Answer:   9/25  of a mile

=========================================================

Explanation:

Multiply the fractions 9/10 and 2/5 to get

(9/10)*(2/5)

(9*2)/(10*5)

18/50

9/25

---------------------

Here's a visual way to see what's going on. Start by drawing a rectangle of any size or shape. Cut the rectangle vertically into 10 equal slices. Then shade 9 of those slices to represent the fraction 9/10, which is how far (in miles) Lewis walked. See the diagram below. Specifically, refer to figure 1.

The friend walked 2/5 of this shaded amount. Draw 4 horizontal lines to split each vertical bar into 5 equal pieces. So we'll be forming a grid of smaller rectangles. For any given column, you'll shade exactly 2 smaller rectangles out of the 5 total. Hence the 2/5. This is shown in yellow in figure 2. The yellow region is 2 units tall by 9 units across, so we have 2*9 = 18 yellow rectangles in all. This is out of 5*10 = 50 smaller rectangles overall.

That's how we get to the fraction 18/50 which reduces to 9/25 when you divide both parts by the GCF 2.

Here are the answer choices

Answers

Answer:

150

Step-by-step explanation: multiply 10 and 12 and get your rectangle area then multiply .5( 10 and 6) then add them together and get 150

Answer:

150 ft²

Step-by-step explanation:

area for triangle A=bh/2

A= (10)(6)/2

A= 30 ft²

area for a rectangle A=bh

A= (10)(12)

A= 120 ft²

together

120 + 30 = 150 ft²

URGENT MARKING BRAINLIEST

Answers

Answer:

for the first questions: 36%

Step-by-step explanation:

To answer the first question: What percent of people chose Mexican food?

Number of people who choose mexican food: 27

Total number of people who took the survey: 24 + 27 + 9 + 15 = 75

So, 27 out of 75 people choose mexican food, or in other words 27/75. If you divide 27/75, you get the decimal 0.36. This decimal is the same thing as 36%.

The steps for the other three questions are the same.

Answer:

This is telling me that plan B is the better choice

for a certain number of minutes, but after that,

plan A is better.

Let +n+ = number of minutes of calls

with plan B

Set up an equation that makes the 2 plans equal

and then add 1 more minutes to +n+

Step-by-step explanation:

Answer:

Plan A is better if you talk at least 121 minutes per month

Step-by-step explanation:

1. Plan B is $6.50 plus 10 cents for each minute

2. Plan A is $18.50

3. For plan A to be better, one need to spend over $12 extra

4. Each minute cost 10 cents, so $12 would be 120 minutes of talk

5. Plan A is better if you talk at least 121 minutes

Answers

Answer:

True

Step-by-step explanation:

Squares are quadrilaterals with 4 congruent sides and 4 right angles, and they also have two sets of parallel sides. Parallelograms are quadrilaterals with two sets of parallel sides. Since squares must be quadrilaterals with two sets of parallel sides, then all squares are parallelograms.

A rectangle has all the properties of a parallelogram, plus the following: The diagonals are congruent.

Squares are quadrilaterals with 4 congruent sides and 4 right angles, and they also have two sets of parallel sides.

Parallelograms are quadrilaterals with two sets of parallel sides. Since squares must be quadrilaterals with two sets of parallel sides, then all squares are parallelograms. This is always true. (actually is true)
