Sahara started the day with $80.
She spent $60.
What fraction of her money has Sahara spent?
Give your answer as a fully simplified fraction.
Answers
Sahara has spent 3/4 of her money.
To find out what fraction of her money Sahara has spent, we need to first calculate how much money she has left after spending $60.
Starting with $80, subtracting $60 gives us $20.
Therefore, Sahara has $20 left.
To express this as a fraction, we need to use the total amount of money she started with as the denominator and the amount she has left as the numerator.
So, the fraction of her money that Sahara has spent is:
$60/$80
This can be simplified by dividing both the numerator and denominator by 20:
$60/$80 = $3/$4
Therefore, Sahara has spent 3/4 of her money.
It's important to understand fractions as they are a fundamental concept in mathematics. Fractions are a way of representing parts of a whole. The numerator represents the part of the whole that we are considering, while the denominator represents the total number of parts that make up the whole. In this case, the whole is the total amount of money Sahara started with, which was $80. The part that she spent was $60, so the fraction of her money spent is 3/4.
Fractions are used in many different mathematical operations, including addition, subtraction, multiplication, and division. It is important to be able to manipulate fractions in order to solve more complex problems in algebra and calculus.

Define Geometric MeanThe Geometric Mean (GM) in mathematics is the average value or mean that, by calculating the product of the values of the set of numbers, denotes the central tendency of the numbers. In essence, we multiply the numbers together and calculate their nth root, where n is the total number of data values. For instance, the geometric mean for a given pair of numbers, say 3 and 1, is equivalent to (3 + 1) = 3 = 1.732.In other terms, the geometric mean is the product of n numbers divided by the nth root. The geometric mean differs from the arithmetic mean, as is noted. As a result of the fact that in arithmetic mean, the data values are added before being divided by the total number of values. However, when calculating the geometric mean, we multiply the provided data values before taking the root of the entire number of data values using the radical index.

The line, y = 3x+2, is tangent to the circle with centre, C(-5,4), at the point Q.
Find the coordinates of Q.
Answers
The circle centered at C(-5,4) intersects the line y = 3x + 2 at the point Q, with coordinates (-1/10, 17/10). This point Q serves as the tangent point between the line and the circle.
To find the coordinates of the point Q where the line y = 3x + 2 is tangent to the circle with center C(-5,4), we can use the concept of the slope of a tangent line.
First, we need to find the slope of the tangent line. The slope of the line y = 3x + 2 is 3. For a tangent line to a circle, the radius drawn from the center of the circle to the point of tangency is perpendicular to the tangent line. Since the slope of the radius is the negative reciprocal of the tangent line's slope, the slope of the radius is -1/3.
Next, we find the equation of the radius line passing through the center C(-5,4) with a slope of -1/3. Using the point-slope form, we have:
y - 4 = (-1/3)(x + 5)
To find the point of tangency, we solve the system of equations formed by the line y = 3x + 2 and the radius line:
y = 3x + 2
y - 4 = (-1/3)(x + 5)
Substituting the value of y from the first equation into the second equation:
3x + 2 - 4 = (-1/3)(x + 5)
3x - 2 = (-1/3)x - 5/3
3x + (1/3)x = 5/3 - 2
(10/3)x = -1/3
x = -1/10
Substituting this value of x back into the first equation:
y = 3(-1/10) + 2
y = -3/10 + 20/10
y = 17/10
Therefore, the coordinates of the point Q, where the line y = 3x + 2 is tangent to the circle with center C(-5,4), are (-1/10, 17/10)

the terminal point p(x, y) determined by a real number t is given. find sin(t), cos(t), and tan(t). 1 5 , − 2 6 5 sin(t) = cos(t) = tan(t) =
Answers
sin(t) = -sqrt(61) / 30, cos(t) = sqrt(61) / 15, and tan(t) = -5/3.
To find sin(t), cos(t), and tan(t) we need to use the coordinates of the terminal point p(x,y) determined by the real number t.
Given that the terminal point is (1/5, -2/6), we can find the values of sin(t), cos(t), and tan(t) using the following formulas:
sin(t) = y / r
cos(t) = x / r
tan(t) = y / x
where r is the distance from the origin to the point p(x,y), which can be calculated using the Pythagorean theorem:
r = sqrt(x^2 + y^2)
Plugging in the values for the coordinates of p(x,y), we get:
r = sqrt((1/5)^2 + (-2/6)^2) = sqrt(1/25 + 4/36) = sqrt(36/900 + 25/900) = sqrt(61/900)
sin(t) = (-2/6) / (sqrt(61/900)) = -sqrt(61) / 30
cos(t) = (1/5) / (sqrt(61/900)) = sqrt(61) / 15
tan(t) = (-2/6) / (1/5) = -5/3
Therefore, sin(t) = -sqrt(61) / 30, cos(t) = sqrt(61) / 15, and tan(t) = -5/3.

