Answer:
60 grams
Step-by-step explanation:
For these type of questions, we can equate the ratio with the actual amounts. We will let the quantity to find be an unknown variable, such as x. Then we equate the ratios, cross multiply, and use algebra to solve.
Let grams of zinc be "x", so we can write the ratios and actual amounts as:
Then we cross multiply and solve for x, what we want to find out. Shown below:
There are 60 grams of zinc.
Answer:
A. real numbers, rational numbers
Step-by-step explanation:
An integer is a whole number, -2/15 is not whole. It is real and rational.
Answer: cos (25° + 10°)
Step-by-step explanation: The expression:
sin(25°) cos(10°) − cos(25°) sin(10°)
is associated to the expression for the cosine of the sum of two angles that is:
cos (α+β) = sinα *cosβ -cosα*sinβ
Hence if we do α = 25° and β = 10°
by subtitution we get:
cos (25° + 10°) = sin(25°) cos(10°) − cos(25°) sin(10°)
No, 5/6 is greater.
1) First, you have to get a common denominator, lets use 12
2) To get from 6 to 12 you would multiply times 2
3) Do the same to the numerator(the top number) which is to multiply 5 x 2
4) 5 x 2= 10
5) So, now your fraction has become 10/12
And let me ask you, which is bigger, 10/12 or 2/12
(10/12 is bigger and 2/12 is less)
