What are an example and data?
Text, observations, figures, photos, numbers, graphs, and symbols can all be used as forms of data. Individual prices, weights, addresses, ages, names, temperatures, dates, or distances, for instance, might be included in the data.
Data is a basic type of knowledge and has no meaning or use by itself.
Sending rate = 1000 bps
Rate of 1000 bps means that data is sent at a rate of 1000 bits per second
Hence, to send out 10 bits
1000 bits = 1 second
10 bits = x
1000x = 10
x = 10 / 1000

Cameron and Lindsey need to make 160 cookies for the bake sale. Cameron made 2/5 of the cookies Lindsey made 16 cookies What fraction of the cookies do they still need to make?
The fraction of the cookies do they still need to made after Cameron and Lindsey made 80 cookies is 1/2.
Fractions are referred to as the components of a whole in mathematics. A single thing or a collection of objects might be the entire. When we cut a slice of cake in real life from the entire cake, the part represents the percent of the cake. The word "fraction" is derived from Roman. "Fractus" means "broken" in Latin.
The fraction was expressed verbally in earlier times. It was afterwards presented in numerical form. A piece or sector of any quantity is another name for the fraction.
Total cookies to be made is 160
Out of which Cameron made 2/5 of the cookies so,
2/5 x 160 = 64 cookies are made by Cameron
Lindsey made 16 cookies
So total cookies that still need to be made is,
= 160 - (64 + 16) = 80
The fraction of cookies still need to made is 80/160 = 1/2 .

Answer:
d = 47°
Step-by-step explanation:
Image is attached
Sum of angles drawn along a straight line = 180°:
The angle drawn in pink : 180° - 112° = 68°
The angle drawn in green: 180° - 66° = 114°
The angle drawn in yellowish orange: 180° - 23° = 157°
The angle marked in purple: 180° - 102° = 78°
The figure drawn in the center is a 5-sided irregular pentagon
∴ Sum of interior angles in a 5-sided polygon = (n - 2) ×180°
= (5 - 2) × 180°
= 540°
The four angles calculated above will assist in calculating the fifth remaining angle of the pentagon (which is marked in light blue):
68° + 114° + 78° + 157° + angle in light blue = 540°
Angle in light blue = 540° - 68° - 114° - 78° - 157°
= 123°
Sum of angles drawn along a straight line = 180°:
Angle marked in dark blue = 180° - 123°
= 57°
Now focus on the angles present inside the triangle
Sum of interior angles of a triangle = 180°
= d + 76° + 57° = 180°
d has to be isolated and made the subject of the equation:
d = 180° - 76° - 57°
d = 47°

Sarah's charges per hour for working during the week will be $9.5.
What is the solution to the equation?The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.
Sarah is a nanny who bills clients at various prices depending on whether she is working during the week or on the weekend. She worked 45 hours in a single week for a salary of $902.50, of which 5 hours were on the weekend. She worked 50 hours the next week, 10 of which were on the weekend, and made 1045 dollars.
Let x be the charge per working hour and y be the number of charges per hour during the weekend. Then the equation will be
45x + 5y = 902.5 ...1
50x + 10y = 1045
25x + 5y = 522.5 ...2
Subtract equation 2 from equation 1, then we have
45x - 25x = 902.5 - 522.5
20x = 380
x = 19
And the value of y will be
25 (19) + 5y = 522.5
475 + 5y = 522.5
5y = 47.5
y = 9.5

The length of ST is 3.61 units.
The length of TU is 3.16 units.
How to find the length of ST and TU?Distance between two points is the length of the line segment that connects the two points in a plane.
The formula to find the distance between the two points is usually given by:
d=√((x₂ – x₁)² + (y₂ – y₁)²)
Length of ST:
The coordinates of S and T are:
S(0, 0) : x₁ = 0 , y₁ = -5
T(2, 3) : x₂ = 2 , y₂ = -2
Using the distance formula with the given values:
d=√((x₂ – x₁)² + (y₂ – y₁)²)
d=√((2 – 0)² + (-2 – (-5))²) = 3.61 units
Thus, the length of ST is 3.61 units.
Length of TU:
The coordinates of S and T are:
T(0, 0) : x₁ = 2 , y₁ = -2
U(2, 3) : x₂ = 3 , y₂ = -5
Using the distance formula with the given values:
d=√((x₂ – x₁)² + (y₂ – y₁)²)
d=√((3 – 2)² + (-5 – (-2))²) = 3.16 units
Thus, the length of ST is 3.16 units.

Solve the proportion for x. When applicable, simplify all radicals and show all of your
3/X = x/4
The simplified radical for the given equation is 2√3.
The given equation is \(\frac{3}{x} =\frac{x}{4}\).
What are radicals?Radical of any number is the same as the root of the number. The root can be a square root, cube root, or in general, it is nth root. Thus, any expression or number that uses a root is known as a radical.
To compute for the values of x given the proportion, we can cross-multiply both sides of the equation as follows:
\(\frac{3}{x} =\frac{x}{4}\)
⇒x×x=3×4
⇒x²=12
⇒x=±√12
From this, we can see that the solutions for the equation are the positive and negative roots of 12.
By simplifying the radical, we get √12 = √(2² x 3) = 2√3
Therefore, the simplified radical for the given equation is 2√3.

An investment account was opened with an initial deposit of $14200 and earns an annual interest rate of 1.8 %, compounded continuously. How long will it take until the account is worth $40000? Enter your answer rounded to the nearest hundredth of a year
It will take approximately 8.71 years for the investment account to be worth $40,000.
To determine the time it takes for the investment account to reach $40,000, we can use the continuous compound interest formula: A = P * e^(rt), where A is the final amount, P is the initial deposit, r is the annual interest rate (in decimal form), and t is the time in years.
In this case, the initial deposit P is $14,200, the final amount A is $40,000, and the annual interest rate r is 1.8% (or 0.018 in decimal form). We need to find the value of t.
Rearranging the formula to solve for t, we have t = (ln(A/P)) / r. Substituting the given values, we get t = (ln(40000/14200)) / 0.018.
Calculating this expression, we find that t is approximately equal to 8.71 years when rounded to the nearest hundredth.
Therefore, it will take approximately 8.71 years for the investment account to be worth $40,000.

Point B is the midpoint of AC. AB=3x and AC=5x+21 . What is the value of AB?
First, let's write down what we know.
AB = 3x
AC = 5x+21
Since B is the midpoint, AB is half the length of AC. The sum of AB + AB is equal to the length of AC.
AB + AB = AC
Let's plug in our values.
3x + 3x = 5x + 21
Simplify the left side.
6x = 5x + 21
Subtract 5x from both sides.
x = 21
Now, let's plug in 21 for x in AB
