Max buys a new laptop the original price is $800 he got it on sale for 30% off the original price how much money does he actually pay for the laptop

### Answers

Max got it for $240. Thats what he actually paid.

They would take off $240 because of the 30% off. It would come out to $560 that he paid for the laptop.

800/x=100/30

(800/x)*x=(100/30)*x

800=3.33333333333*x

800/3.33333333333=x

240=x

x=240

$800-$240=$560 that he paid.

< A and < B are complementary and congruent. What is the measure of each of these angles? 90°

45°

50°

180°

### Answers

Answer:

< A = < B = 45°

Step-by-step explanation:

First, you have to both concepts: congruent and complementary.

We say two angles are complementary when together they made a 90° angle.

We say two angles are congruent when both have the same amplitude.

For two angles to be complementarity and congruent both have to be the same and together be 90°

So 90°/2=45°

Both angles are 45°

complementary , sum of both angles = 90

congruent

Elizabeth ran 36 meters. Haruki ran 8 fewer meters than Elizabeth. Delilah ran 3 fewer meters than Haruki. How many meters did Delilah run? Explain your thinking

### Answers

36-8 is 28 which is Haruki's distance and his distance minus 3 is delilahs distance which is 25 meters

25 meters because 8 fewer meters for the girl is 28 and 3 fewer meter from the boy is 25 so basically ur just subtracting 8 from 36 which is 28 ans the. 3 from 28 which is 25

Translate the triangle (1,-4) (4,-3) (4,-8) 3 units left and 3 units up. What are the new vertices?

### Answers

9514 1404 393

Answer:

(-2, -1), (1, 0), (1, -5)

Step-by-step explanation:

Translation 3 units left subtracts 3 from each x-coordinate.

Translation 3 units up adds 3 to each y-coordinate.

(x, y) ⇒ (x -3, y +3)

(1, -4) ⇒ (1 -3), -4 +3) = (-2, -1)

(4, -3) ⇒ (4 -3, -3 +3) = (1, 0)

(4, -8) ⇒ (4 -3, -8 +3) = (1, -5)

An equilateral triangle has symmetry with respect to a line containing an altitude of the triangle. true or false?

### Answers

Answer: True

Step-by-step explanation:

An equilateral triangle is a triangle with all its three sides are equal.

When we divide it into two equal halves, there will obtain a line of symmetry.

This line of symmetry is the perpendicular bisector of the side of triangle and thus it is the altitude of the triangle.

Therefore, its true that an equilateral triangle has symmetry with respect to a line containing an altitude of the triangle.

True because all sides are equal

Select the letter of the best answer choice. Use 3.14 or 22/7 for π what is the circumference of a circle with a diameter of 21 ft? round your answer to the nearest foot.

A) 132 ft

B) 66 ft

C) 44 ft

D) 33 ft

### Answers

Because C= d x pi, plug it in, C = 21ft x 3.14, C = 65.94 ft, which is rounded to 66ft, your answer is B.

3.14 x 21 = 65.94 (which rounds up to 66)

Your answer is B, 66.

Bryan is making a cake.He uses 2/3 of a cup of sugar and 2 cups of flour.How much sugar is used per cup of flour

### Answers

The amount of sugar needed per cup of flour is 1 / 3 cup.

What is fraction?

Only verbal descriptions of a portion of the whole were used to write fractions in ancient Rome. The numerator and denominator of fractions is first written in India with one number above the other but without a line. The line used to divide the numerator and the denominator were only added by Arabs.

Given:

Bryan uses 2/3 of a cup of sugar and 2 cups of flour,

Calculate the amount of sugar as shown below,

The amount of sugar = Amount of sugar for 2 cups flour / amount of flour

The amount of sugar = 2 / 3 / 2

The amount of sugar = 2 / 6

The amount of sugar = 1 / 3

Thus, the sugar needed is 1 / 3.

### What is a section of a circle with both endpoints on the circle called? ›

**A chord** is a line segment with both endpoints on the circle. A portion of a circle is called an arc.

**What are sections of a circle called? ›**

What are the parts of a circle? The parts of a circle are the **radius, diameter, circumference, arc, chord, secant, tangent, sector and segment**. Circle terms.

**What part of the circle has two endpoints and goes through the center? ›**

A line segment that crosses the circle by passing through its center is called **a diameter**. The diameter is twice the length of the radius.

**What is a circle in two points called? ›**

By the definition, a line intersecting a circle in two points is called a **secant line**.

**What is the endpoint of a circle called? ›**

**Radius**: Any segment with one endpoint at the center of the circle and the other endpoint on the circle is a radius.

**What is the arc in a circle? ›**

In mathematics, an arc is defined as **a portion of the boundary of a circle or a curve**. It can also be referred to as an open curve. The boundary of a circle is the perimeter or the distance around a circle, also known as the circumference.

**What is the major arc of a circle? ›**

**An arc whose measure is greater than 180 degrees** is called a major arc. An arc whose measure equals 180 degrees is called a semicircle, since it divides the circle in two.

**Is a piece of a circle between two points called an arc? ›**

A chord of the circle is the line segment joining any two points on the circle. **The part of the circumference subtended by the chord** is called the arc of the chord.

**What are the different types of arcs in a circle? ›**

- Minor Arcs (two capital letters) Arcs that have a degree measure of less than 180 degrees.
- Major Arc (three capital letters) Arcs that have a degree measure greater than 180 degrees.
- Semi Circle (three capital letters) Arcs that have a degree measure equal to 180 degrees.

### How do you describe an arc? ›

In general, an arc is **any smooth curve joining two points**. The length of an arc is known as its arc length. In a graph, a graph arc is an ordered pair of adjacent vertices. In particular, an arc is any portion (other than the entire curve) of the circumference of a circle.

**How many arcs are in circle? ›**

A diameter of a circle divides it into **two equal arcs**. Each of the arcs is known as a semi-circle. So, there are two semi-circles in a full circle. The degree measure of each of the semi-circles is 180 degrees.

**What are the sections of an arc? ›**

**The region enclosed by an arc and a chord is called the segment of the circle**. The region bounded by the chord and the major arc is called the major segment and the region bounded by the chord and the minor arc is called the minor segment.

**What is called radius? ›**

Radius of a circle is **the distance from the center of the circle to any point on it's circumference**. It is usually denoted by 'R' or 'r'. This quantity has importance in almost all circle-related formulas. The area and circumference of a circle are also measured in terms of radius. Circumference of circle = 2π (Radius)

**What are the endpoints of the edge of the circle? ›**

**Diameter** – A segment that goes through the center of the circle, with both endpoints on the edge of the circle. Chord - A line segment that goes from one point to another on the circle's circumference. Tangent – a line that intersects a circle at only one point.
