On March 8, 2017, one U.S dollar was worth 66.79 Indian rupees. On that date how many rupees was 63.64 dollars worth? Round your answer to the nearest hundredth of a ripper
Answer: 4,250.52 Rupees
Step-by-step explanation:
If one U.S. dollar was worth 66.79 Indian Rupees, it means that were you to exchange both currencies, a dollar would get you 66.79 Rupees and 66.79 Rupees would get you a Dollar.
If you had $63.64 Dollars therefore, the number of Rupees you could get is the amount of dollars multiplied by the amount of Rupees:
= 63.64 * 66.79
= 4,250.52 Rupees
Find the equation for the trend line through the points (0, 11) and (100, 33). Then use it to predict the number of baskets Romy would make after practicing for 80 minutes.
Answer:
28 baskets
Step-by-step explanation:
The equation for a linear trend line is given by:
y = mx + b, where y and x are variables, m is the slope of the line and b is the y intercept (that is value of y when x is zero).
The equation of a line passing through two points [tex](x_1,y_1)\ and\ (x_2,y_2)[/tex] is:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
y represent the number of baskets made and x represents the time take. Given that the line passes through the points (0, 11) and (100, 33), hence:
[tex]y-11=\frac{33-11}{100-0}(x-0)\\\\y-11=\frac{11}{50}x\\\\y= \frac{11}{50}x+11[/tex]
The number of baskets Romy would make after practicing for 80 minutes (x = 80) is:
[tex]y=\frac{11}{50}x+11\\\\y=\frac{11}{50}(80)+11 \\\\y=17.6+11\\\\y=28.6\\\\Therefore\ y\ =\ 28\ baskets[/tex]
Heyy help please!! And explain, ty!
Answer:
9.2 x 9.2 x 9.2 (778.688)
Step-by-step explanation:
When you are looking at a cube or 3D figure, most of the time you will have to multiply by the base, length, and height. Since this is a cube, all the sides are the same, so the base, length, and height are also the same. First multiply 9.2 x 9.2 to get 84.64. 84.64 (bxl) now must be multiplied by the height. 84.64 x 9.2 = 778.688.
If the arithmetic mean of the numbers 7, 14, 6, p, 8 and 14 is 10, find p.
Answer:
Step-by-step explanation:
Solution,
Here
Mean=10
N=6
Efx=7+14+6+p+8+14
=49+p
Now
Mean=Efx/N
or,10=49+p/6 ( Therefore,10 is multiplied to 6)
or,60=49+p
or,p=60-49
p=11

Answer:
12.8
Step-by-step explanation:
Tan 52° = x/10
x = Tan 52° * 10
x = 1.2799 × 10
x = 12.799
Rounding to the nearest tenth, we have
x = 12.8
Answer:
Step-by-step explanation:
Let's use 52 as our degree.
The adjacent side to 52 is x, and the opposite is 10.
Since it's gonna be opposite over adjacent, we need to use the Tangent ratio.
(tan)
Now let's start our calculations.
Tan52 = x/10
(Tan52)(10) = x
x = 12.79941532
Let's round that to the nearest tenth place.
x = 12.8 units
(Don't forget the degree sign for 52 in Tan52!!!)

Answer:
x ≤ -4
Step-by-step explanation:
The dot/filled-in circle is on -4, so that's where we get that part of the inequalityThe line is going to the left of -4 (going towards the negatives), so x is less than -4The dot/circle is filled in, which means it is an "or equal to" symbol (in our case it's less than or equal to)Put it all together: x ≤ -4I hope this helps!
William fills 1/3 of a water bottle in 1/15 of a minute. How much time will it take him to fill the bottle?
Answer:
1/5 minutes
Step-by-step explanation:
✓Let the X= a bottle of water
✓Let y= number of minutes it will takes to fill a bottle
We can express the given statement as
1/3 X = 1/15 mins
X= ymins
If we cross multiply the two expression above we have
X/15 mins= X/3 mins * ymins
15 mins * X * y mins= 3X
Divide both sides by X
15 mins * y= 3
Make "y" the subject of the formula
y= 3/15 mins
Divide both numerator and denominator by factor of 3.
y= 1/5 minutes
Hence, the time it will take him to fill the bottle is 1/5 minutes

