Step-by-step explanation:

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.

2 ft

Step-by-step explanation:

The height from which the beach ball was thrown happens when t = 0. So setting t = 0 to get y, we get

y = [-16(0) - 2](0 - 1)

= (-2)(-1)

= 2 ft

Therefore, the ball was thrown from a height of 2 ft.

Answer:

where is the chart?????

Answer:

(1, 1 )

Step-by-step explanation:

Given the 2 equations

2x - 4y = - 2 → (1)

3x + y = 4 → (2)

Multiplying (2) by 4 and adding the result to (1) will eliminate the y- term

12x + 4y = 16 → (3)

Add (1) and (3) term by term to eliminate y

14x + 0 = 14

14x = 14 ( divide both sides by 14 )

x = 1

Substitute x = 1 into either of the 2 equations and solve for y

Substituting into (2)

3(1) + y = 4

3 + y = 4 ( subtract 3 from both sides )

y = 1

solution is (1, 1 )

Complete question :

Runners participating in a charity event will run 2.1 km from the starting point to a water station and then run 1.75 km to the finish, as shown in the diagram below.

How much farther do runners run from the start to the water station than from the water station to the finish?

Answer:

0.35 km

Step-by-step explanation:

From start to water station = 2.1 km

From water station to finish = 1.75 km

Difference in distance = farther distance covered = (2.1 km - 1.75 km) = 0.35 km

Answer:

The perimeter is 127.1 cm

Step-by-step explanation:

30+25+25=80

(2)(3.14)(15)=94.2

94.2/2=47.1

Divide by two because of the semicircle

80+47.1=127.1

Answer:

Step-by-step explanation:

do this in two parts.  one, the rectangle,  two, the circle

the rectangle , you only have 3 sides to the rectangle.

2 * 25 = 50

1* 30 = 30

total perimeter of the rectangle = 80 cm

the circle, find the total of the circle, then since there is only half and circle,  multiply that by  1/2 or divide by 2, same thing.

perimeter of a circle is the circumference

circumference of a circle is  2[tex]\pi[/tex]r   or   diameter[tex]\pi[/tex]   ,  same thing

30[tex]\pi[/tex] = 94.24777961 cm ( the whole circle )

1/2*94.24777961 =47.1238898 cm

add the two parts

  80 + 47.1238898 = 127.1238898 cm

127.12  cm  ( rounded to two decimal places )

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: 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.

Hope this helps!
