please help me with this

Answer:

1. 5.6%

2. 15%

3. 300 seats

4. 2.3%

Step-by-step explanation:

1. Percent error is A-E/E*100

A is actual and e is expected

376-356/356= 0.05618*100= 5.6%

2. 17-20/20=-0.15*100= 15%

3. This time we have to solve for the actual

x-250/250*100=20

x=300 seats

4. 342-350/350=-0.0228571429*100= 2.3%

the half of 14.6 is 7.3 and you times it by 3.14 and its 22.922 i think

Answer:

3(4+√2)

Step-by-step explanation:

Here we need to find the perimeter of the given figure. Here the given figure is made from a triangle and a square. The side lenght of the square is 3. We need to find the hypontenuse of the triangle in order to find Perimeter .

• Using Pythagoras Theorem :-

⇒ h² = p² + b²

⇒ h² = 3² + 3²

⇒ h² = 9 + 9

⇒ h² = 18

⇒ h = √[ 9 × 2 ]

⇒ h = 3√2 .

Therefore the perimeter will be ,

⇒ P = 3√2 + 3 + 3 + 3 + 3

⇒ P = 3√2 + 12

⇒ P = 3( 4 + √2)

Answer:

6216

Step-by-step explanation:

This problem deals with exponential growth.

Final value: F

Present (initial) value: P

Rate of growth: r

Time in years = t

[tex] F = P(1 + r)^t [/tex]

[tex] F = 2900(1 + 0.1)^8 [/tex]

[tex] F = 6216 [/tex]

Answer -2x^4 - 2x^3 + 22x^2 - 30x + 12

Here's your solution

=> (2x^2 - 4x + 2) - (x^2 + 3x - 6)

=> (2x^2 - 4x + 2) -x^2 - 3x + 6

=> firstly multiple whole with -x^2

=> -x^2(2x^2 - 4x + 2) = -2x^4 + 4x^3 - 2x^2

=> now with -3x

=> -3x(2x^2 - 4x + 2) = -6x^3 +12x^2 -6x

=> with 6

=> 6(2x^2 - 4x + 2) = 12x^2 - 24x + 12

=> now add all terms

=> -2x^4 - 2x^3 + 22x^2 - 30x + 12

hope it helps and your day will be full of happiness ^_^

Answer:

The point crosses over the y-axis

Step-by-step explanation:

Given

A change in the sign of x coordinate

Required

The effect on the point location

Assume the coordinate to be (x,y).

The above point is located in the first quadrant,

When the x value changes to negative i.e. (-x,y)

The point moves from the first quadrant to the second quadrant

This implies that, the point crosses over the y-axis.

Similarly, assume the coordinate to be (-x,-y).

The above point is located in the third quadrant,

When the x value changes i.e. (x,-y)

The point moves from the first quadrant to the fourth quadrant

This implies that, the point crosses over the y-axis.

Answer:

Step-by-step explanation:

The answer would be (G)

The value of w is greater than -4 which will best represent the inequality 3.3w - 9 > -22.27 on number line.

Number lines are simple, visual pictures of how the values of numbers increase and decrease.

Given an inequality 3.3w - 9 > -22.27

On solving, we get,

3.3w - 9 > -22.27

3.3w > -22.27 + 9

3.3w > -13.27

w > -4

Hence, the value of w is greater than -4 which will best represent the inequality 3.3w - 9 > -22.27 on number line.

Answer:

#12.) 3m+2=17

3(5)+2=17

5*3=15

15+2=17

Step-by-step explanation:

Answer:

3 x 2 + 5 - 4 = 7 if its not 7 then try 15 most likely 7

m = 5 its already given on the top or its 17

7 x 5 - 2 > 12, m = 5 or the answer is 33 for the left side

for this you need to draw an empty circle on two and make the line bold starting from 2 to the 10.

Answer:

Mean and Median

Step-by-step explanation:

Given the data :

285,288,289,290,299,300,308,309,312,314

To summarize the data using a measure of centre, considering that the dataset doesn't show a great deal of variation we could use either the mean or median value.

The mean, x = Σx / n

n = sample size = 10

Σx = 2994 ; n = 10

x = 2994 / 10 = 299.4

Also the median value ;

1/2 * (n + 1)th term

1/2 * (10 + 1)th term

1/2 * 11

= 5.5 th term

= (5 + 6)th / 2

= (299 + 300) / 2

= 299.5

Answer:

  4 ft = height

  10 ft = base

Step-by-step explanation:

The area of a triangle is given by ...

  A = 1/2bh

Filling in the given value, we get the relation ...

  20 = 1/2bh

  40 = bh

We know the factors of 40 are ...

  40 = 1×40 = 2×20 = 4×10 = 5×8

Of the numbers that area available, only the pair 4×10 will give the desired result.

The height is 4 ft; the base is 10 ft.

Step-by-step explanation:

Answer:

4

Step-by-step explanation:

You order all the numbers from least to greatest and the center number/s is the median.

If two numbers are in the center, you add them up and divide by 2

The median for this set was 4 and 4. We add those numbers (4+4=8) and divide the sum by 2. We get 4 as the answer
