Answer:
nonlinear because the second row isn't going up by the same number
Answer:
75 small triangles
Step-by-step explanation:
1. Reduce the ratio: 2-6 = 1-3
2. Write each of them as a fraction of a whole:
Small total = 3/(1+3) = 3/4 of the total amount
3. Multiply the ratio to get the answer: 3/4 * 100 = 75
So the lettuce went up by 0.25 or 25c, now, if we take 1.25 to be the 100%, how much is 0.25 in percentage off of it?
325/15=800/x. Cross multiply 325x and 15(800)=12000/325.
36.92 gallons of gas for 800 miles
Answer:
You can use a calculator to find all the tan, sin, cos values! Simply enter the number, for example, 52, then press the tan button! For question d, you are finding what number that decimal is the tangent of. Press the 2nd function on your calculator, and you can see that -1 beside the tan. Enter the decimal then use that button to find the reverse tangent.
tan52 = 1.2799
sin19 = 0.3256
cos34 = 0.8290
tan-1(0.9876) = 44.6426
To solve the conveyor belt problem, you'll have to use the sine of 15. (remember, sine = opposite/hypotenuse). Set up an equation:
sin15 = ?/12m
Use a calculator to find sin15, then you can solve it like algebra.
sin15 = ?/12m
sin15*12m = ?
0.2588*12m = ?
3.1056m = ?
Hope this helped :)