In order to find out what the value of 9 must be in order to make this equation true, we must isolate the variable. That can be done by doing the opposite operation. In this case, the opposite operation would be division since d is being multiplied by 2 to get 8.
So, we have to divide both sides of the equation by 2:

What is the secant secant theorem?The secant secant theorem states when two secants drawn to a circle from a point external to the circle then the product of a secant and the external segment is equivalent to the product of the second secant and its external segment.
The secant secant rule indicates that we get;
(4 + 2) × 4 = (x - 7) × ((x - 7) + (x - 5))
Therefore;
(4 + 2) × 4 = 24 = (x - 7)² + ((x - 7) × (x - 5))
(x - 7)² + ((x - 7) × (x - 5)) = 24
2·(x - 7)·(x - 6) = 24
(x - 7)·(x - 6) = 24/2 = 12

Tim and Tom are trying to find the least number which is a perfect square and which is also divisible by 16, 18 and 45.
Answers
First, let's find the LCM of 16, 18, and 45.
Prime factorization of 16:
16 = 2^4
Prime factorization of 18:
18 = 2 * 3^2
Prime factorization of 45:
45 = 3^2 * 5
To find the LCM, we take the highest powers of all prime factors involved:
LCM = 2^4 * 3^2 * 5 = 720
Now, we need to find the smallest perfect square that is divisible by 720. We can do this by taking the square of the prime factorization with each exponent divided by 2:
720 = 2^4 * 3^2 * 5
Taking the square root of each factor:
√(2^4 * 3^2 * 5) = 2^2 * 3 * √5 = 12√5
So the smallest perfect square divisible by 16, 18, and 45 is (12√5)^2.
Calculating the square:
(12√5)^2 = (12^2) * (√5)^2 = 144 * 5 = 720.
Therefore, the least number that is a perfect square and divisible by 16, 18, and 45 is 720.

Answers
By applying the knowledge of similar triangles, the lengths of AE and AB are:
a. \(\mathbf{AE = 3.9 $ cm}\\\\\)
b. \(\mathbf{AB = 2.05 $ cm} \\\\\)
See the image in the attachment for the referred diagram.
The two triangles, triangle AEC and triangle BDC are similar triangles.Therefore, the ratio of the corresponding sides of triangles AEC and BDC will be the same.
This implies that:
AC/BC = EC/DC = AE/DBGiven:
\(EC = 8.1 $ cm\\\\DC = 5.4 $ cm\\\\DB = 2.6 cm\\\\AC = 6.15 $ cm\)
a. Find the length of AE:
EC/DC = AE/DB
Plug in the values\(\frac{8.1}{5.4} = \frac{AE}{2.6}\)
Cross multiply\(5.4 \times AE = 8.1 \times 2.6\\\\5.4 \times AE = 21.06\)
Divide both sides by 5.4\(AE = \frac{21.06}{5.4} = 3.9 $ cm\)
b. Find the length of AB:
\(AB = AC - BC\)
AC = 6.15 cm
To find BC, use AC/BC = EC/DC.
Plug in the values\(\frac{6.15}{BC} = \frac{8.1}{5.4}\)
Cross multiply\(BC \times 8.1 = 6.15 \times 5.4\\\\BC = \frac{6.15 \times 5.4}{8.1} \\\\BC = 4.1\)
Thus:\(AB = AC - BC\)
Substitute\(AB = 6.15 - 4.1\\\\AB = 2.05 $ cm\)
Therefore, by applying the knowledge of similar triangles, the lengths of AE and AB are:
