denote OH as the height of triangle. H lies on AB.
=> Applying cosine and sine theorem in right triangle AHO:
OH = OA x cos 60 = 6 x (1/2) = 3 (cm)
AH = OA x sin 60 = 6 x (sqrt3)/2 = 5.2 (cm)
=> triangle AOB area:
A = triangle AOH area x 2
= AH x OH x (1/2) x 2 = 3 x 5.2 x (1/2) x 2 = 15.6 (cm2)
=> shaded segment area = section OAB area - triangle AOB
= 37.7 - 15.6 = ~21.1 (cm2)
Hope this helps!
