Answer:

1)24.25

2)21

Step-by-step explanation:

1) (a/4)^2=(20/4)^2=25

b/2/8=6/8=3/4

25-3/4

=100/4-3/4

=97/4

=24.25

2)2(x-y)^2=2(3)^2=18

x-y=3

=18+3

=21

Hope this helps!

Answer:

y = 3x - 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 3x + 2 ← is in slope- intercept form

with slope m = 3

Parallel lines have equal slopes, then

y = 3x + c ← is the partial equation

To find c substitute (1, 1) into the partial equation

1 = 3 + c ⇒ c = 1 - 3 = - 2

y = 3x - 2 ← equation of line

Answer:

Since all angles of a triangle add up to 180 degrees, b+2b+(b+24)=180

b=39 degrees

Step-by-step explanation:

b+2b+(b+24)=180

4b=156

Answer:

4 skate boards

Step-by-step explanation:

We solve this question using Greatest Common Factor method

We find the factors of 8, 12 and 16

The factors of 8 are: 1, 2, 4, 8

The factors of 12 are: 1, 2, 3, 4, 6, 12

The factors of 16 are: 1, 2, 4, 8, 16

Then the greatest common factor is 4.

Thereeft, ,the greatest number of skate boards that can be put in a section is 4 skate boards

Answer: plane a because it was 10.46 miles away

Step-by-step explanation:

Answer:

7 ÷ 9 = 0.77777777777

= 0.778

The given fraction 7/9 as a decimal rounded to 3 decimal places is 0.778.

A fraction is defined as a numerical representation of a part of a whole that represents a rational number.

To convert a fraction to a decimal, we need to divide the numerator by the denominator.

Here, we have:

7/9 = 0.777777...

7 divided by 9 gives us a repeating decimal of 0.7777777... and so on.

To round this to 3 decimal places, we need to look at the fourth decimal place. If it is 5 or greater, we round up the third decimal place. If it is less than 5, we simply leave the third decimal place as is.

In this case, the fourth decimal place is a 7, which means we need to round up the third decimal place.

Therefore, 7/9 as a decimal rounded to 3 decimal places is 0.778.

Answer:  

Home 30, visitor 17.

Step-by-step explanation:

Visiting team score is x. Home score is then x+13. Total of both is 47 so...

x+(x+13)=47

2x+13=47

2x-34

x=17

x+13=30

The score of  Home Team is 30 points.

The score of Visiting team is 17 points.

Here,

During the last schools football game, the Home Team scored 13 more points than the Visiting team.

The total of their scores was 47.

We have to find points of each team score.

What is Number system?

A number system is a system representing numbers. It is also called the system of numeration.

Now,

Let Visiting team score x points.

Then, Home team score is 13 more points than the Visiting team.

Home team score x + 13 points.

The total of their scores was 47.

Hence,

x + (x + 13) = 47

2x + 13 = 47

2x = 47 - 13

2x = 34

x = 17

So, The score of Visiting team is 17 points.

And, The score of  Home Team = 17 + 13 = 30 points.

Answer:

The coordinates of the point b are:

b(x₂, y₂)  = (-5, -1)

Step-by-step explanation:

Given

As m is the midpoint, so

m(x, y) = m (-7, -2.5)

The other point a is given by

a(x₁, y₁) = a(-9, -4)

To determine

We need to determine the coordinates of the point b

= ?

Using the midpoint formula

[tex]\left(x,\:y\right)=\left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)[/tex]

substituting (x, y) = (-7, -2.5), (x₁, y₁) = (-9, -4)

[tex]\left(-7,\:-2.5\right)=\left(\frac{x_2+\left(-9\right)}{2},\:\:\frac{y_2+\left(-4\right)}{2}\right)[/tex]

Thus equvating,

Determining the x-coordinate of b

[x₂ + (-9)] / 2 = -7

x₂ + (-9) = -14

x₂ - 9 = -14

adding 9 to both sides

x₂ - 9 + 9 = -14 + 9

x₂ = -5

Determining the y-coordinate of b

[y₂ + (-4)] / 2 = -2.5

y₂ + (-4) = -2.5(2)

y₂ - 4 = -5

adding 4 to both sides

y₂ - 4 + 4 = -5 + 4

y₂ = -1

Therefore, the coordinates of the point b are:

b(x₂, y₂)  = (-5, -1)
