First set up a proportion of 8/12 then set up another proportion of x/96 cross multiply to get 12x = 768
Divide by 12 to get your answer of 64
Answer:
$124
Step-by-step explanation:
If the tax value of a item that costs $310 before tax is $25, we can calculate the tax percentage by dividing the tax costs by the item value without taxes:
tax = 25/310 = 0.0806
So, for the second item, if the tax costs were $10, we can calculate the item value (this value will be called X) with the following equation:
tax = 10/X = 0.0806 -> X = 10/0.0806 = $124
Another way of solving this problem, is by rule of three:
tax of 25 for an item of $310,
tax of 10 for an item of $X
25/10 = 310/X -> X = 310*10/25 = $124
You would divide 12 by .5 so the answer is 24
Answer: Choice D
9, 30, 93, 282, 849
============================================================
Explanation:
The notation tells us that the first term is 9
The notation says that we multiply the (n-1)st term by 3, then add on 3 to get the nth term
So if we wanted the second term for instance, then we'd say
If we want the third term, then,
and so on.
The terms so far are: 9, 30, 93
You should find the fourth and fifth terms are 282 and 849 respectively if you keep this pattern going.
Therefore, the answer is choice D
Sum of all the angles in a triangle is 180°.
Therefore in ΔQRS,
R + S +Q = 180°
61° + 29° + Q = 180°
Q = 180 - 61 -29
Q = 90°
Hence option A is correct.
Hope this helps, have a nice day!
