How does anyone know how to prove parallel lines, especially when there are two pairs of them?

Answers

Answer:

Step-by-step explanation:

If two lines are cut by a transversal so that any pair of alternate interior angles are congruent, then the lines are parallel. If two lines are cut by a transversal so that any pair of corresponding angles are congruent, then the lines are parallel. You can use these converses to decide whether two lines are parallel.

What would an equation be for a line with a slope of 3 and a y-intercept of 7?

Answers

Answer:

y = 3x + 7

Step-by-step explanation:

Using the formula y = mx + b we can create this equation.

m = slope

b = y -intercept

based on the information provided I know that

Slope = 3

and

y-intercept = 7

Substitute:

y = mx + b

y = 3x + 7

y = 3x + 7 is the equation when the slope is 3 and the y intercept is 7.

Let us use the slope-intercept form for this, with m as the slope and b as a constant.

y = mx + b

7 = 3(0) + b  [since the y-int is 7, the x value will be zero]

b = 7

y = 3x + 7

Lindsey's cookie recipe uses 1 1/2 cups of brown sugar to make 2 dozen cookies. Lexi wants to make only 1 dozen cookies. How much brown sugar should Lexi use?

Answers

Answer:

(3/4) cups

Step-by-step explanation:

It is given that,

Lindsey's cookie recipe uses 1 1/2 cups of brown sugar to make 2 dozen cookies.

We need to find how much brown sugar should Lexi use to make only 1 dozen cookies.

2 dozen cookies = 1 1/2 cups

= 3/2 cups

For 1 dozen cookies,

[tex]\dfrac{\dfrac{3}{2}}{2}\\\\=\dfrac{3}{4}\ \text{cups}[/tex]

So, to make 1 dozen cookies, she will need (3/4) cups of brown sugar

Emir and his family ordered a meal that cost $50. Emir paid 8% sales tax and left an 18% tip on $50. What was the total cost?

Answers

Answer:

$63.00

Step-by-step explanation:

Your first step is to change the percents into fractions, you do this by moving the decimal point two times to the left.

Your equations look like this:

Tip equation: .18 * 50 = $9.00

Tax equation: .08 * 50 = $4.00

Then you just add them all up to get the total, and you get,

9+4+50 = 63

Chris labels every lattice point in the coordinate plane with the square of the distance from the point to the origin (a lattice point is a point such that both of its coordinates are integers). How many times does he label a point with the number $25$?

Answers

Answer:

4 times

Step-by-step explanation:

A lattice point may be defined as the point of intersection of two grid lines or more than two grid lines that is placed in a regularly spaced points arrays. This is called a lattice point.

In the context, Chris tries to label every lattice point in a coordinate plane with its square of distance from the point to its origin. The lattice points means that the numbers are both the integers. So for number 25, Chris has to label 4 times

because  The upper triangle is an isosceles triangle (the two sides are equal)

=> 5x + 5 = 45°

<=> x = (45 - 5) : 5

<=> x = 40:5 = 8

Step-by-step explanation:

Answer:

x = 8

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 given angles and equate to 180

5x + 5 + 5x + 5 + 90 = 180, that is

10x + 100 = 180 ( subtract 100 from both sides )

10x = 80 ( divide both sides by 10 )

x = 8

After buying a pair of sneakers, Ben has $12 left which is 20% of what he started with. How much money did Ben have before he bought his pair of sneakers?

Answers

Answer: $60

Step-by-step explanation:

Given that:

Amount left after purchasing sneakers = $12

$12 is equivalent to 20% of the initial starting amount

Let starting amount = x

20% of x = $12

0.2x = $12

Divide through by 0.2

0.2x / 0.2 = $12 / 0.2

x = $60

Hence, starting amount before buying sneakers is $60

The sunshine ski shop makes a profit of $40 on each pair of skis sold. Shop expenses for one week are 2,480. What is the minimum number of pairs of skis that must be sold in one week to make profit of at least $2,000

Answers

Answer:

Number of units to sell= 112 units

Step-by-step explanation:

Giving the following information:

Unitary contribution margin= $40

Fixed costs= $2,480

Desired profit= $2,000

To calculate the number of units to be sold, we need to use the following formula:

Break-even point in units= (fixed costs + desired profit) / contribution margin per unit

Break-even point in units= (2,480 + 2,000) / 40

Break-even point in units= 112 units

Answer:

Answers

Answer:

[tex]Fraction = \frac{2}{5}[/tex]

Step-by-step explanation:

Given

[tex]Blue = 4[/tex]

[tex]White = 6[/tex]

Required

Determine the fraction that are not white

First, we need to determine the total

[tex]Total = Blue + White[/tex]

[tex]Total = 4 + 6[/tex]

[tex]Total = 10[/tex]

Not white, in this case means blue.

So, the fraction is calculated as thus:

[tex]Fraction = \frac{Not\ White}{Total}[/tex]

[tex]Fraction = \frac{Blue}{Total}[/tex]

[tex]Fraction = \frac{4}{10}[/tex]

Simplify

[tex]Fraction = \frac{2}{5}[/tex]

Hence the fraction that are not white is

[tex]Fraction = \frac{2}{5}[/tex]
