Answer:

Step-by-step explanation:

The triangle shown has all 3 sides equal in length, hence it is an equilateral triangle.

A property of equilateral triangles is the angles are congruent.

The sum of the 3 angles = 180°, hence the measure of each angle is

$\frac{180}{3}$ = 60° → A

Letter A. Which is letter 60 degrees. You can tell since it’s not a right angle, which gets rid of 90 degrees. It’s not 30 degrees because that would be too small. And it’s not 180 degrees because it’s too big.

The linear function graphed below represents the value of a comic book since Lucy purchased it. What was the value of the comic

zhuklara [117]

Answer:

C. $25

Step-by-step explanation:

We will find,

The slope of the function using $\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$ .

Taking the points (1,40) and (2,55).

Slope = $\frac{55-40}{2-1}$

i.e. Slope = $\frac{15}{1}$

i.e. Slope = 15

Substituting the slope and point (1,40) in the equation $y=mx+b$ ,

We have, $40=15\times 1+b$

i.e. $b=40-15$

i.e. b= 25

Thus, the equation of the linear function is $y=15x+25$ .

<em>This linear function represents the cost of the comic book since Lucy purchased it, where x= years.</em>

So, the initial value of the comic book is when x= 0.

So, $y=15\times 0+25$ i.e. y= 25

Hence, the cost of the book when Lucy purchased it was $25.

Candle food is on sale for 20% of the original price what is the discount of the key if the original price is $1.35

Evgesh-ka [11]

Hi there!

To calculate a discount or a mark-up in the price of a retail item, you need to multiply the given price of the item by the percentage, like so:

1.35 × 0.2 = 0.27

Then you add or subtract as necessary. In your case you would subtract since you are trying to find a discount price.

1.35 - 0.27 = 1.08

So the final price of the product after the discount is $1.08
