Answer:

25.1 inches

Step-by-step explanation:

Radius of the circle = 4 inches

We have to calculate the value of Circumference of the circle.

The formula to calculate the circumference is:

Circumference = 2πr

We have to use π = 3.14, as said in the question:

So using the values, we get:

Circumference = 2 x 3.14 x 4 = 25.12 inches

Number of decimals in radius is zero, so we have to round the answer to one decimal place as said in the question.

Therefore, the circumference of the circle rounded to one decimal place will be 25.1 inches

The triangles shown are similar.

15, because 3 goes into 9, 3 times and, 4 goes into 12, 3 times therefore x has to follow this rule because these 2 triangles are similar and because it already gives you 5 just take 5*3=15 there is your answer enjoy!=)

Right triangle ABC is on a coordinate plane. Segment AB is on the line y = 2 and is 3 units long. Point C is on the line x = -1.
IgorLugansk [536]

Answer:

The possible y-coordinate of point C is 6

Step-by-step explanation:

The coordinate of a point is given by (x,y) where x is the horizontal distance from the origin on the x axis and y is the vertical distance from the origin.

Given Segment AB is on the line y = 2 and is 3 units long and Segment AB is on the line y = 2 and is 3 units long. The area of triangle ABC is 6 square units.

The area of a triangle = 1/2 × base × height

6 = 1/2 × 3 × height

height = (2 × 6) / 3 = 4 units

Since point C is perpendicular to line y = 2, they coordinates is either 2 + 4 = 6 or 2 - 4 = -2

The coordinate of point C is either (-1, 6) or (-1, -2)

The bill for lunch was 24.50 mr smith add a 20% tip how much did mr smith pay
miss Akunina [59]

Answer:

Mr.Smith paid $29.4.

Step-by-step explanation:

Mr.Smith paid $24.5 plus additional 20% of $24.5, and to figure out the total amount that he paid, we need to know what is 20% of $24.50.

20% of $24.50 is:

\frac{20}{100}*24.5=0.2*24.6=4.9.

Mr.Smith paid additional $4.9; therefore, the total amount he paid was

$24.5 + $4.9 = $29.4.

Mr. smith paid $29.4.
