Hannah and her friend are training to run in a 2-mile race. On Monday, Hannah ran ½ mile. On Tuesday, she ran ⅕ mile farther than she ran on Monday.
a. How far did Hannah run on Tuesday?
b. If her friend ran ¾ mile on Tuesday, how many miles did the girls run in all on Tuesday?

Answers

Answer 1

Answer:

A: Hannah ran 0.7 miles on Tuesday

B: They ran 1.45 miles in total

Step-by-step explanation:

If you put all the fractions into decimal form it would be;

1/2 = 0.5

1/5 = 0.2

3.4 = 0.75

So, you add all of the decimals together;

0.5 + 0.2 = 0.7

0.7 + 0.75 = 1.45

Noah has a coupon for 30% off at his favorite clothing store . He uses it to buy a hoodie . The regular price of a hoodie is $27. What did Noah pay for the hoodie?

Answers

Answer:

$18.90

Step-by-step explanation:

The way to do percentages is actually pretty easy.

since it's taking 30% of you are left with 70%. Take 70 and divide it by 100. This gives you .70

Now what you do is you take the price of the time and multiply it by the .70

So 27.00 * .7 = 18.90

So Noah paid 18.90

6. Jenny is training for a marathon and runs and a constant rate of 6 miles per hour.
a) What is the distance, d, in miles, that Jenny runs in t hours. Write an equation to represent this situation.

Answers

Alrighty! D represents the miles. It is constant, or exact, the whole time (t).

Knowing that, we can write the equation, almost like a story.

Math: 6t=d

Words: 6 miles every hour= results in your distance.

Answer:

1. h = 11 cm

2. d = 220 km

Step-by-step explanation:

1. A = 1/2bh

Where,

A = 66 cm²

b = 12 cm

A = 1/2bh

66 = 1/2 * 12 * h

66 = 6h

h = 66/6

h = 11 cm

2. s = d/t

Where,

s = 110 km/h

t = 2h

s = d/t

110 = d/2

Cross multiply

110 * 2 = d

d = 220 km

Brian, Josh, Chad, Jordan, Ryan, and Rachel are the 6 players in a round-robin racquetballtournament. Each player will play aset against each of the other players. List all the sets that need to be played.

Answers

there are 15 sets that need to be played in the tournament. To list all the sets, we can simply list all the possible combinations of 2 players from the group of 6.

What is the combination?

In simple words, combination involves the selection of objects or things out of a larger group where order doesn't matter. The formula for combination helps to find the number of possible combinations that can be obtained by taking a subset of items from a larger set.

There are a total of 6 players in the round-robin racquetball tournament, which means that each player will play a set against each of the other 5 players.

To determine the total number of sets that need to be played, we can use the combination formula:

nC₂ = (n*(n-1))/2

where n is the number of players.

In this case, n = 6, so:

6C₂ = (6*(6-1))/2 = 15

Hence, there are 15 sets that need to be played in the tournament. To list all the sets, we can simply list all the possible combinations of 2 players from the group of 6:
