Answer:

-60

Explanation:

6x(2x-5) always do what's in the parentheses first

6x(-10)

= -60

How do I calculate 30 percent off?

Take the pre-sale price.

Divide the original price by 100 and multiply it by 30.

Take this new number away from the original one.

The new number is your discounted value.

Answer:

2.5

Step-by-step explanation:

Let x be the number of hours both people baby sit and y be the number of hours that they each earn.

Sarah:

y = 10 + 2.5x

Carly:

y = 7.5 + 3.5x

You know that the number of hours should be the same (y).

10 + 2.5x = 7.5 + 3.5x

Evaluate and find x.

10 - 7.5 = 3.5x - 2.5x

x = 2.5

Answer:

The tree is less than 15 feet

Step-by-step explanation:

Given

[tex]x < 15[/tex]

Required

Interpret

The above inequality implies that the value of x is less than 15.

Since x represents the height of the tree in feet.

We can say that:

The tree is less than 15 feet

Answer:

Option (C)

Step-by-step explanation:

By the property of an exterior angle,

Exterior angle of a triangle is equal to the sum of two opposite interior angles.

(15x + 34)° = 29° + (12x + 26)°

15x + 34 = 29 + 12x + 26

15x - 12x = 55 - 34

3x = 21

x = 7

Measure of exterior angle = (15x + 34)°

                                           = 15(7) + 34

                                           = 105 + 34

                                           = 139°

Option (C) is the answer.

Answer:

78.814%

Step-by-step explanation:

mean,  = 480 points.

standard deviation, σ = 100 points.

If 560 is the minimum score, x = 560. We want the % of students who will score BELOW that. Use the formula for z-scores: [tex]z = \frac{x-u}{standard deviation}[/tex] to get the z score: (560-480)/(100) = 0.8.

Using a z-score table: the value under 0.8 is 78.814%.

Answer: 4 and 1/4

Step-by-step explanation:

1st question is 4-- count the points that fall above the line

2nd question is 2 out of 8, or 1 out of 4

there are only 2 players who played at least 17 matches AND scored about 5000. There are 8 players who played at LEAST 17 matches

Answers:

1. 4

2. ¼

Explanations:

1. the question is asking how many players were awarded more points than the prediction of the line of best fit (trend line), which can be translated to how many dots are above the line on the graph. 4 dots can be counted above the line

2. 8 players played at least 17 tournaments. of these 8 players, only 2 scored more than 5000 ranking points.

thus, to find the probability, we take 2 ÷ 8 = ¼

i hope this helps! :D

Answer:

-12x -8

Step-by-step explanation:

Substitute g(x) into h(x) so h(4x + 3) = -3(4x +3) + 1 = -12x - 9 + 1 = -12x -8

Answer:

p=-6

Step-by-step explanation:

So we need to get p by its self so we have to to divide both sides to get the answer. 7p=-42 so p= -6 because we divided -42/7

Answer:

Step-by-step explanation:

2 opposite semicircle are same

diameter = 9m

radius = 4.5m --- (diameter = 1/2radius)

area of semicircle = 1/2 × π × radius²

= 1/2 × 3.14 × 4.5×4.5

= 31.79m²

2 semicircles area = 31.79 × 2

= 63.8m²

______________________________

______________________________

other 2 opposite semicircle are same

diameter = 20m

radius = 10m --- (diameter = 1/2radius)

area of semicircle = 1/2 × π × radius²

= 1/2 × 3.14 × 10×10

= 157m²

2 semicircles area = 157 × 2

= 314m²

______________________________

______________________________

length = 20m ----- ( given )

breadth = 9m ----- ( given )

area = length × breadth

= 20 × 9

= 180m²

______________________________

______________________________

AREA of whole figure = 63.8 + 314 + 180

= 557.8m²
