Write the number using scientific notation:
23,000
Answers
The scientific notation representation of 23,000 is 2.3 x 10⁴
To express the number 23,000 in scientific notation, we need to move the decimal point to create a number between 1 and 10, and then multiply it by a power of 10.
Starting with 23,000, we can move the decimal point to the left four places to get 2.3. This means we divided the original number by 10,000 (10⁴). To compensate for this division, we multiply 2.3 by 10,000 in the form of 10⁴.
Thus, the scientific notation representation of 23,000 is 2.3 x 10⁴. The coefficient (2.3) is between 1 and 10, and the exponent (4) indicates the number of decimal places the original number was moved.

Step-by-step explanation:
1. B
angle A is 63 since 27+90= 117, 180-117= 63 (since a straight line is 180°)
2. 7x + 10 = 150 (since they are vertical angles)
7x = 140
x = 20
now plug in 7(20) +10
140+10=150
Jay organised a large wedding and 1/3 of them chose beef 5/12 of them chose Chicken and 69 of them chose vegetarian so how many guest were at the wedding ?
Answers
Answer:
276 Guests
Step-by-step explanation:
Calculation to determine how many guest were at the wedding
Guests that choose beef =1/3
Guests that choose chicken= 5/12
Guests that choose vegetarian=69
Now let calculate the how many guest were at the wedding
Let x represent the numbers of guest that were present at the wedding
Hence,
x/3 + 5x/12 + 69 = x
9x/12 + 69 = x
12x/12 - 9x/12 = 69
3x/12 = 69
x/4 = 69
x=69*4
x = 276 guests
Therefore the numbers of guests that were at the wedding is 276
Answer: 276
Step-by-step explanation: Let “x” be the number of guest.
1/3 x +5/12x + 69 = x Simplifying and solving for x … where x = 276
1/3(276) + 5/12(276) + 69 = 276
92 + 115 + 69 = 276

Answer:
x=2, y = -4.
or as an ordered pair it is (2, -4).
Step-by-step explanation:
-x + 6y = -26
x + 5y = -18 Add these 2 equations to eliminate x:
0 + 11y = -44
y = -44/11 = -4.
Now substitute y = -4 in the first equation:
-x + 6(-4) = -26
-x - 24 = -26
-x = -26 + 24 = -2
x = 2.
Check the result by substituting in equation 2:
x + 5y = 2 + 5(-4) = 2 - 20 = -18 - checks out.

Answers
Answer: y=5/3x-4
Step-by-step explanation:
Hi, you could find the slope with any 2 points on the line. For accuracy, I will choose the points (6, 6) and (0, -4), meaning when x =6, y=6, and when x=0, y=-4. Then you can set up an equation. Because the line on this graph is linear (meaning straight), the form of the equation would be y=ax+b. (If it was a parabola, it would be y=ax^2+bx+c).
y=mx+b (Or some people prefer y=ax+b, but the same thing).
Now, plug in the x and y values, getting:
6 = 6m+b and -4=0*m+b
When you simplify, you will get that b is -4, and then m is 5/3
So the equation is y=5/3x-4
You can plug the numbers of x and y in to check your answer.

The given graph respresents the function of y = 2cos(2x)+1
What is a graph?A graph can be defined as a pictorial representation or a diagram that represents data or values.
From the given graph we can pick the points which can tell us about the nature of the cosine function we took,
It is clear from the graph that the function plotted is 2 times greater than the standard function i.e. cos (x)
In cos (x) ⇒ we have maxima at (0, 1)
in the graph, ⇒ we have maxima at (0, 3)
there is a change in the graph concerning the standard cos graph.
Hence, the graph given is 2cos(2x)+1
2cos(2x)+1 is the function represented in the graph.
