Hmm, Its pretty blurry and nice cat but I will try for ya :D ***cant gurantee its gonna be correct***

6 3/4 =27/4
2/3= 0.666666666 (0.66)
1 3/4= 7/4
2 1/4 = 9/4

(i can't solve this im so sorry holy shoot)

Answer:

1) 0.3

2) 12

3a) 5/6

3b) 4/5

Step-by-step explanation:

1) There are;

12 white balls, 6 green balls and 2 red balls.

Total number of balls = 12 + 6 + 2 = 20

Probability of selecting a green ball at random = 6/20 = 3/10 = 0.3

2) we are told that number of marbles is 28 marbles.

Now, theoretical probability of drawing a blue marble = 3/7

This fraction is; number of favorable outcomes/number of possible outcomes.

Thus;

Number of blue marbles = 3/7 × 28 = 12 blue marbles

3a) theoretical probability is what we expect to happen.

There are 5 numbers less than 6 in the table.

Thus;

Theoretical probability of getting a number less than 6 in the next throw = 5/6

3b) Experimental probability is what actually happens.

Number of times a number less than 6 appears = 6 + 4 + 7 + 11 + 12 = 40 times

There was a total of 50 trials. Thus;

Experimental probability of getting a number less than 6 in the next throw = 40/50 = 4/5

7. Find the length of AB<br> please answer will mark brainelist :)

Julli [10]

Answer:

A) 17 m B) 20.8 m

Step-by-step explanation:

I cannot mark on the image but you can find the length of A to the bottom of the shape by subtracting 26-11

26-11 = 15

I will label the triangle as ABC (AB the length we trying to find, BC is 15 *it is angle B to the intercept of A and the bottom of the shape, AC is 8 because it is parallel to the given length 8)

AB is the hypotenuse

We can use the pythagorean theorem to find length AB (a^2 + b^2 = c^2)

a and b is the legs which is 8 and 15

8^2 + 15^2 = AB^2

64 + 225 = AB^2

289 = AB^2

√289 = AB (to undo a square, you use square roots)

√289 = 17

AB = 17 m

Now we need to find the hypotenuse of AC

the same thing, we did for problem A, use the pythagorean theorem

17^2 + 12^2 = AC^2

289 + 144 = AC^2

433 = AC^2

√433 = AC

√433 is <em>about </em>20.808...

round to the tenth as stated in the directions

AC = 20.8 m

The following list shows the items and prices for a restaurant order. Calculate the total amount if there is an 8% tax and the c

Andreas93 [3]

Answer:

Option B

The total amount is $63.31 if there is an 8% tax and the customer leaves a 20% gratuity.

Step-by-step explanation:

Given:

List of items Prices

1 Appetizer $8.59

2 Entrees $15.99 each

1 dessert $4.69

2 drinks $2.10 each

Total amount for the food order came to, $\left ( 1\times \$ 8.59 \right +2\times \$15.99+1\times \$4.69+2\times\$2.10)$ $=\left (\$ 8.59 \right + \$31.98+ \$4.69+\$4.20)$ =$49.46
