Answer:

x=4

x=17.9

Step-by-step explanation:

For the first diagram.

cos(45°)=x/4√2

x=4√2cos(45°)

x=4

For the second diagram

tan(38°)=14/x

0.781=14/x

x=14/0.781=17.9

Answer:

$31.50

Step-by-step explanation:

First you need to find out how much a single pound costs($12/8 lbs). That ends up equaling $1.50, so multiply that by 21 and you got the answer. :)

Answer:

5.) Associative Law

6.) Commutative Law

7.) Distributive Law

8.) Associative Law

9.) Distributive Law

10.)

Step-by-step explanation:

The associative law means that if all the arithmetic operations in an equation are the same, the position of the brackets do not matter and no matter which variables are associated, the result would still be the same.

The commutative law means that if all the arithmetic operations in an equation are the same, the position of the variables do not matter and no matter what order the variables are placed, the result would still be the same.

The distributive law means that whatever is outside of the bracket has to be multiplied into the variables in the bracket evenly. E.g. 1/4 (8x - 20) involves multiplying both 8x by 1/4 and 20 by 1/4.

Step-by-step explanation:

400 + 60 x 90 = 400 + 5400 = 5800

60 x 90 + 400 = 5400 + 400 = 5800

Answer: 7x + 12

Step-by-step explanation:

The price of each plan = $x

Since three of the seven friends pay an extra $4 per month for unlimited text messaging, the cost of the three friends will be:

= 3(x + 4)

The cost if the other four friends will be:

= 4 × x

= 4x

Therefore, the total cost of the seven plans will be:

= 4x + 3(x + 4)

= 4x + 3x + 12

= 7x + 12

Answer:

20

Step-by-step explanation:

Answer: 5 is made up of 5 times 1 of 5 ×4 = 20. A more mathematical way is to actually do this as a division problem of two fractions. 5 = 5 1. so divide 5 1 by 1 4. 5 1 1 4. This is a complex fraction make it simpler by multiplying both sides by the inverse of 1/4 which is 4/1.

Answer:

y = 1/2x +3/2

Step-by-step explanation:

y = mx +b plug into this equation

m = 1/2 (slope)

2 = 1/2(1) +b and solve this equation

b = 3/2

equation: y = 1/2x +3/2

180 deg rotation about the origin and a translation 2 units left

Answer:

The sum of the interior angle measures of the polygon is 540°

Step-by-step explanation:

The formula of the sum of the measures of the interior angles of a polygon is

∑m = (n - 2) × 180°, where n is the number of the sides of the polygon

In the given figure

∵ The polygon has 5 sides

∴ n = 5

→ Use the formula above to find the sum of the interior angle measures of it

∵ ∑m = (5 - 2) × 180°

∴ ∑m = 3 × 180°

∴ ∑m = 540°

∴ The sum of the interior angle measures of the polygon is 540°

The fair price of a 1900 ft² home is given by the equation A = $ 176,000

What is an Equation of a line?

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the square feet of the house be represented as x

Let the number of houses be represented as y

Let the first point be P ( 1400 , 105)

Let the second point be Q ( 1500 , 183 )

Now , the slope of the equation is given by

Slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Slope m = ( 183 - 105 ) / 1500 - 1400

Slope m = 78 / 100

Slope m = 0.78

Now , the equation of line is y - y₁ = m ( x - x₁ )

Substituting the values in the equation , we get

y - 1400 = 0.78 ( x - 105 )

On simplifying the equation , we get

y - 1400 = 0.78x - 81.9

Adding 1400 on both sides of the equation , we get

y = 0.78x + 1318.1

Therefore , the value of y is 0.78x + 1318.1

Hence , the equation of line is 0.78x + 1318.1 and the price is $ 176,000

Answer:

The equation of the parallel line is

y = 3x + 9

Step-by-step explanation:

The general equation of a straight line is given as;

y = mx + c

where m is the slope and c is the intercept

If two lines are parallel, their slopes are equal

So the slope of the new line too is 3

Using the point-slope formula

y-y1 = m(x-x1)

y-12 = 3(x-1)

y-12 = 3x-3

y = 3x-3 + 12

y = 3x + 9
