Hello. Firstly you have to remembet that the sum of the three angles in any triangle is 180grades
So, determining the constant (k) you will have:
2:9:1
2k+9k+1k=180
12k=180 180/12=k
k = 15
Multiply the constant by 180 and divide by the given ratio:
180*15 / 2
180*15 / 9 etc
then your angles are
2:9:1
24:108:12

Ede4ka [16]

Answer:

64/729

or 0.088 to 3 decimal places.

Step-by-step explanation:

The probability of no 2 and no 3 on one throw of the dices = 4/6 = 2/3.

For 6 rolls we multiply this 6 times because each throw is independent.

The answer is (2/3)^6

= 64/729

or 0.088 to 3 decimal places.

Answer:

$675000

Step-by-step explanation:

Total proportion=3+1+2=6

Proportion of cars is 3/6=1/2

If cars are 1/2 and represents 27 vehicles, total vehicles sold will be 27/0.5=54 vehicles

Average price of sales is $12500 hence total sales is 12500*54=$675000

Therefore, the value of sales is $675000

Mito bakes biscuits. he uses 1/4 cup of flour to coat the countertop and the rolling pin. He also uses 2 1/2 cups of flour for e

Gennadij [26K]

Answer:

Mito can bake 3 batches of cookies.

The amount of flour used to bake cookies = Total flour used - Amount of flour used to coven counter top.

Step-by-step explanation:

Here, the amount of flour used to coat counter top and rolling pin = 1/4 cup

1/4 cup = 0.25 cup

Now, the amount of cup used to bake 1 batch of cookies = 2 1/2 cup

Now, 2 1/2 cup = ( 2 + 1/2 )cup = 2 + 0.5 = 2.5 cup

So, 1 batch of cookies = 2.5 cup

Total amount of flour used = 7 3/4 cups

Now, 7 3/4 cup = (7 + 3/4) cup = 7 + 0.75 = 7.75 cups

The actual amount of flour used to bake cookies

= Total flour used - Amount of flour used to coven counter top.

= 7.75 cup - 0.25 cup = 7.5 cup

Now, the number of batches baked with 7.5 cup $= \frac{\textrm{Total amount of flour used in baking}}{\textrm{Flour used in 1 batch}}$

$= \frac{7.5}{2.5} = 3$

or, the number of batches baked with 7.5 cup is 3 batches.

Hence, Mito can bake 3 batches of cookies.
