Answer:
cos∠ABC = 12/15 = 0.80
tan∠ABC = 9/12 = 0.75
sin∠ACB = 12/15 = 0.80
cos∠ACB = 9/15 = 0.60
tan∠ACB = 12/9 = 1 1/3
Step-by-step explanation:
Find the Adjacent, Opposite, or Hypotenuse angles to the angles in the picture and fill them into the given fraction.
cos∠ABC = Adjacent/Hypotenuse = 12/15 = 4/5 = 0.80
tan∠ABC = Opposite/Adjacent = 9/12 = 3/4 = 0.75
sin∠ACB = Opposite/Hypotenuse = 12/15 = 4/5 = 0.80
cos∠ACB = Adjacent/Hypotenuse = 9/15 = 3/5 = 0.60
tan∠ACB = Opposite/Adjacent = 12/9 = 1 1/3 (1 1/3 in decimal form is 1.3 with a line on top of 3 (Bar on top of 3))
Answer:
Ryan isn't correct.
Step-by-step explanation:
If Ryan wants to make exactly 3 cups of dip, he would need 3/8 pounds of chicken.
1/8(3)=3/8 pounds.
3/4, or 6/8 pounds of chicken doesn't represent 3 cups, it's for 6 cups of dip.
Answer: The large ____ holds 48 units.
For the diagram you could draw the small rectangle 4 squares wide and 9 squares long. that will represent something that holds 36 units.
For the large one make it 4 squares wide and 12 squares long. That will have spaces for 48 units.
Step-by-step explanation: Change the percent to a decimal and set up the equation that means 36 is 75% of some number, yet unknown, X is the unknown number.
36 = .75x divide both sides by .75
36/.75 = .75x/.75 . The .75 "cancels" on the right. Then use a calculator.
36 ÷ .75 = 48
x = 48
Answer:
12.5%
Step-by-step explanation:
There are two types of spinners here and the outcome of them is independent. That means
P(odd number,C) = P(odd number) * P(C)
There are two odd numbers out of four numbers in the first spinner. The chance of odd number will be:
P(odd) = 2/(2+2)= 1/2= 50%
There are four letters and the desired outcome is C. The chance for C will be:
P(C)= 1/4= 25%
Then the chance will be:
P(odd number,C) = P(odd number) * P(C)
P(odd number,C) =50% * 25% = 12.5%
A proportion is a statement that two ratios are equal
