9. Anna wants to take horseback riding lessons.
She is given $200 for her birthday to cover the
cost. She has to pay $20 for grooming supplies.
If the lessons are $30 an hour, how many lessons
can Anna take?

Answers

Answer 1

The answer is x = 6

Let us first define x to be the number of hours of riding lessons she can take.

X = Hours of lessons

Now, she has $200, she needs to pay $20 for grooming supplies, and the lessons cost $30 an hour. We to find the maximum amount of hours of lessons she can take, so in other words, we want to make her broke. To do this, we first convert the words into an equation:

200 - 20 - 30x = 0

Simplifying, we get

180 = 30x

x=6

During the basketball season, Cory made 21 of the 60 baskets she attempted. Krista made 16 out of 40 baskets she attempted. Paul made 17 of the 50 baskets she attempted and Sally 11 of the 55 she attempted. Who had the greatest percentages of baskets made?

Answers

Given:

Cory made 21 of the 60 baskets she attempted.

Krista made 16 out of 40 baskets she attempted.

Paul made 17 of the 50 baskets she attempted.

Sally 11 of the 55 she attempted.

To find:

Who had the greatest percentages of baskets made?

Solution:

We know that,

[tex]\text{Percentage of baskets made}=\dfrac{\text{Baskets made}}{\text{Total attempts}}\times 100[/tex]

Using this formula, we get

[tex]\text{Cory's percentage of baskets made}=\dfrac{21}{60}\times 100=35\%[/tex]

[tex]\text{Krista's percentage of baskets made}=\dfrac{16}{40}\times 100=40\%[/tex]

[tex]\text{Paul's percentage of baskets made}=\dfrac{17}{50}\times 100=34\%[/tex]

[tex]\text{Sally's percentage of baskets made}=\dfrac{11}{55}\times 100=20\%[/tex]

From the above percentages 40% is maximum.

Therefore, Krista has greatest percentage of baskets made.

Answers

9√2 is squared first.

so its 162.

now according to Pythagoras theorem,

x2+x2=162

2x^2= 162

x^2= 162÷2

x^2= 81

x= √81

x=9

in a right angled triangle, (height)^2 + (base)^2 = (hypotenuse)^2

here we have , height as X and base as X too , so; x^2 + x^2 = (9√2)^2

2(X)^2 = 162

x^2 = 162/2

X^2 = 81

X = √81 = 9

Answers

Answer:

Jordan had 18 coins. Two-thirds of the coins were dimes. How many coins were dimes?

Min had 18 quarters. He used 2/3 of the quarters to play arcade games. How many quarters did Min use?

Step-by-step explanation:

2/3 × 18

Checking all options

Sarah mixed 18 ounces of orange juice with 23 ounce of pineapple juice. How many ounces of juice did she have in all?

Ounces of orange juice = 18

Ounces of pineapple juice = 23

Total ounces of juice = 18 + 23

= 41 ounces

A container held 18 ounces of water. Two-thirds of the water leaked out of the container. How many ounces of water were left in the container?

Total water in the container = 18

Water leaked out = 2/3

Ounces of water left = 18 - 2/3(18)

= 18 - 36/3

= 18 - 12

= 6

Jordan had 18 coins. Two-thirds of the coins were dimes. How many coins were dimes?

Total Number of coins = 18

Dimes = 2/3 of 18

Number of dimes = 2/3 × 18

= 36 / 3

= 12

Min had 18 quarters. He used 2/3 of the quarters to play arcade games. How many quarters did Min use?

Total quarters = 18

Quarters used for game = 2/3 × 18

= 2/3 × 18

= 36 / 3

= 12

Answer:

m<5 = 133°

m<8 = 47°

Step-by-step explanation:

if <2 = 47°, and <5 is supplementary to <2, that means that together they both have to equal 180°. So, to get the measure of <5, you need to do 180 - 47 to get <5 = 133°.

Now, <5 (133°) is supplementary to <8, so they both have to equal 180° together. So, you must do 180 - 133 to get <8 = 47°. Or, another way to get <8 is to notice that <2 and <8 are alternate interior angles, which means they equal the same amount. So if <2 = 47°, then so does <8.