Element X is a radioactive isotope such that every 27 years, its mass decreases by half. Given that the initial mass of a sample of Element X is 7900 grams, how much of the element would remain after 12 years, to the nearest whole number?
Answer:
About 5, 805 grams remaining.
Step-by-step explanation:
We are given that every 27 years, the mass of Element X decreases by half.
We can write an exponential function to model the situation. The standard exponential function is given by:
[tex]\displaystyle f(t)=a(r)^t[/tex]
Where a is the initial amount, r is the rate, and t is the time, in this case years.
Since it is halved, our rate r is 1/2.
Since it is halved for every 27 years, for t, it will be t/27.
Therefore, our function is:
[tex]\displaystyle f(t)=a\Big(\frac{1}{2}\Big)^{t/27}[/tex]
Our initial sample is 7,900 grams. Hence, a = 7900:
[tex]\displaystyle f(t)=7900\Big(\frac{1}{2}\Big)^{t/27}[/tex]
We want to find the remaining amount after 12 years. So, t = 12. Use a calculator:
[tex]\displaystyle f(12)=7900\Big(\frac{1}{2}\Big)^{12/27}\approx5805\text{ grams}[/tex]
After 12 years, there will be about 5805 grams remaining.
Answer:
About 5, 805 grams remaining.
Step-by-step explanation:
We are given that every 27 years, the mass of Element X decreases by half.
We can write an exponential function to model the situation. The standard exponential function is given by:
→ f(t)=a(r)^t
Where a is the initial amount, r is the rate, and t is the time, in this case years.
Since it is halved, our rate r is 1/2.
Since it is halved for every 27 years, for t, it will be t/27.
Therefore, our function is:
→ f(t)=a(1/2)^t/27
Our initial sample is 7,900 grams. Hence, a = 7900:
→ f(t)=7900(1/2)^t/27
We want to find the remaining amount after 12 years. So, t = 12. Use a calculator:
→ f(12)=7900(1/2)^12/27 ≈5805 grams
After 12 years, there will be about 5805 grams remaining.

Using just yes or no, can you make more than one triangle when you are given 3 different line segments?
Answer:
No
Step-by-step explanation:
A triangle is made up of three line segments therefore, it would be impossible to make multiple triangles with only 3 line segments. You could stretch the line segments but they would never make other triangles since each attempt would be missing one line segment. What can be done with these 3 line segments is making more than one type of triangle. For example, we can make acute triangles, an obtuse triangle, right triangles, etc.

Point D is the in center of triangle ABC. Write an expression for the length x in terms of the three side lengths AB, AC, BC.
Hint: Use areas of triangles...A=1/2bh
Answer:
[tex] \underline{\boxed{x = \frac{A_r}{AC}}}[/tex]
Step-by-step explanation:
[tex]let \: the \: area \: be \to \: A_r \\ since \: the \: base =AC \\ then \: the \: height = AB \\ but \: AB = 2x \\ hence : the \: area \: A_r= \frac{1}{2} AC(2x) \\ (2x)AC = 2A_r\\ x = \frac{2(A_r)}{2(AC)} \\ \boxed{x = \frac{A_r}{AC}}[/tex]

Answer: corvette corvette
Step-by-step explanation:
The area of the swan is [tex]154.5 \ cm^2[/tex] and the perimeter of the swan is [tex]143 \ cm[/tex] .
What is area ?Area is the surface space occupied by something and is calculate by multiplying the length by the width.
What is perimeter ?Perimeter is the sum of all sides of any shape.
We have,
From the given diagram,
Area of Part [tex]A=7 cm^2[/tex]
Perimeter of Part [tex]A=12cm[/tex]
Area of Part [tex]B=24.5cm^2[/tex]
Perimeter of Part [tex]B=22cm[/tex]
Area of Part [tex]C=16cm^2[/tex]
Perimeter of Part [tex]C=16cm[/tex]
Area of Part [tex]D=45cm^2[/tex]
Perimeter of Part [tex]D=27cm[/tex]
Area of Part [tex]E=24cm^2[/tex]
Perimeter of Part [tex]E=20cm[/tex]
Area of Part [tex]F=14cm^2[/tex]
Perimeter of Part [tex]F=20cm[/tex]
Area of Part [tex]G=17.5cm^2[/tex]
Perimeter of Part [tex]G=15cm[/tex]
Area of Part [tex]H=7cm^2[/tex]
Perimeter of Part [tex]H=11cm[/tex]
Now,
The area of the swan [tex]=[/tex] area of Part [tex](A+B+C+D+E+F+G+H)[/tex]
[tex]=(7+24.5+16+45+24+14+17.5+7)\ cm^2[/tex]
[tex]= 154.5 \ cm^2[/tex]
The Perimeter of the swan [tex]=[/tex] Perimeter of Part [tex](A+B+C+D+E+F+G+H)[/tex]
[tex]=(12+22+16+27+20+20+15+11)[/tex]
[tex]=143 \ cm[/tex]
So, the area of the swan is [tex]154.5 \ cm^2[/tex] and the perimeter of the swan is [tex]143 \ cm[/tex] , which is obtained from the given diagram.
Hence, we can say that he area of the swan is [tex]154.5 \ cm^2[/tex] and the perimeter of the swan is [tex]143 \ cm[/tex] .
