I tried to answer these earlier but something glitched out. Hope this helps :)
Answer:
multiply 7 by 42
= 294
42 x 7 can be done as mental math, but that is challenging for some people.
First you need to figure out the cost of the skateboard after the discount but before the sales tax. By doing 100%-12% you figure out how much of the original cost you are paying 88%. Then you multiply 79.99(original cost) and 88%(how much you pay) which gets you 70.39. Then you figure out the sales tax by multiplying 70.39 by 6.75% which gives you 4.75(the sales tax). And the last thing you need to do is add the cost before tax(70.39) and the tax(4.75).
The skateboard costs $75.14
Answer:
Step-by-step explanation:
To find a linear model, you need to use the formula y = kx and solve that for k. k is the constant of variation, also known as the slope of a line. Hence, the word "linear".
If y = kx and y = 1010 and x = 5, then
1010 = 5k so
k = 202
The linear model, then, is
y = 202x
Answer:
Cosine Ratio
Step-by-step explanation:
Cos = adjacent / hypotenuse
43 is the adjacent and the variable is the hypotenuse.
