Answer:
52 7/8 pounds
Step-by-step explanation:
Find the smaller dog's weight by multiplying the larger dog's weight by 0.75:
70.5(0.75)
= 52.875 or 52 7/8 pounds
So, the smaller dog weighs 52 7/8 pounds
The required weight of the smaller dog is 52.875 pounds.
Given that,
Doug has two German Shepherds. The larger dog weighs 70 1/2 pounds. If the smaller dog weighs 75% as much as the larger dog, To find the smaller dog's weight.
In mathematics, it deals with numbers of operations according to the statements.
What is percentages?The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.
Here,
Let the weight of the smaller dog be x,
The weight of the smaller dog is 75% of the larger dog
x = 75% of 70 1/2
x = 0.75 * 70.5
x = 52.875
Thus, the required weight of the smaller dog is 52.875 pounds.

Lions were introduced in the park in 2010. In 2012, the park has a population of 32 lions. A year later, in 2013, the park has 128 lions. Write an exponential function that models this situation. Let x represent the number of years since 2010 and let f(x)represent the number of lions.
Answer:
y = 2(4^(x))
Step-by-step explanation:
In 2012, the park has a population of 32 lions. A year later, in 2013, the park has 128 lions.
This means in 2012, it was 2^(5) lions while after 1 year it was 2^(7) lions
Thus, it increases every year by a ratio of 2^(2)
Thus, in 2011, it was 2^(5) - 2^(2) = 2^(3) lions
In 2010, it was 2^(3) - 2^(2) = 2
Since Lions were introduced in the park in 2010, using f(x), it means;
at x = 0, f(x) = 2
at x = 1, f(x) = 2^(3)
at x = 2, f(x) = 2^(5)
at x = 3, f(x) = 2^(7)
To find an exponential function that models the situation, let's use the generic formula: y = ab^(x)
At x = 0 and y = 2, we have;
2 = a × b^(0)
Thus,a = 2
At x = 1, y = 2^(3)
Thus; 2^(3) = 2 × b^(1)
b = 8/2
b = 4
So the exponential equation is;
y = 2(4^(x))
You can use the fact that the given figures are expressible as 2 raised to some powers.
The exponential function modeling the number of lions to the years passed since 2010 is given as
[tex]f(x) = 2^{1+2x}[/tex]
What is an exponential function?Those functions which are expressed as some constant raised to the power of the argument called exponential function.
How to find which function can model the given condition?Since 2012 - 2010 = 2 and the number of lions = 32 = [tex]2^5[/tex]
and 2013 -2010 = 3 and the number of lions =128 = [tex]2^7[/tex]
Thus, there is increment of 2 exponent as 1 year was changed.
Thus, we have:
[tex]f(x) = 2^{2x + a}[/tex] where a might be some constant( i took this form of exponent just by trial and error. It was already visible that one year was increasing double output, thus 2x and since there was just double increase and no other effect, there might be some non variable thing(a constant) so i thought to try some variable and see if this can work)
Since at x = 2, we get 2 raised to the power 5
thus.
[tex]2(2) + a = 5\\a = 1[/tex]
Thus,
The exponential function modeling the number of lions to the years passed since 2010 is given as
[tex]f(x) = 2^{1+2x}[/tex]
You can see that this will give correct output for x = 2 and x = 3

Step-by-step explanation:
27 is pretty simple, start by multiplying both sides by 6
so we have 2(6y+1)=y-3
this equal 12y+2=y-3
Subtract 1y and 2 from both sides to get
11y=-5

Write a coordinate proof given quadrilateral ABCD with vertices A 3, 2), B (8, 2), C (5, 0), and D (0, 0).
Plot the point and graph the quadrilateral.
Graphing is pretty easy. Think of the x and y axis as a number line, you go to the right of 0 you get positive. You go to the left, you get negative. The x axis is just that, the y axis is just like a number line but flipped. You go up for positive and down for negative on the y axis. The middle point is always (0,0). To graph a shape, you just connect the points. To plot positive points you would go right and up. So to plot (8,2), you would go 8 points right on the x axis, then 2 points up on the y axis. Think of Quadrant I as 2 positive points, if both points are positive, plot them there. If you need to plot a negative point then a positive point you would go to Quadrant II. If both of the points are negative, plot them in Quadrant III. If it is a positive point then negative, go to Quadrant IV. Remember, the x axis always comes first. Always go right or left first, then up or down. You determine how many points to go right or left then up or down by the point given. Lets take another example. If you were told to plot (-1,5), that would go in Quadrant II. You would go left 1 and up 5. I explained the concept of the coordinate plane, although, I'm not sure what you mean by coordinate proof. Hope that helped :)

A can of beans has surface area 337 cm2. It's heights is 11cm. What is the radius of the circular top?
Answer:
3.66 cm
Step-by-step explanation:
r = Radius of cylinder
h = Height of the cylinder = 11 cm
A = Total surface area of the cylinder = [tex]337\ \text{cm}^2[/tex]
Total surface area of a cylinder is given by
[tex]A=2\pi r^2+2\pi rh\\\Rightarrow A=2\pi r(r+h)\\\Rightarrow \dfrac{A}{2\pi}=r^2+rh\\\Rightarrow r^2+rh-\dfrac{A}{2\pi}=0\\\Rightarrow r^2+11r-\dfrac{337}{2\pi}=0\\\Rightarrow r^2+11r-53.64=0\\\Rightarrow 100r^2+1100r-5364=0\\\Rightarrow r=\dfrac{-1100\pm \sqrt{1100^2-4\times 100\left(-5364\right)}}{2\times 100}\\\Rightarrow r=3.66,-14.65[/tex]
So, the radius of the circular top is 3.66 cm.

Halley’s Comet has an elliptical orbit with the sun at one focus and a major axis of 1,636,484,848 miles. The closest the comet comes to the sun is 54,004,000 miles. What is the maximum distance from the comet to the sun? Round to the nearest whole number.
Answer:
1582480848 miles
Step-by-step explanation:
The maximum distance is another vertex of the major axis
1,636,484,848 miles - 54,004,000 miles = 1582480848 miles
Based on the calculations, the maximum distance from the Comet to the Sun is equal to 1,582,480,848 miles.
How to calculate the maximum distance from the Comet to the Sun?In this scenario, the elliptical orbit of the Comet with respect to the Sun at one focus and a major axis is equal to 1,636,484,848 miles. Also, the closest it came to the Sun is 54,004,000 miles.
Thus, we would divide the length of the major axis by the distance between the Comet and the Sun as follows:
Maximum distance = 1,636,484,848/54,004,000
Maximum distance = 1,582,480,848 miles.

Nick and June win some money and share it in the ratio 3:1. Nick gets 30 £60 more than June. How much did they get altogether
Answer:
£120
Step-by-step explanation:
With regards to the above, the difference between the ratio is
3:1 is 2
I.e
(3 - 1) = 2
Nick gets 2 extra, which is equal to £60
Therefore,
1 share = £60/2 = £30
June gets 1 share = 1 × £30 = £30
Nick would get = 3 × £30 = £90
Therefore, the value gotten by both would be;
= £30 + £90
= £120
