Answer:

$1.12

Step-by-step explanation:

One way to solve this problem is through an algebraic equation. Set up the equation like this, 10-3.28=6x. This equation works because 3.28 is subtracted from 10, which represents how much was spent in total. Then, this is equal to 6x, which represents the total cost of six keys.

So, to solve first subtract 3.28 from 10, this gives you 6.72. Then, divide both sides by 6. This equals 1.12, which is the cost of each key.

Write the equation of the line shown in point-slope form. (2,1) (3,8)
Ulleksa [173]

<u>Answer:</u>

The line equation that passes through the given points is 7x – y = 13

<u>Explanation:</u>

Given:

Two points are A(2, 1) and B(3, 8).

To find:

The line equation that passes through the given two points.

Solution:

We know that, general equation of a line passing through two points (x1, y1), (x2, y2) in point slope form is given by

\frac{(y- y1)}{(x-x_1)}= \frac{((y_2- y_1)}{(x_2- x_1 )}

{(y- y1)= \frac{((y_2- y_1)}{(x_2- x_1 )}\times(x-x_1)..........(1)

here, in our problem x1 = 3, y1 = 8, x2 = 2 and y2 = 1.

Now substitute the values in (1)

(y-8) = \frac{(1 - 8)}{(2 - 3)}\times(x- 3)

(y -8) = \frac{(- 7)}{(-1)}(x-3)

y – 8 = 7(x – 3)

y – 8 = 7x – 21  

7x – y = 21 – 8  

7x – y = 13  

Hence, the line equation that passes through the given points is 7x – y = 13

What type of triangle is triangle ABC give reasons for your answer help please I need 1 more mark But I don't know what I'm doin
ladessa [460]

Answer: isosceles

Step-by-step explanation:

By the alternate interior angles theorem, \angle CAB=50^{\circ}

Since angles in a triangle add to 180 degrees, \angle ACB=180^{\circ}-80^{\circ}-50^{\circ}=50^{\circ}

Since sides opposite equal angles in a triangle are equal, AB=BC.

So, triangle ABC is <u>isosceles</u>

Explain how you would convert a measurement given in ounces in pints
Tom [10]

Answer:

It is known that 1 pint equals 16 ounces

Step-by-step explanation:

It is known that 1 pint equals 16 ounces. Then we use this data to transform a number of ounces into pints.

Suppose we have x ounces. We want to know how many pints are these x ounces. Then we perform the following operation

x\ ounces*\frac{1\ pint}{16\ ounces}=z\ pints

Where z pints is the amount equivalent to x ounces
