Answer:

The measure of the angles is 45° and 135°

Step-by-step explanation:

When two lines intersect, a linear pair of angles is formed. Two angles are said to be linear if they are adjacent, so a linear pair of angles must add up to 180 degrees.

Let's call x and y the two required angles. Knowing they form a linear pair:

x+y=180

We also know one angle is 1/3 of the other angle, thus:

x=y/3

Or, equivalently:

3x=y

Substituting y into the first equation:

x+3x=180

Simplifying:

4x=180

Solving:

x=180/4=45

The other angle is:

y=3x=3\cdot 45=135

Thus the measure of the angles is 45° and 135°

Answer:

1 1/4 cups of sugar

Step-by-step explanation:

5/6 x 1 1/2 = 1 1/4

Answer:

5/4 cup of sugar.

Step-by-step explanation:

The recipe calls for 5/6 of a cup of sugar, so if you're making 1.5 times what the recipe calls for, you multiply 5/6 by 3/2 (or 1.5 if you prefer decimals) which would give you 15/12. Then simplify down to get 5/4 (or 1.25) cups of sugar.

Note: 5/4 also equals 1 1/4, they are both correct, it just depends on which way you choose to write it, or how your teacher wants you to write it.

Answer:

(0,5)

Step-by-step explanation:

3x-5y=15

Plug in 0 for y, because we are trying to find the value of x, when y is 0

so, 3x-5(0)=15

3x=15     Divide both sides by 3

x=5

so the answer in coordinate form is (0,5)

Answer:

It’s perpendicular

Step-by-step explanation:

If the slopes are the same and the y-intercepts are different, the lines are parallel. If the slopes are different, the lines are not parallel. Unlike parallel lines, perpendicular lines do intersect.

lines AB and CD are perpendicular to each other

This is all about getting the slope of a line between two coordinates.

The formula for the slope in this case is;

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

We are given coordinates of A and B as;

A(9, 2) and B(-1, 8)

Thus;

m = (8 - 2)/(-1 - 9)

m = 6/-10

m_ab = -6/10 = -3/5

For coordinates of C and D, we have;

C(-5, 16) and D(-8, 11)

Thus;

m_cd = (11 - 16)/(-8 - (-5))

m_cd = -5/-3 = 5/3

For the slopes to be parallel, they have to be equal but for the slopes to be perpendicular, one of them would have to be negative inverse of the other.

We see that; m_cd = 5/3 is same as -1/(m_ab) = -1/(-3/5) = 5/3

Thus, lines AB and CD are perpendicular to each other.

Answer:

x2 = y2/m - y1/m + x1

Step-by-step explanation:

Expand

y2 - y1 = mx2 - mx1

Rearrange

y2 - y1 + mx1 = mx2

Divide both sides by m to make x2 on its own

y2/m - y1/m + x1 (m's cancel out) = x2

Hence:

x2 = y2/m - y1/m + x1

The length of the model car is 2 feet

Paul's car is 16 feet long. To create a model of his car that is 1/8 the actual size, we need to determine the length of the scaled-down model.

To find the length of the model, we multiply the length of the actual car by the scaling factor of 1/8.

Length of the model = Length of the actual car * Scaling factor

Length of the model = 16 feet * (1/8)

Length of the model = 16 feet * 1/8

Length of the model = 16/8 feet

Length of the model = 2 feet

Therefore, the length of the model car is 2 feet. The model car is 1/8 the size of the actual car, so it measures 2 feet in length.

This scaled-down model allows Paul to create a representation of his car that is much smaller and more manageable while maintaining the same proportions as the original car.

Answer:

12/7

Step-by-step explanation:

Hello,

C is  the point (0,0)

D is the point (7,12)

So

[tex]\text{slope} =\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{12-0}{7-0}=\dfrac{12}{7}[/tex]

thanks

Answer:

12/7 possibly.

Step-by-step explanation:

Point C is (0,0) and point D is (7,12). Using the formula given, You should have something that looks like this:

[tex]\frac{(12-0)}{(7-0)}[/tex]

Then you solve:

[tex]\frac{12}{7}[/tex]

That would be your answer I believe.

Given :

Plan A will cost $2.00 per song. Plan B will require a $15 joining fee and $1.49 per song.

To Find :

When will Plan A be a less expensive option for Aubrey? When will Plan B be a less expensive option for Aubrey?

Solution :

Let, after x songs Plan A will be less expensive.

So,

2x < 15 + 1.49x

0.01x < 15

x < 29.41 i.e x < 30

Before, 30 songs Plan A will be less expensive.

After, 30 songs Plan B will be less expensive.

Hence, this is the required solution.

The solution to the inequality 3(x-4) ≥ 5x + 2 is when x = -10

Therefore, the correct answer is Option A. -10

Given data:

The inequality relation is represented as 3(x-4) ≥ 5x + 2

On simplifying the equation:

From the distributive property:

3x - 12 ≥ 5x + 2

Adding 12 on both sides:

3x ≥ 14 + 5x

Subtracting 5x on both sides:

-2x ≥ 14

Divide by -2 on both sides:

x ≤ -7

The inequality relation changes when the operand is -1.

So, the values of x should be less than -7

Hence, the solution is when x = -10, the inequality satisfies.
