Lori is running a marathon, which is 26.2 miles long. So far, she has run one-tenth of the marathon. How far has Lori run? (from the book)

Answers

Answer 1

Answer: to find how long Lori has run do 1/10 x 26.2
1/10 x 131/5
= (1x131) / (10x5)
= 131/50 or 2 and 31/50 miles long

Answer 2

Answer: She has 23.58 miles left to run because you multiply 26.2×0.1 and get 23.58.

320 girls, 180 boys what percent are girls

Answers

if we have 320 girls and 180 boys so the total number is 320 + 180 = 500 so the percent of girls will be:
320/500 = ?/100
so ? is your answer:
320 * 100 /500 = 64% :)))
i hope this is helpful
have a nice day

First add them up to to find the total. 320+180=500. 320 out of 500 is 320/500, which is 0.64, which is 64%.

Hannah drew a pattern using only equilateral triangles. Which of the following statements about an equilateral triangle is true?A) the measure of each angle is 60 degrees
B) the measure of each angle is 120 degrees
C) the measure of one of the angles is 90 degrees
D) the measure of one of the angles is more than 180 degrees

Is the answer A?

Answers

The sum of theangle of a triangle is 180 degrees. It is mentioned that Hannah drew a patternof equilateral triangles. Equilateral triangle has three equal sides. Also, itsangles are the same, having 60 degrees at each corner of the triangle. The answeris a. Letter b does not qualify to be an equilateral triangle because 120degrees times 3 is greater than 180 degrees. Letter c and d exceeds the totalnumber of angles at 180 degrees.

A) The measure of each angle is 60 degrees.

An equilateral triangle has equal angles of 60 degrees and lengths (of sides).

I have gone mind blank. How do you find area and perimeter? For squares, triangles, and polygons.

Triangle- Multiply base by the height and divide by 2
Polyon- (I forgot how to find this sorry)

Perimeter:
Square- Add all 4 sides
Triangle-Add all 3 side (a+b+c)
Polygon- Add all the sides

What is the answer to this math problem

Answers

Remember that dividing by a fraction is the same as multiplying by it's reciprocal. For example x ÷ 2/10 is the same as x * 10/2.

2÷ $(2)/(3)$ ×-6×5÷ $- (3)/(4)$
Lets convert all of the division to multiplication by using the reciprocal of the fractions
2× $(3)/(2)$ ×-6×5× $- (4)/(3)$
Simplify
3*-6*5*-4/3
-18*5*-4/3
-90*-4/3
120

Answer=120
